    Preparing to File

    3. Validate files using AccuWage (see AccuWage Validation topic)
    4. Review and print the AccuWage validation report showing no errors
    5. Have your SSA login credentials ready

    Timing Recommendations

    • Filing deadline: January 31st
    • Recommended timing: Wait 2-3 weeks after year-end before filing
    • Reason: Allows time for year-end adjustments, bonus processing, and corrections to 4th quarter Form 941

    Filing Process

    Step 1: Log In to SSA

    1. Go to: https://www.ssa.gov/bso/bsowelcome.htm
    2. Enter your User ID
    3. Enter your password
    4. Click Login

    Step 2: Access Upload Function

    1. Click the Upload Formatted Wage File tab
    2. Review any important notices or announcements
    3. Click Submit/Resubmit a Formatted Wage File

    Step 3: Select File Type

    1. Click Continue on the initial screen
    2. Ensure New W-2s/W3 is selected (this is the default for annual filing)
    3. Click Continue

    Note: Only select other options if you're filing corrections (W-2c) or resubmitting after a rejection.

    Step 4: Upload File

    1. Click the Browse button
    2. Go to your \PAYSOFT\PROPAY26 folder
    3. Locate the W-2??????.TXT file
      • The ?????? represents your client identifier
      • Example: W-2ABC123.TXT
      1. Select the file
      2. Click Open
      3. Verify the correct filename appears
      4. Click Submit

      Step 5: Confirmation

      1. Wait for SSA to process your file (may take several seconds)
      2. Review the confirmation screen
      3. Print the confirmation receipt
      4. Note the confirmation number
      5. Save or file the receipt with your tax records

      Important: The confirmation receipt is your proof of filing. Keep it for at least 4 years.

      What Happens After Submission

      SSA Processing

      After you submit your file:

      1. SSA receives and logs your submission
      2. SSA performs additional validation checks
      3. SSA processes the wage data
      4. SSA may send notifications if issues are found

      Confirmation vs. Acceptance

      • Confirmation receipt: Proves you submitted the file
      • Acceptance: SSA has fully processed and accepted your data

      Most files are accepted immediately if they pass AccuWage validation. However, SSA may identify issues during processing.

      If SSA Rejects Your File

      1. You will receive notification of the rejection
      2. Review the rejection reason carefully
      3. Make corrections in ProPay
      4. Generate a new W-2 file
      5. Revalidate with AccuWage
      6. Resubmit through SSA Business Services Online

      Multiple Client Filing

      If you're filing for multiple clients:

      Option 1: Combined File

      Create one file containing multiple clients:

      1. Select all clients when creating the W-2 file in ProPay
      2. ProPay creates a single file with all client data
      3. Submit the combined file to SSA

      Option 2: Separate Files

      Create and submit individual files for each client:

      1. Create W-2 file for first client
      2. Submit to SSA
      3. Repeat for each additional client

      Tip: Combined files are more efficient for high-volume filers.

      W-2 File Format

      ProPay creates files in SSA's MMREF-1 format, which includes:

      Records Included

      • RA Record: Submitter record (your information as the filer)
      • RE Record: Employer record (client company information)
      • RW Record: Employee wage record (one for each employee)
      • RS Record: State wage record (state tax information)
      • RT Record: Total record (totals for each employer)
      • RF Record: Final record (grand totals for entire submission)

      File Naming Convention

      ProPay names files as: W-2??????.TXT

      Where ?????? is typically:

      • Client code or identifier
      • Numeric sequence
      • Tax year indicator

      State Filing Coordination

      The W-2 file submitted to SSA includes state wage information in the RS record:

      • Employee's wages subject to state withholding
      • State tax withheld for the year
      • Employer's state ID numbers
      • Local tax information (where applicable)

      State Information Sharing

      Many states have agreements with the federal government to exchange W-2 information. Filing with SSA may fulfill your state requirement, but:

      • Always verify your state's specific requirements
      • Some states require additional or separate filing
      • Check state deadlines (may differ from federal January 31st deadline)

      See the "State W-2 Filing" topic for state-specific guidance.

      Troubleshooting

      Cannot Log In

      Problem: Login credentials don't work

      Solutions:

      • Verify you're using the correct User ID (not email address)
      • Check that Caps Lock is off
      • Use the Forgot Password link to reset
      • Confirm you completed registration and received confirmation

      File Upload Fails

      Problem: Upload times out or fails

      Solutions:

      • Check your internet connection
      • Verify the file format is correct (W-2??????.TXT)
      • Ensure file isn't corrupted (revalidate with AccuWage)
      • Try uploading during off-peak hours (avoid early morning or near deadlines)
      • Try a different web browser

      Wrong File Type Selected

      Problem: Selected W-2c instead of W-2, or vice versa

      Solution:

      • Start the upload process again
      • Carefully select the correct file type
      • New W-2s/W3 is for original annual filings
      • W-2c is only for corrections to previously filed returns

      Confirmation Receipt Won't Print

      Problem: Cannot print the confirmation

      Solutions:

      • Use your browser's print function (Ctrl+P or Cmd+P)

      • Take a screenshot as backup
      • Note the confirmation number manually
