- If you have made an incorrect or incomplete VAT return in the current year or in the past five years, you are required to correct it by submitting a supplementary return
- A supplementary VAT return is a correction submitted when it is discovered that a mistake was made in a previously filed VAT return, or something was forgotten
- For small amounts (up to €1,000) the correction can be made in the next VAT return, otherwise a separate supplementary return is required
- The deadline for submitting supplementary VAT returns is now within 8 weeks of discovery, instead of ‘as soon as possible’
- Failure to submit the correction on time may result in a penalty of up to 100% of the VAT owed
