# Koinly vs CryptoTaxCalculator (Summ) 2026 — Which Is Better for Australians?
Koinly and Summ (formerly CryptoTaxCalculator) are the two leading crypto tax tools for Australians. Both generate ATO-compliant reports, both support major Australian exchanges, and both handle the core job — calculating your capital gains tax from crypto trades — competently.
The difference shows up in the details: integration breadth, DeFi handling, pricing models, and edge cases.

The verdict
Choose Koinly if: You want the broadest exchange support, a generous free tier, and pay-per-year flexibility. It’s the better all-rounder for most Australian crypto users.
Choose Summ if: You’re deep into DeFi, NFTs, or multi-chain protocols. Its DeFi categorisation is more granular than Koinly’s, and being Australian-made means it understands local tax nuances natively.
Best approach: Import your actual transaction data into both free tiers. See which handles your specific history more cleanly. The answer depends on what platforms and protocols you’ve used.
