Austin freelancer tax guide: self-employment tax, Schedule SE, and the quarterly estimate trap

No. Texas does not have an individual state income tax. Austin freelancers pay federal income tax and federal self-employment tax (SECA) to the IRS, but nothing to the Texas Comptroller on the income side. This puts Texas freelancers in the same camp as freelancers in Florida, Tennessee, Nevada, Washington, South Dakota, Wyoming, and Alaska, all of which have no individual income tax.

Compare this to California, where a freelancer earning $150,000 of net profit would pay roughly $11,000 to $12,000 of California state income tax in addition to federal. New York would charge similar amounts at the state level, plus an additional 3.876% if the freelancer lives in New York City. Oregon’s top rate is 9.9%. These differences add up fast for high-earning freelancers. A San Francisco copywriter making $200,000 net pays approximately $20,000 to $22,000 of California tax that an Austin copywriter making the same amount does not owe.

What Texas does have is the franchise tax (margin tax), which applies to LLCs, corporations, and most other entities operating in Texas. A sole proprietor freelancer filing on a 1040 Schedule C is not subject to the franchise tax because the sole proprietorship is not a separate entity from the individual. But the moment you form an LLC (which we recommend for most serious freelancers for liability protection), the LLC becomes subject to franchise tax filing requirements.

The good news for most Austin freelancers is that the no-tax-due threshold is approximately $2.65 million in annual revenue for 2026. Any Texas LLC below that threshold owes zero franchise tax. But the LLC still has to file a No Tax Due Report each year with the Texas Comptroller. The deadline is May 15. Missing the filing triggers penalties and can put the LLC’s good-standing status at risk. We file the No Tax Due Report for every Austin LLC client we work with as part of annual compliance.

There’s also a Texas Public Information Report that LLCs must file annually with the same May 15 deadline. This filing lists the LLC’s managers, members, and registered agent. Like the franchise tax No Tax Due Report, this is a compliance filing rather than a tax payment, but missing it has real consequences. We handle both filings together as a single annual package.

Common mistake: freelancers who move from California or New York to Austin assume the state tax difference will show up immediately on their next federal return. It won’t, because federal tax is calculated separately and the state tax savings happen on the state return (or, in this case, the absence of a state return). The full benefit of the Texas move shows up on the state side, where the absence of any state tax liability is the entire story.

Real example. A graphic designer who moved from Brooklyn to East Austin in 2024 saw her after-tax income jump by roughly $14,000 on the same gross earnings just from the elimination of New York State and New York City income tax. Her federal liability stayed approximately the same. The rent in East Austin was about $800 less per month than Brooklyn, so she came out ahead by roughly $24,000 per year before any other expense changes.

Where freelancers do still owe state tax is on income earned while physically in another state. If you fly to California for two weeks of on-site client work, California can argue that the income from those two weeks is California-source income and tax it so. The threshold for triggering filing obligations varies by state, but most have some kind of de minimis rule. Texas residents who do occasional out-of-state work generally don’t trigger filing requirements in other states, but extended on-site engagements can. We review this case-by-case for any client doing significant out-of-state work.

Where we help: handling LLC formation in Texas, filing the annual franchise tax No Tax Due Report and Public Information Report, structuring multi-state engagements to minimize other states’ tax claims, advising freelancers relocating from high-tax states on the timing and documentation of the move, and preparing federal returns that properly reflect Texas residency. The state-tax advantage is real and substantial. Most Austin freelancers we work with don’t realize how much they’re saving relative to peers in California or New York until they see the comparison spelled out on a return.

The most-missed deduction by a wide margin is the home office. Many freelancers assume the home office deduction is an audit red flag and skip it entirely. That hasn’t been true for a long time. The IRS introduced a simplified method (5 dollars per square foot up to 300 square feet, max $1,500) specifically to reduce audit risk and encourage legitimate claims. The actual-expense method (deducting a percentage of rent, utilities, insurance, internet based on the percentage of the home used for business) usually produces a bigger deduction for Austin freelancers with significant rent.

The rules for the home office are strict but defensible. The space must be used regularly and exclusively for business. A bedroom that doubles as a guest room does not qualify. A dedicated office or even a corner of a room that’s used only for work does. The space must also be your principal place of business or a place where you regularly meet clients. For most freelancers, the home office qualifies as the principal place of business because that’s where the work actually happens.

Self-employed health insurance is the second most-missed. Premiums for medical, dental, and vision insurance that you pay personally (not through a spouse’s employer plan) are deductible above the line on Schedule 1. The deduction is limited to net self-employment earnings. Coverage for the freelancer’s spouse and dependents qualifies. ACA Marketplace plans qualify. Cobra continuation coverage from a former employer also qualifies as long as the freelancer is no longer eligible for coverage through a current employer (theirs or a spouse’s).

Retirement plan contributions are the third. A Solo 401(k) lets a self-employed person contribute up to $24,500 in employee deferrals ($31,000 if age 50+) plus roughly 20% of net self-employment earnings as the employer portion, all the way up to a $72,000 total combined limit for 2026. SEP-IRAs work similarly but without the deferral piece, which makes the SEP less efficient at lower income levels. We almost always recommend Solo 401(k) for Austin freelancer clients. The deferral contributions reduce both income tax and AGI, while the employer contributions reduce income tax. Neither reduces SE tax.

Vehicle expenses are missed when freelancers drive for business but don’t keep a mileage log. The IRS requires contemporaneous records (not reconstructed-after-the-fact records) showing date, business purpose, start and end odometer or mileage, and total business miles. Apps like MileIQ or Stride automate this. At 72.5 cents per mile through June 2026 and 76 cents from July 1, even 5,000 business miles produces roughly $3,700 in deductions. Most freelancers driving to client meetings, coworking spaces, supply pickups, or business events significantly understate their business mileage.

Software subscriptions and professional development. Adobe Creative Cloud at $60 per month is $720 per year. Figma, Notion, Slack, Zoom, GitHub, accounting software, project management tools, and industry-specific software all add up. Conference attendance, online courses, books, and trade publications that maintain or improve current skills are deductible. Education that qualifies you for a new trade is not (a software engineer learning new frameworks is deductible; a software engineer going to medical school is not).

Phone and internet at business-use percentage. Most freelancers use 70% to 90% of their home internet for work and a similar percentage of their phone. Document the methodology and apply it consistently. For a freelancer paying $80 per month for internet and $90 per month for phone with 80% business use, that’s an annual deduction of roughly $1,632.

Real example. A freelance copywriter we onboarded last year had been filing her own returns for three years. She had been deducting her business bank fees and her software subscriptions, but nothing else. We rebuilt her returns for the open three years adding home office, vehicle mileage to client meetings, self-employed health insurance, and a Solo 401(k) catch-up contribution. The amended returns produced refunds totaling roughly $11,000 across the three years. The home office alone was about $3,800 per year because she was paying $2,800 a month in rent in a downtown apartment and using a dedicated 130-square-foot office.

Documentation matters. Receipts for any expense over $75 are required by IRS guidance. Bank and credit card statements alone are not enough because they don’t show what was purchased. Use a tool like Hubdoc, Dext, or Expensify, or just a structured Google Drive folder per tax year. Take photos of receipts the day you get them. Reconstructing this at filing time produces incomplete records and missed deductions.

Where we help: identifying every legitimate deduction the freelancer has been missing, setting up bookkeeping systems that capture expenses throughout the year, choosing and administering retirement plans, modeling the entity structure (sole prop vs. LLC vs. S-corp) at different income levels, and preparing returns that properly claim every available deduction with the documentation to defend it. Most new Austin freelance clients see their effective tax rate drop by 5 to 10 percentage points just from picking up the deductions they didn’t know they could take.

The federal tax system is pay-as-you-go. W-2 employees pay through paycheck withholding. Self-employed people pay through quarterly estimated tax payments using Form 1040-ES. The IRS expects you to pay approximately one-quarter of your annual tax liability (income tax plus self-employment tax) each quarter. If you owe more than $1,000 of tax at filing time and didn’t pay enough through estimates, you’ll be charged an underpayment penalty even if you pay the full amount in April.

The 2026 quarterly deadlines are April 15, June 16 (the 15th falls on a Sunday), September 15, and January 15, 2027 for the fourth quarter of 2026. Payments can be made through IRS Direct Pay (free, from a bank account), EFTPS (free, from a bank account, requires enrollment), credit card (with a processing fee), or by mailing a check with Form 1040-ES voucher. Most Austin freelancers we work with use IRS Direct Pay because it’s free and works with any bank account without enrollment.

There are two safe harbors that protect you from the underpayment penalty regardless of what you actually owe at filing. Safe harbor one: pay at least 90% of the current year’s tax through estimates and withholding combined. Safe harbor two: pay 100% of the prior year’s tax (110% if your prior-year AGI exceeded $150,000) through estimates and withholding combined. Meeting either safe harbor means no underpayment penalty, period.

We almost always recommend the prior-year safe harbor for Austin freelancers because it’s predictable. You know exactly what your 2025 tax was, so you know exactly what to pay in 2026 estimates to be safe. If your 2025 tax was $24,000 and your 2025 AGI was under $150,000, paying $6,000 per quarter in 2026 ($24,000 total) protects you from underpayment penalty no matter what your actual 2026 income looks like. If your 2026 income jumps and your actual tax is $40,000, you’ll owe the additional $16,000 in April with no penalty.

The 110% rule for higher earners catches a lot of growing freelancers off guard. If your prior-year AGI was over $150,000, you have to pay 110% of prior-year tax (not just 100%) to hit the safe harbor. A freelancer with $30,000 of prior-year tax and prior-year AGI of $180,000 needs to pay $33,000 in current-year estimates to be safe (110% of $30,000). Paying only $30,000 means a possible underpayment penalty on the $3,000 difference even though it might seem like 100% should be enough.

Common mistake: freelancers who skip Q1 because their income is low at the start of the year and then try to catch up in Q2 or Q3. The IRS calculates underpayment penalty on a quarter-by-quarter basis, so being underpaid in Q1 generates penalty for Q1 even if you overpay later quarters. The penalty isn’t huge in most cases (currently around 8% annualized), but it’s avoidable just by paying something each quarter.

Real example. A freelance video editor in East Austin earned $40,000 in 2024 and $130,000 in 2025. He paid no estimated taxes in 2025 because he wasn’t used to it. At filing time in April 2026 he owed about $34,000 of federal tax, plus an underpayment penalty of approximately $1,200. We restructured his 2026 to use quarterly estimates based on the safe harbor (100% of his 2025 tax of $34,000, since his 2025 AGI of $125,000 was under the $150,000 threshold). He’s now paying $8,500 per quarter. Even if his 2026 income jumps to $200,000 and his actual tax balloons to $60,000, the additional $26,000 at filing time won’t generate penalty because he’s already met the safe harbor.

Documentation: keep records of every estimated tax payment (date, amount, confirmation number). These show up on your tax return as payments already made. IRS Direct Pay provides confirmation emails. EFTPS provides confirmation through the portal. If you mail checks, photograph the check and the voucher before sending. The IRS occasionally loses payments and you’ll need proof of payment to clear up the mismatch.

Quarterly estimates also apply to any state with income tax (Texas residents have no state estimate requirement). Freelancers who travel for work and earn income while physically in California, New York, or other states with income tax may have state estimate obligations even though Texas itself doesn’t. We review this for clients doing significant out-of-state work.

Where we help: calculating the right estimate amount each quarter based on year-to-date income, setting up automated reminders or auto-payments through bank bill-pay, troubleshooting payments that don’t show up on IRS records, structuring quarterly tax savings as a percentage of every client payment (so the money is set aside before it gets spent), and preparing the year-end return with all four quarterly payments properly credited. Freelancers who set up the cadence early avoid the April-bill shock that catches so many newcomers to self-employment.

The general rule we apply is that S-corp election starts to make financial sense when net freelance income consistently exceeds about $80,000 per year. Below that threshold, the SE tax savings from the election don’t usually cover the additional compliance costs. Above it, the savings start to compound, and by $120,000 or $150,000 of net income, the S-corp is a clear winner for most freelancers.

Here’s the math. A sole proprietor or single-member LLC pays SE tax of 15.3% on net earnings up to the Social Security wage base (roughly $184,500 for 2026). An S-corp owner pays themselves a reasonable W-2 salary, which is subject to payroll tax (employer plus employee shares total 15.3% on the salary portion up to the wage base). The remaining profit flows through to the owner as a distribution, which is not subject to payroll tax.

Example. An Austin freelance consultant with $150,000 of net profit operating as a sole proprietor pays SE tax of roughly $21,200 (15.3% on 92.35% of $150,000). The same freelancer operating as an S-corp with $80,000 of W-2 wages and $70,000 of distributions pays payroll tax (combined employer and employee shares) of roughly $12,240 on the wages and zero SE tax on the distributions. Net SE/payroll tax savings: approximately $8,960 per year. Over five years, that’s $44,800.

The cost side. S-corp compliance requires a separate tax return (Form 1120-S) with K-1 issuance to the owner. Payroll processing for the W-2 wages typically runs $40 to $80 per month through Gusto or a similar provider. A separate business bank account is required. Bookkeeping needs to be more rigorous because the S-corp is a distinct entity for federal tax purposes. Annual tax preparation for an S-corp typically runs $1,500 to $3,500 depending on complexity, versus $400 to $900 for a sole proprietor Schedule C add-on.

Net result for the $150,000 example: $8,960 of SE tax savings minus approximately $1,500 of additional compliance cost (payroll, bookkeeping, return prep) equals roughly $7,460 of annual net savings. At $80,000 of net income, the math gets thinner: SE tax savings of about $3,000 to $4,000 against the same $1,500 of additional cost produces $1,500 to $2,500 of net savings, which is real but smaller. Below $80,000, the savings often don’t cover the compliance.

The reasonable-compensation test is where S-corp owners get into trouble. The IRS expects the W-2 salary to reflect what a similarly skilled employee would earn for the same work. Owners who pay themselves zero wages and take all profit as distributions get audited and the distributions get reclassified as wages with back payroll tax and penalties. The reasonable comp number depends on industry, geographic location, experience, and the owner’s specific responsibilities. We anchor it to publicly available wage data (BLS, Glassdoor, ) for comparable roles in Austin, adjusted for the owner’s actual job mix.

A common rule of thumb is that W-2 wages should be 40% to 60% of total compensation, with distributions making up the rest. So a freelance consultant pulling $150,000 of net profit might pay themselves $75,000 to $90,000 in wages and take $60,000 to $75,000 in distributions. The right split depends on what comparable W-2 employees in similar roles earn. We document the reasonable-comp analysis annually so it’s defensible if the IRS asks.

Real example. An Austin web developer we work with elected S-corp status in 2022 when her net freelance income hit $145,000. We set her up on Gusto payroll with a $78,000 annual salary, leaving roughly $65,000 in distributions. Her SE/payroll tax savings was approximately $8,400 in year one against added compliance cost of about $1,400. By 2024 her business had grown to $220,000 of net income; we raised her salary to $95,000, and her net savings was approximately $12,000. The S-corp election was the single best tax move she made.

Other S-corp benefits beyond SE tax savings: ability to set up better retirement plans (the W-2 wages can support a Solo 401(k) with employee deferrals plus employer matching that mirrors how the freelancer would handle it anyway, just with cleaner tax treatment), simpler payment of health insurance premiums (the S-corp can pay the premiums and treat them as wages, reportable on the W-2 and deductible by the freelancer), and somewhat better audit posture compared to sole proprietors (S-corps are statistically less likely to be audited than Schedule C filers).

S-corp drawbacks: the additional administrative overhead (payroll runs, separate bookkeeping, separate tax return), reasonable compensation risk if the salary is set too low, and complications around basis tracking, AAA, and distributions in excess of basis. The election is also somewhat sticky; reversing an S-corp election usually requires a five-year wait before re-electing, so the decision should be made carefully.

Where we help: running the cost-benefit model based on the freelancer’s actual income and projected growth, handling the S-corp election filing (Form 2553), setting up payroll, documenting the reasonable-comp analysis annually, preparing the Form 1120-S and the owner’s personal return, and managing the basis and distribution mechanics. The election is usually a great move for freelancers in the $80,000 to $250,000 income range. Above that range, other strategies (defined benefit plans, structured retirement contributions, entity layering) start to add additional savings on top.

The IRS doesn’t audit most freelancers, but the freelancers it does audit are often Schedule C filers because the audit-success rate (in terms of additional tax assessed) is higher for self-employed taxpayers than for W-2 employees. Records are your only defense, and the time to organize them is throughout the year, not when an audit notice arrives.

Income records: every 1099-NEC and 1099-K received from clients and payment platforms, bank deposits matching client payments, invoices issued (whether through QuickBooks, FreshBooks, Stripe Invoicing, or a manual system), and any contracts establishing the engagement. The IRS expects total reported income to match or exceed the sum of 1099s received. If a client paid you $20,000 but issued a 1099 for $18,000, you still owe tax on the full $20,000. If your reported income is below the 1099 total, the IRS computer system flags it automatically and sends a notice.

Expense records: receipts for every business expense over $75, plus documentation of business purpose. Bank and credit card statements alone are not sufficient because they show the amount and vendor but not the nature of the purchase. For meals, the receipt should be accompanied by notes on who you met with and what you discussed. For travel, keep boarding passes, hotel folios, and a brief itinerary showing business purpose. For mileage, contemporaneous logs (not reconstructed after the fact) showing date, business purpose, and miles. Apps like MileIQ, Stride, and Hurdlr automate the log.

Home office records: photos of the dedicated space, square footage measurements (both the office space and the total home), rent receipts or mortgage statements, utility bills, internet bills, and homeowner’s or renter’s insurance. The IRS test is regular and exclusive use, so document that the space isn’t also a guest room or playroom. Some auditors will request photos showing the space free of personal use items.

Retirement contribution records: account statements showing contribution dates and amounts, plan documents (for Solo 401(k)s, the adoption agreement and any amendments), and records distinguishing employee deferrals from employer contributions. The contribution deadline for both SEP-IRA and Solo 401(k) is the tax filing deadline including extensions, but the funds must actually be deposited by that deadline. Keep proof of deposit.

Vehicle records: mileage log as described above, plus records supporting the deduction method chosen (mileage rate or actual expenses). If you use actual expenses, keep receipts for gas, insurance, registration, maintenance, repairs, and any other vehicle costs, along with total annual miles and business miles for the proration. The IRS typically requires consistent use of one method per vehicle from year to year.

Health insurance records: premium statements for the self-employed health insurance deduction (medical, dental, vision), 1095-A if coverage was through the ACA Marketplace, and proof of payment. The deduction applies only when the freelancer is not eligible for coverage through an employer or spouse’s employer. If the freelancer’s spouse has employer-sponsored coverage available (even if the family doesn’t enroll), the freelancer may not qualify for the self-employed deduction. We review eligibility annually.

Real example. A freelance graphic designer we onboarded had been audited by the IRS in 2023 for her 2021 return. She’d taken home office and vehicle deductions but had no contemporaneous documentation. The IRS disallowed both deductions, assessed additional tax of about $4,800 plus penalties and interest of roughly $1,800, totaling $6,600. We could have defended both deductions if she’d had the records. We spent her first year as our client setting up bookkeeping (QuickBooks Online), expense capture (Dext), and mileage tracking (MileIQ) so we’d have airtight records for future years.

Retention periods: the IRS can audit returns up to three years after filing in most cases, six years if there’s substantial omission of income (more than 25% understated), and indefinitely for fraud or unfiled returns. We tell clients to keep all tax records for at least seven years to be safe. Retirement account records and basis records for assets (stock purchases, business equipment, real estate) should be kept for as long as you own the asset plus seven years after sale or disposition. Storage is cheap. Cloud backup is cheaper. Don’t throw anything away.

Where we help: setting up year-round bookkeeping and expense-capture systems so audit-ready documentation is automatic, advising on what records to keep and how long, walking clients through audit notices when they arrive, representing clients before the IRS during audits (we handle audit defense for our return-prep clients), and preparing returns with documentation that supports every deduction taken. The freelancers who get hurt in audits are usually the ones with no records. The freelancers who walk away from audits with no changes are the ones who took the records seriously all year.
