Frequently asked questions

Quick answers to some of your most common questions.

How is crypto tax calculated in the United States?

You can be liable for both capital gains and income tax depending on the type of cryptocurrency transaction, and your individual circumstances. For example, you might need to pay capital gains on profits from buying and selling cryptocurrency, or pay income tax on interest earned when holding crypto.

I lost money trading cryptocurrency. Do I still pay tax?

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.

How do I calculate tax on crypto-to-crypto transactions?

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.

How can Summ help with crypto taxes?

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.

Can't I just get my accountant to do this for me?

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.

Does Summ handle non-exchange activity?

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.

Do I have to pay for historical tax reports?

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.

Can I use my own accountant?

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.

How does payment work?

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.

What if my exchange is not on the list of supported exchanges?

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.

Does Summ support NFT transactions?

We do! Summ integrates with many NFT marketplaces and offers categorization options for any NFT-related activity (minting, buying, selling, trading).

How does the free trial work?

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.

what your 1099 is missing

One exchange. One snapshot. Not your complete tax picture.

Image

No exchange data
It won’t show activity on other exchanges

Image

No on-chain visibility
It can’t see wallets or most on-chain activity

Image

No cost basis history
It doesn’t know your original cost basis

The three real risks when filing off a 1099-DA

01

Mismatch risk

Filing numbers that don’t line up with what the IRS received from exchanges.

ImageImage

02

Overpayment risk

Missing cost basis defaults against you, often inflating taxable gains.

ImageImage

03

Assumed cost basis risk

Treating incoming crypto as a market-price purchase with no supporting evidence, just to force clean numbers.

Don’t overpay on your tax

Reconcile before you file.

1099-DA reflects what one exchange reported. It does not reflect your full crypto history.
