Have you tried @summ_app? I had good luck with it but yeah definitely needs manual reviews but automates most of them.

For anyone else like me who nearly rage quit doing their crypto taxes, check out @summ_app. Totally saved my sanity...

That time of the year to go through transactions and make sure they are listed properly for tax purposes. Not fun when you have a lot of wallets but @summ_app makes it this much easier for you.

I literally could not function without [Summ]. I've got multiple assets on multiple blockchains doing 5-10k transactions a year. Doing that by hand would be pure insanity.

Just did my crypto taxes with [Summ] and got my report summary. Overall, very pleased with the process! Highly recommend if you have not yet decided on what crypto software to use. Did my taxes in a few hours and going to my tax guy tomorrow.

Called my tax accountant to warn him there will be some crypto and NFT stuff this year. His reply wasn't what I expected: “No worries, know all about them! My 13 yo daughter creates NFTs and sells them on OpenSea. And we use [Summ] for our clients” Boom! I chose well 💥💥

Unlike other tax items where you have to wait for 1099s' or bank statements, you can code all of your Crypto and Defi as soon as the ball drops on new years and get a good estimate of where your taxes lie. [Summ] is still my first recommendation for tools.
