Revenue Penalties · 20 Questions

Revenue Penalty FAQ Ireland 2026

The most common questions about Revenue surcharges, late payment interest, appeals and voluntary disclosure — answered based on current Irish tax law.

What is a Revenue surcharge?

A Revenue surcharge is an automatic additional charge applied when a tax return is filed after its statutory deadline. The surcharge is 10% of the tax owed if the return is up to 2 months late, and 20% if it is more than 2 months late, capped at €63,493 (TCA 1997 s1084).

What triggers the late filing surcharge?

Any tax return filed after its statutory deadline. For self-assessed income tax (Form 11), the deadline is 31 October. For ROS filers, the deadline is extended (typically mid-November). For corporation tax (CT1), the deadline is 9 months after the accounting period end. One day late is enough to trigger the 10% surcharge.

What is the Revenue late payment interest rate?

Revenue charges 0.0219% per day on unpaid tax — approximately 8% per annum. This is set under TCA 1997 s1080 and there is no cap. Interest starts from the date the tax was due and accrues daily until paid.

Can the late filing surcharge and late payment interest both apply at the same time?

Yes. They are separate charges. If you file late AND pay late, both the surcharge (s1084) and daily interest (s1080) apply simultaneously. Filing the return as soon as possible stops the surcharge rate from moving from 10% to 20%, even if you cannot pay immediately.

What is the maximum Revenue penalty?

The maximum civil penalty is 100% of the tax understated — Revenue doubles what you owe. This applies where the non-compliance was deliberate and no voluntary disclosure was made. Adding late payment interest, the total liability can exceed the original tax amount by a large margin.

Can I appeal a Revenue penalty?

Yes. Most Revenue penalties and assessments can be appealed to the Tax Appeals Commission (TAC) within 30 days of the Revenue notice. The TAC is an independent body — it can uphold, reduce or overturn Revenue decisions. Lodge the appeal within the deadline even if your grounds are not fully developed.

What is voluntary disclosure?

A voluntary disclosure is when a taxpayer formally tells Revenue about a tax irregularity before Revenue discovers it through an audit. An unprompted qualifying disclosure reduces the penalty to 10% of the tax owed and eliminates criminal prosecution risk. A prompted disclosure (after Revenue contacts you) reduces the penalty to 30%.

How do I make a voluntary disclosure to Revenue?

Write formally to your Revenue District identifying the tax heads, periods, amounts and nature of the irregularity. The disclosure must be complete and include payment (or a firm payment proposal). An accountant can prepare the disclosure letter to ensure it qualifies for penalty mitigation.

Will a Revenue penalty affect my credit rating?

A Revenue penalty itself does not directly affect your credit rating. However, if Revenue pursues collection through the courts or the sheriff, this could lead to judgments that appear in public records. In extreme cases, taxpayers can be listed on the Revenue Tax Defaulters List — which is public.

What is the Revenue Tax Defaulters List?

Revenue publishes a quarterly list of tax defaulters — individuals and businesses that have settled tax liabilities above €35,000 where penalties were imposed. Publication on this list is public. It can be avoided by making a voluntary disclosure before audit, which prevents Revenue from publishing the name.

How many years back can Revenue audit me?

Revenue can generally audit the previous 4 years. However, where Revenue believes there has been fraud or neglect, there is no time limit — Revenue can go back indefinitely. For a standard compliance check, the 4-year lookback applies.

What should I do if I receive a Revenue audit notification?

Do not ignore it. Read it carefully to identify the tax type, period and purpose. You generally have a short window to make a prompted voluntary disclosure, which significantly reduces penalties. Contact a tax accountant immediately — before responding to Revenue.

Can Revenue take money from my bank account?

Yes. Revenue has the power of attachment, which allows it to instruct your bank to transfer funds directly to Revenue without a court order, after formal notice. This is one of several enforcement mechanisms available after standard demand notices are ignored.

Is Revenue interest tax deductible?

No. Interest paid to Revenue on late payment of tax (s1080 interest) is not deductible from income or profits for tax purposes. You pay it entirely out of after-tax money.

Can I negotiate a payment plan with Revenue?

Yes. Revenue will often agree to phased payment arrangements where a taxpayer is unable to pay in full. Contact Revenue before the debt becomes subject to enforcement. Revenue's Debt Management Unit handles these arrangements. An accountant can negotiate on your behalf.

What is the difference between a civil penalty and a criminal prosecution?

Civil penalties (surcharges, interest, s1077E penalties) are financial sanctions imposed on the tax liability. Criminal prosecution is a separate track — used only for deliberate fraud. A qualifying voluntary disclosure eliminates the criminal prosecution risk and converts the liability to a civil settlement.

Does the Revenue surcharge apply to VAT?

Yes. A surcharge under s1084 can apply to VAT returns filed late, at the same 10%/20% rates. VAT returns are typically bi-monthly and have a deadline of the 19th of the month following the VAT period end.

What is the €63,493 cap on surcharges?

The late filing surcharge under s1084 is capped at €63,493 per return. This means that for very large tax liabilities, the surcharge cannot exceed this amount — even if 20% of the tax would be much higher. For example, if you owe €500,000 and file more than 2 months late, the surcharge is €63,493, not €100,000.

Can I make a voluntary disclosure for all years at once?

Yes — in fact, this is recommended. A comprehensive disclosure covering all periods and all tax heads at once is more likely to qualify as a full qualifying disclosure. Doing them piecemeal risks Revenue concluding that the disclosure was not complete.

Where can I find official Revenue penalty guidance?

Revenue publishes Tax and Duty Manuals on revenue.ie covering all penalty provisions. Key manuals: TCA 1997 s1080 (interest on late payment), s1084 (surcharges), s1077E (civil penalties for non-disclosure). These are publicly available without registration.

Should I get professional help when facing a Revenue penalty?

Yes — especially if the amount is significant or if Revenue has been in contact. The window between a Revenue audit notification and the close of the compliance check is short. Voluntary disclosures must be complete and properly prepared to qualify for penalty mitigation. D'Emilia Accounting handles Revenue correspondence, voluntary disclosures, and penalty negotiations.
