The Internal Revenue Service classifies physical gold, silver, platinum and palladium as "collectibles" under IRS Publication 544. This classification matters because collectibles receive different capital gains treatment than stocks, bonds or real estate.
When you sell precious metals at a profit after holding them for more than one year, the gain is taxed at the collectibles capital gains rate of up to 28%. This is higher than the standard long-term capital gains rate of 15% or 20% that applies to most other investment assets. If your marginal income tax rate is below 28%, you pay your marginal rate instead. The 28% rate functions as a cap, not a floor.
Short-term gains on metals held less than one year are taxed at your ordinary income tax rate, just like any other short-term capital gain. For high-income earners in the 37% federal bracket, this creates a meaningful incentive to hold metals for at least one year before selling.
Losses on precious metals sales are deductible against capital gains. If you sell silver at a loss, that loss can offset gains from other investments including stocks and real estate. Net capital losses up to $3,000 per year can be deducted against ordinary income, with excess losses carried forward to future tax years.
