Maryland Sales Tax Guide 2026: Complete Compliance Guide for Remote Sellers
Navigating Maryland’s sales tax landscape is essential for remote sellers conducting business in the Old Line State. Following the South Dakota v. Wayfair decision, Maryland implemented economic nexus laws that significantly impact out-of-state businesses. This comprehensive guide will help you understand your remote seller obligations and ensure full compliance with Maryland’s sales tax requirements.
Whether you’re selling physical goods, digital products, or taxable services into Maryland, understanding the state’s sales tax nexus by state requirements is crucial. Maryland’s destination-based sourcing system, combined with varying local tax rates, creates a complex environment that demands careful attention from multi-state sellers.
Maryland Economic Nexus Threshold 2026
Maryland’s economic nexus law requires remote sellers to collect and remit sales tax if they exceed specific economic nexus thresholds. As of 2026, you must register and collect Maryland sales tax if your business has:
- $100,000 in gross revenue from Maryland sales in the current or previous calendar year, OR
- 200 or more separate transactions delivered into Maryland
The state monitors these thresholds using the “or” condition, meaning exceeding either the dollar amount OR the transaction count triggers registration requirements. This dual-threshold approach is common among states implementing Wayfair compliance measures.
It’s important to note that Maryland counts all sales toward the threshold, including tax-exempt sales. This differs from some states that only count taxable sales. Remote sellers must carefully track their Maryland sales activity to determine when nexus is established.
Once nexus is established, you must register with the state within 60 days. Failure to comply can result in penalties, interest, and potential back-tax liability. For assistance with registration, Abaca Tax provides expert guidance to help remote sellers navigate Maryland’s requirements efficiently.
Understanding Maryland Sales Tax Nexus
Beyond economic nexus, Maryland recognizes several types of sales tax nexus that can obligate your business to collect tax:
Physical Presence Nexus
Traditional physical presence nexus still applies in Maryland. If you have:
- An office, store, or warehouse in Maryland
- Employees, salespeople, or contractors working in the state
- Inventory stored in Maryland (including FBA inventory)
You automatically have nexus regardless of your sales volume.
Affiliate Nexus
Maryland also maintains affiliate nexus provisions. If your business has a relationship with a Maryland entity that refers customers for commission, this can create nexus.
Given the complexity of determining nexus, many businesses benefit from a comprehensive sales tax nexus study to identify all states where they have collection obligations. States Sales Tax specializes in these studies, helping businesses understand their complete nexus footprint across all jurisdictions.
Maryland Sales Tax Rate Structure
Maryland employs a destination-based sourcing system, meaning the tax rate is determined by the delivery location of the goods or services. Understanding this structure is critical for accurate ecommerce sales tax compliance.
State Sales Tax Rate
Maryland’s statewide sales tax rate is 6%, which applies to all taxable sales. Unlike many states, Maryland does not exempt food, clothing, or prescription drugs from sales tax.
Local Sales Tax Rates
Local jurisdictions in Maryland can impose additional taxes ranging from 0% to 3.2%. These rates vary by county and city, creating a complex rate landscape. For example:
- Baltimore City: Additional 2.5% for accommodations
- Various counties: Additional taxes on prepared foods and beverages
- Special taxing districts for tourism and transportation
Remote sellers must use geolocation tools or sales tax software to ensure accurate rate determination. The complexity of rate structures in states like Maryland rivals that of California and Colorado.
Registering for Maryland Sales Tax
Once you’ve determined you have nexus in Maryland, registration is the next critical step. Maryland requires all sellers with nexus to register through their online portal.
Online Registration Process
The Maryland Comptroller’s Office offers registration through Maryland Business Express, the state’s unified business registration system. You’ll need:
- Federal Employer Identification Number (EIN)
- Business entity information
- Projected monthly sales volume
- NAICS code for your primary business activity
For expert assistance with registration, Abaca Tax offers comprehensive registration services, ensuring your business is properly set up to collect and remit Maryland sales tax from day one.
What You’ll Receive
After successful registration, you’ll receive a sales tax license number and instructions for filing returns. Maryland does not charge a fee for sales tax registration.
Filing Requirements and Deadlines
Maryland assigns filing frequencies based on your anticipated tax liability:
Filing Frequency Thresholds
- Monthly: Businesses with more than $15,000 in annual Maryland tax liability
- Quarterly: Businesses with $601 to $15,000 in annual liability
- Annual: Businesses with $600 or less in annual liability
Due Dates
- Monthly: 20th day of the following month
- Quarterly: April 20, July 20, October 20, and January 20
- Annual: January 20
If the due date falls on a weekend or holiday, the deadline extends to the next business day. Late filing and payment penalties can be significant, including 10% of the tax due plus interest.
Managing multi-state compliance can be overwhelming. States Sales Tax provides ongoing compliance services, including return preparation and filing, to ensure you never miss a deadline across any state.
Recent Changes and Updates
Maryland continues to refine its sales tax laws in response to Wayfair compliance requirements and marketplace changes.
Marketplace Facilitator Laws
Maryland requires marketplace facilitators (like Amazon, eBay, and Etsy) to collect and remit sales tax on behalf of third-party sellers using their platforms. This means if you sell exclusively through marketplaces, you may not need to register separately in Maryland.
Digital Products Taxation
Maryland has expanded taxation on digital products, including streaming services, digital downloads, and software-as-a-service (SaaS) subscriptions. Remote sellers providing digital goods should carefully review their product classifications.
Staying current with these changes is essential. Our sales tax audit defense resources can help you prepare for potential challenges.
FAQ

Does Maryland tax shipping charges?
Shipping charges are generally taxable if the item being shipped is taxable. If you’re shipping tax-exempt items, the shipping is also exempt.
What happens if I don’t register when required?
Non-compliance can result in penalties, interest on unpaid taxes, and potential back-tax liability. Understanding when to collect sales tax is critical to avoiding these consequences.
Can I use my home state’s resale certificate in Maryland?
Maryland does not accept out-of-state resale certificates. You must apply for a Maryland resale certificate to make tax-exempt purchases for resale.
