GST/HST Quick Method Calculator — Canada 2026
What is the GST Quick Method?
The Quick Method is a CRA-approved way to calculate your GST/HST remittance without tracking every expense. Instead of adding up all the GST you paid on business purchases and subtracting it from what you collected, you just multiply your total revenue (including GST/HST) by a flat rate. You remit that amount. Done.
You still charge your customers the full GST or HST rate. The Quick Method only changes what you send to CRA — not what your customers pay.
Most sole proprietors, freelancers, side hustlers, and small business owners with under $400,000 in annual revenue qualify. The main exceptions are accountants, bookkeepers, lawyers, financial advisors, and actuaries — they must use the regular method.
The rate depends on two things: your province (which determines what tax rate applies) and your business type (service vs. product seller). Use the calculator below to get your number.

Enter the amount you invoiced or earned, not including the tax you charged on top.
Not sure? If most of what you do is a service, pick Option A.
CRA gives you a 1% credit on the first $30,000 of revenue each fiscal year — worth up to $300. Uncheck if you've already claimed this for the year.
What to do with this number
To use the Quick Method, you first need to file an election with CRA using Form GST74. You must do this before the start of the reporting period you want it to apply to. You can file it online through My Business Account on the CRA website.
Once elected, you remit the amount calculated above each reporting period (monthly, quarterly, or annually depending on your registration). The election stays in effect for at least one year — you can't switch back immediately.
A note for marketplace sellers: If you sell on eBay or Amazon, the marketplace already remits GST/HST on your behalf for those sales — you don't remit separately for them. If you sell on Etsy and have added your GST number to your Etsy account, Etsy stops remitting on your behalf and you remit directly. In that case, your Etsy revenue counts toward this calculation.
