When Do I Need to File a Tax Return in Ireland?

Not everyone in Ireland needs to file a tax return. If your only income is PAYE employment and you have no other income sources, Revenue handles your tax through the PAYE system. But several situations trigger a filing obligation.

You Must File If...

• Your non-PAYE income exceeds EUR 5,000 (rental income, self-employment, investment income, foreign income)
• Your gross non-PAYE income exceeds EUR 30,000 (regardless of net amount after expenses)
• You are self-employed or a sole trader
• You are a company director with non-PAYE income
• You have disposed of an asset subject to Capital Gains Tax
• You have received a gift or inheritance above the CAT small gift exemption that needs to be declared
• Revenue has issued a notice requiring you to file

Key Deadlines

The Form 11 deadline for the 2025 tax year is 31 October 2026 (paper) or mid-November 2026 (ROS online). Preliminary tax for 2026 is also due by the same date.

What If I Only Have PAYE Income?

PAYE workers with no other income are not required to file a Form 11, but you may still benefit from filing a Form 12 (or using myAccount) to claim additional credits such as medical expenses, rent credit, or flat rate expenses.
