Essential ATO guide on calculating Capital Gains Tax for stocks, shares, crypto, ETF distributions, First-In First-Out (FIFO) parcel matching, and 50% discount rules.
- ✓Disposing of shares, ETFs, or cryptocurrency triggers a CGT event in the financial year the contract or swap occurs.
- ✓Holding share parcels or crypto assets for longer than 12 months (365 days) unlocks the statutory 50% CGT discount.
- ✓Taxpayers can choose individual share parcel matching methods (FIFO, LIFO, or Highest In First Out) to minimize taxable net capital gains.
- ✓Capital losses from stock or crypto trading can ONLY offset capital gains—they cannot be deducted against ordinary salary income.
- ✓Carried-forward capital losses never expire and must be offset against gross capital gains BEFORE applying the 50% CGT discount.
Investing in Australian equities (ASX stocks), Exchange-Traded Funds (ETFs), international shares, and digital assets (cryptocurrency) is a major wealth builder. Under Australian Taxation Office (ATO) legislation, any disposal of shares or crypto triggers a Capital Gains Tax (CGT) event under Part 3-1 of the *Income Tax Assessment Act 1997*.
This guide explains parcel matching methods, capital loss carry-forward rules, ETF AMMA tax statements, and the 50% CGT discount.
1. When Does a CGT Event Occur on Shares & Crypto?
A reportable CGT event occurs whenever you:
- 1Sell shares or crypto for fiat currency (e.g. AUD).
- 2Swap one cryptocurrency for another (e.g. BTC to ETH).
- 3Gift or transfer ownership of shares or crypto to another person.
- 4Use crypto to pay for goods or services (unless qualifying under personal use asset rules below $10,000).
2. Share Parcel Matching Methods: FIFO, LIFO & HIFO
When you buy shares or crypto in multiple tranches at different prices, the ATO permits investors to choose which specific asset parcels are sold.
3 Main Parcel Selection Methods:
- •First-In, First-Out (FIFO): Assumes the oldest shares bought are the first sold.
- •Highest-In, First-Out (HIFO): Sells highest cost parcels first to maximize cost base and minimize immediate capital gain.
- •Specific Parcel Selection: Specifically identifies parcels held for >12 months to maximize 50% CGT discount eligibility.
3. ATO Capital Loss Offsetting Rules
If you sell shares or crypto at a loss, you generate a capital loss.
Strict Statutory Loss Rules:
- •Capital losses CANNOT be offset against your salary, wages, or business income.
- •Capital losses MUST be subtracted from gross capital gains in the current financial year.
- •Unused capital losses carry forward indefinitely to future tax years.
- •Capital losses are subtracted BEFORE applying the 50% CGT discount!
