Most people who buy physical gold or silver assume the tax treatment works like a stock or a fund. You buy, you hold, you sell, and you pay capital gains. That assumption is understandable, and it is also where a lot of surprises start. Under US tax rules, physical metal is not treated as an ordinary investment. It falls into a separate category, and that category changes how your gain is taxed when you sell.
The collectibles category, in plain terms
The tax code treats certain tangible items as collectibles. Coins and bullion held as physical metal sit inside that group. The practical effect is that a long-term gain on your metal does not get the lower long-term rate that applies to most investments. Instead, a different rate applies, and it is higher. This is the single fact that catches out holders who have only ever dealt with stocks.
What this means when you sell
When you sell physical gold or silver at a profit, you first work out your gain: the sale proceeds minus your cost basis. Your cost basis is what you paid, including allowable costs of acquiring the metal. If you held the metal for more than a year, the gain is long-term. If you held it for a year or less, it is short-term and taxed as ordinary income. The difference from ordinary investments shows up in the long-term case, where the collectibles rate applies to your gain rather than the usual long-term rate.
Holding period matters more than people expect
The one-year line is not a technicality. Selling just short of a year can push a gain into ordinary income treatment, which is often worse than the collectibles rate. If you are close to the threshold and there is no pressing reason to sell, waiting can change the outcome. That is a timing decision, not a loophole, and it is worth thinking through before you agree a sale.
Basis is the number you control
The tax you owe depends heavily on your cost basis, and your basis depends on your records. Keep the purchase confirmation, the date, the quantity, and any costs tied to the acquisition. If you bought in several lots over time, track each lot separately. When you sell, you need to know which metal you are selling and what you paid for it. Without that, you are guessing at a number that drives your tax bill.
Why the category exists at all
Physical metal is treated differently because the law groups tangible collectible items together rather than treating them as financial assets. You may disagree with the logic, but the rule is the rule, and planning around it is more useful than arguing with it. Knowing the category in advance lets you decide how long to hold, how carefully to document purchases, and what to expect when you eventually sell.
None of this requires an encyclopaedic knowledge of the tax code. It requires knowing which bucket your metal falls into, keeping records that establish your basis, and being deliberate about timing. If you want the rate itself explained in detail, including how the maximum applies to your gain, the guide to the collectibles tax rate and its 28% maximum walks through it step by step. Read it before you sell, not after.
