Which Method Costs You Less Tax?

From 1 July 2027, your profit gets split in two and each half is taxed differently. You can set the split with a certified valuation - or let the ATO's day-count formula set it for you. Put your numbers in and see both.

What we've assumed: no depreciation or capital works deductions, no LMI, and no loan set-up costs. Those all move the real number. For the most accurate setup, create an account at thepropertyaccountant.com.au.
