Construction & Trades Bookkeeping in Maryland

The question that decides Maryland sales tax for construction & 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 & trades file will look for them.

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. Businesses routinely register for one and forget the other, then discover the gap when a notice arrives.

The Maryland statewide base rate is 6%. Local rates stack on top and are generally sourced to the delivery address, so the effective rate varies within the state. Getting sourcing right is what keeps the liability account matching what you actually collected.
