Sales and Use Electronic Data Interchange (EDI)

Effective July 1, 2011 taxpayers using EDI will no longer need a password to use DOR's website to submit Sales and Use returns.

What is Electronic Data Interchange (EDI)?

EDI is the electronic exchange of business documents (e.g. tax returns, invoices) from one company's computer to another company's computer in a data format that is machine-readable and follows a national standard. The North Carolina Department of Revenue (NCDOR) utilizes the 813-transaction set, called the "Electronic Filing of Tax Return Data," included in version 4010 of the ASC X12 Standards as the standard format for electronically submitting the North Carolina sales and use tax return information.

Who Can File an EDI Formatted Return?

ALL taxpayers are eligible to file Form E-500, Sales and Use Tax Return, and the breakdown schedule, Form E-536, if applicable, by uploading an EDI formatted return using the Department’s online filing and payment system.

How Do I Electronically File My EDI Formatted Sales and Use Tax Return?
  • In order to file electronically by EDI, you must complete Form NC-592, Sales and Use Tax Electronic Data Interchange (EDI) Registration. A separate Form NC-592 must be completed for each sales and use account that will use this method.  Upon approval for the EDI filing method, please allow three (3) business days after Form NC 592 has been submitted before filing your Sales and Use returns. The completed Form NC-592 should be faxed or mailed as noted on the form.
  • You will need to use NCDOR approved commercial software or software you have developed in-house to place your North Carolina sales and use tax return into the required EDI format. Please click here to access a list of software vendors who offer NCDOR approved software that can place your North Carolina sales and use tax return into the specified EDI format.
  • You will then use our online filing and payment system to upload and submit your return. Through a series of user-friendly web screens, you will be prompted to enter your NCDOR issued Sales and Use Tax Account Number and user ID. You will then reach a web screen that allows you to upload your EDI formatted sales and use tax return.
  • Monthly with prepayment taxpayers that want to file their sales and use tax returns electronically but not in an EDI format can enter their return information directly into the system.
