Every person running a business in the United Kingdom and every Ltd company receives a Unique Taxpayer Reference (UTR) from HMRC once registered for the relevant taxes. This is a ten-digit identification number used in dealings with HMRC, for example when filing Self Assessment returns, reporting Corporation Tax, making tax payments or working with an accountant. 👇
The UTR is issued after registering for Self Assessment (for individuals) or after registering a company for Corporation Tax. Not every company director receives one automatically - only if they are required to submit a tax return or register for Self Assessment. 📄
After registration, the UTR is sent by post to the registered address. This usually takes around 10–15 working days within the UK, while for overseas addresses it may take several weeks.
The UTR is essential for proper tax compliance and communication with HMRC. If you have questions about registration or running a business in the UK, contact our office - we will be happy to help and explain everything. 😉
