Is there a free crypto tax calculator? There are three answers here. Yes, no, and we have discount codes to some really good ones that make them cheaper.

If you’ve dabbled in any cryptocurrency trading this financial year in Australia, you'll need to consider the tax implications.

Any cryptocurrency transaction, including buying, selling, trading, mining, staking, giving, or receiving, must be reported on your tax return. This requirement applies regardless of where the transaction occurred — be it Australia, the United States, or even a remote tax haven in the Pacific.

Essentially, if you’ve used crypto, the tax man wants to know about it.

However, calculating your cryptocurrency tax can be complex, with various factors to consider when preparing your tax return.

There is a really comprehensive article here if you want to speed up your knowledge before you choose a crypto tax calculator.

Does the ATO track your crypto trades?

Yes, the ATO closely monitors cryptocurrency transactions through its crypto-assets data matching program, which has been in place since the 2014-15 financial year.

It’s crucial to keep accurate records of these transactions. All Australian crypto exchanges that are registered with AUSTRAC are required by law to share data with the ATO.

Free crypto tax calculator / Free crypto tax software

Are there free crypto tax calculators? Yes, there are. But unfortunately, the most well-known one, has been retired.

Free trial periods

There are crypto tax software companies that have free trial periods and offer free initial calculations. But to do anything meaningful, you are going to need to get a subscription to one of the companies that offer crypto tax calculators.

So your best bet is to actually subscribe to a paid service. The good news here is that we have some discount codes for you.

Automate your tax return

Crypto accounting apps like Summ, Koinly, Syla, Koinx, and CoinLedger can help. These programs track all your transactions in real-time, regardless of where and when they occur.

At the end of the financial year, they compile your transaction history into a document that details your capital gains and losses in Australian dollars. This makes it easier to assess your tax obligations and monitor your overall portfolio performance.

CoinJar now offers full, secure transaction integration with multiple crypto tax calculators. This means any cryptocurrency transaction conducted on CoinJar will be directly transferred to your chosen crypto tax software account. This means you will be ahead of the game at tax time.
