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.

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.

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 💥💥

Frequently asked questions

Quick answers to some of your most common questions.

No. Use it for both, or just one. Summ produces a report ready for your tax return, whatever you hold.

Generally two ways. Capital gains tax applies when you sell or dispose of an asset, such as selling shares or swapping one crypto for another. Income tax applies to what you earn, such as dividends or interest on crypto. How each transaction is treated depends on its type and your circumstances. Summ applies the ATO's rules to each one and shows how every figure is worked out.

Yes. Summ supports dividends and distributions, share splits and consolidations, capital returns, demergers, mergers, ticker changes and special dividends. For ETFs and managed funds, upload your AMMA statement and confirm the cost base adjustment Summ reads from it. Franking credits and foreign income sit in the same ATO-ready report as the rest of your portfolio.

We do. We have integrations with many NFT marketplaces, and categorisation options for any NFT activity: minting, buying, selling and swapping.

Yes, Summ (formerly Crypto Tax Calculator) is designed to generate accountant-friendly tax reports. You import your transaction history and export your report, so your books are up to date before your accountant sees them, which can reduce the bill. You can discuss tax scenarios with your accountant and have them review the report.

We have an annual subscription which covers all previous tax years. If you need to amend your tax return for previous years, you're covered under the one payment.

There's no time limit. Summ is free to use from the moment you sign up: import your accounts, track your portfolio and use the categorisation tools at no cost. You only need a paid plan when you want to download your reports or use premium features such as tax loss harvesting.
