P45 Acknowledgement Letter (UK)

A P45 Acknowledgement Letter in the United Kingdom is a legally binding written instrument.

The P45 itself is a mandatory HMRC form that records the employee's cumulative pay and tax figures from the start of the tax year to the date of leaving. It contains the employee's name, National Insurance number, the employer's PAYE reference, the tax code in operation at the date of leaving, the total pay to date, and the total tax deducted to date. This information is essential for the employee's new employer to operate the correct tax code and avoid emergency taxation under PAYE.

While there is no legal requirement to issue a separate covering letter with the P45, doing so is good practice and helps to confirm that the employee understands the document they are receiving, particularly if they have never received a P45 before. Many employees are unfamiliar with the P45 system and may not know what to do with Parts 2 and 3, which can result in unnecessary over-taxation at a new employer.

The acknowledgement letter also serves as a formal record that the P45 was issued on a specific date, which protects the employer in any dispute about whether the P45 was provided promptly and in accordance with the regulatory requirement.

The legal framework governing the P45 Acknowledgement Letter (UK) in United Kingdom draws on several key statutes and regulatory bodies. Under UK law, the UK GDPR and Data Protection Act 2018 apply to personal data processed under this agreement. The Consumer Rights Act 2015, enforced by the Competition and Markets Authority (CMA), protects consumer rights. Section 43 of the Companies Act 2006 governs company names. The Employment Tribunal adjudicates employment disputes under the Employment Rights Act 1996. The High Court of Justice and County Court have jurisdiction for civil matters under the Senior Courts Act 1981. Parties executing a P45 Acknowledgement Letter (UK) in United Kingdom should confirm the document reflects current law, including any amendments enacted since the original drafting date. The Freedom of Information Act 2000 sets the foundational requirements.

A P45 acknowledgement letter should be issued to every employee who leaves employment in England and Wales, regardless of the reason for their departure. This includes employees who resign, are made redundant, are dismissed, retire, or whose fixed-term contract expires without renewal.

The P45 — and the accompanying acknowledgement letter — should be provided to the employee on or before their last day of employment, or as soon as practicable thereafter. Where the employee is on garden leave during a notice period, the P45 should still be prepared in advance and dated from the actual termination date, not from the date the notice was given.

The acknowledgement letter is particularly useful in the following situations: where the employee is starting a new job immediately and needs to give Part 3 to their new employer without delay; where the employee is claiming state benefits and needs to provide the P45 to Jobcentre Plus; where the termination has been acrimonious and the employer wishes to have a clear documentary record of when the P45 was issued; or where the employee is unfamiliar with the UK PAYE system (for example, if they are a non-UK national).

Employers should retain a copy of the acknowledgement letter on the employee's personnel file, together with a copy of the P45 (Part 1A), as evidence of compliance with Regulation 36 of the Income Tax (Pay As You Earn) Regulations 2003.

Parties in United Kingdom should prepare a P45 Acknowledgement Letter (UK) proactively rather than waiting for a dispute to arise. Courts interpret agreements based on the written terms rather than oral representations. Under UK law, the UK GDPR and Data Protection Act 2018 apply to personal data processed under this agreement. The Consumer Rights Act 2015, enforced by the Competition and Markets Authority (CMA), protects consumer rights. Section 43 of the Companies Act 2006 governs company names. The Employment Tribunal adjudicates employment disputes under the Employment Rights Act 1996. The High Court of Justice and County Court have jurisdiction for civil matters under the Senior Courts Act 1981. Where the transaction involves regulated activities, prior approval from the relevant authority may be required before execution.

A P45 acknowledgement letter for use in England and Wales should contain several key elements to be informative and useful to the departing employee.

First, the letter should confirm that the P45 has been prepared and issued in accordance with Regulation 36 of the Income Tax (Pay As You Earn) Regulations 2003. This confirms the employer's compliance and establishes the regulatory basis for the document.

Second, the letter should clearly state the employee's details as they appear on the P45: full name, National Insurance number, and date of leaving. This cross-referencing helps the employee to verify that the P45 is correctly prepared.

Third, the letter should state the employer's PAYE reference number. This is the reference the new employer will need when they contact HMRC to obtain a tax code for the employee, and which Jobcentre Plus will need if the employee is claiming benefits.

Fourth, the letter should summarise the key figures from the P45: the tax code in operation at the date of leaving, the total gross pay in the current tax year to the date of leaving, and the total income tax deducted in the current tax year. These figures allow the employee to check that the P45 is correct before handing it to a new employer.

Fifth, the letter should provide clear instructions on what the employee should do with Parts 2 and 3. It should explain that Part 2 should be retained by the employee and Part 3 given to the new employer or Jobcentre Plus as appropriate.

Finally, the letter should include contact details for HMRC if the employee has any queries about their tax position, and should confirm that the employer has sent Part 1 of the P45 directly to HMRC as required.
