Foreign sellers may need to collect Maryland sales and use tax when they sell taxable goods or services for delivery or use in Maryland and meet the state’s rules for doing business there. Maryland’s remote-seller economic nexus test is based on Maryland sales revenue or transaction count; having no U.S. office does not by itself settle the question. The Comptroller of Maryland administers the tax, and sellers register and manage accounts through Maryland Tax Connect.
Maryland has one statewide general sales tax rate, but not every sale is taxed at the same rate: certain digital products and services, including some SaaS offerings, have specific tax treatment. Marketplace facilitators generally collect tax on sales they facilitate, while sellers may still have obligations for direct sales, registration, records, and returns. The sections below explain how to assess those responsibilities and where to confirm your exact position.
When foreign sellers must collect Maryland sales tax
Maryland can require an out-of-state seller, including a seller based outside the United States, to register and collect sales and use tax on taxable sales delivered into Maryland. The key questions are whether the seller has physical nexus or meets Maryland’s economic nexus test, and whether the products or services sold are taxable. A foreign address or lack of a U.S. office does not automatically remove a seller’s Maryland obligations.
For remote sellers, Maryland’s test looks at gross revenue from sales of tangible personal property or taxable services delivered in the state, or the number of separate transactions for delivery into Maryland. Marketplace sales are included when assessing the threshold. If you are near the threshold, sell through more than one channel, or are unsure how a product is classified, confirm the current treatment with the Comptroller of Maryland or ask a compliance service to review your facts.
Check Maryland’s economic nexus thresholds
The Comptroller of Maryland identifies two alternative tests for an out-of-state vendor: gross revenue exceeding $100,000 from sales of tangible personal property or taxable services delivered in Maryland, or 200 or more separate transactions involving such sales for delivery into Maryland. Meeting either test can require registration and collection. The test applies to activity in the previous or current calendar year.
Count Maryland sales across your channels, including sales facilitated by a marketplace, rather than looking only at orders placed on your own website. Keep records that distinguish Maryland deliveries, taxable and nontaxable items, direct sales, and marketplace-facilitated sales. Threshold rules and product classifications can change; check the current Comptroller guidance before relying on a calculation.
Know which activities create physical nexus
Physical activities in Maryland can create a connection to the state independent of remote-sales thresholds. Examples to investigate include maintaining inventory in Maryland, having employees or representatives work there, or using people in the state to solicit or fulfill sales. The precise result depends on what the people or business operations do and how they are arranged.
Review fulfillment arrangements, temporary business activity, and any Maryland-based personnel or agents. Do not assume that a third party’s warehouse or a short visit is irrelevant, or that it automatically creates nexus; the facts matter. If your business has any in-state presence, ask the Comptroller of Maryland or a tax professional to assess it before deciding whether registration is required.
Register for a Maryland sales and use tax account
Foreign sellers that are required to collect Maryland sales and use tax need to register with the Comptroller of Maryland. The state’s registration system is Maryland Tax Connect. The Comptroller’s business registration information directs businesses to use the portal’s “Register a Business” option; the Combined Registration Application is also used to apply for Maryland tax accounts.
Prepare accurate business and ownership details, contact information, and a clear description of your sales and products before starting. Once registered, use the account to manage tax matters and follow the filing schedule assigned by the Comptroller. Registration requirements can depend on your activities and sales channels, so confirm your obligation rather than registering—or deciding not to register—on an assumption.
Identify taxable sales and the Maryland tax rate
Maryland’s general statewide sales and use tax rate is 6% for taxable sales of tangible personal property and taxable services subject to that rate. Maryland is not a home-rule state for sales tax: local jurisdictions do not administer separate local sales tax rates. However, the statewide rate is not the whole story for every product category.
Maryland explicitly taxes digital products and digital codes. SaaS and other software offerings require careful classification: the Comptroller explains that SaaS for individual use may be treated as a taxable digital product at 6%, while qualifying services used in an enterprise computer system may be subject to a 3% rate. The applicable rate depends on the product, use, and statutory classification; do not apply one rate to every digital sale without checking the current Comptroller guidance.
Taxability also depends on the item or service and any applicable exemption. Separate taxable sales from exempt or nontaxable sales in your records, and retain documentation supporting an exemption. If your catalog includes subscriptions, downloads, software access, or bundled offerings, have each category reviewed before configuring collection.
Understand marketplace facilitator responsibilities
Maryland law generally requires a marketplace facilitator to collect the applicable sales and use tax on taxable sales it facilitates for marketplace sellers. A seller is not required to collect the tax on a facilitated sale to the extent the facilitator collects it. Confirm that the marketplace is collecting Maryland tax on the relevant products and transactions, and retain reports that show facilitated sales and tax collected.
Marketplace collection does not necessarily cover your direct website sales or other channels. Maryland’s Comptroller states that a marketplace seller whose sales are all through a marketplace facilitator does not have to register solely for those sales, but a seller that also makes direct sales may need to register if it meets the out-of-state vendor requirements. Marketplace sales also count toward the remote-seller threshold, so track them even when the facilitator remits the tax.
File Maryland sales tax returns on time
Registered sellers must file returns according to the filing frequency assigned by the Comptroller of Maryland and report the activity required for the period. A return may still be required for a period with no taxable sales; follow the instructions for your account rather than assuming that no activity means no filing. Maryland Tax Connect provides the state’s online account and filing route.
The return and payment are generally due on the 20th day of the month following the end of the reporting period. If that date falls on a Saturday, Sunday, or legal holiday, the due date moves to the next business day. Check the due date shown for your account and the current Comptroller instructions, especially if your filing period or account status has changed.
Track filing frequency, payments, and late-filing exposure
The Comptroller initially assigns a filing schedule and may change it based on the amount of tax paid. Maryland schedules can be monthly, quarterly, semiannual, or annual; the frequency assigned to your account controls. Monitor notices and Maryland Tax Connect so a schedule change does not leave you filing late or paying on the wrong timetable.
Late returns, unpaid tax, and failure to collect tax that was due can lead to additional amounts owed and other consequences under Maryland law. The amount and treatment depend on the circumstances, so this page does not estimate a penalty. If a return or payment is overdue, address it promptly through the Comptroller and seek help calculating the liability; do not wait for a notice to reconcile your records.
Get help managing Maryland sales tax compliance
Cross-border sellers often need to coordinate product taxability, currency and order records, marketplace reports, nexus monitoring, registration, returns, and payment deadlines. Keep records that clearly separate taxable and nontaxable sales and purchases; the Comptroller says sales and purchase records must be kept for four years. Reconcile marketplace tax collected with direct-channel sales so that facilitated transactions are not confused with your own collection obligations.

Frequently asked questions
Does Maryland require out-of-state sellers to collect sales tax?
Yes, an out-of-state seller may have to collect Maryland sales and use tax on taxable sales delivered into the state if it has physical nexus or meets Maryland’s economic nexus test. The obligation depends on the seller’s activities, sales volume, and product taxability. Foreign sellers should assess the same Maryland connection and product rules rather than assuming that being based abroad exempts them.
What is Maryland’s economic nexus threshold for remote sellers?
The Comptroller identifies either gross revenue exceeding $100,000 from sales of tangible personal property or taxable services delivered in Maryland, or 200 or more separate transactions for delivery into Maryland. The test applies to the previous or current calendar year, and marketplace sales are included in the threshold calculation. Check current Comptroller guidance when calculating your position.
Do foreign sellers need to register for Maryland sales tax?
A foreign seller needs to register when its Maryland activities require it to collect sales and use tax, including when it meets the remote-seller test or has relevant physical nexus. Registration is handled through Maryland Tax Connect. If all sales are made through a marketplace facilitator, the seller’s registration position may differ, but direct sales and other activities must still be assessed.
How do I register for a Maryland sales and use tax account?
Use Maryland Tax Connect and select “Register a Business,” or follow the Comptroller’s instructions for the Combined Registration Application. Provide accurate business details and identify the tax account you need. After registration, monitor the account for your assigned filing frequency and due dates.
What is Maryland’s sales tax rate?
Some categories have different treatment: for example, qualifying data or information technology services may be taxed at 3%, while certain digital products and SaaS sales are subject to specific classification rules. Confirm the rate for the actual product and use with the Comptroller.
Does selling through a marketplace require a seller to collect Maryland tax?
A marketplace facilitator generally collects and remits tax on taxable sales it facilitates, and the seller is not required to collect that tax to the extent the facilitator does so. A seller may still need to register and collect on direct sales, and marketplace sales count toward the remote-seller threshold. Keep marketplace reports and verify which transactions the facilitator covered.
What sales are taxable in Maryland?
Maryland taxes taxable sales of tangible personal property and specified taxable services, and it explicitly taxes digital products and digital codes. SaaS and software can fall into different categories and rates depending on the product and its use. Review the Comptroller’s current product guidance and document any exemption you apply.
How often do Maryland sellers need to file sales tax returns?
The Comptroller assigns the filing frequency, which may be monthly, quarterly, semiannual, or annual, and can change it based on tax paid. Returns and payments are generally due on the 20th day of the month after the reporting period ends, with the next-business-day rule when the date falls on a weekend or legal holiday. Follow the due date and schedule shown for your account.
