Is SaaS taxable in Maryland?
The rule
Maryland treats SaaS as both a digital product and a software publishing service, taxed at 3% when bought for use in a business computer system and at 6% when bought for individual use.
The main exception
SaaS bought for individual use is taxed at 6%, and where either rate could apply Maryland requires the higher one.
What to do
Record whether each customer buys for business (enterprise) or individual use, so you charge 3% or 6% correctly.
Is your product taxable in Maryland?
Whether a particular product is taxed in Maryland can depend on two things: how the software reaches the customer and how you write the invoice.
Does it matter how the software reaches the customer?
In Maryland, downloaded software is taxable. Software counts as downloaded when the customer installs a copy, such as a desktop app, an agent or an offline client, even if most of the product runs online.
Does it matter how you write the invoice?
In Maryland, setup, implementation and training fees are taxable at 3%. Listing them on their own invoice lines, rather than inside one software price, is what lets them be treated separately.
How are other software products and services taxed in Maryland?
SaaS rarely ships alone. This is how Maryland treats the products and charges that usually sit next to it on an invoice.
| Product or charge | Treatment |
|---|---|
| Downloaded software | Taxable |
| Custom software | Taxable At 3% |
| Cloud infrastructure and platforms (IaaS, PaaS) | Taxable At 3% |
| AI tools and API access | Taxable |
| Digital goods (e-books, music, video) | Taxable At 6% |
| Maintenance and support | Taxable |
| Setup, implementation and training | Taxable At 3% |
Does Maryland tax B2B and B2C SaaS differently?
Yes. In Maryland, SaaS bought for business (enterprise) use is taxed at 3%, and SaaS bought for individual use is taxed at 6%.
How much sales tax do you charge on SaaS in Maryland?

Do cities or counties tax SaaS differently?

General sales tax rates, including any local rates, are in our Maryland sales tax guide.
Do you need to register for sales tax in Maryland?
Physical and economic nexus
Registration follows nexus. Once you have nexus in Maryland and sell something taxable there, you need to register. Nexus comes from a physical presence, such as an office, staff or inventory in the state, or from passing an economic threshold.
In Maryland, the economic nexus threshold is $100,000 in sales or 200 transactions over the previous or current calendar year. Exempt sales still count toward it. Our Maryland nexus guide covers the rules in full.
Which address sets the rate
For remote sellers, the rate is based on where your customer is, not where your business or servers are. Buyers with users in more than one state can give you a multiple points of use certificate and pay Maryland tax only on the share used there.
Buyers who do not pay tax
Some buyers can give you a certificate instead of paying tax. In Maryland, that includes resellers, government agencies, nonprofits holding a Maryland Exemption Certificate and qualifying cybersecurity businesses buying cloud computing. Collect the certificate at the time of sale and keep it, because in an audit it is the only thing standing between you and the tax.
How to register, collect and file in Maryland
Register
If you need to register, do it with the Comptroller of Maryland through MDTaxConnect (mdtaxconnect.gov). Note your account number and the filing frequency you are given, since both decide when and how you file.
Collect the right amount
Charge tax only on what Maryland taxes. Collecting tax that is not owed creates its own refund and audit problems.
- List services on their own invoice lines, so each charge is taxed on its own terms.
- Describe each product on the invoice the way it actually reaches the customer: online access, a download or something shipped.
- Recheck the treatment whenever you add a desktop app, a hardware option or a new add-on, since each can change what is taxable.
File and keep records
Your filing frequency is assigned when you register: monthly, quarterly or annually, depending on how much tax you collect. Returns are due by the 20th of the month after each period ends.
You must file a return for every period, even when no tax is due.
Keep invoices, exemption certificates and returns for at least four years. That paperwork is what decides the taxable amount if you are audited years later.
What should SaaS businesses watch when selling in Maryland?
Past sales where no tax was charged
If you should have been collecting and were not, the Comptroller of Maryland can assess the unpaid tax plus a penalty of up to 25% of the tax and interest.
A voluntary disclosure agreement can reduce penalties if you come forward first. Work out which past sales were taxable before you come forward, so you know the size of the exposure.
Rule changes worth tracking
Starting January 1, 2027, buyers using multiple points of use (MPU) certificates must renew their Comptroller authorization every two years and give each vendor a separate certificate.
