How stamp duty is calculated in ACT

The ACT is in the middle of a long-term phase-out of stamp duty, replacing it gradually with a broad-based land tax. Rates are still significant — 5.25% applies between $500k and $750k, jumping to 7% above that — but expected to fall further over the next decade.

ACT does not currently offer a stamp duty concession or exemption for first home buyers. The First Home Owner Grant may still apply for new builds — check the ACT Revenue Office website.

The figures above use the ACT ACT Revenue Office schedule. Rates are reviewed periodically — always confirm the latest figures with the official state revenue office before making an offer.
