Rate Structure
State base rate: 6%
Local option: Cities and counties in Maryland can add local rates on top, bringing combined rates to 6% – 6%.
Sourcing: Most states use destination-based sourcing (rate is based on where the customer receives the product). Verify with Maryland Department of Revenue for edge cases.
Economic Nexus
Out-of-state sellers must register and collect Maryland sales tax once they exceed:
- $100,000 in annual sales to Maryland customers
- OR 200 transactions per year
In-state sellers (physical presence) must register from day one — no threshold applies.
Effective enforcement began in 2018 following the South Dakota v. Wayfair decision.
Marketplace Facilitator Law
Yes — Maryland has a marketplace facilitator law. Marketplaces like Amazon, Etsy, Walmart Marketplace, and eBay collect and remit sales tax on your behalf. Sales made through those marketplaces typically don't count toward your economic nexus threshold in Maryland. Sales made through your own website or invoicing do count.
Registration Process
- 1
Confirm you have nexus
Use the Nexus Checker to confirm you've crossed the threshold. Physical presence triggers registration immediately.
- 2
Register with the Maryland Department of Revenue
Typically 30-60 days after crossing threshold. Free registration (no fee) in most states. You'll get a sales tax permit / seller's permit.
- 3
Collect sales tax on taxable transactions
Configure your ecommerce platform (Shopify, Amazon, WooCommerce) to charge the correct destination rate. Most platforms have built-in tax logic.
- 4
File returns on schedule
Filing frequency (monthly/quarterly/annual) is set by the state based on your volume — typically monthly for high-volume sellers.
Multi-state seller? Consider a sales-tax service (TaxJar, Avalara) or a specialist CPA once you're registered in 5+ states — the return-filing workload compounds fast.
