Taxxy vs Koinly
An honest comparison for EU crypto traders — especially in Spain and Italy where official PDF forms matter most.
Our verdict
Koinly has far more exchange integrations — it is a mature, well-established platform. Taxxy has closed most of the blockchain gap (191 chains vs Koinly's verified 170+, close enough that neither side can claim a clear win on an open-ended "+" figure) and wins on price accuracy (exchange OHLCV vs aggregator pricing), EU-specific official PDF forms (including the Modelo 721 introduced in 2023 and Italy's official Modello Redditi PF2 template), and cost basis method breadth. If you are a Spanish or Italian trader who needs accurate EUR-denominated valuations and a ready-to-file government PDF, Taxxy is the stronger choice. If you need ~800–900 exchange venues, Koinly covers more ground.
Where Taxxy wins
- Exchange-specific OHLCV pricing (minute-level accuracy, 20–50× more precise than Koinly's aggregator)
- More cost basis methods: 6 (FIFO, LIFO, HIFO, ACB, Share Pooling, SpecID) vs Koinly's 5
- Official EU government PDFs: Modelo 100 & 721 (Spain), Quadro RT/RW with official PF2 Modello 2025 template (Italy)
- AI-powered CSV fallback for unknown exchange formats — unique in the industry
Where Koinly wins
- Far more exchange integrations: ~800–900 venues vs Taxxy's 114
- More established product with larger user base and support team

FAQ
Common questions
Can I switch from Koinly to Taxxy?
Yes. Taxxy can import your transactions directly from your exchange APIs or via CSV export. If you have a Koinly transaction CSV export, Taxxy's smart CSV parser will recognise the Koinly format automatically.
Does Taxxy support the same countries as Koinly?
Taxxy has 62 country calculators and 18 official PDF form fillers, with a strong focus on EU jurisdictions. Koinly supports 100+ countries (~20+ with localized forms). If your country is not Spain, Italy, France, Germany, Poland, UK, US, or another major EU market, check our country list first.
Why does price accuracy matter for Spanish and Italian traders?
AEAT (Spain) and Agenzia delle Entrate (Italy) require gains reported in EUR at the time of each transaction. Aggregator pricing can be off by 2–5%. Taxxy uses the actual exchange OHLCV data from the exchange where the trade occurred — typically accurate to within 0.1%. This difference can meaningfully affect reported gains on large portfolios.
Does Koinly support Modelo 721?
Koinly's Spain support has improved, but Modelo 721 (the 2023 foreign crypto declaration replacing Modelo 720 for crypto) is a relatively new requirement. Taxxy was built with Modelo 721 in its core reporting flow from the start.
