Clear Tax Explains the 6-Year Rule to Help Australians Reduce Capital Gains Tax

MELBOURNE, Australia - Feb. 20, 2026 - PRLog -- Clear Tax is urging Australian property owners to review their capital gains tax position before selling, highlighting the often misunderstood 6-year rule that can legally eliminate or reduce CGT.

With property values rising across Australia, selling can trigger a significant tax bill. Yet many homeowners are unaware that a former main residence can remain CGT-free for years, even while rented out.

Understanding Capital Gains Tax

Capital gains tax applies when you sell an investment property for more than you paid. The gain is added to your taxable income in that year. If held for more than 12 months, individuals may access the 50 per cent CGT discount.

What Is the 6-Year Rule?

If you move out of your home and rent it out, you may still treat it as your principal place of residence for up to six years. During that period, you can earn rental income, claim deductions, and still pay no CGT when you sell, provided you do not treat another property as your main residence.

Imagine relocating for work. You rent out your home for five years, then sell within that six-year window. The entire capital gain may remain tax-free.

"This rule is completely legal and backed by the ATO, yet many owners either miss it or apply it incorrectly," says Ash Jindal, Director and Co-Founder of Clear Tax. "We often see people pay tax they did not need to."

What Happens After Six Years?

If the property is rented beyond six years, the exemption becomes partial. Only the rental period exceeding six years is taxable. Importantly, the cost base resets to the market value when the property first became a rental.

That adjustment can significantly reduce the taxable gain. The 50 per cent CGT discount may still apply if ownership exceeds 12 months.

Resetting the Clock

If you move back into the property and genuinely live in it again, the six-year period can reset. However, the ATO expects real evidence of residency. Changing your mailing address alone is not enough. Utility bills, electoral records, work location, and day-to-day living patterns all matter.

"The ATO looks at intent and behaviour," Jindal explains. "If your move is genuine, you are protected. If it appears staged, it may attract scrutiny."
