Signup Bonus
Free plan — 10,000 tx + gains preview
The free tier imports transactions and previews capital gains but does not include downloadable tax reports — a paid plan for the relevant tax year ($49 Newbie / $99 Hodler / $179 Trader / $279 Pro) unlocks the report pack.
Expert Verdict
Koinly generates tax reports for 20+ countries, including the IRS pack (Form 8949, Schedule D, Schedule 1) and the HMRC Capital Gains Summary with full Section 104 share pooling. The free tier imports up to 10,000 transactions and previews your capital gains; you pay per tax year ($49–$279 depending on transaction count) only when you need the downloadable report. Its standout strength is DeFi: roughly 1,000 direct integrations plus support for 7,200+ DeFi protocols, with automatic categorisation of staking, lending, LP and NFT activity. US users get a per-wallet cost-basis migration tool for the IRS rules that took effect in 2025.
