The employee pension contribution rate depends on the annual income of the employee. You can change the rate in PennyPerfect by selecting the Pensions tab on the Options screen.
The employer pension contribution rate can be changed on the Employer tab.
After changing a contribution rate any existing sessions which are to use the new rate need to be edited to force a recalculation of the contribution amount using the new rate. This can be done by editing the session and unchecking then rechecking the check box 'Employer Pension Contribution' and this will re-calculate the necessary figures.
More details about the NHS pension schemes can be found on the NHS pension websites.
