P6 Form

Q: What is a P6 form and when is it used?

A P6 form is an official notification from HMRC sent to employers to inform them of a change or update in an employee’s tax code. It is used after events such as starting a new job, submitting a Self Assessment, or a change in personal allowances. Timely processing of the P6 form helps ensure that payroll deductions are accurate and up to date.

Q: How do employers process P6 forms electronically?

Employers often receive P6 forms through their payroll software, which can automatically update the employee's record with the new tax code. Processing the form involves entering the revised code into the system before the next payroll run and ensuring the tax deducted aligns with HMRC’s instructions. This helps maintain compliance and reduces manual errors.

Q: Can receiving a P6 form affect an employee’s take-home pay?

Yes. A P6 form can result in a higher or lower tax deduction depending on whether the updated tax code increases or decreases the employee's tax-free allowance. For example, changing from an emergency code to a standard code typically increases take-home pay by ensuring correct tax calculation.

Q: How do you calculate tax after a P6 form updates a tax code?

After receiving a P6 form with a new tax code, employers use the annual tax-free allowance from the code to calculate taxable income. For instance, with code 1257L and an annual salary of £24,000, tax would be owed on £11,430 at the basic rate. Payroll software typically automates these calculations, but employers must verify accuracy with the updated code.

Q: What should employees do if they suspect their tax code is incorrect despite a recent P6 form?

Employees who believe their tax code is still wrong after a P6 form update should contact HMRC directly for clarification. Sometimes additional information or corrections may be needed to adjust the code. Keeping HMRC informed ensures taxation remains accurate.

Finance Dictionary >P6 Form

The P6 form is an official notification from HM Revenue and Customs (HMRC) providing new or revised tax code information to employers. This form helps ensure that employees are taxed at the correct rate, reducing payroll errors and preventing under- or overpayment of taxes. Given the pivotal role of accurate Pay as you earn (PAYE) processing in the UK employment landscape, employers must understand the function and handling of P6 forms. A notable point is that receiving a P6 often signals important changes—such as the start of new employment or updated employee tax information—that impact payroll calculations and compliance.

What is a P6 Form?

A P6 form is a tax code notification sent to employers by HMRC when there is an update or correction in an employee’s tax information. This might happen if an employee starts a new job, submits a Self Assessment return, or notifies HMRC about a change in benefits or allowances. The P6 details the employee’s new tax code and, if necessary, adjustments to their pay for tax purposes.

For example, if an employee named Alex starts a new job and submits their details to HMRC, but their initial tax code was an emergency code, HMRC may send a P6 to the employer with a revised code (such as 1257L), clarifying how future wages should be processed and taxed. This form ensures Alex pays the right amount of tax going forward, adjusted for any allowances or previous employment income.

When and Why are P6 Forms Issued?

P6 forms are issued whenever HMRC determines that an employee’s tax code needs to be updated after reviewing new information. Common triggers include the submission of a P45 by a new employee, the completion of a Self Assessment tax return, or changes in personal circumstances that affect tax allowances. Properly processing P6 forms is vital for employers, as incorrect tax codes could lead to complex rectifications, employee dissatisfaction, and non-compliance with PAYE regulations.

How Do Employers Process a P6 Form?

Upon receiving a P6 form, either electronically or on paper, employers update the affected employee's payroll record with the new tax code. Most modern payroll software is compatible with electronic notifications, streamlining the process. For example, suppose an employer receives a P6 for an employee changing from a 1160L to a 1257L tax code. The payroll officer needs to update the tax coding in their system before running the actual payroll, ensuring PAYE deductions reflect the latest instruction from HMRC.

Calculating tax using a new code involves multiplying the employee’s tax allowance by the proportion of the year worked and applying the revised code. In April, for the 2024/25 tax year, a code of 1257L allows earnings up to £12,570 before income tax is due. If this change occurs partway through the year, employers apply the adjustment using the payroll software, which ensures only the correct tax is deducted on future salaries.

Practical Example: Tax Calculation After Receiving a P6 Form

Suppose an employee’s tax code was previously BR (meaning all income is taxed at the basic rate, with no allowance), but a new P6 form provides them with tax code 1257L. The employer then needs to update payroll and re-calculate income tax for the upcoming period.

If the employee is paid £2,000 per month:

Annual allowance = £12,570 (from the 1257L code).
Taxable pay per year = £24,000.
Tax-free allowance used: £12,570.
Taxable income = £24,000 - £12,570 = £11,430.
Tax due (at current basic rate 20%) = £11,430 x 0.20 = £2,286 per annum.
Monthly tax deduction = £2,286 ÷ 12 ≈ £190.50.

This calculation illustrates how the P6 form ensures the employee is taxed only on income exceeding the personal allowance, correcting overpayments or avoiding underpayments from previous errors or emergency codes.

Pros and Cons of the P6 Form in Payroll Management

An advantage of the P6 form is its role in reducing payroll errors and keeping employees’ tax payments accurate and up to date. This not only helps employees avoid unexpected tax bills but also simplifies year-end payroll processing for employers. The P6 form also allows quick, secure electronic updates via Real Time Information (RTI) submissions, supporting compliance with HMRC rules and minimising manual intervention.

However, the system relies on prompt data from employees and HMRC. Delays in issuing or processing P6 notifications can momentarily lead to incorrect deductions, which may frustrate affected employees. Complexity arises when an employee has multiple jobs or unclear information, potentially causing confusion or necessitating subsequent corrections. While most payroll software is compatible with P6 updates, employers must remain vigilant for system discrepancies or manual errors.

Historical Context and Changes to the P6 Form

Historically, tax codes and their updates were communicated on paper, increasing the risk of lost forms and delays. Since the introduction of electronic communications through HMRC’s online PAYE services, the P6 notification process has become much more streamlined and reliable. The integration with RTI and automated payroll systems has greatly reduced the administrative burden for both employers and HMRC.

Key Features and Best Practices for Employers

Employers should always process P6 forms as soon as they are received, updating their payroll records before the next scheduled pay run. Secure storage of both paper and electronic records is important for audit purposes. If a P6 is not actioned promptly, employees could be over- or under-taxed, which may require complex repayment arrangements. Employers should regularly check for P6 messages through their payroll software or HMRC portals and ensure their payroll staff are trained to recognise and implement these updates efficiently.

Staying compliant with HMRC instructions and processing P6 forms accurately not only ensures staff are paid correctly but also contributes to the smooth running of business finances.
