This is one of CPA's most common answers to questions they're asked–it really depends. The IRS requires that business expenses be ordinary and necessary to be deductible. For example, a real estate agent could make a strong case for deducting vinyl wrapping their car to advertise their services. However, it would be much harder to make the same argument for a self-employment software engineer that works out of their home. In addition, if you're considering having non-traditional advertisement expenses, such as TV, radio billboard, etc., please schedule a consultation with one of our tax managers to discuss your unique situation.
