How do we apply for an exemption? After completing the online application, select Receive Letter Online and click on the Submit Application button.If your church or ministry needs a Tax ID, the link to apply online is below. You can also print out and mail a form (Form SS-4). See Form 202 (Word 152kb, PDF 142kb). Nonprofit organizations must apply for exemption with the Comptroller's office and receive exempt status before making tax-free purchases. The information provided on this form will help the Internal Revenue Service (IRS) determine if there has been a violation of federal tax. You'll include the church's name, address, and tax ID number. DFW Church of Christ is a 501(c)(3) non-profit organization. When filling out your application for exemption, you will need a copy of your IRS determination letter, if you have one.
