1250L Tax Code Meaning

If your payslip shows the 1250L tax code, then you’re on one of the most commonly used tax codes for 2020. In this guide, I’ll explain more about what the 1250l tax code means, why it’s used and how to check if it’s right for you.

What Tax Codes Mean

A tax code is a numerical number, followed by a letter, that is issued by HMRC to your employer so they know how much tax they need to deduct from your salary. HMRC have to issue it because they have all the information on your personal income and any deductions they need to take from you, meaning you can keep things confidential from your employer.

Your tax code lasts for one tax year* so both you and your employer will most likely receive a coding notice before the start of a new tax year. You and your employer may also receive a letter from HMRC to change your tax code if your circumstances change, for example, if:

* A tax year runs from the 6 April to 5 April each year

What Does the 1250l Tax Code Mean?

Each code tells your employer how much tax to deduct and the 1250L tax code is used by people with one job and no work benefits like a company car or have one pension.

Every year, all UK residents are entitled to earn an amount tax-free known as a personal allowance. For both the 2019/2020 and 2020/2021 tax years, this is £12,500. After this, you’ll pay income tax at 20% on your earnings up to £50,000 and 40% over that amount, until you reach £150,000 and have to pay 45%.

Personal allowance 0%£12,500£12,500
Basic rate 20%£12,501 to £50,000£12,501 to £50,000
Higher rate 40%£50,001 and £150,000£50,001 and £150,000
Additional rate 45%over £150,000over £150,000

For the purposes of tax coding, HMRC removes the last digit and replaces it with a letter. In this case, the letter “L” has been used which means you’re entitled to the standard tax-free Personal Allowance.

Personal Allowance

Why Did Your Tax Code Change from 1185L to 1250L?

The personal allowance in the tax year 2018/2019 was £11,850 and it has since changed to £12,500. It means you are entitled to more tax-free pay and the change in your tax code from 1185l to 1250l ensures your employer passes your tax-free pay onto you.

1250l Cumulative Tax Code

The 1250L tax code is a cumulative code. That means you’ll receive a portion of your personal allowance every time you get paid. For example, if you are paid monthly, you’ll receive £1,041,67 (£12,500 ÷ 12) tax-free each month you get paid. That way by the end of the tax year, you’ll have received your personal allowance in full.

If you took a few months of work and had no other job during the tax year, you’ll receive all the personal allowance you are owed in your first payslip if you start a new job. Your employer will know what code to use when you give them your P45.

What to Do About a Lost P45

If your tax code ends W1 (week 1), M1 (month 1) or X, then you have been put on a non-cumulative or emergency tax code.

Emergency Tax Codes 1250 W1, 1250 M1, 1250 X

If you have the tax code 1250W1, 1250M1 or 1250X then you’ve been put on an emergency tax code. This normally happens if you:

  • start a new job and not provided a P45
  • begin working for an employer after you’ve stopped self-employment
  • receive company benefits, like a company car
  • receiving the State Pension

Although emergency tax codes are temporary while the necessary information is put together, it does mean you’ll pay tax on all your income above the personal allowance and not receive any backlog of personal allowance you may be entitled to but haven’t used.

If you end the tax year on an emergency tax code, HMRC will add up how much tax you have paid and work out whether you owe anything at the end of the tax year. They will then send you an HMRC tax code notification letter called a P800 detailing what you are owed and how you’ll be repaid. If you are registered as self-employed, any money you are owed will be credited to your tax account.

How to Check If Your Tax Code Is Correct

If you think that you shouldn’t be on the 1250L tax code, then you can contact HMRC on 0300 200 3300. Alternatively, you can use the HMRC online checker, by logging into your Personal Tax Account.

Unfortunately, your employer may not be able to help you because they can only act on the information sent to them in the HMRC coding notice.

What Happens if You Haven’t Paid Enough Tax

If HMRC discovers, for whatever reason, that you have underpaid your tax during the year, they will recalculate your tax and issue you with a simple assessment if you owe less than £3,000 or send you a letter if you owe more than £3,000.

Tax Code 1250L and Self Employment

If you work for yourself, you’ll have a UTR number which is a numerical number used by HMRC for managing your self-assessment information.

If you are employed and self-employed then you may have the 1185l tax code as well as a UTR number. It means, your employer is giving you your personal allowance and that most likely all the profit you earn from your business will be taxed at your highest rate of tax.

When you fill in your tax return online, you’ll have to declare all your income in the employment and self-employment sections of your tax return. But you’ll get credit for any tax you’ve paid in your employment when HMRC calculates your tax bill.
