What each penalty type means

Late filing surcharge (TCA 1997 s1084)

Triggered automatically when you file a tax return after the statutory deadline. The rate is 10% for the first 2 months of delay and rises to 20% thereafter. The surcharge is capped at €63,493 regardless of how large the tax owed is.

Late payment interest (TCA 1997 s1080)

Revenue charges 0.0219% per day on unpaid tax from the date it was due. There is no cap — interest accrues every day until payment. On €20,000 unpaid for one year, interest alone is approximately €1,599.

Deliberate non-disclosure

The maximum civil penalty is 100% of the tax understated — meaning Revenue doubles what you owe. This applies where Revenue can prove that the non-compliance was deliberate, not accidental. A voluntary disclosure before a Revenue audit can reduce this to as low as 10%.
