    How 401(k) deferrals change take-home

    Traditional 401(k) contributions skip federal and state income tax (not FICA). The 2026 employee limit is $24,500 (+$8,000 catch-up at 50+). Deferring 10% of a $100,000 salary cuts taxable income by $10,000 and costs only ≈ $7,600 of net pay for a 24%-bracket earner.

    Roth deferrals invert the timing: full tax now, tax-free later. The calculator models traditional deferrals; treat Roth contributions as after-tax allocations from the net figure.

    From federal net to your actual paycheck

    Add your state to finish the picture: the same $100,000 nets between $71,439 (Oregon) and $79,180 (no-tax states) across the covered set – a spread of $7,741/year on identical gross pay.

    Then layer pre-tax benefits (401(k), health, HSA) – each reduces the taxable base before these rates apply, which is why two colleagues on identical salaries see different withholding.

    FAQ

    Frequently asked questions

    How much federal tax on $100,000?

    $13,170 of income tax plus $7,650 FICA in 2026 (single, standard deduction) – total 20.8% effective, leaving $79,180 before state tax.

    What are the 2026 federal brackets?

    Seven rates – 10%, 12%, 22%, 24%, 32%, 35%, 37% – applied to taxable income slices after the standard deduction (see table). The thresholds are inflation-indexed annually.

    What is FICA exactly?

    Social Security 6.2% (to $184,500) + Medicare 1.45% (+0.9% above $200k) – flat payroll taxes with no deductions, matched by your employer.

    Married vs single – how big is the difference?

    At $100,000 single-income, filing jointly saves $5,530/year via doubled brackets and the $32,200 deduction. Dual-earner couples see smaller (sometimes negative) deltas.

    Why is my actual paycheck different?

    State tax, pre-tax benefits, W-4 elections, and bonus-withholding rules all layer onto the federal base modeled here – the calculator accepts each as an input.
