New Brunswick HST Calculator
New Brunswick uses a single 15% Harmonized Sales Tax (HST). Add the 15% HST to a price, or pull it back out of a tax-included total — one rate, one tax.
Flat-rate estimate. Some goods and services are zero-rated or exempt, and PST/RST have their own exemptions — your actual invoice can differ.

How sales tax works here
New Brunswick is an HST province: the 5% federal GST and a 10% provincial part are combined into a single 15% HST that the CRA administers. You charge one rate and file one GST/HST return — there's no separate provincial sales tax to track.
You generally register once taxable sales pass $30,000. Basic groceries and many health and financial services are zero-rated or exempt, so a real invoice can differ from a flat 15%.
FAQ
No — the provincial part is built into the 15% HST, which the CRA administers. There's no separate PST to register for or file.
Generally once your taxable sales pass $30,000 — measured over a single calendar quarter or the last four consecutive quarters. Under that you're a "small supplier" and registering is optional. The $30,000 counts your worldwide taxable sales and those of anyone you're associated with, not your profit.
Switch the calculator to "Take GST/HST out of a total" and enter the tax-included amount. It divides by one plus the combined rate to find the price before tax, then shows the tax on top.
