01

Sales tax in New Brunswick

New Brunswick charges a single Harmonized Sales Tax of 15 percent, which combines the 5 percent federal GST with a 10 percent provincial portion. It is one of four Atlantic-region provinces that use HST.

Because HST is harmonized, you charge one tax line and the federal agency administers it, so there is no separate provincial registration to manage as there is in PST provinces.
