470 P.3d 656
Ariz. Ct. App.2020Background
- Swift Transportation, a large trucking company, purchased diesel and paid "advance" fuel taxes collected by vendors under a statutory presumption that fuel would be used to propel vehicles on Arizona highways.
- Arizona law lets purchasers rebut that presumption: ADOT may refund fuel taxes if the fuel was used for a non-highway purpose, but those gallons then become subject to Arizona use tax unless exempt.
- ADOT approved Swift’s fuel-tax refund application: ADOT offset the calculated use tax ($190,836.39) against the fuel-tax refund and paid Swift the difference; Swift acknowledged it had used fuel in ways that triggered use tax liability.
- Swift then sought a refund of the use-tax offset from the Arizona Department of Revenue (ADOR), arguing the fuel remained "subject to" fuel tax at the point of sale and thus exempt from use tax under A.R.S. § 42-5159(A)(5).
- ADOR denied the refund; Swift sued in Arizona Tax Court; the court granted ADOR’s Rule 12(b)(6) motion to dismiss. Swift appealed and the Court of Appeals affirmed.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether dismissal under Ariz. R. Civ. P. 12(b)(6) was proper | Swift: dismissal premature; notice pleading protects claim | ADOR: claim raises pure legal/statutory question susceptible to determination on the pleadings | Court: dismissal proper—claim presented a pure statutory-interpretation issue resolvable as a matter of law |
| Whether diesel fuel remains exempt from use tax after ADOT refunds advance fuel taxes (meaning "subject to" fuel tax is fixed at sale) | Swift: "subject to" should be determined at point of sale; advance payment makes fuel permanently "subject to" fuel tax, so use tax exemption survives any later refund | ADOR: refund removes the fuel’s status as "subject to" fuel tax; once refunded, use tax applies and ADOT must offset use tax from refund | Court: Adopted ADOR’s reading—fuel is not permanently "subject to" fuel tax; after ADOT refunds fuel tax based on actual non-highway use, the fuel is no longer "subject to" fuel tax and is subject to use tax; affirmed dismissal and judgment |
