If the 1 July 2027 cost base reset applies to you, timing is a fair question: you can’t value a date that hasn’t arrived, but you also don’t want to leave the evidence until it’s gone cold. Here’s how to think about when — calmly, not in a rush.
Why the value can only be finalised from 1 July 2027#
The reset sets your new cost base at your property’s market value immediately before 1 July 2027 — its value at the end of 30 June 2027 — which the law then treats as your acquisition cost on 1 July 2027. A value as at that moment can only be finalised once the date has passed — it reflects the market at that specific point. So the finished, signed report is produced from 1 July 2027; what you do before then is prepare and reserve, not finalise.
Reserve now, report from the date#
There are two separate things, and it helps to keep them apart:
- Reserving (or registering) records your intent and locks in the pathway. It costs nothing today and commits you to nothing — it simply means you’re organised and ready to go when the date arrives.
- The finished report is the signed valuation itself, assessed as at the end of 30 June 2027 — the moment just before 1 July 2027 that the law values your property at — and produced from 1 July 2027 onward.
You can reserve a dated valuation now with no payment, or register interest here for a reminder — then have the report finalised once 1 July 2027 has passed.
Contemporaneous evidence vs a later retrospective valuation#
You can value close to 1 July 2027, or you can commission a retrospective valuation years later. Both are legitimate — but they’re not equally easy to defend.
Evidence goes cold. Close to the date, the things a valuer relies on are fresh: comparable sales around 1 July 2027, the property’s condition, and your own records. Reconstruct that value three or five years later and those inputs are harder to pin down — comparable sales must be found in old data, the property may have changed, and memories fade. A contemporaneous valuation, captured around the date, is usually cleaner and easier to stand behind if questions arise later.
That’s not a reason to panic-book — it’s a reason to diarise 1 July 2027 and be ready to capture the evidence while it’s fresh.
Is a valuation even required?#
No — it’s a choice. A dated valuation is elective, but market value is the statutory default: the Treasurer’s free apportioning formula is the alternative, estimating the 1 July 2027 value by compounding a single growth rate across your whole ownership period. A signed valuation earns its keep when the formula would understate your real 1 July 2027 value, or when you want independently defensible evidence. How the two compare is set out at CGT cost base explained — and your accountant can say which fits each property.
Pricing#
Our value CGT option: on-site (full inspection) from $621 — a CGT cost base is a figure someone else will test, so that’s the level to use. Desktop from $269 involves no inspection and suits lower-stakes purposes. Registering costs nothing today. Prefer the premium, defensibility-first path? Reserve at CGT Valuation Ready.
