How Utility Studies Help Manufacturers Qualify for Sales Tax Exemptions

It’s no secret many states offer sales tax exemptions for items used in the manufacturing process: exemptions for raw materials, chemicals, computers, industrial fixtures, equipment, machinery, even certain services. However, an interesting newcomer just joined this space, as utility purchases may also qualify for exemptions.
In most states, utilities are indeed subject to sales tax. Utility companies calculate sales tax based on usage, and businesses pay these taxes during each billing cycle. But the good news is that manufacturers can potentially reduce or even eliminate this tax by obtaining a utility sales tax exemption certificate.
This certificate instructs the utility company to exempt a portion of the sales taxes assessed on your utility bill. To qualify, you must demonstrate you use utilities for qualifying exempt activities. Each state maintains its own list of such activities, but generally, businesses that use utilities for producing, manufacturing, or processing tangible personal property can obtain these exemption certificates.
Remember, understanding your state’s specific regulations is crucial to taking advantage of these exemptions and potentially saving your company significant costs.
Make sure you follow the application process: Like other sales tax exemptions, you must document the exempt percentage and submit an exemption certificate for utility purchases.
Submit one exemption certificate for each utility provider. For instance, if you use water, natural gas, and electricity in your manufacturing process, you’ll need to submit three separate exemption certificates based on each’s exemption percentage.
Each state has its own application process. For example, Businesses in Missouri can use Form 149 to certify the qualification for a utility exemption, which is the same form used for other sales tax exemptions. In Kansas, however, businesses request exemptions using an application specific to utilities, known as Form ST-28B.
When completing the exemption application, states typically ask for the following details:
To determine your energy usage, it’s crucial that you calculate the percentage of utilities used for exempt activities, so seek assistance if needed to accurately determine this percentage.
Remember, understanding your state’s specific regulations is essential to taking advantage of these exemptions and potentially saving your company significant costs.
A utility study is commonly requested by manufacturers to assess the proportion of utilities used in their manufacturing processes. In certain states, these studies are mandatory. If you do not properly document and have support for the exemption, you run the risk of the state denying the exemption and requiring repayment of tax for unqualified exemptions previously taken.
