Hi,
Our PTO has just voted to proceed with applying for 501(c)(3). We have good info on the application process, but we would also like to know what it will entail for our group to stay nonprofit once approved. What are we signing up for, for ourselves and for future officers of our PTO?

If your group has been 501(c)(3) for awhile, we'd appreciate your input.

The treasurer in particular would like to know how much additional paperwork and time investment on her part each year? What kind of financial records needed? Is it just filing the 990-N or 990EZ depending on our income, or is there more? Are there state filing requirements too? We are in WI.
