General Information 
These are the instructions for filing EFW2 or EFW2C information to the District of 
Columbia (DC) Office of Tax and Revenue (OTR) via electronic filing using the Social 
Security Administration (SSA) Specifications for Filing Forms EFW2 or EFW2C and 
your reporting requirement is 25 or more W-2s. 

Visit SSA.gov for EFW2 and EFW2C specifications. 

OTR paper filers are being offered a faster and more convenient way to create and 
transmit EFW2 and EFW2C (correction) wage reporting electronically. Electronic filing 
eliminates the outdated manual paper and magnetic media processes. The same file 
that you transmit to SSA can now be transmitted to the District of Columbia, with a 
required RS record for DC. OTR does not offer any support of AccuWage or any other 
product you use to generate your EFW2/EFW2C submissions. 

DO NOT send paper or PDFs of W-2s or W-2Cs if you have submitted your file(s) 
electronically or used the online data entry system. These are for your records. 

All submitters must register to create your logon ID through our web portal, 
MyTax.DC.gov whether you are an employer, a payroll provider, a preparer, or enrolled 
agent. Please visit us online at https://mytax.dc.gov/. If you need assistance with 
obtaining a logon ID or authorizing a third-party to submit the EFW2 or EFW2C, please 
review the tutorials/FAQs on the web portal. Instructions are also included in this guide. 

Filing 

Electronic Filing 
You must file electronically if you are filing 25 or more W-2s or W-2Cs via the web 
portal, MyTax.DC.gov. 

Paper 
Even if you are a small business filing fewer than 2 5W-2s, in lieu of sending paper, 
OTR encourages you to file electronically using our online manual data entry application 
or file upload method. 

Filing Options 

Option 1  Manual Online Entry (Small Business) 
Filing 24 or fewer W-2s? It's easy to file electronically with online data entry. This option 
is available for small business employers or preparers and allows the preparation and 
submission of up to 2 4W-2s per report over a secure internet service.

                                                                               3 | P a g e

The ability for smaller to medium sized business to manually key in all the information on
the W-2s/W- 2Cs and forgo the file creation process and submission. 

Option 2  Bulk File Submission (Larger Businesses) 
Filing 25 or more W-2s or using third-party bulk filing? It's easy to file electronically with 
W-2 File Upload. This electronic filing option is available for larger businesses and third- 
party bulk filers.  Using approved software that generates the correct SSA formats, the
bulk file submission allows an employer/payroll provider or others to electronically
submit their W-2s/W-2Cs.

Option 3  Multiple Employer Submissions (Third Party Bulk Filers) 
This is the same process as option 2, the difference being that a Third-Party can submit 
files containing multiple employers. The mechanics of submitting these Multi-Employer 
bulk submissions is the same as the Bulk File Submission. 

EFW2/EFW2C Data Requirements and File Acceptance 
Please refer to the SSA handbook to obtain additional information regarding data 
requirements and file acceptance to eliminate file rejection due to errors. The 
submissions must be in the order listed below, even if the record is defined as optional. 
Listed below are the EFW2 or EFW2C record requirements for file creation of records to 
be submitted to the OTR: 

• RA–Submitter Record (Required)
• RE–Employer Record (Required)
• RW–Employee Wage Record (Required)
• RO-Employee Wage Record (Optional)
• RS-State Wage Record (Required)
• RT-Total Record (Required)
• RU-Total Record (Optional)
• RV-State Total Record (Optional)
• RF-Final Record (Required)

                                                                                4 | P a g e

Employer/Employee Record Information 

Submitters’ Information 

Record Length 
All employer records must adhere to the required record length for both EFW2 and 
EFW2C as follows: 

• Electronic File EFW2 – 512 bytes (each record)
• Electronic File EFW-2C Correction – 1,024 bytes (each record)

Each record must terminate with a carriage return (at the end of each row). 

RA Submitter Record 
It is imperative that the submitter's telephone number and e-mail address be entered in 
the designated positions. Failure to include correct and complete submitter contact 
information may result in OTR rejecting your file submission. 

RE Employer Record 
Be sure to enter the correct tax year in the Employer Record (e.g., YYYY). 

Be sure to provide the Employer Name in the Employer Record. 

Employment Code in the Employer Record is optional for DC EFW2 reporting. (Note: 
Please ignore it if your EFW2 file fails the AccuWage validation due to a missing value 
in this field or any related validation against this field.) 

RW Employee Wage Record 
Be sure to enter the correct amount of employee wages. 

RS State Wage Record 
The RS Record is required for DC wage reporting. 

RT Total Record 
Be sure the totals values match throughout the file. 

RF Final Record 
Be sure each data file submitted is complete. 

RO, RU & RV Records 
These records are optional and do not contain wage reporting data relevant to DC. 

                                                                            5 | P a g e

Social Security Number and Name Verification 
We also recommend that you also visit the SSA website for additional information on 
how to validate employee names and social security numbers. The OTR also 
recommends that you verify all names and social security number (SSN) before you 
submit your EFW2/EFW2C file. This can speed up the processing of your submissions. 
(Note: Correct names and SSNs on the W-2 and W-2C wage reports are the key to the 
successful processing of your annual wage report submission.) 

• OTR does not allow employers to submit W-2 or W-2C wage reports that contain 
  an invalid or impossible SSN, except that SSA and OTR temporarily accepts all 
  zeros as the SSN. Employers are expected to enter the SSN shown on the 
  employee's Social Security card.
• If you do not have an SSN when your W-2 report is due, complete the SSN field 
  by entering all zeros in locations 3-11 of the RW (employee wage record). The all 
  zeros should also be entered in the correct location (10-19) of the required RS
  (state wage record).

NOTE: Valid ranges for social security numbers are as follows: 

  o      001-01-0001 through 665-99-9999
  o      667-01-0001through 899-99-9999
  o      May not begin with 666 or 9
  o      When the SSN contains zeros in positions 4-5, the SSN is a test SSN and
         it will be rejected
  o      When the SSN contains zeros in positions 6-9, it will be rejected

Upload File Specifications 
Files must be in the format .txt or .zip. Files that are 200MB (uncompressed) or larger 
will be rejected. 

The maximum number of file attachments (less than 200MB) per file type is five (5). 

For example: 
File 1: 8.50 MB 
File 2: 90 MB 
File 3: 60 MB 

More than five attachments can be submitted in an additional request. 

                                                                          6 | P a g e

Recommendation 

Use a text editor, such as Notepad++, to verify that the length of each line follows the requirements (W- 
2: 512 W-2C: 1,024) .Look for extra spaces at the end of a record or an extra blank line added to the end 
of the final record.

NOTE: At any time, the submission can be paused with “Save and Finish Later” button 
in the bottom left. By pressing this, the Portal will save the submission but not submit it 
allowing the user to come back later and finish the submission. 

Manual submission of W-2 or W-2C 
If the option chosen was “Manually key individual forms,” verify the information is 
correct, as this will be automatically pulled into each individually keyed W-2/W-2C.

                                                                                         11 | P a g e
