Irish Revenue has updated its guidelines on interest for late tax payments, now covering Capital Acquisitions Tax. The eBrief clarifies interest rules, removes mentions of Fixed Direct Debit and Balloon payments, and updates due dates for self-assessed taxes.

Irish Revenue has issued eBrief No. 099/25 on 14 May 2025, outlining updates to its Guidelines for charging interest on late payment through Revenue Debt Management Services (DMS).

The revised guidance explains the basis for charging interest and how it is applied across various tax types, including income tax, corporation tax, capital gains tax, VAT, and now capital acquisitions tax.

The updated Tax and Duty Manual also includes changes such as the removal of references to Fixed Direct Debit and Balloon payments.

Appendix 4 – Due Dates for Self Assessed Taxes, updated for current practices.

Late payment of tax causes a considerable drain on the Exchequer. Revenue charges Interest on Late Payment (ILP) to:

  •  Penalise those who pay late
  •  Ensure that those who pay late do not gain a commercial advantage over those who pay on time
  •  Encourage taxpayers to pay on time in future.
