The question in this appeal is whether appellant N. F. Sorg, by permitting customers of area merchants to park without charge on his property, is operating a “parking lot” under our retail sales tax law. If so, Sorg must pay tax on sums contributed by those merchants for care, maintenance and use of the lot. District court affirmed the Department of Revenue director’s order sustaining the sales tax assessment. We reverse.
Section 422.43, The Code 1975, imposes a three percent tax upon gross receipts from, among other things, the rendering, furnishing, or performing of certain enumerated services. The list of services includes “parking lot.”
“Parking lot” is not statutorily defined. See
Scott County Conservation Bd.
v.
Briggs,
*131 Parking lots. Persons engaged in the business of providing parking space for any vehicle are rendering, furnishing or performing a service, the gross receipts from which are subject to tax, irrespective of the method of collection utilized. “Parking lots” shall include any facility used primarily for parking vehicles, whether an outdoor lot or building. “Parking lots” shall also include any parking facility provided by the lessor of a building to his lessees if the lessor makes a separate charge for the parking space above and beyond the rental charge for other space in the building. “Parking lots” shall also include any facility used primarily for parking vehicles, even if such facility is used seasonally or for even shorter duration, such as providing parking space at the time of a show, fair, carnival or similar event.
On the basis of § 422.43 as interpreted by rule 26.35, the Department in 1976 assessed Sorg with a $595.50 sales tax liability (plus interest, penalty and fees) based on gross receipts from 1971 through 1975. Sorg’s protest was upheld by a Department hearing officer, but the Department director reversed and sustained the assessment. Sorg appeals district court’s affirmance of that decision.
There is little factual dispute. Commencing in 1945 Sorg operated a pharmacy in Marion. Later he realized he must have off-street parking to compete with shopping centers established in adjoining areas. In 1965 he and other nearby merchants considered buying a vacant lot adjoining the pharmacy. When collective action fell through, Sorg purchased the lot himself. He improved it for parking by paving and marking off 22 parking spaces.
Since then, however, merchants have contributed varying monthly sums to Sorg for the care and maintenance of the lot. There have been no written or oral leases. In 1975 Sorg sold the pharmacy business but retained ownership of the real estate. Sorg testified the new proprietor and six other businesses have been paying him monthly sums totaling almost $900. All persons have been allowed to park on the lot and no car has ever been towed away.
Sorg basically makes two arguments. He contends the Department exceeded its authority in adopting rule 26.35, which admittedly reaches him, because the legislature did not intend to tax under these circumstances. He also contends rule 26.35 as applied violates equal protection by exempting lessors who receive rental payments covering both business space and parking lot rights — for example, shopping mall owners.
I. Our review of this agency action is governed by the Iowa Administrative Procedure Act (IAPA), chapter 17A, The Code. § 17A.19;
City of Davenport v. PERB,
The rule-making authority of the Department is limited to “rules not inconsistent with the provisions of this chapter.” § 422.68(1). Adoption of administrative rules which are at variance with statutory provisions or which amend or nullify legislative intent exceeds the Department’s authority.
Schmitt,
Rule 26.35 represents the Department’s interpretation of § 422.43’s unadorned reference to parking lots. Although we should give weight to Department’s interpretation, see
Iowa Nat. Indus. Loan Co. v. Iowa State, Etc.,
Because the legislature did not define what it meant by “parking lot” we must arrive at its intent in this taxing statute by application of established rules of construction.
Generally, statutory words are presumed to be used in their ordinary and usual sense and with the meaning commonly attributable to them.
Amos v. Prom, Inc.,
However, in the case before us the words under consideration appear in a taxing statute imposing a sales tax on gross receipts paid a “retailer,” due when parking lot service is furnished the “ultimate user.” See §§ 422.42(5), (6) & (13). In this narrower context of parking for which a charge is paid, we believe the public concept of a “parking lot” is an outdoor lot for parking vehicles where a charge is imposed, at the premises and on the vehicle’s driver, for the privilege of parking a vehicle for a fixed interval. See
Bedford v. Johnson,
102 Colo, at 209,
Our determination it was the legislature’s intent to limit its tax to the operations just described is reinforced by an examination of the other “services” itemized in the same statutory sentence. Under the applicable rule of
noscitur a sociis,
the meaning of a word in a statute is ascertained in light of the meaning of words with which it is associated.
Wright v. State Bd. of Engineering Examiners,
Excluding the contributions Sorg receives from the imposition of sales tax conforms to an even more basic principle: “Taxing statutes are strictly construed against the taxing body — liberally in favor of the taxpayer. It must appear from the language of the statute the tax assessed against taxpayer was clearly intended.”
Scott County Conservation Bd. v. Briggs,
Our interpretation of the relevant statutory language leads us to conclude that the legislature did not intend to impose sales tax in this situation. The Department’s rule 26.35 interpretation of “parking lot,” in our view, sweeps beyond the area the legislature intended to reach with this sales tax on services. To this extent we find the rule inconsistent with § 422.43. It follows the Department exceeded its authority in adopting this rule and in applying it in the case before us. § 17A.19(8)(b). This agency action cannot stand.
II. The above holding obviates any necessity to consider Sorg’s other grounds for reversal.
We reverse and remand to district court for further orders consistent with this opinion.
REVERSED AND REMANDED.
