Weekly Payroll - Paid in Arrears

An employee starts work on Monday 11 January and is paid a week in arrears. He works 35 hours Monday 11/01 to Friday 15/01. He gets paid on Friday 22/01.

Which date is relevant in terms of receiving a PRSI credit, w/e 15/01 (the week he actually worked) or w/e 22/01 (the week he actually got paid)?

1 for w/e 15/1. On termination his arrears week and the credit catches up.

Thanks for the quick reply.

Does this mean that the employee should be processed on payroll run w/e 15/01 despite being paid one week later?
