Homestead Applications are taken throughout the year. However, the deadline for the exemption to apply for the current year's taxes is April 1 of that year. For example, for the exemption to apply for 2022, the deadline is April 1, 2022. If you file April 2 or later, the exemption will be applied to the following year. In this case, 2023. The only exception is for the 100% disabled veteran exemption.
