raesmom,
If you already have 501(c)(3) status, any changes you make to your governing documents (bylaws, charters, etc.,), point of contact agent, major fundraising or budget items must be submitted to the IRS. The specific requirement is in the 557 Publication.
As I read this these are new by laws for a new organization.
Are you applying for 501(c)(3) status? If so the basic answer to your question is yes but not everyone needs sign them. You need the signature of at least 2 people.
We updated our by laws. The changes made were read before the general members and adopted. Then they were submitted to the IRS. I think it was "Ask Elly", but somewhere in PTO Today I read that changes have to be submitted to the IRS.
If you had a committee working on the bylaws I would have them sign it. If not probably just whoever was at the meeting that voted on the approved bylaws. I don't think you need to file them with the IRS. In MA we don't have to file them with the IRS just the Attorney Generals Office - Division of Public Charities. Check it out for your state though. Someone else here might have more info. for you.
I have posted our bylaws in the school office for a week and will have a meetings to adopt the bylaws on Tuesday. Do I need to get the members to sign the bylaws if we agree to pass what has been posted?
Do I then call IRS to get everything else in order?
