2026 Grievance Instructions

CONTESTING YOUR ASSESSMENT – 2026 GRIEVANCE INSTRUCTIONS

 GRIEVANCE APPLICATIONS WILL NOT BE ACCEPTED PRIOR TO JUNE 1, 2026

 Be sure to check your assessment and full market value on the 2026 tentative assessment roll which will be available for review as of June 1, 2026. Only the assessment on the current tentative assessment roll can be grieved - you cannot grieve assessments from prior years. There is no cost to grieve an assessment, and it does not require you to hire an attorney or property tax grievance consulting company.

If you feel your assessment/full market value is higher that your house is worth, you can submit a grievance application along with supporting documentation to the Town of Yorktown, Assessment Office.  Supporting documentation includes properties that have sold within 1 year of July 1, 2025 (valuation date) within your market area (neighborhood and school district) that are similar to your home. You can conduct research on public websites such as realtor.com to find sales in your area, or you can have a comparative market analysis done by a Realtor, or a private appraisal done by a Licensed Real Estate Appraiser. If you already have a recent appraisal, you can submit the appraisal as supporting documentation. If you recently purchased your home, you can submit the appraisal done by your mortgage company and/or your contract of sale.

Your complete application and supporting documentation must be received by the Assessment Office by 8:00pm on June 16, 2026.
Post marked by this date will not be accepted.

Grievance applications can be submitted in person, by mail, FedEx, UPS, or placed in the secure drop box located at the rear entrance of Yorktown Town Hall. 
NOTE: E-Mail applications will not be accepted.
