What is the Maryland franchise tax?

Maryland has two franchise taxes: a public service company franchise tax and a financial institution franchise tax. The public service company franchise tax applies to utilities engaged in telephone business or in the transmission, distribution, or delivery of electricity or natural gas in Maryland. 

The financial institution franchise tax, on the other hand, applies to certain banks and similar institutions. Most ordinary businesses are not subject to either franchise tax.

The State Department of Assessments and Taxation (SDAT) administers the public service company franchise tax. Because it is measured by receipts and deliveries rather than profit, companies may owe this tax even in loss years. Maryland has detailed information about franchise taxes on SDAT's Franchise and Public Utilities page.

For telephone companies, the tax is 2% of taxable Maryland gross receipts. For electric and gas companies, the tax includes 2% of taxable Maryland gross receipts plus additional charges based on kilowatt-hours of electricity and therms of natural gas delivered for final consumption in Maryland.

Who must file Maryland’s franchise tax?

Maryland's public service company franchise tax applies to companies engaged in a telephone business in Maryland or in the transmission, distribution, or delivery of electricity or natural gas in the state.

A separate financial institution franchise tax (7% of taxable net earnings) applies to certain banks and financial institutions under Tax-General Title 8, Subtitle 2.

Most other businesses do not pay a Maryland franchise tax. Regular C corporations pay Maryland's flat 8.25% corporate income tax on state-apportioned income instead. LLCs and S corporations generally operate as pass-through entities and pay tax at the owner level, though Maryland offers an elective pass-through entity tax.

Maryland franchise tax filing requirements

Public service company franchise tax is reported on separate SDAT franchise tax forms, not on Form 1 (the Annual Report and Business Personal Property Return).

Electric and gas companies file:

  • Form 11 (Public Service Company Franchise Tax Return)
  • Form 29EW (Declaration of Estimated Franchise Tax)
  • Form 29E (Estimated Tax Payment Vouchers)
  • Form 17 (Public Utility Operating Property Return)

Telephone companies file:

  • Form 11T (Public Service Company Franchise Tax Return for Telephone Companies)
  • Form 29EW, Form 29E, and Form 17

The Annual Report and Business Personal Property Return (Form 1) is a distinct filing that applies to most business entities and is not the franchise tax return.

Additional state taxes

Beyond the franchise tax, Maryland businesses face several other tax obligations that vary by entity type and business activities. This includes:

  • Corporate income tax
  • Pass-through entity tax
  • Sales and use tax
  • Vehicle excise tax
  • Short-term rental tax
  • Employment taxes
  • Property taxes

Extensions and amendments

Form 1 (Annual Report) is due April 15 each year. Businesses may request a 60-day extension by submitting an online extension request through SDAT's website on or before April 15. Extension requests must be made online; paper extensions are not accepted. There is no separate "expected tax" payment with the Form 1 extension.

Public service company franchise tax returns (Form 11 and Form 11T) are due April 15 following the calendar year and cannot be extended.

For amendments to Form 1, mark the "AMENDED RETURN" checkbox, attach schedules showing corrected figures, and include payment for additional tax and interest due. No separate amendment fee applies.
