One statewide rate applies with no local add-ons, which makes Maryland invoices simple — the harder question is whether a given digital product or service is taxable.
Maryland sales tax rates
Maryland charges sales and use tax at 6.00% statewide. There are no local add-ons, so one rate applies across the state.
| Statewide rate | 6.00% |
|---|---|
| Average local add-on | 0.00% |
| Highest local add-on tracked | 0.00% |
| Average combined rate | 6.00% |
| Rank by combined rate | 38th highest of 50 states |
Local rates in Maryland
Maryland does not allow local sales taxes. The 6.00% state rate applies in every city and county, which removes the address-lookup problem that sellers face in most other states.
Special rates can still apply to particular categories — lodging, prepared food, vehicle rental and similar — so check the category as well as the rate.
What to put on a Maryland invoice
- The word Invoice and a unique invoice number
- Your business name, address, email and phone
- The customer's legal name and Maryland billing address
- Invoice date and a calendar due date, not just Net 30
- A line for each item or service with quantity and rate
- Any sales and use tax shown on its own line with the rate used
- How to pay — ACH details, check payee or a payment link
- A purchase order number where the customer issued one
- Your state tax permit number where the state expects it
- A reference to an exemption or resale certificate on exempt sales
Registering and filing in Maryland
Sellers with a physical presence in Maryland — premises, staff, stock or regular on-site work — generally register with the Comptroller of Maryland before their first taxable sale. Remote sellers register once their sales into the state cross the state's economic nexus threshold.
Filing frequency is set by the state and usually depends on how much tax you collect: larger collectors file monthly, smaller ones quarterly or annually. The Comptroller of Maryland sets and notifies your frequency — do not assume it stays the same as your volume grows.
We deliberately do not publish thresholds, filing deadlines or penalty amounts on this page. Those numbers change, and the only copy worth relying on is the one on the state's own site, linked below.
Exempt sales and certificates
Resale, manufacturing, non-profit and government exemptions all exist in Maryland, and each one depends on a valid certificate from the buyer, not on the buyer's word. Collect the certificate before you issue a zero-tax invoice.
Reference the certificate on the invoice rather than silently leaving tax off. A tax line of $0.00 with a note explaining why is far easier to defend in an audit than an invoice with no mention of tax at all.
Example Maryland invoice
A contractor billing a Maryland customer for equipment and labour, showing how the tax line sits under the subtotal.
| Description | Qty | Rate | Amount |
|---|---|---|---|
| Equipment supplied and installed | 1 | $1,600.00 | $1,600.00 |
| On-site labour | 8 | $100.00 | $800.00 |
| Subtotal | $2,400.00 | ||
| Maryland sales and use tax at the 6.00% average combined rate | $144.00 | ||
| Total due — Net 30 | $2,544.00 | ||
Common Maryland invoicing mistakes
Charging tax without being registered
Collecting sales and use tax before you are registered creates a liability with no account to remit it to, and the customer cannot reclaim it.
Assuming services are treated like goods
Taxability of services varies widely between states and within them. Confirm the treatment of your specific service with the Comptroller of Maryland rather than copying what a supplier in another state does.
Leaving the due date implied
Write both the terms and a calendar date. In a corporate payment run, an ambiguous due date always resolves in the payer's favour.
Filing the certificate nowhere
Exemption and resale certificates are what justify a zero-tax invoice years later. Store them alongside the invoice, not in an inbox.
Sending to your day-to-day contact only
Your contact commissioned the work; a different inbox pays for it. Ask for the accounts payable address at the start.
Maryland invoicing FAQs
What is the sales tax rate in Maryland?
The statewide rate is 6.00%. Local jurisdictions add 0.00% on average and up to 0.00% where local taxes are highest, giving an average combined rate of 6.00% — the 38th highest average combined rate in the country. Figures are from the Tax Foundation's midyear 2026 table; always confirm the rate for your customer's exact address with the Comptroller of Maryland.
Do I have to charge Maryland sales and use tax on my invoices?
Only if you are registered in Maryland and what you sell is taxable there. Registration is triggered by physical presence or by crossing the state's economic nexus threshold for remote sellers. Taxability of services in particular varies, so check the position for your specific work with the Comptroller of Maryland before adding a tax line.
Does Maryland have local city or county sales taxes?
No. Maryland has no local sales taxes, so the 6.00% state rate applies everywhere in the state.
Is a specific invoice format required in Maryland?
There is no prescribed commercial invoice template in Maryland. What matters is that the invoice identifies both parties, describes the supply, shows the amount due, shows any sales and use tax separately, and can be reconciled with your returns and records.
Where do I register for Maryland sales and use tax?
Through the Comptroller of Maryland, which runs registration, filing and rate lookups for Maryland. Its website is linked in the official sources section on this page.
Can I invoice a Maryland customer from another state or country?
Yes — the invoice itself is the same document. The question is whether your sales into Maryland create a registration obligation there. Remote sellers can be required to register once they exceed the state's economic nexus threshold, so track your sales by state.
