Comparing the best crypto tax software options for Australian users in 2025-26 — including Koinly (best overall), Syla (best value), CryptoTaxCalculator and others. What each costs and who each suits.
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 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.
| Detail | |
|---|---|
| Exchange support | 800+ exchanges and wallets including all major Australian platforms (CoinSpot, Swyftx, Independent Reserve, Binance AU) |
| ATO integration | Generates myTax-ready reports directly compatible with Australian lodgement |
| DeFi support | Good coverage of staking, lending, and liquidity pools |
| Pricing (from) | Free to import and preview; paid plans from approximately $59/year (Newbie) for up to 100 transactions, scaling up by transaction count |
| Best for | Users with activity across many exchanges, DeFi users, anyone who wants a polished, established platform |
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 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 support | Growing — covers all major Australian exchanges plus Binance, Coinbase, Kraken, OKX; more limited than Koinly for obscure platforms |
| Unique feature | LTFO (Lowest Tax First Out) optimisation — automatically calculates which lots to dispose of first to minimise your tax legally |
| Method comparison | Supports FIFO, LIFO, and HIFO side by side so you can see which saves the most |
| Pricing | Significantly cheaper than Koinly — check syla.com.au for current pricing; typically under $100/year for most users |
| Best for | Australians 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.
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 support | Best-in-class for complex Ethereum and DeFi activity |
| Exchange support | 3,500+ chains and wallets via smart contract data |
| Reports | Supports myTax and 20+ international jurisdictions |
| Pricing (from) | $49/year entry plan, scaling to $499 for high transaction volumes |
| Best for | Active DeFi users, NFT traders, anyone with complex on-chain activity |
For a quick estimate on individual transactions — or to sanity-check the figure before lodging — our free calculator handles the core CGT maths including the 50% discount, personal use exemption and capital loss offsets. It doesn't replace dedicated software for complex multi-transaction portfolios, but it's a useful first-pass tool that requires no account or signup.
Quick estimate for any single crypto disposal — no account required.

Similarly, providing a public wallet address is appropriate; providing a private key or seed phrase never is, to any service, for any reason. No legitimate tax platform will ask.
Consider revoking API keys once your return is lodged, and reissuing them next year. Also consider what happens to your transaction history if the provider is breached — your entire financial position across every wallet is a meaningful thing to expose.
A handful of straightforward disposals can be handled with a spreadsheet and a calculator. Paying an annual subscription for six transactions is not obviously sensible.
Significant DeFi, staking, or lending activity generally warrants a registered tax agent with crypto experience, using the software as an input rather than an authority. The treatment of these activities is fact-dependent and continues to develop.
Suspected errors in prior years should go to an agent before anything is lodged. Voluntary disclosure generally produces a better outcome than an ATO-initiated amendment.
Crypto tax software solves a real problem: converting hundreds of transactions across multiple platforms into Australian dollar cost bases and disposals. It does not solve the problem of incomplete data, and incomplete data is the cause of nearly every wrong answer.
Reconcile internal transfers, investigate every zero cost base, check that staking is classified as income, and confirm closing balances match your wallets. Use read-only API keys, and export your history regularly rather than trusting that an exchange will still exist next year.
Platform features, pricing, and integrations change frequently — verify current details directly with each provider. This page provides general information only and is not tax or product advice. Confirm your position with a registered tax agent before lodging.
A disposal is what triggers a CGT event — not withdrawing dollars. Swapping one coin for another is the case most often overlooked.
