Introduction
The 6-Year Capital Gains Tax (CGT) Rule is one of the most valuable tax strategies available to property owners. When used correctly, it can help you significantly reduce — or even eliminate — the tax payable when selling your property.
What is the 6-Year Rule?
The 6-year rule allows you to treat a property as your main residence for tax purposes, even after you move out of it. This means you may still be eligible for a full CGT exemption for up to 6 years, even if the property is rented out during that time.
How It Works
- You must have lived in the property as your main residence first
- After moving out, you can rent the property
- You can continue to treat it as your main residence for up to 6 years
- If you sell within this period, you may avoid paying CGT
Key Benefits
- Reduce or eliminate capital gains tax
- Turn your home into an income-generating asset
- Maintain flexibility when upgrading or relocating
Important Considerations
- You cannot claim another property as your main residence at the same time
- If you hold the property longer than 6 years while renting, partial CGT may apply
- Proper record-keeping is essential
When Should You Use It?
The 6-year rule is ideal if you:
- Move out and rent your home
- Relocate temporarily for work
- Upgrade to a new home but keep your existing property as an investment
Final Thoughts
The 6-Year CGT Rule can be a powerful wealth-building tool when used strategically. However, applying it correctly depends on your individual situation, so professional advice is essential.
