Texas Self-Employment Tax Calculator — 2026
Calculate your self-employment tax liability including Social Security and Medicare contributions. Free calculator with Texas-specific rates.
Texas is one of the best places in America to be self-employed, for one simple reason: no state income tax. While freelancers in California and New York stack state brackets on top of their federal bills, Texas contractors keep the entire state layer. Your total tax picture is the 15.3% federal self-employment tax — 12.4% for Social Security on the first $184,500 of net earnings in 2026 and 2.9% for Medicare on everything — plus federal income tax, which every American pays regardless of state.
The self-employment tax itself works the same in Dallas as it does in Denver. You multiply net profit by 92.35%, apply 15.3%, and the result is your SE tax bill. An additional 0.9% Medicare surtax kicks in above $200,000 for single filers. What makes Texas different is the state-level calculus: instead of income taxes, Texas uses a franchise tax on businesses with revenue over $2.47 million — which most solo freelancers and contractors will never approach.
Texas self-employed workers still owe quarterly estimated payments to the IRS, and that surprises many newcomers. The state may not send you a bill, but the IRS certainly will: April 15, June 16, September 15, and January 15 deadlines apply to anyone expecting to owe $1,000 or more. The good news is that with no state withholding or state estimates to manage, your quarterly math is simpler than almost anywhere else.
From Austin's tech freelancers to Houston's energy consultants and San Antonio's creative contractors, the Texas self-employment playbook is the same: track every business expense, take the 50% SE tax deduction and the 20% QBI deduction, and set aside roughly 25-30% of net profit for federal obligations. This calculator does the full math — including your federal brackets — so you know your number in seconds.

How to Use This Calculator
Start by entering your annual gross self-employment income — the total amount you earned before any deductions. This includes 1099 payments, cash income, and any side business revenue. Next, enter your business expenses: home office costs, equipment, software subscriptions, professional services, vehicle expenses, and other deductible costs. The calculator subtracts these to find your net profit.
Select Texas from the state dropdown so the tool applies the correct state income tax rates. Review the summary screen showing your net profit, self-employment tax, income tax, and total tax liability. Use the detailed breakdown to see exactly how each component was calculated — including the Social Security portion, Medicare portion, and the 50% SE tax deduction. Finally, compare your Texas tax burden against other states and generate a quarterly payment plan.
Why Getting This Right Matters
Underpaying self-employment tax triggers IRS penalties and interest — currently 8% annually on underpayments. Texas residents who miss quarterly estimated payments face additional state penalties. Overpaying means locking up money you could invest in your business. Accurate calculation is the difference between a safe tax strategy and an expensive surprise at filing time.
Self-employment tax is also your contribution to Social Security and Medicare — the same programs W-2 employees fund through payroll withholding. Your 2026 net earnings count toward your Social Security benefits calculation, so underreporting income to reduce self-employment tax also reduces your future retirement and disability benefits.
