The issue in this case is petitioners' 2006 U.S. Tax Ct. LEXIS 27">*29 entitlement to an income tax credit under section 34(a)(2) for gasoline excise tax refundable with respect to certain uses under section 6421. ¹ We hold that petitioners are not entitled to the credit.

Background

Petitioners are for-profit Florida corporations with their principal places of business and mailing addresses in Miami, Florida, at the time their petitions were filed. During the 1998 and 1999 taxable years, petitioners provided paratransit services for the physically and mentally disabled within Miami-Dade County, Florida, and portions of southern Broward County, Florida. The services petitioners provided were in fulfillment of their duties under a contract with Cosmis Mobility Services, Inc. (Cosmis). Cosmis is the transportation services broker for Miami-Dade County. Cosmis was under contract with the Metro-Dade Transit2006 U.S. Tax Ct. LEXIS 27">*30 Authority (Transit Authority) to obtain transportation for the physically and mentally disabled to meet the requirements of the Americans With Disabilities Act of 1990 (ADA), Pub. L. 101-336, 104 Stat. 327. Petitioners had no contractual relationship with the Transit Authority.

Petitioners provided paratransit services exclusively through the use of vans and sedans with seating capacities of fewer than 20 adults, including the driver. Petitioners provided no evidence which permits the allocation of their gasoline usage between sedans and vans.

Petitioners' paratransit services were only available to members of the general public who were certified as disabled under the ADA. The vast majority of petitioners' passengers were individuals requiring transportation within Miami-Dade County.

Disabled passengers requiring paratransit services within Miami- Dade County could either make a reservation or set 127 T.C. 96">*98 up a subscription. A reservation entailed a one-time ride between two points. Passengers were required to place the reservation at least 24 hours in advance, as well as designate the pickup and dropoff locations, and request a date and time for travel. A subscription service was available2006 U.S. Tax Ct. LEXIS 27">*31 if the same trip was taken at the same day and time, at least once a week, week after week. For example, an individual who worked at a particular site for set days and times would obtain a subscription to be picked up and dropped off at the worksite, and picked up and dropped off at home, for the days of the week he or she selected, for the weeks he or she selected. Once a subscription was in place, it was no longer necessary for passengers to phone ahead and reserve transportation. Subscription service riders were also initially required to designate the initial pickup and dropoff locations and times. On any given day of travel, petitioners might have been required to provide "on-demand service" to passengers who were not listed in the original manifest but for medical reasons required immediate transportation.

Prior to each day's operation, Cosmis would obtain the necessary pickup information for each prospective passenger. Petitioners' contract with Cosmis required that petitioners maintain a listing of every trip dispatched and delivered. Cosmis would schedule these rides at least the night before the ride and download the information to petitioners before the travel day. The2006 U.S. Tax Ct. LEXIS 27">*32 information was set out in a daily travel manifest containing the specified schedule to be followed and used exclusively for that specific day. A new daily manifest was generated for each new travel day. Typical daily manifests would contain both reservation and subscription passengers. For each travel day, the daily manifest would contain the specific locations and times of the pickups and dropoffs. The information on daily manifests was subject to change from day-to-day based on daily passenger reservations and subscriptions. A daily manifest might or might not have included a stop that had been included on a previous or subsequent daily manifest. The specific routes traveled and schedules followed by petitioners' sedans and vans were derived from passenger subscriptions and daily reservations. The manifests did not contain the specific routes to be followed; the manifests only listed the names of the passengers and the times and locations of passengers' pickups and 127 T.C. 96">*99 dropoffs. The drivers of the paratransit vehicles were not required to follow any particular route in servicing a run.

For the 1998 and 1999 taxable years, petitioner Medical Transportation Management Corp. (MTMC) claimed2006 U.S. Tax Ct. LEXIS 27">*33 income tax credits of $ 58,673 and $ 62,000, respectively, for excise taxes it paid on gasoline. For the same taxable years, petitioner Zuni Transportation, Inc. (Zuni), claimed income tax credits of $ 32,758 and $ 21,852, respectively. On March 25, 2004, respondent timely mailed separate notices of deficiency denying petitioners the entire gasoline credit amount, and provided the following identical explanation:

   It is determined that you do not meet the requirements for the

   fuel credit for gasoline under section 6421(a) of the Internal

   Revenue Code because you did not operate qualified buses on

   scheduled or fixed routes, and the buses were not available to

   the general public.

Petitioners filed separate petitions with this Court seeking a redetermination. In their respective petitions, petitioners asserted that they met all of the requirements set forth in section 6421(b) and therefore were entitled to the income tax credit under section 34(a).

Discussion

I. Background on Section 34 Credit

Section 34 provides a credit against tax for the amount of excise taxes included in the price of gasoline to the ultimate purchaser of gasoline used2006 U.S. Tax Ct. LEXIS 27">*34 on a farm for farming purposes, for other off-highway business use, by local transit systems, and by the operators of intercity, local, or school buses. See secs. 34, 6420, 6421.

Section 34(a) provides in relevant part:

  SEC. 34(a) General Rule. -- There shall be allowed as a credit

   against the tax imposed by this subtitle for the taxable year an

   amount equal to the sum of the amounts payable to the

   taxpayer --

* * * *

     (2) under section 6421 with respect to gasoline used during

     the taxable year (A) otherwise than as a fuel in a highway

     vehicle or (B) in vehicles while engaged in furnishing

     certain public passenger land transportation service * * *

127 T.C. 96">*100 Section 6421(b) provides in relevant part:

  SEC. 6421(b) Intercity, Local, or School Buses. --

     (1) Allowance. -- Except as provided in paragraph (2) and

     subsection (i), if gasoline is used in an automobile bus

     while engaged in --

        (A) furnishing (for compensation) passenger land

        transportation available to the general public2006 U.S. Tax Ct. LEXIS 27">*35 * * *

* * * *

     the Secretary shall pay (without interest) to the ultimate

     purchaser of such gasoline an amount equal to the product

     of the number of gallons of gasoline so used multiplied by

     the rate at which tax was imposed on such gasoline by

     section 4081.

     (2) Limitation in case of nonscheduled intercity or local

     buses. -- Paragraph (1)(A) shall not apply in respect of

     gasoline used in any automobile bus while engaged in

     furnishing transportation which is not scheduled and not

     along regular routes unless the seating capacity of such

     bus is at least 20 adults (not including the driver).

Petitioners argue that they would be entitled to a payment under section 6421(b)(1)(A) and therefore entitled to claim an income tax credit under section 34(a)(2). Respondent contends that petitioners do not meet the requirements for claiming a payment under section 6421(b)(1)(A).

There are three essential elements to a claim for payment under section 6421(b)(1)(A) in situations (like this one) where the seating capacity2006 U.S. Tax Ct. LEXIS 27">*36 of each vehicle is fewer than 20 adults. A taxpayer must establish that the excise tax was paid on gasoline (1) used in an automobile bus, (2) while engaged in furnishing (for compensation) passenger land transportation available to the general public, and (3) which was scheduled along regular routes. See sec. 6421. We shall address these elements separately.

II. "Automobile Bus" Requirement

Petitioners argue that the vans and 4-door sedans used to transport passengers qualify as "buses". Whether a sedan or van may qualify as an automobile bus under section 6421 is an issue of first impression. The term "bus" for purposes of section 6421 is not defined in the Code, the applicable regulations, or the legislative history. The legislative history suggests that Congress intended to limit the scope of section 6421 to buses. Section 6421 was added to the Code by section 208(c) of the Federal-Aid Highway Act of 1956, Pub. L. 84-627, 70 Stat. 394. As enacted, section 6421(b)(1)127 T.C. 96">*101 originally provided for a payment of excise tax "If gasoline is used * * * in vehicles while engaged in furnishing scheduled common carrier public passenger land transportation service along regular routes". The applicable2006 U.S. Tax Ct. LEXIS 27">*37 version of section 6421(b) was amended by section 233(a) of the Energy Tax of 1978, Pub. L. 95-618, 92 Stat. 3190 (1978 amendment). The word "vehicles" was replaced with "automobile buses". The Senate report explains that "Since bus transportation is more energy-efficient than private automobile transportation, the committee believes it desirable to encourage greater use of bus transportation." S. Rept. 95-529, at 54 (1977), 1978-3 C.B. (Vol. 2) 199, 246. Although Congress made clear its intent to limit the application of the statute to buses, it never defined the word "bus". We therefore assume that Congress intended the word "bus" to carry its "'ordinary, contemporary, common meaning.'" Pioneer Inv. Servs. Co. v. Brunswick Associates Ltd. Pship., 507 U.S. 380">507 U.S. 380, 507 U.S. 380">388, 113 S. Ct. 1489">113 S. Ct. 1489, 123 L. Ed. 2d 74">123 L. Ed. 2d 74 (1993)(quoting Perrin v. United States, 444 U.S. 37">444 U.S. 37, 444 U.S. 37">42, 100 S. Ct. 311">100 S. Ct. 311, 62 L. Ed. 2d 199">62 L. Ed. 2d 199 (1979)); see also Crane v. Commissioner, 331 U.S. 1">331 U.S. 1, 331 U.S. 1">6, 67 S. Ct. 1047">67 S. Ct. 1047, 91 L. Ed. 1301">91 L. Ed. 1301, 1947-1 C.B. 97 (1947) ("Words of statutes -- including revenue acts -- should be interpreted where possible in their ordinary, everyday senses"). Therefore, we shall look to the ordinary meaning of the word "bus" to determine whether petitioners' sedans and vans qualify as buses.

2006 U.S. Tax Ct. LEXIS 27">*38 In determining the ordinary meaning of a statutory term, we first look to the ordinary usage or settled meanings of the words used in the statute by Congress. Hamm v. James (In re James), 406 F.3d 1340">406 F.3d 1340, 406 F.3d 1340">1343 (11th Cir. 2005); Hefti v. Commissioner, 97 T.C. 180">97 T.C. 180, 97 T.C. 180">193 (1991), affd. 983 F.2d 868">983 F.2d 868 (8th Cir. 1993). The word "bus" is short for the word "omnibus" and is commonly defined as "a large motor- driven vehicle designed to carry passengers usu. according to a schedule along a fixed route". Webster's Third New International Dictionary (1993); see also Webster's Tenth New Collegiate Dictionary (2002) for a similar definition. We address whether the vehicles petitioners use meet the definition of "fixed" or "regular" routes in detail infra pp. 16-20 in examining whether petitioners meet the third requirement for obtaining the credit. Notwithstanding the question of fixed routes, we do not believe that the 4-passenger sedans petitioners used qualify as large motor vehicles. Petitioners submitted closeup photographs of 127 T.C. 96">*102 the sedans in question, and it is fairly obvious that the vehicles are not large, even for a sedan.

The definition of the word "omnibus" also does2006 U.S. Tax Ct. LEXIS 27">*39 not favor petitioners. The word "omnibus" is defined as "a public vehicle usu. automotive and 4-wheeled and designed to carry a comparatively large number of passengers." Webster's Third New International Dictionary (1993). Although the description of "omnibus" as 4-wheeled plausibly includes a sedan, the sedans petitioners used would not be able to carry a large number of passengers.

Petitioners argue that because Congress used the term "automobile bus" and not just "bus" in the statute, they must have meant something more expansive than a traditional "bus". Petitioners justify this construction with several different arguments, all of which we reject.

   A. The Prefix "Automobile" Does Not Modify the Meaning of

   "Bus"

Petitioners argue that because the word "automobile" precedes the word "bus" in the statute, Congress must have intended a more expansive definition than the ordinary meaning of the word "bus". Petitioners offer no definition of the phrase "automobile bus", but they simply conclude that "the term 'automobile bus' does not seem to have any significance such that any vehicle, including sedans and vans, qualify * * * if the vehicles were used for transportation2006 U.S. Tax Ct. LEXIS 27">*40 which is regularly scheduled.'" This premise clearly violates "'a cardinal principle of statutory construction' that 'a statute ought, upon the whole, to be so construed that, if it can be prevented, no clause, sentence, or word shall be superfluous, void, or insignificant.'" TRW Inc. v. Andrews, 534 U.S. 19">534 U.S. 19, 534 U.S. 19">31, 122 S. Ct. 441">122 S. Ct. 441, 151 L. Ed. 2d 339">151 L. Ed. 2d 339 (2001) (quoting Duncan v. Walker, 533 U.S. 167">533 U.S. 167, 533 U.S. 167">174, 121 S. Ct. 2120">121 S. Ct. 2120, 150 L. Ed. 2d 251">150 L. Ed. 2d 251 (2001)). Further, petitioners' contention that the word "automobile bus" is insignificant also renders the 1978 amendment substituting automobile bus for vehicle superfluous. One of the stated purposes of the 1978 amendment was to "encourage greater use of bus transportation." S. Rept. 95-529, supra at 54, 1978-3 C.B. (Vol. 2) at 246. We cannot ignore the overwhelming evidence of deliberate intent to include the word "bus" in the statute. Therefore, we reject petitioners' argument. After arguing that the term "automobile 127 T.C. 96">*103 bus" has no significance in the statute, petitioners argue in the alternative that we should accept their proffered plain meaning of "automobile bus". Petitioners surmise that Congress meant to use the word "automobile" in its noun form to describe the traits that the word "bus" is2006 U.S. Tax Ct. LEXIS 27">*41 supposed to have. The noun form of "automobile" is commonly defined as a "four-wheeled automotive vehicle". Webster's Third New International Dictionary (1993). Together with the word "bus", petitioners conclude that Congress meant to include all four- wheeled vehicles which travel on regular routes in defining what vehicles qualify for the exemption. Respondent argues that Congress meant the adjective form of "automobile" to describe bus, which is commonly defined as "automotive", meaning "containing within itself the means of propulsion". Id.

We agree with respondent's interpretation. There is no evidence that Congress intended the plain meaning of "automobile" to alter or expand the plain meaning of the word "bus". The legislative history accompanying section 6421 clarifies that Congress meant only buses should qualify for the credit: "the bill provides for the refund or credit of the taxes paid on gasoline and other motor fuels but only to the extent these fuels are used in a bus engaged in furnishing (for compensation) passenger land transportation available to the general public". S. Rept. 95-529, supra at 56, 1978-3 C.B. (Vol. 2) at 248 (emphasis added). Even if we were to2006 U.S. Tax Ct. LEXIS 27">*42 accept petitioners' interpretation of the word "automobile bus", petitioners would not meet their own definition because as discussed infra pp. 1619, the transportation petitioners provided was not on fixed or regularly scheduled routes. ²

   B. The Legislative History to Section 6421 Does Not Support

   Petitioners' Interpretation

Petitioners argue that the following language from the legislative history accompanying the 1978 amendment of section 6421 supports their expansive definition of "automobile bus":

127 T.C. 96">*104 Explanation of provisions

   The bill removes the excise taxes on highway tires, inner tubes,

   and tread rubber, gasoline and other motor fuels, and

   lubricating oil for private intercity, local2006 U.S. Tax Ct. LEXIS 27">*43 and school bus

   operations.

* * * *

   An "intercity or local bus" means any bus which is used

   predominantly in furnishing (for compensation) passenger land

   transportation available to the general public if either (1) the

   transportation is scheduled and along regular routes, or (2) the

   passenger seating capacity of the bus is at least 20 adults (not

   including the driver). Thus, under the first alternative portion

   of this definition, a bus which is used predominantly (that is,

   more than 50 percent) in providing (for compensation) scheduled

   transportation along regular routes (such as is provided by

   local transit systems or an intercity bus operation providing

   regularly scheduled service along regular routes) will qualify

   for the exemption from the taxes on tires, tubes, and tread

   rubber, regardless of the size of the bus involved. For

   nonscheduled (i.e., charter) operations (covered by the second

   alternative portion of the definition), the exemption is

   available only if the bus has a passenger seating capacity of at

   least 20 adults (not including2006 U.S. Tax Ct. LEXIS 27">*44 the driver) and the

   transportation is available to the general public. The purpose

   of the "at least 20 passenger" requirement is to insure that, in

   situations where regularly scheduled service is not being

   furnished, vans and similar vehicles used for vanpooling or taxi

   service are not eligible for the exemption from these taxes (and

   the fuels taxes).

S. Rept. 95-529, supra at 55, 1978-3 C.B. (Vol. 2) at 247. ³

2006 U.S. Tax Ct. LEXIS 27">*45 Petitioners claim that the "predominant use" language in the legislative history allows them to qualify under the first alternative definition so long as the transportation they provide is scheduled along regular routes. We disagree.

Prior to "construing the statute so as to override the plain meaning of the words used therein" this Court requires "unequivocal evidence of legislative purpose". Huntsberry v. Commissioner, 83 T.C. 742">83 T.C. 742, 83 T.C. 742">747-748 (1984). The excerpt petitioners cites, in our opinion, does not constitute "unequivocal evidence" of legislative intent to override the plain meaning of the words used in the statute. In addition, the language petitioners cite still requires that there is a "bus 127 T.C. 96">*105 which is used predominantly". S. Rept. 95-529, supra at 55, 1978-3 C.B. (Vol. 2) at 247 (emphasis added). The legislative history does not define "bus", which leaves us with the ordinary meaning of the word "bus" that we have already stated petitioners do not qualify under.

We conclude that the sedans do not qualify as "buses". Even though the legislative history petitioners cite plausibly includes vans, we do not need to evaluate whether any vans petitioners used qualify2006 U.S. Tax Ct. LEXIS 27">*46 as buses because our finding that sedans are not buses precludes an application of the credit. Petitioners failed to give an accounting of how many gallons of gas to attribute to each type of vehicle for purposes of the gasoline credit. See sec. 6421(b)(1). Therefore, even if we were to hold that vans qualify as buses, petitioners fail to qualify for the gasoline credit because we have no way of discerning how many gallons of gasoline were used by either type of vehicle. ⁴

III. "Regular Route" Requirement

Since petitioners did not use gasoline in an "automobile bus," they are not entitled to an income tax credit under section 34(a)(2). Nevertheless, for the sake of completeness, we shall determine whether petitioners provided transportation that meets the "regular route" requirement. ⁵Under section 6421(b), transportation must be scheduled "along regular routes"2006 U.S. Tax Ct. LEXIS 27">*47 unless the seating capacity of the bus is at least 20 adults. Petitioners concede that all of the vehicles at issue seated under 20 adults. Therefore, the issue is whether petitioners provided transportation scheduled along regular routes. The Senate report issued in conjunction with the Energy Tax Act of 1978 states that in order for service to qualify as scheduled and on regular routes under the statute, the service must provide "scheduled transportation along regular routes (such as is provided by local transit systems or an intercity bus operation providing regularly scheduled service along regular routes)". S. Rept. 95-529, supra at 55, 1978-3 C.B. (Vol. 2) at 247. Petitioners fail to satisfy this requirement.

127 T.C. 96">*106 Unlike typical local transit systems, there were no published timetables available to the general public that the sedans and vans were required to follow. The schedules were prepared the night before the travel day. 2006 U.S. Tax Ct. LEXIS 27">*48 Although petitioners' services were provided on a daily basis, they did not follow a regular schedule, nor were the routes they traveled "regular". A stop that was listed on a previous day's manifest might or might not have appeared on a subsequent manifest. The existence of reservation passengers and the unpredictability of subscription changes, additions, and cancellations guaranteed that the routes would vary significantly from one day to the next. Such variable scheduling by its nature cannot be considered to constitute a "regularly scheduled service along regular routes".

Petitioners again rely on the "predominant use" found in the Senate report to argue that the transportation was serviced along regular routes. Petitioners argue that the implication of that language, which was set forth supra p. 14 suggests that if a bus is used over 50 percent in providing scheduled transportation along regular routes, then it qualifies under section 6421. Based upon the premise that over 50 percent of their services were subscription riders, petitioners argue that they meet the "predominant use" standard.

Petitioners' argument contains several flaws. First, petitioners failed to establish2006 U.S. Tax Ct. LEXIS 27">*49 that their vans and sedans were used more than 50 percent in furnishing subscription services. Petitioners attempted to elicit such information from their witnesses at trial; however, neither the president of Zuni nor the general manager of MTMC could provide that information based on personal knowledge or any other credible source. ⁶ Second, even if we accepted that premise as fact, it does not impact our finding that the routes traveled by petitioners were not regular. Even with respect to manifests that contained only subscription passengers, to the extent that they existed, it was possible that passengers could change from one week to the next as a result of cancellations or new subscriptions. As evidenced at trial through the testimony of the general manager of Cosmis, there was no way 127 T.C. 96">*107 of knowing, short of asking the driver, whether the vehicle followed the same or similar routes as the corresponding run on a subsequent day or week. Petitioners conceded that the information on the daily manifests was subject to change from day-to-day based on daily passenger reservations and subscriptions. An examination of the daily manifests submitted in the record reveals that no two manifests2006 U.S. Tax Ct. LEXIS 27">*50 contained substantially similar patterns of destinations traveled or pickup/dropoff times. ⁷2006 U.S. Tax Ct. LEXIS 27">*51 The manifests had to be modified on a daily basis to accommodate all of the changes in the needs of the passengers using petitioners' services no matter whether they were regular subscribers or one-time reservation passengers. We conclude that the transportation service petitioners provided, by its very nature, requires irregularity in the routes and schedules to function properly. ⁸

Petitioners argue that it would frustrate the purpose of the ADA to disallow petitioners' claimed gasoline tax credit. Petitioners further argue that the term "scheduled and along regular routes" should be read in light of the paratransit regulations enacted under the ADA. We disagree. The ADA is not a taxing statute, and therefore2006 U.S. Tax Ct. LEXIS 27">*52 it has no applicability to whether petitioners qualify for a credit against their income taxes under section 34. The particular paratransit service petitioners provide qualifies under neither the plain language of section 6421 nor the stated legislative intent. We may not rewrite any of these provisions.

In conjunction with their ADA argument, petitioners argue that one of the underlying purposes of section 6421 is to provide relief for local mass transportation systems, and therefore 127 T.C. 96">*108 we must construe the statute to include paratransit providers as beneficiaries in order to be consistent with and further this purpose. See Greyhound Corp. v. United States, 495 F.2d 863">495 F.2d 863, 495 F.2d 863">868 (9th Cir. 1974) ("Special relief is also provided, in the case of gasoline, diesel fuel, and special motor-fuel taxes, for fuel used in the operation of local or mass transportation systems." (quoting H. Rept. 2022, 84th Cong., 2d Sess. (1956), 1956-2 C.B. 1285, 1289)). The legislative history of the statute as amended in 1978, the statute which we are construing in this case, states as the statute's purpose "to encourage greater use of bus transportation." S. Rept. 95- 529, supra at 54, 2006 U.S. Tax Ct. LEXIS 27">*53 1978-3 C.B. (Vol. 2) at 246 (emphasis added). Petitioner cites authority on statutory interpretation that notes that there is a presumption against an implied repeal of legislative purpose. However, we do not consider our holding to conflict with the purpose of the statute as originally enacted. Nor do we find that the 1978 amendment intended to repeal the stated purpose of the 1956 act. Rather, the 1978 amendment simply designated the scope of the local mass transportation systems that Congress wanted to qualify under section 6421. We cannot accommodate petitioners' request to ignore words in the statute and gloss over stated congressional intent to achieve an overly broad interpretation that allows petitioners to qualify for the credit.

Petitioners do not qualify under the section 34 credit for gasoline taxes because the transportation they provided did not meet the requirements enumerated in section 6421. Petitioners' sedans did not qualify as buses, and petitioners did not provide any evidence for us to bifurcate the credit allowed toward their vans that may have possibly qualified. Thus we decline to reach that issue of whether the vans qualify in2006 U.S. Tax Ct. LEXIS 27">*54 light of the failure of proof. Nor were petitioners' transportation services scheduled and along regular routes. The routes petitioners traveled day-to-day were subject to change based on a myriad of factors. None of the constructions of the statutes petitioners offered were persuasive.

127 T.C. 96">*109 To reflect the foregoing,

Decisions will be entered for respondent.
