With your IRS Determination Letter in hand, make sure you familiarize yourself with
your state’s
requirements for recognizing your nonprofit’s tax-exempt status. This is an area
where requirements
vary state-by-state. Many states issue their own tax-exempt certificate that can be
used for sales
and use tax purposes, but it may require application and periodic renewal.
