How to Form a Maryland Corporation

Want same-day in-person service? Drop your documents off at SDAT's dropbox by 10 AM and pick up your approved filing by 3:45 PM. If you're planning ahead, standard processing works fine.

What to do after Maryland approves your articles of incorporation

Getting SDAT's approval is progress, not the finish line. But, if you skip a post-formation step, you'll run into trouble, whether that's a rejected bank account application, a gap in your tax registration, or loss of good standing with SDAT. Work through these in order since each one builds on the last.

Get an EIN from the IRS

An employer identification number (EIN) is your business' federal tax ID assigned by the IRS. You'll need one before opening a business bank account, hiring employees, or registering for state taxes with the Comptroller.

You can apply directly on the IRS website for free or use LegalZoom’s EIN service. The IRS typically issues your EIN immediately upon submission.

Register with the Maryland Comptroller for state taxes

Once you have your EIN, register your corporation with the Maryland Comptroller’s online portal, Maryland Tax Connect, to open the tax accounts your corporation needs, including income tax and, if you sell taxable goods or services, a sales and use tax account.

If you’re not sure exactly what taxes your corporation may need, reach out to the Maryland Comptroller’s office or work with a tax professional.

File your Maryland annual report and business personal property return with SDAT

Maryland domestic stock corporations file Form 1, the Business Entity Annual Report, each year by April 15. The filing fee is $300. The personal property return portion is required only when the corporation owns, leases, or uses qualifying Maryland personal property or maintains a trader’s license. SDAT allows a requested 60-day filing extension.

Miss this deadline, and you risk losing your corporation's good standing, which can hurt your ability to get financing, licenses, or legal recognition down the road. File through Maryland Business Express, and SDAT marks your annual report as filed the same day you submit online.

Get Maryland business licenses through your local Clerk of the Circuit Court

Not every Maryland corporation needs a business license, but plenty do, and the process runs through an agency most owners don't expect: the Clerk of the Circuit Court in the jurisdiction where your business operates.

Finish your SDAT registration and Comptroller registration first; by this point, you've already checked both boxes. Whether you need a license, and which kind, comes down to your industry and county. LegalZoom's service gives you a personalized report on exactly which licenses, permits, and registrations your business needs, along with direct links to the applications.

Hold your organizational meeting and issue stock

With your external filings squared away, turn your attention inward. The organizational meeting is your board's first formal gathering, and it covers the foundational decisions that shape how your business runs.

At this meeting, the board typically adopts bylaws, elects officers, authorizes stock issuance to initial shareholders, and opens the corporate bank account. None of this is optional. Courts and lenders look at this record when they need proof that you’re running your corporation as a separate legal entity, not just a name on a filing. Keep written minutes and store them in your corporate records book.

Elect S corporation tax status (if applicable)

Want your Maryland corporation taxed as an S corp instead of a C corp? File IRS Form 2553 with the IRS, not SDAT. The S corp election lives entirely at the federal level; it's not a state filing.

To apply the election to a tax year, file Form 2553 no more than two months and 15 days after the beginning of that tax year, or during the preceding tax year. An S corporation may have different Maryland income tax and withholding obligations, but the election does not replace the corporation’s SDAT filings or annual Form 1 requirement.

Common mistakes that delay Maryland corporation filings

Rejected articles of incorporation can be corrected and resubmitted within 60 days at no extra cost. But, given SDAT's standard 6-8 week processing window, a rejection can push your launch back by months.

Here are some of the most common reasons articles would be rejected:

• Name is missing a corporate designator. Your name needs "Incorporated," "Corporation," "Limited," "Company," or an accepted abbreviation.
• Name isn't distinguishable from an existing Maryland entity. Run a name search through Maryland Business Express before filing.
• Resident agent information is incomplete or the agent has not consented. The articles must identify a qualifying resident agent, provide a physical Maryland address, and include the agent’s consent.
• Resident agent address is a P.O. box. The articles must list a physical Maryland street address for the resident agent.
• Wrong fee or payment. Checks may be payable to the State Department of Assessments and Taxation or SDAT.

Maryland corporation FAQs

How long does SDAT take to process Maryland articles of incorporation?

SDAT’s stock-corporation instructions estimate six to eight weeks for standard review. Expedited review generally takes seven to 10 business days for an additional $50. Same-day service is available for qualifying online or paper filings for an additional $325 or $425, respectively.

Can I be my own resident agent for a Maryland corporation?

Yes, as long as you're a Maryland resident with a physical Maryland address who's willing to accept the role. If you’re not a Maryland resident, you can't serve as your own resident agent and will need to appoint someone who qualifies or hire a commercial agent service. One thing to know: Your address becomes public record once it's listed as the resident agent address, which is why a lot of owners use a commercial agent to keep their home address private.

Do I need a lawyer to form a Maryland corporation?

No, Maryland law doesn't require an attorney to file articles of incorporation with SDAT. Plenty of people file on their own. That said, if you've got multiple founders, outside investors, complicated equity arrangements, or industry-specific licensing to deal with, a lawyer can help set things up right from day one and save you from expensive fixes later. For a straightforward single-founder formation, a formation service or a direct SDAT filing works fine and costs less.

How do I elect S corporation tax status for a Maryland corporation?

File IRS Form 2553 with the IRS. To apply the election to a tax year, submit the form no more than two months and 15 days after that tax year begins, or during the preceding tax year. The election may change the corporation’s Maryland income tax and withholding obligations, but it does not replace SDAT filings or the annual Form 1 requirement.
