How a Raise Affects Your Take-Home Pay: Tax Impact of Salary Increases (2026)

A raise increases gross pay, but the full increase does not arrive in your bank account. Payroll withholding and FICA also change. The useful negotiation number is the net increase after modeled withholding.

Engine-Derived Texas Example: $75,000 to $90,000

This comparison uses a single filer in Texas, biweekly pay, a standard W-4, and no optional pre-tax deductions.

Scenario	Gross annual	Net annual
Before raise	$75,000	$61,593
After raise	$90,000	$72,145

Gross increase: $15,000. Net increase: $10,553. Modeled tax on raise: $4,448.

Use Net Pay in Salary Negotiation

Compare offers with the same state, filing status, pay frequency, and deductions. A marginal tax bracket applies only to the portion of income above its threshold.

Gross offer vs net take-home

Salary negotiations often focus on gross annual pay, but net take-home determines spending power. A $10,000 gross increase does not produce $10,000 extra net pay because federal income tax, FICA, and state withholding all apply to the marginal dollars.

Marginal withholding on raises

Federal withholding on additional salary follows your marginal bracket under IRS Publication 15-T — not your effective rate on all income. Progressive states add state marginal withholding on top. No-income-tax states preserve more of each marginal dollar than high-tax states.

FICA on salary increases

Social Security is 6.2% on gross up to the annual wage base; Medicare is 1.45% on all wages. A raise increases FICA withholding until you hit the Social Security cap. High earners see reduced Social Security withholding in later paychecks once year-to-date wages exceed the cap.

Pre-tax benefits in negotiations

Employer 401(k) match, HSA contributions, and pre-tax health insurance reduce taxable wages. A lower gross offer with generous pre-tax benefits can produce similar net pay to a higher gross offer without benefits. Model both in the paycheck calculator.

State relocation in offers

Comparing offers in different states requires state-specific calculator runs at the same gross salary. Moving from a progressive state to a no-income-tax state increases net pay even at identical gross. See moving states tax impact and state comparison pages.

Sign-on bonus vs base salary

Sign-on bonuses often use supplemental withholding methods that reduce the first-check net compared to base salary spread across the year. See bonus vs salary tax difference for structural guidance on bonus-heavy offers.

Equity compensation

RSU and stock option grants add taxable income at vest or exercise — not at offer signing. Factor equity vest schedules into multi-year net pay planning. See RSU tax guide for vest-year withholding spikes.

Negotiation checklist

Compare net pay at identical assumptions using salary band pages and state calculators. Include filing status, pay frequency, and expected pre-tax deductions. Consult a qualified professional for complex equity or multi-state scenarios.

Frequently Asked Questions

Cost-of-living adjustments in offers

Employers in expensive metros sometimes embed COLA in gross salary. Compare net pay after state and local withholding — not just gross COLA — when evaluating geographic pay differences. See cost of living salary comparison.

Benefits beyond 401(k)

Stock grants, profit sharing, and deferred compensation change multi-year tax profiles beyond base salary withholding. Model base pay in the calculator; treat equity separately using RSU and stock option guides.
