# Best Crypto Tax Software Australia 2026
If you trade crypto in Australia, you have tax obligations. Every sell, swap, and spend is a capital gains tax event. With CARF reporting now live, the ATO has direct visibility into your exchange activity regardless of transaction size. The “they won’t notice” era is over.
Managing crypto tax manually is feasible if you made five trades on one exchange. It’s a nightmare if you’ve traded on multiple exchanges, used trading bots that generated hundreds of transactions, staked assets, or touched DeFi. Dedicated crypto tax software exists to solve this — connecting to your accounts, importing transactions, calculating gains and losses, and generating ATO-compliant reports.
Quick answer:
- Best overall: Koinly — broadest integrations, clean interface, flexible pricing
- Best for complex DeFi: Summ (formerly CryptoTaxCalculator) — deeper DeFi categorisation, Australian-made
- Budget option: CoinLedger — simpler tool, lower price point
Koinly — best overall
Koinly is the most widely-used crypto tax tool globally, and it works well for Australians. 800+ exchange integrations (including Swyftx, CoinSpot, Kraken, Binance), 170+ wallets, 7,000+ DeFi protocols, and ATO-compliant report generation.
The free tier tracks up to 10,000 transactions — useful for reviewing your portfolio and testing the tool before paying. Tax reports start at ~$69 AUD per tax year.
Strength: Breadth. If you use multiple platforms, Koinly almost certainly supports all of them.
Weakness: Complex DeFi interactions sometimes need manual correction.
Summ (CryptoTaxCalculator) — best for complex DeFi
Summ is Australian-made with 2,500+ DeFi integrations and partnerships with Coinbase and MetaMask. Where it edges ahead of Koinly is in granular DeFi categorisation — liquidity pools, yield farming, NFT trading, multi-chain bridging.
Pricing is subscription-based rather than pay-per-year, which suits some users better. The interface is clean and the Australian tax rule implementation is strong (as you’d expect from a local product).
Strength: DeFi depth and Australian-specific design.
Weakness: Subscription model can cost more for users who only need reports once a year.
CoinLedger — budget alternative
CoinLedger offers a simpler, more affordable option for users with straightforward trading histories. Fewer integrations than Koinly, but covers all major exchanges and generates ATO-compatible reports.
Best for: Users with simple trading histories on one or two exchanges who want a lower price point.

Which should you choose?
Most people: Start with Koinly’s free tier. Import your data and see if it categorises your transactions correctly. If it handles everything cleanly, pay for the tax report when you need it.
Deep DeFi users: Try both Koinly and Summ with your actual data. Complex DeFi is where categorisation differences show up, and which tool handles your specific protocols better depends on what you’ve used.
Simple traders: If you bought on one exchange and held, even Koinly’s free tier may be all you need. Or use CoinLedger for the lowest cost report.
