The Board has 3 months from the date you submit your application to act on it.
If your application is granted, your property's taxable assessment will be adjusted accordingly and you will be mailed a certificate showing the adjustment to your assessment. If you choose to pay the 3rd quarter tax bill, any adjustment will be reflected on the balance that's due in the 4th quarter. If you choose to pay the 3rd and 4th quarters, any adjustment will be refunded to you via check by the Treasurer's office. Filing an abatement application does not stay the collection of your taxes. And remember, abatement applications are usually due on the same day as the 3rd quarter payment. If your plan is to wait until the Board of Assessors decides on your application before paying, you will end up incurring interest and late fees on your bill that must be paid even if an abatement is granted.
If your application is denied, no adjustment will be made to your assessment and you will be mailed a certificate stating the reason the Board denied your application.
