Expensive for what it is.

App UI seems nice, but the UX is still complicated. Also it's very expensive for a simple calculation tool. I ended up just spent less than 30mins to vibe code the whole thing in figma make. Works flawlessly and free. The UX is arguably 10 times better too.

Difficult transactions

I had some transactions from a few years ago that were hard to resolve, so I reached out to the customer support team. Karl was great and helped me to work through each of the problems I had. Great experience overall and would recommend.

SUMM.com is by far the best crypto tax software out there, and I’ve used a few. Extensive integrations to import transactions from most every exchange. They also have an option to create custom CSV files to import transactions from legacy exchanges. Questions are quickly answered and one of their support representatives will spend quality time with you to straighten everything out. Thanks for your help Karl!

I would never recommend or use this company again, in their chat box you can request to talk to a human but then there is no response and no return information they don't post any kind of phone number anywhere so if you can get through the process without possibly having a snag where you need to ask a couple questions you'll be okay but otherwise total nightmare

I managed to input 5 years of data from multiple exchanges and wallets in one go to catch up on undeclared crypto transactions.A lot was manual input. Initially a daunting prospect, but once you become familiar with the app not so bad. Long and short the ATO was happy. Support was excellent. Shout out to Jena.
