Even if none of these special conditions apply, investigate whether the market value determined by the assessor is higher than the true market value of your property. Local real estate agents or the county registrar of deeds should be able to provide recent sales of comparable or similar properties in your area. Once you have the information you need to protest your assessment, you will either be required to fill out a form or make an appointment with the assessment board. Be prepared to bring facts and figures. If your appeal fails, depending on your state you may appeal that decision to a special board of equalization, a board of appeals, a state court, or a special tax tribunal.
State laws vary as to how and when property is assessed and appeal procedures.
For specific information, consult your local government officials or your lawyer. This is a free service.
