Maryland taxes through the Comptroller of Maryland at a 6% statewide base rate, with local rates stacking on top and economic nexus for remote sellers at $100,000 in sales or 200 transactions. Filing runs monthly, quarterly, or annually by liability. For e-commerce & online sellers, that combination is what decides how much of your month-end is bookkeeping and how much is compliance.
Employer registration runs through the Maryland Department of Labor, and the entity is registered with the Maryland State Department of Assessments and Taxation. No local sales tax. Maryland taxes certain digital products and SaaS, which catches software and subscription businesses out.

Sales tax nexus in Maryland
Economic nexus in Maryland is $100,000 in sales or 200 transactions. For e-commerce & online sellers, that threshold is the one to watch, because it is reached by selling into the state — no office, no staff, no physical presence required. Once you cross it you are expected to register with the Comptroller of Maryland and begin collecting. We track your Maryland sales against it and tell you before you cross, not after.
Marketplace sales vs. your own channels in Maryland
Marketplace facilitator rules mean large platforms generally collect and remit Maryland tax on sales made through them. Your own site, wholesale, and direct sales are a different matter — those remain yours to collect and report. Keeping the two streams separate in the books is what makes the Comptroller of Maryland return match reality.
Maryland rates and sourcing
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.
Filing cadence in Maryland
Maryland assigns filing frequency by liability — monthly, quarterly, or annually by liability. Because Maryland includes an annual bracket, a low-volume seller here can go a full year between filings, which is exactly when a liability account drifts unnoticed. We reconcile it monthly regardless of when the return is due.
We keep the books. You run the business.
Categorization, reconciliation, month-end close, and clean financial statements — with nothing left for you to chase.
