How do I register for Tax as a self-employed person?

You should advise the tax office when you start a business as a self-employed person/sole trader. You must do this online using the Revenue Online Service – ROS, through the online eRegistration Service if you are:

  • An individual who is currently registered for PAYE Anytime;
  • An individual who is currently registered for Revenue’s Online Service – ROS;
  • Represented by an Agent.

ROS is Revenue’s internet facility which provides you with a quick and secure facility to register for tax, pay tax liabilities, file tax returns, access your tax details and claim repayments. The facilities are available 24 hours a day, 7 days a week, and 365 days a year. You will also benefit from an extension to existing deadlines for paying tax and filing returns where you both pay and file using ROS. Further information on Revenue’s online service can be found at ROS.

There are a limited number of customers where paper registration applications are still accepted - you will find details of those customers at eRegistration Service.
