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. Because Maryland runs an annual bracket, low-volume e-commerce and online sellers can go twelve months between returns — which is exactly how long a liability account can drift before anyone looks at it.
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.

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%. 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.
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.
