About TaxesLedger
Free, accurate, ad-supported sales tax tools for everyone — no signup, no friction.
What we do
TaxesLedger is a suite of eleven free calculators covering US sales tax (forward, reverse, by-state, multi-state, reconciliation, holidays, tip & tax) plus VAT for Europe and GST/HST for Canada. Every tool shows its math like a clean receipt so you can audit each step.
Why we built it
Most existing sales tax calculators do the math but never explain it. We wanted a single home for accurate, transparent tax tools — built to a higher design standard than the industry norm — accessible to consumers, small business owners, and the accountants who keep their books clean.
Where our rates come from
US state rates are sourced from the Tax Foundation and verified against individual state Department of Revenue publications. Canadian rates come from the Canada Revenue Agency. EU VAT rates come from the European Commission's official VAT database. We refresh quarterly.
