The toll receipts are qualified as invoices for tax purposes, as was explained by the Tax Authorities in a guideline published on its website. The reason for the clarification of the Tax Authorities were the questions raised by some companies on the tax validity of receipts automatically issued by machines like the tolls. The Government had already set out in the State budget for this year that the mandatory issuance of invoices could be fulfilled by issuing documents or the registration of transactions in the case of the supply of transport services, parking, tolls and admissions to shows, when a transport ticket, a show ticket or other bearer documents which may prove the payment is issued. However some companies have raised doubts about the tax validity of receipts issued automatically by machines such as tolls, which is the reason why the Tax Authority felt the need to clarify this matter.
