Breakdown
Formula
The math behind the result
Net profit = gross receipts − ordinary business expenses
SE net earnings = net profit × 92.35%
SE tax = 12.4% Social Security (to the 2026 wage base) + Medicare components
Taxable income = net profit - deductible half of regular SE tax - other adjustments - standard deduction
Federal tax = sum of progressive bracket rates on taxable income

FAQ
Common questions
What is 1099 income?
Form 1099-NEC can report nonemployee compensation, but the tax calculation starts from the business's net profit, not the form amount alone. Estimated payments may be required depending on expected tax, withholding, credits, prior-year tax, and timing of income.
What is self-employment (SE) tax?
The regular components are 12.4% Social Security and 2.9% Medicare on the applicable net earnings calculation. Social Security has a 2026 wage base, Medicare does not, and an additional 0.9% Medicare tax can apply above the filing-status threshold. W-2 wages can change the result and are outside this baseline.
When are quarterly estimated taxes due?
For calendar-year 2026, the general dates are April 15, June 15, September 15, 2026, and January 15, 2027. Required amounts are not automatically one quarter of this estimate; IRS safe-harbor and annualized-income rules can change each installment.
Can I deduct business expenses from 1099 income?
Ordinary and necessary business expenses can reduce Schedule C net profit when the specific expense qualifies and is documented. Health insurance, retirement contributions, home-office expenses, vehicles, and equipment can follow different rules, so do not enter a personal payment merely because it is work-related.
What percentage of my 1099 income should I save for taxes?
There is no universal safe percentage. Federal income tax, self-employment tax, state tax, other income, credits, withholding, and safe-harbor rules all affect the amount. Use the result as a scenario and calculate required payments from Form 1040-ES or professional software.
