A UTR or Unique Tax Reference is a number assigned to your company by HMRC. This number is assigned automatically after the company is registered with Companies House (usually within 28 days) and is the number that HMRC uses to identify your company as a tax payer.

Shortly after registration HMRC will send you a letter containing your UTR number and will reference this number on the majority of correspondence going forward.

Please note, if you are a director, you will have your own personal UTR number also, which relates to your personal tax affairs.
