These deductions shall be made within the limit of the net tax liability provided for in the aforementioned Law and in the corresponding General State Budget Laws.For these purposes, the net tax liability shall be understood to be that resulting from reducing the gross tax liability by the deductions and allowances provided for in Chapters II and III of Title VI of the LIS (box ).
