The Belgian tax authorities are still actively checking Dutch webshops to see whether webshops not established in Belgium have already exceeded the threshold of € 35,000 in the past. To this end, information about sellers was requested from Bol.com, among others. Dutch webshops still receive additional assessments from Belgium with a substantial amount of fines (even up to 200% (!) of the VAT amount). By registering voluntarily, fines can be limited. The VAT amount due in Belgium must simply be paid, but at the same time the VAT wrongly paid in the Netherlands can be reclaimed. Please note: Belgium deducts seven years, while the Dutch Tax and Customs Administration can ‘only’ refund five years on the basis of the formal term.
