Why doesn’t this match my paycheck?

Payroll systems use your W-4, benefits, pre/post-tax deductions, and state rules. Federal income tax here uses 2025 IRS brackets and standard deduction; state tax is still a rough flat rate. Employer withholding for additional Medicare often starts only after $200k of wages from that job, which can differ from annual tax for married couples with two incomes.

Are 401(k) contributions modeled accurately?

Traditional deferrals reduce federal taxable income in this simplified model. FICA is still applied on wages consistent with typical employee deferrals.

Can I rely on this for tax filing?

No. It is for directional education only. Consult the IRS, your state, or a tax professional for filing.

Salary Take-Home Pay Calculator

Enter gross annual salary, filing status, and common pre-tax items to see a rough after-tax take-home split. Federal figures follow tax year 2025 brackets and standard deduction; FICA includes additional Medicare on high earners. State tax remains a simplified flat rate—not your real return. Credits, W-4 withholding timing, local wage taxes, and SDI are not modeled.

Educational only. Federal figures follow IRS tax year 2025 brackets, standard deduction ($15,750 single / $31,500 married filing jointly), Social Security wage base ($176,100), Medicare 1.45%, and additional Medicare 0.9% above $200k (single) / $250k (MFJ) on modeled Medicare wages. State rates stay illustrative. Not your W-4, AMT, local taxes, SDI, or exact withholding—dual earners may owe additional Medicare differently than one W-2 shows. HSA/insurance reduce federal taxable income and FICA wages here; traditional 401(k) reduces federal taxable only (still subject to FICA in this model).

Taxes as a share of gross

Effective tax rate here is the average slice of your gross salary that goes to federal income tax, state tax (illustrative), Social Security, and Medicare (including additional Medicare when applicable)—combined. It is not the same as your top marginal bracket, and it does not use “taxable income” in the denominator.

($18,673 ÷ $92,000 gross) × 100 ≈ 20.3%
