Tax & Payroll

Tax and payroll calculators estimate how much of a paycheck, raise or payout you keep, and what you may owe. Start with the income tax calculator, the salary tax calculator and the quarterly estimated tax calculator.

Payroll tools cover overtime tax, shift differentials, time cards, PTO payouts, severance pay, final paychecks and workers' comp settlements, plus a UK salary increase calculator. Tax tools cover the marriage tax comparison, estate tax, sales tax, VAT and business mileage, and the COBRA cost calculator estimates continuation premiums. Pages that rely on published rates name the tax year and link to the official source.

All results are simplified planning estimates, not tax advice. Withholding, credits and state or local rules can change the final figure, so compare results with your pay stub or a tax professional. Background guides include how salary tax withholding works and how overtime is taxed.
