re: Alternative Fuel Credit (5-2-12 Update)

I'm not sure what tax filing software you use (assumming you do your own taxes), but I know on H&R Block when filling out the State return there was a section where you are supposed to check all of the credits that apply. The Alternative Fuel Credit was one of the choices. After you check off that credit, it will bring you to another page where you will give the program additional information. Then when you file, it will suggest that you provide supporting documentation for your Alternative Fuel Credit. I did like some of the other posters on this site suggested and attached my bill of sale, Louisiana state registration and your window sticker.
