According to the information of the General Financial Directorate published on the website of the Czech Financial Administration, the following situations are considered a significant breach and also the fulfilment of only one criterion will be enough to determine a breach: the VAT payer violates statutory obligations, resulting in an assessment or additional assessment of tax in an amount exceeding CZK 500.000 (approximately euro 20,000 euro) without accrued interest and fees; the VAT payer engages in “fraudulent” transactions and the tax administrator issues a security payment order that is not paid within the stated deadline; or over no fewer than three successive calendar months, the VAT payer has a cumulative VAT underpayment of no less than CZK 10 million (approximately 400.000 euro) without accrued interest and fees.
