Explanation of Business Property Tax Credit

Business Property Tax Credit Form


Qualifying persons may file for rent reimbursement from the State of Iowa after January 1st for a portion of rent paid in the 2019 calendar year. Not all renters will qualify for this program. The reimbursement is based on a portion of the rent going to pay property taxes on the property.

If you filed last year you should receive a pre-printed form for 2019 in the mail directly from the State of Iowa. You should use that form to hasten the processing of your claim.

If you do not receive a form directly from the State of Iowa by mail, you may click here to obtain forms from the IDRF Forms page.

Real property is revalued every two years. The effective date of the assessment is the first of January of the current year. The Assessor determines either a full or partial value for new construction and improvements depending upon their state of completion on January 1st.

The Assessor is concerned with value, not taxes. Taxing jurisdictions such as schools, cities and county, adopt budgets after public hearings. This determines the tax levy, which is the rate of taxation required to raise the money budgeted.

The taxes you pay are proportional to the value of your property compared to the total value of property in your taxing district.
