A $100,000 Gold Gain in IAU Hands the IRS $28,000. The Same Gain in VOO Costs $15,000

Ride gold up for a decade, cash in a $100,000 profit, and the IRS can take 28% off the top. Sell the same $100,000 gain in an S&P 500 fund, and the federal bite drops to 15% for most long-term holders. That is a roughly $13,000 gap on identical dollar profits, and it is baked into how iShares Gold Trust (NYSEARCA:IAU) is legally structured.

Collectibles Tax Trap Hiding in a Gold ETF

IAU is a grantor trust holding physical gold bullion. The IRS treats a sale of your shares as a sale of the underlying metal, which falls under Section 408(m) collectibles rules. Long-term gains are taxed at your ordinary rate, capped at 28%. Short-term gains are taxed as ordinary income, just like a stock.

Now let’s put a dollar figure on it. Gold started the year incredibly strong. IAU is up 24.63% over the past year, 139.49% over five years, and 220.48% over the past decade, with spot gold trading near $4,429 per ounce. Investors sitting on real gains are staring at a real tax bill. A $100,000 long-term profit in IAU at the top 28% collectibles rate hands the IRS $28,000. The same $100,000 gain in Vanguard S&P 500 ETF (NYSEARCA:VOO) at the 15% long-term capital gains rate costs $15,000. Same gain. Different wrapper. About $13,000 more owed to Washington.

Fee Drag Nobody Puts on the Fact Sheet

The tax hit is the headline cost. The expense ratio is the quiet one. IAU charges 0.25% annually, which works out to roughly $25 per year per $10,000 invested. VOO charges 0.03%, or roughly $3 per year per $10,000. On a $100,000 position held ten years, that is the difference between paying about $250 a year for gold storage and paying about $30 a year to own 500 large-cap U.S. companies.

Gold also produces no dividends and no interest. Every basis point of expense comes straight out of price appreciation. An S&P 500 fund at least kicks off a dividend yield to offset its (tiny) fee. IAU shareholders pay 100% bullion exposure plus a storage and sponsor fee, with nothing coming back the other way. Over a full market cycle, that structural drag compounds against you before the collectibles tax even shows up on your return.

Cheaper Gold Wrappers Sit Right Next to It

If you want the gold exposure, the tax treatment is identical across every physical-bullion trust. That is the point worth internalizing. Switching from IAU to SPDR Gold MiniShares (NYSEARCA:GLDM) leaves the 28% collectibles issue intact, because GLDM is also a grantor trust holding physical gold. What it changes is the fee gap. GLDM’s expense ratio runs at roughly 0.10%, versus IAU at 0.25%. Peers like abrdn Physical Gold Shares ETF (NYSEARCA:SGOL) and GraniteShares Gold Trust (NYSEARCA:BAR) run around 0.17%. Same metal in the vault. Same tax code. Lower annual toll.

What This Means for You

Gold has done its job for holders over the past decade, but the after-tax math is not the same as the price chart. Before adding more IAU, or trimming what you already own, the useful question is simple. Do you know your after-tax return, priced at the collectibles rate, and does the cheaper physical-gold wrapper next door give you the same exposure for less annual friction? The 28% collectibles rule is one of several IRS quirks that quietly drain retirement accounts (we mapped it and eight others in a free guide here: The Retiree’s Tax Trap Map). The fund’s marketing just does not lead with it.
