Before: BATCHELDER, Chief Judge; GIBBONS and ROGERS, Circuit Judges.

       JULIA SMITH GIBBONS, Circuit Judge. Plaintiff-appellant Ford Motor Company

(“Ford”) seeks approximately $445 million in interest that it believes has accrued on overpayments

of its corporate income taxes. Ford contends that the Internal Revenue Service (“IRS”), under 26

U.S.C. § 6611, was required to calculate overpayment interest from the earlier dates on which Ford

submitted deposits to the IRS, rather than from the later dates on which Ford requested that those

deposits be converted into advance payments of tax. The district court granted the government’s

motion for judgment on the pleadings and denied Ford’s motion for summary judgment, finding

reasonable the government’s interpretation of § 6611—that overpayment interest be calculated only

from the later dates of conversion. For the reasons that follow, we affirm.

                                                  I.

       The facts giving rise to Ford’s legal claims are not in dispute. On September 9 and 27, 1991,

July 6, 1992, and June 23, 1994, Ford submitted remittances to the IRS. In submitting these

remittances, Ford specifically requested that they be treated as deposits in the nature of a cash bond.

Ford made these remittances, amounting to several hundred millions of dollars, after it had been

audited by and received 30-day letters from the IRS which notified Ford of proposed tax deficiencies

incurred during 1983–1989, 1992, and 1994.

       Subsequently, Ford requested that the IRS treat these remittances as advance payments—i.e.,

payments towards proposed (not yet assessed) tax deficiencies—rather than as deposits in the nature

of a cash bond. On December 19, 1994, Ford requested that part of the September 9, 1991 deposit

be treated as an advance payment. One year later, on December 15, 1995, Ford requested that

another portion of its September 9, 1991 deposit; portions of its deposits made on September 27,

1991 and July 6, 1992; and the entire June 23, 1994 deposit also be treated as advance payments.

The IRS obliged, and thus Ford effectively converted its deposits that were held in the nature of cash

bonds into advance payments towards proposed past-due taxes.

       At some point after the deposits were converted, the IRS determined that Ford had in fact

overpaid its taxes for the years in question and issued refunds to Ford. These refunds included the

amount that Ford overpaid and the interest that had accrued on its overpayment. Importantly—and

at the heart of this dispute— the IRS calculated the amount of overpayment interest from the dates

on which Ford requested that its deposits be converted to advance payments (i.e., the “conversion

dates” of December 19, 1994 and December 15, 1995), not from the earlier dates on which Ford

remitted the deposits (i.e., the “remittance dates” of September 9 and 27, 1991, July 6, 1992, and

June 23, 1994).

       On July 10, 2008, Ford filed a complaint seeking approximately $445 million in interest that

had allegedly accrued on overpayments of its corporate income taxes for 1983–1989, 1992, and

1994. The United States moved for judgment on the pleadings pursuant to Federal Rule of Civil

Procedure 12(c). Ford responded and also moved for summary judgment. On June 3, 2010, after

conducting a hearing, the district court granted the government’s motion for judgment on the

pleadings and denied Ford’s motion for summary judgment. Although the district court conceded

that Ford’s argument “may have some merit,” it found reasonable the government’s position that

there could be no overpayment of tax—and therefore no overpayment interest accrual—until Ford

actually converted its deposits to advance payments. Thus, the court held that the government had

correctly calculated Ford’s overpayment interest.

       We review de novo the district court’s grant of judgment on the pleadings and its denial of

summary judgment. Fortney & Weygandt, Inc. v. Am. Mfrs. Mut. Ins. Co., 595 F.3d 308, 310 (6th

Cir. 2010).

                                                  II.

       Corporate tax returns, like individual tax returns, are subject to audit by the IRS. See

generally 34 Am. Jur. 2d Federal Taxation ¶ 70000 (updated 2012). An audit may reveal that the

corporate taxpayer has underpaid or overpaid its taxes for the year in question. If the audit reveals

that a taxpayer has overpaid its taxes, then the taxpayer is entitled to the amount of the overpayment,

plus interest on that overpayment. 26 U.S.C. § 6611(a); see generally 34 Am. Jur. 2d Federal

                                                 -3-

Taxation ¶ 70901 (updated 2012). The “overpayment interest” statute, 26 U.S.C. § 6611, reads as

follows:

       (a) Rate. – Interest shall be allowed and paid upon any overpayment in respect of any
       internal revenue tax at the overpayment rate established under section 6621.

       (b) Period. – Such interest shall be allowed and paid as follows . . .
              (2) Refunds. – In the case of a refund, from the date of the
              overpayment to a date (to be determined by the Secretary) preceding
              the date of the refund check by not more than 30 days, whether or not
              such refund check is accepted by the taxpayer after tender of such
              check to the taxpayer . . . .

26 U.S.C. § 6611(a)–(b)(2) (emphases added). Conversely, if a taxpayer has underpaid taxes, he is

liable for the amount of underpayment plus interest on that underpayment. The “underpayment

interest” statute, 26 U.S.C. § 6601, reads as follows:

       (a) General rule. – If any amount of tax imposed by this title . . . is not paid on or
       before the last date prescribed for payment, interest on such amount at the
       underpayment rate established under section 6621 shall be paid for the period from
       such last date to the date paid.

Id. § 6601(a) (emphases added). Thus, § 6611 (taxpayer entitlement to overpayment interest) and

§ 6601 (taxpayer liability for underpayment interest) are functionally parallel in that they describe

when interest starts and stops accruing.

       Because it can take years for the IRS to complete an audit and resolve any administrative

appeals related to a return, significant underpayment interest can accrue in the interim if a taxpayer

has indeed underpaid. To avoid this possibility, a taxpayer may remit money to the IRS pursuant to

Revenue Procedure 84-58—before any tax liability is assessed—which will stop the accrual of

underpayment interest in the event that the taxpayer is later found to have underpaid. See Rev. Proc.


                                                 -4-
Ford Motor Company v. United States
No. 10-1934

84-58, 1984-2 C.B. 501, superseded by Rev. Proc. 2005-18, 2005-1 C.B. 798. To gain this benefit

and stop potential underpayment interest from accruing, a taxpayer must designate the remittance

as “a deposit in the nature of a cash bond.” Id. §§ 4.02; 5.01. A taxpayer who submits a deposit in

the nature of a cash bond may request the return of the deposit at any time—but if he does so, he will

not be paid interest for the time the IRS had the deposit and he will be liable for interest incurred on

any underpayment from the date of the remittance. In other words, in addition to not earning interest

on his deposit, the taxpayer who requests his deposit’s return will lose whatever interest-stopping

benefits he gained by submitting a deposit in the first place. See id. §§ 5.01, 5.04. Alternatively,

after submitting a deposit in the nature of a cash bond, the taxpayer may request that this deposit be

converted and applied towards an advance payment of a tax—i.e., a tax that has been proposed but

not assessed.1

        There is no dispute Ford designated that its remittances be treated as deposits in the nature

of a cash bond pursuant to Revenue Procedure 84-58, and thus stopped the accrual of any

underpayment interest. Instead, the dispute here involves overpayment interest. Years after Ford

submitted remittances pursuant to Revenue Procedure 84-58, Ford requested that the IRS treat these

deposits as advance payments on its proposed tax liabilities. But then, years after converting Ford’s

deposits to tax payments, the IRS recognized that Ford had in fact overpaid its taxes. The IRS


        1
        It appears that there is no provision of the Revenue Procedures that specifically allows a
taxpayer to request the “conversion” of its deposit to a payment of tax. But the fact that a taxpayer
can request initially that its remittance be treated as a deposit, see Rev. Proc. 84-58 § 4.02, or
otherwise it will be treated as a tax payment, id. § 4.03, supports the logical inference that a taxpayer
may request conversion from deposit to tax payment. And it is undisputed that Ford’s request to
convert its deposits was granted.

No. 10-1934

therefore refunded Ford the amount of overpayment plus interest on that overpayment, calculating

the interest due from the date that Ford requested that its remittances be treated as tax payments.

Ford contends that interest should be calculated from earlier dates—the dates on which it initially

submitted its remittances. Accordingly, we face the following question: does overpayment interest

accrue from the date of the initial remittance or the date when the taxpayer requests the remittance

be treated as an advance tax payment?

                                                 III.

       We begin any statutory-interpretation analysis “by examining the language of the statute itself

to determine if its meaning is plain.” Nat’l Air Traffic Controllers Ass’n v. Dep’t of Transp., 654

F.3d 654, 657 (6th Cir. 2011) (internal quotation marks omitted). “Plain meaning is examined by

looking at the language and design of the statute as a whole.” Id. (internal quotation marks omitted).

“[W]e must interpret statutes as a whole, giving effect to each word and making every effort not to

interpret a provision in a manner that renders other provisions of the same statute inconsistent,

meaningless or superfluous.” Menuskin v. Williams, 145 F.3d 755, 768 (6th Cir. 1998) (internal

quotation marks omitted). Moreover, “[i]n interpreting the meaning of the words in a revenue Act,

we look to the ordinary, everyday senses of the words.” C.I.R. v. Soliman, 506 U.S. 168, 174 (1993)

(internal quotation marks omitted).

       In addition, when interpreting § 6611, we bear foremost in mind that Ford’s challenge

involves construing a waiver of sovereign immunity in a suit for interest against the government.

It is well established that the “no-interest rule” shields the government from liability in suits for

interest unless there is a express statutory waiver of sovereign immunity. Library of Cong. v. Shaw,

                                                 -6-

478 U.S. 310, 317–18 (1986), abrogated by statute on other grounds as recognized in Landgraf v.

USI Film Prods., 511 U.S. 244, 251 (1994); Van Winkle v. McLucas, 537 F.2d 246, 247–48 (6th Cir.

1976); United States ex rel. Angarica de la Rua v. Bayard, 127 U.S. 251, 260 (1888). Where the

government has waived sovereign immunity, we are bound to “strictly construe[]” the waiver, “in

terms of its scope, in favor of the sovereign,” Lane v. Pena, 518 U.S. 187, 192 (1996); to limit such

waivers to their plain language, Ruckelshaus v. Sierra Club, 463 U.S. 680, 693–94 (1983); and to

construe any “ambiguities in favor of immunity.” United States v. Williams, 514 U.S. 527, 531

(1995). Although this strict construction principle does not displace other rules of statutory

construction, Richlin Sec. Serv. Co. v. Chertoff, 553 U.S. 571, 589 (2008), it is not to be taken

lightly: the “no-interest rule provides an added gloss of strictness upon the[] usual rules” governing

waivers of sovereign immunity. Shaw, 478 U.S. at 318.

       Here, the question is not whether Congress has consented to be sued for interest on tax

overpayments; it clearly has. Both § 6611(a) and (b) specifically state that overpayment interest

“shall be allowed and paid.” 26 U.S.C. § 6611(a) (“Interest shall be allowed and paid upon any

overpayment . . . .”); id. § 6611(b) (“Such interest shall be allowed and paid as follows . . . .”).

Rather, the proper question is the scope of that waiver.2 And as the Supreme Court has recently

reiterated, “[f]or the same reason that we refuse to enforce a waiver that is not unambiguously



       2
        This dispute does not involve the mere calculation of interest, where principles of sovereign
immunity arguably might not apply. See J.F. Shea Co.v. United States, 754 F.2d 338, 340 (Fed. Cir.
1985). Rather, it involves whether the government can be sued at all for overpayment interest
accruing from the date of deposit—and therefore necessitates an inquiry into how broadly the
government has waived its sovereign immunity, which is fundamentally a question of scope.

expressed in the statute, we also construe any ambiguities in the scope of a waiver in favor of the

sovereign.” F.A.A. v. Cooper, 132 S. Ct. 1441, 1448 (2012). Thus, for Ford to prevail here, “the

scope of Congress’ waiver [must] be clearly discernable from the statutory text in light of traditional

interpretive tools. If it is not, then we take the interpretation most favorable to the Government.”

Id.3

                                                   A.

        Section 6611 does not define “the date of overpayment” and the tax code generally does not

define the term “overpayment.” Gen. Elec. Co. & Subsidiaries v. United States, 384 F.3d 1307, 1312

(Fed. Cir. 2004). However, the Supreme Court has “read the word ‘overpayment’ in its usual sense,

as meaning any payment in excess of that which is properly due.” Jones v. Liberty Glass Co., 332

U.S. 524, 531 (1947); see United States v. Dalm, 494 U.S. 596, 609 n. 6 (1990) (“The commonsense

interpretation is that a tax is overpaid when a taxpayer pays more than is owed, for whatever reason



        3
          Although the Supreme Court has arguably softened its use of the strict construction principle
since the 1990s, see generally Burch v. Sec’y of Health & Human Servs., No. 99-946V, 2010 WL
1676767, at *5–6 (Fed. Cl. Apr. 9, 2010), the Court has done so only when a party sought to apply
the strict construction principle to a statute or section of a statute entirely separate from the one that
supplied the waiver of sovereign immunity itself. See Gomez-Perez v. Potter, 553 U.S. 474, 491
(2008) (refusing to apply strict construction principle to substantive provision of subsection where
the waiver of sovereign immunity was contained in another subsection); United States v. White
Mountain Apache Tribe, 537 U.S. 465, 472–473 (2003) (holding that where one statute provides for
a waiver of sovereign immunity to enforce a separate statute, the latter statute is not subject to the
strict construction principle). Here, § 6611 itself waives sovereign immunity for interest on tax
overpayments, and both § 6611(a) and (b) specifically state that overpayment interest “shall be
allowed and paid” and contain the key word “overpayment.” Thus, the strict construction principle
applies. See Schortmann v. United States, 82 Fed. Cl. 1, 6 (2008) (finding that the language of §
6611 as a whole constituted a waiver of sovereign immunity “too explicit to be misunderstood”).

or no reason at all.”). But to define “overpayment” with any precision also requires defining

“payment.” And the ordinary, commonsense meaning of “payment” is “the act of paying or giving

compensation: the discharge of a debt or an obligation.” Webster’s Third New International

Dictionary 1659 (1981); Black’s Law Dictionary (9th ed. 2009) (defining payment as “[p]erformance

of an obligation by the delivery of money . . . accepted in partial or full discharge of the obligation”);

see Katkin v. C.I.R., 570 F.2d 139, 142 (6th Cir. 1978) (referring to Webster’s and Black’s

dictionaries in interpreting meaning of “payment” in an unrelated provision of the tax code). Indeed,

when interpreting the statutory predecessor to § 6611, one of our sister circuits adopted exactly this

definition of “payment.” Busser v. United States, 130 F.2d 537, 539 (3d Cir. 1942).

        The government seizes upon the plain meaning of the word “payment,” arguing that there

can be no overpayment until there has actually been a payment—and there was no payment until

Ford requested that its deposits be converted into tax payments. Prior to that point, Ford’s

remittances were, at its own request, treated as deposits in the nature of a cash bond and Ford could

have requested their return at any time. As Revenue Procedure 84-58 § 2.03 clearly states, “[a]

deposit in the nature of a cash bond is not a payment of tax.” Accordingly, the government argues

that it does not owe Ford interest from the date of the original remittances because they were

indisputably made only as deposits, not as payments of any tax obligation.

        Ford counters that the “most appropriate starting point” is not § 6611, but rather § 6601, the

provision that governs underpayment interest. First, Ford contends that these two sections should

be interpreted symmetrically because they both use very similar language, compare § 6601 (“date

paid”), with § 6611 (“date of the overpayment”), and both deal with the accrual of interest on tax

                                                   -9-
Ford Motor Company v. United States
No. 10-1934

payments. Second, Ford notes that under § 6601(a), only a “payment” stops the accrual of

underpayment interest against a taxpayer, and since a deposit in the form of a cash bond stops the

accrual of interest from the date it is remitted, Rev. Proc. 84-58 § 5.01, that deposit must be

considered a payment under § 6601(a). And because a deposit is treated as a payment for

underpayment interest purposes under § 6601, it should also be considered a payment for

overpayment interest purposes under § 6611. In other words, if a mere deposit stops the accrual of

underpayment interest, then a mere deposit must also start the accrual of overpayment interest.

        Both parties’ readings are plausible. The government’s interpretation is grounded in the

ordinary meaning of the terms “date of the overpayment” and “payment.”               However, this

interpretation ignores that the date of remittance is treated as the date of “payment” under § 6601—a

section that uses similar language to § 6611—at least insofar as it stops the accrual of underpayment

interest pursuant to Revenue Procedure 84-58. Conversely, Ford makes a strong case for interpreting

interest accrual under § 6601 and § 6611 symmetrically. Yet Ford ignores a natural reading of “date

of overpayment,” and does not account for the fact that the language the two statutes employ, though

similar, is not identical.4


        4
          Additionally, Ford observes that if the government is correct that a payment only occurs
when a deposit is converted to discharge a debt, then the government has unlawfully neglected to
collect underpayment interest from remitting taxpayers (who later convert their remittances into
payments) for the period from remittance to conversion. This is so, Ford argues, because the IRS
must collect interest owed by taxpayers. See 26 U.S.C. § 6404(e) (establishing circumstances, not
applicable here, under which the IRS can abate interest collection). Ford thus insists that we must
either adopt its definition of “payment,” or find that the IRS has long been violating the interest
statutes.
        We do not view the issue in such stark terms. Congress has explained that prior to amending
the tax code in 2004, the law of the land was that “[a] deposit in the nature of a cash bond is not a

                                                -10-
Ford Motor Company v. United States
No. 10-1934

       In light of the parties’ conflicting, plausible readings of § 6611, we find that the text of the

statute is ambiguous as to when the accrual of overpayment interest begins.

                                                 B.

       Because each of the parties’ interpretations of § 6611 is plausible, it cannot be said that

Congress has “unequivocally expressed” its waiver of sovereign immunity for claims to overpayment

interest accruing between the date a deposit in the nature of a cash bond was remitted and the date

that deposit was converted to an advance tax payment. See United States v. King, 395 U.S. 1, 4

(1969); see also United States v. Nordic Vill., Inc., 503 U.S. 30, 37 (1992) (finding government’s

“plausible” statutory interpretation was “enough to establish that a reading imposing monetary

liability on the Government [was] not ‘unambiguous’ and therefore should not be adopted”);

Siddiqui v. United States, 359 F.3d 1200, 1204 (9th Cir. 2004) (declining to find that Congress had

waived sovereign immunity for punitive damages where statute was subject to two “plausible”

interpretations); Fed. Nat’l Mortg. Ass’n v. United States, 379 F.3d 1303, 1311 (Fed. Cir. 2004)

language at issue [was] ambiguous, subject to two conflicting interpretations”).

at 60 (Comm. Print 2005). That the IRS has long treated deposits as payments for underpayment
interest purposes under § 6601—a practice which benefits taxpayers, which Congress has long
tolerated, and which is neither expressly prescribed nor proscribed by the statutes—does not
necessarily mean that these deposits are “payments” under the interest statutes. Thus, even if we
assume that the two interest statutes should be interpreted symmetrically, Ford’s interpretation of §
6611 does not necessarily prevail.

       Indeed, when we have found a waiver of sovereign immunity in the tax context, Supreme

Court precedent interpreting the specific provision at issue has guided our interpretation. In E.W.

Scripps Co. & Subsidiaries v. United States, 420 F.3d 589, 596–98 (6th Cir. 2005), we concluded

that Congress had waived the government’s sovereign immunity and was subject to district court

jurisdiction with respect to suits for overpayment interest under 28 U.S.C. § 1346(a)(1), a different

provision than the one at issue here. We found that language in § 1346(a)(1), which allowed

taxpayers to recover “any sum alleged to have been excessive or in any manner wrongfully

collected,” represented a waiver of sovereign immunity. Id. at 596 (emphasis added). In finding that

the scope of “any sum” under § 1346(a)(1) extended to interest on tax overpayments, we relied in

no small part upon Flora v. United States, 362 U.S. 145, 149 (1960), a Supreme Court case that had

interpreted the phrase “any sum” in § 1346(a)(1) quite broadly, suggesting that it would include

interest on tax overpayments. E.W. Scripps Co., 420 F.3d at 596–97. Although we noted the general

principle that “taxpayers should be compensated for the lost time-value of their money when they

make overpayments of tax,” 420 F.3d at 597, a principle that provides some support to Ford, we only

did so after grounding our interpretation of “any sum” in Supreme Court jurisprudence. No such

strong foothold exists here. In fact, the most relevant Supreme Court case supports, albeit weakly,

the government.5

        In Rosenman v. United States, 323 U.S. 658, 662–63 (1945), the Court found that the
taxpayer remittances in question were deposits rather than payments, thus providing some support
for the government’s view. However, Rosenman’s import is sharply limited because that case
involved a statute-of-limitations issue rather than an interest-overpayment issue, and construed a
long-defunct tax statute. Thus, as the government conceded at oral argument, Rosenman’s
statements about taxpayer remittances are dicta. In addition, Rosenman held that the remittances in

        Instead, Ford relies heavily on Revenue Procedure 84-58, the only published guidance

bearing on the meaning of “date of the overpayment” in § 6611(b)(1). Needless to say, relying upon

a Revenue Procedure is quite different from relying upon a Supreme Court decision. A revenue

procedure is at most an interpretive aid: it is “well-established that, as a general rule, ‘the I.R.S.’s

Revenue Procedures are directory not mandatory.’” Estate of Shapiro v. C.I.R., 111 F.3d 1010, 1017

(2d Cir. 1997) (quoting Estate of Jones v. C.I.R., 795 F.2d 566, 571 (6th Cir. 1986)). A revenue

procedure does not enjoy the status of a law or regulation and does not bind courts. Xerox Corp. v.

United States, 41 F.3d 647, 657–58 (Fed. Cir. 1994). Rather, it is a “mere internal procedural guide”

that typically does not even bind the IRS itself. See Shapiro, 111 F.3d at 1017–18; see also Riley

v. United States, 118 F.3d 1220, 1222 (8th Cir. 1997). Accordingly, “the ‘failure to comply with [a]

Revenue [Procedure] . . . is not dispositive . . . .’” Shapiro, 111 F.3d at 1017 (quoting Virginia Educ.

Fund v. Comm’r, 799 F.2d 903, 904 (4th Cir. 1986)).

        Two provisions of Revenue Procedure 84-58 are relevant here. The parties agree that under

Revenue Procedure 84-58 § 5.01, underpayment interest stops accruing on the date that a remittance

is submitted to the IRS, regardless of whether the remittance is treated as a payment of tax or a

deposit. However, the parties debate the meaning of Revenue Procedure 84-58 § 5.05, which deals

with when interest starts accruing for the purpose of overpayments. That provision reads:




question could not be payments at least partly because no tax had yet been assessed, see id. at 662,
yet the tax code now explicitly rejects the notion that there can be no payment or accrual of
overpayment interest until a tax is actually assessed, 26 U.S.C. § 6401(c)—further limiting
Rosenman’s relevance here.

       Remittances treated as payments of tax will be treated as any other assessed amount
       and compound interest will be paid on any overpayment under section 6611 of the
       Code. In the event that [a] deposit in the nature of a cash bond is posted to a
       taxpayer’s account as a payment of tax pursuant to subparagraph 3 of section 4.02,
       interest will run on an overpayment later determined to be due only from the date the
       amount was posted as a payment of tax.

Rev. Proc. 84-58 § 5.05.

       In Ford’s view, the first sentence of § 5.05 establishes the general rule that overpayment

interest will be paid on “[r]emittances treated as payments of tax,” whether treated as tax payments

when initially remitted or when later converted from deposits to tax payments. The second sentence

is an exception to this general rule that states that when a deposit is converted to a tax payment

pursuant to § 4.02, a section not applicable here, overpayment interest is determined “only from the

date the amount was posted as a payment of tax,”—i.e., the conversion date. Ford explains that

because “there would be no need for such an ‘exception’ if interest can never begin accruing under

§ 6611 before the conversion date, it follows that the general rule must be that interest does accrue

from the remittance date on a converted deposit.”

       In response, the government argues that because Revenue Procedure 84-58 “does not even

contemplate” a taxpayer’s request to convert a deposit to a tax payment, the only way to understand

the conversion itself is as a “constructive return” of the deposit to the taxpayer followed by his

immediate re-submission of the deposit as a tax payment. Accordingly, when a taxpayer requests

a conversion from deposit to payment, he works an effective return of his deposit, which does not

bear interest, Rev. Proc. 84-58 §§ 2.03, 4.02, followed by an immediate resubmission in the form

of a tax payment, which bears interest from the date it is submitted. In the government’s view, the

first sentence of § 5.05 only applies to remittances that are treated as tax payments when they are

sent to the IRS. Because Ford rendered its remittances as deposits, not as payments of tax, it is not

entitled to interest from the remittance date.

       The government’s interpretation is strained. Under its reading, whenever a taxpayer requests

conversion of a deposit to a tax payment and there is a “constructive return” of this deposit, the

taxpayer should lose any interest-stopping protections gained by remitting the deposit in the first

place. See Rev. Proc. 84-58 §5.01. But this did not occur here: the government did not claim that

Ford, in requesting that its deposits be converted to tax payments, lost any interest-stopping benefits

or owed any underpayment interest as a result of losing these benefits. Indeed, this approach would

seem to undercut the entire purpose behind Revenue Procedure 84-58, which is to “provide[]

procedures for taxpayers to make remittances in order to stop the running of interest on deficiencies.”

Rev. Proc. 84-58 § 1. If a taxpayer loses the interest-stopping benefits of making a deposit by

requesting that the deposit be converted to a tax payment, then there is little incentive to make a

deposit in the first place. In this sense, the government’s interpretation strips away from the Revenue

Procedure the very protection it was designed to furnish.6

       Nonetheless, although Ford’s interpretation of Revenue Procedure 84-58 §5.05 is superior

to the government’s, it is insufficient to render the phrase “date of the overpayment” in 26 U.S.C.


       6
          Furthermore, it appears that the IRS, in a private letter ruling, has contradicted the
interpretation of Revenue Procedure 84-58 it now advances. See I.R.S. P.L.R. 8738041 (June 23,
1987). Specifically, the IRS stated that “[b]ecause the Government will have uninterrupted use of
[a] remittance, the remittance will not be deemed to be returned upon redesignation as a payment of
tax . . . .” Id. This statement appears to cut against the government’s contention that converted
deposits are constructively returned to the taxpayer.

No. 10-1934

§ 6611(b)(1) unambiguous. After all, the Revenue Procedure states and the parties agree that Ford’s

remittances were not payments when they were submitted. Rev. Proc. 84-58 § 2.03 (“A deposit in

the nature of a cash bond is not a payment of tax . . . .”). Thus, the most Ford can say is that its

remittances were treated as payments by the IRS pursuant to Revenue Procedure 84-58 § 5.01 for

purposes of 26 U.S.C. § 6601, and thus these remittances should be treated as payments pursuant

to Revenue Procedure 84-58 § 5.05 for purposes of shedding light on the language used in 26 U.S.C.

§ 6611. In other words, Ford relies heavily upon the Revenue Procedure to support its argument that

§ 6601 and § 6611 should be read symmetrically. But we are unwilling to place so much weight

upon an interpretive aid that binds neither the IRS nor this court. See Shapiro, 111 F.3d at 1017–18;

Xerox Corp., 41 F.3d at 657–58; Jones, 795 F.2d at 571. Revenue Procedure 84-58 is just that—a

statement of procedure or guidance issued by the executive branch. It is far from an expression of

congressional intent as to the scope of a waiver of sovereign-immunity; indeed, it does not even

enjoy the status of an agency regulation. Xerox Corp., 41 F.3d at 657. Thus, however helpful to

Ford, Revenue Procedure 84-58 is too weak an indicator of statutory meaning to overcome the strict

statutory construction principle to which the language of § 6611 is subject. See Premo v. United

States, 599 F.3d 540, 547 (6th Cir. 2010) (“[I]n analyzing whether Congress has waived the

immunity of the United States, we must . . . not enlarge the waiver beyond what the language

requires” (internal quotation marks omitted)).

       Nor do we find any support for Ford’s position in subsequent legislative history. In 2004,

Congress enacted 26 U.S.C. § 6603, which provides that, contrary to previous practice, taxpayers

who deposit funds with the IRS and then request the return of those funds are entitled to interest in

                                                 -16-
Ford Motor Company v. United States
No. 10-1934

certain circumstances. Compare United States v. Domino Sugar Corp., 349 F.3d 84, 87 n.2 (2d Cir.

2003), with § 6603(d). Section 6603 provides for a different—and lower—interest rate for returned

deposits, when compared to the general overpayment interest rate applicable to overpayments under

§ 6611. Compare § 6603(d)(4), and § 6621(b), with § 6611(a), and § 6621(a)(1).

        Ford contends that since § 6603 allows a taxpayer who requests the return of his deposit to

recover interest from the remittance date, it makes little sense to interpret § 6611 to allow a taxpayer

who converts a deposit—rather than asking for its return—to recover interest only from the

conversion date. According to Ford, a taxpayer who requests the return of a deposit would then be

entitled to interest from an earlier date than the taxpayer who requests that a deposit be converted,

thus illogically rewarding the taxpayer who seeks the return of his deposit over the taxpayer who

actually converts his deposit into an advance payment of tax. The government responds that a

converted deposit is actually two sequential transactions—a constructive return of the deposit

followed by immediate re-submission of that deposit as a tax payment. Under this reasoning, § 6603

requires that the taxpayer be paid interest from the date of deposit to the date of return under the

lower § 6603(d)(4) interest rate, and be paid interest from the date of return (which is also the date

of resubmission) to the date of refund under the higher § 6621(a)(1) interest rate. In other words,

§ 6603 allows for the payment of interest at two different rates for a converted deposit, while prior

to the enactment of § 6603, interest would only be paid from the date of conversion forward.

        Although the government’s “constructive return” theory may be a flawed interpretation of

Revenue Procedure 84-58, it does make some sense when read in the context of § 6603, which only

deals with the accrual of interest on returned deposits. In any event, the passage of § 6603 does not

                                                 -17-

render the government’s interpretation of § 6611 illogical. Thus, subsequent legislative history,

which “generally deserves only limited weight,” does not alter our analysis here. See Buck v. Sec’y

of Health & Human Serv., 923 F.2d 1200, 1207 (6th Cir. 1991).

                                                 IV.

       Because the scope of Congress’s waiver of sovereign immunity in § 6611 is not “clearly

discernable from the statutory text in light of traditional interpretive tools” so as to allow Ford to

recover the overpayment interest it seeks here, see Cooper, 132 S. Ct. at 1448, we affirm the

judgment of the district court.
