I started a nonprofit organization that's recognized as a 501(c)3 by the IRS. I'm the President/CEO, can I deduct filing fees/material expenses incurred for start-up?

If so, how do I claim/deduct that on my personal taxes? Would it be considered a donation or contribution to get the nonprofit started or would it be an unreimbursed company expense? I just want to make sure I'm not doing anything that would negatively impact me or the nonprofit.
