Iowa Code Title X. Financial Resources [Chs. 421-454] § 441.46. Assessment date

1. The assessment date of January 1 is the first date of an assessment year period which constitutes a calendar year commencing January 1 and ending December 31. All property tax statutes providing for tax exemptions or credits and requiring that a claim be filed, shall be construed to require the claims to be filed by July 1 of the assessment year. If no claim is required to be filed to procure an exemption or credit, the status of the property as exempt or taxable on July 1 of the fiscal year which commences during the assessment year determines its eligibility for exemption or credit. Any statute requiring proration of property taxes for any purpose shall be for the fiscal year, and the proration shall be based on the status of the property during the fiscal year.

2. The assessment date is January 1 for taxes for the fiscal year which commences six months after the assessment date and which become delinquent during the fiscal year commencing eighteen months after the assessment date.
