New Gungahlin and Belconnen Developments Unlock Fresh Stamp Duty Savings for ACT Buyers in 2026

The ACT government's Home Buyer Concession Scheme has taken on new relevance this winter, as a string of residential developments across Gungahlin and Belconnen add hundreds of new dwellings to the market at price points that sit squarely within the scheme's eligibility thresholds. For first-home buyers and eligible upgraders willing to move fast, the savings are real and the timing is useful.

Stamp duty in the ACT is not cheap. On a median-priced Canberra house — currently sitting around $835,000 — a buyer without concessions faces a transfer duty bill of roughly $33,000 to $36,000. The Home Buyer Concession Scheme wipes that bill entirely for eligible buyers, provided the property falls under the income and property value caps. From July 1, 2026, the gross household income threshold sits at $186,650 for a single applicant, rising with each dependent, and the property cap has been lifted to $1 million for both new and established dwellings. That's a meaningful change from previous years, when the cap locked out many mid-market buyers.

Where the New Supply Is Landing

The timing aligns with a genuine lift in new stock. In Gungahlin, the final stages of the Kenny residential precinct off Horse Park Drive are now settling, with townhouses priced between $680,000 and $820,000 — well inside the scheme's ceiling. Further west, the Northbourne Corridor urban renewal continues to push new apartment supply toward the Dickson and Lyneham border, where two-bedroom units in newly completed blocks are listing between $590,000 and $720,000. Both corridors were specifically identified in the ACT Government's 2024 Housing Strategy as priority areas for density uplift, and developers have responded accordingly.

Belconnen's Kippax Fair precinct is also seeing action. A mixed-use development approved late in 2025 near Hardwick Crescent will deliver 140 apartments across two towers, with construction scheduled to begin by September 2026. Projects like this matter for the scheme because off-the-plan purchases can lock in concession eligibility at the time of contract, not settlement — a detail that catches many buyers off guard when prices shift during a long build.

The ACT Revenue Office, which administers the scheme, processed 3,412 concession applications in the 12 months to June 30, 2026 — up 11 percent on the previous year. Officials attribute part of that increase to the expanded income thresholds introduced in the 2025-26 ACT Budget. The scheme is not means-tested against assets, only income, which makes it particularly relevant for public servants in mid-career who have savings but are still earning within the cap.

How to Apply and What Buyers Need to Check

Applying is done through the ACT Revenue Office's online portal at the time of lodging the transfer duty return — typically within 90 days of settlement. Buyers must not have previously owned residential property in Australia, a condition the office verifies against data from other state revenue authorities. Couples where one partner has owned before are disqualified entirely, which remains one of the scheme's more frustrating hard edges.

Anyone targeting new developments should also check the property's completion certificate before signing. Several buyers in the Molonglo Valley suburb of Whitlam were caught out in 2024 when delays pushed their settlement past the financial year, altering the income assessment period. The ACT Revenue Office confirmed this year that it uses the income year in which the contract is signed, not settlement — a clarification worth confirming in writing with a solicitor before exchange.

With auction clearance rates holding near 65 percent and vacancy rates for rentals still below 1.5 percent across the inner north and inner south, the pressure on buyers isn't easing. New supply in the growth corridors offers a practical path for eligible buyers to enter the market with a five-figure saving in their pocket — but the window on any individual project can close quickly. The ACT Revenue Office's eligibility checker is available at revenue.act.gov.au, and the ACT Law Society maintains a list of solicitors experienced in off-the-plan transactions for buyers who want guidance before committing.
