What is a P45?

If you’ve ever left a job, you will have received a P45. This is an official form issued by your employer, containing all the details of your salary and how much tax you’ve paid so far in the tax year.

In this guide, we’ll give you the lowdown on everything you need to know about the P45 form. We’ll cover the information it includes, how to understand the different parts of the form and the circumstances in which you can expect to receive a P45. And crucially, why the P45 is important.

We’ll also take a quick look at one of the most cost-effective ways to get paid in multiple currencies - the Wise multi-currency account. If you’re thinking about your P45 because you’re changing jobs or perhaps stepping out as a freelancer, this could come in really handy.

But more on this later. Let’s concentrate on the P45 for now.

What information is on a P45?

A P45 form will outline all the details of your pay and tax, up until the date you left your job. Here’s what you can expect to see:

• Your employer details, including PAYE reference
• Your details, including your National Insurance number
• Your tax code
• The date you left your job
• Your total pay in that job to date
• The total tax you paid in that job to date.

Understanding the parts of a P45

The P45 form isn’t just one page - it’s actually made up of four different parts.

Part 1 is sent to HMRC, while Part 1A is your copy as the employee. You should keep this somewhere safe for your records. We’ll look at why you might need your P45 in just a moment.

Part 2 and 3 are to be given to your new employer, when you start a new job.

When will I receive a P45?

A P45 is issued whenever you leave a job, no matter what the circumstances are. This means you’ll get one if you resign or are made redundant, or if your employment is terminated. You should also get a P45 when you retire.

What to do if you lose your P45

Unfortunately, you can’t get a replacement if you lose your P45. Instead, you’ll need to fill out a Starter Checklist when starting a new job. This should cover all the basics that HMRC will need to calculate your tax code. However, if there isn’t enough information available, there’s a chance you’ll be put on an emergency tax code.

What’s the difference between a P45 and a P46 or P60?

It’s easy to mix up the P45 form with other similar-looking forms, the P46 and P60. They contain some of the same information, but they have different purposes. We’ve already covered the P45, so here’s a quick guide to the other two:

A P46 is for people who’ve never worked before, or who don’t have a P45. It’s no longer in use, as it’s been replaced by the Starter Checklist form. This helps to gather the essential information about new workers, so they don’t end up on an emergency tax code.

A P60 is an annual summary of the tax you’ve paid on your salary within the tax year. It contains much of the same information as the P45, but for a whole tax year (rather than up to the point where you left your job). The P60 is issued every April, after the end of the tax year, by your employer.
