Paying capital gains on a cup of coffee: how crypto taxes reach everyday purchases

Buy a four dollar coffee with bitcoin and, in the eyes of the IRS, you did two things at once. You bought a drink, and you sold property. The selling part is what catches people off guard. If the coin you handed over was worth more than you paid for it, that purchase produced a capital gain, and that gain is taxable.

This is a big part of why crypto never settled into everyday spending the way its early backers hoped. A form of money you have to report to the IRS every time you use it is a hard sell against a debit card. The rule traces back to the first IRS guidance on digital assets in 2014, and it still applies in 2026.

How the IRS treats crypto

The IRS does not treat bitcoin, ether, or other tokens as currency. It treats them as property, the same category as a share of stock, a rental house, or a painting. Sell property for more than you paid and you have a capital gain. Sell for less and you have a capital loss.

Two numbers set the tax on any disposal. The first is your cost basis, which is what you paid for the coin including fees. The second is the fair market value in dollars at the moment you spend or sell it. The gap between them is the gain or loss you report.

How long you held the coin decides the rate. One year or less and the gain is short term, taxed at your ordinary income rate. More than a year and it is long term, taxed at the lower long-term capital gains rates, which for 2026 are 0, 15, or 20 percent depending on your taxable income.

Why the coffee counts as a sale

Spending crypto is a disposal, and a disposal is a taxable event. It makes no difference that you walked away with a latte instead of cash. The IRS looks at what the coin was worth when you spent it and compares that to your basis.

Here is the math. Say you bought 0.01 BTC a few years ago for 40 dollars, and today that fraction is worth 55 dollars when you spend it on coffee and a pastry. You have a 15 dollar long-term capital gain to report, even though no money moved through your bank account. Repeat that across dozens of small purchases in a year and you have dozens of tiny gains and losses to track.

That record-keeping, more than the tax itself, is what keeps crypto out of the checkout line. Few people want to run a basis calculation to buy lunch.

The small-purchase exemption that keeps not happening

Lawmakers have noticed the problem. Versions of a bill often called the Virtual Currency Tax Fairness Act have been introduced in Congress more than once, each proposing a de minimis exemption that would let you ignore gains on small personal purchases below a set threshold, commonly 200 dollars. As of 2026, no such exemption has become law. Every personal-use disposal, however small, is still reportable.

Even if that changes, it would cover only modest everyday spending. Selling a sizable position or converting crypto back to dollars would stay fully taxable.

What the IRS already sees

Reporting is no longer on the honor system. Starting with the 2025 tax year, digital asset brokers file Form 1099-DA reporting the gross proceeds from your sales, with cost-basis reporting phasing in for later years. Exchanges send that form to you and to the IRS, so the agency can match it against what you report.

Every Form 1040 also asks, near the top, whether you received, sold, exchanged, or otherwise disposed of a digital asset during the year. Spending crypto on a purchase is a yes. Answering honestly and reporting the gains costs far less than a matching notice does later.

What to keep track of

If you spend crypto at all, keep enough detail to compute each gain:

• The date you acquired each coin or fraction and what you paid, including fees. That is your basis and the start of your holding period.
• The date of each purchase or sale and the coin's dollar value at that exact moment.
• Which specific units you spent, if you hold coins bought at different prices. The lot you pick changes the gain.

Portfolio and tax software can pull most of this from exchange history, but the output is only as good as the records behind it. Self-custody wallets, on-chain transfers, and coins moved between platforms are where basis usually goes missing.

When to bring in a pro

A handful of trades is something most people can handle with software. The work gets harder once you have multiple exchanges, self-custody wallets, staking or mining income, DeFi activity, or years where you spent crypto and kept no basis records. That is the point where a specialist tends to save more than the fee, in tax owed and in mistakes avoided.
