Buy a $30,000 vehicle from a dealer in New Brunswick and tax adds $4,500, so the deal is $34,500 before licensing and registration. Buy the same car privately and New Brunswick charges 15% when you register it, which is $4,500 on that price. Drive the same purchase across the border into Ontario and the tax is $3,900, which is $600 less.

One gap is forgiven: where the price is below the average wholesale value by $1,000 or less, the price itself is the fair value. The floor for a motor vehicle is $1,000.

Open the calculatorA dealer sale carries 15% HST: 5% federal and 10% New Brunswick. On a $30,000 vehicle that is $4,500, for $34,500 all in before licensing.
A private purchase carries the 15% provincial vehicle tax instead, collected by Service New Brunswick at registration.

Where a dealer takes your old vehicle in trade, the tax is charged on the difference: the trade-in credit comes off the price before GST or HST is applied. That is a federal rule, so it holds everywhere in Canada.
Every market figure the calculator itself uses is listed with its source on the assumptions page.
