Protected disclosures made to Revenue up 40% in 2025 

Some 241 protected disclosures were made to Revenue last year, up from 171 in 2024

Revenue said the report showed a continued year-on-year increase in the number of disclosures received by Revenue through its external reporting channels regarding potential tax or duty non-compliance.

The number of protected disclosures received by Revenue grew by more than 40% last year, a new report by the agency has revealed. 

A total of 241 protected disclosures were made to Revenue last year, up from 171 in 2024. 

The agency's new annual report published on Tuesday includes information on both internal and external protected disclosures received in 2025.

Internal protected disclosures are reports made by current or former Revenue staff members that relate to potential wrongdoing, occurring within Revenue. Meanwhile, external protected disclosures are reports made by workers who are employed by a business, individual or organisation, other than Revenue, that contain information about potential wrongdoing related to tax, duty or customs controls. 

Revenue said the report showed a continued year-on-year increase in the number of disclosures received by the agency through its external reporting channels regarding potential tax or duty non-compliance.

The agency said when it first receives a report through its external reporting channels, it is assessed to determine if it meets the criteria to be considered as a protected disclosure. 

Revenue said it received a total of 1,743 reports by the end of last year, with 241 of these meeting the criteria to be considered a protected disclosure. While the remainder of the 1,743 reports received didn’t meet the criteria to be considered as a protected disclosure, the vast majority related to reports of tax evasion not encountered in a work-related setting.

Revenue said it can confirm at a "high level" that the outcomes of these compliance interventions can be monetary, non-monetary or both. 

"For example, compliance interventions opened on foot of protected disclosure reports received yielded over €1.5m in additional taxes for the Exchequer in 2025," said Revenue director of internal audit, Leeann Kennedy, who is prescribed to receive external disclosures on matters related to tax, duty or customs controls.

"Other outcomes included initiation of summary prosecutions in respect of excise offences, new tax registrations, withdrawal or cessation of a tax registration and debt collection via Phased Payment Arrangements.”
