Frequently Asked Questions about EDI

Why should I file my return electronically?
Surveys of our current EDI users indicate they save from 50 to 75 percent of the time it normally takes to complete the preprinted return. In addition to your time, there are savings of paper and postage.

Do the due dates change for electronic filing?
Electronic filers must comply with established report due dates. Approved electronic tax filers may make their payments using the EDI payment option or continue to make their payments by Electronic Funds Transfer (EFT) or by check if you are not a mandatory EFT payor. If you transmit your tax payment with your report, you will need to complete the transaction before 2:30 p.m. (CT) on the last banking day before the due date. Your returns without payments must be completed by 11:59 p.m. (CT) on the due date. Any return transmitted after this time will be considered late and appropriate penalties will be assessed.

What kind of equipment do I need to use the free software?
The Windows versions of the software require at least a 166Mhz PC running Windows NT or higher. Minimum memory requirements are 64 MB RAM and 40 MB of hard disk space. You'll need a mouse; Internet access is necessary for electronic data interchange.

If I file by EDI, do I still need to send in paper copies of the return?
No. The confirmation number you receive indicates that we received your electronic return. Please keep a record of this confirmation number.

If I have problems filing electronically how do I get assistance?
The Electronic Reporting section of the Comptroller's office is staffed with people trained to solve a variety of software and communications problems. They can be reached every business day from 8 a.m. to 5 p.m. (CT) at 1-800-442-3453.

When is the Electronic Data Interchange System open?
The EDI system is open seven days a week, virtually 24 hours a day.

My company already uses EDI for purchasing and accounts payable. Is this the same thing?
Yes, and your EDI staff can download the EDI maps using the ANSI ASC X12 813 transaction set for a specific tax and creating their own electronic tax report.

If I file electronically, how do I pay my taxes?
There are three payment options for you.

  • EDI payment is an option offered within the 813 transaction set. Using this method meets the payment requirement if you are required to pay by EFT. If you transmit your tax payment with your report, you must complete the transaction before 2:30 p.m. (CT) on the last banking business day before the due date. Bank information is required to allow a transfer of funds (ACH Debit) to be performed electronically from your financial institution to the State Comptroller. Any payment transmitted after this time will be considered late and appropriate penalties will be assessed.
  • TEXNET or Web EFT via WebFile (for Sales & Use tax only) payment options are available. Please see TEXNET or WebFile for further information. Using this method meets the payment requirement if you are required to pay by EFT, please see Who must pay by EFT for further information.
  • Check payment is an option you may use if you are not a mandatory Electronic Funds Transfer (EFT) payor, please see Who must pay by EFT for further information. Use the payment coupon provided in our software to remit your check. Payments must be postmarked on or before the due date for the specified tax.
