Today's newspapers are full of predictable criticism for George Osborne's only Budget surprise - removing the higher tax allowances enjoyed by people aged 65 and over. The Chancellor has bungled this announcement, slipping it into the budget statement as a 'simplification' when it is clearly a tax rise of around £200 a year for millions of pensioners. But is it really such as a bad idea?
Older people have been relatively protected from the spending cuts imposed by the coalition. The young have taken the brunt of the pain, seeing an end to their educational maintenance allowances and the scrapping of the Future Jobs Fund. Youth unemployment has topped 1 million, the highest since records began. Working families have already seen their budgets stretched as tax credits for low earners are frozen and support for childcare reduced. Many older people enjoyed windfall gains from the house price boom that has priced many younger families out of the market.
This is not a crude argument that pits young against old. But as the population continues to age, putting extra pressure on public services, parties on all sides will have to make tough choices about tax and spend. Asking older people to contribute to tackling the deficit and shoring up the country's tax base in the long-term is not unreasonable. This is particularly true if we bear in mind that only a fifth of pensioners are poor - retirement no longer means the life of poverty that it might have a hundred years ago when the higher allowances were introduced.
"Granny tax": which pensioners lose out?
Removing the age-related allowances also makes sense because, on average, it takes much more from better off pensioners. It is true that the wealthiest fifth of pensioners do not lose much. They are not entitled to the higher allowances, which are reduced as income rises above £24,000. But IPPR analysis shows that the poorest fifth also lose very little. Most have incomes below the allowance so will not be affected by the freeze. The chart above shows that the biggest losses will be felt by the second richest fifth of pensioner households (those in the 4th income quintile). They are more likely to have two pensioners with incomes above the allowance but below the income limit.
Osborne's pleas of simplification have not played well, but he is right that age-related allowances add huge complexity to the tax system. This is important because it means that many pensioners do not even claim the higher allowance they are entitled to. An official report  in 2009 estimated that 3.2 million older people failed to claim the extra allowance they were entitled to, which is over half of all older taxpayers. There are simpler and better targeted ways of supporting pensioners struggling on low incomes, that do not rely on people claiming complex allowances.
