Frequently Asked Questions

Fill out the property record form, and submit it to our office for review. You may be contacted by a staff member from the Office of the City Assessor if there are questions concerning the information about your property.  If you have any questions, please do not hesitate to contact the Office of the City Assessor at (269) 329-4433 or by email at assessingdept@portagemi.gov.

Almost all of the information in the Assessor’s Office is public record. The amount paid in taxes is also public record and is available online. Access the Assessor’s tax lookup site and look up information by name, address or parcel number. Square footage and 2025 values are available. 2026 values will not be posted online until the roll has been reviewed and confirmed following the March Board of Review. Preliminary information is available at the Office of the City Assessor beginning February 2026.

The Assessor is responsible for estimating the value of your property, which determines your assessed valuation. The Assessor does not determine your property taxes. Instead, the assessed valuation determines the overall share of taxes you pay. Because your assessment affects your property taxes, it is important that your assessed value be accurate and fair. It is also important that you understand how the value of your property is estimated and what can cause property values to change.

To change your email address, you need to send a written request by fax 269-324-8073, email or regular mail to:
7900 S Westnedge Avenue
Portage, MI  49002

OR use the fillable form under the Property Tax Forms tab, named Address Change Form.

This will change the address for both assessments and taxes.  It will not, however, change the water billing address.  You must contact the Portage Treasury Office at (269) 329-4455 separately, unless using the online fillable form.
