Section 75.61 - Actions related to tax certificates(1) ONE-YEAR LIMITATION. Every action enumerated in s. 75.57, 1955 stats., and s. 66.0731, and every action or proceeding to set aside any inclusion of land in a tax certificate for the nonpayment of taxes, or to cancel any tax certificate, or to restrain the issuing of any tax certificate, or tax deed, for any error or defect going to the validity of the assessment, and affecting the groundwork of such tax, or on account of any void or defective special assessment, shall be commenced within one year from the date of issuance of the tax certificate under s. 74.57, and not thereafter. In every action brought to set aside any such inclusion of land in a tax certificate, or to cancel any tax certificate, or to restrain the issuing of any tax deed upon any ground whatever not going to the validity of the assessment and affecting the groundwork of such tax, special assessment, special charge or special tax, the plaintiff, if he or she shows himself or herself otherwise entitled to judgment, shall, before the entry thereof within a reasonable time to be fixed by the court, pay into the court for the county or city authorized to act under s. 74.87 holding the tax certificate the amount for which such land is delinquent, with interest on all such amounts at the rate of 8 percent per year from the times of payment until the money is paid into court; and in default of such payment within the time so fixed the defendant shall have judgment in the action. This provision as to the payment into court to be made by the plaintiff shall apply to all actions brought to cancel any tax deed, or to remove the cloud upon any title created by any tax certificate or tax deed where the action impeaches the tax deed or tax certificate upon any grounds whatever not affecting the groundwork of the tax for the nonpayment of which such deed or tax certificate was issued.(2) TAX CERTIFICATES OF COUNTY, DISCOUNT ON. Whenever the county holds tax certificates upon real estate and the owner of said real estate or any person, firm, association, corporation or limited liability company holding a valid lien thereon shall claim the assessment of said real estate to be greater than the value that can ordinarily be obtained therefor at private sale, the respective town board, village board or city council where said real estate is situated may take proof under oath of the value of said real estate and make a finding thereon. Upon the filing of said finding with the county treasurer, the treasurer shall accept from said owner or lienholder the proper proportional tax on said real estate based upon the value so found, together with the proper charges, as in the case of redemption of tax certificates, shall cancel said tax certificate as it relates to that real estate, and shall give to said owner or lienholder a receipt for said tax. The difference between the tax as returned and the amount of such proportional tax, exclusive of charges, received by the county as a result of the compromise shall be charged to the town, village or city which returned the same and may be included by the county as a special charge in the next tax levy against such town, city or village.1979 c. 110; 1987 a. 378; 1993 a. 112; 1999 a. 150 s. 672.
