We do not report anything to the IRS. All transactions are on-chain, so you can use whatever crypto tools you already use for taxes, e.g. Zenleger, TaxBit, Cointracker.
If you’re using stablecoins like USDT, USDC, DAI, there should be little to no taxes since the price doesn’t fluctuate. If you’re using ETH or BTC or something that fluctuates, interacting with Spritz is just like using a DEX like Uniswap — you’re selling your tokens. So you’ll have a gain or tax loss depending on where you originally bought the token.
