This summer are you going on a business trip in the U.S. and tacking on some vacation days? Are you a business owner or self-employed? You may be able to deduct some of your expenses. Transportation costs to and from the business activity location may be 100% deductible if the primary reason for the trip is business. Out-of-pocket expenses for business days are generally fully deductible. Examples include lodging, meals (subject to the 50% disallowance rule), seminar and convention fees, and cab fare. Additional rules and limits apply. Contact us with questions.
