What is a P45? Well, think of it as your employment record in a neat little packet. When you start working for a new employer, they will request your P45 from your previous job to get all the necessary details about your tax code and earnings. It’s essentially proof that you were employed and paid taxes during that period.

Once you leave a job, your employer will provide you with a P45. It contains four parts and looks something like this:

  • Part 1A: This is your basic information, which includes your name, address, date of birth and NI number (National Insurance Number). Keeping this safe is important as it could be used for identity theft.
  • Part 1B: This part outlines all your earnings from that employer. It also includes tax codes and deductions made throughout the period of employment.
  • Part 2 & 3: These parts are usually left blank since they are sent directly to HMRC (Her Majesty’s Revenue & Customs). They contain details regarding any taxes paid and national insurance contributions made during that period of employment.

How Does P45 Work?

When it comes to understanding how a P45 works, it’s important to grasp the basics. Essentially, a P45 is an official document that employers provide to employees when they leave their jobs. It serves as a record of your employment history and tax contributions during that period.

The process begins when you hand in your resignation or are terminated from your employment. Your employer will then generate a P45 for you, which contains crucial information such as your National Insurance number, tax code, and details about any pay received up until the date of leaving.

Once you receive your P45, it’s essential to keep it safe as it can have implications on future employment opportunities. When starting a new job with a different employer, you will need to provide them with this document so they can accurately calculate your taxes.

Furthermore, the information provided on the P45 is used by HM Revenue and Customs (HMRC) to ensure accurate tax deductions from your wages. This means that without a valid P45 when starting a new job, there may be delays in correctly deducting income tax and national insurance contributions from your salary.

Why is a P45 Important?

Why is a P45 Important?

A P45 is an essential document for employers and UK employees. It holds crucial information about your employment history, including details of your earnings and taxes paid. Here’s why having a P45 is important:

Tax purposes: Your P45 provides vital information to HM Revenue and Customs (HMRC) regarding your income tax contributions from previous employment. This ensures that you are taxed correctly in future jobs.

Starting a new job: When starting a new job, you will need to provide your employer with your P45 so they can calculate the correct amount of tax to deduct from your salary. Without it, you may end up paying more tax than necessary.

Claiming benefits: If you become unemployed or are eligible for certain state benefits, having a valid P45 allows the government agencies to determine the appropriate level of support you are entitled to receive.

Pension contributions: A complete record of past employment on your P45 helps ensure accurate pension calculations once you reach retirement age.

Resolving discrepancies: In case there are any discrepancies or errors in your pay or taxation, having a copy of your P45 can serve as evidence and help resolve these issues promptly.

Holding onto this document is important as it acts as proof of income earned and taxes paid during previous employment – supporting accurate taxation while ensuring access to various work-related benefits.

How to Get P45 in the UK?

Getting a P45 in the UK is a straightforward process that ensures your employment status is properly recorded. When you leave a job, obtaining your P45 from your previous employer is important as it contains vital information for future employers and tax purposes.

To get your P45, you need to inform your employer about leaving the job and provide them with all necessary details, such as your last working day. Your employer will then generate and issue the P45 document, which consists of several parts – Part 1A, Part 2, and Part 3.

Your employer must send part 1A to HM Revenue & Customs (HMRC). This part includes your earnings during this tax year until you leave. Parts 2 and 3 are given to you for future reference or if you start another job before the end of the tax year.

Keeping these documents safe is crucial as they contain vital information needed when completing forms for new employment or filing self-assessment tax returns. If you misplace or lose any part of the P45 form, don’t panic! You can contact HMRC directly for assistance in obtaining a replacement copy.

Remember that each time you start a new job, you must present parts two and three of your most recent P45 or complete a starter checklist provided by your new employer. Doing so ensures that accurate records regarding taxation and National Insurance contributions are maintained.

Who Issues a P45?

Who Issues a P45?

Who is responsible for issuing a P45? The responsibility lies with your employer. When you leave a job, it is their duty to provide you with this important document. Your employer will prepare the P45 and give it to you on your last day of work or shortly after. It contains crucial information about your employment history, including details such as your tax code and earnings up until the date of leaving.

The P45 consists of four parts: Part 1 should be sent to HM Revenue and Customs (HMRC), while Parts 2 and 3 are given to you – one for yourself and one for any future employers. Part 4 remains with the employer’s records.

It’s worth noting that if you have multiple jobs simultaneously or change jobs frequently, each employer should issue a separate P45 when your employment ends with them. This ensures that all necessary documentation is provided both to HMRC and yourself.

Do You Get a P45 When You Retire?

Retirement is an important milestone in one’s life. It marks the end of a long and successful career, but what about your P45? Do you still receive one when you retire? Let’s find out.

When you retire, your employment status changes. Instead of leaving one job for another, you are leaving the workforce altogether. Therefore, technically speaking, there is no need for an employer to issue a P45 when you retire.

However, that doesn’t mean the information contained in a P45 becomes irrelevant. The details found in this document can still be useful for future reference or any potential pension-related matters.

It’s worth noting that various pension providers may request certain employment details to calculate your retirement benefits accurately. In such cases, having access to your previous employment history through a P45 can streamline the process.

While retiring doesn’t result in automatically receiving a traditional P45 form from your employer, keeping personal records of all necessary documentation related to pensions and retirement planning is essential.

So remember, even though you don’t get handed a physical P45 upon retirement, like when changing jobs within the workforce, maintaining accurate records throughout your working years will prove invaluable during this transition phase into retirement.

How Long is a P45 Valid for?

How Long is a P45 Valid for?

How long is a P45 valid for? This is a question that many employees and employers often ask. Well, the validity of a P45 depends on various factors.

It’s important to note that there is no set expiration date for a P45. However, its usefulness does diminish over time. Typically, a P45 is considered valid for the current tax year in which it was issued.

In practical terms, this means that if you start a new job in April or later, your new employer will require an up-to-date P45 from your previous employment within the same tax year. Otherwise, they may need to use emergency tax codes until they receive the necessary information from HMRC.

On the other hand, if you have been unemployed for some time and are re-entering the workforce after several months or even years, your old P45 may no longer be relevant or accepted by your new employer.


The P45 is an important document that you should keep safe. It contains information about your income from the previous job, which can be used to calculate tax liability and other benefits. Knowing how to get a P45 ensures that you have this important document on hand and can make sure all of your taxes are paid correctly. Having a good understanding of what a P45 is and how to obtain one will give you peace of mind, knowing that all of your financial affairs are in order.

The main purpose of a P45 is to provide relevant information to HM Revenue and Customs (HMRC) about your earnings, tax deductions, and National Insurance contributions. This information helps HMRC calculate how much tax you owe or are owed at the end of the financial year.

When starting a new job, having a P45 can be helpful for both the employer and the employee. It provides important information about your previous employment, such as how much tax you have paid and your tax code. This allows your new employer to accurately calculate your income tax deductions.

What happens if I have no P45?

If you find yourself without a P45, it’s important to understand the implications and take appropriate steps. Without this document, your new employer won’t have access to crucial information about your previous employment and tax status. So what happens if you don’t have a P45?

In such cases, they may ask you to complete a Starter Checklist or another form that provides the necessary details.

However, not having a P45 might result in an emergency tax code being applied until HM Revenue and Customs (HMRC) sends your new employer the necessary information. This could mean paying more tax initially than you should be based on your circumstances.

You can request a copy of your P45 from HM Revenue and Customs (HMRC). However, it’s important to note that they do not issue duplicate copies of the original P45. Instead, they provide a statement known as a ‘P60 End of Year Certificate‘, which contains similar information.
