Inputs

Enter your ZIP to compute local city tax.

True gross — what you earn before any pre-tax payroll deductions are taken out. Add back 401(k), HSA, and § 125 amounts that come off Box 1.

Pre-tax contributions

Each line behaves differently for FICA — see the help text on each field. Caps depend on age (50+ catch-up, 60–63 super-catch-up) and HDHP coverage.

Reduces federal taxable wages. Not FICA-deductible — § 3121(a)(5) keeps elective deferrals in SS/Medicare wages.

Above-the-line federal deduction; not FICA. § 219(g) phase-out applied automatically when you have any 401(k) (we treat that as workplace-plan coverage). The result panel shows the post-phase-out deductible amount.

Determines the HSA contribution cap below.

Through-payroll only (Code W on W-2). Reduces both federal taxable wages and FICA.

Outside-payroll contributions claimed on Form 8889. Federal deduction only — no FICA savings (no § 125 cafeteria-plan treatment for outside-payroll deposits).

Leave at 0 to use the standard deduction. Calculator takes the larger of standard or itemized.
