Discover how to unlock hidden tax savings, recover overpaid sales tax and optimize manufacturing efficiency.
Understanding the Predominant Use Threshold
The value of a Predominant Use Study lies in its ability to demonstrate that a majority of resources such as utilities, machinery or supplies are used in exempt manufacturing or processing activities. When this threshold, typically over 50% of usage, is met, businesses may qualify for an exemption from sales tax and recover sales tax paid in prior years.
When a study is properly performed, often using a detailed utility usage study, manufacturers can recapture sales tax paid on electricity, natural gas and water to reduce future tax liability. This includes identifying usage measured by kilowatt hour from utility bills issued by utility companies.
By identifying and documenting predominant use, businesses can:
- Recover thousands to millions in sales tax refunds, including utility sales tax exemptions on gas and water
- Reduce future sales tax liability on utilities, equipment and new acquisitions
- Free up cash previously tied up in overpaid sales tax for reinvestment in operations, technology or expansion projects
Ultimately, Predominant Use Studies reward operational efficiency by aligning tax savings with how resources are used in production.
Which Expenses and Activities Qualify for Sales Tax Recovery
A Predominant Use Study analyzes which expenses and activities meet exemption criteria under state law. While states require specific documentation standards, qualifying items commonly include:
- Utilities such as electricity, natural gas and water used in manufacturing or processing; usage is documented through utility bills and kilowatt-hour analysis to support an exemption from sales tax
- Machinery and equipment, including each qualifying piece of equipment primarily used in exempt activities, as well as new purchases or facility expansions
- Supplies directly associated with manufacturing, processing or agricultural operations
Accurate documentation allows businesses to look back for several years to recover sales tax paid while ensuring future utility and equipment purchases qualify for ongoing exemptions.

How to Claim Sales Tax Exemptions with a Predominant Use Study
Capturing value through a Predominant Use Study requires a structured and defensible process, often involving licensed engineering expertise to meet state requirements.
This approach ensures businesses recapture historical overpayments while securing long-term tax savings on high-impact costs like utilities and equipment. Ayming’s Predominant Use Study process involves:
Evaluate eligibility and identify potential savings related to utilities, equipment, new facilities or major capital investments
Gather historical and current utility bills, production data and equipment usage from utility companies and internal systems
Perform detailed utility studies to calculate predominant use percentages by kilowatt hour or operational usage
Prepare reports to support sales tax refunds, establish a utility sales tax exemption and reduce future liabilities
Implement processes to maintain exemptions and support future reviews as operations evolve
Additional Benefits of Predominant Use Studies
Beyond recovering past taxes, Predominant Use Studies deliver lasting strategic value:
- Recover overpaid sales tax on utilities and equipment as it is often one of the largest overlooked savings opportunities
- Lower future tax liability by establishing exemptions for electricity, natural gas, water, machinery and new equipment purchases
- Improve cash flow by unlocking funds previously paid in error, supporting reinvestment in growth initiatives
- Ensure compliance through detailed documentation that supports complex reviews
- Align operational efficiency with tax strategy, rewarding manufacturers that maximize resource use in qualified exempt production activities
By accurately documenting how utilities and equipment are used, businesses transform routine operating costs into measurable, defensible financial advantages.
