On this form you will need to know your website URL, business name, telephone number, and PPSN.
When completing the TR1 form, you will usually need to complete the following sections to register as a sole trader: A1, A4, Part B and Sign the Declaration on page 4 of the form.
Most individuals will not need to register for VAT or as an Employer to begin with. If this changes, you can complete a further TR1 at a later date. You should then either take the form into your Local Revenue Office or post it off.
You can view guidance notes about completing your tax registration on the Revenue Website.
