Part 1A of the P45 form is sent to HMRC by the employer, while Part 1B, 2 and 3 are given to the employee. The employee is required to keep Parts 2 and 3 of the P45 for their records and give Part 1B to their new employer when they start a new job.


In other words, Form P45 is a statement or confirmation of the amount of tax you have paid on your pay to date during the tax year. It is usually given to you by your employer when you leave your job. Your next employer will use the information on the P45 employee form to register you with the new owner with HMRC.

  • Parts 2 and 3 - Are meant to give to your new employer or Jobcentre. who holds one and sends the other to HMRC.

Your former employer is responsible for releasing your P45, although there is no legal time limit within which it must be released. Instead, employers are instructed to provide it on the last working day or "without reasonable delay" if this is not possible (for example, if the departure date falls within an annual leave period).

Why is the P45 So Important?

The P45 form is important for both the employee and the employer. For the employee, the P45 form provides important information that is required when starting a new job. The new employer will use the information on the P45 form to ensure that the employee is paying the correct amount of tax and National Insurance contributions.


For the employer, the P45 form is important because it is used by HMRC to ensure that the correct amount of tax is being paid by the employee. The P45 form provides HMRC with information about the employee's earnings and tax payments during their employment, which is used to calculate the employee's tax liability.


Without your P45 form, your employer cannot guarantee that you will get the correct social security number. This means you may be paying more tax or being placed on an emergency tax number. Although this money can be recovered by contacting HMRC, no one deliberately wants more paperwork, especially when it can be avoided so easily.


The P45 also has a number of functions that are not directly related to starting a new job. You will need it to fill out a tax return if necessary, as well as to apply for benefits and tax refunds if you are unemployed. You may therefore need to read your P45 to make sure you don't pay too much tax when withdrawing money from a pension. There are a variety of reasons P45s are important for you and for your workers:


● You have to provide these to meet the legal requirements.

● They will ensure that your employees aren't paying too little or many taxes.

● This means that former employees do not need to obtain an unexpected tax code when they begin their new job. This could help them save a significant amount of money in the beginning when they are paid by their new boss.

● The Department for Work and Pensions (DWP) requires P45 in order to process future claims for benefits.

● After retirement, your previous employees must provide their P45 to the pension company to ensure that they're not paying excessive tax for any withdrawals that they make from their pension accounts.

● You require a P45 in order to get tax refunds.

● If the employee you fired has other work and is required to submit an income tax return, then they'll have to fill out their P45.

● It's the way you inform HMRC about a new employee.


What Happens if an Employer Does Not Provide a P45 Form?

Employers are required by law to provide a P45 form to employees who leave their job. If an employer fails to provide a P45 form, they may be subject to penalties and fines from HMRC. Additionally, the employee may experience delays in starting a new job if they do not have a P45 form to provide to their new employer.


How Long is a P45 Valid?

A P45 is only valid for the entire tax year in which it was issued, but that doesn't mean you should remove it right after. You must keep these for your records at least 22 months after the end of the relevant financial year. However, you may want to keep it longer as HMRC reserves the right to conduct tax investigations up to 20 years after that time.

Who Issues the P45?

Your employer automatically gives and generates a P45 through its salary system. By law, your employer must give you a P45 at the end of your job - you can ask for it if they don't give it to you.


What Happens If My P45 is Not Correct?

If you get your P45, ensure that you have the correct information. If you're concerned about your personal information, contact your HR department to correct the information. If you believe your tax code is incorrect it is best to get in touch with HMRC. If you're about to start an entirely brand-new position, you might be able to fill out the 'Starter Checklist instead.


Do I Need to Keep My P45 Form?

Yes, it is important that you keep your copy and provide your final P45 to your new employer. If you don't, your new employer will usually have to use an emergency tax identification number against your paycheck and ask you to fill out form P46. P45 is also important if all of your income and tax information has not been recorded by the tax authorities. Unfortunately, this situation can occur and delay the reimbursement of the taxes due. P45 allows HMRC to quickly update its tax information. If you have to pay tax, you will get it back as soon as possible


Do You Have a Retired P45?

Your employer issues a P45 when you leave your job to retire. To ensure that you have entered the correct tax number when withdrawing your pension, you must pass the details on to your pension institution.


How Long Does It Take to Get a P45?

The employer must issue you a P45 whenever you quit your job regardless of the reason. However, depending on your circumstances you may not receive your P45 on the same date you are leaving. However, it is recommended that you receive it soon after taxes and other deductions have been taken care of for your final pay period.


Do You Get a P45 When You're Spoiled?

Regardless of how your job ended, you should get a P45 whether you quit, go bankrupt, or go bankrupt. If you don't have another job to move to, you'll need to bring your P45 to Jobcentre Plus to apply for benefits.


What if I lost my P45?

If you've lost your P45, you can't get a new one. When you start a new job without a P45, your new employer may ask you to complete a "beginner's checklist," which includes your personal financial information. Details of this can be used to calculate your tax number, although you may be given an emergency tax number if HMRC does not have sufficient information about your income and tax liabilities.

What Should I Do If a New Employee Doesn't Have a P45?

If you find that you are recruiting a new non-P45 staff member, complete the new HMRC Retirement Checklist. If there is no P45, the checklist will help you gather all the information you need to set up an employee in your PAYE system, including items such as:


● Personal information

● Loan obligations (including student loans)

● citizen service number


This checklist can be filled out digitally or as a printable document. Employees only need to provide this information to their employer instead of submitting the form to HMRC.


What Else Do I Need To Do When Changing Jobs?

In addition to obtaining your P45, you'll have to do a few administrative tasks prior to you starting employment. The day you start work you'll be expected by your new employer to ask for these:


● Your bank details

● A valid proof of ID Most often, it is an official driving license or a passport

● Address Details

● Your National Insurance number - if you're not sure what it is, GOV.UK offers advice on how to find it


What About a P46?

The P46 form was issued to anyone who hadn't had a job before, or who didn't possess the P45. The P46 form has been no longer in use however and is now replaced by the starter Checklist form. The Starter Checklist includes questions about the other jobs or benefits you may have. It also helps your employer determine the correct tax code prior to the time your first paycheck is sent out. If you don't have these details, you could be placed on the emergency tax code.
