Is there a time limit for claiming tax refunds?

Yes, there is a four-year time limit to claim tax refunds in Ireland. You must submit your claim within four years from the end of the relevant tax year.

For example:

• Claims for the 2021 tax year must be submitted by 31 December 2025.
• Claims for the 2025 tax year must be submitted by 31 December 2029.

If you miss the four-year deadline, Revenue will not accept your claim. Be sure to gather all necessary documents, such as proof of tax paid abroad and evidence of your Irish tax residency, to support your claim.
