Do You Actually Need Dedicated Software?

If you've made fewer than 10-20 crypto transactions in a year (bought some Bitcoin, sold it once, maybe done one swap), you can calculate your capital gain manually from exchange exports and lodge via myTax without dedicated software. Our free crypto tax calculator handles the core CGT maths for individual transactions.

Dedicated crypto tax software becomes genuinely worthwhile when you have: frequent trades across multiple exchanges, DeFi activity (staking, liquidity pools, yield farming), hard forks or airdrops, transactions spread across multiple financial years, or you simply want an ATO-compliant tax report you can hand directly to an accountant without doing any manual calculations.

Koinly — Best Overall for Australians

Koinly is consistently rated the best overall crypto tax platform for Australian users, and its position is well-earned. It integrates with over 800 exchanges, wallets and blockchains — more than any competitor — which makes it particularly useful if you've used multiple platforms or held crypto across many wallets.

ATO integrationGenerates myTax-ready reports directly compatible with Australian lodgement
DeFi supportGood coverage of staking, lending, and liquidity pools

Limitation: Koinly uses FIFO (first in, first out) as its primary cost base allocation method and doesn't let you compare alternative methods side by side. For some investors, a different method (LIFO or HIFO) would produce a lower tax result, and Koinly won't show you that comparison.

Syla — Best Value for Australian Users

Syla was built specifically for Australian tax law by a team of Australian tax professionals including a Chartered Accountant, Chartered Tax Adviser, and Tax Lawyer. This focus on the Australian market shows in the quality of the ATO-compliant output and the tax optimisation logic.

Detail
Exchange supportGrowing — covers all major Australian exchanges plus Binance, Coinbase, Kraken, OKX; more limited than Koinly for obscure platforms
Unique featureLTFO (Lowest Tax First Out) optimisation — automatically calculates which lots to dispose of first to minimise your tax legally
Method comparisonSupports FIFO, LIFO, and HIFO side by side so you can see which saves the most
PricingSignificantly cheaper than Koinly — check syla.com.au for current pricing; typically under $100/year for most users
Best forAustralians trading on mainstream exchanges who want the best value and want to legally minimise their tax

Limitation: No DeFi or API sync yet as of 2026, and exchange coverage is narrower than Koinly. If you use obscure protocols or many different blockchains, Koinly may be necessary.

CryptoTaxCalculator (now Summ) — Best for DeFi

Originally founded in Australia and rebranded as Summ, this platform's major strength is handling complex on-chain DeFi activity — smart contract interactions, gas fees on failed transactions, NFT minting, and complex multi-step transactions that other platforms struggle to correctly classify.

Detail
DeFi supportBest-in-class for complex Ethereum and DeFi activity
Exchange support3,500+ chains and wallets via smart contract data
ReportsSupports myTax and 20+ international jurisdictions
Pricing (from)$49/year entry plan, scaling to $499 for high transaction volumes
Best forActive DeFi users, NFT traders, anyone with complex on-chain activity

Other Options Worth Knowing

What to Look For When Comparing Platforms

  1. Australian tax fit: Does it correctly apply the 50% CGT discount, handle crypto-to-crypto swaps as disposals, and generate a report in myTax format?
  2. Exchange compatibility: Can it import from the specific exchanges you've used? Check before signing up.
  3. Cost base methods: Does it support FIFO only, or can you compare FIFO, LIFO and HIFO? For some portfolios the difference is substantial.
  4. Preview before you pay: Most platforms let you import transactions and see your capital gains summary for free before charging for the final report. Use this to check the numbers look right before purchasing.
  5. DeFi support: Only relevant if you've done staking, liquidity pools, yield farming or NFT activity.
