Do I need a property valuation at 1 July 2027? (CGT changes checker)

Last reviewed 13 October 2026 · General information, not advice

From 1 July 2027, Australia replaces the 50% capital gains tax discount with indexation for individuals, trusts and partnerships. Property you still own on 30 June 2027 is treated as sold and bought back at its market value on 1 July 2027 — so that value becomes a key number when you eventually sell. Answer five questions to see whether a valuation is likely to matter for you.

1. Who owns the property?
2. Will you still own it on 30 June 2027?

If you sign a sale contract before 1 July 2027, answer No.

3. Has it been your main residence the whole time you've owned it?

And do you expect it to stay that way?

4. When did you buy it?
5. Are you an Australian resident for tax purposes?

Answer all five questions to see the result.

Records worth keeping either way

  • The purchase contract and settlement statement (your original cost base).
  • Invoices for capital improvements since you bought it, with dates.
  • A registered valuer's report dated as close to 1 July 2027 as possible. A bank valuation isn't a substitute.
  • For overseas property, the official exchange rate and date used to convert values to AUD.
  • The dates the property was your home, rented, or vacant.

What's still pending

As at the review date, the law allows the Minister to set an alternative method to market value for splitting the gain, and the ATO has announced valuation tools — neither had been published yet. The definition of a “new residential dwelling” (new builds can elect to keep the 50% discount) also depends on a ministerial instrument. We update this page when they appear.

Common questions

When should the valuation be dated?

As close to 1 July 2027 as practical. A valuer can also prepare a retrospective valuation as at that date later, but evidence gathered at the time is usually stronger and cheaper.

Does this change the main residence exemption?

Not that we can see in the published material. A home that is fully your main residence the whole time you own it is usually still exempt.

What about negative gearing?

Separately, from 2027–28 rental losses on residential property bought after 7:30pm AEST on 12 May 2026 (other than new builds) can no longer reduce your other income. See the guide.
