What is a P45?

We break down what you need to know about a P45 form and what it entitles you to.

You get a P45 from your employer when you stop working for them. It's will show a record of your pay with them to date and the tax that's been deducted from it so far in the tax year. It shows:

  • your tax code and PAYE (Pay As You Earn) reference number
  • your National Insurance number
  • your leaving date
  • your earnings in the tax year
  • how much Income Tax was deducted from your earnings

It's good to know that a P45 has four parts - Part 1, Part 1A, Part 2 and Part 3. Your employer now electronically sends Part 1 details to HMRC and will give you the other three to you. When you start your new job or start to claim Jobseeker's Allowance, you give Part 2 and Part 3 to your new employer or the Jobcentre. You keep the remaining one - Part 1A - for your own records.

Your employer should automatically give you a P45 when you stop working for them. If not, ask for it - you're entitled to it by law and they should post the three parts meant for you as soon as possible.
