Construction & Trades Bookkeeping in District of Columbia

The question that decides District of Columbia 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. Several categories carry their own rates above the general rate, including restaurant meals and commercial parking. We code parts and labor separately on every job so the treatment is deliberate.

Contractor and trade licensing in District of Columbia is administered separately from tax registration, and the entity itself is registered with the DC Department of Licensing and Consumer Protection. 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 District of Columbia runs through the DC Department of Employment Services, a different agency from the DC Office of Tax and Revenue 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 District of Columbia 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.
