A UTR number is a \u2018Unique Taxpayer Reference\u2019 assigned by HMRC to a company, a partnership, an organisation, or an individual who registers for Self Assessment.<\/p>\n
Often simply called a \u2018tax reference\u2019, a UTR number comprises 10 digits. HMRC uses UTRs to identify businesses and certain individuals for tax purposes.<\/p>\n
A UTR number is required by businesses, organisations, and many individuals in the UK, including:<\/p>\n
HMRC will automatically issue a Unique Taxpayer Reference when you set up a limited company or register for Self Assessment. Your UTR should arrive by post within 14 working days of setting up a company or within 10 working days (21 days for non-UK addresses) of enrolling for Self Assessment, although it can take longer.<\/p>\n
It will be sent to your company\u2019s registered office address or the contact address you supply during Self Assessment enrolment. The letter you receive will also provide guidance on what to do next.<\/p>\n
If you register a limited company, either directly with Companies House or through an online company formation agent, HMRC will be notified immediately. Your company\u2019s UTR will then be automatically generated and posted to your registered office, so there is no need to apply for this number separately.<\/p>\n
