CGT — Capital Gains Tax

Capital Gains Tax (CGT) isn't a separate tax — it's part of income tax. Net capital gains for the year are added to your assessable income and taxed at your marginal rate. Whether you owe CGT and how much depends on what was sold, when, and how long you held it.

1. What triggers CGT

Selling a CGT asset (shares, crypto, investment property, business assets, collectibles over $500) is the main trigger. So is gifting one, transferring it on relationship breakdown (with rollover available), or having it destroyed without insurance. Disposing of your main residence is usually exempt — but not always.

2. The 50% discount

Individuals and trusts that hold a CGT asset for more than 12 months get a 50% discount on the resulting gain. Companies don't get the discount — they pay tax on the full gain at the company rate. Self-managed super funds in accumulation phase get a 33⅓% discount; in pension phase, gains can be tax-free.

3. Main-residence exemption

Your main residence is generally CGT-exempt while you live in it. Complications: working from home and claiming a portion (partial loss of exemption), renting it out for a period, owning it for less than the period it was your main residence, or owning multiple properties. The 'six-year rule' lets you treat a former main residence as still your main residence for up to six years of absence in many cases — useful for FIFO workers and military families.

4. Crypto, shares, NFTs

Every disposal is a CGT event. 'Disposal' includes crypto-to-crypto trades, swapping one token for another, and using crypto to pay for goods. Buying coffee with Bitcoin is a CGT event on the coffee. Records of every transaction with date, amount and AUD value at the time are required — software like Koinly or CoinTracking is usually worth the cost for active traders.

5. Common mistakes

· Treating the buy-sell as a single transaction without tracking the cost base correctly (purchase price + brokerage + improvements + holding costs) · Forgetting that CGT applies to crypto-to-crypto swaps even when no AUD changes hands · Claiming the main-residence exemption on a property that was rented out without applying the partial exemption rules · Missing the small-business CGT concessions when selling a business — these can reduce or eliminate the gain entirely if you qualify · Realising losses without applying them against gains in the same or future years (carry-forward is straightforward but only if reported)

6. When to talk to us

Before selling, ideally. CGT planning months or years in advance often reduces the gain — through timing, structure, or applying the small-business concessions. For crypto, we work with your transaction history regardless of which platform. CGT calculations are quoted at $99 per event added to a personal return, or scoped separately for complex business or property disposals.
