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

You may use the Maryland Tax Connect Portal to file Withholding Reconciliation and Sales & Use Tax and Employer withholding returns. The service applies to filing periods in the current year and back two years.

To file electronically 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.

Year End Reconciliation Filing

Employers now have two options to file Form MW508 and W-2 information electronically.

• W-2 Bulk Upload Application - This application will allow employers and payroll providers to upload income tax withholding statements and W-2s electronically without limitation.

OR

• The File Withholding Reconciliation (MW508 and W-2 form) application allows employer to data enter up to 250 W-2s and complete the MW508.
