Filing Requirement

All companies assessed by the State Assessed Property Bureau are required to electronically file an annual property tax return on or
before *the last day of February of the tax year. All real and personal property used in the conduct of business in the following specialized
industries is required to be reported:

• railroad;
• telecommunications;
• pipeline;
• public utility;
• airline;
• electric generating plants, whether or not owned by a public utility, if all or part of the electricity is generated for ultimate sale to the public;

• machinery, equipment and other personal property of all resident and non resident persons customarily engaged in construction that involves the use, during a tax year, of the machinery, equipment and other personal property in more than one county.

*The statutory deadline for filing annual property tax returns with the State Assessed Property Bureau is the last day of February of the tax year. If the last day for filing the return falls on Saturday, Sunday, or a legal state or national holiday, filing is timely if performed on the next workday.

Extension of Time to File
If you are unable to file by the reporting deadline, an Extension of Time to File must be requested in the SAEF Portal on or before the last day of February of the tax year to avoid a late filing penalty. Extensions granted shall be for a period of not more than thirty (30) days.
