Filing Business Taxes Electronically

Electronic filing is the fastest way to file your business tax return. Electronic filing also allows you to pay your business taxes by direct debit. There are several ways you can file your business tax returns and reports online.

File Electronically Using Online bFile

You can file your Maryland employer withholding tax returns (Form MW506) and sales and use tax returns for free online, using bFile, if you meet the requirements below. The service applies to filing periods in the current year and two back years.

Requirements for Using bFile

You may use bFile to file employer withholding, sales and use tax, and withholding reconciliation returns. Do not send a paper form if you file using bFile.

To use bFile, you need to have:

  • a valid federal employer identification number (FEIN) or Social Security number, AND
  • a Maryland Central Registration Number (your eight-digit Maryland tax account number).

If you have not registered to file Maryland business taxes or do not have a Maryland Central Registration Number, you may register by completing the Maryland Combined Registration Online Application. You will receive the necessary information to file Maryland business taxes approximately one week after submitting your application online.
