Submitting files

Maryland accepts Prior year filing for 203 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

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

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

Option 1: Maryland Tax Connect User

All Maryland Tax Connect User who have a withholding account, can bulk file an IRS SSA Publication 42-007 EFW2 .txt file that is in the modified Maryland standard format. The EFW2 .txt file should only contain the employers of withholding accounts that the Maryland Tax Connect user can access. The Bulk Filing and TEST instructions are available online at www.mdtaxconnect.gov web portal under Quick Links, select User Guides and Tutorials, scroll down to the ‘User Guides’ section, choose the W2/1099 Bulk Upload Guide option and page 11 has the testing instructions.

If you have zero wages for the tax year, see ‘Option 3’ below

Option 2: Transmitter Bulk Filer 

If a payroll provider or a third party is 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 for TY2025 are available online at www.mdtaxconnect.gov web portal under Quick Links\User Guides and Tutorials.

Scroll down to User Guide section and click on Transmitter User Registration Guide.

If you have zero wages for the tax year, see ‘Option 3’ below

Option 3: Key-in W2s and MW508.

Register as a Maryland Tax Connect user. The option to key in W2’s and MW508 will require a registration as a Maryland Tax Connect user via the “Maryland Tax Connect” web portal. The Maryland Tax Connect User Registration instruction is located online at the web portal “Maryland Tax Connect” site. Under ‘Quick Links’ click on User Guides and Tutorials, scroll down to the ‘User Guides’ section, choose the Maryland Tax Connect Registration and Linking Tax Account(s) Guide.

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.

If you are responsible for keying W2(s)/MW508 and are not the primary “Maryland Tax Connect” user for filing the withholding taxes, you may require additional authorization from the primary “Maryland Tax Connect” user to grant you access to the business entity. Please reference the registration instructions for “Maryland Tax Connect users” under ‘Quick Links’ click on User Guides and Tutorials, scroll down to the ‘User Guides’ section, choose the Adding an Authorized User Guide.

When keying in W2(s)/MW508, user(s) need only have the W2/MW508/payroll information at their fingertips. This is ideal for companies that have less than 25 W2s to report. After submission, a confirmation number will be assigned, and your submission is complete.

The ability to report $0 wage and/or zero MD withholding will only be supported via MDTaxConnect portal Key-in application. You will be able to manually key in zero MW508’s for tax year 2025.
