The deadline for paper returns – for both Form 11 and Form 12 – is October 31st.

If you choose to pay and file online you have until November 14th.

By 31 October in a tax year, you must:

  • pay your preliminary tax for that year
  • file your tax return and self-assessment for the previous tax year
  • pay any balance of tax due for the previous year

When you pay and file through the Revenue Online Service (ROS), the 31 October deadline is extended to mid-November. The due dates for Capital Gains Tax (CGT) are different to those for Income Tax (IT).

You will have to pay a surcharge if you send your tax return after the deadline, as follows:

  • within two months of the filing date: 5% of your tax due, up to €12,695
  • over two months: 10% of your tax, up to €63,485.

Note that even if you pay and file on time for Income Tax, a 5% surcharge may apply if your Local Property Tax (LPT) obligations are not met.

Speak to one of our Tax Team today and they will assist you with your filing.
