Get your 1 July 2027 cost base wrong, and you could overpay CGT.#
From 1 July 2027 your property’s cost base resets to its market value on that date. Set it too low and you hand the ATO more than you need to. See how the reset works — and how a dated valuation protects you.
The mechanics#
Gains up to 1 July 2027 keep the old 50% discount; gains after are taxed under indexation + a 30% minimum, measured from your 1 July 2027 value. The higher and better-supported that value, the lower your future taxable gain — so a dated, independent valuation (vs the ATO’s apportionment formula) can change your tax materially. General information, not tax advice — confirm with your accountant.
Pricing#
Standard desktop (no inspection) from $349; on-site (full inspection) from $790. Inc GST, indicative. A 1 July 2027 valuation done later is retrospective (+$150).

General information only — not tax, financial or legal advice. Any indicative appraisal is automated and is not a certified or ATO-suitable valuation; the signed valuation is provided separately. cgtcostbase.com.au is a property-valuation service operated by Xcelerent.
