- Since 2012, taxpayers are legally required to report to the Tax Administration if they have paid too little VAT in the past five years.
- The obligation is known as the supplementary obligation and was introduced to prevent taxpayers from remaining unpunished after discovering they had paid too little tax.
- As of January 1, 2025, the supplementary obligation has been further tightened.
- The new regulation requires that the taxpayer supplements within 8 weeks of discovery or, if earlier, before he knows or reasonably should suspect that the Tax Administration will discover the error.
- Failure to comply with the supplementary obligation is considered an offense for which a penalty can be imposed.
- If the Tax Administration can demonstrate that the taxpayer intentionally or through gross negligence failed to supplement, the penalty can amount to 100% of the tax amount that would remain unpaid due to non-compliance with the supplementary obligation.
- It is advisable to record internally when and why an error was discovered and to ensure that a supplement is submitted as soon as possible, but in any case within 8 weeks.
