If you’re looking for a reverse GST and PST calculator, you can set the calculator above to one of the three provinces that have PST. This will combine the GST and PST, and you can enter the amount to then reverse it out. 

If you want a reverse GST PST calculator BC only, just set the calculator above for British Columbia, and it will back out the 12% combined tax rate for the amount you enter in.

The Provincial Sales Tax (PST) applies only to three provinces in Canada. The PST is combined with GST to give the total tax for goods and services for residents of those provinces.

QST Tax Rate: 9.975%

The above calculator works as a reverse GST QST calculator also. You just set the province to Quebec, set the dollar amount you want to reverse, and the tool will do the rest. 

It’s great to have a reverse GST QST calculator because it will save you a lot of time when you’re trying to figure out how much taxes you have spent on your purchase. 

The Quebec Sales Tax (QST) is simply the sales tax applied in the province of Quebec. Why is QST 9.975%? It’s because when the government changed it back in 2003 from 9.5% to 9.975%, they wanted to keep the same level of revenue because the calculation was slightly different and was no longer charging it on amounts, including GST.

Conclusion

It can be tricky to reverse out your GST, HST, PST, and QST payments when you need them during the tax time. Thanks to the reverse tax calculator above, this is no longer a worry.
