In 1989, Texas voters approved a constitutional amendment giving local taxing jurisdictions the option to exercise or not exercise their authority to tax specific personal property known as Freeport goods.
The Freeport exemption exempts certain types of tangible personal property (i.e., inventory) from ad valorem (property) taxation provided the property is:
Because oil, natural gas, and other petroleum products are not considered Freeport goods, they are not eligible for the exemption and therefore remain taxable. Even when goods are sold to an in-state purchaser rather than shipped out of the state, they may qualify for the Freeport exemption; however, the property must qualify under the above requirements as Freeport property and must be transported out of the state within 175 days after it was first acquired in or imported into the state.
Harlingen and the Harlingen CISD have eliminated the tax on interstate inventory and established a Freeport. The Freeport exempts from tax inventory and materials-in-process manufactured locally and shipped out of Texas within 175 days.
