Advertising expenses. You generally can deduct reasonable advertising expenses that are directly related to your business activities.
You can usually deduct as a business expense the cost of institutional or goodwill advertising to keep your name before the public if it relates to business you reasonably expect to gain in the future. For example, the cost of advertising that encourages people to contribute to the Red Cross, to buy U.S. Savings Bonds, or to participate in similar causes is usually deductible.
