What is a P46 form?

P46 is the reference given to the form ‘Employee without the form P45’. You will usually need to complete a P46 if you start a new job and your last P45 is not available.

The P46 tax form is important because it helps you pay the right amount of income tax. If you don’t have a P45, or fill in a P46, your employer will normally need to use an emergency tax code against your salary, meaning you can over pay tax.


To get in touch with the tax office about your P46 or P45 call HMRC.

The most common reasons why you will need a P46 tax form are:

  • You can’t provide your new employer with your last P45 form
  • You are starting your first ever job
  • You are starting a second job without leaving your current employment

Completing a P46 tax form is your responsibility. You should not assume your employer will fill in a P46 for you.


What information do I need to provide on form P46?

The P46 form needs you to state information like whether you make any student loan payments and received any Job Seekers Allowance. Certain details about your tax code are also requested, along with some basic personal information.


Where do I get a P46 tax form from?

If you don’t have a P45 your new employer should provide you with the P46 form to fill in. Once you have completed and signed the P46 your new employer will pass it on to the tax office.


Are you due a tax rebate?

If your finding out about a P46 it’s a good time to ask yourself – “Am I due a tax rebate?”
