If you temporarily travel away from your tax home, you can use this section to determine if you have deductible travel expenses. This section discusses:
-
Traveling away from home,
-
Tax home,
-
Temporary assignment or job, and
-
What travel expenses are deductible.
It also discusses the standard meal allowance, rules for travel inside and outside the United States, and deductible convention expenses.
You are traveling away from home if:
-
Your duties require you to be away from the general area of your tax home (defined later) substantially longer than an ordinary day's work, and
-
You need to sleep or rest to meet the demands of your work while away from home.
This rest requirement is not satisfied by merely napping in your car. You do not have to be away from your tax home for a whole day or from dusk to dawn as long as your relief from duty is long enough to get necessary sleep or rest.
Example 1.
You are a railroad conductor. You leave your home terminal on a regularly scheduled round-trip run between two cities and return home 16 hours later. During the run, you have 6 hours off at your turnaround point where you eat two meals and rent a hotel room to get necessary sleep before starting the return trip. You are considered to be away from home.
Example 2.
You are a truck driver. You leave your terminal and return to it later the same day. You get an hour off at your turnaround point to eat. Because you are not off to get necessary sleep and the brief time off is not an adequate rest period, you are not traveling away from home.
To determine whether you are traveling away from home, you must first determine the location of your tax home.
Generally, your tax home is your regular place of business or post of duty, regardless of where you maintain your family home. It includes the entire city or general area in which your business or work is located.
If you have more than one regular place of business, your tax home is your main place of business. See Main place of business or work, later.
If you do not have a regular or a main place of business because of the nature of your work, then your tax home may be the place where you regularly live. See No main place of business or work, later.
If you do not have a regular place of business or post of duty and there is no place where you regularly live, you are considered an itinerant (a transient) and your tax home is wherever you work. As an itinerant, you cannot claim a travel expense deduction because you are never considered to be traveling away from home.
-
The total time you ordinarily spend in each place.
-
The level of your business activity in each place.
-
Whether your income from each place is significant or insignificant.
-
You perform part of your business in the area of your main home and use that home for lodging while doing business in the area.
-
You have living expenses at your main home that you duplicate because your business requires you to be away from that home.
-
You have not abandoned the area in which both your historical place of lodging and your claimed main home are located; you have a member or members of your family living at your main home; or you often use that home for lodging.
Example.
You are single and live in Boston in an apartment you rent. You have worked for your employer in Boston for a number of years. Your employer enrolls you in a 12-month executive training program. You do not expect to return to work in Boston after you complete your training.
During your training, you do not do any work in Boston. Instead, you receive classroom and on-the-job training throughout the United States. You keep your apartment in Boston and return to it frequently. You use your apartment to conduct your personal business. You also keep up your community contacts in Boston. When you complete your training, you are transferred to Los Angeles.
You do not satisfy factor (1) because you did not work in Boston. You satisfy factor (2) because you had duplicate living expenses. You also satisfy factor (3) because you did not abandon your apartment in Boston as your main home, you kept your community contacts, and you frequently returned to live in your apartment. You have a tax home in Boston.
Example 1.
You are a truck driver and you and your family live in Tucson. You are employed by a trucking firm that has its terminal in Phoenix. At the end of your long runs, you return to your home terminal in Phoenix and spend one night there before returning home. You cannot deduct any expenses you have for meals and lodging in Phoenix or the cost of traveling from Phoenix to Tucson. This is because Phoenix is your tax home.
Example 2.
Your family home is in Pittsburgh, where you work 12 weeks a year. The rest of the year you work for the same employer in Baltimore. In Baltimore, you eat in restaurants and sleep in a rooming house. Your salary is the same whether you are in Pittsburgh or Baltimore.
Because you spend most of your working time and earn most of your salary in Baltimore, that city is your tax home. You cannot deduct any expenses you have for meals and lodging there. However, when you return to work in Pittsburgh, you are away from your tax home even though you stay at your family home. You can deduct the cost of your round trip between Baltimore and Pittsburgh. You can also deduct your part of your family's living expenses for meals and lodging while you are living and working in Pittsburgh.
You may regularly work at your tax home and also work at another location. It may not be practical to return to your tax home from this other location at the end of each work day.
-
For the federal government,
-
In a temporary duty status, and
-
To investigate or prosecute, or provide support services for the investigation or prosecution of a federal crime.
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 26-1 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.

-
Is your employee,
-
Has a bona fide business purpose for the travel, and
-
Would otherwise be allowed to deduct the travel expenses.
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 $199 a day for a double room. A single room costs $149 a day. He can deduct the total cost of driving his car to and from Chicago, but only $149 a day for his hotel room. If he uses public transportation, he can deduct only his fare.
| IF you have expenses for... | THEN you can deduct the cost of... |
| transportation | travel by airplane, train, bus, or car between your home and your business destination. If you were provided with a ticket or you are riding free as a result of a frequent traveler or similar program, your cost is zero. If you travel by ship, see Luxury Water Travel and Cruise ships (under Conventions) in Publication 463 for additional rules and limits. |
| taxi, commuter bus, and airport limousine | fares for these and other types of transportation that take you between:
|
| baggage and shipping | sending baggage and sample or display material between your regular and temporary work locations. |
| car | operating and maintaining your car when traveling away from home on business. You can deduct actual expenses or the standard mileage rate as well as business-related tolls and parking. If you rent a car while away from home on business, you can deduct only the business-use portion of the expenses. |
| lodging and meals | your lodging and meals if your business trip is overnight or long enough that you need to stop for sleep or rest to properly perform your duties. Meals include amounts spent for food, beverages, taxes, and related tips. See Meals and Incidental Expenses for additional rules and limits. |
| cleaning | dry cleaning and laundry. |
| telephone | business calls while on your business trip. This includes business communication by fax machine or other communication devices. |
| tips | tips you pay for any expenses in this chart. |
| other | other similar ordinary and necessary expenses related to your business travel. These expenses might include transportation to or from a business meal, public stenographer's fees, computer rental fees, and operating and maintaining a house trailer. |
You can deduct the cost of meals in either of the following situations.
-
It is necessary for you to stop for substantial sleep or rest to properly perform your duties while traveling away from home on business.
-
The meal is business-related entertainment.
Business-related entertainment is discussed under Entertainment Expenses, later. The following discussion deals only with meals (and incidental expenses) that are not business-related entertainment.
-
Fees and tips given to porters, baggage carriers, bellhops, hotel maids, stewards or stewardesses and others on ships, and hotel servants in foreign countries,
-
Transportation between places of lodging or business and places where meals are taken, if suitable meals can be obtained at the temporary duty site, and
-
Mailing costs associated with filing travel vouchers and payment of employer-sponsored charge card billings.

-
Directly involves moving people or goods by airplane, barge, bus, ship, train, or truck, and
-
Regularly requires you to travel away from home and, during any single trip, usually involves travel to areas eligible for different standard meal allowance rates.
-
Method 1: You can claim of the standard meal allowance.
-
Method 2: You can prorate using any method that you consistently apply and that is in accordance with reasonable business practice.
Example.
Jen is employed in New Orleans as a convention planner. In March, her employer sent her on a 3-day trip to Washington, DC, to attend a planning seminar. She left her home in New Orleans at 10 a.m. on Wednesday and arrived in Washington, DC, at 5:30 p.m. After spending two nights there, she flew back to New Orleans on Friday and arrived back home at 8:00 p.m. Jen's employer gave her a flat amount to cover her expenses and included it with her wages.
Under Method 1, Jen can claim 2½ days of the standard meal allowance for Washington, DC: of the daily rate for Wednesday and Friday (the days she departed and returned), and the full daily rate for Thursday.
Under Method 2, Jen could also use any method that she applies consistently and that is in accordance with reasonable business practice. For example, she could claim 3 days of the standard meal allowance even though a federal employee would have to use method 1 and be limited to only 2½ days.
The following discussion applies to travel in the United States. For this purpose, the United States includes the 50 states and the District of Columbia. The treatment of your travel expenses depends on how much of your trip was business related and on how much of your trip occurred within the United States. See Part of Trip Outside the United States, later.
You can deduct all your travel expenses if your trip was entirely business related. If your trip was primarily for business and, while at your business destination, you extended your stay for a vacation, made a personal side trip, or had other personal activities, you can deduct your business-related travel expenses. These expenses include the travel costs of getting to and from your business destination and any business-related expenses at your business destination.
Example.
You work in Atlanta and take a business trip to New Orleans. On your way home, you stop in Mobile to visit your parents. You spend $1,070 for the 9 days you are away from home for travel, meals, lodging, and other travel expenses. If you had not stopped in Mobile, you would have been gone only 6 days, and your total cost would have been $920. You can deduct $920 for your trip, including the cost of round-trip transportation to and from New Orleans. The deduction for your meals is subject to the 50% limit on meals mentioned earlier.
If your trip was primarily for personal reasons, such as a vacation, the entire cost of the trip is a nondeductible personal expense. However, you can deduct any expenses you have while at your destination that are directly related to your business.
A trip to a resort or on a cruise ship may be a vacation even if the promoter advertises that it is primarily for business. The scheduling of incidental business activities during a trip, such as viewing videotapes or attending lectures dealing with general subjects, will not change what is really a vacation into a business trip.
If part of your trip is outside the United States, use the rules described later under Travel Outside the United States for that part of the trip. For the part of your trip that is inside the United States, use the rules for travel in the United States. Travel outside the United States does not include travel from one point in the United States to another point in the United States. The following discussion can help you determine whether your trip was entirely within the United States.
Example.
You fly from New York to Puerto Rico with a scheduled stop in Miami. You return to New York nonstop. The flight from New York to Miami is in the United States, so only the flight from Miami to Puerto Rico is outside the United States. Because there are no scheduled stops between Puerto Rico and New York, all of the return trip is outside the United States.
Example.
You travel by car from Denver to Mexico City and return. Your travel from Denver to the border and from the border back to Denver is travel in the United States, and the rules in this section apply. The rules under Travel Outside the United States apply to your trip from the border to Mexico City and back to the border.
If any part of your business travel is outside the United States, some of your deductions for the cost of getting to and from your destination may be limited. For this purpose, the United States includes the 50 states and the District of Columbia.
How much of your travel expenses you can deduct depends in part upon how much of your trip outside the United States was business related.
See chapter 1 of Publication 463 for information on luxury water travel.
You can deduct all your travel expenses of getting to and from your business destination if your trip is entirely for business or considered entirely for business.
-
Are an employee who was reimbursed or paid a travel expense allowance,
-
Are not related to your employer, and
-
Are not a managing executive.
-
You were outside the United States for more than a week, and
-
You spent less than 25% of the total time you were outside the United States on nonbusiness activities.
If you travel outside the United States primarily for business but spend some of your time on nonbusiness activities, you generally cannot deduct all of your travel expenses. You can only deduct the business portion of your cost of getting to and from your destination. You must allocate the costs between your business and nonbusiness activities to determine your deductible amount. These travel allocation rules are discussed in chapter 1 of Publication 463.

If you travel outside the United States primarily for vacation or for investment purposes, the entire cost of the trip is a nondeductible personal expense. If you spend some time attending brief professional seminars or a continuing education program, you can deduct your registration fees and other expenses you have that are directly related to your business.
You can deduct your travel expenses when you attend a convention if you can show that your attendance benefits your trade or business. You cannot deduct the travel expenses for your family.
If the convention is for investment, political, social, or other purposes unrelated to your trade or business, you cannot deduct the expenses.

You may be able to deduct business-related entertainment expenses you have for entertaining a client, customer, or employee.
You can deduct entertainment expenses only if they are both ordinary and necessary (defined earlier in the Introduction) and meet one of the following tests.
-
Directly-related test.
-
Associated test.
Both of these tests are explained in chapter 2 of Publication 463.

In general, you can deduct only 50% of your business-related meal and entertainment expenses. (If you are subject to the Department of Transportation's “hours of service” limits, you can deduct a higher percentage. See Individuals subject to “hours of service” limits, later.)
The 50% limit applies to employees or their employers, and to self-employed persons (including independent contractors) or their clients, depending on whether the expenses are reimbursed.
Figure 26-A summarizes the general rules explained in this section.
The 50% limit applies to business meals or entertainment expenses you have while:
-
Traveling away from home (whether eating alone or with others) on business,
-
Entertaining customers at your place of business, a restaurant, or other location, or
-
Attending a business convention or reception, business meeting, or business luncheon at a club.
Generally, business-related meal and entertainment expenses are subject to the 50% limit. Figure 26-A can help you determine if the 50% limit applies to you.
Your meal or entertainment expense is not subject to the 50% limit if the expense meets one of the following exceptions.
-
Certain air transportation workers (such as pilots, crew, dispatchers, mechanics, and control tower operators) who are under Federal Aviation Administration regulations.
-
Interstate truck operators and bus drivers who are under Department of Transportation regulations.
-
Certain railroad employees (such as engineers, conductors, train crews, dispatchers, and control operations personnel) who are under Federal Railroad Administration regulations.
-
Certain merchant mariners who are under Coast Guard regulations.
