When Is Bullion GST/HST-Exempt in Canada? (And When It Isn't)

Two silver pieces, same shop, same afternoon. One rings up with tax. The other doesn't. It isn't a mistake at the till, and it isn't random: in Canada, qualifying investment-grade bullion is exempt from GST/HST, treated more like a financial instrument than a thing you buy. But "bullion" isn't the test. There's a specific line a piece has to cross, and plenty of metal everyone calls bullion lands on the wrong side of it.

Knowing where that line sits does two things. It tells you whether a given piece carries a tax line at all, and because tax is part of what you actually pay, it's part of comparing one buy against another.

One important caveat before the details: we're not tax specialists, this isn't tax advice, and the goal here is to teach you the question to ask, not to rule on your specific coin. More on the limits at the end.

The qualifying line

Under the Excise Tax Act, the exemption applies to a "precious metal" in a specific sense: a bar, ingot, coin, or wafer of gold, platinum, or silver, at or above a minimum purity. The purities are exact, and worth getting right, because some sources state them wrong:

- Gold: 99.5% or higher - Platinum: 99.5% or higher - Silver: 99.9% or higher

If you've seen a page say gold needs to be 99.9%, that's incorrect. Gold and platinum qualify at 99.5%. Only silver needs 99.9%.

Purity matters, but it isn't the whole test, because form matters too. The metal has to be in a recognized investment form: a coin, bar, ingot, or wafer. For coins, that generally means government-issued legal tender. For bars, ingots, and wafers, it means recognized purity markings plus an issuer or refiner mark. A generic, unmarked private round is greyer than "it's .999, so it's fine," because the form and the markings are part of what qualifies a piece, not just the metal content.

So the real test is three things at once: the right metal, at the right purity, in the right form.

The coin that surprises everyone

The cleanest way to see why "it's famous bullion" isn't the test is the American Gold Eagle. It's one of the most recognized bullion coins in the world, and it does not qualify. Gold Eagles are 22-karat, about 91.67% gold, which is below the 99.5% line. Famous, widely traded, unmistakably a "bullion coin," and taxable in Canada anyway.

If a coin that well-known can miss the line, the lesson writes itself: check the purity, don't assume from the reputation.

A few other things people are sometimes surprised to find on the taxable side:

- Sterling silver is 92.5%, below the 99.9% silver line, so it doesn't qualify. - Carat-gold jewellery, and anything in jewellery or other chattel form, falls outside the investment-form requirement. - Palladium isn't in the exempt definition at all. The exemption covers gold, platinum, and silver. Palladium, whatever its purity, simply isn't on the list.

Why this belongs in your all-in math

This blog keeps circling one idea: the number that matters is what you actually pay, all-in, not the sticker or the hammer. The tax exemption is a piece of that. A qualifying piece has no GST/HST line. A non-qualifying one adds it on top, plus any provincial sales tax that applies where you are (provincial treatment is its own question and varies by province, so check yours).

That can change a comparison. Two lots that look similar on metal can land differently once one carries a tax line and the other doesn't. So "does this qualify?" isn't trivia. It's part of working out which buy is genuinely cheaper.

One thing it is not: an app feature. The app does the metal and auction math. It doesn't calculate your tax. Whether a tax line belongs in your all-in comes down to this qualifying test, and that part is on you to know.

Two things this post is not

First, this is about sales tax (GST/HST) at the time you buy. It is not about capital gains. If you sell bullion later for more than you paid, capital gains can still apply. "Exempt from GST/HST at purchase" does not mean "tax-free forever." Keep the two separate, so a sales-tax exemption doesn't lull you into forgetting the other side.

Second, plainly: we're not tax specialists, and this isn't tax advice. The rules can change, the line can be genuinely grey for some pieces (private rounds, unusual forms, edge-case purities), and the only authority on your specific item is the Canada Revenue Agency, or a tax professional looking at the actual piece. Treat this as the question to ask, then verify the answer for what you're actually buying.

The short version: don't ask "is it bullion?" Ask "is it the right metal, at the right purity, in the right form, and government-issued if it's a coin?" That's the line, and it's the part of your all-in cost that nobody rings up for you.
