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.

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.

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 💥💥

Frequently asked questions
Quick answers to some of your most common questions.
The way cryptocurrencies are taxed in most countries mean that investors might still need to pay tax, regardless of whether they made an overall profit or loss. Depending on your circumstances, taxes are usually realized at the time of the transaction, and not on the overall position at the end of the financial year.
In most countries you are required to record the value of the cryptocurrency in your local currency at the time of the transaction. This can be extremely time consuming to do by hand, since most exchange records do not have a reference price point, and records between exchanges are not easily compatible.
You just need to import your transaction history and Summ (formerly Crypto Tax Calculator) will help you categorize your transactions and calculate realized profit and income. You can then generate the appropriate reports to send to your accountant and keep detailed records handy for audit purposes.
We always recommend you work with your accountant to review your records. If you would like your accountant to help reconcile transactions, you can invite them to the product and collaborate within the Summ web app. We also have a complete accountant suite aimed at accountants.
Summ (formerly Crypto Tax Calculator) handles all non-exchange activity, such as onchain transactions like Airdrops, Staking, Mining, ICOs, and other DeFi activity. No matter what activity you have done in crypto, we have you covered with our easy to use categorization feature, similar to Expensify.
Our subscription pricing is per year not tax year, so with an annual subscription you can calculate your crypto taxes as far back as 2013. The process is the same, just upload your transaction history from these years and we can handle the rest.
Yes, Summ is designed to generate accountant-friendly tax reports. You simply import all your transaction history and export your report. This means you can get your books up to date yourself, allowing you to save significant time, and reduce the bill charged by your accountant. You can discuss tax scenarios with your accountant, and have them review the report.
Summ has an annual subscription which covers all previous tax years. If you need to amend your tax return for previous years you will be covered under the one payment.
Summ covers thousands of exchanges, wallets, and blockchains, and DeFi apps, but if you do not see your exchange on the supported list we are more than happy to work with you to get it supported. Just reach out to [email protected] or via the in-app chat support feature and we will get you sorted.
We do! Summ integrates with many NFT marketplaces and offers categorization options for any NFT-related activity (minting, buying, selling, trading).
Summ is free to use immediately upon signup, allowing you to import your transactions and take advantage of our smart suggestion and auto-categorization engine, portfolio tracking, DeFi and NFT support. For access to reports, the tax loss harvest tool or chat and priority support, you will need to upgrade to the appropriate paid plan.
