Today, 9th April 2025, the Revenue Commissioners updated their guidance material in relation to the Code of Practice and Compliance. Please click link: https://www.revenue.ie/en/self-assessment-and-self-employment/code-of-practice-and-compliance/index.aspx
As you’re aware, the Code of Practice for Revenue Compliance Interventions is a set of guidelines on how the Revenue Commissioners conduct compliance interventions. It covers all aspects of compliance including your right to make a qualifying disclosure.
A qualifying disclosure must contain complete information and full particulars in relation to the tax liability arising under each relevant tax head. It should be in writing and signed by the taxpayer and should also be accompanied by the correct tax payment plus corresponding interest.
Taxpayers are advised to make a qualifying disclosure to:
1. lower the level of tax penalty,
2. prevent the settlement from being published by Revenue and thereby avoid your name appearing as a Tax Defaulter, and
3. prevent prosecution as the Revenue Commissioners, generally, won’t initiate an investigation with a view to prosecution.
