It should also be clarified that the taxpayer - heir cannot deduct the inherited taken over thermal modernization relief in the annual own return submitted for the year in which the testator incurred the reported expenses entitling him to this relief. Pursuant to Art. ยง of the Tax Ordinance, if, among others, an annual tax declaration has not been submitted , the tax authority is obliged to issue a decision on the scope of liability or rights of the heirs. In this decision, it determines the amount of the liability or overpayment to be settled. Consequently, only after delivery of this decision, the heir may include in his/her tax return for the tax year following the year covered by the tax office's decision the part of the relief not deducted by the testator under the principles of Art.
