Do travel credits converted to cash in a personal travel account established by an employer constitute gross income to the employee for federal income tax purposes?

I

Dr. Philip Charley and his wife Katherine Charley appeal the tax court’s determination of an income tax deficiency for tax year 1988 in the amount of $882 and an addition to tax of $44 pursuant to Internal Revenue Code (“IRC”) § 6653. We affirm on the merits and reverse the penalty.

During 1988, Truesdail Laboratories (“Truesdail”) engaged in the testing business, including testing urine for horse racing activities and investigating the causes of industrial accidents. Philip was the President of Truesdail and, together with Katherine, owned 50.255% of its shares. Philip performed various services for Truesdail including inspecting mechanical devices suspected of failure.

Philip, in his capacity as an employee of Truesdail, traveled to various accident sites to inspect machinery. Truesdail had an “unwritten policy” that the frequent flyer miles that were earned during an employee’s travel for Truesdail became the sole property of the employee.

During the year at issue, the following procedures were followed by Truesdail with respect to Philip’s travel:

Over the course of 1988, Archer maintained separate travel accounts for Philip and Truesdail. Philip took four business trips that year, and using the procedures outlined above, received $3,149.93 in his personal travel account from his “sale” of the frequent flyer miles.

The parties stipulated that Philip and Katherine did not know that the receipt of the travel credits was taxable income, and that they did not intend to conceal the process utilized to obtain the travel credits.

The tax court held that the travel credits constituted taxable income. The tax court also upheld imposition of an addition to tax by the Internal Revenue Service (“IRS”) of $44 pursuant to former IRC § 6653(a)(1), which provided for an addition to tax if any part of an underpayment resulted from negligence or intentional disregard of rules and regulations.

The petitioners appeal both the tax court’s determination of an income tax deficiency and its imposition of the addition to tax (penalty).

The statute at issue, IRC § 61, provides that gross income “means all income from whatever source derived.” Gross income has been defined as an “undeniable accession[ ] to wealth, clearly realized, and over which the taxpayer[ ][has] complete dominion.” Commissioner v. Glenshaw Glass, 348 U.S. 426, 431 , 75 S.Ct. 473, 477 , 99 L.Ed. 488 (1955). The tax court noted that there was no indication Philip could not use the travel credits for personal travel or redeem them for cash. Consequently, the tax court upheld the IRS’ determination of deficiency on the ground that:

The Charleys do not dispute the tax court’s finding that travel credits were Philip’s to use for personal travel. Nor do they dispute the tax court’s conclusion that Philip had sole control over the credits in his account. Rather, the Charleys argue that no taxable event occurred. We find this argument unpersuasive.

The Charleys argue that this case raises the question of whether, in the abstract, frequent flyer miles constitute gross income. We disagree and do not reach that issue.

As the tax court noted, the case can be analyzed in one of two ways. First, the travel credits which were converted to cash can be characterized as additional compensation. On this view, Philip received property from his employer in the form of an account upon which he could draw up to $3,149.93, which he did. This is so because Truesdail paid for first-class airfare and allowed Archer to credit Philip’s account with the difference between the first-class price and the coach price. The funds constituting the difference came from Truesdail;' Philip consequently received compensation in the amount of $3,149.93 from his employer. The fact that the travel credits were exchanged for frequent flyer miles simply is not relevant to the analysis.

In the alternative, if it is assumed that the frequent flyer miles were not given to Philip by Truesdail, but belonged to him all along, then the transaction can be viewed as a disposition of his own property. Gross income includes “[g]ains derived from dealings in property.” IRC § 61(a)(3). A gain from the disposition of property is equal to the “amount realized” from the disposition minus the property’s adjusted basis. IRC § 1001(a). The amount realized from a disposition of property is the sum of any money received plus the fair market value of the property (other than money) received. IRC § 1001(b). The adjusted basis is generally determined by reference to cost. IRC § 1012.

Because Philip received the frequent flyer miles at no cost, he had a basis of zero. He then exchanged his frequent flyer miles for cash, resulting in a gain of $3,149.93 (the fair market value of the property received minus the adjusted basis of zero).

Thus, the funds credited to Philip’s account are taxable, whether they are characterized as a gain from the disposition of property or as additional compensation, unless he can show that they qualify for an exclusion. Philip cannot maintain that the funds constituted a non-taxable gift because IRC § 102(c), concerning exclusions for gifts, provides that “[sjubseetion (a) shall not exclude from gross income any amount transferred by or for an employer to, or for the benefit of, an employee.”

Philip argues the credits should be construed as a “no-additional-cost service,” which is excludable pursuant to IRC § 132(a). However, in order to qualify for this exclusion, the service in question must, among other things, be “offered for sale to customers in the ordinary course of the line of business of the employer in which the employee is performing services.” IRC § 132(b). Truesdail obviously did not offer frequent flyer miles to customers in the ordinary course of its business; thus, the travel credits at issue here cannot be deemed an excludable no-additional-cost service.

In sum, we hold that the tax court was correct in concluding that the travel credits under the facts of this case constituted taxable income.

III

The IRS imposed an addition to tax in the amount of $44 pursuant to the former version of IRC § 6653, which provided for an addition to tax if any part of an underpayment is due to negligence or intentional disregard of rules or regulations.

Philip has the burden of proving that the underpayment was not due to negligence. Allen v. Commissioner, 925 F.2d 348, 353 (9th Cir.1991). Former section 6653(a)(3) defined “negligence” as including “any failure to make a reasonable attempt to comply with the provisions of this title.” Similarly, case-law has defined “negligence” as the “lack of due care or the failure to do what a reasonable and prudent person would do under similar circumstances.” Allen, 925 F.2d at 353 .

We are persuaded that the tax court erred in sustaining the penalty. There is nothing in the record which would cause a reasonable person to conclude that the travel credit conversion would constitute taxable income. As the government conceded in its brief, “the tax treatment of frequent flyer bonus programs is still under consideration.” There is no showing that the conventional personal use of frequent flyer miles in the late 1980s gave rise to taxable income under then-current IRS policy. Therefore, the penalty for negligent or intentional disregard of IRS rules was not warranted.

The decision of the tax court is AFFIRMED in part and REVERSED in part. Each party shall bear his or her own costs on appeal.

. In 1989, § 7721 of Pub.L. 101-239 amended 26 IRC § 6653 generally, substituting provisions relating to failure to pay stamp tax for provisions relating to additions to tax for negligence and fraud. The provisions relating to negligence and fraud are now codified at 26 IRC § 6662(c).
