We started a small parts selling business to help offset the cost of our racing. I am looking for a good book or guide to help with Indiana tax.
I have a pretty good understanding of sales tax for the parts we sell, however Id like a better understanding of what we can deduct on our own cars for advertisment, and promotional purposes.

If anyone knows of a good publication that is focused on our sport I would be appreciative,
