Negative Gearing Changes Australia

The 2026-27 Federal Budget announced negative-gearing changes for Australian property investors from 1 July 2027. The announcement matters for planning, but it has not changed the current-law calculators or spreadsheet on this site. (Budget 2026-27 - Tax reform)

This guide explains what the Budget announcement says about new builds, existing properties, and established housing bought after Budget night, then separates those points from what the live negative gearing calculator currently models.

Quick answer

The Budget announced that negative gearing would be limited to new builds from 1 July 2027. It also says existing arrangements remain unchanged for properties held before Budget night. For investors who buy established housing after Budget night, the Budget page says losses can be deducted against residential property income and carried forward, but cannot be deducted against other income like wages. (Budget 2026-27 - Tax reform)

The negative gearing calculator remains a current-law 2025-26 estimator. It estimates annual tax effect, weekly cash position, and after-tax holding cost using the rules currently built into the site. It does not decide whether a property is grandfathered, a new build, or an established-housing transition case.

What the Budget announced for negative gearing

That distinction is the main product boundary. The announcement can be explained in content, but a calculator mode should wait until enacted rules and transition details are ready to model.

What has not changed yet

Property Tax Tools has not added:

• a 2027 negative-gearing calculator mode;
• a Budget-night ownership-status input;
• a new-build classification input;
• an established-housing transition input;
• loss quarantining against residential property income;
• carried-forward property-loss logic;
• a future-rule spreadsheet branch.

Under the current settings covered by this site, rental income and rental deductions are part of the investor’s annual tax position. The ATO residential rental property material remains the source boundary for the current-law rental-property model used by the site. (ATO — Residential rental properties)

How property investors should use the current calculator

Use the current calculator for the part it can still estimate: the property’s current-year annual tax effect and weekly after-tax holding cost.

If you need reusable scenario tracking, the property investment spreadsheet can keep rent, deductions, depreciation, land tax, CGT, and cash-flow assumptions in one model. Treat it as a current-law model unless the product page explicitly says a future Budget mode has shipped.

Planning questions raised by the announcement

The Budget announcement raises practical questions that need enacted detail and professional advice:

1. Was the property held before Budget night?
2. Would a future purchase be treated as a new build or established housing?
3. If losses are carried forward, what income can they be used against later?
4. How would jointly owned property losses be treated across different owners?
5. How would trusts, companies, SMSFs, or other structures be treated?
6. Would a purchase delay, sale delay, or build-vs-established decision create other tax or finance consequences?
7. What happens if a property changes use, ownership, or construction status?

The current calculator can organise the numbers for the adviser conversation, but it cannot answer those legal transition questions.

Should investors buy only new builds?

The Budget announcement makes new-build status more important, but it does not make a new build automatically better. A property decision still depends on price, rent, vacancy risk, borrowing costs, land tax, strata costs, depreciation, repairs, expected growth, and personal cash-flow capacity.

A practical comparison is:

• current-law after-tax holding cost;
• expected rent and vacancy;
• land tax and strata/body corporate costs;
• depreciation assumptions;
• likely exit CGT;
• finance and settlement risk;
• which Budget assumptions are unresolved until enacted law is available.

Use the negative gearing calculator to estimate the current-year holding-cost side. Use the capital gains tax calculator or CGT changes guide for the sale-side boundary.
