Updated Checked by the Tax-Services.ca editorial team How we check
A tax converter turns a number with tax in it into one without, or the other way round. We’re assuming that’s what you’re after, and not a currency tool. For a price, divide by 1.13 to strip Ontario’s 13% HST, so $113 becomes $100. For pay, the answer depends on your province, and $4,000 a month after tax takes about $60,373 a year before tax in BC.
How do you convert a price with tax back to the price before tax?
Divide by one plus the rate. Don’t subtract the percentage, because the tax was added to the price, not taken from the total. Take 13% off $113 and you get $98.31. That’s wrong by $1.69.
The reverse HST calculator does the division and splits out the tax. In Alberta, $105 is $100 plus $5 GST. In Nova Scotia, $114 is $100 plus $14 HST. For Quebec, GST and QST together make 14.975%, so $114.98 works back to $100.
A small example: a double-double at an Ontario drive-thru rings in at $2.26 with HST. Divide by 1.13 and the coffee itself is $2.00, with $0.26 of tax.
Rates depend on where the sale is made. The CRA’s page on which GST/HST rate to charge explains that the rate depends on the province or territory, and it confirms Nova Scotia’s HST is 14%. The table shows the rates our calculators use.
| Province or territory | GST or HST | PST |
|---|---|---|
| Alberta, Northwest Territories, Nunavut, Yukon | 5% | None |
| British Columbia | 5% | 7% |
| Manitoba | 5% | 7% |
| Saskatchewan | 5% | 6% |
| Quebec | 5% | 9.975% (QST) |
| Ontario | 13% HST | None |
| Nova Scotia | 14% HST (from April 1, 2025) | None |
| New Brunswick, Newfoundland and Labrador, Prince Edward Island | 15% HST | None |
Is there a shortcut for working it out in your head?
There is. The tax inside a total is the rate divided by one plus the rate. In Ontario that’s 13 over 113, or about 11.5% of the total. In the Atlantic provinces with 15% HST it’s 15 over 115, about 13%, and in Nova Scotia 14 over 114, about 12.3%. Where only the 5% GST applies, it’s 5 over 105, about 4.8%. So a $60 receipt in Alberta holds roughly $2.86 of GST. It’s a ballpark, good enough to check a bill, not to file with.
Why doesn’t a flat rate always work?
Because not every item carries tax, and not every item carries the full rate. Some things are exempt or zero-rated, and where a province has its own PST, the two taxes may not apply to the same things. The GST and PST calculator applies the full combined rate in BC to whatever you enter, so it can overstate the tax on an item that has no PST. Check the receipt for the item that matters to you.
How do you convert take-home pay to a gross salary?
This is the harder one, since income tax rises in steps and you can’t just add a percentage. Our net to gross calculator tries salaries until the take-home matches. Say you need $4,000 a month after deductions.
| Where you work | Salary needed | Income tax | CPP and EI |
|---|---|---|---|
| Alberta | $60,471 | $8,096 | $4,375 |
| British Columbia | $60,373 | $8,005 | $4,368 |
| Ontario | $61,027 | $8,609 | $4,418 |
So Ontario needs about $654 more a year than BC for the same $48,000, and BC needs $98 less than Alberta. Small gaps. These use the basic personal amount and the CPP and EI credits only, so any other credit or deduction you have will pull the salary needed down.
What about hourly wage to yearly pay?
People mix this up with tax conversion constantly. It isn’t tax at all, until you ask what’s left. Enter $28 an hour in the hourly to salary calculator and the defaults give $58,240 a year, at 40 hours over 52 weeks. After deductions in Ontario that’s $46,154 a year, or $22.19 an hour. Overtime isn’t counted.
Where does a conversion go wrong?
Three spots. Rounding: a receipt can differ from the calculator by a cent. Bundled items: a bill mixing taxable and exempt goods can’t be converted with one rate. And the year: rates change, and payroll figures here are for 2026. Nova Scotia’s HST dropped from 15% to 14% in April 2025, and any older price list still in your head could use the old rate.
Also check whether a quoted price includes tax at all. Online listings and contractor quotes in Canada often show the price before tax, while a shelf tag in a store usually does too, so the number at the till is higher. Ask which one you’re looking at before you compare two offers.
Before you rely on any converted figure for a decision, such as a job offer quoted before tax or a quote you’re comparing across provinces, run it both ways and check that you land back where you started. If you don’t, one input is off.

Frequently asked questions
How do I remove 13% HST from a price?
Divide by 1.13. A $113 price is $100 plus $13 of HST. Subtracting 13% of $113 would give the wrong answer.
What is the GST and QST rate in Quebec together?
The CRA lists 5% GST and 9.975% QST, so 14.975% combined. A $114.98 price works back to $100.
How much salary gives $4,000 a month after tax?
About $60,373 in BC, $60,471 in Alberta and $61,027 in Ontario in 2026, counting only the basic personal amount and CPP and EI credits.
Why can a BC tax tool overstate tax?
Our GST and PST calculator applies the full 12% to what you enter. Items without PST would carry less, so check the receipt.
Is $28 an hour the same as $58,240 a year?
Yes at 40 hours a week for 52 weeks, before deductions. After tax in Ontario it's about $46,154.
