Construction & Trades Bookkeeping in Maryland

The question that decides Maryland 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. Maryland taxes certain digital products and SaaS, which catches software and subscription businesses out. We code parts and labor separately on every job so the treatment is deliberate.

Contractor and trade licensing in Maryland is administered separately from tax registration, and the entity itself is registered with the Maryland State Department of Assessments and Taxation. 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 Maryland bites hardest is the overlap: a licence renewal can be held up by a delinquent account with the Comptroller of Maryland, so a sales tax balance nobody reconciled becomes a licensing problem rather than just a tax one.

Employer registration in Maryland runs through the Maryland Department of Labor, a different agency from the Comptroller of Maryland 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 Maryland Department of Labor 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 Maryland statewide base rate is 6%. That sits mid-table nationally, with local rates layered on top and sourced to the delivery address rather than to your own location. Sourcing is where this is won or lost, and with economic nexus set at $100,000 in sales or 200 transactions, it becomes your problem the moment that threshold is crossed.
