What Is P9 Tax Code Notice 2023?


Understanding the P9 Tax Code Notice in the UK for 2023

The P9 tax code notice is a crucial document in the United Kingdom's tax system, especially for employers. It serves as a guide for employers to understand which tax codes need to be updated at the start of the financial year. With the tax year 2023 in focus, there have been some updates that both employers and employees need to be aware of. This article aims to provide a comprehensive understanding of what a P9 tax code notice is, its significance, and the updates for the year 2023.


What Is P9 Tax Code Notice 2023


What is a P9 Tax Code Notice?

A P9 tax code notice is a document issued by HM Revenue and Customs (HMRC) to employers. It outlines which tax codes need to be changed and how to go about making these changes. The notice is particularly important at the start of a new tax year, which begins on April 6th. The P9 notice helps employers adjust the tax codes of their employees in line with any changes in the law or personal circumstances that might affect the amount of tax an employee needs to pay.


Importance of P9 Tax Code Notice

The P9 tax code notice is essential for the smooth functioning of the Pay As You Earn (PAYE) system in the UK. PAYE is the system that employers use to deduct income tax and National Insurance contributions from employees' wages. The P9 notice ensures that the correct amount of tax is being deducted, thereby minimizing the chances of underpayments or overpayments.


Updates for 2023

For the tax year starting April 6, 2023, the P9X guidance has been updated. This guidance explains which tax codes employers must change and how to change them for the new tax year. The document is available in PDF and ODT formats and was last updated on February 17, 2023. Employers should pay close attention to these updates to ensure compliance with tax laws.


How to Access the P9 Tax Code Notice

Employers can access the P9 tax code notice online through the HMRC website. It is also sent by post and can be viewed online if you use HMRC’s PAYE Online for employers service. Employers using payroll software may receive this electronically.



Understanding the P9 tax code notice is crucial for employers in the UK. It serves as a guide for updating employee tax codes, ensuring that the correct amount of tax is deducted under the PAYE system. With the 2023 updates, it is essential for employers to review the new guidelines to maintain compliance with the tax laws.



Decoding the Intricacies of Tax Codes


Different Types of Tax Codes

Tax codes in the UK are usually a combination of numbers and letters, such as 1257L or K396. These codes are used to calculate the amount of tax to be deducted from an employee's pay. The numbers generally represent the tax-free income an employee is entitled to, while the letter indicates certain conditions that may apply. For instance, the letter 'L' signifies that the employee is entitled to the standard tax-free personal allowance.


How Tax Codes Work

The tax code serves as a guideline for employers to know how much tax to deduct from an employee's salary. Most people in the UK are entitled to a personal allowance, which for the tax year 2023/24 is £12,570. This is the amount an individual can earn without having to pay any tax. The tax code is adjusted based on this personal allowance and is allocated evenly throughout the year under the PAYE system.


Cumulative Tax Codes

In most cases, PAYE is calculated on a cumulative basis over a tax year. This means that if an employee starts work in the middle of the tax year, they will be allowed a proportionate amount of tax-free pay. For example, if an employee starts on September 1, 2023, they will be allowed £6,288 (6 months x £1,048) of pay free of tax for that month. This tax-free amount increases by £1,048 each subsequent month.


Tax Codes for Different Regions

Since April 6, 2017, Scottish taxpayers pay Scottish Income Tax, and their tax codes are prefixed with an 'S'. Similarly, there is a Welsh tax code prefixed with a 'C'. For the tax year 2023/24, the Welsh tax rates and thresholds are the same as the rest of the UK.


Emergency Tax Codes

Sometimes, you may encounter emergency tax codes like 1257L W1 or 1257L M1. These codes mean that only one week’s or month’s proportion of the allowances due for the tax year is given against each week’s/month’s pay. This is usually a temporary measure until the correct tax code is received from HMRC.


What Happens If You Use the Wrong Tax Code?

Using the wrong tax code can result in underpayment or overpayment of taxes. If an employer fails to apply the correct tax code, HMRC will first seek the tax from the employer, not the employee. It's crucial for employers to operate the tax code that HMRC provides and to make changes when instructed to do so.


Navigating Changes and Compliance

Key Takeaways from the P9X 2023 Guidance

The P9X 2023 guidance document issued by HMRC provides essential information for employers to prepare for the new tax year starting on April 6, 2023. The basic Personal Allowance remains at £12,570 for the entire UK, and the emergency tax code is 1257L for all employees. The document outlines the steps employers need to take to get ready for the new tax year, including preparing payroll records and identifying the correct tax codes for each employee.


Preparing for the New Tax Year

Employers need to prepare a payroll record for each employee who will be working for them on April 6, 2023. They must identify the correct tax code, including the correct prefix (e.g., 'S' for Scotland or 'C' for Wales), and enter this tax code into the payroll record. Employers will receive a new tax code for their employees either through a paper form P9(T) or an internet notification if they are registered to use HMRC's PAYE Online service.


Handling Employees Without a New Tax Code

For employees who do not receive a new tax code, employers should copy the authorized tax code from the 2022 to 2023 payroll record and continue to use it for the 2023 to 2024 tax year. Importantly, any 'week 1' or 'month 1' markings should not be carried over.


Handling Employees with a New Tax Code

If an employee receives a new tax code, employers should keep and use the form P9(T) or other tax code notification with the most recent date. Any older notifications for the same employee should be discarded. The new tax code should then be copied onto the payroll record.


Special Cases: Employees Leaving and New Employees

Employers do not need to change the tax code for any employee who leaves before April 6, even if they'll be paying them after that date. For new employees starting between April 6 and May 24 who provide a P45, employers should follow specific instructions available on the government website.


Manual Payroll and Basic PAYE Tools

Employers with an agreed exemption from online filing and operating a manual payroll should continue to use the Taxable Pay Tables Manual Method (April 2023). Those using HMRC’s Basic PAYE Tools will be able to action the P9X once the new tax year is available in the tool.


Staying Ahead and Ensuring Compliance


The Importance of Staying Updated

Tax codes are not static; they change due to various factors such as amendments in tax laws, changes in personal circumstances, or even due to errors. Employers must stay vigilant and keep themselves updated with the latest information from HMRC. Failing to do so can result in complications that may lead to financial penalties or legal issues.


Consequences of Non-Compliance

Ignoring or failing to implement the changes as per the P9 tax code notice can have serious repercussions. HMRC has the authority to impose fines and penalties on employers who do not comply with the tax code changes. Moreover, incorrect tax deductions can lead to dissatisfaction among employees and can tarnish the reputation of the business.


Where to Seek Further Guidance

HMRC provides various resources for employers to understand tax codes and how to implement them. Their website offers comprehensive guides, and they also provide online services like the PAYE Online for employers. Employers can also consult tax professionals for personalized advice tailored to their specific circumstances.


Final Thoughts

Understanding and implementing the P9 tax code notice is not just a legal obligation but also a responsibility that employers owe to their employees. By ensuring that the correct tax codes are used, employers contribute to the smooth functioning of the tax system, which benefits everyone involved. The year 2023 brings its own set of updates and guidelines, making it crucial for employers to pay close attention to the P9X guidance and other notifications from HMRC.
