Using the wrong crypto tax calculator could cost you more than you think
If you own crypto, calculating your tax isn’t simply a matter of subtracting what you paid from what you sold.
Your tax position depends on your complete transaction history, including transfers between wallets, token swaps, staking rewards and airdrops.
Generic tax calculators and manual spreadsheets may not reconstruct this history correctly, increasing the risk of reporting inaccurate figures in your tax return.
