# How do I calculate irregular late payments to leavers?

When an employee is made a leaver on the payroll, **HMRC** will be notified when the **RTI** data is submitted each pay period. You need to give the employee a **P45** form for their records, which shows the total pay and tax in the employment tax year.

If an employee leaves and there is an irregular payment required to be paid, their **National Insurance Contribution** payment can be calculated on a weekly basis instead of on a monthly basis.

## To make a late payment to a leaver

1. Create a **Leavers Irregular Late Payment**: When selecting a leaver record and clicking the **Irregular Payment to Leaver** button, a confirmation message appears stating: **If you are making a late "Irregular" payment then NICs will be calculated on a weekly NIC earnings period. Please confirm if payment is "Irregular". Go to Cintra iQ:** Employment record > Tax & NI window > National Insurance tab > Irregular Payment To Leaver button.
2. Create a new **Leavers Irregular Late Payment** period: If an employee is leaving in the current period and you need to pay an irregular payment and apply a weekly **NIC** basis, navigate to the **Leavers Irregular** payment period(s) window and right-click: **New**. The period automatically appears in the window. **Go to Cintra iQ:** Employment record > Payroll Membership > Payroll Membership History.
