The Independent carries an article today which flags up the disincentives facing thousands of households on low incomes. According to the piece, “A total of 60,000 households receiving income-related benefits or tax credits will face handing 90p of every extra pound they earn to the Treasury next year, twice this year’s total…. and the number of low-income households with a marginal tax rate of more than 60 per cent will grow by 85,000 to more than 1.9 million next year.”

The reason is the complex working of the tax credit and benefit system where working a few extra hours a week causes benefit recipients to lose means-tested (income related) benefits as well as having to pay more in income tax and national insurance contributions. Single mothers returning to work are thought to be especially at risk of the povert ytrap effect - currently, anyone working more than 16 hours a week loses their right to benefits.

This is an important issue - the effective tax rate paid by many thousands of people towards the lower end of the pay ladder can be twice that paid by the richest in society - raising questions not just about economic efficiency and incentives to work (key supply side issues) but basic fairness / equity.
