  • A business has “nexus” (significant presence in the state) such as a retail store, office or warehouse where products are produced, stored and/or delivered
  • Occasionally selling items at craft shows, fairs, seminars, conventions, etc in Maryland

What products and services are taxable in Maryland?

Physical products

There are a few exceptions, but almost all physical products are taxable when sold at retail in Maryland.  Common examples include:

  • General merchandise like furniture, appliances, and clothing
  • Titled or registered items like vehicles

Some foods, medicine and medical equipment, security services and sales of machinery and equipment used in producing goods are tax-exempt.

Labor in most cases isn’t taxable in Maryland.  For instance, let’s say you broke the screen to your cell phone and take it to a cell phone repair shop to have it fixed.  Sales tax would be added to the selling price of the new screen and any additional parts to fix the phone.  The labor to replace the screen isn’t taxable.  However, a business that makes furniture will indirectly have sales tax on labor.  In this instance, let’s say this business is building a dining room table for a customer.  Through labor, the pieces of wood are shaped, sanded and painted to build this piece of furniture.  While the labor isn’t directly taxable, sales tax is charged to the final selling price of the table. 

Digital Products

Digital products are currently not taxable.


Most services aren’t taxable in Maryland, however there are a few exceptions, some of which include:

  • Short-term lodging

Sales tax reporting

How is sales tax collected?

When a business makes a sale of a taxable product or service, the business charges the appropriate sales tax rate to the customer.  This tax is collected by the business who then sends it to the Comptroller of Maryland.

How much sales tax is charged?

The sales tax rate that is charged varies depending on the address of the business if the purchase is made or shipped from a business located in the state or where the transaction took place such as a fair or tradeshow.

In addition to the statewide tax, there are additional sales taxes that may be added by cities and municipalities.  To find the sales tax for your location, see the sales tax rate guide from the Comptroller of Maryland.

 When are Maryland sales tax returns due?

The Comptroller of Maryland will determine a filing frequency based on the expected volume of annual sales, which will be monthly, quarterly, semiannually or annually.  Generally, a business collecting over $700 in sales tax monthly will file monthly. 

Filings are due the 20th day of the month following the reporting period, unless the 20th falls on a weekend or federal holiday, in which case would move to the next business day.

Even if the business had no sales during the reporting period, a filing is still required indicating no sales occurred.

Sales tax on purchases for resale

A business is able to purchase items to resell without paying state sales tax.  The tax liability is passed from the wholesaler or distributor to the retailer who will then charge sales tax to the end user of the item. 

Wholesalers and distributors will require a sales tax number, and in many cases require the reseller to fill out the Maryland Resale Certificate to document the items being purchased are for resale.
