A Unique Taxpayer Reference (or UTR) number is a ten-digit code that’s unique to you and will remain the same number throughout your life.
It identifies you with HMRC for anything to do with your tax obligations. It provides them with an easy way to match and monitor records to payments. You could also get a tax refund if you’ve overpaid any tax.
You’ll need your UTR number to complete Self Assessment Tax Returns.
Once your business is registered at HMRC your UTR number is posted directly to your address usually in 3 to 4 weeks but it can take longer (up to 8) depending on how busy they are.
Do I need a UTR number if I’m a sole trader but not earning above the tax threshold?
If you are registered as sole trader with HMRC you will have been issued with a UTR and typically need to file a self-assessment even if you have not met the threshold. This is to keep your tax records up to date.
If you are not officially registered as a sole trader and are below the tax threshold you might still need a UTR number for filing self-assessment. To ensure everything is correctly recorded with HMRC you may need to report income received through sources such as rental income, income from savings and investments, or freelance income. It’s best to check with an accountant.
