A guide to self-assessment

Who should register for Income Tax self-assessment?

You should register for Income Tax self-assessment if:

  • you are self-employed
  • your only or main source of income is:
  • you have profited from share options or share incentives.

You do not need to register for self-assessment if:

  • you only have PAYE income
  • or
  • your taxable non-PAYE income does not exceed €5,000 and your gross non-PAYE income does not exceed €30,000. That income must be coded for PAYE purposes. ’Coded’ means the income is taken into account in calculating your tax credits and standard rate cut-off point for PAYE purposes. In this case, you must submit a Form 12 online through PAYE Services in myAccount.

You can register for self-assessment by using the eRegistration service or completing part A and part B of Form TR1.
