Very Helpful

Tax2u are professional, very helpful and easy to work with. This is my 2nd tax year they are handling, both of which, they've guided and prompted me when they needed documentation. Their online system is easy to access and use to upload documents throughout the year, making it painless to meet the HMRC deadline.

What is self assessment?

Why do I need a UTR to register for self assessment?

If you want to start working as self employed you need to apply for a Unique Taxpayer Reference (UTR) and required to submit self assessment to HMRC using your UTR number. You will also need your UTR to file a Tax Return if you earn more than £100,000 during a tax year.

Or you can simply use this online UTR form provided by Tax2u. It is simple and fast to apply online for your UTR number with Tax2u.

Once you have submitted self assessment registration through our online application form, HMRC will issue your UTR and send you a letter at home, containing your UTR number, it may take up to 6 weeks (or only 10 working days if you chose our FAST TRACK UTR Service).
