OPINION

DUNCAN, Circuit Judge: 

Morton Sarubin filed personal income-tax returns in 1995 and 1996

showing a cumulative tax debt of nearly two million dollars, which

he never paid. After a decade of unsuccessful collection efforts, the

Internal Revenue Service ("IRS") sued to collect over four million

dollars, an amount representing the original debt and penalties plus

statutory interest. The government moved for summary judgment,

which the district court granted in part and denied in part. The court

allowed recovery on the original debt. However, the court held that

the government was estopped from collecting some two million dollars in interest that was not included in the indebtedness balance listed

in the Certificates of Assessment attached to the motion for summary

judgment. Because the government is statutorily entitled to recover

interest on unpaid taxes accruing to the date of payment, regardless

of whether such interest is reflected in an assessment, we reverse that

portion of the district court’s order.

I.

Sarubin timely filed his 1994 tax return, reporting taxable income

totaling $2,625,038 and a tax obligation of $1,136,877. He failed to

pay this amount. As a result, the IRS "assessed"1 a tax liability of

triggers levy and collection efforts." Hibbs v. Winn, 542 U.S. 88, 101

U.S.C. § 6322.

$1,136,877, a failure-to-pay penalty of approximately $11,000, and

interest on both in an amount nearing $16,000.2

History repeated itself in connection with Sarubin’s tax return for

1995. His October 17, 1996 filing3 reported taxable income totaling

$2,170,260 with $619,808 consequently due to the IRS. Again, he

failed to satisfy this obligation, and on November 18, 1996, the IRS

assessed against him a tax liability of $619,808, penalties of over

$58,000 and interest nearing $33,000.4

The IRS issued subsequent notices5 and demands for payment to

Sarubin, who nevertheless made only token payments towards his

obligations. The government ultimately filed a civil collection suit on

the debts in June 2005. The complaint alleged that the IRS had

assessed taxes, penalties, and interest in connection with Sarubin’s

1994 and 1995 tax returns, but that the assessed amounts had

remained unpaid. The complaint also noted that "[s]tatutory additions

for penalties and interest have accrued and will continue to accrue"

on the unpaid amounts. J.A. 4, 5. The government sought judgment

in the amount of $4,092,983, plus "statutory additions for interest"

accruing "after May 13, 2005, to the date of entry of judgment," and

continuing "until the judgment is fully paid." J.A. 5. 

The government soon moved for summary judgment, offering as

proof of the amount of Sarubin’s tax liability a "Certificate of Assessments, Payments and Other Specified Matters" (a "Certificate of

2The additional obligation to pay interest is intended to compensate the

government for the loss of use of its property during the time it takes for

the taxpayer to satisfy his arrears. United States v. Childs, 266 U.S. 304,

309-10 (1924). 

3Though returns for a given tax year are typically due the following

year on the 15th of April, §§ 6012, 6072, Sarubin obtained extensions of

time in which to file his 1995 return, see § 6072. 

4For each set of assessments, the amount of interest assessed represented the amount that had accrued since the April 15 standard return

due-date, regardless of when the return was actually filed. § 6601(b). 

5There is a factual dispute as to the precise content of the notices. The

exact amounts listed in the notices, however, are not relevant to our analysis here. 

UNITED STATES v. SARUBIN 3
Assessments" or "Certificate"), also known as a Form 4340, for each

of the 1994 and 1995 tax years. Generally, a Certificate of Assessments provides an itemized list of a given taxpayer’s assessed tax liability, as modified by subsequent assessments of debits and credits.

The Certificates here were prepared on September 2, 2005, and listed

the assessments of tax, interest, and penalties for 1994 and 1995 that

had been made on June 5, 1995, and November 18, 1996, respectively. The Certificates did not itemize any further assessments of

penalties or interest, but did record the occasional sending of notices

of indebtedness and the sporadic receipt of small payments. The final

page of each Certificate bears a line-item marked "balance," representing the sum of the itemized debits less any credits.6

Sarubin opposed the motion for summary judgment, raising, inter

alia, two objections relating to the Certificates. First, Sarubin argued

that the Certificates were insufficient as an evidentiary matter to substantiate the amount of damages the government sought to recover.

Second, Sarubin argued that the government should be limited to

recovering the "balances" listed on the Certificates, totaling

$1,867,376.70. 

The district court agreed on both counts, finding that the Certificates only supported recovery of the "balances" listed and that Sarubin would have been justified to read the "balances" as pay-off

amounts that would have fully satisfied the debt.7 It was "simply

6Each Certificate concludes with a signed certification statement. The

statements read, in full: 

I certify that the foregoing transcript of the taxpayer named

above in respect to the taxes specified is a true and complete

transcript for the period stated, and all assessments, abatements,

credits, refunds, and advance or unidentified payments, and the

assessed balance relating thereto, as disclosed by the records of

this office as of the account status date are shown therein. I further certify that the other specified matters set forth in this transcript appear in the official records of the Internal Revenue

Service. 

J.A. 19, 23. 

7We note that Sarubin never attempted to pay off the debts in reliance

on the Certificates’ alleged representation of a pay-off amount. 

4 UNITED STATES v. SARUBIN
untenable," the court held, for "the [g]overnment [to] send such a

notice representing a fixed figure as of a certain date and then seek

additional funds not previously stated." J.A. 35. The district court

therefore ordered payment of the underlying debts and the statutory

interest that accrued after the issuance of the Certificates. The district

court estopped the government, however, from collecting the unitemized and unassessed statutory interest—over $1.5 million in connection with the 1994 tax year that had accrued from April 15, 1995 to

September 2, 2005, and over $700,000 in connection with the 1995

tax year that had accrued from April 15, 1996 to September 2, 2005.

The government now appeals, seeking reversal of the district court

only with respect to its denial of recovery of full interest on the debts.

II.

We review de novo the district court’s partial denial of the government’s motion for summary judgment. Shaw v. Stroud, 13 F.3d 791,

798 (4th Cir. 1994). Such a motion should be granted when "‘there

is no genuine issue as to material fact’" and the government "‘is entitled to judgment as a matter of law.’" Id. (quoting Fed. R. Civ. P.

56(c)). 

Like the imposition of tax obligations themselves, the accrual of

interest on tax obligations is governed by the Internal Revenue Code

(the "Code"). "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." 26

U.S.C. § 6601(a) (emphasis added).8 Because accrued interest is

treated under the Code in the same manner as the underlying tax obligation, § 6601(e)(1), the "amount of tax" that accrues further interest

under § 6601(a) includes interest already accrued. See United States

8Other sections of the Code unpack the statutory terms used in

§ 6601(a). For taxpayers like Sarubin, the "last date prescribed for payment" falls on April 15 of the calendar year following the underlying tax

year. See §§ 6072, 6151, 6601(b). The "underpayment rate" is a percentage set by the Secretary of the IRS on a quarterly basis, § 6621, though

the interest itself compounds daily, § 6622. 

UNITED STATES v. SARUBIN 5
v. Banks, 442 F.2d 43, 45 (8th Cir. 1971).9

 Reading these Code provisions in conjunction, we find § 6601(a) to plainly require a dilatory

taxpayer to pay interest accruing from the date the tax is due and

compounding until the date the total obligation is paid. 

When a taxpayer fails to satisfy an obligation, the government may

proceed in two ways. First, it may opt to institute summary collection

procedures. The ability to pursue such procedures springs from the

government’s power to attach a federal tax lien on all property of a

delinquent taxpayer. § 6321. Before the government can exercise such

power, it must first provide notice of its intent to do so, § 6303(a), for

the protection of the taxpayer. United States v. Berman, 825 F.2d

1053, 1059-60 (6th Cir. 1987). Then, the government must make an

assessment, which gives rise to a lien in "the amount so assessed."

§ 6322.10 Independent of these administrative actions, however, interest continues to accrue automatically on any unpaid debt. § 6601(a).

Alternatively, the government may seek to collect unpaid obligations via its common-law right to sue on a debt. Milwaukee County

v. M.E. White Co., 296 U.S. 268, 271 (1926). In contrast to the notice

requirement in summary collection procedures, the government is not

required in a common-law action to issue additional notice of its

intent to recover the debt beyond the filing of the complaint. United

States v. Jersey Shore State Bank, 781 F.2d 974, 979-80 (3d Cir.

1986) (holding that when "the government cannot proceed administratively" and instead institutes a civil action, "service of the government’s complaint provides the party with all the notice and protection

required"). Likewise, an administrative assessment of the full obligation, a necessary step in summary collection procedures, is not a prerequisite to collection via common-law suit. In re Davis, 936 F.2d

771, 774 (4th Cir. 1991). Indeed, a contrary rule would raise practical

9That is, the taxpayer is liable not only for interest on the initial tax

obligation, but for interest on that interest as well. 

10Such an assessment is merely the administrative recording of an

existing liability. See § 6203; Hibbs, 542 U.S. at 101 (defining the term

"assessment" to mean "the official recording of liability that triggers levy

and collection efforts"); Cohen v. Mayer, 199 F. Supp. 331, 332 (D.N.J.

1961) ("The purpose of an assessment is to place the taxes owed on the

books of the Government."). 

6 UNITED STATES v. SARUBIN
difficulties. Since interest compounds daily, § 6622, the government

would have to calculate and assess the ever-compounding interest

anew each day that its common-law action remained unresolved and

the debt unpaid. 

The proceedings here are the result of a common-law collection

action, not a summary collection effort. Under In re Davis, then, the

government was required to do nothing more than file suit to initiate

collection of Sarubin’s full obligation—including taxes, penalties, and

interest accruing from the date the taxes were due by operation of law

under § 6601(a). See 936 F.2d at 774. We therefore reject Sarubin’s

argument on appeal that the government can only recover the

assessed debts in this common-law collection action.11

Notwithstanding the straightforward analysis reflected in our precedent, the district court found that the Certificates represented a collective "balance" owed of only $1,867,376.70, and that Sarubin could

justifiably rely on that balance as a pay-off amount. Invoking principles of estoppel, the district court apparently concluded that Sarubin

reasonably relied on the assessed balance to his detriment. The court’s

concern was misplaced for two reasons. 

First, the holding below misconstrues the role that Certificates of

Assessment play in collection proceedings. Certificates of Assessment

serve a limited evidentiary purpose; they are commonly used to prove

the amount of the underlying tax liability. Because the IRS’s determination that a tax is owed is presumed correct, United States v. Hardy,

299 F.2d 600, 606 (4th Cir. 1962), the government can "establish[ ]

a prima facie case in support of the tax liability charged in the complaints when it introduce[s] into evidence the certified copies of the

11To the extent that Sarubin complains of a lack of notice of the

amount he now owes, he cannot maintain that he is unfairly surprised.

Section 6601(a) mandates the accrual of such interest, and the government’s complaint facially demanded over two million dollars of

"[s]tatutory . . . interest [that] ha[d] accrued and will continue to accrue,"

J.A. 4, 5 (emphasis added). Sarubin may be surprised as a matter of

mathematics that the interest he owes now exceeds the amount of the

underlying obligation, but he can hardly contend that he is surprised as

a matter of inadequate notice. 

UNITED STATES v. SARUBIN 7
certificates of assessment," United States v. Pomponio, 635 F.2d 293,

296 (4th Cir. 1980). Although establishing the amount of tax liability

is a matter of evidence, the amount of interest accrued on such tax liability is a matter of law. United States v. Schroeder, 900 F.2d 1144,

1150 n.5 (7th Cir. 1990). Therefore, the government provided sufficient evidence to prove that Sarubin owed the underlying tax debt

sought, which debt has in turn accrued interest by operation of statute.

The district court’s suggestion that the government failed to show a

prima facie case by attaching the Certificates and citing to § 6601(a)

was thus inaccurate. 

Second, Sarubin has no legitimate claim to the equitable principles

of estoppel. The mere attachment of the Certificates of Assessment to

the government’s motion for summary judgment could not justify

reliance on the "balance" listed as a pay-off amount. We find a comparison to a remarkably similar case decided by the Court of Federal

Claims to be instructive. See Ghandour v. United States, 37 Fed. Cl.

121, 127 (1997), aff’d, 132 F.3d 52 (Fed. Cir. 1997) (unpublished

table opinion). In Ghandour, a taxpayer likewise argued that the government’s recovery of outstanding debts should be limited to the

amounts expressly itemized in a Certificate of Assessment. The Certificate in question certified that it included "all assessments, penalties, interests, abatements, credits, refunds, and advance or

unidentified payments relating thereto." Id. at 126 (emphasis added).

The court nevertheless held that the Certificate "cannot alter the

amount of interest" which the government "is entitled to recover . . .

because interest accrues . . . by operation of law," id. at 127 (internal

quotations omitted). 

Sarubin is an even less-likely candidate for the relief of estoppel

than was the taxpayer in Ghandour. The Certificates here are, by their

own terms, certified transcripts only of "assessments, abatements,

credits, refunds, and advance or unidentified payments, and the

assessed balance relating thereto." J.A. 19, 23 (emphasis added).

Sarubin could not justifiably rely on the Certificates to include unassessed interest when the Certificates do not include unassessed debts

of any kind. Furthermore, and in contrast to the certification in Ghandour, the Certificates here do not purport to include "interest" at all.

In any event, it is unclear how Sarubin might have relied on the bal8 UNITED STATES v. SARUBIN
ances since the Certificates were not presented to him until the motion

for summary judgment was filed. 

The Code leaves no room for a taxpayer to evade his responsibility

to pay the taxes he owes. When a taxpayer, for whatever reason, does

not meet his obligation in a timely manner, the debt automatically

begins accruing interest by operation of statute. Sarubin’s case presents no exception. The government adequately proved Sarubin’s liability for the underlying taxes, and Sarubin is thus obligated to pay

his tax burden along with the interest that it has accrued in the twelve

years since he first failed to pay.

III.

Because we find that there is no issue of material fact and that the

government is entitled to judgment as a matter of law, we vacate and

remand with instructions for the district court to enter judgment in

favor of the government for the full amount sought, including the

interest that started accruing in 1995 and the interest that continues to

accrue until the obligation is fully satisfied.
