  • Sales tax line: 6.00% state rate. Most services rendered in Maryland are exempt from sales tax — but materials, parts, and tangible goods are not. State 6%; uniform statewide. No local sales tax.
  • Late-fee cap: Maryland statute Md. Com. Law §12-103 caps interest on unpaid invoices at 1.5% per month. Spell out the rate in writing on every invoice and in your contract — courts won't enforce undisclosed fees.
