Understanding property CGT

What is taxed?

Capital gains tax is generally based on the gain, not the full sale value.

Why does ownership matter?

An individual estimate is not always the same as a company estimate. Companies can have different tax treatment.

What is cost base?

Cost base may include acquisition cost, capital improvements, and eligible sale-related costs, subject to documentation and applicable rules.

Formula used

  1. Cost Base = Original Cost + Improvements + Eligible Selling Costs
  2. Capital Gain = Sale / Transfer Value − Cost Base
  3. Estimated CGT = Capital Gain × Selected Tax Rate
  4. Balance = Estimated CGT − Tax Already Paid
  5. Rough After-Tax Proceeds = Sale Value − Selling Costs − Estimated CGT
