2015/16 PENSION ANNUAL ALLOWANCE LAPSES ON 5 APRIL 2019
To utilize the 2015/16 unused relief any additional pension savings would need to be paid to the pension fund by 5 April 2019, otherwise the relief from 2015/16 will lapse.
Note however that for some taxpayers the method of calculating unused relief for 2015/16 is extremely complicated as the government changed the pension rules part way through the year on 8 July 2015. The amount of pension allowance will depend on the pension input period of your scheme and we can assist you in calculating the 2015/16 relief if you have not already had full relief already.
