How this estimate works

A simplified federal model based on IRS Schedule SE and Form 1040 mechanics. Your actual tax return may differ.

  • Net self-employment income

    Enter net profit after business expenses (Schedule C line 31 equivalent). This calculator does not subtract expenses for you.

  • Net earnings subject to SE tax

    Schedule SE applies a 92.35% net earnings factor before computing Social Security and Medicare tax on self-employment income.

  • Self-employment tax components

    Social Security and Medicare portions use IRS Schedule SE rates for 2025, including the Social Security wage base cap where applicable.

  • Deductible portion of SE tax

    One-half (50%) of self-employment tax is deductible when calculating adjusted gross income, which can reduce federal income tax.

  • Federal income tax

    Federal income tax uses 2025 brackets and the standard deduction from IRS publications for your filing status. Itemized deductions are not modeled.

  • Quarterly payment estimate

    The suggested quarterly amount divides estimated annual federal tax into four equal payments for planning. Safe harbor rules and prior-year comparisons are not fully modeled here.

  • Known exclusions

    State and local taxes, tax credits, the QBI deduction (Section 199A), underpayment penalties, AMT, and retirement or health deductions are excluded from this estimate.

Frequently asked questions

Self-employment tax is Social Security and Medicare tax for people who work for themselves. It is reported on Schedule SE and is separate from federal income tax.

This calculator follows Schedule SE: net self-employment profit is multiplied by 92.35% to get net earnings, then Social Security and Medicare rates apply (15.3% combined before wage-base limits). Half of SE tax may reduce AGI for income tax.
