CryptoTax now supports Base. Add your wallet and we automatically calculate your taxable gains according to Belgian FIFO rules.
Base is fully supported by Cryptotax.
Simply add your Base wallet on Cryptotax and we do the rest: automatic transaction detection, FIFO calculation, and a complete Belgian tax report that your accountant understands.
Why Base matters
DeFi is growing fast, but especially on Layer 2.
Base, developed by Coinbase, offers lightning-fast transactions at a fraction of Ethereum's cost. More and more Belgian users are moving their DeFi activities to this network.
That is good news for your gas fees, but also a new challenge for your tax return.
Because how do you keep track when your assets are spread across multiple networks?
That is where Cryptotax steps in.
As simple as Ethereum
Our Base support is built on the same reliable architecture as our Ethereum ingestion.
That means: no CSVs, no complicated imports, just connect and you're done.
Here is how it works:
- Add your Base address
- We automatically detect your transactions
- We calculate your gains using FIFO in euros
- You get an accountant-ready PDF report
Fast, accurate and fully in line with Belgian rules.
DeFi on Base? Covered.
Swaps, bridges, staking, NFTs, 99.9% of the tokens on Base are recognized.
Our engine pulls the on-chain data directly, links every transaction to its euro value, and automatically applies the correct tax treatment.
Even complex DeFi flows, such as bridging between Ethereum and Base, are correctly recognized and classified, with no manual work.
Ready for other L2s
Base is only the beginning.
Thanks to our modular EVM architecture we keep expanding. Arbitrum is now fully supported too, and more networks will follow.
For you that means: one consistent report, no matter where you are active.
No more separate tools or duplicate calculations, just one platform, one clear overview.
