What Is a UTR Number and Why Do You Need It?

 A UTR number is a 10-digit code that HMRC assigns to every self-assessment taxpayer in the UK. This is the number the tax authority uses to trace your records, though it remains constant for life. Sometimes, a letter 'K' may follow this number.

This number works much like your National Insurance number: once you are assigned one, it remains constant for your lifetime.

Who Needs a UTR Number and When?

You only need a UTR number if you need to file a self-assessment tax return. This may apply if one of the following applies to you: you are self-employed, you work via a limited company, you have savings or investment income that bears tax, or if your total income that is taxable exceeds £100,000.

Other events may also require you to file a tax return where again a UTR number would be expected of you.

How to Obtain a UTR Number

Not all taxpayers are automatically allocated a UTR number; you must register yourself for self-assessment to get one. You can do this in any of the following ways:

Register Online: It is fairly easy to register for self-assessment on the HMRC website. If you have done this, your UTR number will be sent to you by post.

Request by Phone: The application can be made to HMRC at 0300 200 3310. For this, you may be requested to provide some of your personal information. However, they may also suggest making this application online.

Apply via Post: You may also apply in writing to HMRC to get your UTR number. This is somewhat cumbersome because you may need to exchange several letters in order to provide more information.

Timeframe for Receiving Your UTR Number

Normally, it takes 10 working days after your registration for self-assessment that you will get your UTR number if you are residing in the UK, or within 21 working days if you are abroad.

What Information Do You Need to Apply?

To register using a UTR number, you will need to give some personal details. These include the following:

• Full name
• Current address
• National Insurance number
• Date of birth
• Contact information (phone number and email)

If you are self-employed, you may also need:

• The date you became self-employed
• Business details, including address and phone number

Lost Your UTR Number? Here's What to Do

If you have a UTR number but cannot find it, then you can check it via your personal tax account using the HMRC app. HMRC has provided a YouTube tutorial for locating your UTR number via the app.

Alternatively, you can contact HMRC's self-assessment helpline on 0300 200 3310 to help find your UTR number. Have your National Insurance number to hand. Note that HMRC cannot provide the number over the phone, and it will be mailed to you, which may take up to 15 days.

Conclusion

Please note that if one submits a tax return without a UTR number, one could be looking at a fine due to the fact that probably HMRC would not be in a position to make a link of one's return with their records in time.
