The 2026–27 Budget delivered the biggest property-tax rewrite in a generation, but the impact splits sharply across the market. Existing investors are grandfathered (7:30pm 12 May 2026 cut-off), new builds are protected, and the pain lands squarely on new entrants buying established stock. Here’s the short list before we get into the numbers.
▸ Federal government Bigger tax take, cleaner reform optics
▸ Property developers New builds keep NG — permanent edge
▸ High-yielding properties Cashflow-positive — works under any regime
▸ State governments The triple whammy — see below
▸ New property investors CGT discount gone, NG capped to new builds
▸ $1–2m+ low-yielding stock Holding-cost math breaks post-2027
▸ Discretionary trusts 30% flat rate from 1 July 2028
The triple whammy on state budgets
1. Volume down → revenue down. Double squeeze: grandfathered investors have no rational reason to sell after mid-2027 (listings dry up), and new-investor demand for established stock thins out at the same time. Stamp-duty take suffers on both sides of the ledger — a new headache for state treasuries that lean heavily on it.
2. FHOG redirected to new builds — $10k per FHB. States now subsidising every new-home first-home-buyer at $10,000 a pop, with the federal supply push tilting demand straight at that bracket.
3. H&L = stamp duty on land only. Buyers shifting to house-and-land packages pay duty on the dirt, not the building — a meaningful per-transaction hit even when volume holds up.
The four property-tax changes that matter
Negative gearing: limited to new builds only on residential property. Properties held at 7:30pm AEST 12 May 2026 are grandfathered . Investments supporting government and affordable housing programs are also exempt.
CGT: 50% discount for individuals, trusts and partnerships replaced with cost base indexation + a 30% minimum tax rate . Buyers of new homes can elect either the old 50% discount or the new rules at sale. Main residence and super exemptions untouched.
Trusts: discretionary trust distributions taxed at 30% flat, paid by the trustee . Fixed, special disability and charitable trusts are exempt. Note: starts one year later than the headline reforms — useful planning buffer.
Housing: $2b over four years for enabling infrastructure to support up to 65,000 new homes , with $500m ring-fenced for regional Australia. Government framing: 75,000 more first-home buyers into the market over the next decade.

📌 Two clocks just started. The grandfathering gate closed at 7:30pm 12 May 2026 — anyone holding investment property at that moment keeps the old rules forever. For new acquisitions: established stock can still be negative-geared through the 14-month transition (until 30 June 2027), but only new builds keep negative gearing long-term.
The Real Money — Tax Impact in Dollars
A grounded look at what the negative-gearing change costs — and doesn’t cost — for the typical Sydney investor.
$10k loss → $3,200 back · $20k loss → $6,400 back
Inside the 30% bracket ($45k–$135k) plus 2% Medicare, every dollar of negative-gearing deduction returns 32¢ as a refund. Linear up to $135k; above that the marginal rate jumps to 39%. That’s the benefit new investors lose on established stock purchases after 1 July 2027 — grandfathered owners keep it.
Scenario A · 5.2% gross yield — still works after the change
Old / grandfathered / new build: $3,200 refund. Net holding cost ~$4,300/yr ($83/wk). Post-2027 established purchase: Loss quarantined. Net holding cost ~$7,500/yr ($144/wk). Damage ~$3,200/yr — one rent review or a 0.5% rate cut wipes it out.
Scenario B · $2.5m Sydney House @ $1,000/wk — 2.1% gross yield, the model breaks
Old / grandfathered (investor on $200k): $50,000 refund. Net holding cost ~$53,500/yr ($1,030/wk). Post-2027 established purchase: No refund. Net holding cost ~$103,500/yr ($1,990/wk). Damage ~$50,000/yr — almost double. Rent would need to jump to ~$3,000/wk to break even cash. Established Sydney trophy stock becomes economically irrational for new investor entrants.
Yield is the new shield. Grandfathering is the new moat.
Yield-positive sub-$700k stock keeps working under any regime. Low-yield Sydney trophy houses only work for new buyers if they’re banking on serious capital growth — or if the property is a new build that retains negative gearing. The existing portfolio you already own? Tax can’t replicate it for new entrants. That’s an asset.
5-Year Sydney Forecast — Price, Rent, Yield
Our base case across four price tiers, blending ANZ’s published forecasts with the budget overlay.
Sydney medians, blended house & unit. Rent forecast assumes 5–8% pa near-term moderating to 3–4% as new-build supply lands from 2028. Yields normalise via rent inflation — a $1m mid-tier asset moves from ~3.5% gross today to ~4.2% by 2031 without price growth doing the heavy lifting.
Three Moves for the Next 14 Months
Where we’re focusing client conversations between now and 30 June 2027.
Hold
If you already own investment property, you’re grandfathered. Don’t sell something you’d want to replace — the tax treatment is permanent and can’t be recreated by new entrants. That’s a structural premium.
Pivot
Grandfathering closed at 7:30pm 12 May. For new acquisitions, the long-term play is house-and-land or off-the-plan — they keep negative gearing indefinitely. Established stock between now and 30 June 2027 still gets NG through the transition, but loses it on 1 July 2027.
Yield-Tilt
For any post-2027 purchase, yield does the work that negative gearing used to. Sub-$700k yield-positive stock and new builds (which keep NG indefinitely) are the two tilts to make. Off-the-plan demand should spike from 2027.
The Second-Order Effects
Four downstream shifts worth tracking over the next 12–18 months.
House prices ~3% lower long-run · 0.6ppt drag on FY26 growth
Post-budget RBA modelling puts the long-run impact at roughly 3% lower house prices than the counterfactual, with the transition slow — about 0.6ppt off annual price growth by year-end and just under 1ppt off growth over 2027 . The negative-gearing change alone is equivalent to a ~90–155bp lift in investor mortgage rates in immediate cash-flow terms, though the lifetime cost is softened by loss carry-forward. The CGT switch from 50% discount to indexation + 30% min doesn’t always raise the tax burden — outcome depends on the inflation-vs-price-growth relationship. Headline forecast revised to 3% dwelling price growth for the year to Dec 2026 (down from 5%) and unchanged at 3% for 2027. Rents see a notably smaller impact. Watch for sentiment-driven overshoot in the short term, where prices could ease faster than fundamentals warrant.
Investor freeze + tight vacancy → rents up 5–8% pa near-term
Sydney vacancy is already at 1.1% with rent growth running near 6%. New-investor demand for established stock will thin out from 2027, but supply-side construction takes 24–36 months to deliver. SQM’s earlier modelling on similar NG changes pointed to 8–15% rent growth over three years . Existing portfolio yields actually improve as rents catch up — a $1m mid-tier yield moves from 3.5% to roughly 4.2% by 2031 with no price growth needed.
FY28–FY29 restructuring wave — start the conversation now
Discretionary trusts will be taxed at a flat 30% from 1 July 2028 — one year later than the headline reforms. For families using a trust to stream rental income or capital gains to lower-bracket beneficiaries, the income-splitting advantage largely disappears. Fixed, special-disability and charitable trusts are exempt. With 14 months runway, this is a planning conversation, not a panic one — but the work should start in FY27.
House-and-land + off-the-plan get a permanent tax edge
New residential builds retain full negative-gearing access indefinitely. Combined with the $2b enabling-infrastructure package (supporting up to 65,000 new homes, $500m for regional) and an FHB push targeting 75,000 additional buyers over a decade, expect developer margins to widen, off-the-plan investor demand to spike from 2027, and growth-corridor house-and-land to outperform. APRA’s 6× DTI cap stays in the picture as the real handbrake on borrowing capacity.
