Taxes
Two calculators live here: an Income Tax Calculator for estimating federal liability from gross income and filing status, and a VAT Calculator covering both the forward and reverse value-added tax math used across dozens of countries. Both pull their brackets and rates from published government sources rather than rough approximations.
Calculators & Tools
Income Tax Calculator
The Income Tax Calculator estimates your federal income tax liability based on gross income, filing status, and standard deductions. It applies current IRS tax brackets to show your marginal rate, effective rate, and total tax owed. Use it to plan withholding adjustments, estimate year-end refunds, or compare the impact of different income or deduction scenarios.
VAT Calculator
The VAT Calculator computes the VAT amount, net price, and gross price for any transaction using a rate you specify. It supports both the forward calculation (net to gross) and the reverse VAT calculation (gross back to net). Use it to verify invoices, set VAT-inclusive retail prices, or separate the tax component from any VAT-inclusive total.
