The Business Cost Support is primarily confirmed on the basis of VAT returns submitted to the Tax Administration. If the company’s business is wholly or partly non-VAT sales, the company shall provide the sales data of the support period and the reference period in the application. In case a company does not apply the monthly VAT return procedure, it will have to verify its turnover in another way. If a company justifiably (for example, as evidenced by accounting) proves in another way than through the Tax Administration Register that a decline of more than 30% in turnover has occured, the State Treasury may also consider such account when determining Business cost Support.
