(1)The revenue laws of this state for the assessment, levying, and collection of taxes on real estate for county purposes, as modified in this section, shall be applicable for the purposes of this article, including the enforcement of penalties and forfeiture for delinquent taxes. However, in case of sale of any lot or parcel of land, or any interest therein, for delinquent irrigation district taxes or delinquent irrigation district and general taxes, when there are no bids therefor on any of the days of such tax sale, the same shall be struck off to the irrigation district in which such land is located for the amount of the taxes, interest, and costs thereon, and a certificate of sale shall be made out to said district therefor and delivered to its secretary, who shall file the same in the office of its board of directors and record the same in a book of public record to be kept by said board for such purpose, but no charge shall be made by the county treasurer for making such certificate, and in such case he shall make the entry “struck off to .............. irrigation district” on his records, as well as an entry showing the amount of the general irrigation district taxes and interest thereon, respectively, for which said lands were offered for sale, together with the cost attending such sale.
(2)No taxes assessed against any land so struck off to said district under the provisions of this section shall be payable until the same has been derived by the district from the sale or redemption of such lands. Such irrigation district or its assignee shall be entitled to a tax deed for said lands in the same manner and subject to the same equities as if a private purchaser at said tax sale, upon the payment to the county treasurer at the time of demanding said deed of such sum as the board of county commissioners of such county at any regular or special meeting may decide.
(3)In case the owner of said lot or parcel of land, or interest therein, desires to redeem the same at any time before said tax deed shall be issued, the same may be done in the same manner as is provided by law to be done, in case said lot or parcel of land, or interest therein, had been purchased by a bidder at said tax sale or had been struck off to the county. In such case the county treasurer shall forthwith issue a certificate of redemption therefor and notify the district secretary of said fact, who shall thereupon make a suitable transfer entry upon his record and return the certificate of sale to the county treasurer for cancellation.
(4)In case any person desires to obtain such certificate of purchase so issued to said irrigation district, the same may be done in the same manner as provided by law to be done in case said lot or parcel of land, or interest therein, had been purchased by a bidder at said tax sale or had been struck off to the county, upon payment to the county treasurer of the required amount in cash, or in cash together with warrants not in excess of the district general fund tax, or in cash and interest coupons or bonds not in excess of the irrigation district and redemption fund tax, or in cash and in warrants and bonds, respectively, not in excess of said respective funds.
(5)No action for possession of or to quiet title to land sold for taxes shall lie on behalf of the owner or claimant of the fee title as against the holder of the tax deed or his grantee claiming title or color of title thereunder in any case wherein the taxes or any part thereof for which said land was sold were levied for the maintenance, operating, and current expenses of an irrigation district or to pay the interest or principal of the bonds of such district, unless such action is brought within five years after the execution and delivery of the deed by the treasurer and the recording thereof, any law to the contrary notwithstanding. As a condition precedent to the right of such owner or claimant of the fee title to maintain his said suit for possession or to quiet title as against the person in possession under color of title, or as against the claimant of title to vacant and unoccupied land under a tax deed giving color of title to lands in an irrigation district, the plaintiff, at the time of filing his complaint, shall pay to the clerk of the court in which such proceedings are instituted, for the benefit of and to be paid to the person entitled thereto in case the plaintiff prevails in such suit, the amount of all taxes, interest, expenses, and penalties, including the amount of subsequent taxes paid on account of such sale which may have been paid thereunder, with interest on the whole of such sum at eight percent per annum.
(6)In any case in which the claimant has title or color of title to land in an irrigation district under a tax deed duly recorded, and brings his suit for possession of or to quiet title to such lands, the invalidity or alleged invalidity or insufficiency of the tax deed shall not be a sufficient defense after the expiration of five years from and after the execution, delivery, and record of said tax deed, nor, if such defense is pleaded prior to the expiration of said five years, shall the invalidity or insufficiency of the tax deed be considered by the court as a defense, unless defendant shall first deposit with the clerk of the court in which said suit is brought, a sufficient amount to pay the taxes, interest, expenses, and penalties, including the amount of subsequent taxes and interest at eight percent per annum, paid on account of such tax sale, for the benefit of and to be paid to the person entitled thereto, when ascertained by the judgment in said suit.
