Alabama Utility Sales Tax Exemption
Alabama provides manufacturers and industrial processors with a utility sales tax exemption that helps reduce the cost of electricity, natural gas, and water used in qualifying production activities. This exemption removes state utility gross receipts tax and utility service use tax on utilities that are directly used in manufacturing or processing operations. It is authorized under Alabama Code § 40-21-83 and §40-21-103.
Qualifying Uses
Utilities are exempt when used directly in the following industrial processes:
- Electricity used in electrolytic or electrothermal manufacturing or compounding processes
- Natural gas used as a raw material in the production of tangible personal property
- Water used at least 50% in manufacturing or industrial processing activities
The exemption does not apply to utility use for general building operations such as heating, lighting, or air conditioning, unless those uses are part of the qualifying process.
Utility Study Requirement
Alabama does not provide a general percentage-based utility study method for apportioning exempt and taxable utility usage when the same utility service is used for both qualifying and nonqualifying purposes. Under Alabama Admin. Code r. 810-6-5-.26, a utility provider may treat only the taxable portion of utility service as taxable when its books separately show the taxable and nontaxable utility services furnished. If those records are not separately maintained, the provider must pay tax on the total gross receipts from the utility services furnished.
For mixed-use accounts, the regulation states that this separate treatment requires separate meters for taxable and nontaxable services, and that estimates are not acceptable. As a result, a utility study can be useful for identifying qualifying equipment, documenting the exempt use, supporting the Form STE-3 exemption application, and determining whether separate metering is needed. However, a study based on estimated usage should not be presented as a substitute for separate metering where Alabama requires taxable and nontaxable utility services to be separately shown.
For water, Alabama provides a specific rule for industrial-process use. Water is excluded from taxable “domestic water” when more than 50% of the total water purchased is used in qualifying industrial processing. If more than 50% is used for human consumption, the total receipts are taxable. This water rule is distinct from a general estimated-usage study and should be evaluated separately from electricity or natural gas usage.
Filing Requirements
To claim the exemption, eligible businesses must complete and submit Alabama Form STE-3 (State Utility Tax Certificate of Exemption) to their utility provider. This form certifies that the utility usage qualifies under state law. The utility company, upon receiving the certificate, will stop charging utility gross receipts and service use tax on the qualifying portion.
The utility provider is generally held responsible for collecting tax unless a valid exemption certificate is received. A properly completed STE-3 form protects the provider from liability if the state later determines the exemption was incorrectly applied.
If a business has paid tax on utility usage that qualifies for exemption, it may request a refund for up to three years from the date the tax was paid. Refunds may be claimed either through the utility provider or directly from the Alabama Department of Revenue, depending on the circumstances and timing.
