The law requires an annual application by April 30 for some types of exemptions, including property exempted from Taxation by Agreement (Property Tax Abatement), Historical and Archeological Sites, Miscellaneous Exemption, Low Income Housing Exemption, and exemption of Freeport Goods.

Cemeteries, charitable organizations, youth development organizations, religious organizations, non-profit private schools, and exemption of Pollution control property approved by the Texas Commission on Environment Quality (TCEQ) do not have to reapply for the exemption each year once the property tax exemption is granted, unless by written notice, the Chief Appraiser requests the property owner to file a new application. However, if their exempt property changes ownership or if their qualifications for exemption change, they must reapply.
