P9 and P6 Tax Code Changes for 2025: Calculation and Benefits for Employers in the UK

What is P9 and P6 Tax Code Changes

In the UK, P9 tax code notices are official documents issued by HMRC to inform employers about changes to an employee’s tax code. These notices update employers with the necessary details to ensure correct PAYE (Pay As You Earn) deductions. For the 2025 tax year, there are notable changes that both employers and employees need to understand to avoid any errors in tax deductions.

A P9 tax code notice is typically issued when an employee’s tax code changes. It could be due to various reasons, such as salary adjustments, changes in tax-free allowances, or updates to personal circumstances. The 2025 updates will ensure that tax codes are applied correctly, preventing over or under-deductions in PAYE.

In 2025, the way P9 notices are issued and processed may shift slightly to accommodate the ongoing changes to the tax system. Employers should remain vigilant to ensure they apply the updated codes and avoid mistakes that could lead to costly fines.

How Do P6 Coding Notices Differ From P9 Notices in 2025?

The P6 and P9 tax code notices serve different purposes and are issued under different circumstances:

P9 Notices
P9 tax code notices are sent by HMRC to notify employers about tax code changes for an employee, typically after an error or when an individual’s circumstances change. This can happen when an employee is incorrectly taxed due to a wrong tax code, prompting a revision.

P6 Notices
P6 notices are issued by HMRC during the tax year to inform employers of changes to an individual employee’s tax code. They are triggered by adjustments to personal allowances, benefits, or corrections to previous tax deductions. Employers must promptly update the affected employee’s payroll records to ensure correct tax deductions going forward.
