What is a P45 and How to Get it?

A P45 is the statutory form a UK employer issues to an employee when their employment ends. It shows earnings, tax deducted, tax code, and National Insurance details for the current tax year up to the leaving date. The new employer uses the P45 to set up PAYE correctly, avoiding emergency tax and ensuring the employee pays the right amount of income tax through the rest of the tax year.

Key takeaways

  • A P45 is a UK statutory tax form that an employer must provide to every employee when their employment ends, summarising earnings and tax paid in the current tax year up to the leaving date.
  • The P45 is split into four parts: Part 1 is sent to HMRC, Part 1A is kept by the employee, and Parts 2 and 3 are given to the next employer for PAYE setup.
  • Employers must issue a P45 without unreasonable delay once employment ends, typically on or before the final payslip, and can no longer issue paper P45s from HMRC after April 2019 has been replaced by RTI.
  • The new employer uses a P45 to apply the correct tax code and cumulative pay and tax figures, which avoids the employee being placed on emergency tax for their first months.
  • Employees who lose or never receive a P45 can still start a new job using HMRC's Starter Checklist, with the new employer applying a tax code based on self-declared employment status.

What is a P45?

A P45 is a tax document that employers issue to employees when they leave a job. It includes important information about the employee's income and the taxes they've paid so far in the tax year. It also helps employees to claim tax refunds or apply for benefits more easily.

The form is divided into four parts: Part 1, Part 1A, Part 2, and Part 3. Each part serves a specific purpose and is handled by different parties.

Breakdown of the P45 Form:

  • Part 1: Sent to HMRC by the employer.
  • Part 1A: Given to the employee for their records.
  • Part 2 and Part 3: Given to the employee to pass on to their new employer or to the Job centre Plus if they are not moving directly into a new job.

Key Information Included in a P45

A P45 form includes the following information:

  • Employee’s name, address and National Insurance number
  • Start and end date of employment
  • Payroll number
  • Tax code
  • Taxable pay
  • Taxable benefits
  • Tax paid
  • Total tax paid
  • Tax year
  • Taxable pay for the tax year
  • Total tax paid for the tax year
  • Total tax deducted from the employee’s pay

When is a P45 issued?

A P45 is issued to an employee when they leave their job. It is important that the employer issues the P45 to the employee as soon as possible after they leave their job. The employee should then keep the P45 in a safe place as they may need to refer to it in the future. When starting a new job, the employee will need to provide the P45 to their new employer. This is to ensure that the correct amount of tax is paid to HMRC.

Why P45 Important?

The P45 is important for several reasons:

  • Tax purposes: It helps your new employer apply the correct tax code, so you don't overpay or underpay taxes.
  • New employment: When you start a new job, your new employer uses the P45 to ensure they deduct the right amount of tax from your salary.
  • Claiming benefits: If you are not immediately starting a new job, you may need to provide your P45 to the Jobcentre Plus to claim unemployment benefits.
  • Tax refunds: If you have overpaid tax, your P45 can help you claim a refund from HMRC.

What happens if an employee does not receive a P45? If an employee does not receive a P45 from their previous employer, they should contact HMRC. HMRC will then contact the previous employer to request the P45. If the employer is unable to provide the P45, HMRC will issue an emergency tax code to the employee. This code will be used by the new employer to calculate the correct amount of tax to be paid.

Frequently asked questions

What does a P45 form contain?

A P45 shows the employee's tax code, leaving date, gross pay, and tax deducted for the current tax year up to the date employment ended. It also includes the employer's PAYE reference, the employee's National Insurance number, and the total amount paid and taxed in the job. Student loan plan type, a week 1 or month 1 indicator if used, and cumulative figures for any previous employments already reflected in the current year are also reported.

When should I receive a P45?

A UK employer must provide a P45 without unreasonable delay once an employee's employment ends. In practice this usually means on or shortly after the final payday, alongside or just after the last payslip. HMRC expects the P45 to be issued automatically — employees should not have to request it. If a P45 has not arrived within a week or two of the final payment, contact the former employer's payroll department directly.

What are the four parts of a P45?

A P45 is split into four parts. Part 1 is submitted to HMRC by the employer when employment ends, which updates the employee's tax records. Part 1A is given to the employee for their own records. Parts 2 and 3 are both handed to the new employer: Part 2 is kept for payroll reference, and Part 3 is sent to HMRC so the new employment is set up correctly under PAYE.

What should I do if I have lost my P45 or never got one?

If a P45 is lost or was never issued, a new employer should use HMRC's Starter Checklist instead. The employee answers a short questionnaire about their employment status in the current tax year, and the new employer uses the result to apply an appropriate tax code, usually on a week 1 or month 1 basis until HMRC issues a cumulative code. This avoids an emergency tax code hitting the first payslip.

Why is the P45 important when starting a new job?

A P45 tells the new employer what tax code to use and what pay and tax have already been applied in the current tax year. Without it, the employer has to use an emergency tax code or the Starter Checklist, which can lead to the employee overpaying tax for one or two pay periods until HMRC issues the correct cumulative code. Handing the P45 over promptly usually means tax is correct from day one.

Do I get a P45 if I am self-employed or a director?

Self-employed people do not receive a P45 because they are not employees under PAYE. Company directors on payroll do receive a P45 when their directorship ends, assuming they were paid a salary processed through payroll. If the directorship continues but the director stops taking a salary, no P45 is issued; the employment is simply paused on the payroll record until the next salary payment or until the directorship is formally ended.

Is a P45 the same as a P60?

No. A P45 is issued when employment ends and covers pay and tax for part of the tax year. A P60 is issued to every employee who remains on payroll at the tax year end of 5 April, summarising total pay and tax for the whole year. Employees who change jobs during a tax year therefore receive a P45 from the old employer and a P60 from the new employer for the complete tax year.
