When the P60 figure differs from the March payslip, check whether there was a break in the employee’s service. The P60 reflects only the National Insurance (NI) contributions for the current period of employment.
For example, if the employee left in April and rejoined in May, the P60 will only display NI contributions from May to March.
In contrast, the payslip may display the full NI total for the entire tax year (April to March) if the following setting is enabled. To do this, follow the steps in portal.
Click Settings then under Company Parameters, click General Settings.
From the Company Code drop-down menu, select the relevant company code.
Click Next then enable the Multiple Periods of Employment toggle.
To save changes, click Save.
