Understanding Cost Base for Australian Capital Gains Tax
The cost base is the total amount you paid to acquire, improve, and sell an asset. It directly impacts your capital gains tax liability in Australia. This guide explains how to calculate it correctly.
Key Components of Cost Base
- Purchase Price: Original cost of acquiring the asset (e.g., property, shares)
- Improvements: Costs for renovations, extensions, or upgrades that increase value
- Incidental Expenses: Fees like legal costs, stamp duty, and agent commissions
- Sale Costs: Advertising, legal fees, and auctioneer fees related to disposal
Cost Base Calculation Example
| Component | Amount ($) |
|---|---|
| Property Purchase Price | 500,000 |
| Renovation Costs | 30,000 |
| Stamp Duty | 15,000 |
| Total Cost Base | 545,000 |
Important Notes
The 50% capital gains tax discount applies if you owned the asset for more than 12 months. Non-residents and certain assets (like collectibles) may not qualify for this discount.
