Fourteen guides is more than anyone wants to browse. Each cluster below gathers the guides that apply to one situation and puts them in the order they actually matter — which date to establish first, which provision decides it, and which report you end up needing.

CGT fundamentals

CGT fundamentals: events, dates and cost base.

Capital gains tax on property comes down to three questions: what event happened, on what date, and what was the asset’s cost base. Get those three right and the calculation follows. Get the date wrong and nothing downstream can be salvaged.

Evidence & standards

Valuation evidence and standards for tax purposes.

The ATO does not test a valuation’s arithmetic. It tests whether the figure is supported — whether a qualified person inspected the property, researched genuine settled evidence, applied a recognised method and wrote down enough reasoning for a reviewer to follow it.

Exemptions & apportionment

CGT exemptions and apportionment on property.

Most of the money in a CGT position is decided by exemptions, not by the headline valuation. The main residence exemption, the six-year absence rule, pre-CGT status and the deceased estate rules each reduce or eliminate a gain — and each has a valuation requirement attached when it applies only partly.

Compliance calendars

SMSF and compliance valuations.

Some valuations are driven by a transaction. Others are driven by a date in the calendar, whether or not anything happened to the property. SMSF reporting is the main one, and from 1 July 2026 Division 296 adds a second.

Reference

Comparisons

Which report, and why not the cheaper one.

Most valuation mistakes are not errors of judgement about value. They are the wrong kind of report, commissioned for the wrong purpose, at the wrong date — and the cost of discovering that is always higher than the cost of the right report.
