Indiana is the most manufacturing-intensive state in the country by share of GDP — autos and auto parts, the RV cluster around Elkhart, Northwest Indiana steel, Eli Lilly and pharma, and machinery. Manufacturing books don’t run on periods; they run on cost. Real manufacturing accounting needs job and work-order costing (material, labor, machine time, and overhead applied to each run), standard-vs-actual costing with variance analysis, and inventory and WIP tracked across raw, work-in-process, and finished goods — often across multiple plants.
Indiana’s tax layer is mostly clean — a flat 2.95% income tax (2026) and a single 7% sales tax with no local add-ons — but two things are genuinely Indiana. First, the business tangible personal property tax exemption jumped to $2,000,000 for 2026 (up from $80,000): if your total business personal property in a county costs under $2M on the assessment date it is exempt — but the exemption still has to be declared on Form 102 or 103, and the PPOP-IN online portal was discontinued for 2026. Second, every plant’s payroll carries the county local income tax (LIT) of each employee’s county of residence, set on January 1 and withheld through Form WH-4.
TechBrot sets up job and standard costing, inventory/WIP, and the asset detail behind the $2M exemption in your own QuickBooks file, keeps it accurate monthly, and turns it into per-job and per-line profit you can act on. We track the asset detail and prepare or coordinate the Form 102/103 filing posture — we keep the books CPA- and assessor-ready; we do not file the county return as agent. We deliver the books; your CPA files. Independent firm — not affiliated with Intuit Inc. Confirm personal-property detail with the Indiana DLGF.
