Two questions every business owner asks monthly: how much tax to add to a quote, and how much tax was already inside a total. This does both, per province.
Adding versus extracting
Adding is multiplication by the rate. Extracting is division: a $1,130 Ontario invoice that already includes HST carries $130 of tax ($1,130 ÷ 1.13 × 0.13), not $146.90. The extract mode exists because the second mistake — computing tax on a tax-inclusive total — is the most common bookkeeping error in small-business Canada.
Frequently asked questions
When must I register for GST/HST?
Once your worldwide taxable revenues exceed $30,000 in four consecutive quarters — or immediately if you expect to cross it. Below that, registration is optional but lets you claim input credits.
