2026 Federal Paycheck Calculator

Loading calculator...

Estimate a paycheck using 2026 federal ordinary-income brackets, the standard deduction or an entered itemized deduction, employee Social Security and Medicare taxes, and selected pretax deductions.

State and local taxes are not included. This is an annualized tax-liability scenario, not an employer payroll system or a Form W-4 withholding calculation.

How It Works

The tool annualizes salary or hourly pay, subtracts entered pretax deductions for the simplified adjusted-gross-income scenario, applies the selected deduction and calculates federal tax progressively across the official 2026 brackets. It then estimates employee Social Security up to the 2026 wage base and Medicare tax, and divides annual amounts by the selected number of pay periods.

401(k) and HSA entries are capped at the modeled 2026 regular limits. Actual tax treatment can depend on plan, coverage, age, employer and payroll details.

Understanding Your Results

“Federal income tax” is a simplified annual liability divided by pay periods; it may not match payroll withholding. “Net pay” is before state and local income taxes and excludes credits, tips and overtime deductions, bonuses, self-employment tax, many Form W-4 adjustments and benefit-specific payroll rules.

Use the result as a reconciliation prompt

Compare the estimate with a pay stub to find missing state tax, local tax, insurance, retirement, garnishment or payroll-specific items. For actual withholding, use the current IRS Tax Withholding Estimator and your recent pay statements.

Frequently Asked Questions

Does this calculator include state income tax?
No. It estimates federal income tax and employee FICA only. State and local taxes must be added separately.
Is this the same as Form W-4 withholding?
No. It estimates annual federal liability from simplified inputs and divides it by pay periods; payroll withholding can differ.
Which 2026 federal brackets are used?
The calculator uses IRS 2026 ordinary-income tax schedules for single, married filing jointly and head-of-household scenarios.
What Social Security wage base is used?
The modeled 2026 employee Social Security tax is 6.2% up to $184,500 of wages.
Are credits included?

Why might my pay stub be different?
Payroll can include state and local tax, employer benefit rules, W-4 adjustments, bonuses, garnishments, plan limits and rounding that are not modeled here.

Terms Used in This Calculator

Gross IncomeGross income is the total amount of money you earn before any deductions, taxes, or withholdings are subtracted. For employees, it includes wages, salaries, bonuses, and tips. For tax purposes, the IRS defines gross income as all income from any source, including wages, interest, dividends, rental income, and business profits.Net IncomeNet income is the amount of money you actually receive after all deductions are subtracted from your gross income. For employees, net income (also called take-home pay) is your paycheck amount after federal and state taxes, Social Security, Medicare, retirement contributions, and benefit premiums are withheld.Adjusted Gross Income (AGI)Adjusted gross income (AGI) is your total gross income minus specific above-the-line deductions such as retirement contributions, student loan interest, and HSA contributions. AGI appears on line 11 of IRS Form 1040 and determines your eligibility for many tax credits, deductions, and other tax benefits.Marginal Tax RateYour marginal tax rate is the percentage of tax applied to your last dollar of taxable income. In the U.S. progressive tax system, income is taxed in layers, and the marginal rate is the rate on the highest layer. It is always higher than your effective (average) tax rate because lower rates apply to earlier dollars of income.Tax BracketA tax bracket is a range of taxable income that is taxed at a specific marginal rate. The U.S. uses a progressive system with seven brackets ranging from 10% to 37%. Only the income within each bracket is taxed at that bracket's rate, not your entire income. Your effective tax rate is always lower than your top marginal rate.
