Submitting files

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

The “W2 Bulk Upload Application” allows the user (employer/payroll provider) to log on to the bFile system and upload a text file or a zipped text file, compiled in the required EFW2 format. The file may contain W2/MW508 information for multiple employers (see Electronic File/Records). The W2 Bulk Upload Application will automatically validate the data in the file. A confirmation number will be assigned once the valid file is uploaded. Files that are rejected will receive error codes with a description of the error.

Before you process a file you must complete Form MW508 Located in CFS Payroll System under ''W-2/1099 Information Returns'' and save the form to process W-2's for Maryland. The RV record in the file contains all of the data from the MW508. When you process the file you will be given the option to select a saved MW508. Do not include the paper MW508 with your submission as the RV record is considered the electronic version.

It is recommended that the file is transmitted after you process it. The file contains date field in the file as the date that the file was transmitted to Maryland. If you choose to submit the file on a different day then you should ''Reset'' the file and ''Create'' the file on the day that you submit it.

The Maryland Central Registration Number is an eight-digit number assigned by Maryland when you open a state withholding account. The number is located under the label "REGISTRATION NBR" in the coupon books sent to each employer.

After bulk uploading your file, you must return to view your submission history from 20-60 minutes later to get official validation feedback. Upon successful validation of the file, all of the records are accepted and the file will be processed for posting to your account.

A user may upload multiple files using the same logon ID but must wait until after the validation process has taken place to submit the next file.

W2 Bulk Upload Testing Application in bFile The bFile Services website provides a Test Link “W2 Bulk Upload Testing Application” to check your file for errors ( https://interactive.marylandtaxes.gov/Business/bFile/OSC/SelectApp.aspx ). If the file is rejected upon validation, the associated error message will report the line number and position
