The UK is tightening its grip on cryptocurrency transactions, requiring full traceability by 2026. This move aligns with global trends as countries like Spain and Switzerland also update their crypto tax rules. Meanwhile, the UK introduces DeFi-friendly tax policies, delaying capital gains taxes until tokens are sold. Here’s a deep dive into the changes and their implications.

Why Is the UK Forcing Crypto Platforms to Track All Transactions?

Starting in 2026, the UK will require crypto platforms to report every transaction—local or international—to tax authorities. This expansion of the Cryptoasset Reporting Framework (CARF) grants HM Revenue & Customs (HMRC) immediate access to user data. Previously, only cross-border transactions were tracked, but domestic ones will now be included to bolster tax compliance ahead of a global data-sharing initiative in 2027. Think of it as the crypto equivalent of your bank sending annual statements to the IRS.

How Does the New DeFi Tax Rule Benefit Users?

In a win for DeFi enthusiasts, the UK will only tax capital gains when tokens are sold, not during internal protocol transactions. This "no premature taxation" approach mirrors how DeFi actually works—no more phantom taxes on staking rewards or liquidity pool moves. The BTCC team notes this could spur more DeFi adoption, as users won’t face tax headaches for simply participating in protocols.

Global Crypto Tax Trends: Who’s Doing What?

The UK isn’t alone. Spain proposes hiking crypto taxes to 47% for individuals, while Switzerland delays its crypto data-sharing rollout to 2027. Meanwhile, the U.S. might let you pay federal taxes in bitcoin (thanks to the "Bitcoin for America Act"). It’s a regulatory patchwork, but one thing’s clear: governments want their cut of the crypto pie.

What’s Next for Crypto Regulation?

With CARF becoming law in 2026, UK platforms must prep for rigorous reporting. Expect more countries to follow suit—after all, nobody wants to be the tax haven that misses out on billions in crypto revenue. As for investors? Keep records cleaner than a Swiss bank vault.
