From April 2016 onwards, the Annual Allowance will be tapered for 'adjusted incomes' over £150,000 by £1 for every £2. So, the Annual Allowance will range from £40,000 for 'adjusted incomes' of up to £150,000, to £10,000 at 'adjusted income' levels of £210,000 and above. This doesn’t apply to you if you have a 'threshold income' of £110,000 or lower. For definitions of the two different types of income please refer to the Annual Allowance Factsheet.
*The 2015/2016 tax year was split into two periods for Annual Allowance purposes – 6 April 2015 to 8 July 2015 and 9 July 2015 to 5 April 2016. The Annual Allowance for the first period was £80,000 and up to £40,000 could be carried forward to the second period, and this needed to be used before any carry forward from earlier periods.
If you exceed the Annual Allowance, you may be able to ‘carry forward’ unused allowance from the previous three tax years.
