S.B.
Are you trying to start a non-profit that has a tax exempt status (so you don't have to pay income taxes on money raised or donated??) First you need to read the IRS guidelines to see what you would qualify under and apply for a tax exempt number. You would also have to file papers with the state (may differ depending on the state you are in-probably articles of incorporation. Many people secure the services of an attorney/CPA to start the process for them. good luck.
