Maryland Sales Tax Nexus

Maryland Risk Profile
Maryland Risk Profile
The Trigger: $100,000 in annual gross sales.
(Note: Maryland officially repealed the “200 transactions” rule on July 1, 2024. It is now a revenue-only state.)
Physical Nexus: Standard triggers apply (offices, employees, inventory). Maryland is highly proactive in monitoring 3PL warehouse data to identify out-of-state businesses with physical inventory in the state.
Effective Date: October 1, 2018.
Look-back Exposure: Generally 3 years. Maryland is NOT a member of the Streamlined Sales Tax (SST) agreement and is known for its specialized audit division that focuses on high-growth e-commerce and tech sectors.
Danger Level: HIGH (The Digital Products & Advertising Risk)
Maryland’s tax on digital products and its first-in-the-nation digital advertising tax make it a high-risk jurisdiction for tech companies. The state is aggressive in auditing “cloud-based” transactions, and remote companies often find themselves with significant back-tax liability for SaaS and digital streaming services.
The Trap: The August Tax Holiday
Maryland’s “Shop Maryland Energy” and “Shop Maryland Tax-Free Week” create temporary exemptions for specific items. Failing to adjust your tax collection engine for these specific dates and price caps ($100 for clothing) can result in over-collection or under-collection, both of which are common audit targets.
Maryland State Tax Nexus Summary
Maryland utilizes a revenue-based economic nexus standard and has been a leader in implementing taxes on the digital economy. For out-of-state businesses, Maryland presents unique risks regarding digital product taxability and localized auditing.
Sales Tax Nexus
Remote sellers and marketplace facilitators establish nexus in Maryland if they meet the following threshold in the current or previous calendar year:
- Economic Threshold: $100,000 or more in gross retail sales delivered into Maryland.
- Update: As of July 1, 2024, Maryland no longer utilizes a transaction count (formerly 200 sales) to determine nexus.
Physical nexus is triggered immediately by having a physical presence in the state, such as an office, remote employees, or inventory stored in a Maryland warehouse or fulfillment center.
Income and Digital Advertising Taxes
Maryland imposes an 8.25% corporate income tax. Furthermore, large technology firms with global revenues exceeding $100 million must monitor the state’s unique Digital Advertising Tax, which applies specifically to revenue generated from digital ads served within Maryland.
Taxability of Groceries and Digital Goods
While Maryland generally exempts groceries, it is one of the most aggressive states in taxing the digital economy. Streaming, downloads, and Software-as-a-Service (SaaS) are generally subject to the 6% state sales tax.
Conclusion
Because Maryland is not an SST member, their rules can be more rigid and their audits more specialized. We recommend a full taxability review for businesses selling digital services or those operating near the $100,000 sales threshold.
