For tax year 2015 we're following national TIGERS protocol by updating our Vendor Information Form (including the title: Letter of Intent) as well as the process for providing our MeF specifications, schemas, and test packets to vendors. We're publishing the Letter of Intent on this page. However, the specs, schemas, and packets won't be available online for tax year 2015, unlike prior years.

This is the new process:

  • The vendor completes pages 6, 9, and 10 of the Letter of Intent (LOI) and submits it to the Tax Commission.
  • We review the LOI. If all is in order, we then email the MeF specifications, schemas, and test packets to the vendor.
