IRS Publication 463, What Travel Expenses Are Deductible?

Once you have determined that you are traveling away from your tax home, you can determine what travel expenses are deductible.

You can deduct ordinary and necessary expenses you have when you travel away from home on business. The type of expense you can deduct depends on the facts and your circumstances.

Table 1 summarizes travel expenses you may be able to deduct. You may have other deductible travel expenses that are not covered there, depending on the facts and your circumstances.

Records you should keep When you travel away from home on business, you should keep records of all the expenses you have and any advances you receive from your employer. You can use a log, diary, notebook, or any other written record to keep track of your expenses. The types of expenses you need to record, along with supporting documentation, are described in Table 4 (see Chapter 5).

Separating costs. If you have one expense that includes the costs of meals, entertainment, and other services (such as lodging or transportation), you must allocate that expense between the cost of meals and entertainment and the cost of other services. You must have a reasonable basis for making this allocation. For example, you must allocate your expenses if a hotel includes one or more meals in its room charge.

Travel expenses for another individual. If a spouse, dependent, or other individual goes with you (or your employee) on a business trip or to a business convention, you generally cannot deduct his or her travel expenses.

Employee. You can deduct the travel expenses of someone who goes with you if that person:

  1. Is your employee,

  2. Has a bona fide business purpose for the travel, and

  3. Would otherwise be allowed to deduct the travel expenses.

Business associate. If a business associate travels with you and meets the conditions in (2) and (3) above, you can deduct the travel expenses you have for that person. A business associate is someone with whom you could reasonably expect to actively conduct business. A business associate can be a current or prospective (likely to become) customer, client, supplier, employee, agent, partner, or professional advisor.

Bona fide business purpose. A bona fide business purpose exists if you can prove a real business purpose for the individual's presence. Incidental services, such as typing notes or assisting in entertaining customers, are not enough to make the expenses deductible.

Example. Jerry drives to Chicago on business and takes his wife, Linda, with him. Linda is not Jerry's employee. Linda occasionally types notes, performs similar services, and accompanies Jerry to luncheons and dinners. The performance of these services does not establish that her presence on the trip is necessary to the conduct of Jerry's business. Her expenses are not deductible.

Jerry pays $115 a day for a double room. A single room costs $90 a day. He can deduct the total cost of driving his car to and from Chicago, but only $90 a day for his hotel room. If he uses public transportation, he can deduct only his fare.
