Final Report: Detailed Analysis
A3. Wealth transfer taxes
A bequest tax would be a relatively efficient means of taxing savings. Decisions to save taken solely to fund consumption later in life would be unaffected. But decisions to save motivated by the desire to leave a bequest would be affected and this would impose some efficiency costs. In aggregate, though, bequest taxes are not likely to introduce large biases into donor behaviour. A bequest tax could increase labour supply and savings by recipients and prospective recipients, though the effects would be limited.
Such a tax could also be a progressive element of the tax and transfer system. Because the distribution of wealth in Australia is so uneven, most of the revenue available from a bequest tax could be raised from the top 10 per cent of households by wealth.
A tax on bequests would fit well with Australia's demographic circumstances over the coming decades. Over the next 20 years, the proportion of all household wealth held by older Australians is projected to increase substantially. Large asset accumulations will be passed on to a relatively small number of recipients. On the other hand, a bequest tax would be complex. There would be a need for anti-avoidance provisions, including a tax on gifts. There would, inevitably, be significant administration and compliance costs.
A tax on bequests should not be levied at very high rates. People should not be unduly deterred from saving to leave bequests. A substantial tax-free threshold combined with a low flat rate beyond that point would be an appropriate structure for a bequest tax. Bequests to spouses should be concessionally treated.
Another design issue is whether to tax the whole of the donor's estate or the inheritances received by individual recipients. There are arguments on either side, but on balance, they probably favour taxing each estate as a whole. A large number of other design issues would need to be considered. The more concessions and exemptions in the bequest tax, the greater its complexity and the greater the risk to efficiency and equity goals.
The Review has not sought to recommend the introduction of a bequest tax at this time, but believes that there should be full community discussion and consultation on the options.
