Work out what a purchaser must hold back at settlement and pay to the ATO where a vendor has not produced a clearance certificate.
Settlement position
What gets withheld at different sale prices
Since the threshold was removed, there is no longer a price below which withholding can be ignored. The single most valuable thing a vendor can do is apply for the clearance certificate as soon as the property is listed — it is free, valid for 12 months, covers multiple sales, and the ATO warns it can take up to 28 days.
Foreign resident capital gains withholding is designed to collect tax from non-residents selling Australian property. But the mechanism works in reverse: the purchaser must withhold from every vendor unless that vendor proves they are an Australian resident by handing over an ATO clearance certificate.
That means an Australian family selling their own home will have 15% of the price withheld if the certificate is not produced before settlement. There is no capital gain, no tax owing, and the money still goes to the ATO — recoverable only when the vendor lodges their return, potentially many months later.
Where there are several vendors on title, each one applies separately. One missing certificate exposes that vendor's share of the proceeds, not the whole price. Foreign residents cannot get a certificate at all, but can apply for a variation notice reducing the rate where 15% clearly exceeds the tax on the gain.
Residency for tax purposes is tested differently to residency for immigration or social security, and the purchaser carries the risk.
Important. Figures shown are estimates generated from the information you enter. They are not an assessment, a quote, or a statement of what you will actually pay.
The purchaser carries the withholding obligation. Penalties and interest apply if a purchaser fails to withhold when required, or fails to pay the amount to the ATO on the day of settlement. Withholding is a prepayment against the vendor's actual capital gains tax liability, not a final tax — the vendor claims a credit when they lodge their return. Residency for tax purposes is determined differently to residency for immigration or social security purposes.
