Stablecoin Taxes: What the IRS and HMRC Actually Say

What this page covers, and what it is not

This page covers the United States and the United Kingdom only. The US guidance is current as of 11 September 2026. The UK guidance the same date. Both were read from the authorities’ own pages. This is educational information. It is not tax advice. It considers no one’s individual circumstances. The block above states the full terms.

The United States: property, then one stablecoin answer

The foundation is old and general. Notice 2014-21 treats virtual currency as property ^[3]. It states virtual currency is not currency for foreign-currency gain and loss purposes ^[3]. The IRS hub page restates the framing. Digital assets are property, not currency, for US federal tax purposes ^[1]. Income from digital assets is taxable ^[1].

Stablecoins sit inside that rule by name. The IRS definition lists stablecoins among its examples ^[1].

Treasury and the IRS later considered excluding stablecoins from the broker regulations. They declined. T.D. 10000 states stablecoins unambiguously fall within the statutory definition of digital assets ^[5].

The rule survived its own review.

The recognition rules follow the property framing. Selling is a disposition. Exchanging for another digital asset is a disposition. Spending is a disposition ^[1]. Each carries a capital gain or loss if the tokens were held as a capital asset ^[1].

Two negatives complete the set. Buying with dollars alone is not a Yes event on the return’s digital-asset question ^[1]. Moving tokens between one’s own wallets is not a disposal ^[1].

One answer is stablecoin-specific, and recent. Q100/A100 was added to the IRS FAQ on 15 December 2025 ^[2]. The scenario: a holder exchanges stablecoins. No broker report is filed. The answer: if the stablecoins were held as capital assets, gain or loss is recognized even when the broker reports nothing ^[2]. The taxpayer must still report it ^[2].

Broker reporting has its own stablecoin rule. One caution travels with it. Under T.D. 10000, brokers may use an optional aggregate method for qualifying stablecoins ^[5]. No return is required when designated sale proceeds stay at or under $10,000 for the year ^[5]. That figure is a reporting threshold. It is not a tax exemption. Not a de minimis tax break. The recognition rule above applies regardless.

Staking has explicit law. Revenue Ruling 2023-14 holds that proof-of-stake rewards enter gross income at fair market value ^[4]. The timing is specific: the year the taxpayer gains dominion and control ^[4].

Then the silence, stated as a silence. No IRS digital-asset guidance addresses interest from stablecoin-lending products. The full FAQ sets were read on 11 September 2026. They contain no lending-interest question. The nearest authorities cover staking rewards and payment for services ^[4]. Neither is lending interest. This page does not extrapolate an answer the authority has not given.

The United Kingdom: disposals, pools, and one draft change

HMRC’s manual gives stablecoins their own subsection in its token taxonomy ^[6]. Then it sets the operative rule. Treatment depends on the nature and use of the token. Not on its definition ^[6]. HMRC does not consider cryptoassets to be currency or money ^[6]. The foreign-currency tax provisions therefore do not apply.

Under current law, most individuals hold as a personal investment. Capital Gains Tax applies on disposal. A disposal includes several acts. Selling for money. Exchanging for a different token type. Paying for goods or services. Giving tokens away, other than to a spouse ^[7]. Each token type sits in its own Section 104 pool ^[8]. A same-day rule and a 30-day rule govern matching before the pool ^[8]. The consumer guidance carries the current numbers. An allowance of 3,000 pounds a year through the 2026 to 2027 tax year. Individual rates of 18 and 24 percent ^[11].

Non-trade staking awards are taxed as miscellaneous income ^[9]. The measure is the pound-sterling value on receipt ^[9]. Lending and DeFi returns are measured at money’s worth. Their nature, income or capital, follows the facts ^[10]. An agreed rate indicates a revenue receipt. The manual says such a receipt has a similar nature to interest, while not being interest for tax purposes ^[10].

Here too, a silence is banked. The manual’s capital gains chapters contain no stablecoin-specific relief under current law. That is a negative finding from reading the chapter set, dated 11 September 2026 ^[7]. It is not a prediction.

The UK change drafted for 2027

The current-law paragraphs are one of two rules UK readers need. The second is drafted, announced, and not yet law. On 13 July 2026 the government announced the Tax treatment of stablecoins measure ^[12]. Draft legislation sits with Finance Bill 2026-27 ^[14]. It followed a Call for Evidence that ran 26 March to 7 May 2026 ^[12].

As drafted, it takes effect 6 April 2027 for individuals and trustees. 1 April 2027 for companies ^[13]. Disposals of eligible stablecoins would be exempt from Capital Gains Tax, under a new section 269A ^[14]. A transitional deemed disposal precedes the start date ^[13]. Qualifying stablecoin returns would be treated as interest, taxed as savings income, under a new section 380B ^[14]. The policy document’s own summary: the measure will treat eligible stablecoins more like money for tax purposes ^[13]. Draft law is not law. Until enactment, the current-law rules govern. Any UK 2027 claim a reader encounters deserves that qualifier ^[12].

The records both regimes expect

Both authorities put the record-keeping burden on the taxpayer. Both say so in their own words. The IRS requires records of purchase, receipt, sale, exchange, or other disposition ^[1]. It requires the dollar fair market value of anything received as income ^[1]. HMRC’s manual lists what the individual must keep. Token type. Dates. Amounts. Units. Pound-sterling values at transaction dates. Wallet addresses ^[11]. The manual cautions that exchanges may not retain records ^[11]. Reading a tax page is not keeping tax records. The records are the reader’s own obligation under both regimes.

Where this page sits

The regulation hub holds the other regimes. The GENIUS Act page covers the US regulatory framework beside this tax picture. The UK page holds the British regulatory rules. The tokens are introduced at stablecoins and the stablecoin intro.
