2021/2022 taxes completed and paid. Use your bear market time wisely. Big shoutout to @CryptoTaxHQ, second year running I've used them. I've tried a few of these calculators and CTC blow their competitors out the water.

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

A cryptid is tentatively back from hiatus but will be keeping update frequency low rn. Uncle Sam unretired me 4 a mission to JPN so had to finish taxes early. Got it done thx to #CryptoTaxCalculator (@CryptoTaxHQ). I have no affiliation w/ them. Pls just keep it alive🙏

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. @CryptoTaxHQ is still my first recommendation for tools.

CTC has a really good Reconcilliation section where it flags up issues and presents them in logical order so you can tick them off one by one. It's still work but it's just more intuitive I found

Not sponsored or anything but came across CryptoTaxCalculator.io @CryptoTaxHQ. Such an easy way to track and record your crypto taxes automatically. Made tracking my Binance spot/futures trades + Uniswap transactions a whole lot less daunting.

Just did my crypto taxes with @CryptoTaxHQ 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 @CryptoTaxHQ for our clients” Boom! I chose well💥💥
