When hiring a new employee, employers must determine the appropriate tax code and starter declaration for their payroll software. Using incorrect tax codes can result in the new employee over or underpaying their taxes. To ensure the correct information is entered, employers need certain details from the new employee, most of which are usually provided on the employee's P45. It's important to remind new employees to bring their P45 on their first day.
If the employee does not have a P45, the required information can be gathered by asking them to complete HMRC’s online PAYE starter checklist. If they cannot use the online version, a paper version is also available. Employers must keep this information in their payroll records for the current tax year and the following three tax years. Once the information is collected, employers can use HMRC’s online tool to determine the employee’s tax code.
The starter checklist should be completed by new employees in the following cases:
- They have a student or postgraduate loan
- Their personal details differ from those on their P45
- They do not have a P45
- They have been sent to work temporarily in the UK by their overseas employer
Once the checklist is completed, the employee can submit it to their employer via email, post, or in person. There is no need to send the checklist to HMRC.
