Submitting files

Maryland accepts Prior year filing for 2020 and later.
All corrected and amended W2Cs and MW508s must be submitted on paper

Maryland is no longer accepting W2 text files via SFTP, as all tax years will be accepted on the new web portal “Maryland Tax Connect”.   Payroll System will prepare the properly formatted file(s) for you in Steps 4 and 5 of the W-2 E-filing module, as well as providing you a link to the new “Maryland Tax Connect” (in Step 5), where you will then upload your file(s). 

Maryland has 3 types of User Accounts for Bulk filing Withholding Annual Reconciliation of W2/1099/508s via the new portal MDTaxConnect

  • Tax Business Administrators (automatic access to bulk filing)
  • Authorized Users (Tax Business Administrator or Maryland Taxpayer Services Customer Service Representative taxhelp@marylandtaxes.gov must grant access for bulk filing)
  • Transmitter Users (file on behalf of multiple employers: must Register for access to bulk file)

When we did the demo, we miss including a User Guide on how the Tax Business Administrator can grant MdTaxConnect Authorized users access to bulk filing of Maryland W2/1099/508s. 

See attached “Authorized User Guide for bulk filing” on how Tax Administrator can grant this access to their Authorized Users.  Please feel free to share with your members.

Also,  Maryland will be sending an email out this week alerting mdtaxconnect users of this Authorized User guide is available at https://www.marylandtaxes.gov/mdtaxconnect/ click on User Guides and select Authorized User Guide For Bulk Filing

Submitting FIles

There are three options for filing electronically W2/MW508 to Maryland Revenue Administration.

• Option 1: As a Maryland Tax Connect User with a withholding account you may upload a properly formatted text file (Payroll System supports by properly formatting when you create your file in Step 4 of W-2 E-filing module).

All Maryland Tax Connect Users who have a withholding account, can bulk file .txt file(s) (prepared by Payroll System in Step 4 of W-2 E-filing module).  Your file should only contain the employers of withholding accounts that the Maryland Tax Connect user has access.

The new Bulk Filing and TEST instructions will be available no later than mid November 2024 online at https://www.mdtaxconnect.gov/ web portal under Quick Links\User Guides and Tutorials.

• Option 2: Register as a Transmitter Bulk Filer at the web portal “Maryland Tax Connect” to upload a properly formatted text file (prepared by Payroll System in Step 4 of W-2 E-filing module). 

If a payroll provider or a third party filing on behalf of employer(s) in which you do not have a Maryland Tax Connect User account, you will need to first register as a Transmitter user creating a new Transmitter user-id and password.

Register as a Transmitter user. The Transmitter User Registration instructions will be available no later than mid November 2024 online at https://www.mdtaxconnect.gov/ web portal under Quick Links\User Guides and Tutorials.

There will be new Transmitter bulk filing Production and TEST instructions available no later than mid November 2024 online at https://www.mdtaxconnect.gov/ web portal under Quick Links\User Guides and Tutorials.

Option 3: W2s/MW508 can be keyed manually via our new web portal “Maryland Tax Connect” if less than 25 W2s.

The option to key in W2’s and MW508 will require a registration as a Maryland Tax Connect user via the new “Maryland Tax Connect” web portal. The Maryland Tax Connect User Registration instruction is located online at the new web portal “Maryland Tax Connect” site. Under ‘Quick Links’ click on User Guides and Tutorials.

If you already have a Maryland Tax Connect user-id to file Maryland withholding taxes (MD Form 506), then this same Maryland Tax Connect user-id can be used to log in to key-in your W2(s) and MW508 Annual Reconciliation.

It is the user’s responsibility to know their state’s rules, requirements and how to navigate their website(s).
