Main Categories of VAT Penalties

  1. Criminal fiscal penalties — for breaching formal obligations under the KKS (Penal Fiscal Code)
  2. Additional tax liability — 30%, 20%, or 100% of the irregularity amount
  3. Interest — on arrears, accruing daily
  4. VAT refund suspension — when the tax office has doubts
  5. Criminal liability — for VAT fraud (up to 25 years of imprisonment)

Penalties for Missing or Late JPK_V7M (Standard Audit File for VAT) Filing

Failure to file a return constitutes a criminal fiscal offence:

  • 1–30 days late: fine up to PLN 5,800 (minor fine)
  • 31–180 days: up to PLN 5,800 / minor fine, or 1/180 of the maximum annual penalty (up to PLN 200,000)
  • Over 180 days: 1/180–540 of the maximum annual penalty

In practice, the tax office typically starts with a fixed penalty notice (PLN 1,000–2,000) and escalates to court proceedings in cases of persistent non-compliance.

Additional Tax Liability: 30% / 20% / 100%

30% of the VAT liability — when the tax office discovers an irregularity during an audit and the taxpayer has not corrected it beforehand:

  • Failure to use MPP (split payment mechanism) when mandatory
  • Incorrect VAT deduction
  • Non-payment of VAT at the reduced rate

20% of the liability — when the taxpayer self-corrects before an audit.

100% of the liability — in cases of fraud (fictitious invoices, VAT carousel schemes).

Late Payment Interest

Interest on VAT arrears stands at 13.5% per annum in 2026 (1.5× the NBP reference rate). It accrues daily from the date the VAT was due until the date of actual payment.

Example: VAT arrears of PLN 10,000 × 13.5% × 90 days / 365 = PLN 333 in interest for a 3-month delay.

Reduced interest: if you self-correct voluntarily (czynny żal — voluntary disclosure of the error) — 50% of the standard rate.

How to Appeal

  1. Audit decision — you have 14 days from the date of delivery to appeal to the director of the tax chamber
  2. Tax chamber decision — 30 days to file a complaint with the WSA (Voivodeship Administrative Court)
  3. WSA judgment — 30 days to file a cassation appeal with the NSA (Supreme Administrative Court)

Each step requires strong justification. Tip: voluntary disclosure (czynny żal) before an audit results in significantly lower penalties.

Frequently Asked Questions

What is czynny żal (voluntary disclosure) and is it worth it?
Czynny żal is a voluntary disclosure of an error BEFORE an audit begins — you pay the outstanding liability + interest + a reduced penalty (50%). It is nearly always worthwhile — it eliminates the 30% additional liability and removes criminal fiscal liability.
Is late payment interest tax-deductible?
No. Interest on tax arrears is NOT a tax-deductible expense — it is a fiscal penalty, not a business cost.
What if the tax office makes an error in its decision?
File an appeal with strong justification. Many decisions are reviewed and overturned in the taxpayer's favour. Consider engaging a licensed tax adviser (doradca podatkowy) — they carry mandatory professional liability insurance.
