Am I Affected by the 2027 CGT Changes? Self-Check

The 2027 CGT changes are now law (Act No. 49 of 2026, assented 26 June 2026), but they don’t touch everyone the same way. Before you do anything, it’s worth two minutes to work out whether the 1 July 2027 cost base reset is even relevant to you — and, if it is, what your next step should be.

What changes on 1 July 2027
#

For individuals and trusts, from 1 July 2027 the 50% CGT discount is replaced by CPI indexation of the cost base (partners are taxed as individuals on their share). A separate 30% minimum tax (a floor, not a flat rate) then applies to Australian-resident individuals only — it reaches a trust or partnership gain only once that gain is attributed to an individual, and the market value of your property just before 1 July 2027 — that is, at the end of 30 June 2027 — becomes your new cost base — a one-off reset. Gains are then measured from that reset value, not from what you originally paid.

SMSFs and companies sit outside the new CGT regime for property acquired on or after 20 September 1985 — but pre-CGT property is caught whoever holds it, and foreign residents are not simply outside it. See below.

Are you affected? Four questions

Tick the ones that apply to you:

Tick what applies to see whether the 2027 reset is likely relevant to you.

If all four apply, the reset is likely relevant and the readiness checklist is your next step. If you’re unsure about any of them, that’s a good question for your accountant.

Where to go from here
#

  • All four applied? You’re likely affected — work through the CGT 2027 readiness checklist.
  • Property held through an SMSF? You’re outside the discount and indexation changes unless the property was acquired before 20 September 1985, in which case the 1 July 2027 reset still applies. SMSFs also have a separate annual valuation obligation — SMSF Property Valuation Ready.
  • Bought before 20 September 1985? The blanket pre-CGT exemption ends for gains after 1 July 2027, and those properties get a deemed cost base equal to market value on 1 July 2027 — dated evidence matters here. Confirm treatment with your accountant.
  • Want the mechanics? How the reset works, and the free apportioning method the Treasurer is setting as the alternative to a valuation (still a draft), are covered at CGT cost base explained.

What “ready” looks like
#

You’re CGT-ready when you know which of your properties are affected, your ownership records are together, you’ve chosen an evidence path with your accountant (a dated valuation or the Treasurer’s apportioning method), and 30 June 2027 is diarised. None of this requires rushing — a market value as at the end of 30 June 2027 can only be finalised once that date has passed, so preparing early is about being organised and defensible, not beating a clock.

Common questions
#

Am I affected by the 2027 CGT changes?
Likely yes if you hold CGT-liable Australian property as an individual, trust or partnership and expect to still own it on 1 July 2027. SMSFs and companies are outside it for property acquired on or after 20 September 1985 — pre-CGT property is caught whoever holds it, and foreign residents lose the 50% discount without gaining the replacement indexation. Confirm with your accountant.
What actually changes on 1 July 2027?
For individuals and trusts the 50% CGT discount is replaced by CPI indexation of the cost base. A separate 30% minimum tax (a floor, not a flat rate) applies to Australian-resident individuals only — a trust or partnership gain meets it once attributed to an individual, not at trustee level. Concessional treatment is also retained for new residential dwellings and affordable housing. and the market value at the end of 30 June 2027 — just before 1 July 2027 — becomes your new cost base. It is now law (Act No. 49 of 2026).
I hold property in an SMSF or company — am I affected?
For property acquired on or after 20 September 1985, SMSFs and companies keep their existing CGT settings and sit outside the discount, indexation and minimum-rate changes. But if the property was acquired **before 20 September 1985** the 1 July 2027 cost-base reset still applies — that rule is written by asset type, not by who holds it. Foreign and temporary residents are a separate case again: they remain liable on Australian property and lose the 50% discount without gaining the indexation that replaces it. Confirm your position with a registered tax professional. SMSFs do still have a separate annual valuation obligation — see SMSF Property Valuation Ready.
What about property bought before 1985?
The blanket pre-CGT exemption for assets acquired before 20 September 1985 ends for gains after 1 July 2027; those properties get a deemed cost base equal to market value at the end of 30 June 2027, just before the reset takes effect. Confirm treatment with your tax professional.
What does "ready" look like?
You know which properties are affected, your records are together, you've chosen an evidence path with your accountant, and 1 July 2027 is diarised. The readiness checklist walks through it.
Do I need to do anything before 1 July 2027?
You can prepare early, but a valuation as at the end of 30 June 2027 is only finalised from that date. Preparing now is about being organised and defensible, not rushing — see when to get your valuation.
