Introduction  

Maryland law requires
                      that employers submit their annual Withholding reconciliation using 
the electronic format (to Bulk Upload or submit on media) if the total number of W2 
statements meets or exceeds 25.  We encourage all employers, regardless of the number of 
W2s, to file electronically.   
  
   annual filing deadline                                    January 31st
The                             of W2 wage/tax statements is             .  If the due date falls 
on a Saturday, Sunday or legal holiday, the statements must be filed by the next business day.   
 
The 2022 Maryland Employer Reporting of W2s Instructions and Specifications Handbook is 
designed to be used as a companion to the Social Security Administration (SSA) Publication 
No. 42-007 EFW2 Tax Year 2022.   Since many functions of the Maryland employer-reporting 
program are similar to the SSA program, this handbook highlights the special requirements of 
the Maryland program.    
 
For information concerning 1099 filing requirements refer to the 2022 Maryland Reporting of 
1099s Instructions and Specifications. 
 
Filing Requirements for W2 Wage Data   
 
Employers with 25 or more W2 forms to submit with the MW508 return must file electronically 
as described on the next page.  Filing electronically may require the generation of an EFW2-
format text file which is described in the Social Security Administration (SSA) Publication No. 
42-007 EFW2 Tax Year  2022, “Specifications  for Filing Forms  W2  Electronically  (EFW2)”.  
Additionally,  this document,  “2022 Maryland Employer Reporting of W2s Instructions and 
Specifications” will have the necessary Maryland modifications. 
 
Employers who fail to file the annual reconciliation electronically when the employer has 25 or 
more W2s, may incur a civil penalty of $100 for each violation. Failure to comply with Section 
13-706.1  of the Tax General Article, Annotated Code of Maryland  may result in the  stated 
penalty. 
 
Employers who fail to properly submit each W2 are subject to a separate violation with a civil 
penalty of $50 per  W2.  Failure to comply  with Section 13-706 of the Tax General  Article, 
Annotated Code of Maryland may result in the stated penalty. 
 
For  employers hiring  payroll companies to submit their Employer Withholding Tax and 
Employee Reconciliation, there are two reminders:   
 
  1) Please supply the payroll company with accurate FEIN and CR numbers.  You may call 
     the Comptroller’s office to verify these at 410-260-7980. 
                          
  2) If there is a change in payroll company mid-year (or anytime), clearly and in writing, 
     communicate the cut-off and start-up  dates  with both the old and the new  payroll 
     company.  Duplicate filings on a Withholding Account are a burden on the employer, the 
     employee, the payroll company and the State.  This will have an impact on receipt of 
     refunds for employees. 
                                               
                                             2022 Maryland Employer Reporting of W2 Instructions and Specifications, version 1.0 
                                                                         Page  4of   32

3 Options for Filing W2 Wage Statements Electronically  
 
Once the EFW2-format file has been generated, there are three options with which the file may 
be submitted to the Maryland Revenue Administration.  Options 1 and 2 are for tax years 2020, 
2021, and 2022. 
 • 
   Option 1:  It may be bulk-uploaded via a standardized text file at our bFile website 
 • 
   Option 2:  It can be keyed at our bFile website if less than 250 W2s. 
 • 
   Option 3:  It may be uploaded via SFTP for tax years 2019 and earlier 

Option 1 - bFile System - “W2 Bulk Upload Application” 
                         
The bFile system is our free online filing option located at www.marylandtaxes.gov 
(https://interactive.marylandtaxes.gov/Business/bFile/OSC/SelectApp.aspx).  bFile offers 
two free electronic options, the “W2 Bulk Upload Application” and the “File Withholding 
Reconciliation Application” which are described below.  Do not submit paper MW508 or W2s 
when submitting electronically. 
 
The “W2 Bulk Upload Application” allows the user (employer/payroll provider) to log on to our 
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. 
 
                                Bulk Upload Testing Application
Users are encouraged to use the                                to verify the integrity of the 
file prior to submitting their file through  the  Bulk Upload Application.   It takes seconds to 
receive feedback as opposed  to waiting 20 minutes or more  for the  production  validation 
process.  This application will indicate either an “Accepted” or “Rejected” file.  A rejected file 
will have Error codes or a description of why the file rejected. This is only a test and based on 
the feedback, the user will either use the Bulk Upload Application to upload the accepted file or 
make corrections to the rejected file and test it again. There is no limit as to how many times a 
file can be tested using the Bulk Upload Testing application. 
 
After bulk uploading your file, you must return to view your submission history 20-60 
minutes later to get official validation feedback.  
                                                    Upon successful validation of the file, all 
the records are accepted and the file will be processed for posting to your account.   Check your 
submission history even if you have used the test application described above.  Upon rejection 
of the file, all records are rejected and a listing of the errors will be provided.  For assistance 
with resolving errors for a rejected file, please reference the section ”Maryland Reject Error 
Code Definitions” further in this guide.  Please DO NOT mail in a rejected error file on media as 
                                                                                    
it will go through the same validation process and result in a failed submission.
 
Uploading Multiple Files
                         - 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.   
 
                                             2022 Maryland Employer Reporting of W2 Instructions and Specifications, version 1.0 
                                                                                    Page  5of 32

Option 2 - bFile System - “File Withholding Reconciliation (MW508 and W2 
Forms)” - Key in Your W2s 
 
The “File Withholding Reconciliation Application” allows the user (employer/payroll provider) 
to log on to our bFile system and manually enter their W2 and MW508 information. The user is 
prompted for information on each step and need only have the W2 and payroll information at 
their fingertips.  This is ideal for companies that have 250 or less W2s to report; though if 
necessary, the limit may be extended.  The validation process for this method of submitting W2s 
is ongoing as the user keys in the requested data.   A confirmation number will be assigned, and 
your submission is complete. 
 
Both  web-based  electronic options are user-friendly.  The user need only have a minimal 
knowledge of computer-based applications; instructions are clear and concise.  For questions 
concerning logon issues, extending the W2 limit and error correction (see section  “Most 
Common Errors to Avoid”),  please email  the  Processing  Control  Section,  Internet Unit at 
efil@marylandtaxes.gov or you may leave a voicemail at 410-260-7150, between the hours of 
8a.m.-5p.m., M-F. 
 
Option 3 – SFTP  - Announcement – No Longer Accepting Diskettes or CDs 
 
The Comptroller of Maryland no longer accepts magnetic media (Diskettes/ CDs). 
Please use one of the electronic submission options above.
                                                         
If you are not able to file your W2s via bFile Option 1 “W2 bulk upload” or Option 2 “key in 
your data” for Filing Year 2023 (Tax Year 2022), you may request approval to file via the 
Comptroller of Maryland secure server by either one of two SFTP (Secure File Transfer 
Protocol) methods: 
• 
  W2 Option A: Manually upload a text file to Comptroller of Maryland SFTP website  
• 
  W2 Option B: SFTP automated server to server transmission in which up to two IP address 
  will be required to be whitelisted with Comptroller, State of Maryland 
 
                SecureTransmission@marylandtaxes.gov t
You can email                         o request approval to obtain an SFTP

Electronic File Description and Record Types 
 
                                      *
Below is a description of the EFW2-format file  for bulk uploading W2s and submitting the 
electronic MW508 return. There are 4 record types:  :  RA, RE, RS and RV, each with a record 
length of 512 characters Please carefully read the detailed notes below. 
The RA record required by Maryland is identical to the RA record in the file required by the SSA 
Publication No. 42-007 EFW2 file.  The RE, RS and RV records are particular to the Maryland 
W2 file.  Your software may compile a single file that serves both federal file requirements and 
Maryland requirements.   You may open your file using Windows Notepad to see these records 
once it has been generated. 
 
RA - Submitter Record
                            (Same record layout as SSA Publication No. 42-007 EFW2 Tax Year 
                            2022)   
RE - Employer Record
                            (Modified record layout description)  
 
RS - State Record
                            (Modified record layout description) 
 
RV - Total Record
                            (Modified record layout description)  
 
*
 The electronic file that you create may be opened and viewed using Windows Notepad.  It is 
helpful to click on the “View” menu header and check the “Status Bar” so that the column/line 
numbers appear at the bottom, right corner of the screen, below the left-right scroll bar.  Also, 
click on the “Format” menu header to make sure Word Wrap is NOT checked. 
Note:  
 
 • 
       Multiple companies can be submitted in one file. If submitting for multiple companies, 
       repeat each set of record types RE, RS and RV, in this sequence for each company you 
       are submitting, with only a single RA record at the beginning of the file. 
 
 • 
       Data must be uppercase letters in ASCII.   
 
 • 
       File should include record delimiters (CR- Carriage Return followed by LF – Line Feed). 
       Each record delimiter must consist of a carriage-return/linefeed (CR/LF) and placed 
       immediately following position 512. Do not place a record delimiter before the first 
       record (RA) of the file. This is the same as stated in SSA Publication No. 42-007 EFW2 
       Tax Year 2022, section 7.3 Data Requirements. 
        
 • 
       Each record type (RA, RE, RS, RV) starts on a new row.  
        
 • 
       Electronic files submitted by bulk upload may be compressed using  7-Zip, PKZIP or 
       WinZip.  Do not encrypt the submission with a password.

Third-Party Sick MW508 Reporting – How to Set Record Indicators 
 
This is a synopsis of the electronic file Field Descriptions that are relevant to a MW508 file 
submitted by a third-party sick vendor.  These Field Descriptions are taken from the Record 
Formats for RE, RS and RV records and have been placed here for reference.  To check these fields 
in your EFW2 file, open the file in Windows Notepad; Under the in View menu header, check 
Status Bar so that you can find the field by column number and row number. 
 
Keep in mind that you must use this third-party Field Description ONLY IF   you are the paying 
agent.  In this case the RE, RS and RV records should reference the Maryland Withholding Account 
(FEIN/CR) under which withholding taxes were paid. 
 
The RA record has no Field Descriptions specific to third-party withholding agents; submitters 
should follow the SSA’s Specifications for Filing Forms W2 Electronically to reflect the submitter’s 
Federal Employer Identification Number FEIN). 
 
The RE record fields:   
 
         Field  7should have a “ ”.1
         Field 8-16 should indicate the FEIN of the paying Agent (withholding tax payments must have 
         been made to this FEIN and it must be an account registered with the State of 
         Maryland). 
         Field 17-25 is for the employer FEIN (withholding tax payments must not have been made to 
         this FEIN but made on behalf of this FEIN). 
                  Field221 should have a “1”.
