Crypto cards and tax: what happens when you spend crypto

Why spending crypto can be taxable

Most tax authorities treat crypto as property, not money. So when your card turns your crypto into dollars to pay a merchant, you’ve technically sold it. If it’s worth more than you paid for it, that’s a capital gain. If it’s worth less, it’s a capital loss.

In most places that $10 is taxable, even though all you did was pay for dinner.

Why stablecoins make this much easier

You still technically sell a stablecoin when you spend it, but the gain is usually so small that the paperwork stays simple. How crypto cards work covers loading a card with stablecoins.

What about the cashback?

It depends where you live, and the rules aren’t as clear as they should be.

In the US, the IRS has long treated card rewards earned on spending as a rebate on what you bought, not as income. There’s no IRS guidance written for crypto cashback yet, but most tax professionals apply the same logic. Sign-up bonuses that don’t depend on spending are different, and are more likely to count as income.

In Australia it’s less settled. We couldn’t find ATO guidance written for crypto card cashback, and several crypto tax providers treat it as ordinary income, at its value on the day you receive it.

In the UK, HMRC’s general guidance treats cashback as a discount rather than taxable income, as long as you’re not trading. Most UK crypto tax specialists expect the same for cashback paid in crypto.

Wherever you are, selling or spending the cashback itself later is a disposal, with its own gain or loss.

In the United States

Crypto is property, so spending it is a sale. Hold it for a year or less and any gain is short-term, taxed like ordinary income. Hold it for more than a year and it’s long-term, usually at a lower rate. Every sale goes on Form 8949, whatever the amount.

There’s no small-purchase exemption yet. A $300-per-purchase exemption has been proposed in Congress, with White House support, but as of October 2026 it hasn’t passed.

In Australia

Spending crypto is a CGT event, the same as selling it. If you held it for more than 12 months, you can usually halve the gain with the 50% CGT discount.

There is a personal use asset exemption for crypto bought for less than $10,000, but the ATO reads it narrowly. It’s meant for crypto you buy and spend fairly quickly on things for yourself. If you held it as an investment first, it usually won’t apply, and losses on personal use assets can’t be claimed. Our Australia page compares the cards open to Australians.

In the United Kingdom

Spending crypto is a disposal for Capital Gains Tax. The first £3,000 of gains each year, across everything you own, is tax-free. Above that, gains are taxed at 18% or 24%, depending on your income.

From January 2026, UK crypto platforms collect your details and report your activity to HMRC each year, so it pays to keep your own records in order. Our UK page compares the cards open in the UK.
