Whenever it shall be necessary to compute the indebtedness of a county or of any of its institutions or agencies, for bonding or other indebtedness purposes, delinquent taxes and taxes levied for the purposes set forth in the budget of the county shall not be considered an asset, but shall be deemed for such purposes to have been already pledged and expended for the purposes, objects, and items set forth in the budget; provided however, that all taxes levied for the payment and redemption of bonds, warrants, or other public debts, shall be deemed a competent and sufficient asset to be considered in the calculation of any constitutional or statutory limitation.
