About
Tax Moose calculates Canadian sales tax in both directions. Add tax to a price, or pull the tax back out of a total. Both are free, with no ads.
Built in Canada for people who deal with sales tax as part of their work: contractors, freelancers, sales reps, real estate agents, accountants, and anyone who wants a fast answer at the till.
WORKS BOTH WAYS, FREE
Enter a pre-tax amount to see GST, HST, PST, QST or RST added on. Or enter a final total to see the tax already inside it and what the price was before tax. Reverse calculation is free, not locked behind a purchase.
EVERY PROVINCE AND TERRITORY
All 13 regions with current rates, including Quebec's QST and Manitoba's RST. Your province is detected on first launch and remembered, and you can switch any time.
A REAL CALCULATOR, NOT JUST A NUMBER PAD
The keypad does addition, subtraction, multiplication and division with the running expression visible, so you can total up line items or work out quantity times price without leaving the app. Tax is calculated on the result and shown as a separate line.
FULL BREAKDOWN, READY TO SEND
See the subtotal, each tax component and the total. Tap the total to copy it. Or open the share sheet to copy a clean breakdown that pastes properly into an email, invoice or note, with no app branding attached to it.
TIP
Add a tip on top of tax when you need it. Free, and tucked out of the way when you don't.
FULL FRENCH, TPS TVQ TVH
Complete French interface with correct Quebecois terminology and proper French number formatting. The app follows your device language, and you can override it in settings. Support is available in French.
RATES YOU CAN TRUST
Rates are based on official information from canada.ca and are kept current, with the last update date shown in the app. Rate changes reach you without waiting for an app update.
PRIVATE AND OFFLINE
Everything runs on your device. No internet connection required, no account, and nothing collected about your calculations. Dark mode included, and the interface scales with your system text size settings.
PRO TOOLS, ONE PAYMENT
Unlock the business toolkit with a single one-time purchase. No subscription. Pro adds discounts applied before tax, a profit margin tool that turns cost and target margin into a selling price, itemized quotes you can label and save, and a log of recent results you can tap to restore.
Not tax advice. Verify rates with the Canada Revenue Agency and your provincial authority where accuracy matters.
