U.S. taxes are a stack of overlapping rules: federal income tax brackets, FICA payroll taxes, state and local income tax (in most states), and a long list of credits, deductions, and special-case carve-outs. Our tax calculators are built around the current IRS tables and provide quick estimates for the calculations that come up most often in personal financial planning.

Start with the income tax estimator for a federal-only projection of your tax liability based on filing status, gross income, and standard or itemized deductions. The salary-to-hourly and hourly-to-salary converters help convert pay rates for negotiation or freelance pricing. The overtime calculator applies federal FLSA rules for time-and-a-half above 40 hours.

Specialized tax tools cover earned income credit, child tax credit, charitable giving deduction value, estate tax exposure, lottery winnings net of tax, and the self-employment quarterly tax payment schedule. The tariff impact calculator estimates how recently-imposed tariffs change landed cost on imported goods — useful for small businesses and importers.

Bracket data is kept current to the most recent IRS publication. FICA rates (Social Security 6.2% to the wage base cap, Medicare 1.45% all wages plus 0.9% additional above $200k single / $250k joint) follow the current SSA and IRS schedules. State income tax varies dramatically — these calculators are federal-only unless explicitly labeled state-specific. Tax law changes annually; we update calculators within the first quarter after the new IRS tables are published.

Results are estimates intended for planning, not for tax-return filing. Every taxpayer's situation is different — itemized deductions, AMT exposure, NIIT, retirement-account interactions, multiple state filings, and dozens of other variables can change your actual liability. For preparing returns or making significant tax-planning decisions, consult a CPA or enrolled agent.
