Online Real Estate Appeal Application - Residential Properties Only

The deadline for submitting online appeals is April 1, 2024 at 4:30 p.m. (EDT). Administrative appeals will not be accepted after this date. 

This online application is for residential properties only (single family, townhouse, duplex, and condominium).

Commercial real estate appeals require an application that is available on the Tax Forms page.

This is not a Board of Equalization (BOE) appeal application. Please see the BOE site for more information on filing an appeal with the Board of Equalization.

Appeals may result in assessed values being affirmed (no change) or adjusted upward or downward to establish a fair and equitable assessment of your property.

You will be provided with written notification of the results of the review of your appeal by mail.

More information is available about real estate assessments and assessment appeals.

This appeal application should take about 15 minutes to complete if you have done your research in advance. To avoid the application timing out, you are strongly encouraged to have all the information you plan to enter available before you begin the process. If your appeal is submitted correctly, you will get an email confirmation. If not received, you may need to resubmit.

Research for sales and comparable properties is available at the Real Estate Assessment Information Site. This site allows searches by street name (no street number required) or by tax map number (partial map numbers are accepted i.e., the numbers "0584 20" in the full map number of "0584 20 0045"), as well as providing a link to sales in your assessment neighborhood.

The online application is set to timeout after one hour.

If you prefer to complete a hardcopy form, you may download an appeal application from the Tax Forms page or you may contact us to have a form mailed to you.

For accessibility standards and technologies supported, please see our standards page.
