How Small Indiana Manufacturers Are Recovering Big on Sales Tax
Last Updated on June 16, 2025
Even seasoned manufacturers in Indiana often overpay sales tax—especially on fixed assets and everyday expense purchases. With complex rules and gray areas around items like software, R&D, and repair parts, many businesses err on the side of caution and simply pay the tax.
That adds up.
While medium and large manufacturers are frequent candidates for sales tax recovery, smaller manufacturers like machine shops can benefit just as much. Even with a steady and predictable spend, there’s often hidden overpayment.
Take this Indiana machine shop, for example—operating in a 25,000 sq. ft. facility. Here’s what their refund uncovered:

Indiana: A Prime State for Sales & Use Tax Refunds
If you’re a manufacturer in Indiana, you’re in one of the best states for recovering overpaid sales and use tax. A refund review (also known as a reverse audit or overpayment review) can boost cash flow, uncover savings, and help you stop overpaying tax going forward. Here’s what you need to know:
- 3-Year Lookback — Indiana’s statute runs by calendar year. You can currently recover tax paid from January 2022 onward.
- 90-Day Deadline — The state must issue a decision on your refund claim within 90 days or start paying interest.
- Utility Refunds — A predominant use study is required to claim refunds on manufacturing utilities.
- No Audit Risk — A refund review won’t automatically trigger a sales tax audit.
If you’re paying sales or use tax on purchases tied to your operations, a refund review isn’t just a smart move—it’s a peace-of-mind check to ensure you’re not overpaying. Every dollar matters, especially the ones you’re owed.
