The issue in this case is whether certain Alaskan helicopter sightseeing tours

of Temsco Helicopters, Inc. ("Taxpayer"), which were primarily offered to

passengers from cruise ships, were subject to the "Transportation Tax" imposed

under § 4261 of the Internal Revenue Code during tax years 2001 through 2004. 

The sightseeing tours are exempt from the Transportation Tax unless the

transportation was "operated on an established line." I.R.C. § 4281. On cross- 1

motions for summary judgment in which both sides relied on the same facts, the

district court held the flights were not operated on an established line and therefore

not subject to the Transportation Tax. The ruling on summary judgment is

reviewed de novo. Legal Aid Serv. of Or. v. Legal Serv. Corp., 608 F.3d 1084,

1093 (9th Cir. 2010). We hold that the undisputed facts only support that the

flights were operated on an established line and that the flights were subject to the

Transportation Tax. The judgment of the district court will be vacated and this

case remanded for further proceedings to determine the amount of tax due. A

remand is also necessary to determine whether the failure-to-pay penalty under

I.R.C. § 6651(a)(2) is applicable.

A longstanding regulation defines "operated on an established line" as

meaning: "operated with some degree of regularity between definite points. It
-3-

does not necessarily mean that strict regularity of schedule is maintained; that the

full run is always made; that a particular route is followed; or that intermediate

stops are restricted. The term implies that the person rendering the service

maintains and exercises control over the direction, route, time, number of

passengers carried, etc." Treas. Reg. § 49.4263-5(c).

The "operated on an established line" language was taken from prior statutes

imposing the same Transportation Tax on motor vehicle transportation. See H.R.

Rep. No. 85-481, at 48-49 (1957), reprinted in 1958-3 C.B. 372, 419-20. Congress

is presumed to have known of case law, regulations, and rulings construing the

prior statute and to have intended § 4281 to be construed in the same manner. See

United States v. Hayes, 129 S. Ct. 1079, 1086 (2009); Gray Line Co. v. Granquist,

237 F.2d 390, 394-95 (9th Cir. 1956). The regulation defines "operated on an

established line" as having three elements: (a) operated with some degree of

regularity, (b) operated between definite points, and (c) the operator maintained

and exercised sufficient control.

Only some degree of regularity is required. The regulation itself states

"strict regularity of schedule" is not required nor is it necessary that "the full run is

always made." Treas. Reg. § 49.4263-5(c). During the pertinent time period,

Taxpayer's tours were flown with sufficient regularity to satisfy the regularity
-4-

element. Gray Line, 237 F.2d at 394; Royce v. Squire, 73 F. Supp. 510, 511-13

(W.D. Wash. 1947), aff'd on other grounds, 168 F.2d 250 (9th Cir. 1948).

Regulations establish that the between definite points requirement can be

satisfied by continuous transportation beginning and ending at the same point. 

Treas. Reg. § 49.4261-1(c). Also, satisfying the definite points requirement does

not necessitate "that the full run is always made; that a particular route is followed;

or that intermediate stops are restricted." Treas. Reg. § 49.4263-5(c). Since a

passenger can only purchase the entire tour, the flight should be considered

continuous transportation beginning and ending at the same point. Even if the stop

on the glacier makes each tour two trips--to and from the glacier--the definite

points requirement is satisfied. Although the exact landing spot on the glacier

varies with the conditions of each day, it is sufficiently definite in that the

destination is a particular glacier. Cf. Gray Line, 237 F.2d at 392 (pickup and

dropoff point could vary from the designated locations as long as it was in the

general direction of the route).

Contrary to Taxpayer's contention, being contracted to provide particular

tours does not preclude Taxpayer from satisfying the control element. Taxpayer

still decides what tours to offer, when to schedule flights, the route to take, and
-5-

where to land. It also decides the maximum number of passengers allowed and

whether to cancel a flight for insufficient sales.

The sightseeing flights at issue were operated as an established line and

therefore are subject to the Transportation Tax.

The Transportation Tax is payable by the purchaser of transportation. I.R.C.

§ 4261(d). The provider of transportation is to collect the tax and pay it over to the

government. Internal Revenue Code § 4263(c) provides, if the Transportation Tax

is not collected from the purchaser, "under regulations prescribed by the

Secretary," the carrier shall pay the tax to the government. As the carrier,

Taxpayer was required to pay the Transportation Tax even though it was not

collected. Taxpayer contends it is not so required because the Secretary never

implemented the related regulations. In certain situations, a tax statute will not be

enforceable until related regulations required by the statute are issued. In

determining whether implementing regulations are a precondition to enforcement,

the Tax Court has looked for explicit language supporting such a conclusion, has

considered legislative history, and has considered whether the statute can be

applied without further explication in a regulation. See Francisco v. Comm'r,

119 T.C. 317, 322-23 (2002), aff'd on other grounds, 370 F.3d 1228, 1230 n.1

(D.C. Cir. 2004). The language of the statute and its legislative history do not
-6-

establish that regulations are a precondition to applying § 4263(c). Further,

§ 4263(c) states a straightforward requirement that, when the Transportation Tax is

not collected, the carrier for the first segment must pay it. There is already a

procedure in place for computing the Transportation Tax and paying it to the

government after it is collected from the purchaser of transportation. Additionally,

nothing in § 4263(c) requires that the government first attempt to collect the

Transportation Tax from the purchasers of the tours.

Taxpayer contends a 1994 audit estops the government from contending the

Transportation Tax applies to tours provided in 2001 through 2004. Estoppel of

the government, however, requires inter alia a showing of a deliberate lie or a

pattern of false promises. Socop-Gonzalez v. INS, 272 F.3d 1176, 1184 (9th Cir.

2001) (en banc). Taxpayer has not satisfied that requirement for estoppel. 

Alternatively, Taxpayer contends that fairness requires that the Transportation Tax,

which has not been collected from purchasers, be applied only prospective to the

2005 audit determination. Regulations, however, do not require prospective

application when a prior audit determination is inconsistent with a later audit

determination. Retroactive application of a new ruling is only called for when

certain requirements are satisfied regarding a change from a prior regulation,

revenue ruling, written ruling of the National Office, or a letter determination. See
-7-

I.R.C. § 7805(b); Treas. Reg. § 601.201. The retroactivity rules do not apply to

determinations made by agents as part of an audit and, even if the retroactivity

rules were applicable, Taxpayer has not shown that the agent who made the 1994

determination was aware of all material facts or that facts did not change between

1994 and 2001.

Taxpayer contends IRS's tax assessment was inaccurate and, therefore, the

government is now precluded from proving the correct amount of Transportation

Tax. The government concedes there were some inaccuracies and that factual

disputes exist as to the amount due. The government, however, is not precluded

from proving an amount is due other than the figure set forth in the assessment. At

most, the assessment would lose its presumption of correctness and the burden

would shift back to the government to prove the amount of tax due. See In re

Olshan, 356 F.3d 1078, 1084 (9th Cir. 2004).

Taxpayer contends the government cannot impose any penalty because, in

light of the 1994 audit determination, Taxpayer's failure to collect and pay the

Transportation Tax was not willful. The government contends it can impose a

§ 6651(a)(2) failure-to-pay penalty, which does not require willfulness. A

§ 6651(a)(2) penalty, though, is not added to the tax if it is shown the failure to pay
-8-

"is due to reasonable cause and not due to willful neglect." Whether facts support

the imposition of this penalty is left for the district court to determine on remand.

The judgment of the district court is vacated and the case remanded for a

determination of the amount of Transportation Tax due and any related penalty.

VACATED AND REMANDED.
