Turn New Tax Rules Into Better Property Decisions This Week

Using a CPA mortgage broker to model after‑tax outcomes means stress‑testing your loans and properties with both tax law and lender rules in mind, not just headline rates. It lets you compare options like “upgrade home”, “buy an investment”, or “debt recycle” on a single, after‑tax cashflow and wealth‑building scoreboard under the new negative gearing and CGT rules.

Here’s how to get decision‑grade numbers in the next week.

After-tax property modelling compares scenarios on one clear cashflow and net-worth view.

What’s changed: why after‑tax modelling suddenly matters more

Two big rule shifts mean rough spreadsheets are no longer enough:

1. Negative gearing reforms (Federal Budget 2026)

   • New established properties bought after 12 May 2026 generally won’t get full rental loss offsets.
   • New builds and some institutional/large‑scale structures are carved out, but with strict definitions.

2. CGT reform bill for 2027

   • The classic 50% CGT discount is being replaced with indexation plus a 30% minimum tax on most capital gains.
   • More complex categories of gains and much tighter record‑keeping.

Add APRA’s 3% serviceability buffer, and it’s no longer enough to ask “Can I get approved?” You need to know: “After tax, does this still build wealth and keep my cashflow safe?”

What a CPA mortgage broker actually does differently

A normal broker models pre‑tax repayments and basic rent. A CPA‑qualified mortgage broker who also works as a tax adviser can layer in:

• True after‑tax cashflow

  • Income tax on wages, dividends and trust distributions.
  • Reduced or quarantined negative gearing benefits for established properties.
  • How depreciation and new‑build concessions change the picture.

• Entity and structure choices

  • Personal vs company vs family trust vs SMSF.
  • How different owners change both borrowing power and CGT later.

• Loan structure impacts

  • Splitting home, investment and business debt so deductible and non‑deductible interest are cleanly separated (see also /insights/balancing-business-expansion-and-investment-property-purchases).
  • Using offsets on non‑deductible splits to keep future deductibility intact.

• Risk and buffer analysis

  • Stress tests at +2–3% on rates and lower business drawings for self‑employed clients.
  • Mapping you against Roy Morgan-style ‘At Risk’ and ‘Extremely At Risk’ bands using after‑tax income.
