Remote Work and Multi-State Taxes: What You Need to Know

The short answer is that your home state almost always gets first crack at taxing your income. If you live in New Jersey and work from your kitchen table for a company based in Texas, New Jersey taxes that income because you physically earned it there. Texas has no state income tax, so you are not dealing with a second state in that scenario. Simple enough. But most remote workers are not in that simple scenario, and the complications start piling up fast once you add a second state to the picture.

The biggest wrinkle is something called the “convenience of the employer” rule. New York is the most aggressive state on this front. Under New York’s version, if your employer has an office in Manhattan and you work remotely from your home in Connecticut or New Jersey, New York still claims the right to tax your wages. The theory is that you are working from home for your own convenience, not because the employer required it. Unless you can show that the employer specifically mandated the remote arrangement — maybe your role has no available desk in the New York office, or the job description explicitly says “remote only” — New York will treat your wages as New York-source income and expect you to pay New York state tax on them.

Connecticut, Pennsylvania and Delaware have similar rules, though each state phrases it a little differently and enforces it with varying levels of aggression. Pennsylvania’s version is narrower and mainly applies when you are assigned to a Pennsylvania office but choose to work from somewhere else. Connecticut enacted its own version partly in response to New York taxing Connecticut residents who worked from home during the pandemic — Connecticut was losing revenue to New York’s rule and decided to fight fire with fire. Delaware’s rule is less commonly enforced but exists on the books, and it can surprise people who work for companies headquartered in Wilmington.

Here is where it gets expensive in real dollar terms. If New York taxes your wages under the convenience rule, your home state (say, New Jersey) also taxes those same wages because you physically worked there. You end up with two states claiming the same income. New Jersey will give you a credit for taxes paid to New York on Form NJ-1040, but only up to the amount New Jersey would have charged on that income. If New York’s effective rate is higher than New Jersey’s, you eat the difference. For someone earning $200,000, that gap can mean $2,000 to $4,000 in extra tax per year that just disappears into the system with no recovery mechanism. Over five years of remote work, that is $10,000 to $20,000 in tax you would not owe if you physically commuted to the New York office.

States without a convenience rule generally follow what is called the physical presence standard. You owe tax in the state where your body was when you did the work, and nowhere else. If you spent three weeks working from a rental in Colorado and the rest of the year in your home state of Georgia, Colorado could technically tax those three weeks of income. Whether Colorado actually comes after you for that amount depends on their filing thresholds — most states have a minimum number of days or dollars before they require a nonresident return. Some states set the bar at 15 days, others at 30, and a few (like New York and California) have effectively no minimum at all. California will chase you for income earned during a single day of work in the state if the numbers are big enough.

If your employer is in a no-income-tax state like Florida, Texas, Nevada, Washington, Wyoming, South Dakota, or Tennessee, you typically only owe tax in your home state. That is the simplest remote work tax scenario. Your W-2 shows withholding for your home state, you file one state return, and you are done. New Hampshire also has no broad-based income tax, though it did tax interest and dividend income above $2,400 ($4,800 for joint filers) through the end of 2024 — that tax was fully phased out starting in 2025. Alaska has no state income tax either, but some Alaska municipalities levy local income taxes, so even a “no income tax” state is not always zero.

For freelancers and independent contractors, the rules shift. You generally owe tax to your home state on all your income. But you may also owe tax in any state where you have enough of a business presence — called “nexus” — to trigger a filing obligation. Having a single client in another state does not usually create nexus by itself, but it depends on the state and the nature of the work. If you travel to a client’s location to perform services, those days are almost certainly taxable in the client’s state. And some states define nexus broadly enough that regularly performing services for customers located there can create an obligation even if you never visit.

One thing people miss: state and local taxes interact, too. If you live in New York City and work remotely for a company in another state, you still owe NYC resident income tax on all your income regardless of where the work is performed. The city tax rate tops out at 3.876%, and that is on top of New York State’s rates which go up to 10.9% for high earners. Yonkers has its own resident income tax surcharge of 16.75% of your state tax liability, which is a different calculation but still a meaningful addition. These local taxes do not care where your employer is — they care where you live.

The bottom line: figure out where your employer is based, whether that state has a convenience rule, and whether your home state offers a full credit for taxes paid to the other state. If you are in a situation where two states are taxing the same income and the credits do not fully offset, a tax professional can map out the numbers and determine whether restructuring the arrangement — maybe getting the employer to formally designate the role as required-remote — would save you money. We handle these multi-state situations regularly at The Reed Corporation for clients who live and work across New York, New Jersey, and Connecticut.

Yes, and this catches a lot of people off guard. If your employer is headquartered in a state with a convenience-of-the-employer doctrine, that state can tax your wages even if you have never physically entered their office building. New York is the most aggressive state on this front, and its rule affects tens of thousands of remote workers across the tri-state area and beyond. The basic premise is counterintuitive to most people: a state where you have never worked can still tax your work income.

The way New York’s rule works is straightforward in concept but painful in practice. If your employer maintains an office in New York and you could theoretically work from that office but choose not to, New York considers your remote work to be for your personal convenience. Because the work could have been done in New York, New York treats the income as if it were earned there. The burden falls on you — the employee, not the employer — to prove otherwise. Specifically, you need to show that the employer required you to work remotely, that the remote location serves a genuine business purpose (not just saving you a commute or giving you a better quality of life), and that the employer does not have available workspace for you in their New York office.

The documentation requirements are strict, and New York auditors know what to look for. During audits, the Department of Taxation and Finance examines evidence like a formal remote work policy from the employer stating that the position must be performed remotely, proof that no office space was assigned or available for the employee in New York, written correspondence showing the employer directed the remote arrangement for business reasons, and records demonstrating that the employer recruited the employee specifically because of their location outside New York. If you just have a casual verbal agreement where your manager said “sure, work from home if you want,” that is not going to hold up in an audit. New York’s auditors have seen every version of this argument and they are not easily convinced.

Other states with similar provisions include Connecticut, which enacted its own convenience rule partly as a defensive revenue measure after New York started taxing Connecticut residents who worked from home. Pennsylvania has a version, though it is narrower in scope — it mainly targets people who are assigned to a Pennsylvania office but choose to work from another state by preference. Nebraska adopted a similar provision in 2003 that applies to employees of Nebraska-based employers. Delaware also has convenience-style rules, which primarily affect employees of the many corporations chartered there.

The financial impact is not trivial. Say you earn $150,000 and live in New Jersey while working remotely for a company with its main office in Manhattan. New York State’s marginal rate on that income level is around 6.85%. If the employer is specifically a New York City company and New York argues you would have worked in the city, New York City’s additional income tax of up to 3.876% could also apply — though the application of city tax to convenience-rule workers is a separate and somewhat contested issue. New Jersey will give you a resident credit on your NJ-1040 for the New York tax, but the combined New York rate often exceeds New Jersey’s rate on the same income. The excess — potentially $3,000 to $5,000 per year on $150,000 of income — comes straight out of your pocket with no offsetting credit anywhere. That is real money disappearing into a gap between two states’ tax systems.

There have been legal challenges, and so far the results have not favored taxpayers. New Hampshire filed an original jurisdiction lawsuit with the U.S. Supreme Court in 2020 challenging Massachusetts’s convenience-style rule that was imposed during the COVID pandemic. The Court declined to hear the case in June 2022, which many tax professionals interpreted as a signal that the Court does not view cross-border taxation of remote workers as a constitutional issue requiring its intervention. Several states have pushed back through legislation instead. Connecticut passed a law allowing its residents to claim a credit against Connecticut tax for taxes paid to other states under convenience rules, which effectively shifts the economic cost back to Connecticut’s treasury rather than leaving it with the individual taxpayer. But not every state has taken that protective step.

From a practical standpoint, if you are in this situation, there are several things worth exploring with a professional. First, ask your employer whether they are willing to formally classify your position as a remote role required by the business rather than offered as a perk. If the employer documents in writing that the role must be remote — maybe the team is fully distributed, maybe they specifically recruited you from another state, maybe there is genuinely no available workspace in the New York office — that documentation weakens New York’s convenience argument. Second, track your work days by location with precision. If you do visit the New York office occasionally — say, for quarterly meetings — those days are definitely New York-source income regardless of any convenience rule. But the days you work from home may be defensible if the employer documentation supports a necessity argument.

Third, run the actual numbers. Sometimes the tax cost of the convenience rule is smaller than people expect once credits are properly applied, and it may not justify the effort and expense of fighting it. Other times the cost is significant enough to warrant restructuring — the employer might set up a satellite office registration in your home state, which can change the analysis entirely. We work with a number of clients at The Reed Corporation who face this exact issue, usually because they live in New Jersey or Connecticut and work for a New York-based employer. The analysis is specific to each situation, but the savings from getting the classification right can run into thousands of dollars per year, especially for higher earners where the rate differential between states compounds significantly.

Technically, yes — if a state considers you to have earned income within its borders, you have a filing obligation there. But “technically” and “practically” are two very different things in state taxation, and whether you actually need to file depends on how long you worked in each state, how much you earned there, and whether the state has a minimum threshold before it requires you to file a nonresident return.

Most states do set some kind of filing threshold for nonresidents, but the thresholds vary enormously. New York requires a nonresident return (Form IT-203) if you earned any income in the state — there is no minimum dollar amount and no minimum number of days. One day of work in New York at a high enough income level can trigger a filing requirement. California is similarly aggressive: any California-source income requires a nonresident return, and California’s Franchise Tax Board is one of the most active state revenue agencies in the country for tracking down nonresident filers. Other states are more practical about it. Some set dollar thresholds — if you earned less than $600 or $1,000 in the state, no return is required. A few use day-count thresholds: if you worked fewer than a certain number of days in the state, you may be exempt from filing. Illinois exempts nonresidents who work in the state for 30 days or fewer, for example.

The “digital nomad” scenario is where things get especially messy from a compliance standpoint. Say you spent January and February working from a friend’s apartment in Colorado, March and April at your parents’ place in Florida, May through July at an Airbnb in North Carolina, and the rest of the year at home in New York. Florida has no income tax, so that leg of the trip is a non-issue. But Colorado taxes nonresidents on income earned while physically present in the state. North Carolina does the same. You would technically owe a nonresident return in both Colorado and North Carolina for the income attributable to the months you spent working there. New York would also tax all of your income as your state of residence.

The income allocation for nonresident returns is usually based on a day count. You take your total annual income, divide by the number of working days in the year (usually around 250 to 260), and multiply by the number of days you worked in the nonresident state. If you earned $180,000 for the year and worked 40 days in Colorado, Colorado’s share would be roughly $180,000 times 40 divided by 260, which is about $27,692. Colorado’s income tax rate is a flat 4.4%, so you would owe approximately $1,219 to Colorado. Your home state should give you a credit for that amount on your resident return, so in theory you are not paying double tax — but the paperwork and filing fees for each additional state return add friction and cost.

Is Colorado likely to come after you for two months of remote work income if you are a W-2 employee? That depends on the paper trail. If your employer did not withhold Colorado taxes, there is no automatic flag in Colorado’s system connecting your income to the state. But if you are self-employed and your business has any connection to Colorado — a client there, a business registration, a mailing address — the risk of detection goes up. And if you bought property, registered a vehicle, obtained a driver’s license, or took other actions that create a record in Colorado, the state has more tools to identify you as someone who may owe taxes.

Some states have adopted specific de minimis exemptions for remote and traveling workers, and these are the closest thing to a rational system that exists right now. A handful of states exempt nonresidents who work in the state for fewer than 30 days per year. Others set the threshold at 15 days, 14 days, or even 7 days. The Mobile Workforce State Income Tax Simplification Act — a bill that has been introduced in Congress multiple times — would establish a uniform 30-day threshold nationally: if you work in a state for fewer than 30 days, that state cannot tax your wages. The bill has bipartisan support and the backing of the American Institute of CPAs and the Council on State Taxation, but as of early 2026, it has not passed. So you are stuck working through a patchwork of different state rules with no federal floor.

Here is what we recommend to clients who travel and work across multiple states during the year. First, keep a detailed calendar or log of where you worked each day. This does not have to be fancy — a spreadsheet or even a calendar app with location tags works fine. The important thing is that you have contemporaneous records (created at the time, not reconstructed later) showing your physical location on each workday. Second, check the filing thresholds for each state where you spent time working. Each state’s Department of Revenue website lists nonresident filing requirements, and the Federation of Tax Administrators maintains a central directory linking to all 50 states. Third, prioritize accuracy over minimizing the number of returns. Filing a nonresident return in a state where you owe $200 is cheap insurance. Getting caught not filing — even for a small amount — can trigger penalties (typically 5% per month up to 25% of the tax owed), interest (usually running at 7% to 12% annually depending on the state), and a much more expensive cleanup process that involves amended returns, penalty abatement requests, and professional fees.

For W-2 employees, your employer’s payroll department should be withholding taxes for any state where you regularly work. If they are not — say you moved to a new state mid-year and nobody updated the withholding setup — you may need to make estimated tax payments directly to the new state to avoid underpayment penalties. Talk to your employer’s HR or payroll team and confirm they know where you are actually working. Employers have their own compliance obligations when employees work from different states, and they generally want to get the withholding right because the penalties for getting it wrong fall on them too.

At The Reed Corporation, we file multi-state returns regularly for clients who work remotely, travel for business, or split time between states. The goal is always to file where required, claim every available credit to prevent double taxation, and make sure you are not paying more than you actually owe to any single state.

COVID forced a massive temporary experiment in remote work taxation, and the results have been mixed. Some changes stuck, others were rolled back, and the overall landscape is more contested than it was before the pandemic started. During 2020 and 2021, many states issued emergency guidance suspending their normal sourcing rules for remote workers. The logic was simple: millions of people suddenly working from home should not face unexpected tax bills in states they had no connection to before March 2020. But those emergency provisions came with expiration dates, and most have since lapsed.

Most states reverted to their pre-COVID rules by the end of 2021 or early 2022. New York’s convenience-of-the-employer doctrine, for example, never really went away during the pandemic. New York took the position that even pandemic-forced remote work was for the employee’s convenience, not the employer’s necessity, unless the employer’s New York office was literally closed by government order and physically inaccessible. Once offices reopened — even partially — New York resumed its aggressive stance that employees who chose to continue working remotely were doing so by personal preference. This generated significant controversy and media attention, but New York did not budge.

Several states fought back through the courts. New Hampshire filed an original jurisdiction case with the U.S. Supreme Court in October 2020, challenging Massachusetts’s rule that continued to tax New Hampshire residents who had previously commuted to Massachusetts but were now working from home. The argument was that Massachusetts was taxing income earned entirely within New Hampshire’s borders, which violated the Commerce Clause and Due Process Clause of the Constitution. The Supreme Court declined to hear the case in June 2022 without explaining its reasoning. Tax lawyers widely viewed this as a disappointing outcome, because it left states free to continue taxing remote workers under convenience-style rules without any constitutional guardrail.

What did change permanently is the scale and visibility of remote work itself. Before COVID, the convenience-of-the-employer doctrine affected a relatively small group — mostly high-earning professionals in finance and tech who chose to live in Connecticut or New Jersey while working for Manhattan-based firms. After COVID, remote and hybrid work became mainstream across industries, income levels, and geographies. That means the same old tax rules now affect orders of magnitude more people, which has increased political pressure on states to update their approach. Governors, state legislators, and tax policy organizations are all paying attention to this issue in ways they were not before 2020.

Several states have responded with new legislation since the pandemic. Connecticut passed a law giving its residents a credit for taxes paid to other states under convenience rules, which specifically targets the New York situation. The credit does not eliminate the problem — it shifts the cost from the individual taxpayer to Connecticut’s state budget — but it means Connecticut residents are no longer personally out of pocket for the New York convenience tax. New Jersey has been lobbying for a similar solution, both at the state level and through congressional advocacy for a federal fix.

On the federal front, a bipartisan group in Congress introduced the Remote and Mobile Worker Relief Act in 2023, which would establish a 30-day threshold: if you work in a state for fewer than 30 days in a calendar year, that state cannot impose income tax on your wages earned during those days. The bill has support from business groups, payroll companies, and accounting organizations, but it has not passed as of early 2026. Previous versions of similar legislation have been introduced as far back as 2012 without success, so the track record is not encouraging, though the post-COVID political climate gives this version better odds than its predecessors.

Some states took the pandemic as an opportunity to actively recruit remote workers. States with no income tax — Florida, Texas, Tennessee — saw significant inflows of remote workers relocating from high-tax states like New York and New Jersey. The trend was particularly pronounced among tech workers and financial services professionals who could do their jobs from anywhere and saw a chance to cut their state tax bills to zero. Other states created specific incentive programs. West Virginia’s Ascend WV program offered $12,000 in cash (plus free outdoor recreation passes) to remote workers who relocated there. Maine and Vermont offered similar programs with smaller dollar amounts. Some of these programs are still active, though funding comes and goes.

The practical effect for most remote workers in 2025 and 2026 is that the pre-COVID tax rules are back in force, but three things have changed in meaningful ways. First, awareness is much higher. More employees are asking about state tax implications before accepting remote positions, and more employers have multi-state payroll systems in place. Second, enforcement is getting tighter. States are investing in data-sharing agreements and automated systems to identify nonresident filers, and they are auditing remote work arrangements more aggressively than before the pandemic. Third, employer policies have hardened. Many companies now restrict remote work to approved states where they are already registered for payroll and income tax purposes. If your employer tells you that you can only work remotely from certain states, their tax and legal compliance team almost certainly drove that decision.

For employees who relocated during COVID and stayed in the new state, the transition years of 2020 and 2021 may have created a complex tax situation that is still unresolved. If you moved from New York to Florida in March 2020, New York might argue you remained a statutory resident for the full year if you kept a home in New York — even an empty apartment with an active lease counts. Sorting out domicile and statutory residency for those transition years sometimes requires professional help, especially if the amounts involved are large enough to attract audit attention. We handle these exact situations at The Reed Corporation, particularly for clients who split time between New York and tax-free states like Florida and Texas, where the domicile analysis can get particularly complicated when you maintain connections to both states.

It absolutely can, and this is an angle that a lot of remote employees never think about until it becomes a problem. When you work from a state where your employer does not have an office or business registration, you may be creating what tax law calls “nexus” for your employer in that state. Nexus is the legal connection between a business and a state that gives the state the right to impose taxes and regulatory requirements. Having even one employee physically working in a state can trigger income tax, franchise tax, sales tax, and payroll tax obligations for the employer — and the employer did not necessarily sign up for any of that when they agreed to let you work from home.

Start with payroll taxes, because those are the most immediate and unavoidable obligation. If you work remotely from a state where your employer is not registered, your employer technically needs to register with that state’s Department of Revenue and Department of Labor, set up state income tax withholding from your paycheck, file quarterly payroll tax returns with the state, and pay employer-side taxes like state unemployment insurance (SUI). The SUI rates vary by state and by employer experience rating, but new employers in a state typically pay a higher “new employer” rate that can range from 1% to 4% or more of the first $7,000 to $45,000 of each employee’s wages, depending on the state. For a single remote employee, the administrative cost of getting all this set up — registration fees, payroll system configuration, quarterly filings — can easily run $2,000 to $5,000 per year before you even get to the actual tax payments.

Then there is state income tax nexus for the business itself. In most states, having an employee regularly working within the state’s borders creates income tax nexus for the employer’s business entity. That means the employer may need to file a corporate income tax return (or franchise tax return, or gross receipts tax return, depending on how that state structures its business taxes) and apportion some of its business income to your state based on the state’s apportionment formula. Most states use a single sales factor apportionment now, meaning your employer’s income is apportioned based on where its customers are, not where its employees are. But some states still include payroll and property in the formula, and having an employee in the state directly increases the payroll factor. For a large company with employees in 30 states, this is already part of normal operations and the incremental cost of adding one more state is modest. For a small business with 15 employees that has only ever filed in one or two states, your move to a new state can trigger thousands of dollars in new compliance costs and potentially new tax liability.

Sales tax nexus is another concern that gets overlooked. Under the Wayfair decision from 2018, states can require businesses to collect sales tax based on economic nexus — meaning a certain threshold of sales dollars or number of transactions in the state, regardless of physical presence. But physical presence, including having employees in a state, has always been an independent basis for sales tax nexus. If your employer sells products or taxable services and you are working from a state where they have not been collecting sales tax, your physical presence in that state could trigger a sales tax registration and collection obligation. Depending on how long you have been working there without the employer collecting, there could be retroactive liability for sales tax that should have been collected from customers but was not. That is the employer’s liability, not yours, but it is a liability your remote work created.

Some employers have dealt with this problem by restricting where employees can work remotely. If you have ever seen a job posting that says “remote, but must be based in one of the following 15 states,” that is almost always a tax and compliance decision, not a geographic preference. The company has already registered and set up payroll and tax compliance in those states and does not want to add new ones because each additional state means more registrations, more filings, more fees, and more audit exposure. Other employers use employer-of-record (EOR) services — third-party companies like Deel, Remote, or Papaya Global that technically employ the remote worker in the new state, handling all the registration and compliance on behalf of the original employer. The EOR charges a fee (usually $300 to $700 per employee per month), but it eliminates the compliance headache for the employer.

The risk for the employee is indirect but very real. If your employer discovers — maybe during a tax audit, or when hiring a new CFO, or when an outside accountant reviews the books — that your remote work has created unexpected nexus and compliance obligations in a state they never planned to operate in, the employer may decide the arrangement is not worth the cost. We have seen situations where employers ask remote workers to either relocate back to an approved state or return to the office because the multi-state tax burden became unmanageable. That is not a great position to be in if you have already bought a house, enrolled your kids in school, and built a life in your remote location.

International remote work adds an entirely different layer of complexity. If you work remotely from another country for a U.S. employer, your employer may inadvertently create a “permanent establishment” in that country under the applicable tax treaty (or under domestic law if there is no treaty). A permanent establishment can trigger corporate income tax obligations in the foreign country, VAT or GST registration and collection requirements, local employment law compliance (including mandatory benefits, notice periods, and termination protections), and social security contributions in the foreign country’s system. Most small and mid-size U.S. employers are simply not equipped to handle international employment compliance, which is why so many remote job postings say “U.S.-based candidates only.” Even a short stint working from abroad can create issues — France, for example, can assert permanent establishment status after just a few months of an employee working within its borders.

The best approach is transparency and planning. Before you start working remotely from a new state or country, have a conversation with your employer about the tax and compliance implications. If the employer does not know the answer — and many do not — suggest they consult with their accountant, tax advisor, or a payroll specialist who handles multi-state compliance. It is much easier and significantly cheaper to set things up correctly from the start than to unwind a multi-state or international compliance mess after the fact. And if you are a business owner with remote employees scattered across multiple states, we can help you understand your multi-state filing obligations and make sure you are properly registered everywhere you need to be.
