Australian Crypto Tax Calculator

Use this free Australian crypto tax calculator to estimate the capital gain on a disposal under ATO rules. It opens with Australia already selected and works in Australian dollars. Because the acquisition date of each parcel decides whether the 50% CGT discount applies, enter the dates as well as the amounts — that field is doing more work here than in most countries.

This calculator produces an estimate for general information, not tax advice, and covers one disposal at a time. Australian treatment depends on your circumstances, including whether you are an investor or a trader. Confirm your position with the ATO or a registered tax agent.

How the Australian crypto tax calculator works

The calculator above is already set to Australia. Add a row for each parcel you acquired of the asset you disposed of, with the quantity, the price you paid per unit and the date you acquired it. Then enter the quantity you disposed of and what you received. The estimate is the gain on that disposal, in Australian dollars.

The acquisition date is not bookkeeping here. Whether a parcel was held for more than 12 months decides whether half the gain on it is taxed or all of it, so an estimate built without dates is not an Australian estimate. This is also the single most common thing crypto tax tools lose, because a transfer between your own wallets looks like a new acquisition unless the tool is built to carry the original date across.

The country picker stays usable. If you landed here but file elsewhere, change it rather than hunting for another page.

CGT events the ATO taxes

A disposal in Australia is broader than selling to cash, which is why active traders usually have far more taxable events than they expect:

Swapping one crypto asset for another

A swap is a CGT event on the asset you gave up, valued in Australian dollars at the time, with a new parcel opened for what you received. Staying in crypto does not defer anything.

Spending or gifting crypto

Paying for goods or services with crypto is a disposal, and so is gifting it. Neither produces cash in a bank account, which is exactly why they are the events most often missed.

Wrapping and unwrapping tokens

Wrapping a token is a CGT event and it resets the 12-month clock for the new asset. If your history runs through wrapped assets, the discount you expect on a long-held position may not be there.

There is also a limited personal use asset exemption that can, in narrow circumstances, apply to crypto acquired for under $10,000 and used to buy personal items. It is far narrower than people hope and is not a general small-transaction exemption; check it with a registered tax agent rather than assuming it.

AUD cost base with FIFO and specific identification

Your cost base is in Australian dollars, converted at the time of each acquisition and each disposal. If you traded on an offshore venue in US dollars or a stablecoin, that conversion happens on every leg rather than once at year end, and getting it wrong moves every number downstream.

The calculator lets you choose how disposals draw on your parcels, so the estimate reflects the approach you are actually applying rather than the only one the tool offers. The mechanics of each method are in the cost basis guide.

Applying the 50% CGT discount after 12 months

Hold a crypto asset for more than 12 months before disposing of it and, as an individual, only half the capital gain is added to your taxable income. Held for 12 months or less, all of it is. This is the largest legitimate lever in an Australian crypto return, and it is decided parcel by parcel rather than per coin.

So if you bought the same token on four dates and sold part of your holding, the discount depends on which parcels the disposal drew from and how long each had been held. Enter the parcels separately in the calculator above and the dates will do their job. Traders whose activity is business-like rather than investment do not get the discount at all, and profits are ordinary income instead.

Staking and airdrops as ordinary income

Staking rewards and airdrops are generally ordinary income at their value when you received them, not capital gains. They belong in the income section of your return, and the amount you declare also becomes the cost base of the units you received.

That second half is the part estimates get wrong. If you enter reward units in the calculator with a zero cost, you tax yourself twice: once as income at receipt and again on the full proceeds at disposal. Enter them at the value they had when you received them.

Your marginal tax rate on the net capital gain

Australia has no separate capital gains tax rate. The net capital gain, after the 50% discount where it applies, is added to your taxable income and taxed at your marginal rate. This calculator does not ask for your income and so does not apply a rate to the result — treat the gain as the output and apply your own.

Capital losses offset capital gains, and it is the net figure for the year that is discounted and added to your income. A single-disposal estimate cannot see your other disposals, so a gain shown here may be reduced by losses elsewhere in the same year.

From estimate to myTax lodgement

You declare crypto in your annual return, through myTax or a registered tax agent: capital gains in the capital gains section, reward income as ordinary income. The income year runs 1 July to 30 June, and the deadline is 31 October if you lodge yourself, generally later through a registered tax agent.

CryptaTax imports your exchanges and wallets, tracks the holding period of every parcel across transfers, applies the discount where the parcel qualifies, and produces the figures in Australian dollars ready for myTax with each number traceable to its transaction.
