Final answer:
Fred must include the $500 gift for services, the $1000 value of the van, and the $600 in gasoline received for tutoring on his tax return; the $300 of interest income typically would be reported by his uncle unless transferred to Fred.
Step-by-step explanation:
According to tax regulations, sources of income can have varying treatments. In Fred's situation, the $500 gift he received for helping a friend is considered income and must be included in his income tax return since it was for services rendered. The $300 of interest assigned to him that was due to his uncle from bonds would typically be reported by his uncle, not Fred, unless there was some agreement to transfer the interest to Fred. The use of the van is a non-cash fringe benefit; if it was provided for personal use, then the fair market value of $1000 should also be included in his gross income. Finally, the $600 in gasoline received from the station owner in exchange for tutoring services constitutes barter income which is taxable and therefore must also be reported on Fred's tax return.
