PrePostTax

Know before you pay. PrePostTax is a fast, easy-to-use sales tax calculator built to help estimate sales taxes across Canada's GST, HST, PST, and QST systems.

PRICE CHECK

Enter an item's price and your province or territory to view an estimated tax breakdown, including federal GST, provincial tax, total tax, and the estimated total amount payable. Tax calculations are based on publicly available tax rates for each Canadian province and territory.

REVERSE TAX

Already have a receipt? Enter the tax-inclusive total and PrePostTax estimates the pre-tax price and tax amounts based on the selected province or territory. Useful for expense reports, reimbursements, and verifying receipts.

INDIGENOUS TAX EXEMPTION

Toggle Indigenous Status to estimate tax exemptions where applicable based on the selected province or territory.

MY CLAIMS

Save reverse-tax calculations as claims, including receipt photos, store name, and purchase date. Keep a personal record for expense tracking or future reference.

PRINT & EMAIL REPORTS

Generate a PDF report of your saved claims, including receipt photos, and print or share it using your preferred apps.

PRIVATE BY DESIGN

PrePostTax has no accounts, no sign-up, and no server. Everything you enter—including prices, provinces, claims, and receipt photos—remains on your device. Nothing is uploaded or shared.
