Understanding the P6T Form in the UK

The P6T Form is a specific document used by HM Revenue and Customs (HMRC) within the UK's PAYE (Pay As You Earn) system. The PAYE system is how HMRC collects income tax and National Insurance Contributions directly from employment earnings. The P6T Form is categorized as a ‘PAYE Service’ generated notice of coding, which is issued to employers or pension providers. It details the tax code that should be applied to an individual's income, particularly in scenarios where there are multiple sources of income or adjustments needed to their tax code during the tax year.


Function of the P6T Form

The primary purpose of the P6T Form is to inform employers or pension providers about the tax code that needs to be used for an individual. This form is typically generated when there are updates to an individual's tax situation that necessitate adjustments in the tax code. These updates can be due to various reasons such as changes in personal allowance, additional sources of income, or receipt of taxable benefits. The form ensures that employers apply the correct tax code to the individual's earnings, which is critical for maintaining accurate tax records and deductions.


P6 vs. P6T: The Key Differences

While both forms are related to the tax codes used in the PAYE system, there are differences between the P6 and P6T Forms:


Issuance and Purpose

  • P6 Form: This is a PAYE coding notice that HMRC sends to employers. It contains details of changes to an employee's tax code, including previous pay and tax deducted within the tax year. Employers are supposed to update their payroll systems with the information from the P6 Form to ensure that the right amount of tax is deducted in future payments.

  • P6T Form: As mentioned earlier, this form is a 'PAYE Service' generated notice of coding issued for more specific circumstances. It is used when the system automatically generates a need to update an employer about changes in an employee's tax code.

Trigger for Issuance

  • P6 Form: It is usually issued when an individual has one source of income, and there is a change in their tax code due to various factors such as a new job, a change in benefits, or an update in personal allowance.

  • P6T Form: It is generally issued in response to more complex changes, such as when an individual has multiple jobs or pension sources, and their tax situation requires a more detailed review and update by HMRC.


Employer's Responsibility

Both forms require the employer to take action. However, the P6T may require more attention due to the complexity of the changes in tax codes it may present. Employers need to ensure they understand the instructions on both forms to apply the correct tax codes and avoid any issues with incorrect tax deductions.


The Importance of Accurate Processing

The accurate processing of both P6 and P6T Forms is crucial. Failure to update the employee's tax code in the payroll system promptly can result in incorrect tax deductions, which could either lead to an employee overpaying tax (and needing a refund from HMRC) or underpaying tax (which would need to be repaid to HMRC). This is why it is essential for employers to act swiftly upon receiving either form.



Both the P6 and P6T Forms are integral to the UK's tax system, ensuring that tax codes are updated and applied correctly to employees' earnings. Understanding the differences between these forms is key for employers to manage payroll effectively. It is the employers' responsibility to ensure that the tax codes provided by HMRC via these forms are implemented in their payroll systems without delay, guaranteeing compliance with tax legislation and the accurate deduction of taxes. The P6T Form, in particular, plays a significant role when there are complex changes to an individual's tax situation, requiring careful attention from the employer to handle these updates properly.
