How to use this calculator
Enter your net self-employment income (1099 profit after business expenses) and your filing status. The calculator stacks the two taxes every contractor owes: the 15.3% self-employment tax and federal income tax at 2026 brackets after the standard deduction.

The formula
Self-employment tax = net earnings × 92.35% × 15.3%. Federal income tax = progressive brackets applied to (net earnings − half of SE tax − standard deduction). Your total = both added together. State income tax is not included.
Example: $80,000 as a single filer
SE tax = $73,880 × 15.3% = $11,303.64. Taxable income = $80,000 − $5,651.82 (half SE tax) − $16,100 (standard deduction) = $58,248.18, which produces $7,526.60 of federal income tax. Total estimated 2026 federal tax = $18,830.24, an effective rate of 23.54%.
FAQ
How much tax do I owe on 1099 income?
Contractors pay two layers: a 15.3% self-employment tax on 92.35% of net profit, plus regular federal income tax after deducting half the SE tax and the standard deduction. On $80,000 of net income (single, 2026), that totals about $18,830.
Why is 1099 income taxed more than W-2 income?
Employers pay half of FICA for employees. As a 1099 contractor you pay both halves via the self-employment tax, which is why 1099 income carries roughly 7.65% more payroll tax before deductions.
Does the standard deduction apply to 1099 workers?
Yes. Self-employed filers take the same standard deduction as everyone else ($16,100 single / $32,200 married filing jointly in 2026), on top of business expense deductions and half of the SE tax.
Are state taxes included?
No. This calculator covers federal SE tax and federal income tax only. State income tax varies widely and should be estimated separately.
