Understanding the Tax Implications of Holding IAUM (iShares Gold Trust Micro) in the United States

Summary: If you’re holding IAUM (iShares Gold Trust Micro) or thinking about investing in it, there are several U.S. tax implications you’ll want to have on your radar. In this article, I break down how IAUM is taxed, what happens when you sell, the paperwork headaches (yes, there are a few), and why you need to pay attention come tax time. I also add in some personal missteps from filing season, plus quotes from pros at PwC and the IRS. If you’re juggling different asset types or planning to take profits, save yourself a headache and read on.

What Problem Does This Solve?

Many people buy IAUM because it’s a simple way to access gold without hoarding coins or paying vault fees. But unlike regular stocks or mutual funds, IAUM is structured as a grantor trust and tracks physical gold. This makes its tax treatment very different—and not in a good way for long-term holders who forget the rules. Believe me, nothing’s less fun than discovering a surprise tax bill for your gold ETF gains, just because you didn’t know the difference between “collectibles” and “capital gains.” This article exists to clear up those traps and actually show, with screenshots and real stories, how to handle IAUM at tax time.

How IAUM Works—And Why Its Taxes Are Weird

Let’s start with the basics. IAUM is an Exchange Traded Fund (ETF), but NOT like SPY or QQQ. It represents fractional shares in physical gold bars held in a vault. That “physical asset” link makes all the difference at tax time, because the IRS considers IAUM (and similar gold ETFs like GLD, IAU, SGOL) to be an investment in precious metals, not just regular securities.

• IAUM is a grantor trust, not a corporation—meaning, for tax purposes you own gold, not just shares in a company.
• The IRS says gains from sales of physical gold are taxed as collectibles (IRC Section 408(m)).
• The maximum federal tax rate on collectibles is 28% (see IRS Topic No. 409), which is higher than the regular long-term capital gains rate (15-20%).

So, even if you buy IAUM and never touch a gold bar, Uncle Sam treats you just like a coin collector. When I first started out, I assumed all ETFs had the same rules—wrong. My CPA caught the mistake, but only after I’d filed.

Buying IAUM Is Simple—But Selling? That’s Where the Tax Story Begins

Step-by-Step: What Happens When You Sell IAUM

1. You buy IAUM using your brokerage account, just like any other stock or ETF.
2. Your shares increase in value—congratulations, gold prices are up!
3. One day you decide to sell. Here’s where things get interesting. When you sell shares, you trigger a taxable event.
4. Your brokerage sends you a 1099-B at year-end. This form will show the proceeds and your cost basis.
5. On your tax return:
   • If you held IAUM for more than one year, your gain is taxed at the collectibles rate (up to 28%).
   • If you held for one year or less, it’s taxed as short-term capital gains, which uses your ordinary income rate (could be as high as 37%).

Personal note: The first time I did this, TurboTax flagged my IAUM sale as a regular capital gain. Had to override it and click through IRS instructions to get it coded as a collectible gain. Missed this the first year—had to amend past returns (lesson learned!).

Practical Example (With TaxCalc Screenshot)

Suppose you buy 100 shares of IAUM at $20 each (total $2,000). After 18 months, you sell all shares at $30 each ($3,000). Your gain is $1,000.

• The $1,000 gain is taxed at 28% (collectibles rate) if you’re in the top bracket, so you owe $280 in federal taxes just for this sale.
• 
• That 28% rate applies even if your regular capital gains rate is only 15%!

How to Report: It’s Trickier than Stocks, but Doable

• Brokers rarely check the “collectibles” box for you—you have to label it right in your tax software.
  Screenshot:
• Make sure to disclose if “Section 1256 Contracts” or “Section 1256 gain/loss” don’t apply to you (those are for regular ETFs/futures, not grantor-trust precious metals like IAUM).
• If you’re unsure, IRS Publication 544 (linked here) has a whole section on collectible gains.

What Else To Watch Out For: State Taxes, Wash Sales, and RMDs

• If you hold IAUM in a tax-advantaged account (like an IRA), you don’t pay tax until withdrawal. But minimum distribution rules still apply.
• State tax rules vary—some high-tax states will also tax your gold ETF gains as ordinary income.
• Wash sale rules do not apply to collectibles, but cost basis tracking is still your job.

Case Study: My IAUM Sale That Went... Sideways

In 2022, I sold $7,500 of IAUM after holding for nearly two years. Figured my gain would count as long-term capital gains. Uploaded my Charles Schwab 1099-B to FreeTaxUSA, and it just auto-filled as a security sale. Only after digging into IRS Topic 409 did I realize I needed to recode this as a “collectible” gain. Had to manually override the category—took me four tries and three coffees to figure out the right dropdown. The IRS instructions are not user-friendly. If you don’t catch this, you can end up with a notice or an underpayment. Here’s a forum thread that describes exactly what I encountered: Bogleheads—Gold ETF Taxation Discussion.

Summary: Things to Remember Before Selling IAUM

• Know your rates: IAUM is taxed as a collectible (up to 28% federal rate). Don’t bank on regular capital gains rates.
• Check your brokerage forms (1099-B): These may not auto-mark sales as collectibles. Double-check with your CPA or tax software.
• Reporting is your job: Brokerages often report IAUM like regular ETFs, but the IRS wants collectible reporting. Read IRS Topic 409 to be sure.
• State taxes can differ: Remember to check state guidelines, especially in high-tax states like California or New York.
• Use the right accounts if possible: Holding IAUM in a Roth IRA or 401(k) can avoid immediate taxation (though special rules apply for gold in IRAs).

Next Steps If You Hold or Plan to Sell IAUM

1. Before selling, review IRS Topic 409 and your brokerage’s FAQ pages.
2. Double-check how your transaction is coded in tax software—if possible, select a “collectible gain” reporting option.
3. If you’re not sure, ask a CPA or tax specialist who’s familiar with ETF/precious metals reporting. This is especially important if you mix various asset classes.
4. For large accounts, keep all 1099-Bs and trade confirmations (I keep mine in a Google Drive folder because I once lost paper copies and had to request them all over again—another pain).

Bottom line: IAUM brings gold exposure, but with a twist at tax time. A little prep (and reading IRS Topic 409!) goes a long way to avoid overpaying—or paying the IRS twice. If you’re picky about numbers or planning to cash out during a good market run, don’t get tripped up by old ETF habits.
Pro tip: Even if you make a mistake, remember: the IRS lets you amend past returns. Trust me, you won’t be the first to mislabel a gold ETF!
