Bear with me...

Last year, many UK dog breeders received enquiries from HMRC regarding income from breeding and puppy sales.

For years, some assumed that occasional dog breeding activity was simply too niche, too small, or too difficult for HMRC to identify.

Then the letters started arriving. Suddenly it became clear that HMRC knew far more about the activity taking place than many people had expected.

The Kennel Club actively signposts tax obligations to its members.

Crypto is heading down a remarkably similar path, with more intent and more clear reporting paths from the equivalent of kennels to The Revenue.

In the same year, there were 66,000 nudge letters to suspected crypto owners, despite many investors operating under the assumption that crypto was somehow different:

  • Too complex for tax authorities to understand
  • Too difficult to trace
  • Too fragmented across wallets and exchanges
  • Too much data for anyone to analyse effectively

That assumption is becoming increasingly difficult to maintain. Arguably it’s collapsing fast.

HMRC's recent research with crypto investors and industry participants provides a fascinating insight into how the department is thinking about the market, investor behaviour, and compliance challenges.🔗 https://www.gov.uk/government/publications/research-with-cryptoasset-investors-and-industry-participants/qualitative-research-with-cryptoasset-investors-and-industry-participants-enhancing-hmrcs-insight-into-to-the-cryptoassets-industry-and-investors-i

At the same time, the Crypto Asset Reporting Framework (CARF) is moving from policy discussion to operational reality.

For the first time, tax authorities around the world will receive standardised reporting from cryptoasset service providers, creating a level of transparency that simply hasn't existed before.

The lesson?

If your tax strategy relies on HMRC not knowing you own crypto, that is a bit like assuming nobody will notice you've suddenly got 47 dalmatian puppies running around the garden.

The age of "HMRC probably won't see it" is rapidly giving way to the age of "HMRC already has the data."

Whether you're a crypto investor, accountant, exchange, or tax adviser, now is probably a good time to make sure your records are in order.

Because eventually, everybody gets asked about the puppies. 🐾

    Does SwissBorg report to HMRC? (2025/26 UK guide)

    Indirectly, yes. SwissBorg is a Swiss-founded wealth app whose European arm is now authorised as a Crypto-Asset Service Provider (CASP) under MiCA, so it is not an offshore venue, and from 2026 the kind of provider it operates may fall within the Cryptoasset Reporting Framework that feeds customer data to HMRC. SwissBorg is also different from the exchanges people usually ask about: it is built around yield. The payouts from SwissBorg Earn are generally income, taxed when you receive them, and every in-app swap is a disposal for capital gains tax, even though the app feels like a savings account. Here is what HMRC can see, where SwissBorg sits with regulators, why its yield features are so easy to misreport, and what to do if you are behind.

    Does Revolut report to HMRC? (2025/26 UK guide)

    Revolut's UK crypto services are provided by Revolut Ltd, a UK-incorporated firm on the FCA's cryptoasset register. Under the UK's Cryptoasset Reporting Framework, that makes it a UK reporting cryptoasset service provider: it must collect customer and transaction data and report it to HMRC annually. This guide explains what is reported, when HMRC receives it, and what to do if you have gains or income you have not declared.

    Does Poloniex report to HMRC? (2025/26 UK guide)

    There is no public evidence that Poloniex currently sends HMRC a routine direct feed. However, it is not beyond HMRC's reach: activity may be visible through UK banks and other exchanges, existing information-exchange channels and, where the relevant provider is in scope, the Cryptoasset Reporting Framework. Poloniex is also on the FCA warning list, and older accounts can contain spot trades, historic lending returns, staking rewards and margin activity that are easy to misreport. Here is what HMRC can realistically see, how those transactions may be taxed and what to do if you are behind.
