As crypto investors ring in the new year, a quiet regulatory shift is about to upend one of the sector’s longest-running assumptions: that gains made on-chain are hard for governments to track.
The crypto community acts like taxes are imaginary in large part. This line of thinking will ruin CEX traders; most will unironically end up in jail. Here’s what to know:

Starting January 1, the United Kingdom will implement sweeping new reporting rules that force major crypto exchanges to hand over detailed transaction data to HM Revenue & Customs.
That includes:
- How much investors paid for assets
- What they sold them for
- The profits realized along the way.
- Exchanges must also report users’ tax residency, closing a loophole many relied on to stay below the radar.
The UK is among the first 48 countries adopting the Organization for Economic Co-operation and Development’s Cryptoasset Reporting Framework, or CARF.
By 2027, HMRC will automatically share this data with other participating jurisdictions, including the EU, Brazil, the Cayman Islands, and South Africa. More than 75 countries have committed to the framework, with major crypto hubs like Singapore, Switzerland, and the UAE joining later in the decade.
“This is the beginning of the end for crypto investors who thought they could invest in secrecy,” said Andrew Park, tax investigations partner at Price Bailey.

Why This Matters Beyond the UK
The number of warning letters sent to suspected non-compliant crypto holders jumped to 65,000 in the 2024-25 tax year, more than double the prior year. For the first time, UK self-assessment tax forms now include a dedicated section for crypto gains.
Meanwhile, Federal Reserve Economic Data shows tax authorities worldwide facing widening deficits, sharpening incentives to capture undeclared capital gains wherever they can.
Most of the so-called Western countries are legally taking away your crypto.
Think about it.

Crypto is being folded into the same information-sharing regime that governs bank accounts and securities portfolios. I used to joke that you could lose a hardware wallet in the couch cushions and become financially invisible. Those days are ending fast.
For investors heading into 2026, the risk is no longer just market volatility. It is regulatory certainty and staying on top of your taxes.
