Dear Property Owner and/or Property Representative,

Instead of mailing the RP-420-a/b-Renewal Forms, i.e., I-Organization Purpose & II-Property Use, that you are required to complete annually, we are asking you to voluntarily file your I-Organization Purpose & II-Property Use RP-420-a/b-Renewal Forms for each applicable parcel you own securely online after April 10th.

Failure to file each renewal form for each parcel may result in the loss of your RP-420-a/b Property Tax Exemption.
You are strongly encouraged to complete both forms online annually before September 15th.

NOTE: If you prefer not to file online, we can email you the fillable forms. Please send your request, and upon completion of your forms, please submit to AssessmentSupport@yonkersny.gov.
