  1. What is e-File Transmission?

    It is a secure process developed by the Wisconsin Department of Revenue (DOR) for employers and/or their representatives to transmit Forms WT-6 and estimated payments to DOR via an electronic file over the Internet. There are two methods offered for e-File transmission:

    1. HTTPS Post method can be done via a web page or a command line script. The response contains a receipt number for the transmission.
    2. Secure FTP method requires an ID and password and special client software. Please contact DOR to discuss details.
  2. What are batch payments?

    Batch payments allow payroll service providers to submit a file with return and payment information for multiple customers.

  3. If I make a batch payment for withholding tax, do I need to file Form WT-6?

    No, there is enough information in the batch payment file to constitute the filing of Form WT-6, as well as information to initiate an ACH debit payment authorization.

  4. I am a payroll service provider, do I need to "enroll" each customer for e-filing/paying?

    No, there is no "enrollment" requirement to submit returns/payments on behalf of your clients. You should retain information signed by your client authorizing you to file returns and make ACH debit payments on their behalf.

  5. I am a payroll service provider, can I file and pay for multiple customers and make one ACH payment?

    Yes, this is called the "Single Debit" method in the instructions.

  6. I am a payroll service provider, can I send a file with multiple payments, but with an ACH debit from each customers account?

    Yes, this is called the "Multiple Debit" method in the instructions.

  7. How do I get started?

    Carefully review the information and instructions at revenue.wi.gov/eserv/wt-6/index.html

  8. How do I file timely?
    • Transmit returns without EFT payment by 11 PM on the due date.
    • Transmit returns with EFT payment by 4 PM CST at least one business day prior to the due date.

    If the due date falls on a weekend or bank holiday, the due date is extended to the next business day.

  9. How do I change a filed return and/or payment?

    Electronic returns cannot be recalled or intercepted after transmission. Changes to any entries after a return has been acknowledged must be retransmitted.
