You must include in gross income in the year of receipt the fair market value of goods or services received from bartering. Generally, you report this income on Form 1040, Schedule C.pdf, Profit or Loss from Business (Sole Proprietorship), or Form 1040, Schedule C-EZ.pdf, Net Profit from Business (Sole Proprietorship). If you failed to report this income, correct your return by filing a Form 1040X.pdf, Amended U.S. Individual Income Tax Return. Refer to Topic No. 308 and Should I File an Amended Return? for information on filing an amended return.
At least at for my children, all of the little league sports are sponsored by different local businesses. They usually pay the cost of uniforms and donate a certain amount of snacks and such. In return, they get their company name on the jersey. The school often have fundraiser auctions and things, too, that are sponsored by the booster club. A lot of places donate laptops or other items in exchange for them mentioning that their company donated the product.
