Late filing surcharges, late payment interest, civil penalties and what you can do to reduce or appeal them. All based on current Revenue rules.
The most common Revenue penalty is the late filing surcharge. It applies automatically when you file a tax return after the statutory deadline:
The surcharge is calculated as a percentage of the chargeable tax for the period, not just the tax owed after credits. It is capped at €63,493.
| Tax owed | 10% surcharge | 20% surcharge |
|---|---|---|
| €5,000 | €500 | €1,000 |
| €15,000 | €1,500 | €3,000 |
| €50,000 | €5,000 | €10,000 |
| €100,000 | €10,000 | €20,000 |
| €400,000+ | €63,493 (cap) | €63,493 (cap) |
The surcharge applies to: Form 11 (income tax), CT1 (corporation tax), P35 (employer annual return), PSWT (professional services withholding tax) and VAT returns (where applicable).
Separately from the surcharge, Revenue charges interest at 0.0219% per day on any tax that remains unpaid after the due date. This is approximately 8% per annum. Unlike the surcharge, there is no cap — interest accumulates daily until the tax is paid in full.
For example: €20,000 unpaid for 180 days = €20,000 × 0.0219% × 180 = €788.40 in interest.
Where Revenue identifies an understatement of tax through an audit or investigation, civil penalties apply under TCA 1997 s1077E:
| Category | Maximum penalty |
|---|---|
| Prompted qualifying disclosure (before Revenue contacts you) | 10% of tax |
| Qualifying disclosure (unprompted, within 2 months of Revenue contact) | 30% of tax |
| Non-qualifying disclosure (prompted) | 75% of tax |
| Deliberate non-disclosure | 100% of tax |
The penalty is in addition to the unpaid tax and any interest on late payment.
Identify the type of penalty, the tax period and amount, and the response deadline. Do not ignore a Revenue notice.
You may agree with the penalty (and pay), dispute it (appeal), or negotiate a payment arrangement. An accountant can help assess all three options.
Most Revenue notices give 30 days to respond. Missing the response deadline strengthens Revenue's position.
If the audit has not yet concluded, there may still be an opportunity for a voluntary disclosure that reduces the penalty rate.
If you disagree with the penalty, you have the right to appeal to the Tax Appeals Commission (TAC). Appeals must be lodged within specified time limits.
Revenue penalties can be reduced through voluntary disclosure or appealed to the Tax Appeals Commission. Speak to D’Emilia Accounting before paying or responding to Revenue — the timing determines your options.
A surcharge is triggered when you file a tax return late — after the statutory filing deadline. The most common deadlines are 31 October for self-assessed income tax (Form 11) and 23 November if filing via ROS. Filing even one day late can trigger the 10% surcharge.
Yes. A surcharge is automatically applied when a return is filed late — it is calculated as a percentage of the tax owed for that period. A penalty is a separate civil sanction that Revenue can impose for non-compliance, incorrect returns or non-disclosure of income.
Revenue charges interest of 0.0219% per day (approximately 8% per year) on unpaid tax under section 1080 of the Taxes Consolidation Act 1997. This accrues daily from the date the tax was due and there is no cap.
Yes. Revenue has extensive enforcement powers including sheriff enforcement, court proceedings, attachment of bank accounts and publication on the Revenue defaulters list. Seek professional advice immediately if you receive a formal demand.
A qualifying disclosure (also called a voluntary disclosure) is a formal notification to Revenue about tax irregularities, made before Revenue contacts you. Under TCA 1997 s1077E, a qualifying disclosure reduces the applicable penalty by up to 75% and eliminates the risk of criminal prosecution.
Yes. Revenue has a Debt Warehousing Scheme for certain liabilities and will in many cases agree to phased payment arrangements. An accountant can negotiate on your behalf. Penalties and interest may be reduced if you engage early and show willingness to comply.
