In its latest judgment, the European Court of Justice (ECJ) comments on the legal case Petroma Transports and others regarding the question of VAT deduction following an invoice correction. According to the ECJ’s statements, invoice corrections have to be transmitted to the responsible tax office before decisions on denying VAT deduction are being made. It could be interpreted that VAT deduction with retroactive effect should be pos-sible. Therefore, entrepreneurs are forced to take action by having invoices corrected properly and quickly as well as transmitting the corrected invoices to the tax authorities in time.
