Why is my effective tax rate so much lower than my bracket?

Brackets are marginal: on $70,000 of taxable income, only the amount above $48,475 is taxed at 22% — the first $11,925 is taxed at 10% and the next slice at 12%. That's why an $85,000 earner in the '22% bracket' pays about 12.1% of gross in federal income tax, not 22%.

Does a raise into a higher bracket reduce my take-home?

No — this is the most persistent tax myth. Only the dollars above the bracket threshold are taxed at the higher rate; every raise increases net pay. (Certain benefit cliffs — subsidy phase-outs, income limits — can create exceptions, but the tax brackets themselves never can.)

How do 401(k) contributions change my paycheck?

Traditional 401(k) contributions come out pre-tax, so a $100 contribution costs well under $100 of take-home — at a 22% marginal federal rate plus 5% state, roughly $73. FICA still applies to 401(k) contributions. Roth 401(k) contributions are post-tax: full cost now, tax-free withdrawals later.

What is FICA and can I reduce it?

FICA is Social Security (6.2%, on wages up to the annual cap) plus Medicare (1.45%, uncapped; +0.9% surtax above $200,000 single). Unlike income tax, standard deductions and 401(k) contributions don't reduce it — though pre-tax Section 125 health premiums and HSA payroll contributions do.

Why does my paycheck differ from this estimate?

Withholding (what your employer sends the IRS each period, driven by your W-4) isn't the same as your actual tax liability. Bonuses withheld at flat rates, multiple jobs, itemized deductions, and credits all create gaps — settled at filing time as a refund or balance due.

Quick answer

Where does an $85,000 salary actually go?

A single filer earning $85,000 pays about $10,314 in federal income tax for 2025 (taxable income $70,000 after the $15,000 standard deduction) — an effective federal rate of about 12.1%, even though the marginal bracket is 22%. FICA adds a flat 7.65% ($6,503). State tax, 401(k) contributions, and health premiums then shape the final paycheck — the calculator breaks down each per-period deduction.

Frequently asked questions

How we built this tool

How we compute net pay

Step 1

Pre-tax first, then federal taxable

401(k) and health premiums come off gross before any tax. Then the 2025 standard deduction comes off federal taxable income. State tax uses the full AGI — most states don't mirror federal deductions.

Step 2

FICA is two taxes, not one

6.2% Social Security (capped at $184,500 of wages in 2026; was $184,500 in 2025) + 1.45% Medicare (uncapped). High earners pay an extra 0.9% Medicare over $200K single / $250K MFJ.

Step 3

State rate is simplified

We use a flat state rate for transparency. Real state brackets vary — California is progressive up to 13.3%, Texas is 0%. Use your state's top bracket for a conservative estimate.
