The 1099 vs W-2 Take-Home Calculator computes true after-tax take-home pay for both W-2 employment and 1099 / self-employment situations using verified 2025 federal tax parameters. It is designed for people evaluating a contract rate against a salaried offer, or workers considering a transition to self-employment.
The calculator models: employee FICA taxes (IRC §3101), self-employment tax (Schedule SE, IRC §1401–1402), the above-the-line deduction for half of SE tax (IRC §164(f)), the self-employed health insurance deduction (IRC §162(l)), the §199A Qualified Business Income deduction, employer benefit valuation (health insurance, 401k match, PTO), and a breakeven revenue calculator.
Built by Officina Systems. Math independently verified against IRS Schedule SE instructions, IRC statutory text, and 2025 bracket tables published in Rev. Proc. 2024-40. All calculations run client-side in your browser — no data is transmitted or stored.
Federal tax only. State income taxes not modeled. SSTB QBI limitations not applied. Retirement plan contribution deductions (SEP-IRA, Solo 401k) not modeled. This tool is for educational estimation only — not tax or legal advice. Consult a licensed CPA for personalized guidance.
