Ummmm...yeah there is. Farmers can claim a credit for all the taxes paid on gasoline and aviation fuel on their taxes.
“You can claim a credit or refund of taxes on fuel used on a farm for farming purposes. This applies if you are the owner, tenant, or operator of a farm. You can claim only a credit for the tax on gasoline used on a farm for farming purposes. You can claim either a credit or refund for the tax on aviation fuel used on a farm for farming purposes.”
At the end of the year, yes. But when you buy it, the only tax you DONT pay is the road tax. You still pay the sales tax. I'd be more than happy to grab the fuel and tax records if you'd like... I do have first had experience with this subject.
