Register for Self Assessment

Do you need to complete a tax return but do not have a UTR – Unique Tax Reference?

You can register yourself by visiting HMRC and accessing your Personal Tax Account.

Alternatively, we can register you and assist in getting all of your self-assessment tax affairs in order.

Penalties for late filing

The deadline is January 31st 2023. If you do not submit your tax return on time, you’ll have to pay a penalty. You’ll also have to pay interest on both the amount you owe and any penalties. These penalties are in addition to any penalties for paying your tax late.
