Tax Division Subpages

  1. Exemptions

    Homestead, school tax and disability exemptions may be filed all year long, but to qualify for the current year exemption, you must occupy the property by Jan. 1 and apply by April 1. That is the absolute deadline for filing—all forms filed after April 1 will be processed for the following year. Even if you qualify for any or all of the exemptions, you will not receive the exemptions for that year if you do not meet the deadline. Applications postmarked by the due date are accepted.
