Defining Travel Expenses

Generally, deductible travel expenses are the ordinary and necessary expenses that you incur while you're away from home in pursuit of your trade or business. In order to claim travel expenses as deductions, you must keep adequate records and be able to prove the existence, amount, and business purpose of your expenses.

The following is a list of expenses you may be able to deduct depending on the facts and circumstances:

• 50 percent of the cost of meals when traveling (see discussion below)
• air, rail, and bus fares
• baggage charges
• cleaning and laundry expenses
• computer rental fees
• expenses of operating and maintaining a car, including the cost of gas, oil, lubrication, washing, repairs, parts, tires, supplies, parking fees, and tolls
• expenses of operating and maintaining RVs or house trailers - if such an expense is ordinary and necessary for your business
• hotel expenses
• local transportation costs for taxi fares or other transportation between the airport or station and a hotel, from one customer to another, or from one place of business to another, and tips incidental to the foregoing expenses
• public stenographer or clerical fees
• telephone or fax expenses
• tips on eligible expenses
• transportation costs for sample and display materials and sample room costs

Meal costs when traveling. The cost of dining alone is a deductible expense only if your business trip is overnight or long enough to require that you stop for sleep or rest. Of course, if you entertain business guests at home or away you may be able to deduct the cost, if you meet the usual deductibility rules for meals and entertainment.

In any case, you can deduct only 50 percent of the cost of the meals.

Air transportation employees, interstate truck and bus drivers, railroad employees, and merchant mariners can deduct 80 percent of meal expenses.

Standard meal allowance. Assuming that you are traveling away from home for the required length of time, you may elect to deduct one-half of a Standard Meal Allowance (SMA), rather than half of the actual cost of your meals, laundry, cleaning and tips.

The standard meal allowance refers to the "federal rate for meals and incidental expenses" and the amount varies depending on where and when you travel. Your best source for these rates is the GSA website. You can also find them in IRS Publication 1542, Per Diem Rates (for Travel Within the Continental United States). Note that there is also a per diem rate that includes lodging as well as meals and incidentals, but this combined per diem is generally not available to self-employed people.

Save Time Although there are "standard rates" that apply to many locations, much higher rates apply in many areas. For example, the standard meal allowance for most locations in Illinois is $46/day for for most of 2013 and 2014, but in Chicago, the amount is $71. This means that if you are in Chicago for business, you can deduct $12.50 more per day for meals than the "standard" rate. (Remember, you can deduct only 50% of the allowable amount: $35.50 for Chicago versus $23 for the standard rate.)

Incidental Expenses Only. Even if you do not have meal costs for a given day, you still can deduct your bona fide incidental travel expenses. You can do this using the actual expense method or using a standard rate of $5 a day. You cannot use this method on any day that you use the standard meal allowance.

The term "incidental expenses" includes fees and tips given to porters, baggage carriers, hotel staff, and staff on ships.

For travel in areas outside the continental U.S., you must use federal per diem rates that are published monthly by the government. The foreign per diem rates can be purchased from the Government Printing Office and are also available on the Internet from the State Department.

Tip The advantage to using the standard meal allowance is that you don't have to keep records of actual meal expenses, although you still have to keep records to prove the time, place, and business purpose of your travel. A disadvantage is that the standard meal allowances are not very generous. Chances are that your actual expenses, and therefore your deductions, would be larger.

Spouses and dependents. You may be wondering whether you can deduct the cost of bringing your spouse along on a business trip. The answer is generally no. For the travel expenses of a spouse (or dependent or any other individual for that matter) to be deductible, the spouse (or other individual) must also be an employee of the business. In addition, the spouse's travel must be for a bona fide business purpose and the expenses must be otherwise deductible by the spouse.
