Summ — frequently asked questions
Does Summ work for Australian crypto tax?
Summ produces an ATO myTax-ready report and applies Australian rules such as the 50% CGT discount. It is Australian-owned and built around the ATO.
How much does Summ cost? Is there a free tier?
Summ has a free tier — full platform, portfolio & defi/nft; pay to download reports. Paid plans run from about A$49/yr up to around A$399/yr (transaction limits are cumulative (lifetime), not reset each year).
Does Summ support Australian exchanges?
Yes — CoinSpot, Swyftx, Independent Reserve, BTC Markets, CoinJar, Cointree. In total it offers 3,500+ integrations — 160+ exchanges, 510+ wallets, 2,300+ defi protocols, via both API and CSV import.
Is Summ accurate?
Summ's figures are only as good as the data you feed it — accuracy depends on importing every wallet and exchange so transfers aren't mistaken for sales. It has advanced DeFi and NFT handling. For complex situations, have a registered tax agent review the report.
Do I actually need crypto tax software?
It isn't legally required, but the ATO receives transaction data directly from Australian exchanges, so your activity is visible to them. If you use more than one exchange or wallet, or have many transactions, a tool like Summ saves hours and reduces errors. A handful of simple trades can be worked out by hand.
