How Do I Find Out My Tax Code?

Here’s how you can find your tax code in the UK:

Check Your Payslip

Your tax code should be printed on your payslip. If you’re unable to find your tax code on your payslip, you can try the following options.

Tax Code Notice Letter

If you receive a ‘Tax Code Notice’ letter from HMRC, your tax code should be printed on the letter.

Contact HMRC

If you’re unable to find your tax code, you can contact HMRC for assistance. There are several options to contact HMRC:

Phone

0300 200 3300 (Monday to Friday, 8 am to 6 pm)

Post

Pay As You Earn and Self Assessment, HM Revenue and Customs, BX9 1AS, United Kingdom

Online

You can also use the ‘Check your Income Tax’ service online to find your tax code. You will need to sign into your tax account to access this service.

Types of Emergency Tax Codes

There are two types of emergency tax codes:

1. 0T (zero T): This code is used when you’ve started a new job, and your employer doesn’t have your correct tax details.
2. W1 or M1: These codes are used if you’ve had a change in your circumstances, like a new job or a change in your income.

To get off an emergency tax code, you’ll need to:

1. Fill in a ‘Starting a new job’ form (P46) and give it to your employer.
2. Register for a personal tax account online and update your details.
3. Contact HMRC and provide them with your correct tax details.

Emergency tax codes are temporary, and you should be taken off them once HMRC has the correct information. If you’re still on an emergency tax code after a few months, contact HMRC to check what’s going on. Keep in mind that emergency tax codes can affect your take-home pay. So it’s essential to sort it out as soon as possible to avoid overpaying tax.
