Where the Money Goes
The gap between a salary and a paycheck is larger than most people expect. On $85,000 with ordinary deductions, roughly $27,000 never reaches the bank account — about a third of the headline figure. Five separate deductions produce that gap, and they are taken in a specific order that matters.
The Order of Deductions
- Pre-tax deductions — 401(k), health premiums, HSA and FSA. These reduce taxable income.
- FICA — Social Security at 6.2% up to $176,100 and Medicare at 1.45% with no cap. Health premiums reduce FICA wages; 401(k) contributions do not.
- Federal income tax — on income after the standard deduction and pre-tax items.
- State and local tax — from 0% in nine states to over 13% at the top in California.
- Post-tax deductions — Roth 401(k), garnishments, union dues, some insurance.
The 401(k) quirk is worth knowing: contributions escape income tax but not payroll tax, so a $6,000 contribution saves federal tax but still pays $459 in FICA.
Pay Frequency Does Not Change the Total
Biweekly pay produces 26 cheques a year, semimonthly 24. The annual total is identical; only the size and timing differ. Biweekly pay creates two months a year with three cheques, which feels like a bonus and is simply arithmetic.
Withholding Is an Estimate, Not the Tax
Payroll withholding is a projection based on your W-4. A refund means you lent the government money at 0% all year; a bill means the opposite. Neither changes what you owe. Adjusting the W-4 to land near zero is strictly better than a large refund, though many people prefer the enforced saving.
State Tax Varies Enormously
| State | Top rate | Effect on $85,000 |
|---|---|---|
| Texas, Florida, Washington, Nevada | 0% | $0 |
| Pennsylvania | 3.07% flat | about $2,600 |
| Illinois | 4.95% flat | about $4,200 |
| New York | up to 10.9% | about $4,600 |
| California | up to 13.3% | about $5,000 |
A $95,000 offer in Texas and a $100,000 offer in California are close to identical in take-home terms — before the difference in housing costs.
Frequently Asked Questions
Why did my paycheck change mid-year?
Most often because Social Security stopped withholding once you passed $176,100 in wages, which raises take-home pay for the rest of the year. Benefit changes and bonus withholding at the flat 22% supplemental rate also do it.
Should I increase my 401(k) contribution?
At least to the full employer match, always. Beyond that, each extra dollar reduces take-home by roughly 70–78 cents rather than a full dollar, because the tax saving offsets part of it.
How is a bonus taxed?
Withheld at a flat 22% federally if under $1 million, which is a withholding rule rather than a tax rate. The bonus is taxed as ordinary income when you file, so the difference is settled at that point.
