Can I write off business travel expenses?

Business travel expenses are deductible when they are incurred while traveling away from your tax home for business purposes. Deductible expenses include transportation, lodging, meals (subject to a 50% limit), and other necessary costs. However, the travel must be primarily for business, and personal expenses incurred during the trip are not deductible. For example, if you attend a conference related to your business, the costs of travel, lodging, and meals during the conference are deductible, but any personal sightseeing trips are not.
