The GLDM tax treatment follows the rules for collectibles rather than the rules for ordinary stock: long-term gains on SPDR Gold MiniShares are taxed at a federal rate of up to 28%, short-term gains are taxed at your ordinary income rate of up to 37%, and the trust quietly generates small taxable events each year by selling gold to cover its own expenses. That last piece catches most investors off guard, because it produces a tax bill and a cost-basis adjustment even in years you never place a trade.
Why the Collectibles Rate Applies
GLDM is organized as a grantor trust. The fund itself pays no tax; income, expenses, gains, and losses pass through to shareholders as if each investor owned a proportional slice of the physical gold in the vault.1U.S. Securities and Exchange Commission. SPDR Gold MiniShares Trust Annual Report (Form 10-K) A GLDM share is not stock in a company. It is an interest in bullion.
Federal tax law puts gold in the same category as art, antiques, rare coins, and gems.2Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts The code defines collectibles gain with reference to metals and gems and specifies that the narrow exception for bullion held by a qualifying trustee does not carry over for capital gains rate purposes.3Office of the Law Revision Counsel. 26 USC 1 – Tax Imposed The result: even though GLDM trades on the NYSE like any other ETF, your shares inherit the collectible classification from the metal behind them.
Short-Term Gains
Sell GLDM within a year of buying and any profit is a short-term capital gain, added to your other income and taxed at your ordinary rate.4Internal Revenue Service. Topic No. 409, Capital Gains and Losses Federal brackets for 2026 range from 10% to 37%.5Internal Revenue Service. Federal Income Tax Rates and Brackets No collectibles surcharge, no special worksheet. It is the same treatment any other short-held investment would get.
Long-Term Gains and the 28% Ceiling
Hold GLDM for more than a year, and the collectible classification changes the math. Instead of the 15% or 20% long-term rate that applies to most stocks, gains face a maximum federal rate of 28%.6U.S. Securities and Exchange Commission. SPDR Gold MiniShares Trust Registration Statement (Form S-1/A) GLDM’s prospectus states this directly: gain from selling shares held for more than a year, along with gain from the trust’s own gold sales attributed to a shareholder, is taxed at the 28% collectibles rate.
The 28% figure is a ceiling, not a flat rate. If your taxable income places you in a lower bracket, you pay that lower rate on the gain instead.3Office of the Law Revision Counsel. 26 USC 1 – Tax Imposed A single filer sitting in the 22% bracket pays 22% on the collectibles gain. The 28% cap only starts saving money once your ordinary rate would otherwise exceed it, at roughly the 32% bracket and above.
Net Investment Income Tax
Higher earners owe another 3.8% on top of the capital gains rate through the Net Investment Income Tax, which applies once modified adjusted gross income exceeds $200,000 for single filers or $250,000 for joint filers.7Internal Revenue Service. Net Investment Income Tax Those thresholds have not been indexed for inflation since the tax took effect in 2013. Stack NIIT on a maxed-out collectibles rate and the combined federal bite reaches 31.8%.
The Tax You Owe Even If You Never Sell
GLDM charges a sponsor fee of 0.10% per year, calculated daily against net asset value.8U.S. Securities and Exchange Commission. SPDR Gold MiniShares Trust Notes to Financial Statements The trust has no cash account. To pay the fee, it sells small amounts of gold throughout the year.
Because GLDM is a grantor trust, the IRS treats those sales as if you personally sold a sliver of your own gold.1U.S. Securities and Exchange Commission. SPDR Gold MiniShares Trust Annual Report (Form 10-K) Each transaction produces a tiny gain or loss based on the difference between the allocated basis and the price on the day the trust sold. Over a year, these add up to a small but real tax obligation, even if you are holding for the long run.
Two consequences follow. You owe tax on gains you never received in cash. And your cost basis in the remaining shares gradually shrinks, because after each expense sale the trust holds slightly less gold per share. When you eventually sell, that lower basis means a larger reported gain. Skip the adjustment and you overpay on the final sale, since brokers typically do not update basis for these internal sales.
Reporting GLDM on Your Return
Your brokerage will send a Form 1099-B showing proceeds from any shares you sold during the year.9Internal Revenue Service. About Form 1099-B, Proceeds from Broker and Barter Exchange Transactions That form usually does not capture the trust’s internal gold sales and will not adjust your cost basis for them. Most reporting mistakes start here.
To close the gap, use the annual tax information the trust’s administrator publishes. That document lays out your allocable share of gold sales, expenses, and basis adjustments for each period. It is available through the SPDR Gold Shares website and often through your brokerage’s tax document portal. Without it, you are guessing at your true basis.
Reporting itself goes on Schedule D of Form 1040.10Internal Revenue Service. About Schedule D (Form 1040), Capital Gains and Losses Long-term GLDM gains are reported as 28% rate gains. The Schedule D instructions include a 28% Rate Gain Worksheet for collectibles, and the result goes on line 18 of the schedule.11Internal Revenue Service. Instructions for Schedule D (Form 1040) The trust’s expense-related gold sales are reported on Form 8949 alongside any share sales you made yourself.
GLDM Inside an IRA or 401(k)
A retirement account seems like the obvious way to sidestep the 28% rate, but the collectibles rules create a possible trap. When an IRA acquires a collectible, the purchase amount is treated as a taxable distribution to the account holder.2Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts Metals and gems are on the list. There is an exception for gold bullion of sufficient fineness, but only when the bullion is in the physical possession of the IRA’s own trustee.
GLDM does not fit that exception. Its gold is held by the trust’s custodian, not by your IRA custodian. On the statute’s face, buying GLDM shares in an IRA looks like acquiring a collectible, which would trigger a deemed distribution equal to the purchase price. In practice, most brokerages allow the purchase without flagging any issue, and the IRS has not issued public guidance on whether grantor trust gold ETF shares count as a collectible for this purpose. The gap between statutory text and everyday brokerage practice is real. A significant GLDM position inside a retirement account is worth walking through with a tax professional.
Wash Sales and GLDM
Sell GLDM at a loss and buy it back within 30 days, and the wash sale question surfaces. The federal wash sale rule disallows losses on sales of stock or securities when a substantially identical investment is repurchased in that window. Because the IRS classifies gold ETF shares as interests in a collectible rather than as securities for capital gains purposes, some practitioners argue that grantor trust gold ETFs fall outside the wash sale rule. The logic: the same shares cannot be treated as collectibles for the 28% rate and as securities for wash sale purposes.
This reading is not settled, and the IRS has not published guidance specifically on wash sales for grantor trust gold ETFs. If the rule does not apply, you can harvest a GLDM loss and immediately buy back in without losing the deduction. A more cautious approach is to wait the 30 days or switch temporarily to a different gold ETF.
How GLDM Compares to Other Gold Investments
The 28% collectibles rate applies to investments that give direct or pass-through exposure to physical gold, which includes GLDM, GLD, IAU, and similar grantor trust gold ETFs. Other gold vehicles carry different tax profiles.
- Gold mining stock ETFs, such as GDX or GDXJ, hold shares of mining companies and are taxed as ordinary equities. Long-term gains qualify for the standard 15% or 20% rate, and short-term gains follow ordinary income rates. No collectibles surcharge applies because you own corporate stock, not metal.
- Gold futures ETFs generally fall under the 60/40 rule: 60% of gains are treated as long-term and 40% as short-term regardless of holding period. The blended result can come in below the 28% ceiling.
- Physical gold you hold yourself, whether coins, bars, or bullion in a safe deposit box, is taxed at the same 28% collectibles ceiling as GLDM, without the yearly basis erosion from trust expense sales. You give up the convenience of exchange trading.
Within the physical gold ETF category, GLDM’s 0.10% expense ratio is among the lowest, which means less gold sold each year to cover fees and smaller annual basis adjustments than higher-cost funds produce.12SPDR GoldShares. SPDR Gold MiniShares The 28% rate ceiling itself is the same across every physical gold ETF.
