If you earn over £150,000, the amount you can invest is subject to ‘adjusted income’. How much you can invest is tapered, so for every £2 above £150,000 the annual allowance is reduced by £1.
This means if you earn more than £210,000 a year (£60,000 over the threshold), the most you can pay into your SIPP each year then reduces by £30,000 to just £10,000.
The right to ‘carry forward’ any unused allowance can be useful for higher earners affected by the tapered annual allowance introduced in April 2016. With carry forward you could contribute up to three years and still benefit from the government’s tax relief.
