How the Calculation Works

1
Net SE Income Net = Gross 1099 Income − Business Expenses

Only deductible business expenses reduce your SE income. Personal expenses do not qualify.

2
SE Tax Base SE Base = Net × 92.35%

The IRS applies a 92.35% factor (= 1 − 7.65%) because employees don't pay the employer half of FICA — the 7.65% adjustment mimics that for self-employed individuals. Source: IRS Topic 554, as of 2026-06-12.

3
SE Tax SE Tax = min(SE Base, $184,500) × 12.4% + SE Base × 2.9%

Social Security (12.4%) applies only up to the $184,500 wage base for 2026. Medicare (2.9%) has no cap. An additional 0.9% Medicare surtax applies above $200,000 (single) or $250,000 (MFJ). Source: IRS Topic 751, as of 2026-06-12.

4
SE Tax Deduction SE Deduction = SE Tax ÷ 2

You deduct the employer-equivalent half of SE tax from gross income before computing income tax (Schedule SE / Form 1040 line 15).

5
Federal Taxable Income Taxable = Net + Other Income − SE Deduction − Standard Deduction

Standard deduction for 2026: $16,100 (Single / MFS), $32,200 (MFJ), $24,150 (Head of Household). Source: IRS Rev. Proc. 2025-32, as of 2026-06-12.

Quarterly Payment Quarterly = Total Annual Tax ÷ 4

If you entered a prior-year tax, the calculator also shows the safe-harbor amount (prior-year tax ÷ 4), and uses whichever is lower to avoid underpayment penalties.

Frequently Asked Questions

How much should I set aside for taxes on 1099 income?

A common rule of thumb is 25–30% of every payment. The exact amount depends on your total income, filing status, deductions, and state tax rate. This calculator gives you a personalized estimate based on your actual numbers.

What is self-employment (SE) tax and why is it so high?

Self-employment tax is 15.3% on 92.35% of your net self-employment income. It covers Social Security (12.4%) and Medicare (2.9%). When you work as an employee, your employer pays half of these; as a self-employed person you pay both halves. You can deduct the employer-equivalent half (about 7.65%) when calculating your income tax.

What is the Social Security wage base for 2026?

The Social Security wage base for 2026 is $184,500. Only income up to this amount is subject to the 12.4% Social Security portion of SE tax. The 2.9% Medicare tax has no cap. Source: IRS Topic 751, verified June 2026.

When are 2026 quarterly estimated tax payments due?

The four 2026 due dates are: Q1 — April 15, 2026; Q2 — June 15, 2026; Q3 — September 15, 2026; Q4 — January 15, 2027. See our Quarterly Tax Due Dates page for details and the underpayment penalty rule.

Does this calculator account for business deductions?

It accounts for business expenses you enter, which reduce your net SE income before tax is calculated. It does not itemize every possible deduction (home office, vehicle, etc.). For a full deduction review, see our 1099 Deductions Checklist page.

Is the state tax calculation accurate?

State tax is estimated by multiplying your federal AGI by the rate you enter. Every state has different rules, brackets, and deductions — this is a planning estimate, not a precise state return. Enter your state's flat or effective rate and verify at your state revenue department website.
