Although video conferencing has made inroads in the ranks of business travelers, there still are many situations where it’s necessary to travel away-from-home overnight for face-to-face meetings with staff, management, or customers. Businesspeople or professional who must travel for work reasons should keep in mind that they may be able to qualify for a travel bargain by piggybacking a vacation onto an out-of-town business trip. In effect, the business traveler gets free vacation airfare if the trip is set up the right way. And if the travel is undertaken for an employer, a properly set up reimbursement arrangement for the business portion of the trip will be income- and payroll-tax-free. This Tax Tip takes a closer look at how this combination works for domestic travel, along with a review of other business travel strategies that may yield personal savings. It doesn’t cover some of the more specialized rules, such as those that apply to travelers in the transportation industry, or the per diem reimbursement rules.

Deductions for trip undertaken primarily for business. A taxpayer who mixes a bit of pleasure with business while away from home nonetheless may deduct all of the round-trip transportation costs as long as the trip was undertaken primarily for business reasons. The cost of lodging plus 50% of meals while on business status is deductible. Additionally, if the traveler is an employee reimbursed for all expenses under an accountable plan that requires a timely accounting of the time, place, and business purpose of the travel, plus receipts, the reimbursement is tax-free to the traveler (but the personal portion of the trip yields no tax benefit to the traveler).

In effect, the 100% deduction for the round-trip travel costs works as a kind of tax subsidy for a personal vacation, or as a partially tax-free perk.

  • Illustration 1: Jane, a self-employed information technology specialist, flies from the East Coast to Los Angeles for a 5-day business trip. She takes in three days of vacation and sight-seeing after the business part of the trip is over.
    Result: Because Jane can deduct the entire air fare, part of her mini-vacation is, in effect, subsidized by the tax break.
  • Illustration 2: The facts are the same as in illustration (1), except that Jane is employed by a corporation that reimburses her for the business portion of the trip after she submits detailed records and receipts. She pays for the personal portion of the trip (meals and lodging during the three personal days).
    Result: Under the accountable plan rules, the reimbursement for the round-trip airfare (as well as for meals and lodging while on business status) is tax-free to Jane, and is not subject to FICA or income tax withholding. That’s true even though she took a mini-vacation after her business trip ended. The corporation deducts the travel costs it pays (but only 50% of the cost of meals is deductible).
  • Illustration 3: The facts are the same as in illustration (2), except that the corporation reimburses Jane for the cost of the entire trip, including the 3-day mini-vacation.Result: Her cost for the personal portion of the trip consists of the tax she pays on the personal portion’s value (hotel, meals, etc.), which must be treated as compensation income. The corporation’s deduction consists of 50% of the meal costs while Jane is on business travel status, 100% of the round-trip air fare, 100% of the lodging costs while she is on travel status, and (assuming that her entire compensation package is “reasonable”) 100% of the cost of the mini-vacation since that was treated as compensation paid to Jane.

When is a trip treated as undertaken primarily for business? There is no hard-and-fast rule. It depends on the facts and circumstances of each case. The regs do say, however, that the way travelers split their time between business and personal pursuits is “an important factor.”

  • Illustration 4: Fred works in Atlanta and travels to New Orleans on business. On his way home, he stops in Mobile to visit his parents. During the nine days he is away from home, he spends $1,999 for travel, meals, lodging, and other travel expenses. Had he not stopped in Mobile, Fred would have been away from home for only six days and his trip would have cost only $1,699.Result: Fred can deduct $1,699 for his trip, including the round-trip transportation to and from New Orleans. The 50% deduction limit applies to his meals while on business status. (IRS Pub. 463 (2010), p. 6)

Observation: As is evident from illustration (4), the personal part of a trip need not occur at the business destination. It can take place on the way home from the business destination (or, for that matter, en route to the business destination).

Caution: Taxpayers who make a stop for personal reasons en route to a business location or on the way home should be sure to keep records of what their round-trip transportation costs would have been without the personal stop.


Saturday night stayovers.

Although an employee’s out-of-town business chores conclude on Friday, he may extend his business trip to take advantage of a low-priced fare requiring a Saturday night stayover, where the savings in airfare are higher than the costs of the weekend meals and lodging. The employee doesn’t pay tax on the reimbursement for his Saturday meal and lodging expenses. In this case, IRS said that under a “common sense test,” payments to the employee for the Saturday stay were deductible if a “hardheaded business person would have incurred such expenses under like circumstances.”

When a personal day may not be a personal day.

An away-from-home business trip may straddle a weekend. For example, a traveler may have to attend business meetings on Thursday, Friday, and Monday. He is too far away to travel home and then come back (and besides, the trip back and forth would cost more than staying put), so he spends the weekend relaxing at the out-of-town location. Because he must remain at the location for business reasons, the weekend days (Saturday and Sunday) should under the “common sense test” be treated as business days the expenses for which are deductible (50% of meal costs, 100% for other expenses) or excludible if the traveler is reimbursed under an accountable plan.

Tax break for weekend travel home.

A business traveler on an extended out-of-town assignment may decide to fly home for a weekend to be with family or friends. The cost of the weekend trip home is deductible up to the amount the traveler would have spent on meals and lodging at the out-of-town location. Note, however, that this rule applies only if the traveler checks out of the out-of-town hotel before leaving for the weekend trip home, and then re-registers. If the traveler retains the hotel room, its cost is deductible, but the deduction for the weekend trip home (i.e., the air fare) is limited to what the traveler would have spent on meals during the weekend at the out-of-town location.

Tax breaks when spouse or companion comes along.

The expenses of a spouse or other companion accompanying a traveler aren’t deductible unless (1) the spouse or other companion is an employee of the taxpayer and travels for a bona fide business purpose, and (2) the expenses would otherwise be deductible by the spouse or other companion. (Code Sec. 274(m)(3)) Nevertheless, even if the spouse’s or other companion’s travel expenses aren’t deductible, a tax benefit may still be salvaged from traveling together. That’s because the business traveler’s deduction isn’t based on 50% of the trip expenses. The deduction is based on what it would have cost the taxpayer to travel alone. (Rev Rul 56-168, 1956-1 CB 93) This rule can be a money saver on accommodations. For example, where the cost of a hotel room is $200 for one occupant and $149 for two, a taxpayer on business status may deduct $149 per night, not $100, when he gets a room for two.

Similarly, where the taxpayer travels out of town on business via rental car, and his spouse or other companion accompanies him for non-business purposes, the entire cost of the rental is deductible, because the cost would have been the same for the taxpayer even if his spouse did not join him on the trip.
