Valuation Appeal
As a property owner, you have rights. If you feel your 2026 value is incorrect, please follow the link listed that will take you to our Beacon Website. Review your property details and make note of any discrepancies. In the upper left hand corner, there is the word "MAP", click on it and along the left hand layer list there is the option to select Residential Sales, please check it and then also select Sioux City Residential Sales underneath it. This will show you all of the sales in your area that have influenced your value. If at that time, you still feel your value is incorrect you may file an appeal using the online appeal form. Petitions are available only during appeal dates (starting April 2). Your petition will be reviewed by an Appraiser and if there are any questions, they will reach out to you.
The normal appeal period is from April 2 to April 30. An informal agreement may be able to be reached with the Assessor's office between April 2 to April 25.
Petition: Please follow the link below to the online appeal program.
Online Appeal Program Link: Beacon Website
To assist in the process, the Sioux City Assessor has put into action an online appeal program. Property owners will have to search for their property on the Beacon Website first before an appeal can be started (this is a pre-populated form). Click on the link, enter the property you wish to appeal and navigate towards the bottom of the property information. Right above the photo, there should be a blue box labeled "Board of Review Petition". Click on that button and follow the directions to fill out your appeal.
Instructions and petitions will be available in office April 2nd through April 30 only. Office hours are 8:00 - 4:30.
