Who needs to register for Self Assessment?

You typically need to register if you're self-employed, a partner in a partnership, a landlord, a company director with income to report (such as dividends), or you have other untaxed income. We assess your situation and register you if you need to.

What is the registration deadline?

You must usually register for Self Assessment by 5 October following the end of the tax year (which runs to 5 April) in which you first had income to report. Registering late can lead to a failure-to-notify penalty, so we register you in good time.

A Unique Taxpayer Reference (UTR) is the 10-digit number HMRC issues when you register for Self Assessment. You need it to file your tax return. We handle the registration so your UTR is set up correctly.

Do I need this if I'm a company director?

Often, yes — particularly if you receive dividends or other income that isn't fully taxed at source. We advise on whether you need to register and, if so, handle it for you, then help with your annual return.

How it works

Step 1: Check whether you need to register

We confirm whether you need to file a Self Assessment tax return — for example if you're a director drawing dividends, self-employed, a landlord, or have other untaxed income — and register you for the right reason.

Step 2: Register you with HMRC

We complete your Self Assessment registration with HMRC so you're issued a Unique Taxpayer Reference (UTR) and set up to file, well before the deadline.

Step 3: Ready to file

Once you're registered, we can prepare and file your Self Assessment tax return each year — so registration flows straight into a return that's filed accurately and on time.
