Texas resident vs nonresident: domicile, the 183-day rule, and defending against FTB audits
Domicile vs residency: not the same thing
These two terms get used interchangeably in casual conversation but they mean different things in tax law, and the distinction matters. Domicile is your true, fixed, permanent home; the place you intend to return to whenever you’re away. You can only have one domicile at a time. Residency, depending on the state, can be a broader concept that includes physical presence over some threshold (often 183 days) without requiring the same intent. So you can be a resident of multiple states in the same year for tax purposes, but you have only one domicile.
California’s Franchise Tax Board uses a domicile-based test for residency, supplemented by a nine-month presumption. If you’re domiciled in California, you’re a California resident regardless of where you physically are. If you’re physically present in California for nine months or more in a tax year, you’re presumed to be a resident, though that presumption can be rebutted with evidence of domicile elsewhere. New York uses a similar two-prong test: domicile in New York makes you a resident, and statutory residency applies if you maintain a permanent place of abode in New York and spend more than 183 days in the state. Texas, for its part, doesn’t impose an income tax, so the Texas concept of residency only matters for property tax homestead exemptions and certain other purposes, not for income tax.
What this means for someone moving from California to Texas: you have to change your domicile, not just your physical location. Changing domicile requires both physical presence in the new state (with the intent to remain) and abandonment of the old domicile. Both parts matter. If you move to Texas but keep your California house, keep your California driver’s license, keep your California doctors, and visit California 100 days a year, the FTB can argue your domicile never actually changed. The Texas address is just a second home, and you’re still a California domiciliary for tax purposes.
The 183-day rule and how states apply it differently
The 183-day rule is the most-cited residency benchmark but it works differently in different states. In New York, the rule applies as a statutory residency test: if you maintain a permanent place of abode in New York and spend more than 183 days in New York during the tax year, you’re a New York resident for that year, regardless of domicile. A day counts even if you’re in New York for any part of the day (a 30-minute LaGuardia layover doesn’t count, but a 4-hour business meeting in Manhattan does). The 183-day rule in New York is a hard line: 183 days means resident, 182 days means nonresident (assuming domicile is elsewhere).
California has no exact 183-day statutory residency test. The state uses a domicile-based test for full-year residency and a nine-month presumption (spending nine months in California in any tax year creates a presumption of residency that you have to rebut). For partial-year residents, California taxes the portion of income earned while a California resident, with allocation rules for income earned in part inside and part outside California. The day count matters for California audit purposes, even though there’s no exact 183-day rule, because the FTB looks at total time in California as one factor in determining domicile.
Illinois uses a 183-day rule for nonresident treatment: spending more than 183 days in Illinois makes you a resident regardless of domicile elsewhere. Massachusetts, Maine, and Connecticut all have variations of statutory residency rules tied to days plus a permanent place of abode. The common thread: keeping a residence in your former state plus spending more than half the year there usually triggers resident treatment regardless of where your driver’s license says. For Texas-bound former residents, the implication is to spend less than 183 days in the former state and to either sell or genuinely relinquish use of the former-state residence.
The domicile factors states actually weigh
California’s FTB Publication 1031 lists the factors the state considers in determining domicile. The list isn’t exhaustive but it covers the main signals. Where you spend most of your time. Where your spouse and minor children live. Where you maintain your primary home. Where your vehicles are registered. Where you bank. Where your professional advisors are (doctor, dentist, lawyer, accountant). Where your children attend school. Where your social, civic, and religious organizations are. Where you’re registered to vote. Where you hold your driver’s license. The state’s position is that no single factor is dispositive, but the weight of evidence determines domicile.
New York’s DTF uses a similar but slightly different framework. New York’s audit guidance lists what’s known as the ‘five primary factors’: home, active business involvement, time, items near and dear, and family connections. The ‘items near and dear’ factor is unique to New York and refers to where you keep things of personal significance (family photos, heirlooms, pets, art collections, wine collections). The idea is that people keep their most cherished possessions at their true home. A New York audit will sometimes include a request for a list of where your most valued possessions are physically located.
The factors that tend to carry the most weight in residency audits: where you spend the most time (day count), where your family is, where your primary residence is, where you work, and where you bank. The factors that carry less weight but still matter: voter registration, driver’s license, professional advisors, club memberships, religious affiliation, social organizations, and pet veterinarian. The factors that come up in audits but don’t decide cases on their own: where your dentist is, where your kids’ school is, where your safe deposit box is. We’ve seen audits won and lost on the strength or weakness of two or three specific factors.
Documentation that proves Texas residency
If you’re moving to Texas and want to establish residency that holds up under audit, the documentation needs to be created in real time, not constructed later. Start with the change of driver’s license. Texas requires new residents to obtain a Texas license within 90 days of establishing residency. Surrender the old license at the time of the change (many states require the new state’s DMV to send the old license back, which Texas does). Save the receipt and the photo of the surrendered license if you can. Driver’s license is one of the easier factors to document because the state itself maintains the record.
Voter registration in Texas. Register to vote in Texas, and if possible, actually vote in a Texas election (primaries, runoffs, special elections, anything). Voting records are public, and being able to point to a Texas voting record from the year of the move is strong evidence. Conversely, do not vote in your former state after the move. We’ve seen audits where a single absentee ballot cast in California three months after the alleged move created the entire dispute.
Vehicle registration. Register all personally-owned vehicles in Texas. The Texas Department of Motor Vehicles maintains the registration database. Save the new registration documents. Banking relationships. Change your primary banking to a Texas address. Most national banks (Chase, Bank of America, Wells Fargo) will update the address on file and treat the Texas branch as your home branch. Move the primary checking and savings accounts. You can keep accounts at your old bank for convenience, but they shouldn’t be your primary.
Professional advisors. Change your primary care doctor, dentist, and other healthcare providers to Texas-based practices. Schedule actual appointments and document the visits. The audit will look for evidence that you’re actually receiving medical care in Texas, not just registering with a Texas doctor and continuing to see your old doctor in California. Similarly, change your accountant (we’re happy to fill this role for Texas-bound clients), your attorney for ongoing matters, and your financial advisor if applicable.
Real estate. Either sell the former-state home or convert it to a genuine rental at fair market rent to an unrelated tenant. Keeping the home empty and using it occasionally is the worst possible setup for residency purposes; it looks like you maintained a permanent place of abode. If you must keep the home for business or family reasons, document the use carefully and limit your time there. New York audits in particular focus heavily on whether the former-state residence was ‘maintained’ for the taxpayer’s use.
Family. If you’re married, both spouses need to move. If one spouse stays in California and the other establishes Texas residency, the FTB will likely treat both as California residents, especially if the spouses file jointly. If children are involved, they should enroll in Texas schools at the time of the move. Documenting the school enrollment is straightforward and powerful. The exception is high school seniors who finish their last year in the former state, which is generally accepted as a reasonable exception.
Pets. New York actually asks about pets in residency audits. Move your pets to Texas. Register them with a Texas veterinarian. Schedule wellness visits in Texas. It sounds small but it’s part of the ‘items near and dear’ analysis. Pets are often where the audit catches inconsistencies in the taxpayer’s story.
Memberships and affiliations. Join Texas-based country clubs, gyms, churches, synagogues, mosques, professional associations. Resign from corresponding organizations in your former state if you have time-based memberships. Document the join dates and pay the dues from a Texas-based bank account. Social ties are weighted in residency analyses, and a clear pattern of new Texas affiliations and dropped former-state affiliations is helpful.
California, New York, and Illinois: how aggressive each state is
California’s Franchise Tax Board is the most aggressive state residency auditor in the country. The FTB has a dedicated residency audit unit, and the unit has been highly active in the post-2020 period as wealthy Californians moved out of state. The FTB’s strategy is to identify high-income filers who changed their filing pattern (filed as nonresident or part-year resident after years of full-year resident filings), pull supporting documentation, and challenge the residency change if the documentation is thin. California also has a long statute of limitations: four years for routine returns, longer if the FTB asserts fraud, and indefinite if no return was filed.
New York’s DTF is similarly aggressive, particularly for former New York City residents who moved to Florida or Texas during 2020-2022. New York audits often focus on the ‘permanent place of abode’ issue: keeping a Manhattan apartment after the alleged move is a major audit trigger. The DTF has won several high-profile audit cases against former residents who maintained New York apartments. New York’s statutory residency test (permanent place of abode plus 183 days) is the most rigid in the country, and the day count is enforced strictly.
Illinois’s Department of Revenue is less aggressive than California or New York but still pursues high-income former residents. Illinois uses a domicile-based test similar to California, and the state has been more active in recent years as it has dealt with budget pressures. Illinois doesn’t have the dedicated residency audit unit that California has, but the audits the state does run tend to be thorough.
Other states with aggressive former-resident audits include Massachusetts, Minnesota, and New Jersey. State residency audits have become more common across the board as more taxpayers relocate to no-income-tax states. The pattern is consistent: high earners with significant income events (business sales, RSU vests, deferred compensation, large capital gains) get the most scrutiny.
Source-state income: what your former state can still tax
Even after a clean residency change, your former state can continue to tax certain types of income that are sourced to that state. The most important categories: deferred compensation paid for services performed while a resident, RSU and option income vesting after the move but earned for service during residency, capital gains on real property located in the former state, business income from operations within the former state, and rental income from former-state real estate. These don’t go away just because you moved.
Deferred compensation is the most contentious. A nonqualified deferred compensation plan that pays out over 10 years after retirement can be sourced to multiple states. If the executive earned the deferred comp while a California resident and now lives in Texas, California’s position is that California has the right to tax the deferred comp because the services were performed in California. The IRS and federal law (specifically the Pension Source Tax Act of 1996) limit states’ ability to tax deferred comp paid in substantially equal installments over 10+ years to former residents, but other forms of deferred comp may still be taxable by the former state.
RSU sourcing is where most clients are surprised. The general rule is that RSU income is allocated to the states where the recipient performed services during the vesting period. So a four-year RSU grant issued while a California resident, with vesting in years 1-4 of the grant, would be sourced as follows: each year’s vest is allocated based on where the recipient worked during the year prior to vest. If the recipient moves to Texas after year 2, the year 3 vest is partially California-source (the months between grant and the year-2 anniversary, while California-resident) and partially Texas-source (the months after the move). The year 4 vest is mostly Texas-source. California gets a smaller piece each year as the move ages.
Capital gains on property sold while still a former-state resident are entirely sourced to the former state. So if you own a California home, move to Texas, and then sell the California home a year later, the gain on the sale is California-source (real property is sourced to its location regardless of the seller’s residency). If you sell the California home before establishing Texas residency, the gain is entirely California-source. If you wait until after the move, the gain is still entirely California-source because of the real property rule. The move doesn’t change the sourcing for real estate. It only changes the sourcing for personal income.
Business income from operations in the former state is sourced based on where the activities occurred. If you own a California-based business and you move to Texas, the income from the California business is California-source income to the extent of California activities. Moving doesn’t change this. To eliminate the California tax on the business income, you’d need to either sell the business or genuinely move the operations to Texas (which is a much bigger undertaking than personal relocation).
Rental income from former-state real property is sourced to the location of the property. If you own a New York rental property and move to Texas, the New York property continues to generate New York-source income that must be reported on a New York nonresident return. This is straightforward sourcing and doesn’t change with the move.
Real-world example: A senior executive at a California tech company has $5M of RSUs vesting over four years. He moves to Texas after year 2. Year 1 vest ($1.25M): 100% California-source, $165,000 of California tax. Year 2 vest: 100% California-source, $165,000 of California tax. Year 3 vest: vesting period is months 25-36 of the grant. He moves at month 24 (start of year 3). So year 3 vest is 100% Texas-source, zero California tax. Year 4 vest: 100% Texas-source, zero California tax. Total California tax on the $5M of RSU income: $330,000. If he hadn’t moved, total California tax would have been $660,000. The move saved $330,000 on the RSU side alone, but California still got the year 1 and year 2 vests.
Alternative scenario: same executive, but he moves to Texas after year 1. Now year 2 vest is partially California-source (the months between vest 1 and the move) and partially Texas-source. Each subsequent vest has more Texas allocation. The earlier the move, the more savings. We work with clients on timing the move around vest schedules to make the most of the Texas-source allocation.
Audit triggers and how to think about risk
Certain events make a residency audit more likely. A change in filing status from resident to nonresident or part-year resident is the biggest signal. A large income event in the year of the move (RSU vest, business sale, IPO, large capital gain) attracts attention. A sudden drop in W-2 income reported to the former state. Continued ownership of a former-state home, especially in a desirable location. Continued business or professional activity in the former state. A spouse or children remaining in the former state. Filing a federal return showing the former state’s ZIP code or address.
The audit risk is highest in the year of the move and the immediate years after, particularly if there’s a large income event in those years. Risk diminishes over time but doesn’t disappear. We’ve seen audits open as much as five or six years after the move, especially if the taxpayer maintains some former-state ties and has a delayed income event (like deferred comp payments starting after retirement).
How to think about risk management. First, do the documentation. The factors discussed earlier are the audit defense. Second, sever ties cleanly. Sell the former-state home if you can. If you can’t, rent it out at arm’s length. Move the family. Change all the listed factors. Third, time the move. If you have a known income event coming (RSU cliff vest, IPO, business sale), plan the move to occur before the event with enough lead time that the residency change is genuine. A move three weeks before an IPO will not survive an audit. A move 14 months before with full documentation will. Fourth, file correctly. The partial-year return in the move year is more complex than people expect; the allocation between states requires careful calculation, and errors invite further audit attention.
The cost of getting it wrong. If a residency change fails on audit, the former state assesses tax on the full year (or the disputed portion), plus interest from the original filing date, plus penalties (which can be 20-50% of the tax depending on the state and circumstances). For a high earner with a $1M income event, a failed residency change can mean $130,000-$200,000 of back tax plus another $30,000-$80,000 of penalties and interest. Plus the cost of defending the audit, which for a contested case can run $50,000-$150,000 in professional fees.
What we do for clients on the move
Our process for clients relocating from California or New York to Texas starts before the move. We run the residency planning analysis: which factors need to change, what the timing should be, how to handle the former-state property, and how to coordinate with any pending income events. We also run the multi-state tax projection for the year of the move and the immediate years after, so the client knows what the partial-year and continuing former-state tax exposure looks like.
During the move, we coordinate the documentation. Driver’s license change, voter registration, vehicle registration, primary banking, professional advisors, school enrollment if applicable, club memberships. We maintain a file of the source documents (receipts, registration confirmations, voter cards, etc.) that’s audit-ready from day one. We also run the address-change protocol for federal accounts (IRS address, Social Security, brokerage accounts, retirement accounts) so the federal trail is consistent.
After the move, we file the partial-year returns correctly. We allocate income between states based on the actual sourcing rules (not rough estimates), and we maintain the documentation supporting the allocation. For clients with deferred compensation or RSU exposure to the former state, we file the nonresident returns for as long as the sourcing requires. We also coordinate with the client’s employer (if relevant) on withholding for the move year and subsequent years, to minimize over-withholding and refund delays.
If the audit comes, we defend. We’ve handled California FTB residency audits and New York DTF audits and the win rate depends overwhelmingly on the strength of the documentation. Clients who came to us before the move and built the file as they went tend to win or settle favorably. Clients who came to us after the audit notice arrived with thin documentation have a harder time. The audit defense is much cheaper than rebuilding evidence after the fact.

Frequently Asked Questions
I moved to Texas, so do I still file a state resident income tax return anywhere?
Texas has no state income tax. There is no Texas resident income tax return to file, no state line to fill out, no annual filing where you report your wages to Austin. That part is real, and it is one of the biggest reasons people pack up and move from California to Texas in the first place. But here is the trap that catches movers every year. The question that actually decides your state tax bill is not whether Texas taxes you. The question is whether the state you left still treats you as its resident. If California still considers you a California resident, California taxes your worldwide income no matter where you physically sleep at night, and the fact that you now live in Dallas does nothing to stop it.
This surprises people because they assume moving across a state line is a clean break, the way it is when you change apartments. It is not. A state like California does not let you go just because you signed a lease in Texas. California keeps two separate hooks that can pull you back into its tax system, and you have to clear both of them. The first hook is domicile, which is your true fixed permanent home, the place you intend to return to when you are away. The second hook is statutory residency, which is keeping a permanent place to live in California plus spending more than 183 days there in the year. Either one is enough to keep you on the hook for a California resident return, and California enforces this aggressively through its Franchise Tax Board.
So the right way to think about it is this. Moving to Texas does not by itself end your California residency. It starts a question. Did you actually change your domicile to Texas, and did you stop spending so much time in California that the 183-day rule snares you again. If you handle the move sloppily, keep your California house, keep your California driver license, fly back constantly, and leave your family behind in California, the state can keep taxing you as a full resident for years after you think you left. People in that situation often end up filing a California nonresident return for California-source income while still fighting over whether they owe a full resident return, and that fight is the audit.
On the federal side, none of this changes. You still file a federal Form 1040 every year regardless of which state you live in, because federal tax does not care about state borders. Your wages, your investment income, your business income all flow onto that federal return the same way they always did. The publication that walks through who has to file and how income is reported is Publication 17, and it is worth a read if you want to understand the federal filing picture before you layer the state residency question on top. The federal return is the easy part. The state residency fight is where the money and the risk live.
The practical takeaway for a new Texas mover is to stop asking which Texas form you file and start asking whether you have truly cut ties with the state you left. If you moved mid-year, you almost certainly owe a part-year California return for the period before you left, plus a nonresident return for any California income you keep earning. If you kept a foot in California, you may owe far more than that. We sort out exactly which returns you actually owe through our individual tax return preparation service, and when the residency question is genuinely close, we build the documentation case before the Franchise Tax Board ever asks for it through our tax strategy consulting work. Getting this wrong is not a small mistake. A wrongly assumed clean break can mean a full California resident assessment on every dollar you earned in Texas.
What is the difference between domicile and the 183-day statutory residency test?
These are two completely separate tests, and a state like California can tax you as a resident under either one. People mix them up constantly, and the confusion costs them. Domicile is about intent and your true permanent home. Statutory residency is a mechanical day count combined with whether you kept a place to live. You can fail one and pass the other and still end up taxed as a California resident, so you have to understand both.
Domicile is your one true fixed permanent home, the place the law treats as your real base no matter how much you travel. Everyone has exactly one domicile at a time, and you keep your old domicile until you actually establish a new one. That second part trips people up. You do not lose California domicile just by leaving. You lose it only when you genuinely plant your life in Texas and intend to stay. The Franchise Tax Board looks at a list of factors to decide where your domicile really sits. Where is the home you treat as your main residence. Where does your family live, your spouse and your kids. Where do you actually spend your time during the year. Where is your driver license issued. Where are you registered to vote. Where are your professional ties, your doctor, your dentist, your bank, your church or temple, your gym, your social life. And a factor that sounds odd but carries real weight, where do you keep your most treasured belongings, the heirlooms and items you would never leave behind in a place you were planning to abandon. If your family stays in California, your kids stay in California schools, your most prized possessions stay in the California house, and you keep voting in California, the state will argue your domicile never left, and they will often be right.
Statutory residency is a different animal entirely, and it does not care about your intent at all. The test has two parts that both have to be true. First, you keep a permanent place of abode in California, meaning a home available to you for the whole year, not a hotel room or a brief stay. Second, you spend more than 183 days physically present in California during the tax year. Cross both of those and California taxes you as a full resident even if your real domicile is genuinely in Texas. This is the test that catches the person who moved to Texas on paper, changed their license, registered to vote in Texas, did everything right on the domicile side, and then kept the California beach house and flew back so often that they were standing on California soil for 184 days. Intent did not save them. The day count did them in.
The 183-day count is literal and California counts days carefully. Any part of a day you are physically present in California generally counts as a full day there. Land at LAX at 11 at night and that is a California day. The state can pull your credit card records, your phone location data, your flight records, and your toll transponder history to reconstruct where you actually were. This is why a day-count log matters so much, which is its own subject. The point here is that the 183-day rule is a hard mathematical line, while domicile is a softer judgment about where your life is centered.
Put the two together and you see why a clean Texas move requires winning on both fronts. You have to move your domicile, which means moving the center of your life to Texas, family and license and voter registration and treasured belongings included. And you have to watch your day count, which means keeping your California days well under 183 if you still own a place there. Win the domicile argument but blow the day count and you are a statutory resident. Win the day count but leave your whole life in California and you are still domiciled there. We map both tests against a client’s real facts before they ever get a notice, and we structure the move so neither hook catches them, working through the planning side of our tax strategy consulting service. The federal income items that California would tax under either test still get reported the normal way on your Form 1040, with the rules in Publication 17 governing how that federal income is built before any state ever touches it.
Can California still tax me if I kept my house there and spent a lot of time in California?
Yes, and this is the most common way a Texas move falls apart. You keep the California house because you love it, or you have not sold it yet, or the kids are still finishing the school year there. Then you fly back often enough that your California days pile up. Hold onto a California home and spend more than 183 days in the state, and California can keep taxing you as a full resident even after you have told everyone you moved to Texas. The house plus the days is exactly the combination that triggers statutory residency.
Think about how easy it is to cross 183 days without meaning to. You moved to Texas in February, but you still own the Los Angeles house. You fly back for two weeks every month to see family, to check on the property, to keep your old business relationships warm. That is roughly 14 days a month, which over the remaining ten months of the year is 140 days, and that is before you add holidays, weddings, a sick parent, or a work project that drags you back. Stack a few of those on and you sail past 184 days without ever feeling like you live in California anymore. You feel like a Texan who visits a lot. California feels like you are a resident who took a trip to Texas. And because you kept the house, the permanent place of abode requirement is already satisfied, so the only open question is the day count, and the day count went against you.
The keeping the house factor does double duty against you. It satisfies the abode half of the statutory residency test, and it also weighs heavily on the domicile side, because a home you keep, furnish, and use looks a lot like the home of someone who never really left. If that California house is bigger, nicer, and more lived in than your Texas place, the Franchise Tax Board will argue your Texas address is the secondary home and California is still your real base. Auditors compare the two properties directly. Square footage, where your furniture is, where your mail goes, which utility bills show steady usage, which address your important accounts list. A Texas apartment you barely sleep in does not beat a California house you spend half the year in.
There is a hard truth here about wanting it both ways. A lot of people want the Texas tax result without giving up the California lifestyle. They want zero state income tax and the beach house and the California friends and the constant flights back. California built the statutory residency rule precisely to stop that arrangement. If you are going to keep the California home, you have to be disciplined and ruthless about your day count, because the home alone is enough to make the days the only thing standing between you and a full resident assessment. The cleaner play, if you can manage it, is to sell or genuinely give up the California home, which removes the abode prong entirely and makes the statutory residency test impossible for California to win.
If you are determined to keep the house, the planning becomes a day-management exercise. Track every California day in real time, not at year-end. Keep the count with a wide margin under 183, because the state resolves close calls in its own favor and you do not want to be arguing about whether a travel day counts when you are sitting at 182. Document where you were on the borderline days. We help clients who refuse to sell the old house build a defensible day-tracking system and decide how many California days they can actually afford, as part of our tax strategy consulting service. When the year is done, we prepare the returns that the facts actually support, whether that is a clean nonresident return or a part-year return, through our individual tax return preparation service. The income still reports federally on Form 1040 the same way, but whether California gets to tax all of it or none of it comes down to that house and those days.
How do I defend a Franchise Tax Board residency audit after moving to Texas?
You defend a residency audit with documentation, and you build that documentation before the audit ever starts, not after the notice arrives. The Franchise Tax Board runs residency audits on people who claim they left high-tax California for a no-tax state like Texas, because that claim costs California a lot of money and the state checks it hard. The audit comes down to two questions. Did you really change your domicile, and did you stay under 183 California days. Your job is to have proof ready for both before the auditor asks.
The single most powerful piece of evidence is a contemporaneous day-count log. This is a running record, kept throughout the year as it happens, of where you were physically located each day. Not a reconstruction you cobble together when the audit letter shows up, because auditors discount after-the-fact reconstructions and trust real-time records. Back the log with hard evidence the state cannot wave away. Flight itineraries and boarding passes. Credit card and debit card charges that put you in a specific city on a specific date. Phone location history. Toll transponder records. Hotel receipts. The log says where you were, and the receipts prove it. If you kept the California house and the day count is what protects you, this log is the whole ballgame.
On the domicile side, you defend by showing you actually moved the center of your life to Texas, and the proof is the same set of factors the state uses to decide domicile, turned into a paper trail. Get a Texas homestead, meaning a Texas home you treat as your primary residence and ideally claim the Texas homestead exemption on, because that exemption is a formal declaration to a government that this is your main home. Get a Texas driver license and surrender the California one. Register your vehicles in Texas. Register to vote in Texas and actually vote there. Move your most treasured belongings to the Texas home, the things you would never store in a place you were leaving. Move your family if you can, because a spouse and children still living in California is the single fact that sinks the most domicile cases. Change your doctors, your dentist, your bank, your church or temple, your gym, your professional memberships, your mailing address, your estate planning documents. Each one is a small fact. Together they paint a picture of a life that genuinely relocated.
The other half of the domicile case is cutting California ties, and this matters as much as building Texas ties. The Franchise Tax Board does not just look at what you started in Texas. It looks at what you kept in California. Resign from California club memberships and boards. Close or move California-based accounts where practical. Stop using a California mailing address. If you kept the California house, be ready to explain why in a way that does not sound like you never left, such as it being held for sale or rented to a tenant rather than kept ready for your own use. A California house sitting furnished and available for you to walk into any weekend is a domicile problem. The same house leased to an unrelated tenant for the year is far easier to defend.
When the audit actually lands, respond carefully and do not freelance. The Franchise Tax Board will send a residency questionnaire asking about your homes, your days, your family, your licenses, your ties. Every answer has to line up with your documentation, because inconsistencies are what auditors pounce on. This is not the moment to handle it alone, and you should not let the state frame the narrative. We represent clients through California residency audits and assemble the day-count log, the homestead and license and registration proof, and the cut-ties evidence into one organized package, working through our tax strategy consulting service. We also keep the underlying records straight all year, because clean books and a clean paper trail are what win these cases, which is part of what our bookkeeping work supports. The federal return on Form 1040 runs the same regardless, but the state assessment hanging on the audit can be the difference between owing California nothing and owing California tax on your entire worldwide income.
Does Texas residency protect me from tax on income I still earn in California?
No. This is where even people who nail the residency move get a nasty surprise. Becoming a Texas resident, even a clean one who clears both the domicile test and the 183-day test, does nothing to shield income that has its source in California. California taxes nonresidents on California-source income, period. So you can be a genuine Texan, owe no California resident tax, and still owe California a nonresident return on certain income because of where that income came from. Texas residency protects your Texas-source and other-state income. It does not protect anything California can point to and call its own.
The two big categories of California-source income that follow you no matter where you live are California real estate and California-earned compensation. Start with real estate. If you own a rental property in California, the rent is California-source income and California taxes it whether you live in San Antonio or Singapore. When you sell that California property, the gain is California-source and California taxes the gain, again regardless of your residency. The land does not move, so the income from it stays sourced to California forever. A Texas mover who keeps a California rental as an investment has not escaped California tax on that property. They have just changed which return reports it, from a resident return covering everything to a nonresident return covering the California piece.
California-earned compensation is the other one, and it is broader than people expect. Wages for work physically performed in California are California-source even if you are paid by a Texas employer into a Texas bank account. If you fly back to California and work there for a stretch, the pay for those days is California-source. Compensation that was earned while you were a California resident but paid out later, such as deferred compensation, stock that vested over a period that included California service, or a bonus tied to past California work, can carry California source even after you move. The general principle is that California sources compensation to where the work was done, not where you lived when the check cleared. Sell company stock you earned grinding away in a California office before your move, and California may want a piece of the gain attributable to the California vesting period.
This means a Texas mover often files two things. No California resident return, because residency genuinely moved to Texas. But a California nonresident return for the California-source slice, the rental income, the gain on California property, the compensation earned for California work. Getting the sourcing right on that nonresident return is its own careful job. Capital gains on the sale of California real estate run through the federal capital gains machinery first, reported on Form 8949 and summarized on Schedule D of your federal return, and California then taxes the California-source portion on the nonresident side. The sourcing rules decide how much California gets, and they are not always obvious, especially for compensation that straddled your move date.
One more practical point. Because California can still reach this income, you may owe California estimated tax on it as a nonresident, which means quarterly payments tracked alongside your federal estimates on Form 1040-ES. People who think Texas residency zeroed out their California obligation skip those payments and then eat penalties on the California-source income they forgot was still taxable. The cleanest version of a Texas move sheds the California-source income entirely, by selling the California rental and not going back to perform California work, so there is nothing left for California to tax. When that is not possible or not what you want, the answer is to report the California-source income correctly on a nonresident return rather than pretend it disappeared. We handle that split, the federal return plus the California nonresident return for the sourced income, through our individual tax return preparation service, and we plan the timing of property sales and equity compensation around the move date so California captures as little as the law allows through our tax strategy consulting work.
