How to Register for Self Employment if you have NOT Submitted a Personal Tax Return Previously
Registering for Self Employment is a fairly straightforward process and you can do it online yourself here.
The process can take up to 7 -10 days however and requires an activation code being posted to you, so it is advisable that you register as soon as possible so you are ready in time to submit your first personal tax return by 31 January each year and avoid penalties.
The process involves setting you up with an online account with HMRC which you will log into to submit your tax return, so keep hold of your login details as well as issuing you with a UTR (‘Unique Tax Payers Reference’), another important piece of information that you must keep safe. You will be asked questions such as your full name, address, NI number and details of your new business.
