    Notice of Delinquent Taxes:

    The law requires that a notice be sent to property owners who have outstanding taxes as of February 1.

Iowa law also requires that a notice of the annual tax sale shall be mailed not later than May 1 to the person in whose name the parcel subject to sale is taxed. In compliance with this law, a Delinquent Tax Statement and Tax Sale Notice is mailed in April to provide proper notice of the pending tax sale.
