Best Crypto Tax Software 2025: Koinly vs TokenTax Compared

Stop guessing your crypto taxes. We compare Koinly and TokenTax — the two best crypto tax tools — so you can file correctly and legally.

Crypto tax is one of the most stressful parts of investing in digital assets. Every trade, every swap, every airdrop is a taxable event in the UK. Getting it wrong can lead to penalties — but getting it right is easier than you think with the right software.

I have used both Koinly and TokenTax to prepare my own crypto tax returns. Here is exactly how they compare.

Trying to calculate crypto taxes manually is nearly impossible. A single year of active trading can involve hundreds of transactions across multiple exchanges — each needing to be matched, valued in GBP at the time of the transaction, and reported correctly under HMRC rules (pooling method).

Crypto tax software connects to your exchanges automatically, imports all your transactions, applies the correct tax rules for your country, and generates a report you can hand to your accountant or submit directly.

Koinly is the most popular crypto tax software in the UK. It connects to over 700 exchanges and wallets via API or CSV import, automatically detects DeFi transactions, NFT trades and staking rewards, and generates HMRC-compliant tax reports.
