George Osborne today confirmed the income tax allowance for 2015/16 will rise to £11,000, equivalent to £212 a week of tax-free earnings for all but the highest paid.The Treasury estimates this will lead to 29 million people being better off, including 570,000 who will see their income tax bill disappear completely. A basic-rate taxpayer will pay £905 less in 2016/17 than in 2010 as a result of the increased personal allowances.Legislation has also been created to ensure those on the minimum wage will not pay income tax on earnings up to 30 hours a week in future. Higher-rate taxpayersThe 40% higher rate tax threshold is also rising by £615 to £43,000 in April 2016. The higher-rate threshold is forecast to rise to £50,000 by 2020. Devo-taxScottish taxpayers may see their income tax rates change in April 2016, when the Scottish parliament is due to take control of its income tax. The UK government has announced intentions to allow the Welsh Assembly to set its own income tax rates without referendum, though an implementation date has not been set. Salary sacrifice schemes at riskThough no changes to salary sacrifice schemes have been announced, “the government remains concerned about the growth of salary sacrifice arrangements and is considering what action, if any, is necessary”, according to documents released today by the Treasury.
