From www.codea.com.au: Effective January 1, 2025, all owners of taxable Australian real property must obtain a tax clearance certificate from the ATO to confirm their tax residency status before selling their property.

Failure to provide this certificate at the time of settlement requires the purchaser to withhold 15% of the sale price and remit it to the ATO.

The new regulations expand the requirement to all property sales, with no minimum sale price threshold, increasing the potential financial impact on sellers.
