New Brunswick uses a 15% HST on a standard taxable supply. It is one combined tax, rather than GST plus a separate provincial sales tax. CRA’s rate guidance is the current federal source for the GST/HST rate and explains that the rate depends on the place and type of supply.
The standard rate
| Component | Rate |
|---|---|
| HST | 15% |
For a $100 taxable sale at the standard rate, calculate tax from the pre-tax amount. A rate is not a tax-classification decision: zero-rated and exempt supplies, and special rules, can produce a different result.
What to show on an invoice
For a taxable GST/HST sale, tell the customer whether tax is included or added. Show the applicable rate and either the tax amount or a clear tax-included statement. If HST applies, CRA says to show the total HST rate rather than separate federal and provincial components. CRA’s invoice guidance has the rule.
Sales across provincial borders
A business address alone does not set the rate. The place-of-supply rules and the kind of supply matter. CRA’s examples show that delivery or other supply facts can change the province whose rate applies. Check place-of-supply guidance before applying a rate to a cross-province sale.
Local rules to check
New Brunswick lists HST among its provincial tax topics. CRA administers the GST/HST system; use CRA guidance for federal registration and return obligations.
