Corrections Policy

Why deadline corrections are urgent

An incorrect deadline date on this site is more consequential than most editorial errors. A reader who relies on a wrong date and misses a Revenue filing could face a 5% or 10% surcharge on their full tax liability for the year. We treat deadline corrections as priority updates — not something that waits for the next scheduled review.

Revenue adjusts deadlines more often than most people realise: weekend adjustments, ROS extensions, Budget-year changes, and occasional one-off announcements can all affect a date that was accurate when we last verified it. Readers who are close to the deadlines — accountants, bookkeepers, or individuals who track Revenue dates closely — are often the first to notice when something has changed.

What qualifies as a correction

• Incorrect deadline date — the date shown does not match Revenue's current published deadline for that filing or payment
• Missing ROS extension — a deadline that should show an extended ROS date does not show it, or shows the wrong extended date
• Wrong description of what a deadline applies to — for example, a date described as applying to all self-employed taxpayers that actually only applies to a specific category
• Outdated surcharge or interest information — the financial consequences described for a missed deadline no longer match Revenue's current rules
• Broken link to a Revenue source page
• Omitted deadline — a Revenue deadline that should be on the calendar is missing

How to submit a correction

Email contact@demiliaaccounting.ie with:

In the email:

• The page URL and which deadline you are referring to
• The date currently shown on the site
• The date you believe is correct
• A link to the Revenue source confirming the correct date — this can be Revenue's key dates page, a ROS notice, or a Revenue press release

If you cannot find a written Revenue source but have recent direct experience of the correct date (for example, you just filed and ROS showed a different deadline than what this site lists), please include that detail. We will verify it directly with Revenue's published information.

Our review process

1. Acknowledgement within one working day for deadline corrections (two working days for other types of correction).
2. Verification against Revenue's published key dates, ROS notices, and the relevant TDM. Given the specific and verifiable nature of deadline dates, verification is typically straightforward.
3. Update of the calendar if the correction is confirmed. Deadline date corrections are treated as priority and applied the same day wherever possible.
4. Response to the submitter confirming the outcome.

How corrections are marked

Deadline date corrections are applied immediately and noted with a revision date. We do not make silent changes to dates — if a date is corrected, the calendar carries a note showing the date it was last verified. Material corrections are recorded in the log below.
