New Brunswick sales tax is simple and straightforward because the province employs the harmonized sales tax (HST). However, some might struggle with it due to the ever-changing laws, categorizations and exceptions. This New Brunswick tax guide 2025 will help you easily navigate all of these factors.

New Brunswick’s Sales Tax System

New Brunswick uses the Harmonized Sales Tax (HST) system, which integrates federal and provincial sales taxes into a single rate. This simplifies compliance for businesses, as they only need to register, collect, file, and remit one tax to the Canada Revenue Agency (CRA). New Brunswick HST saves businesses from dealing with separate tax systems (GST and PST).

However, businesses must stay organized, track Input Tax Credits (ITCs), and maintain proper records to avoid penalties. While it’s simpler than dual-tax provinces, it still requires diligent administration and compliance.

What is New Brunswick’s HST?

HST New Brunswick combines both federal (5%) and provincial (10%) sales taxes into a single 15% rate. NB HST applies to most tangible goods sold in-store or online. It is also charged on food and beverage services, digital products, and professional and personal services.

Exempt items, on the other hand, are not subject to New Brunswick tax. Also, businesses cannot claim ITCs for costs related to these sales. Exempt-items include residential rent, child care services, and financial services.

Calculate Your New Brunswick Sales Tax

Calculating sales tax in New Brunswick is straightforward thanks to the NB HST system, which combines both federal and provincial taxes into a single 15% rate. This section will help you calculate New Brunswick sales tax step by step. Whether you’re adding New Brunswick sales tax (HST) to a sale or working backward from a total that includes tax, we will guide you.

Step-by-Step Calculation for NB HST

For example, you’re selling a desk in New Brunswick for $500. You need to calculate the 15% NB HST and determine the total price after taxes the customer must pay.

Step 1: Determine the NB HST Rate

New Brunswick HST = 15%

As a decimal: 0.15

Step 2: Use the Formula to Calculate New Brunswick HST

Sale Price = $500

New Brunswick HST Amount = Sale Price x HST Rate

New Brunswick HST Amount = $500 x 0.15

New Brunswick HST Amount = $75.00

Step 3: Add New Brunswick HST Amount to the Sale Price

Total Price = Sale Price + New Brunswick HST Amount

Total Price = $500 + $75

Total Price = $575.00

If, for instance, you receive a total invoice of $575.00 for a desk purchase in New Brunswick, and you want to find out the pre-tax price and the NB HST. Use the formula below.

Step 1: Know the NB HST rate

NB HST = 15%

NB HST (total multiplier) = 1.15

Step 2: Use the formula to find the pre-tax price

Total Price = $575.00

Pre-Tax Price = Total Price/NB HST (total multiplier)

Pre-Tax Price = $575.00/1.15

Pre-Tax Price = $500.00

Step 3: Subtract to find the NB HST amount

NB HST Amount = Total Price - Pre-Tax Price

NB HST Amount = $575.00 - $500.00

NB HST Amount = $75.00
