How it's calculated
Set aside = self-employment tax + federal income tax on your net profit
- Net profit = 1099 income - business expenses.
- Self-employment earnings = net profit × 92.35%. Tax on that is 12.4% Social Security (up to $184,500.00) plus 2.9% Medicare, which is 15.3% in total.
- Taxable income = net profit - half of the self-employment tax - the standard deduction. Income tax uses the 2026 federal brackets.
- Additional Medicare tax of 0.9% is added above the filing-status threshold.
- Share to set aside = total federal tax ÷ 1099 income.
It assumes this is your only income, uses the standard deduction, and leaves out credits and state tax. The rates are the same ones used by the quarterly tax calculator.

What counts as 1099 income?
Money paid to you for work outside a regular job: forms like 1099-NEC (contract work), 1099-K (card and app payments) and 1099-MISC. The IRS says self-employment income is taxable even when no form is sent to you, so add up everything you earned, not only what the forms show.
Expenses that can lower your 1099 tax
Tax is figured on profit, so each valid business cost lowers it. IRS Publication 535 covers common ones:
- Car and truck costs: actual expenses or the standard mileage rate (see the mileage deduction calculator).
- Supplies, tools and materials used in the business.
- Business insurance, legal and professional fees, and software.
- The business share of your phone and internet.
- Rent and utilities for business space, or a home office that meets the IRS rules.

How to pay 1099 taxes
Most 1099 workers pay estimated tax during the year instead of one bill in April. You can pay online with IRS Direct Pay or by mail with Form 1040-ES. Use the quarterly tax calculator to split the total into four payments and see the due dates. Self-employment tax is reported with Schedule SE when you file.

FAQ
How much tax do I pay on 1099 income?
Most 1099 income is taxed twice: 15.3% self-employment tax on 92.35% of your profit, plus regular federal income tax on what is left after deductions. Your own bracket decides the second part, so the total changes with your profit. This calculator shows both parts for 2026.
How much should I set aside from every 1099 payment?
The calculator gives you a percentage of your 1099 income, and the amount to set aside from every $1,000. Move that share into a separate savings account each time you are paid, so the tax bill is already covered when it is due.
Do business expenses lower my 1099 tax?
Yes. Tax is figured on your net profit, which is 1099 income minus the business expenses you can deduct. Every dollar of a valid deduction lowers both the income tax and the self-employment tax. The calculator shows how much your expenses save you. Keep a receipt for each one.
What is a 1099 form?
A Form 1099 (such as 1099-NEC or 1099-K) reports payments made to you outside a regular job. It is not a bill. You owe tax on the income whether or not a form is sent to you.
Does this include state tax?
No. It estimates U.S. federal tax only. Many states also tax self-employment income, so add your state's rules separately.
Is this calculator exact?
No. It is an estimate. It uses the standard deduction, the half self-employment tax deduction and the federal tax brackets, and assumes this is your only income. It does not include credits, the qualified business income deduction, itemized deductions or other income. Ask a tax professional before you file.
