Whether you’re just starting out or managing a complex cryptocurrency portfolio across exchanges, wallets and DeFi protocols, you need a crypto tax position that HMRC will accept. Most generalist accountants treat digital assets like foreign currency and hand you back a spreadsheet. We don’t.
At Myna, we specialise in crypto tax returns and capital gains tax reporting for UK investors, traders and businesses. From transaction history and cost basis tracking to staking rewards, airdrops, NFT sales and liquidity pool income, we calculate it properly, explain it clearly, and file your crypto tax return on time. No jargon, no guesswork. Just HMRC-compliant crypto tax advice, done right. Advice you can trust.
Advice you can trust
Whether you need crypto tax bookkeeping to track your digital asset transactions, help completing your UK crypto tax return, or DeFi tax compliance for complex on-chain activity, our crypto tax team keeps your HMRC filings accurate and on time. From cost basis calculations and wallet reconciliation to capital gains reporting and DeFi yield analysis, we handle the full UK crypto tax position so you don't have to worry about missing deadlines or incorrect figures.
Whether you need help completing your crypto tax return, reporting capital gains on digital asset trades, or ensuring your DeFi and NFT activity meets HMRC requirements, our crypto tax team handles the full picture. From calculating cost basis and pooling across wallets to filing accurate UK crypto tax returns before the January deadline, we make sure your tax position is correct and defensible. HMRC crypto tax compliance isn't a side service for us - it's what we do.
Whether you trade occasionally, farm DeFi yields, or take positions on Polymarket and other crypto prediction markets, our crypto tax return service ensures your income and capital gains are calculated correctly, reported accurately, and filed on time with HMRC
Myna provides complete DeFi tax return services for UK individuals, ensuring every taxable event is calculated accurately and reported to HMRC. Whether you farm yields, provide liquidity, or trade across DeFi protocols, our DeFi tax service ensures your crypto tax return is compliant and defensible.
You don't need to become a crypto tax expert to keep your clients compliant. Myna provides outsourced crypto tax services for accountants, family offices and IFAs who need specialist crypto tax support without building an in-house team. Whether your client trades occasionally, runs DeFi yield strategies, holds prediction market positions, or manages a complex multi-wallet portfolio, we handle the calculations, reporting and HMRC filings - white-label or co-branded, entirely behind the scenes. You retain the client relationship; we deliver the crypto tax expertise.
Every accountancy firm will eventually have a client who needs crypto tax help. Whether it's a trader with a complex exchange history, a DeFi investor with yield farming income, or a client who took large positions on prediction markets and doesn't know how to report the winnings, turning them away means losing the relationship. Myna provides specialist crypto tax outsourcing for accountants, handling the calculations, HMRC reporting and crypto tax return filing so you can keep the client without building an in-house crypto team.
High net worth individuals increasingly hold digital assets across multiple exchanges, wallets, DeFi protocols and prediction markets. For family offices managing these portfolios, HMRC requires accurate crypto tax reporting on every taxable event - from capital gains on trades and staking income to DeFi yields, NFT sales and prediction market winnings. Myna provides specialist crypto tax services for family offices, handling transaction tracking, cost basis calculations, and HMRC-compliant crypto tax return filing.
Your clients are increasingly investing in cryptocurrency, DeFi protocols and prediction markets, and they expect you to guide them on tax. When you don't have specialist crypto tax expertise in-house, referring them elsewhere risks losing the relationship entirely. Myna provides white-label crypto tax support for IFAs, handling your clients' crypto tax calculations, HMRC capital gains reporting and crypto tax return filing under your brand.
Success Stories
“I had an initial 15 minute call with one of the best, if not the best, crypto accountants out there. He walked me through the expectations and implications and this short conversation was very reassuring. At first glance, their services might seem a bit pricey, but that’s because they truly know what they’re doing. I’m looking forward to speaking with them in April to sort out my portfolio taxes.”

I’ve used Myna now for several years and they have dealt with my tax affairs in a friendly and efficient way. I have had to have minimal involvement in the process other than having to supply documentation. My tax affairs are not straight forward but these guys always do an amazing job. I would not hesitate in the slightest to recommend Myna for all your tax requirements.”

“I was looking for an accountant to help me with my crypto assets, the more I researched this, I realised quite quickly that it was quite a complex area for a standard accountant and that I would require somebody with specialist knowledge. I came across Myna after looking at a few of their videos on YouTube and seeing Joe being interviewed about Crypto taxes and realised that he was very knowledgeable and also is involved with crypto himself. I have found everyone at Myna to be very helpful with my queries and concerns and found them to be very professional and knowledgeable about this new asset class. They completed my self-assessment form without any fuss or complications, I will definitely be using Myna again next year and would highly recommend them if you need a tax specialist to assist you with your crypto taxes.”
