Why Maryland Sales Tax Matters
Maryland is one of the largest ecommerce markets in the United States and home to a major concentration of Amazon FBA fulfillment centers across Sparrows Point (Baltimore County), Aberdeen, Hagerstown, Cecil County (North East), Baltimore.
If you sell through Amazon, Shopify, Walmart, or any other marketplace, Maryland’s economic nexus rules mean you can owe sales tax even if your company is registered outside the U.S. Maryland sales tax nexus is established when a business has a significant connection to the state — either by exceeding a sales threshold or through inventory, employees or contractors physically located in Maryland.
Failing to register or file properly can result in:
- State tax penalties and backdated interest
- Account suspensions on Amazon, Walmart or Shopify
- Rejection of future foreign business registrations
- Criminal liability for unremitted tax above $1,500
Key Takeaways:
- $100,000 OR 200 transactions (either trigger) in gross Maryland revenue over the preceding 12 months creates economic nexus.
- Storing FBA inventory in any Maryland warehouse creates physical nexus immediately — no revenue threshold applies.
- Marketplace facilitator laws do not exempt you from registration if you also sell through your own website or have physical presence.
- Maryland is not a Streamlined Sales Tax member — you must register directly with the Comptroller of Maryland.

Understanding Maryland Sales Tax
Maryland sales tax is a consumption tax applied to retail sales of tangible personal property and most taxable services. The state imposes a base rate of 6.00%, and local jurisdictions (cities, counties, transit authorities and special purpose districts) can add up to 0.00% on top, capped at a combined maximum of 6.00%.
Sales tax is collected by sellers with nexus in Maryland and remitted to the Comptroller of Maryland (MD Comptroller).
The Sales Tax Structure
Maryland uses destination-based. Remote sellers can elect to collect a single statewide local use tax rate of N/A% (for N/A) instead of tracking the rate at every individual delivery address — making the combined rate a flat 8.00% on every Maryland sale.
| Location | Combined Rate | Breakdown |
|---|---|---|
| Anywhere in Maryland (general goods) | 6.00% | 6.00% state only — no local sales tax |
| SaaS B2B / enterprise sales | 3.00% | Reduced rate for business customers (since July 1, 2025) |
| SaaS B2C / consumer sales | 6.00% | Standard rate for individual consumers |
| Alcoholic beverages | 9.00% | Higher rate on alcohol sales |
👉 Use the MD Comptroller City Sales and Use Tax Rates to confirm any local rate.
Economic Nexus Thresholds in Maryland
Maryland enforces economic nexus for both domestic and foreign sellers. You must register for a Maryland Sales and Use Tax License if your total Maryland revenue is $100,000 OR 200 transactions (either trigger) or more in the current or previous calendar year.
What counts toward the threshold:
- Gross revenue from taxable and non-taxable sales of tangible personal property and services delivered into the state
- Sales made through marketplace providers (Amazon, Walmart, Etsy, eBay)
- Separately stated handling, transportation and installation charges
- Sales for resale and sales to tax-exempt entities
This applies even if you:
- Operate entirely outside the U.S.
- Sell exclusively via Amazon, Walmart or Shopify
- Have no employees or offices in the state
Example: A UK-based Shopify store ships $600,000 of products into Maryland between June 1, 2025 and May 31, 2026. The threshold is crossed in May. The seller must obtain a permit and begin collecting and remitting tax by September 1, 2026 (the first day of the fourth month after crossing).
Termination: Once registered, you can only stop collecting if your Maryland revenue stays below $100,000 OR 200 transactions (either trigger) for 12 consecutive months — a single low quarter does not lift the obligation.
Physical Nexus Triggers in Maryland
Even without crossing the $100,000 OR 200 transactions (either trigger) sales threshold, your business has physical nexus in Maryland if you:
- Store inventory in a Maryland Amazon FBA centre or 3PL warehouse (this is the most common trigger for FBA sellers)
- Employ staff or contractors in the state — including delivery agents, installers or sales reps
- Attend trade shows or temporary retail events (even a single day creates exposure)
- Use in-state affiliates or influencers who actively promote your products
- Use a drop-shipper that fulfills orders from inventory held in Maryland
FBA inventory in Sparrows Point, Aberdeen, Hagerstown, Cecil County or Baltimore creates physical nexus immediately. And the SaaS dual-rate system catches a lot of SaaS vendors off guard — if you can’t distinguish B2B from B2C customers, MD Comptroller may assess at the higher 6% rate retroactively across all your sales.

Obtaining a Maryland Sales Tax Permit
The Comptroller of Maryland (MD Comptroller) administers all sales tax registration in Maryland. Most applications are filed online through the Comptroller eSystems portal.
How to register: Submit Combined Registration Application (Form CRA), filed online through Maryland Tax Connect through the eSystems portal. You will need your legal business name, any DBA, federal EIN, state of formation, business address, NAICS code, and identification for the responsible party. Online filing typically takes 20–40 minutes.
Cost and timeline: Free. Permits are typically issued within 5–10 business days for online applications after a complete application is submitted. Once approved you receive your Maryland Sales and Use Tax License used for all subsequent Form 202 filings.
Understanding Maryland sales tax nexus: Before registering, confirm whether your business has nexus through physical presence (inventory, employees, contractors) or through the $100,000 OR 200 transactions (either trigger) economic nexus threshold. Out-of-state sellers and marketplace sellers should pay particular attention — even businesses with no physical presence in Maryland must register if they meet the threshold.
Foreign Seller Maryland Sales Tax Registration Requirements
Follow these steps to obtain your Maryland Sales and Use Tax License as a non-U.S. business:
- Confirm your business type (foreign LLC, corporation, sole proprietor or other entity).
- Apply online via the Comptroller of Maryland, or email Combined Registration Application (Form CRA), filed online through Maryland Tax Connect to (international sellers register through Maryland Tax Connect; contact MD Comptroller Taxpayer Service at 410-260-7980 if you cannot complete registration without a U.S. SSN) if you do not yet have an eSystems account.
- Prepare the required documents:
- Federal EIN (Employer Identification Number)
- Formation or incorporation certificate
- Passport or government ID of the responsible officer
- Foreign business address (a U.S. address is not required)
- Wait for approval (usually within 5–10 business days for online applications).
- Begin collecting and remitting Maryland sales tax on all taxable sales delivered into the state.
After registration you must file a Maryland sales and use tax return on your assigned schedule (monthly, quarterly or annual), even if you have zero sales for a period.

Filing & Payment Rules
Once registered you must file Maryland sales and use tax returns through the MD Comptroller’s Webfile portal, EDI, or TEXNET (for high-volume payers).
| Requirement | Details |
|---|---|
| Filing Frequency | MD Comptroller assigns frequency based on liability: monthly (default), quarterly, or annual for low-volume sellers. |
| Due Dates | 20th of the month following the reporting period (electronic filing required for most sellers). |
| Payment Methods | Electronic filing through Maryland Tax Connect is mandatory for most sellers. Payment via ACH-debit, ACH-credit, or credit card. |
| Discount for Timely Filing | Maryland pays a vendor discount of 1.2% on the first $6,000 of state tax timely paid each return, plus 0.9% on tax above $6,000, capped at $500 per return. |
| Penalties | Up to 25% combined late-filing and late-payment penalties; daily interest at the MD Comptroller floating rate; criminal liability for wilful non-remittance. |
- Sales tax automation (or a done-for-you service) helps streamline the filing, payment and reconciliation process — particularly important for international sellers managing returns in multiple states simultaneously.
⚠️ Noncompliance can result in permit revocation, audit assessments, account holds with marketplaces, and — for unremitted tax of $1,500 or more — criminal prosecution.
Marketplace Facilitator Laws in Maryland
Since October 1, 2019, Maryland requires marketplace facilitators (Amazon, eBay, Walmart, Etsy, TikTok Shop) to collect and remit sales tax on behalf of third-party sellers.
However, this does not remove your obligations as a seller:
- If you have physical presence in Maryland (FBA inventory, employees, contractors, office), you must still register and file — even if 100% of your sales are through marketplaces.
- If you also sell through your own Shopify, WooCommerce or branded site, you are responsible for collecting and remitting tax on those direct sales.
- Marketplace sales still count toward the $500,000 economic nexus threshold.
- You must keep records of all marketplace sales for at least 4 years for audit purposes.
2025–2026 update: Three major Maryland-specific points: (1) NO LOCAL SALES TAX — flat 6% rate statewide. (2) The custom software exemption was REPEALED effective July 1, 2025 — custom software is now fully taxable. (3) SaaS uses a unique dual-rate structure as of July 1, 2025: 3% for B2B/enterprise sales, 6% for B2C/consumer sales. SaaS sellers must classify each customer correctly to bill the right rate. (4) Maryland INCLUDES marketplace sales in the $100,000 / 200-transaction threshold for remote-seller registration.
Example: A South African Amazon FBA seller with $600,000 in Maryland sales (all via Amazon) and inventory stored in Houston must register and file zero-tax marketplace returns — because Amazon already collected the tax, but the MD Comptroller still expects the seller to report total sales activity due to physical nexus.
Sales Tax vs. Use Tax
Maryland imposes both sales tax and use tax:
- Sales Tax: Charged by sellers on retail sales delivered within Maryland.
- Use Tax: Owed directly by the buyer when sales tax was not collected at the point of sale — most commonly on out-of-state or online purchases of taxable goods. The use tax rate equals the sales tax rate at the buyer’s location.
If your business buys equipment, fixtures or supplies from outside Maryland for use within the state, you may owe use tax. Remote sellers who elect the single local use tax rate collect a flat N/A% local rate plus the 6.00% state rate, regardless of the delivery address.
Maryland Sales Tax Filing & Due Dates
Filing frequency is assigned by the Comptroller based on your prior-year tax liability:
- Monthly — high-volume sellers
- Quarterly — most mid-sized sellers
- Annual — low-activity sellers
Returns are due 20th of the month following the reporting period (electronic filing required for most sellers).
Discounts and incentives for filing on time:
Maryland pays a vendor discount of 1.2% on the first $6,000 of state sales tax timely paid per return, plus 0.9% on tax above $6,000. The discount is capped at $500 per return. To qualify you must file and pay on time through Maryland Tax Connect.
Late filings incur:
Late filing and payment penalties combine for up to 25% of unpaid tax. Interest accrues daily at the MD Comptroller floating rate (currently around 9% APR). MD actively pursues non-compliant remote sellers via data matching with marketplaces and the IRS. Wilful failure to remit collected tax carries criminal liability under Maryland Code §13-1018.
Maryland Sales Tax Exemptions
Not every sale into Maryland is taxable. The most common exemptions for ecommerce sellers are:
- Most unprepared groceries (bread, milk, eggs, produce, flour, sugar) — but candy, soft drinks, energy drinks and individual snack portions are taxable
- Prescription medications
- Sales to U.S. government agencies and qualifying nonprofits
- Resale purchases made with a valid resale certificate
- Annual Sales Tax Holiday — Maryland runs two annual sales tax holidays: (1) Energy Star Weekend, February 14–16, 2026 — Energy Star appliances and solar water heaters tax-exempt; (2) Shop Maryland Tax-Free Week, August 9–15, 2026 — clothing/footwear ≤$100 and the first $40 of any backpack are tax-exempt.
Taxability quirks for online sellers:
- Shipping: Exempt if separately stated on the invoice; taxable if combined with handling charges (handling is always taxable)
- SaaS: Yes — Maryland taxes SaaS using a UNIQUE dual-rate structure since July 1, 2025: 3% on B2B / enterprise SaaS sales, and 6% on B2C / consumer SaaS sales. Custom software is also taxable since July 1, 2025 (the prior exemption was repealed)
- Digital goods: Yes — at the full 6% rate. Maryland taxes streaming, e-books, downloadable music, apps, games and digital subscriptions — e-books, downloadable music, software and streaming follow the same rules as their physical equivalents
- Clothing: Yes year-round at 6%, except during the August Back-to-School Sales Tax Holiday (clothing under $100 per item, plus the first $40 of backpacks)
Always keep valid exemption certificates on file — the Comptroller frequently audits remote sellers and disallows undocumented exemptions.
Sales Tax for Online Sellers (Amazon, Shopify, Walmart)
For online sellers, Maryland compliance depends on your fulfillment model and sales channels:
- Marketplace facilitators like Amazon, Walmart, Etsy and eBay collect and remit Texas sales tax automatically on sales made through their platforms.
- Direct Shopify, WooCommerce or BigCommerce sellers must register, collect and remit tax themselves — Shopify is not a marketplace facilitator (except for Shop App orders).
- If you sell through both, you must report all sales on your Texas return — including marketplace sales — and back out the marketplace-collected portion as deductions.
- FBA sellers: Amazon operates major fulfillment centers in Sparrows Point/Baltimore, Aberdeen, Hagerstown and Cecil County, anchoring Mid-Atlantic distribution. If Amazon stores even one unit of your inventory in Maryland, you have physical nexus and must register, regardless of revenue.
Tip: Combine marketplace and direct sales under one Comptroller filing to avoid reporting discrepancies that trigger audits.
Calculating and Remitting Sales Tax
To calculate the correct tax on a Texas sale:
- Identify the delivery address rate using the Comptroller City Sales and Use Tax Rates — or, as a remote seller, elect the flat N/A% single local use tax rate for simplicity.
- Multiply your taxable sales by the combined rate. Sales tax applies to most tangible personal property; most pure services are not taxable, but data processing, telecommunications and several other named services are.
- Round to the nearest cent.
For example, a $100 taxable sale at the maximum combined 6.00% rate generates $6.00 in sales tax.
To eliminate the manual work entirely, Sales Tax Compliance USA takes over the full collect→reconcile→file→remit cycle for you. One fee, no software for you to learn.
Penalties & Risks for Noncompliance
Ignoring Maryland nexus obligations is expensive. The MD Comptroller routinely audits both U.S. and foreign sellers using Amazon FBA inventory reports, Shopify data, marketplace 1099-K filings and IRS information sharing.
| Violation | Penalty |
| Late filing of return | Combined late-filing and late-payment penalties up to 25% of unpaid tax |
| Late payment of tax | Combined with late-filing penalty up to 25% maximum |
| Interest on unpaid tax | MD Comptroller floating rate (currently around 9% APR), accrues daily |
| Failure to register / collect (when required) | MD pursues via data matching with marketplaces and IRS |
| Wilful failure to remit collected tax | Criminal liability under Maryland Code §13-1018 |
🚫 Amazon, Walmart or Shopify may suspend your account if Maryland notifies them of a registration deficiency. Don’t risk your U.S. operations — register before the Comptroller contacts you.
Maryland is not a member of the Streamlined Sales Tax Agreement — you cannot use the multi-state SSTRS shortcut. Each registration is filed directly with the Comptroller.

FAQs for Maryland Sellers
1. Do I need to register if Amazon already collects Maryland sales tax for me?
Maybe. Maryland INCLUDES marketplace sales in the $100,000 / 200-transaction threshold, so even marketplace-only sellers can trigger nexus. If you also sell on your own Shopify or branded site, those direct sales must be added to your marketplace sales when checking the threshold. And FBA inventory in any Maryland warehouse (Sparrows Point, Aberdeen, Hagerstown, Cecil County, Baltimore) creates physical nexus regardless of revenue.
2. How does Maryland's SaaS dual-rate work?
Since July 1, 2025, Maryland taxes SaaS at TWO different rates: 3% on B2B / enterprise sales (sales to businesses for business use) and 6% on B2C / consumer sales (sales to individual consumers). You must classify each customer correctly. If you can’t substantiate a B2B classification (typically with a business exemption certificate or B2B registration), MD Comptroller defaults to the higher 6% rate.
3. Can I register for Maryland sales tax without a U.S. address?
Yes. MD Comptroller accepts foreign business addresses on the Combined Registration Application (Form CRA) through Maryland Tax Connect. You will need a Federal EIN. Sales Tax Compliance USA can obtain the EIN and complete the registration for foreign entities as part of our service.
4. How long does Maryland sales tax registration take?
Online applications through Maryland Tax Connect typically take 5–10 business days. There is no application fee.
5. Did Maryland really start taxing custom software in 2025?
Yes. The custom software exemption was REPEALED effective July 1, 2025. Custom-built software, professional services, and SaaS are now all taxable in Maryland. Software vendors who relied on the prior exemption need to update their tax engines and review historical exposure.
