If you’re a single freelancer with no other income, federal tax for 2026 comes to roughly 17% to 27% of your net profit in the $30,000 to $200,000 range. The more you earn, the higher the percentage. That covers self-employment tax and federal income tax. State income tax, where your state has one, comes on top. The table below breaks it down by income level. Every figure comes from the IRS’s 2026 tax rate schedule and worksheets in Form 1040-ES.

Our estimate using the 2026 Form 1040-ES worksheets and tax rate schedule: single filer, sole proprietor, no other income, $16,100 standard deduction, 20% qualified business income deduction, no credits, retirement contributions or health insurance deduction. Federal only — state and local income tax are not included. Rounded to the dollar.
The rate climbs with income for two reasons. Self-employment tax takes a nearly flat ~14% of profit up to the Social Security cap. Income tax is progressive, so each extra dollar gets taxed at a higher bracket. At $30,000, self-employment tax is most of the bill. At $200,000, income tax is almost as large as the self-employment tax.
How we got these numbers
Each row follows the same steps as the IRS’s 2026 Estimated Tax Worksheet. Here’s the $100,000 row in full:
- 1$100,000
Net profit
- 2$14,129
Self-employment tax
$100,000 × 92.35% = $92,350; × 12.4% = $11,451 + × 2.9% = $2,678
- 3−$7,065
Deductible half of SE tax
$14,129 × 50%, rounded
- 4$92,935
Adjusted gross income
- 5−$16,100
Standard deduction (single, 2026)
- 6−$15,367
QBI deduction
20% × the smaller of $92,935 or $76,835
- 7$61,468
Taxable income
- 8$8,235
Federal income tax
$5,800 + 22% × ($61,468 − $50,400)
- 9$22,364
Total federal tax
$8,235 + $14,129
- 1022.4%
Share of net profit
$22,364 ÷ $100,000
Rounded to the dollar at each step, as on the IRS worksheets. Same assumptions as the table above.
The inputs, all for 2026 and all from IRS sources:
- Self-employment tax: 12.4% Social Security plus 2.9% Medicare on 92.35% of net profit, with Social Security capped at $184,500 of earnings, per the Form 1040-ES worksheet. Half is deductible. See Self-Employment Tax Explained for the details.
- Standard deduction: $16,100 for single filers, per Form 1040-ES.
- Qualified business income deduction: up to 20% of QBI, limited to 20% of taxable income, per the IRS. Every row in the table stays below the 2026 threshold of $201,750, where extra limits start to apply (Rev. Proc. 2025-32).
- Tax brackets: the 2026 Schedule X (single) rate schedule printed in Form 1040-ES.
- Additional Medicare Tax (0.9% above $200,000 for single filers, per Publication 505): it doesn’t apply to any row, because even at $200,000 of profit, net earnings are $184,700.
A practical system for setting money aside
- Estimate your net profit for the year. Use last year’s as a starting point, adjusted for what you expect to change.
- Find your percentage in the table, or run the full quarterly estimated tax calculation for your situation. Add your state’s income tax if you have one.
- Move that percentage of every client payment into a separate savings account the day it arrives. Doing it per payment, rather than once a quarter, means the money is already there when a deadline comes.
- Pay your estimated taxes from that account by each 2026 due date: April 15, June 15 and September 15, 2026, and January 15, 2027.
- Check your pace once a quarter. If income is running ahead of your estimate, raise the percentage for the rest of the year.
What makes your number higher or lower
The table is a starting point, not your actual bill. Common reasons yours will differ:
- State and local income tax. Not included above. Depending on where you live, this can add nothing or several percentage points.
- Retirement contributions. Solo 401(k) and SEP IRA contributions can reduce your income tax. Our Self-Employed Retirement Contribution Calculator estimates how much you can put in.
- A W-2 job or a spouse’s income. Extra income pushes your self-employment profit into higher brackets. Wages also use up part of the $184,500 Social Security cap.
- Filing status. Married filing jointly has a $32,200 standard deduction for 2026 and wider brackets.
- Credits and other deductions, such as the self-employed health insurance deduction or the child tax credit.
Setting aside isn’t the same as prepaying the minimum
The percentages above aim to cover your full federal tax bill. The IRS’s minimum prepayment to avoid a penalty can be lower. It’s the smaller of 90% of this year’s tax or 100% of last year’s (110% if last year’s AGI was over $150,000), per Form 1040-ES. You can prepay the minimum and settle the rest when you file, but that rest still has to come from somewhere. Setting aside the full amount means there’s no surprise in April. See Estimated Tax Deadlines for 2026 and the Safe Harbor Rule for how that minimum works.
Bottom line
For a single freelancer, putting aside about a fifth of net profit covers federal tax at moderate incomes, and closer to a quarter at $150,000 and up. Add your state’s income tax on top. Keep the money in its own account, pay it out each quarter, and adjust once a quarter as your income becomes clearer.
