I have included a few links that should be helpful. I also recommend that you have a short meeting with an attorney that provides NFP advice.
You may or may not have to file for NFP status according to the form 1023-EZ instructions:
https://www.irs.gov/pub/irs-pdf/i1023ez.pdf
If you don't file for NFP status, you will be a taxable entity, which will depend on how you completed your SS-4.
Get some upfront legal and tax advice. Even though the $$ are not significant, penalties for not filing correctly will easily exceed any tax liability, if applicable.

Since this is most likely a very small group, any filing requirements should not be overly taxing, but you need to understand which forms are applicable.
*A reminder that posts in a forum such as this do not constitute tax advice.
Also keep in mind the date of replies, as tax law changes.
