Guidelines for Substitute Oklahoma Tax Forms:
Letter of Intent
Complete your Letter of Intent and mail it to the Oklahoma Tax Commission. We will file your letter and register your identification code. This identification code is of your choosing, and must appear in the lower left corner on all of your substitute forms. If your code is like or too similar to another vendor, we will notify you so you can choose another code. You may use your NACTP vendor code if you wish.
Note: The Oklahoma Tax Commission does not review or approve the logic of specific software programs or confirm the calculations entered on substitute tax forms output from software programs. The accuracy of software programs is the responsibility of the software developer, distributor, or user.
