Payroll & Tax Calculators

Common deductions include federal income-tax withholding, state or local withholding where applicable, Social Security, Medicare, and employee benefit contributions. A benefit can reduce federal income-tax wages, FICA wages, state wages, all three, or none; the treatment depends on the plan and jurisdiction.

For 2025, employees generally pay Social Security tax at 6.2% on covered wages up to $176,100 and Medicare tax at 1.45% on covered wages without that cap. Employers begin withholding an additional 0.9% Medicare tax after paying an employee more than $200,000 in calendar-year Medicare wages; final liability thresholds depend on filing status.

These tools estimate annual tax liability and divide it by the selected pay frequency; they do not reproduce an employer's W-4 payroll engine. Benefits, local taxes, payroll timing, credits, extra withholding, garnishments, and supplemental-wage methods can all change a pay stub.

Use the IRS Tax Withholding Estimator and submit a new Form W-4 when appropriate. Eligible traditional retirement or benefit elections may change taxable wages, but reducing withholding alone does not reduce final tax liability and underpayment can trigger a penalty.

No. For 2025, Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming do not impose a broad individual state income tax on wages. Other state or local payroll taxes can still apply.
