Frequently asked questions

What is Self Assessment?

Self Assessment is how HMRC collects income tax from individuals who earn outside of PAYE — such as sole traders, freelancers, landlords, or anyone with untaxed income. If you meet the criteria, you must register and submit a yearly tax return.

Why do I need a UTR to register for Self Assessment?

Your Unique Taxpayer Reference (UTR) is essential for submitting a Self Assessment tax return. HMRC uses this number to track your income and tax obligations. You’ll also need one if your annual income exceeds £100,000 or if you’re self-employed.

HMRC typically takes up to 6–8 weeks to issue your UTR number. With Tax2u’s FAST TRACK service, you can receive it in as little as 10 working days, allowing you to meet your tax obligations without delay.

  • You receive income from property, dividends, crypto, or overseas assets
  • You earn more than £100,000 per year
