Swapping stamp duty for land tax is not as novel as it sounds, with the ACT government already implementing such a plan and the NSW government planning to do the same via a novel opt-in arrangement. The ACT already has Australia’s most efficient tax base, with every dollar of revenue raised costing the economy just 21.9 cents. In contrast, NSW has the least efficient system, with every dollar of revenue raised costing the economy 29.7 cents. Part of this discrepancy is due to the replacement of stamp duty with broad-based property taxes.
Rather than being set in stone, state tax measures need to change over time to meet the economic circumstances of the times. Taxes on transactions, including stamp duties on real estate, are recognised as particularly inefficient. In fact, stamp duty has become less and less efficient over the past five years, with low interest rates and booming property prices in Sydney and Melbourne inflating stamp duties and giving them a growing share of the tax base. The typical stamp duty bill is now above $40,000 in Sydney and Melbourne, with questions once again being asked about alternatives.
Not only is stamp duty inefficient, but changes would also make housing more affordable and fair for many Australians. Swapping stamp duty for land tax is likely to reduce the average purchase price for homes, along with increasing the total number of transactions and improving the rate of home ownership. Young adults, renters, and anyone struggling to save for a deposit would be likely to benefit. While current homeowners would generally be worse off, this change could increase house values for sellers and landlords. In addition, some families pay more tax than others simply because they move house more often, which is fundamentally unfair. ;
In the ACT, there has been a gradual transition away from stamp duty for all purchases, with this tax completely waived for many residential land and off-the-plan apartment purchases. NSW is making a similar move, with home buyers given a choice to pay either stamp duty and land tax or a new annual property tax. According to calculations by the Conversation, Australians would be up to $17 billion a year better off if the entire country made the same decision. Instead of inefficient stamp duty, an annual flat tax of $5-$7 for every $1,000 of unimproved land value would be more than enough to void property stamp duties. As the ACT and NSW models continue to see success, nationwide adoption of a new system looks more likely each year. ;
