Why is my Pension Input zero?

There are two reasons that your Pension Input is zero, page 10 of your Benefit Statement Shows the calculation.

The calculation of your Pension Input makes an allowance for the increase in the Consumer Price Index (CPI), as the CPI allowance for the 2023/24 tax year was 10.1% this will mean for many members their Pension Input is zero.

If you ceased to contribute to the Fund before the start of the 2023/24 tax year then unless you pay Additional Voluntary Contributions, your Pension Input will be zero as the increases that apply to your pension do not count towards Pension Input.
