Nonprofit organizations must apply for exemption with the Comptroller's office and receive exempt status before making tax-free purchases. See Form 202 (Word 152kb, PDF 142kb).To apply for exemption, complete AP-207 and provide all required documentation as listed in the application. While organizations without 501c3 status can't apply for grants, there are still ways to legally accept donations, fund their business, and serve the community. When filling out your application for exemption, you will need a copy of your IRS determination letter, if you have one. Complete Charity-Donation-Form-9711.
