What is a P45?

A P45 is an official tax document you get when you leave a job. It shows your total earnings and tax paid up to your leaving date.

It is important because you need it for:

Starting a new job
Updating tax records
Claiming refunds if overpaid tax
Sharing details with your new employer

Without it, your new employer may use emergency tax until your records are updated.

When Sainsbury’s sends your P45

Your P45 is not given on your last working day.

Usually:

It is processed after your final payroll is completed
It is issued within a few weeks after leaving
It may come after your final payslip is generated
It is either posted or made available digitally depending on system access

If payroll is busy or your leaving date is close to a pay cycle, it may take slightly longer.

How to get your P45 from Sainsbury’s

1. Check your last payslip or portal first

Sometimes P45 is available in your employee portal for a short time after leaving.

Steps:

Try logging into MySainsburys or MyHR
Check Payroll or Documents section
Download P45 if available

2. Check your email or postal address

Sainsbury’s may send your P45 by:

Post to your home address
Or sometimes via email (depending on setup)

Make sure your contact details were correct before leaving.

3. Contact HR or payroll team

If you cannot find it, the most reliable method is to contact HR.

You should provide:

Full name
Employee ID (if available)
Date of leaving
Store location

They can reissue or resend your P45.

Why your P45 may be delayed

Sometimes P45 is not sent immediately due to:

Final payroll still processing
System update after leaving employment
Incorrect address or missing contact details
High workload in payroll department
Delay in employment record closure

In most cases, it is issued automatically after payroll completion.
