 CoinTracker has an excellent tax guide if you'd lke more details on the subject: https://www.cointracker.io/blog/crypto-tax-guide
 
 Koinly is an excellent choice as well. There are pros/cons to all of these sites and with varying fees & features. They're worth a look.
 
+TokenTax is another simple and easy to use option, but comes at a cost. The report generated from this tool tracks "Deposits", "Withdrawals" and "Staking" income. Combined with
+data one's other wallets/exchanges, TokenTax can show captial gains as well as income received from Algorand staking.
