How to Appeal an Irish Revenue Surcharge or Penalty
Receiving a surcharge or penalty notice from Revenue is stressful — especially if you believe it was applied in error or is disproportionate to the circumstances. The good news is that both surcharges and penalties are appealable in Ireland under Part 40A of the Taxes Consolidation Act 1997.
This guide explains what surcharges and penalties Revenue can impose, the grounds on which you can appeal them, and exactly how to do it.
Act within 30 days. Under section 949I of the Taxes Consolidation Act 1997, your notice of appeal must reach the Tax Appeals Commission within 30 days of the date on Revenue's notice. This deadline is counted from the date on the notice — not the date you received it.
What is a Revenue Surcharge?
A surcharge is an additional amount added to your tax liability as a consequence of a default — most commonly the late filing of a tax return. The most common surcharges are:
Late Filing Surcharge (Section 1084 TCA 1997)
If you file your income tax or corporation tax return late, Revenue can impose a surcharge of:
- 5% of the tax due (up to €12,695) if the return is filed within 2 months of the deadline
- 10% of the tax due (up to €63,485) if the return is filed more than 2 months late
This surcharge is applied to the tax due for the period, not to the tax paid — it can be significant even when the underlying tax liability is relatively small.
Other Surcharges
Surcharges can also arise from other compliance failures, including failure to keep proper records, failure to register for tax, and certain deficiencies identified during a Revenue audit.
What is a Revenue Penalty?
A penalty is a financial charge imposed by Revenue for a specific non-compliance, separate from the tax itself and from surcharges. Common Revenue penalties include:
- Incorrect return penalties — for filing a materially incorrect tax return
- Failure to register penalties — for not registering for VAT, PAYE, or other taxes when required
- Failure to deliver a return penalties — for not filing at all
- Offshore penalties — for failures relating to offshore assets or accounts
Revenue has a structured penalty system under the Taxes Consolidation Act 1997. The level of penalty depends on the nature and severity of the default, and whether it was deliberate or careless.
Can I Appeal a Surcharge or Penalty?
Yes. Under Part 40A of the Taxes Consolidation Act 1997, both surcharges and penalties imposed by Revenue are subject to appeal to the Tax Appeals Commission. The same 30-day deadline and process applies as for any other Revenue assessment.
The Tax Appeals Commission can:
- Reduce the surcharge or penalty
- Discharge it entirely if it was wrongly applied
- Confirm it if Revenue's decision was correct
Grounds for Appealing a Surcharge
The most common grounds for appealing a late filing surcharge are:
The return was filed on time
Revenue's systems sometimes fail to correctly register a return that was submitted on time, particularly if filed electronically close to the deadline. If you can demonstrate with evidence (submission confirmation, timestamp, ROS record) that the return was filed before the deadline, the surcharge should not stand.
The filing deadline was extended or agreed
In some cases, Revenue grants filing extensions for specific categories of taxpayers, during national emergencies, or by specific agreement. If your deadline was formally extended and Revenue applied the surcharge anyway, that is grounds for appeal.
Reasonable excuse
While the Taxes Consolidation Act 1997 does not have a general "reasonable excuse" defence for surcharges in the same way as UK tax law, the Tax Appeals Commission can consider the circumstances. Documented illness, bereavement or a situation entirely outside your control may be relevant.
The underlying liability is zero or nominal
Where a surcharge is applied as a percentage of tax due, and the underlying tax liability was in fact nil or negligible, the surcharge may be reduced accordingly.
Grounds for Appealing a Penalty
The most common grounds for appealing a Revenue penalty are:
The penalty is disproportionate
Revenue's penalty regime is structured, but there is discretion in its application. If the penalty imposed is disproportionate to the nature of the default — particularly where the error was genuinely inadvertent and Revenue has suffered no material loss — this is arguable before the Commission.
The error was not deliberate
Revenue distinguishes between deliberate and careless non-compliance. The penalty for a deliberate incorrect return is higher than for a careless error. If Revenue categorised your default as deliberate when it was in fact a genuine mistake, that classification is appealable.
Cooperation and disclosure
Revenue's penalty mitigation provisions reduce penalties for taxpayers who make voluntary disclosures or cooperate fully with an investigation. If you cooperated and the full mitigation was not applied, that is a ground of appeal.
The underlying assessment is wrong
If the penalty arises from an incorrect return that you dispute, you can appeal both the underlying assessment and the penalty together. The penalty should fall or be reduced if the assessment itself is revised.
How to Draft Your Notice of Appeal
Your notice of appeal to the Tax Appeals Commission must:
- Identify the surcharge or penalty reference and the relevant notice from Revenue
- State the tax head and period
- Set out each ground of appeal clearly and separately
- State that the appeal is made within the 30-day window under section 949I of the Taxes Consolidation Act 1997
- Request that the surcharge or penalty be discharged or reduced
The quality of your grounds of appeal matters. The Tax Appeals Commission decides by reference to what you set out in your notice — a vague or incomplete notice makes a successful outcome harder. Be specific about why the surcharge or penalty should not stand.
What Evidence Should I Gather?
Before lodging your appeal, gather any evidence that supports your grounds:
- ROS submission confirmation or timestamp
- Your own filed return or filing confirmation
- Any correspondence with Revenue about the deadline or the return
- Medical or other evidence if illness was a factor
- Accountant's records if the return was filed through a third party
You do not need to submit all evidence with your initial notice of appeal. The Commission will allow you to submit it in the course of the appeal process. But knowing what you have strengthens your grounds.
