Enhanced Reporting Requirements(ERR) Ireland 2026
Since 1 January 2024, employers have had to report three categories of tax-free payment to Revenue on or before the date they are paid, through ROS: travel and subsistence, the small benefit exemption, and the remote working daily allowance. It comes from section 897C TCA 1997. There is no return to file at year end and no tax to pay — the obligation is the timing, and that is where businesses get caught.
This page covers what ERR is and why it exists. For the timing rules and a pre-pay-run checklist, see ERR reporting deadlines. For mileage specifically — what to report and in which category — see ERR and mileage reimbursements.
1. The "Grace Period" is Over
Why 2026 is the year of no excuses
When Enhanced Reporting Requirements (ERR) were introduced in January 2024, Revenue adopted a "Service for Compliance" approach. They understood businesses needed time to adapt. Mistakes were treated as learning opportunities.
Full enforcement began in January 2025. We are now in year two—that safety net is long gone.
Revenue's systems have matured. Their analytics can now cross-reference your ERR submissions against bank transfers, payroll records, and historical patterns in real-time. Discrepancies that would have been overlooked during the grace period now generate automatic flags for review.

2. The "On or Before" Rule: Why Manual Fails
The timing requirement that catches Excel users
The ERR Rule
You must report the expense to Revenue on or before the date you pay the employee.

3. The "Vouched vs. Unvouched" Trap
The classification that Revenue scrutinises most
Revenue requires you to split travel expenses into specific sub-categories. The distinction between vouched (receipted) and unvouched (flat-rate) expenses is critical for tax treatment.
In Excel, employees often mix these up in one column called "Expenses" or "Travel". This is exactly what triggers an audit.
Common Excel Mistake
If you report Civil Service Mileage (unvouched) as 'Vouched Travel' in 2026, you are inviting an audit. Revenue's systems specifically look for this mismatch.
Our system detects this difference automatically and prevents incorrect classification.
