In this week’s Blog Nuala McGowan, CPA, ACA, AIA and founder of McGowan Accountancy Services explains the basic principles of the self-assessment system as it applies to Income Tax and points to some useful links on the Revenue.ie website.

The basic principles of the self-assessment system as it applies to Income Tax are covered on the Revenue.ie website on this link:

There is information about:

Under self-assessment, there is a common date for the payment of tax and the filing of tax returns. You must file your tax return on, or before, 31 October in the year after the year to which the return relates. This system, which is known as Pay and File, requires you to:

  • file your return for the previous year

  • make a self-assessment for that year

  • pay the balance of tax for that year

  • and

  • pay preliminary tax for the current year.

You must self-assess when filing your annual Income Tax Return. An exception is made where you file a paper return on, or before, 31 August within the tax year. Further information on filing an Income Tax Return (Form 11) can be found on Filing your tax return.

Most individuals must file their Income Tax Return (Form 11) online through the Revenue Online Service (ROS). There is additional information on Mandatory electronic payment of taxes and filing of tax returns in the Starting a Business section.
