Steps to register for sales tax in Maryland

Step 1: Determine if you have nexus (physical presence, employees, or over the state's economic nexus threshold — usually $100k in sales or 200 transactions)
Step 2: Register through the state's Department of Revenue online portal (free in most states)
Step 3: Get a sales tax permit / seller's permit number

If your setup is simple, filing yourself through the Maryland portal is straightforward; if it's not (foreign qualification, complex ownership, non-US members), the extra service cost is often justified.
