Construction & Trades Bookkeeping in Indiana

The question that decides Indiana sales tax for construction and trades is how labor, materials, and installation are treated — states split on whether the contractor is the end consumer of materials or a reseller, and whether installation labor is taxable. No local sales tax, which makes Indiana unusually simple to calculate. We code parts and labor separately on every job so the treatment is deliberate.

Contractor and trade licensing in Indiana is administered separately from tax registration, and the entity itself is registered with the Indiana Secretary of State. Licensing is not bookkeeping, but it touches the books — license and permit costs, bonding, and insurance all need consistent treatment, and lenders reviewing a construction and trades file will look for them. Where Indiana bites hardest is the overlap: a licence renewal can be held up by a delinquent account with the Indiana Department of Revenue, so a sales tax balance nobody reconciled becomes a licensing problem rather than just a tax one.

Employer registration in Indiana runs through the Indiana Department of Workforce Development, a different agency from the Indiana Department of Revenue that handles your sales tax — a separate account number, a separate login, and separate deadlines. Standing with one says nothing about standing with the other, and for construction and trades the first sign of a gap is usually a notice rather than a reminder. Your unemployment insurance rate is set by the Indiana Department of Workforce Development from your own claims history, which means it is a cost you can actually influence — and one that quietly changes each year while the payroll journal entry stays the way somebody set it up.

The Indiana statewide base rate is 7%. That is among the highest state rates in the country before a single local rate is added, which makes a miscoded category expensive per transaction rather than merely untidy. Sourcing is where this is won or lost, and with economic nexus set at $100,000 in sales, it becomes your problem the moment that threshold is crossed.
