The Budget Just Rewrote the Rules on Property. Here's What Changes for You - Yesterday.

Last night, Treasurer Jim Chalmers delivered the biggest shake-up to property investment tax rules since 1999. If you own a home, hold an investment property, or have been waiting on the sidelines to buy, the landscape just shifted underneath you.

Here's what actually changed, what didn't, and what you need to do now.

Two headline measures. Both take effect from 1 July 2027.

1. Negative gearing is now restricted, not abolished

This is the detail the headlines are getting wrong. Negative gearing hasn't been wiped out. But who can use it, and how, has changed materially.

From July 2027:

• New builds: negative gearing is still fully available. Buy a brand-new property, and you can still offset losses against your wage income.
• Established properties purchased after Budget night: you can still deduct losses, but only against rental income, not wages. Unused losses carry forward to future years.
• Properties you already own: nothing changes. Your existing tax treatment is locked in.

If you're an investor holding existing stock, tonight's budget doesn't touch your position. If you're buying an established property after tonight, your cash flow calculations just changed.

2. The CGT 50% discount is being replaced

From 1 July 2027, the flat 50% Capital Gains Tax discount will be replaced by an inflation-indexed model. You'll only pay tax on your real gain above CPI growth. A minimum 30% tax rate on gains also applies.

One important carve-out: investors in new builds can choose to stay on the old 50% discount or switch to the new model, whichever is better for their situation.

For long-term holders in a high-inflation environment, the new model could be neutral or even better. For shorter holds, the maths needs to be rerun. Every exit strategy built before tonight is worth revisiting.

Budget night didn't arrive in a vacuum. Last week, the RBA raised the cash rate by 25 basis points to 4.35%, its third consecutive hike this year, fully unwinding last year's easing cycle.

Headline inflation sits at 4.6%. The RBA's own forecasts have the cash rate potentially reaching 4.70% by year's end, driven in large part by energy price pressures from the Middle East conflict. CBA economists expect rates to hold from here, but describe further hikes as possible depending on the data.

Translation: the cost of carrying property debt is at its highest in years, and relief isn't guaranteed.

If you're an owner-occupier: Tonight's changes don't directly affect you, but the rate environment does. If you haven't reviewed your mortgage rate recently, you may already be paying a premium for loyalty. That gap only widens as rates stay elevated.

If you're an existing investor: Your properties are grandfathered. Nothing changes on your current holdings. But your next purchase, whether established or new, will be on different terms. Model the cash flow before you move.

If you're a first-home buyer, the policy intent is to tilt the playing field in your favour. Restricting negative gearing on established stock is designed to reduce competition from investors at auctions. Whether that plays out in prices takes time, but the signal is clear.

1. Check your rate. Lenders will likely reprice in response to both the RBA decision and last night's announcements. Use Bheja.ai's Check tool to see where you stand in two minutes, no broker, no paperwork.
2. Remodel your investment cash flow. If you hold investment property or are considering a purchase, your after-tax position has shifted. Use the Save tool to see whether a lower rate offsets some of that change. The numbers are worth running.
3. Let the monitor work for you: Inflation remains elevated and the next RBA meeting is 16 June. Set your monitor now so you are first to know when a better deal opens up, not reading about it after the window closes.
