Australia's new CGT laws use a nine-step formula to split your gain. For many asset owners, it produces a worse outcome than a professional valuation. Find out where you stand in 60 seconds.
Two more figures and we can estimate how Treasury's formula splits your gain. Your best estimates are fine — this scan is directional, not a tax assessment.
Why your growth pattern matters. Treasury's formula assumes your asset grew at the same rate every single day. Assets that grew strongly before 2027 — long-held properties, established businesses — are often penalised by this assumption. The scan estimates whether that applies to you.
Indicative only. Based on current draft Treasury apportioning methodology (Treasury Laws Amendment (Tax Reform No.1) Bill 2026), which may change before it passes. Not tax advice.
Your scan used rough estimates. Enter your email and we'll send you a more detailed breakdown — including how connecting your accounting data (Xero, MYOB, QuickBooks) can sharpen the numbers and surface any documentation gaps before you talk to your accountant.

This scan is a starting point — not a substitute for professional advice. Your accountant can compare the Treasury formula against an actual market valuation and tell you which method produces the better outcome for your specific situation.

How it works
The scan applies Treasury's nine-step formula to your basic asset details and tells you whether the result warrants a closer look.
Type, purchase date, purchase price, and a rough current value. Takes about 60 seconds.
We apply Treasury's compound growth method to estimate how your total gain splits between pre- and post-July 2027.
If the formula appears to be working against you, your accountant can compare it to an actual valuation and advise accordingly.
Why this matters
From 1 July 2027, the 50% CGT discount is replaced by inflation indexation for future gains. To split the gain between the two periods, Treasury has proposed a nine-step formula based on constant compound daily growth.
The problem: real assets don't grow evenly. A property might sit flat for years and surge after rezoning. A business might accelerate after winning a contract. When that happens, Treasury's formula can push more of your gain into the higher-taxed post-2027 period than your actual growth would justify — a materially worse tax outcome.
A professional market valuation as at 30 June 2027 provides an alternative. For many owners it produces a substantially better outcome. This scan tells you whether the difference is worth investigating.
Assumes constant compound daily growth from acquisition to sale. Misses real-world value inflections — rezoning, renovations, contract wins. Available at no cost, but may overstate your post-2027 tax exposure.
Establishes the actual market value as at 30 June 2027, based on verified comparable data. Can be prepared retrospectively when you sell. Costs from a few hundred dollars — and often saves multiples of that in tax.
