Our verdict
Calculate your crypto taxes for previous tax years for an annual subscription.
Summ is different from other crypto tax software in Australia as it uses a subscription-based model for its pricing rather than a year-to-year payment structure. That means you can import your crypto history for 1 year, or go back as far as 2013 and get a tax report for each year for the same annual price.

T&Cs and limits apply.
While Summ may be a good option to calculate your cryptocurrency taxes for previous years, it's not a long-term, cost-effective solution because of its rolling transaction limit. Unlike most crypto tax software that resets the transaction limit for each tax year, Summ has a cumulative lifetime limit.
The cumulative nature of this limit means that your transactions each year count toward your limit. So if you have 90 trades in 2021 and 11 in 2022, you would need to upgrade your account from Rookie to Hobbyist because you've exceeded the Rookie's 100-transaction limit.
Ultimately, you must continually upgrade your account the longer you use the service, making it one of the pricier crypto tax software programs in Australia in the long run.
Pros
Up to 1,000,000 transactions. Summ's plans for high-volume traders allows you to track and report up to 1,000,000 transactions.
30-day money-back guarantee. If Summ isn't the right fit, you can cancel your plan and request a refund from customer support.
DeFi integrations. Summ supports just under 3,000 DeFi protocols and services which is sure to satisfy even the biggest on-chain traders.
Cons
No free plan. You can try the platform for free and import data, but you will need to pay to receive a calculated report.
Transaction limit is for all tax years. Summ counts all your trades for all tax years against your transaction limit. That means you'll need to continually upgrade your account as you inch closer to your transaction threshold each year.
No cryptocurrency payment. Since Summ uses a subscription model, it doesn't accept cryptocurrency payments yet. Your billing method is limited to credit cards as opposed to other crypto tax software that also allows you to pay with a bank transfer and some cryptocurrency.

Expert insight
"Crypto tax software usually requires you to upload and reconcile your trade history from wallets and exchanges before giving you a summary report. Summ goes a step further and auto-imports your transactions, categorising complex DeFi and NFT transactions as per Australian rules. It then creates a personalised tax report for easy filing with the ATO or an accountant."

How safe is Summ to use?
Summ only asks for read-only permissions with APIs, so it can't make changes to your cryptocurrency portfolio. Plus, no one on its support team can access details on your account.

Summ reviews and complaints
Summ earns 4.7 out of 5 stars on TrustPilot based on 618 reviews. Customers praise Summ for its responsive customer support, citing quick replies via live chat, instructional video recordings and implementation of customer feedback.
The only complaint was that customers still had to make manual adjustments after importing data, which is to be expected of any crypto tax software.

Finder is a comparison service. We do not compare every product or every provider in the market.
We make money through commercial arrangements with some of the providers on this site. Products marked 'Sponsored', 'Promoted', 'Featured' or 'Advertisement' appear as a result of a commercial arrangement.
Our editorial content, product reviews and any 'Top Pick' designations are prepared independently of these commercial arrangements.
The default order of products in our tables can be influenced by commercial arrangements. You can re-sort or filter using the controls above each table.
Some content on this site may be generated or supported by AI tools. You should verify details directly with the provider.
Finder is one of Australia's leading comparison websites. We are committed to our readers and stand by our editorial principles.
Our comparison service does not include every product or every provider in the market. Some product issuers offer their products under multiple brands or through associated companies. Where we can, we identify the underlying issuer so you can compare like with like, but you should always check with the provider directly to confirm which brand you are dealing with.
Finder is a comparison website and an intermediary. We are not a product issuer and we do not provide personal financial or credit advice. When you click a link to a product, or apply for a product through our site, you deal directly with the product issuer. We may receive a referral fee, commission or other payment from the issuer if you click through, apply or take out a product. We describe these arrangements in more detail under 'How we make money' below.
Product features, fees, terms and eligibility criteria are set by the product issuer and may change. We rely on information supplied by issuers when we present product details on our site. Before you apply for or take out any product, you should confirm the details directly with the issuer.
We earn revenue from Finder in four principal ways:
Referral fees and commissions. When you click a product link, complete an enquiry form or apply for a product through our site, we may receive a referral fee, commission or other payment from the product issuer. We may also receive payment based on the volume of leads or conversions we send to an issuer.
Sponsored placements. Products marked 'Sponsored', 'Promoted', 'Featured' or 'Advertisement' appear as a result of a commercial arrangement between Finder and the issuer. These labels always indicate a paid placement. We do not use them for editorial choices.
Display advertising. Banner advertising, newsletter advertising and similar display ads on our site are paid by advertisers.
Content sponsorship. Some articles, videos and social media posts are sponsored by an issuer and are clearly labelled as such.
Our editorial opinions, product reviews and any 'Top Pick' designations are prepared independently of these commercial arrangements. A 'Top Pick' is an editorial choice made by our writers and editors based on the criteria described on each comparison page. A 'Top Pick' is not a personal recommendation and does not mean the product is appropriate for your circumstances.
If you would like to know whether we have a commercial arrangement with a specific product issuer, please contact us.
When products are grouped in a table or list, the default order can be influenced by commercial arrangements we have with product issuers. In some categories, sponsored or featured products appear in the top positions of the table by default, and are always labelled as such.
Other factors that influence default order include price, fees and features, and (where relevant) our editorial view of the product.
You can re-sort every comparison table using the controls above the table. You can filter by product features that matter to you. The order you see after re-sorting or filtering is not influenced by commercial arrangements.
