I know there are some school fundraiser hunts around. If you allow your hunting land to be used and guide hunters, are there any tax deductions available or do landowners only do this to help the school?

I would think that you could claim the fair market value based on comparable hunt prices as a charitable donation. We do a lot of charitable hunts on our place but unless I outlay some cash I don't claim anything we are losing enough money just owning land with a bunch of worthless trees on it. Hopefully we got a couple accountants that can chime in and give a better answer.

The owner of XYZ local tire company sponsors a school hunt on his family property. He puts his banner up for the hunt, buys a rifle for the raffle, gets public recognition for supporting the local school, gets a generation of customers.
That sir is an advertising expense and accountants should have no problem putting that cost in the correct column for tax benefits.
