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.

How is crypto tax calculated in Australia?

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.

How does payment work?

We have 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.

Can I use my own accountant?

Yes, Summ (formerly Crypto Tax Calculator) 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.

Do you support NFT transactions?

We do! We have integrations with many NFT marketplaces, as well as categorisation options for any NFT related activity (minting, buying, selling, trading).

How does the free trial work?

The platform is free to use immediately upon signup, allowing you to import your transactions and take advantage of our smart suggestion and auto-categorisation 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.

How Summ works

Step 01

Connect accounts

Link your exchanges and wallets using read-only access.

Step 02

Review what’s missing or mismatched

Summ matches activity across platforms and flags gaps in cost basis or history.

Three transaction cards showing: Buy 1.142 Ethereum on 16 Oct 2024, Transfer 3.636 Bitcoin on 01 Nov 2024, and Trade 2.192 Solana on 22 Nov 2024.

Step 03

Generate an explainable
tax report

Your report reflects what actually happened. Clear. Defendable.

Get started for free

Secure connections you can trust

Summ uses read-only access.
We can’t move funds. We can’t place trades. We can’t change anything.

Your data is used to reconstruct what actually happened.  Nothing more.

Read-only access to exchanges and wallets

No ability to withdraw or trade

Trusted by Coinbase users and tax professionals

backed by leading security standards

Reconcile before you file.

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

Once assets move between platforms or on-chain, the data fragments.

Reconciliation connects the dots before you lock numbers into a return.

what your 1099 is missing

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

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

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

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.

02

Overpayment risk

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

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.

Once assets move between platforms or on-chain, the data fragments.

Reconciliation connects the dots before you lock numbers into a return.

Identify wallets or exchanges that aren't included yet.

Catch data issues early

Surface gaps, missing periods, and inconsistent exchange data.

Focus on what matters

Four steps to filing with confidence

01

Connect every wallet and exchange your 1099-DA can’t see

03

Fix gaps that actually change your tax outcome

04

File with a defendable report you can stand behind
