Understanding New Brunswick Taxes
New Brunswick charges a single harmonized rate of 15.00% on most goods and services.
New Brunswick has used the Harmonized Sales Tax since 1997, one of the original three Atlantic provinces (with Newfoundland and Nova Scotia) to adopt HST.
On the income tax side, New Brunswick's provincial brackets start at 9.4% and rise to 19.5% for the top bracket, layered on top of the federal brackets (14% to 33% for 2026).

Why Reverse Sales Tax Calculation Matters
Receipts and invoices usually show only the tax-included total, so separating revenue from GST/HST or PST collected — for bookkeeping or cross-province price comparisons — means working backward from that total. Dividing by (1 + rate) isn't the same as subtracting the rate, which is why the calculator above handles it exactly.
History & How the Rate Is Built
New Brunswick was one of the original three Atlantic provinces — alongside Nova Scotia and Newfoundland and Labrador — to adopt the Harmonized Sales Tax on April 1, 1997, following federal-provincial agreements signed in October 1996 that folded the provincial sales tax into a single federally administered rate.
As an HST province, New Brunswick's combined 15% rate flows through a single federal collection mechanism, with the province's HST share remitted back by the federal government — simplifying administration compared to separate-PST provinces like BC or Manitoba.
Business Use Case: Registering in New Brunswick
A retailer registering for GST/HST purposes in New Brunswick automatically collects and remits the full 15% HST under one registration — there's no separate provincial sales tax step, unlike BC, Manitoba, or Saskatchewan.
Real-World Example
A $100.00 purchase in New Brunswick at the combined rate of 15.00%:
- Tax amount: $100.00 × 15.00% = $15.00
- Total price: $100.00 + $15.00 = $115.00
New Brunswick Tax Registration for Businesses
As an HST province, New Brunswick uses the same $30,000 national small-supplier threshold as GST — there is no separate provincial registration step.
