Attention Forms/Software Developer

  • You should follow the requirements provided when creating North Carolina substitute tax forms
  • North Carolina prohibits the use of the Web and Web-fill versions in software tax products.
  • If your software company has plans to make system enhancements/technology upgrades, you are advised to contact the Department regarding your software vendor forms. Changes to your system may require additional sample forms to be submitted for testing to ensure your product continues to coincide with already approved software developer versions. Please contact Vendor Support at 919-754-2625 or email
