A $200 item in Quebec costs $229.95 once the 5% GST and the 9.975% QST are added: $10.00 of GST and $19.95 of QST. Enter a price, say whether tax is already in it, and this GST QST calculator shows both amounts. Together the two taxes add 14.975% to most things you buy.
What are TPS and TVQ?
Quebec receipts often print the French names. TPS, for taxe sur les produits et services, is the federal tax, and TVQ, for taxe de vente du Quebec, is the provincial one. They’re the same GST and QST this page uses. If a Montreal store prints “TPS 5%” and “TVQ 9.975%”, you’re looking at exactly the two lines the calculator gives you, and the CRA’s GST/HST calculator and rates page lists Quebec at the same 5% and 9.975%.
What do the two taxes add up to on common prices?
On a $50 shop the tax is a few bucks, $7.49 to be exact, so the till says $57.49. Here’s the pattern at a few other prices.
| Price before tax | GST (TPS) 5% | QST (TVQ) 9.975% | Total |
|---|---|---|---|
| $50 | $2.50 | $4.99 | $57.49 |
| $100 | $5.00 | $9.98 | $114.98 |
| $200 | $10.00 | $19.95 | $229.95 |
| $1,000 | $50.00 | $99.75 | $1,149.75 |
Is the QST charged on the price plus GST?
No. The QST is worked out on the price before GST, and the note under the calculator’s result says so. Plenty of shoppers assume the second tax lands on the price plus the first. If it did, the QST on $100 would be $10.47. Here it’s $9.98, and the combined rate of 14.975% is a plain sum of the two.
Since both taxes share the same base, taking them out is one division. Divide the total by 1.14975 and you have the price before tax.
How do I pull the tax out of a bill?
Say a Quebec invoice reads $1,000 with tax included. Choose “already includes TPS and TVQ” and the price before tax is $869.75. Inside the total sit $43.49 of GST and $86.76 of QST, so the tax comes to $130.25. Try $1,149.75 as well and you get a clean $1,000 back, with $50.00 of GST and $99.75 of QST.
Now picture Marie-Eve, a freelance translator in Montreal, who bills a client $1,200 before tax. GST is $60.00 and QST is $119.70, so the client pays $1,379.70. Her bookkeeping will want the two amounts on separate lines, and working backwards from $1,379.70 gets her to $1,200.00 again.
Two slips come up all the time. One is adding 14.975% to a price that already has tax in it, which overstates the bill by about 15%, so pick the “already includes” option instead. The other is adding the second tax on top of the first, as in the $10.47 trap above.
Your till may show a figure a cent away from ours. A store rounds each line, while this page rounds once on the total.
What isn’t taxed in Quebec?
The calculator taxes the whole amount you type in, but Quebec doesn’t tax everything. According to the note in the calculator, basic groceries, most medical services and some other items carry no tax. If a bill mixes taxable and untaxed lines, split it first and run only the taxable part through. A $450 repair bill sitting beside $45 of basic groceries, for example, means entering $450, which carries about $67.39 of tax.
Buying outside the province? Use the GST and HST calculator. And if you’re holding a total with tax already inside, the reverse HST calculator covers every province in one place.
Anyone selling across provinces can compare Quebec with the western setup on the GST and PST calculator, where the provincial tax is 6% or 7%.
What this page is based on
The 5% GST and the 9.975% QST match the federal rate table linked above. For the QST rules themselves, Revenu Quebec is the body that collects it, so check there before you rely on a rate for a large purchase. This is an independent guide, separate from any government body.
