CoinJar tax calculator: estimate CGT on your CoinJar trades in Australia
CoinJar is an established Australian crypto exchange offering trading, swaps, and Earn products. If you have bought, sold, swapped, or earned through CoinJar during the 2025-26 tax year, each of those actions can have a different tax effect. This page explains what to expect and how to use the estimator with your CoinJar history.
Tax obligations for CoinJar users
Selling crypto for AUD on CoinJar, swapping one coin for another, or receiving CoinJar Earn rewards can all trigger taxable events under Australian law. Disposals — whether through sales or swaps — can create capital gains or losses. CoinJar Earn rewards are treated as ordinary income when received and create new parcels for future CGT calculations.
How to export your CoinJar transaction history
Log in to CoinJar and navigate to Settings, then select Tax Reports. Choose the relevant date range for the 2025-26 financial year (1 July 2025 to 30 June 2026) and click Download CSV to retrieve your full transaction history. This report includes trades, swaps, and Earn events. Keep this file for tax estimation.
Common taxable events on CoinJar
The most frequent tax-triggering actions for CoinJar users are: selling crypto for AUD (disposal), using CoinJar Swaps to exchange one cryptocurrency for another (disposal of the outgoing coin), and receiving CoinJar Earn rewards (ordinary income on receipt). The estimator handles each of these event types separately.
How to use this estimator with CoinJar data
After exporting your CoinJar CSV, enter your buy, sell, swap, and Earn events into the calculator using the event builder. The estimator applies FIFO parcel matching to calculate gains and losses. Make sure all values are entered in AUD — the estimator does not look up historical prices automatically.
Watch-outs for CoinJar users
CoinJar's built-in tax report may use a cost-base method that differs from FIFO — this estimator always uses FIFO, so your results may differ from CoinJar's own tax report if you have used a different method previously. Check that your Earn rewards are included in the export and entered as income events rather than acquisitions. Verify all AUD values match the actual trade prices at each transaction date.

Frequently asked questions
Do CoinJar Swaps trigger a capital gains tax event in Australia?
Yes. CoinJar Swaps involve exchanging one cryptocurrency for another, which is a disposal of the outgoing coin under Australian tax law. Any gain or loss is calculated based on the AUD market value of the outgoing coin at the time of the swap minus your cost base.
How is CoinJar Earn treated for Australian tax purposes?
CoinJar Earn rewards are generally treated as ordinary income at the AUD value on the date you receive them. Those received tokens also create a new parcel with a cost base equal to the income amount, which is relevant if you later sell them.
