Check your Tax Codes for the 2025/26 Tax Year
Posted on 4th April 2025
The taxman doesn't always get things right, and there have been many cases of individuals being allocated the wrong tax code. This may be due to a whole host of reasons, for example a historical benefit which you no longer receive.
Why Checking Your Tax Code Matters
A mistake in your tax code could lead to you being charged more tax than you should owe. You could even get hit with a massive tax bill at the end of the year! To avoid a surprise bill it is very important to ensure your tax code matches your situation, especially if:
You’ve changed jobs.
You have multiple sources of income (e.g., a second job or pension).
Your circumstances have changed (e.g., starting benefits or losing allowances).
How to Check Your Tax Code
Look at your payslip — it will show your tax code near the income or deductions section.
Use the HMRC online tax account to confirm the code is correct for your situation.
If something seems off, contact HMRC. They can adjust your code and issue a refund if you've overpaid.
