Example: a freelance developer earning $120,000 in Texas
A single filer with $120,000 of freelance developer income and $10,200 of deductible business expenses owes about $25,352 for 2026 — 21.1% of gross income. That means setting aside 21% of every payment, or about $6,338 a quarter if paid in four equal installments.

Freelance Developer tax questions
How much should I set aside from a 1099 contract?
The 25–30% rule of thumb is usually too high below $100,000 of profit and too low above $200,000. After the standard and QBI deductions, most single developers billing $75,000–$150,000 need 17–25%, depending on state. The calculator gives your exact set-aside rate.
Should I form an S corporation?
An S-corp election can reduce self-employment tax by paying yourself a reasonable salary, but it adds payroll, a separate return and state fees. It usually starts to pay off at higher profit levels — run the numbers with a CPA.
Are cloud and API costs deductible?
Yes, when they're for client work or your business: hosting, domains, GitHub, CI minutes and LLM API usage billed to you.
Do I have to pay quarterly estimated taxes?
If you expect to owe $1,000 or more in federal tax after withholding, the IRS expects four estimated payments (Form 1040-ES): April 15, June 15, September 15 and January 15. Paying at least 90% of this year's tax, or 100% of last year's (110% if your AGI was over $150,000), avoids the underpayment penalty.
What is self-employment tax?
It's Social Security and Medicare for people without an employer: 15.3% of 92.35% of your net profit, on top of income tax. Social Security (12.4%) stops at $184,500 of combined wages and self-employment earnings in 2026; Medicare (2.9%) has no cap. You deduct half of it when figuring income tax.
2026 quarterly estimated tax due dates
Self-employed people pay income and self-employment tax four times a year with Form 1040-ES. Each payment covers income earned in the period shown; if a date falls on a weekend or holiday, it moves to the next business day.
| Payment | Income earned | Due date |
|---|---|---|
| Q1 | Jan 1 – Mar 31 | |
| Q2 | Apr 1 – May 31 | |
| Q3 | Jun 1 – Aug 31 | |
| Q4 | Sep 1 – Dec 31 |
Pay online with IRS Direct Payor EFTPS and choose "1040-ES estimated tax". To avoid the underpayment penalty, pay at least 90% of this year's tax or 100% of last year's (110% if last year's AGI was over $150,000) across the four dates.
How the calculator works
- Net profit. Gross creator income minus deductible business expenses (meals at 50%), as on Schedule C.
- Self-employment tax. 15.3% of 92.35% of net profit — 12.4% Social Security up to the $184,500 wage base (reduced by any W-2 wages) plus 2.9% Medicare, and 0.9% additional Medicare above $200,000 ($250,000 married filing jointly).
- Federal income tax. 2026 brackets applied after the standard deduction, half of self-employment tax, and the 20% qualified business income (QBI) deduction.
- State tax. Each state's 2026 flat rate or brackets; states without an income tax add nothing.
- Quarterly payments. The year's balance spread over the four 1040-ES dates, with the 90% / 100% / 110% safe-harbor minimums shown.
