Maine taxes through the Maine Revenue Services at a 5.5% statewide base rate, with local rates stacking on top and economic nexus for remote sellers at $100,000 in sales. 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 Maine Department of Labor, and the entity is registered with the Maine Secretary of State. No local sales tax, but lodging and prepared food carry higher dedicated rates.

Sales tax nexus in Maine
Economic nexus in Maine is $100,000 in sales. 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 Maine Revenue Services and begin collecting. We track your Maine sales against it and tell you before you cross, not after.
Marketplace sales vs. your own channels in Maine
Marketplace facilitator rules mean large platforms generally collect and remit Maine 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 Maine Revenue Services return match reality.
Maine rates and sourcing
The Maine statewide base rate is 5.5%. 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 Maine
Maine assigns filing frequency by liability — monthly, quarterly, or annually by liability. Because Maine 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.
