In New Brunswick, a single tax is added to the price of most goods and services: the Harmonized Sales Tax (HST) at a rate of 15%. It combines the federal portion (5%) and the provincial portion (10%) into a single tax and is administered by the Canada Revenue Agency (CRA). There is no separate provincial sales tax to add. Understanding how it works is essential for billing correctly and, where applicable, recovering the tax paid on your business purchases through ITCs.
The principle is simple: the HST is applied as a percentage of the pre-tax subtotal. In New Brunswick, a single rate of 15% is added to the pre-tax price to calculate the total amount due. Since the HST is a single tax, you don’t have to add a separate federal and provincial portion: the calculator uses the exact rate and applies it automatically, which prevents rounding errors in your billing.
A taxable sale (in most cases) is charged at a 15% HST rate. A zero-rated sale is charged at 0%, but the business can generally recover the tax paid on related purchases. An exempt sale is not subject to any tax, and the business cannot recover the tax paid on related inputs. The exact categories (basic food, health, exports, financial services) are defined by the CRA.

In New Brunswick, the HST is 15% (5% federal + 10% provincial), administered by the CRA. Rates effective in 2026, source: Canada Revenue Agency.
In New Brunswick, only one tax applies: the Harmonized Sales Tax (HST) at a rate of 15%. It combines the federal portion (5%) and the provincial portion (10%) into a single tax, administered by the CRA. There is no separate provincial sales tax to add. Certain categories of goods may be zero-rated or exempt.
Enter your total amount (including tax) and specify that the tax is already included: the tool calculates the subtotal excluding tax by dividing by 1.15 (the 15% HST combined rate), then displays the HST separately. Our calculator performs this calculation automatically.
In New Brunswick, the requirement to register for and collect the HST applies as soon as your taxable sales exceed the $30,000 threshold. Once registered, the business charges the HST to its customers, files periodic returns, and remits the net tax to the CRA. An accountant can confirm your obligations based on your business activity.
HST registration becomes mandatory once taxable sales exceed $30,000 over four consecutive quarters (below this threshold, the business is considered a small supplier). Below this threshold, the business generally does not charge the tax, but also cannot recover the tax paid on its purchases. Voluntary registration remains an option to recover these taxes.
A registered business can deduct the HST it paid on its business expenses from the HST it collected on its sales, and then remit the difference to the CRA (or receive a refund if the difference is negative). These are ITCs, which are available in New Brunswick as well as everywhere else where the HST applies.
