Check Your Tax Code Now: Avoid Overpaying or Underpaying


The start of a new tax year often brings a new tax code from HMRC. This seemingly random string of numbers and letters holds the key to how much income tax you'll pay. Changes to the Personal Allowance (the amount of income you can earn tax-free), a well-deserved pay rise, starting a pension, or even a simple job change can all prompt HMRC to update your code.


While it might not seem like a big deal, an incorrect tax code throws your whole financial plan off-kilter. Overpaying means unnecessarily tying up your money and waiting for a refund from HMRC. Underpaying, on the other hand, leaves you vulnerable to a surprise tax bill at the end of the year – not the kind of shock anyone wants! Taking the time to verify your code now ensures a smoother financial journey throughout the year. 

The Cost of Mistakes: More Than Just Money

An incorrect tax code isn't just a financial inconvenience – it can have real consequences for your well-being. Here's why getting it right matters

  • Cash Flow Complications: Overpaying tax might seem like a minor issue, but it means your hard-earned cash is stuck with HMRC instead of where it belongs – in your pocket. This can disrupt your budgeting, make it harder to cover expenses, or even delay important financial goals.

  • The Stress of Unexpected Bills: Underpaying taxes is far worse. While no one enjoys paying taxes, at least it's predictable when done correctly. Owing HMRC a lump sum at the end of the tax year can create immense financial strain and worry.

  • Missed Opportunities: Whether you're overpaying or underpaying, a wrong tax code means money isn't working as effectively as it could for you. An overpayment might delay savings or investments, while an underpayment could lead to unnecessary debt or penalties.

Prevention is Key: The stress and financial strain of tax code mistakes are easily avoidable. Taking a few minutes to check your code now gives you peace of mind and ensures your money is working for you, not against you.

Decoding Your Tax Code

Your tax code looks like a mix of numbers and letters (e.g., 1257L). Here's what it signifies:

  • Numbers: Represent your tax-free Personal Allowance. The standard for the current tax year is £12,570.

  • Letters: Indicate various adjustments to your allowance. Here are some common examples: For a full breakdown of letters and their meanings, visit the website.

    • L: You're entitled to the standard Personal Allowance.

    • K: Additional tax is owed from previous years.

    • BR: All income is taxed at the basic rate.

How to Verify Your Tax Code

  1. Employer/HR: Your employer's payroll department or HR can provide your current tax code.

  2. Payslips/P60: Your tax code should be on your payslips and your P60 (your end-of-year tax summary).

  3. HMRC Online: You can log into your HMRC account to see your tax code.

  4. Accountant: For the most reliable assistance, your accountant can review your code and ensure everything is in order.
