THree steps. THe first is to incorporate in Oregon. You must submit an Article of Corporation with the names of the Board Members. About $75.00. There are books in the public library to do this. You are incorporating as a non-stock corporation.
You MUST include the 501C3 language from the Federal publication in the articles if incorportation. I had to re-submit (only $25.00).

Sent IRS S4 form to get employeer number (IRS tracks non profits by this number-we have no employees either)

THe federal publication will help with the last step. Bi-laws, articles of incorporation, handouts, etc go to the IRS. $150.00
