OPINION

I. FACTUAL AND PROCEDURAL HISTORY

In November 2010, AT&T Mobility II LLC and Chattanooga MSA LP, (herein ―AT&T‖), filed separate claims with the Tennessee Department of Revenue (―Department‖)

p ursuant to Tenn essee Code Ann otated § 67

- 1

- 1802(a), seeking a total refund of $24,038,222.38, plus interest, for the sales tax on Internet access services AT&T mistakenly charged its customers from November 1, 2005 through September 7, 2010. 1 With the ref und claims, AT&T provided a list of nearly 800,000 Tennessee customers 2 from whom it had erroneously collected sales taxes and identified the amount it had collected from each customer, as well as a list ―showing how much tax overall for that particular mo nth for that particular jurisdiction was collected in error.‖ 3 As more fully explained infra , the parties worked together for more than three years to provide additional information the Commissioner of Revenue (the ―Commissioner‖) needed to complete the review. Because the refund claims were not resolved within six months of filing, they were deemed denied by operation of § 67

- 1

- 1802(b)(2). AT&T filed complaints pursuant to Tenn essee Code
Ann otated §67

- 1

- 1802(c)(1) on behalf of both entities in Davidson County Chancery Court on November 8, 2011; the suits were consolidated by the chancellor.

1 AT&T‘s refund claim was necessitated by a settlement AT&T had reached in a class action lawsuit brought by its customers premised upon the Internet T ax Freedom Act, PL 105

– 277, October 21, 1998, 47 U.S.C. § 151 note. The settlement required AT&T to seek refunds of the sales taxes and transfer all refunded monies
into an escrow account for the benefit of the settlement class.

2 This customer figure c omes from the testimony of Scott Adams, lead tax accountant at AT&T. At oral argument, counsel for AT&T said the number of customers affected in Tennessee was 735,223.

3 This quotation is from the testimony of Mr. Adams. In the course of the hearing, counsel for AT&T filed Exhibit 1, which contains three DVDs containing what counsel called ―customer

- identifying information‖; the court placed the exhibit under seal. Eac h DVD contained identical files, which Mr. Adams testified ―contain the two spreadsheets . . . the one customer detail showing how much tax was overcollected by customer and
the second one by jurisdiction by month.‖ For each disc contained in Exhibit 1, we were able to access an index which shows four files. The contents of the files are password protected, and neither the record nor the transcript of the trial contains the password; thus we are unable to view the lists themselves. In our analysis we
ha ve relied on the testimony of the witnesses relating to these two data files, specifically Mr. Adams and Bill Stinson, tax auditor at the Department of Revenue.3

In June 2012

, AT&T amended the refund claim after the parties agreed that $1.8

m illion of the amount sought was barred by the applicable statute of limitations. On May 15, 2014, the Commissioner issued checks to each AT&T entity for refund of the taxes collected and interest, and the next day the parties filed a joint motion to extend the disposition date, in which they represented to the court that ―the Defendant Commissioner of Revenue has granted the Plaintiffs‘ refund claims and has issued refund checks that resolve most of the amounts at issue,‖ and that they were ―continuing to work together to resolve any remaining issues and amounts that may be due the Plai ntiffs.‖ In September 2014, the Commissioner issued additional checks to each entity for a refund of taxes and interest; the total amount paid by the Commissioner was $19,299,854.77 in refunds and $62,293.49 in interest. In an order entered three days be fore trial, the court found that ―[m]ost issues have been resolved, but issues involving pre

-

judgment interest remain to be tried.‖

A bench trial was held on October 6, 2014, and five witnesses testified: Scott Adams, lead tax accountant at AT&T; and Depa rtment employees Bill Stinson, an auditor ; Rose McClurkan and Hal Jones, tax audit managers ; and Britt Wood, tax audit supervisor. Twenty

- two exhibits were admitted into evidence, including a stipulation of facts, signed by counsel for both parties, which stated, ―The amount of interest remaining in dispute is $4,696.694.29.‖

After ruling from the bench on April 23, 2015, the chancellor entere d a final order on May 15, 2015

, incorporat ing the transcript of t he oral ruling and making the following findings of fact:

1. In November 2010, Plaintiffs, AT&T Mobility II LLC and Chattanooga MSA LP, filed claims for refund with Defendant, Richard H. Roberts, Commissioner of Revenue for the State of Tennessee, seeking tax refunds in excess of $24 million for sales taxes that Plaintiffs had collected
from their customers in error.

2. The Commissioner continued to review Plaintiffs ‘ claims for refund after this action was filed in November 2011, and in May and September 2014, the Commissioner paid refunds to Plaintiffs in the total amount of $19,362,148.28, consisting of tax of $19,299,854.79 and interest of $62,293.49.

3. At trial, Plaintiffs sought additional interest in the amount of $4,696,694.29 on the sales tax refunds paid to Plaintiffs by the Commissioner based upon the interest provision for court

- ordered tax refunds found at Tenn. Code Ann. § 67

- 1

- 801(b)(2).4 4. The Court finds that the Commissioner determined that Plaintiffs were entitled to the sales tax refunds following an administrative review of
Plaintiffs ‘ refund claims. This Court did not order the refunds.

5. Interest therefore began to accrue beginning forty

- fiv e days from the date that the Commissioner received proper proof to verify that the refunds were due and payable, as provided in Tenn. Code Ann. § 67

- 1

- 801(b)(1).

6. The Commissioner received proper proof to verify that the refunds were due and payable on March 19, 2014, and properly paid interest beginning forty

- five days from that date, as required by Tenn. Code Ann. § 67

- 1

- 801(b)(1).

7. The Commissioner has therefore paid all of the interest that is due on the sales tax refunds paid to Plaintiffs.

The court denied AT&T ‘ s claim for additional interest in the amount of $4,696,694.29 and assessed costs against AT&T. The chancellor designated the order as a final, appealable judgment pursuant to Tenn. R. Civ. P. 54.02.

AT&T appeals, raising the following issues for our review:

1. Did the Chancellor er r in finding that AT&T Mobility‘ s refunds were determined ―by administrative review‖ pursuant to Tenn. Code Ann. § 67

- 1

- 801(b)(1) and not refunds paid by court order under Tenn. Code Ann. §
67

- 1

- 801(b)(2), thus denying AT&T Mobility‘s claim for additional interest of $4,696,694.29?

2. Did the Chancellor err in holding that the Commissioner did not receive ―proper proof‖ with respect to whether AT&T Mobility‘s refunds were due and payable until March 19, 20 14, thus denying AT&T Mobility‘s claims for additional interest of $4,696,694.29?

3. Did the Chancellor err in assessing court costs against AT&T Mobility?

Pursuant to Tenn essee Code Ann otated § 67

- 1

- 1802(a)(1)(A), the Commissioner is empowered to refund to taxpayers ―all taxes collected or administered by the commissioner that are, on the date of payment, paid in error or paid against any statute, rule, regu lation, or
clause of the constitution of this state or of the United States.‖ Such a claim must be filed with the Commissioner ―within three (3) years from December 31 of the year in which the payment was made.‖ Tenn. Code Ann. § 67

- 1

- 1802(a)(1)(A). 5 Upo n receiving a refund claim, the Commissioner is to determine whether a refund is warranted. Tenn. Code Ann. §
67

- 1

- 1802(b)(1) (2011). If the Commissioner has not made the decision within six months

, ―the claim shall be deemed to be denied for the purpose of filing suit in chancery court.‖ Tenn. Code Ann. § 67

- 1

- 1802(b)(2). To challenge the denial or deemed denial of a refund claim, a taxpayer must file suit within one year of the date the claim was filed with the

04

– 03, which indicated that ―Internet access is no longer considered a taxable  ̳telecommunication service‘
under Tennessee law.‖ Tenn. Code Ann. §67

- 6

- 102(93)(B)(vi) (2010) reflects the exclusion of Internet access
from the definition of ―telecommunications services.‖

5 As a prerequisite to filing, the taxpayer must have ―refunded or credited the sales or use tax to its customers.‖

Ten n. Code Ann. § 67

- 1

- 1802(a)(1). Although there is no proof in the record before us that AT&T satisfied this requirement, the record contains AT&T‘s representations regarding the class action lawsuit‘s settlement agreement, including the following language :

4. Settlement Class Acknowledges AT&T Mobility Satisfies Any Pre

- Payment Requirement

The Settlement Class has acknowledged that its members have already received effective payment of the refund amounts sought in this Refund Claim by virtue of AT&T Mobi lity‘s assignment of refund rights to the Settlement Class and its obligation to transfer all refunds received to the Settlement Class, under the terms of the Settlement Agreement and under the supervision of the United States District Court for the Northe rn District of Illinois.

In light of AT&T Mobility‘s obligation to pay the refunded or credited Internet Taxes received by AT&T Mobility to the Escrow Accounts, the Settling Parties agree that AT&T Mobility has assigned and refunded to the Settlement Cla ss all Internet Tax refunds to be sought pursuant to the Settlement Agreement.

The Settlement Class thus waives any requirement that AT&T Mobility pay cash refunds to the Settlement Class prior to obtaining a refund or credit from this taxing jurisdiction

.

The Commissioner raised n o issue before the trial court or on appeal regarding the requirement to refund or credit the taxpayer‘s customers.7

- 1802( c)(1). Trial of the suit is de novo by the chancery court. Tenn. Code Ann. § 67

- 1

- 1802(c)(2).

When a refund is due, the taxpayer is entitled to interest on the amount of the refund.
Tenn. Code Ann. § 67

- 1

- 801(b). The date on which interest begins to accrue depends upon
how the claim is resolved. ―When it is determined by administrative review ‖ that a refund is due, interest ―shall be added to the amount of refund or credit due, beginning forty

- five (45) days from the date the commissioner receives pr oper proof to verify that the refund or credit is due and payable.‖ Tenn. Code Ann. § 67

- 1

- 801(b)(1). On the other hand, ―when it is determined by court order that a person is entitled to a refund or credit of any tax collected or administered by the comm issioner, interest shall be added to the amount of refund or credit due, beginning: (A) Forty

- five (45) days from the date of filing a claim for refund, pursuant to § 67

- 1

- 1802(a) . . .‖ Tenn. Code Ann. § 67

- 1

- 801(b)(2)(A).

The threshold issue in this appeal is whether, for purposes of the calculation of interest, the refund resulted from the Commissioner‘s processing of the claim or from court adjudication. This involves the interpretation of Tenn essee Code Ann otated § 67

A. Construction and Application of Tenn. Code Ann. § 67

- 1

- 801(b)

Tenn essee Code Ann otated § 67

- 1

- 1804 provides that the ―procedure established by [Part 18] i s the sole and exclusive jurisdiction for determining liability for all taxes collected or administered by the commissioner of revenue.‖ As noted above, the amount of interest on
a refund is to be determined in accordance with Tenn essee Code Ann otated § 6 7

- 1

- 801. ―Statutes that are part of a broad statutory scheme should be interpreted in pari materia, so as to make that scheme consistent in all its parts.‖ Najo Equip. Leasing 477 S.W.3d at 769 (citing Wells v. Tenn. Bd. of Regents , 231 S.W.3d 912, 917 (Tenn. 2007); Lyons v. Rasar, 872 S.W.2d 895, 897 (Tenn. 1994); State v. Allman, 167 Tenn. 240, 68 S.W.2d 478, 479 (Tenn. 1934)). ―Our analysis must involve the statute and the relevant counterparts as a whole, and not just one claus e of the statute.‖ Id. (citing Shore v. Maple Lane Farms, LLC, 411 S.W.3d 405, 420 (Tenn. 2013); State v. Turner, 913 S.W.2d 158, 160 (Tenn.1995).

AT&T urges that we adopt a construction of Tenn essee Code Ann otated §§ 67

- 1

- 1802
and 1804 that would hold that any audit work done by the Commissioner after suit has been filed ―cannot be construed to constitute an  ̳administrative review‘‖; accordingly, AT&T argues that the ultimate resolution of this case was in chancery court and interest is to be awarded p ursuant to Tenn essee Code Ann otated § 67

- 1801(b)(2). Upon our review, however, nowhere do the statutes dictate that the Commissioner‘s authority to conduct an administrative review process expire s when suit is filed; we thus decline to adopt the

construct ion urged by AT&T.8

AT&T preserved its right to challenge the Commissioner‘s determination under

Tenn essee Code Ann otated §67

- 1

- 1802(c) by filing suit within one year of filing the refund claim. At the request of the parties, the chancellor extended the d isposition date for the case numerous times in order to allow the review of the refund claim to be completed. The record shows that the process resulted in the refund that was paid in May and September 2014. When the case progressed to trial, the only is sue for the court to resolve was that presented by the application of Tenn essee Code Ann otated §67

- 1

- 801(b), i.e., the date at which interest began to accrue. The trial court did not adjudicate AT&T‘s entitlement to a refund or the amount of the refund, an d, other than the matter of interest, AT&T did not challenge the Commissioner‘s decision. With respect to the issue presented to it for resolution, the trial
court held that ―the Commissioner determined that Plaintiffs were entitled to the sales tax
refun ds following an administrative review of Plaintiffs‘ refund claims. This Court did not
order the refunds.‖

Upon the record presented, no action by or order of the court resolved the refund claim; thus Tenn essee Code Ann otated § 67

- 1

- 801(b)(2) does not a pply. T he Commissioner granted the r efund after an extensive review and the claim was resolved through the
administrative process. 6 B y operation of Tenn essee Code Ann otated § 67

- 1

- 801(b)(1),
interest on the refund is calculated from the date AT&T provided proper proof of the claim to the Commissioner. We proceed to address this issue

.

B. Proper Proof of the Refund Claim

Prior to and while the suit was pending, the parties were successful in determining the
amount of the refund, which the Commissioner paid, along with the portion of interest

6 AT&T and amicus urge that we adopt a bright

- line rule that, upon the filing of suit in chancery court after the denial or deemed denial of a refund claim, the Department‘s administrative review process is terminated and the judicial process is commenced. In support of this position, AT&T relies on Snake Steel, Inc. v. Farr

, Tenn. Ch. Ct, Davidson County, No. 1 0

- 435

- I (Nov. 29, 2011), wherein the taxpayer filed suit under Tenn. Code Ann. § 67

- 1

- 1802 after the claim was deemed denied and prior to the completion of the Commissioner‘s review. The Commissioner refunded overpaid taxes

, and the court held that intere st beginning 45 days from the filing of the refund claim was owed to the taxpayer because ―[a]fter the refund claim is deemed denied, and most certainly after suit has been filed, it is not possible under the intent of the law, as provided in T.C.A. § 67

- 1

- 801(b)(1), for the Claim to still be under administrative review.‖ This argument was presented at the trial court and rejected, with the court stating in the final order that the analysis in Snake Steel ―was more broad in scope than was necessary.‖ For the reasons set forth in this opinion, we find the argument unavailing.

In like manner, we reject AT&T‘s argument that Tenn essee Code Ann otated § 67

- 1

- 1804 vests sole and exclusive jurisdiction over refund claims that have been deemed denied due to the passage of time. T he statute, which states that the procedure set forth in Part 18 is ―the sole and exclusive jurisdiction for determining liabil ity for all taxes collected or administered by the statute‖ incorporates both the administrative processing of a refund claim and the court process available to challenge the Commissioner‘s determination. The statute is not internally inconsistent and doe s not operate to divest the Commissioner, once suit has been filed, of the authority to continue to review a refund claim.9

allowed by the statute consistent with the Commissioner‘s determination that interest began to accrue in March 2014, when AT&T provided the final invoices. The case proceeded to
trial on the question of whether the interest began to accrue 45 days from the filing of the claim in November 2010, as AT&T contended, or as the Commissioner had determined. The chancellor held that ―[t]he Commissioner received proper proof to verify that the refunds were due and payable on March 19, 2014, and properly paid interest beginning forty

- five days from that date, as required by Tenn. Code Ann. § 67

- 1

- 801(b)(1).‖

AT&T argues that the chancellor ―erred in interpreting the  ̳proper proof‘ standard o f Tenn. Code Ann. §67

- 1

- 801(b)(1) as only being met after a taxpayer provides information responding to the last audit inquiry that the Commissioner chooses to make.‖ AT&T states that ―[t]he evidence presented in the trial below prove[s] that, as of recei ving the Nov. 9, 2010 Refund Claims, the Commissioner had the proper proof necessary to verify that the
refunds were due.‖ 7 The Commissioner argues that the refund could not be made ―based upon the initial data files provided by AT&T, which were summary i n nature and could not be correlated to AT&T‘s customer invoices.‖ We review the determination of when proper proof was received as a question of fact and is accordingly reviewed with a presumption of correctness. Tenn. R. App. P. 13(d).

―Proper proof‖ is not defined in the tax statutes. Tenn. Code Ann. § 67

- 1

- 1802(a)(1)(A) requires that a refund claim ―must set forth each ground upon which a refund is claimed, the amount of such refund, the tax period, the tax type, and information reasonably sufficien t to apprise the commissioner of the general basis for the claim.‖ Tenn. Code Ann. § 67

- 1

- 801(b)(1), the interest provision we have held is applicable, provides:

When it is determined by administrative review that a person is entitled
to a refund or cred it of any tax collected or administered by the commissioner, and such person is not a debtor as defined in § 67

- 1

- 1808, interest shall be added to the amount of refund or credit due, beginning forty

- five (45) days
from the date the commissioner receives pr oper proof to verify that the refund or credit is due and payable.

(Emphasis added)

.

The case before us is unique due to the size and the nature of the refund claim, which was complicated by AT&T‘s billing processes; as more fully explained herein, the Department representatives testified as to the significant challenges presented in verifying the
amount of sales tax collected for Internet access . In the oral ruling

, the trial court made

7 There is no citation to the record in support of this statement as required by Tenn. R. App. P. 27(a)(7)(A) or Tenn. R. Ct. App. 6(b).10

extensive findings of fact, no ne of which are challenged by AT&T, including the f ollowing

, which we find particularly pertinent to our analysis :

The plaintiffs complained that the Department demanded data in specific formats and this caused unnecessary delay. The Court finds that the Department was not prepared on the spot to address refunds regardless of the complexity of the industry or the complexity of the errors which were made in paying overtaxes to the Department. It must be remembered that the tax payment was not the result of an assessment made by the Department. The Department was not prepared with a cookie

- cutter response to the plaintiffs who made a huge amount

— paid a huge amount of taxes in error. There was no formulaic solution to the plaintiffs‘ refund claims.

We have thoroughly reviewed the record and conclude that the evidence, specifically the testimony of Scott Adams, Bill Stinson, and Britt Wood as summarized below, supports the court‘s finding.

Mr. Adams testified that he assisted with gathering the informat ion needed to submit
the refund claim , which AT&T provided in the form of ―summary records‖ to th e Commissioner in November 2010 ; and that AT&T submitted a list of the nearly 800,000 Tennessee customers affected and how much they were each charged in sales tax, as well as a list that showed how much tax ― for that particular month for that particular jurisdiction was
collected in error .‖ M r. Stinson, the auditor assigned to the refund claim, testified that when
he looked at the records sent by AT&T, he concluded that he would need more information
from AT&T because he had no way to corroborate the data or reconcile it and thus could not verify the amount

. Mr. Stinson went to AT&T‘s Texas offices in January 2011, and he and
Mr. Adams discusse d performing an audit using a statistical sample of the invoices, rather
than a three

- month block sample advocated by AT&T. 8 The statistical sample model was decided upon in the second quarter of 2011

.

8 Rose McClurkan, a tax audit manager at the Department of Revenue, explained that a statistical sample audit
is:

[A] method of deciding a subset of records to look at other than 100 percent detail of every electronic record received. And we do that by breaking the data set into smaller components, which is called strata[,] which is nothing more than subsets arranged by dollar value, and we assign a range of numbers to pull a random sample from that. . . . [W]e feel it‘s the more reliable method if you‘re not able to look at 100 percent of the records, because that scientific approach has years of study behind it. It‘s impartia l because we‘re using a random number generator[,] and there‘s no auditor making a determination about which specific item to look at. That‘s a great way to represent a large number of records without having to look at them in
detail.11

Mr. Adams testified that in November 2012, AT&T provi ded additional information to the Department so that it could develop its statistical sample request ; after reviewing the data, in March or April of 2013, the auditors requested 962 sample invoices; 730 of those were provided two to three months later. Wi th respect to the 730 samples that were provided, Ms. Wood testified that they only comprised a ―very small portion of the sample,‖ roughly $2,000 worth of cha rges out of the $311,000 charges in the total sample. During Mr. Stinson‘s and Ms. Wood‘s trip t o AT&T‘s offices in Texas in January 2014, AT&T provided 61 more invoices as well as a new data file containing a complete description of the relevant billing codes, which Mr. Stinson said helped ―finalize the audit because [he] wouldn‘t have
been able to get through those last 100 invoices, which was pretty close to 400,000 pages,
without those [billing] codes.‖ T he data from the remaining 100 invoices was compiled and sent to the department on March 19, 2014 ; and Mr. Stinson testified that upon receiving this data, the Department was then in possession of sufficient documentation to make a
recommendation of the refund.

Th is evidence s upports the trial court‘s findings that the data originally provided was
not sufficient for the Commissioner to conduct the review of the refund claim. Mr. Scott
testified that similar data files were provided with ref und claims sent to other states but that
AT&T was asked to and provided invoices in the course of those other state‘s audits. The
Tennessee sales tax refund claim form specifically instructs: ―Attach a schedule and copies of pertinent invoices, resale certificates, and/or exemption certificates, if applicable and credit memo to customer(s). Attach separate sheet if necessary. ‖ AT&T did not include samples of
the millions of inv oices but instead summarize d the taxes charged to each customer

.

The Commissioner‘s staff and AT&T‘s personnel worked together beginning shortly after the claim was filed to identify the information needed to complete the Commissioner ‘s
review of the claim. I n light of the number of Tennessee residents affected and the amount of money at stake in this refund claim, the re is no proof in the record from which to conclude
the Commissioner‘s review was unreasonable

. 9 Under the facts of t his case, the review

Mr. Stinson testifie d as follows about the difference between the two methods of sampling that were
considered in this audit:

A three

- month sample is

– the accuracy can‘t be verified, whereas a statistical sample, you verify it through calculations as far as what the

— the a ccuracy of your results. A three

- month sample is usually used as a convenience when other methods can‘t be used.

9 Ultimately, the review process engaged in by the parties resulted in AT&T being awarded nearly $5 million less in refunds than it original ly sought. AT&T does not dispute the propriety of the final amount refunded, only the interest awarded. The record makes clear that the parties‘ agreed that the statute of limitations barred some claims and that AT&T reduced its refund claim upon its dis covery that incorrect billing codes had been used, which resulted in inflated amounts being requested in the initial refund claim. These issues, and others, were brought to light during the course of the audit. The trial court found that ―certain billing codes did not constitute data service but were inadvertently included in the refund claim,‖ and that ―the electric spreadsheets12

process was uniquely within the purview of the Commissioner and his auditing staff, as the chancery court is ill equipped to conduct such an audit and conclude that a refund is or is not
due

. AT&T has not cited to proof that preponderates against the court‘s findings, and our
review of the record reveals none. Accordingly, w e conclude that the trial court did not err in finding that proper proof , within the meaning of Tenn. Code Ann. § 67

- 1

- 801(b)(1) was no t supplied un til March 14, 2014

C. The Award of Costs

Conten d ing that its pursuit of interest was ―not only consistent with the applicable statutes, but was also consistent‖ with another decision of the trial court in a different case

, AT&T argues that the trial c ourt erred in awarding court costs against it. Given our holding on the merits, the trial court‘s award of court costs is affirmed.

In light of our disposition of the issues raised on appeal, we decline to award AT&T
its attorneys‘ fees

.

IV. CONCLU SION

In light of the foregoing, we affirm the judgment of the Chancellor in all respects. We remand this matter for further proceedings in accordance herewith.

summaries [submitted with the refund claim] were not accurate.‖ AT&T does not dispute this factual finding. The complexity of this particular refund claim underscores the need for a thorough review.
