Crypto Trading, Staking Pools and Tax
Essential Time Sensitive information

The contents of this page do not constitute Tax advice

... but I strongly urge you to look deeper into your own activities and enable yourself for what is coming - Be prepared, as things have changed with the Tax authorities around the world in the Cryptocurrency sector and will affect millions of Crypto Traders, regardless of activity or value, large and small. 

Therefore, I highly recommend that you take some time to read this page, if you have participated in any type of Crypto Investments, including Trading, Staking, Swapping, Liquidity pool activities, Transferring, particularly over the last 2 to 3 years, and pretty much regardless of the value, even if you think it is too low to matter.

A quick example - The Token Swap catch

This content of this article applies, even if the only Crypto activity that you have engaged in is just to swap one type of Crypto Coin / Token for a different token.

In this extremely common scenario, many crypto investors think that when you do a crypto token swap, that just because no fiat / real money hits your bank account as a result of this action, therefore no tax is payable. Well in the UK at least, think again, as things are not what you think...

Many Crypto traders may do this swapping activity hundreds of times during a year, especially when engaged in the various decentralized staking platforms such as Origin, Spartan, Awake, Olympus Dao, Uniswap, Lido, Jito, Rocket pool, and many, many more like these. The combined value that results from token swaps on these types of platforms can add up to a substantial tax liability, or at least a reportable one, over months or years, depending on your jurisdiction, that many people may currently be blissfully unaware of.

Please read on - do not get caught out.

What Lies Ahead - CARF

Many traders will of course already be aware of CARF, but thousands of new traders are joining Crypto platforms daily and trading, holding, swapping or staking coins for the first time. So, on that basis, I need to share what is coming, and is in fact already in progress behind the scenes in many countries.

This is not written to worry or scare, but to empower and help you, from one fellow average Crypto trader to another. 

CARF and the Countries involved

My awareness of this started, having recently, having been doing some tax related calculations for my submission deadline in the UK of January 31st 2026. In 2025.

I started activities on various platforms with Defi Staking, initially to get a feel for this. I had engaged with some Smart contract "investments" a few years ago, but these never really came to anything. But as the Crypto Investment level that I commenced last year was a bit higher, albeit not huge, I decided to dig deeper to see what my Capital gains and Income Tax liabilities are/were.

With this in mind, I started searching around for facts, tools, apps etc to help me along with this process and I came across something called CARF.

I suspect that some people may not have seen this, some may have seen it, and some may possibly not fully realised its implications. This is not meant to offend anyone, but rather the opposite, to ensure that everyone now fully understands its meaning.

CARF stands for the Crypto Asset Reporting Framework. That says it all really.

44 countries have already signed up to it and dozens more will follow. It basically means that all Crypto-Asset Service Providers, such as crypto exchanges, brokers, and digital asset dealers, must register and collect their users tax data and send it to the Tax authority within their jurisdiction.

CARF is run by the OECD, which stands for the Organisation for Economic Co-operation and Development. OECD member countries, or Jurisdictions, will collect and report the user names, transaction values and other details carried out across all Crypto-to-Fiat exchanges, Crypto-to-crypto trades, and Crypto retail payment transactions.

I have myself noticed this data collection activity in action since January this year on a few occasions, when I started sending funds from my Coinbase account to my private Metamask and Token pocket wallets.

Each time during a send to one of my wallets, a pop up appeared asking me to confirm that I was sending to my own self custody wallet, plus the token sent and the value. If no tick was placed in the box, then no transaction could be made.

I am advised that this is the basic reporting data that is now sent to the HMRC in the UK, and it is quite likely the same thing will happen for the Tax Authority in the country that you live in.

But note, I am not a Tax advisor and the above supposition is just gathered from my own research.

So how does your Tax Authority use the CARF data?

Simply put, the data gives the authority a summary of your crypto activities, including your name, times, dates, tokens, values and self custody wallet addresses. From there on, everything is on the blockchain(s) and all ongoing transactions of any type or category are wholly visible. (including of course, those countless swaps of one type of Crypto Coin / Token for a different token.)

So now it gets serious. Armed with this up front, fairly basic, yet powerful data, your Tax authority now has a very good picture of your Crypto trading activities and it certainly gives them sufficient information that they can use to approximate at least part of your Crypto income and gains. (It may not be aware of any self custodial wallets that were not funded via your exchange.)

When you come to file your tax return, at whatever the time of year you have to do this, on receipt of this, they can then start to analyse things.

I cannot say to what degree this will happen, as nobody can know this, but given the ever increasing development in AI tools and technology, analysing peoples data and activities at great scale and accuracy is already being done in the marketing sector and can only be something that we must consider as a real possibility and even a very high likelihood by the Tax authorities

Therefore the importance of an accurate tax filing is now even more important than ever before, as we have to assume that the Tax authority already have a good upfront idea of what to expect from you.

Letters are already being sent 

The UK HMRC are now engaged in an active campaign of sending out what are referred to as "nudge" letters.

According to available public information data, there were 81,172 crypto-related nudge letters sent out during the 2025/26 tax year. This amount had more than doubled on the previous year, and this increase could reflect a similar trend during the next tax year ahead.

These letters are not a tax demand, but also should not be dismissed or treated like a mailshot. In the UK, The nudge letter is not an accusation and it does not mean that HMRC has already calculated a tax bill.

But, the nudge letter does tell you the most important thing - That the information available to the HMRC does not sit comfortably with what you have already declared. It may just give you a limited window to work out whether or not anything needs to be corrected.

So is all this activity worth their while? 

I can only say this, once again using facts available from publicly accessible information:

HMRC has already recovered about £8.3 million from just 502 crypto disclosure settlements within its jurisdiction, across the 2024/25 and 2025/26 tax years. This is before it has even commenced in earnest with the data related to CARF, of which they will recieve the first detailed report form the various Crypto exchanges in May 2027

Based on the above single fact, regardless of where in the world you live, please make your own assumptions about the CARF initiative and act accordingly.

Also remember this. Please do not think it does not affect you because of where you may reside in the world. This initiative has a global reach, with 77 countries signed up to this so far, and sooner or later it will affect you - The OECD has established a framework to automatically share cryptocurrency transaction and taxpayer information between all participating countries for tax transparency

What can I be doing for peace of mind?

The first thing that I did was not to get a good accountant, although I do have one now, and such a person is extremely valuable at some point in your investment trading journey. Any investment in this area will be repaid many times, especially as and when you continue to grow.

I decided to stop the worry, avoid the letters, avoid the investigations and avoid the fines. The first single thing that I did for peace of mind, that really did change everything for me was to get some dedicated, highly effective, proven, simple to use, yet commonly available online software that could 95% automate the work required for me to get an accurate picture of my Crypto Tax liabilities.
