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.

Not required
If you are an exempt organization under Internal Revenue Code (IRC) Sections 501(c) through (f), 501(j), 501(n), 521, or 529, you are exempt from Oregon Corporation taxes (ORS 317.080). You don't have to apply to the Oregon Department of Revenue. Two exceptions to this are nonprofit homes for the elderly and people's utility districts.
