OPINION
After the ad valorem tax payment owed by Tenaska Frontier Partners, Ltd., was returned as undeliverable for insufficient postage, appellee Bill Sullivan — in his capacity as Grimes County tax collector— marked Tenaska’s payment as delinquent and assessed $159,158.66 in penalties and interest. The trial court upheld the assessment by summary judgment, and Te-naska appealed. We affirm.
BACKGROUND
Tenaska owns real property in Grimes County that is subject to ad valorem taxation. On January 30, 2006, Tenaska attempted to pay its 2005 taxes by mailing a check in the amount of $2,273,695.59 in an envelope properly addressed to the Grimes County Appraisal District (“GCAD”), and bearing a 39-cent first-class stamp. Because of the weight of the parcel, however, the correct amount of postage owed was 63 cents. Accordingly, on February 4 the envelope was returned to Tenaska, marked as undeliverable because of the 24-cent postage deficiency. On February 7, Te-naska re-sent its payment, which the appraisal district received on February 8th. Because a preceding year’s tax payments must be made on or before February 1 of the following year, 1 Sullivan posted this February 7 payment as delinquent and assessed $159,158.66 in penalties and interest. 2 Under protest, Tenaska paid the ad *736 ditional assessment and applied for a tax refund. 3 Sullivan denied the refund application, and Tenaska filed suit against Sullivan, Grimes County, and Anderson-Shiro Independent School District.
The parties filed cross-motions for summary judgment. On November 9, 2007, the trial court denied Tenaska’s summary judgment motion, and granted the appel-lees’ motion. This appeal followed. Te-naska now asks us to hold that a tax payment mailed with insufficient postage is nonetheless timely under section 1.08 of the Tax Code. We decline this invitation, and affirm the trial court’s judgment.
STANDARD OF REVIEW
Summary judgments are reviewed de novo.
Valence Operating Co. v. Dorsett,
TIMELINESS OF TENASKA’S TAX PAYMENTS
The Tax Code provides that a party may mail a tax payment, and that such payment is considered timely if:
(1) it is sent by regular first-class mail, properly addressed with postage prepaid; and
(2) it bears a post office cancellation mark of a date earlier than or on the specified due date and within the specified period or the property owner furnishes satisfactory proof that it was deposited in the mail on or before the specified due date and within the specified period.
Tex. Tax Code Ann. § 1.08 (Vernon 2008). The use of the word “and” indicates that a taxpayer must comply with
both
subsections (1) and (2) for its mailed payment to be timely.
See In re Brookshire Grocery Co.,
The February 7 payment was sent by UPS, not first-class mail, and did not bear a post office cancellation mark dated on or before February 1, the due date for Tenaska’s tax payment. The February 7 payment, then, was not timely under section 1.08.
See id.; see also Tex. Workers’ Comp. Comm’n v. Hartford Accident & Indem. Co.,
Viewed in the light most favorable to Tenaska, the envelope containing the January 30 payment bore a post office cancellation mark of January 30, 2006, and therefore satisfied section 1.08(2). 4 See *737 Tex. Tax Code Ann. § 1.08(2). The first payment also appears to have been properly addressed, 5 and was affixed with a first-class stamp. The crux of this dispute, then, is whether insufficient postage constitutes “postage prepaid” under section 1.08(1). We hold that it does not.
The construction of a statute is a question of law that we review de novo.
State v. Shumake,
Although the term “postage prepaid” appears in at least forty-five Texas statutes, the Legislature has blessed neither “postage” nor “postage prepaid” with a statutory definition. When the Legislature fails to define a word or term, courts will apply its ordinary meaning.
See Monsanto Co. v. Cornerstones Mun. Util. Dist.,
Tenaska suggests that “postage” is defined as “the charge for mailing an item,” and “the stamps, labels, or printing placed on an item to be mailed as evidence of payment of this charge.” The American HERITAGE DICTIONARY OP THE ENGLISH LANGUAGE 1068 (4th ed.2000). Similarly, Black’s Law Dictionary defines “postage” as the “charges for postal service.” Black’s Law Dictionary 1166 (6th ed.1990). “Prepay,” not surprisingly, means “to pay or pay for beforehand.” American HeRItage Dictionary, at 2074.
The undisputed summary-judgment evidence shows that the charge for the U.S. Postal Service to mail Tenaska’s January 30 tax payment was 63 cents. Tenaska did not prepay this charge, and, so, the postal service refused to deliver the parcel. “Postage prepaid,” by its plain meaning, requires full payment of the postal charges. Because its payment was not sent with “postage prepaid,” Tenaska’s January 30 payment did not comply with section 1.08(1).
This conclusion comports with the common-law treatment of mailings sent with insufficient postage.
See Wesco Distrib., Inc. v. Westport Group, Inc.,
Tenaska contends, however, that we should liberally construe a punitive taxing statute in the taxpayer’s favor, citing
Bullock v. Statistical Tabulating Corp.
Tenaska does not argue that the term “postage prepaid” is ambiguous; to the contrary, Tenaska exhorts us to adopt the ordinary meaning of the term. Because section 1.08 is unambiguous, we do not consider rules of construction.
See Fitzgerald v. Advanced Spine Fixation Sys., Inc.,
Even were we to construe section 1.08 liberally, a liberal construction does not permit us to do violence to the statutory language.
Wesco,
We must also presume that the Legislature intended a reasonable result.
See Wesco,
Tenaska denies an improper motive to avoid paying taxes, and undoubtedly correctly asserts that its attachment of deficient postage was an “unintentional error.” However, it is up to the Legislature, not this court, to change the plain meaning of the Tax Code.
See Polaris Inv. Mgmt. Corp. v. Abascal,
Tenaska raises a second issue contending that, because the additional assessment was erroneously imposed, it was entitled to a refund under section 31.11 of the Tax Code. Because of our resolution of Tenas-ka’s first issue, we need not reach this second issue.
CONCLUSION
Accordingly, we affirm the summary-judgment orders of the trial court.
