This is an appeal from a conviction for two counts of income tax evasion in violation of 26 U.S.C. § 7201.
Evidence presented at trial showed that from 1964 to 1970 appellant Hiett’s chief source of income was a divorce consulting firm. During this time appellant routinely paid his bills by check. The divorce consulting firm closed in late 1970 or early 1971. At about that time appellant began paying for everything in cash, including such large purchases as a house and an airplane. He filed no individual tax returns for 1971 or 1972. This led the government to investigate his tax liabilities for those years.
In its investigation the government used the net wоrth method of reconstructing income. Under that method the IRS showed substantial increases in appellant’s net worth for the years in question and found that appellant had taxable income of $16,-000 in 1971 and $28,000 in 1972. Appellant did not cooperate in the investigation, nor did he offer any explanation for his increased net worth. The jury found him guilty of income tax evasion for the years of 1971 and 1972. He appeals.
I.
The principal issue„raised on appeal concerns the government’s burden of proof in a criminal prosecution for income tax evasion. To establish a § 7201 violation, the government must prove (1) the existence of a tax deficiency, (2) an affirmative act constituting an evasion or attempted evasion of the tax due, and (3) willfulness.
Sansone v. United States,
To establish a tax deficiency, the government must show first that the taxpayer had unreported income, and second, that the income was taxable. Thе government has several customary ways of overcoming the first hurdle. Here it used the net worth O method of reconstructing income. 1 Appel *1201 lant does not contest the government’s calculations under that method.
The government, however, does not satisfy its burden of proving a tax deficiency simply by showing that the taxpayer had unreported incomе for the year in question. In addition, the government must prove that the unreported income was
taxable
income. This is the aspect of the government’s case which appellant contests. Under the Supreme Court’s decisions, the government can satisfy this burden in either of two ways. It can show that there is a likely taxable source of the unreported income,
Holland v. United States,
It is impossible, of course, to negate every
possible
nontaxable source. In the typical case, the taxpayer gives the IRS “leads” to possible nontaxable sources. Some cases have held that the government satisfies its burden if it negates each of these leаds.
E. g., Kramer v. Commissioner of Internal Revenue,
To adopt appellant’s position would require the government to exhaust the inex-haustable — to conduct an absolutely limitless investigation. It would cast the government in the role of a conjurer, forcing it to pull nontaxable sources out of a hat. Appellant would require the government to embark on a Magellan-like expedition in order to prove that the unreported income was taxable. Not only would the government have to circle the globe in its search, it would also have extraorbital responsibility, since appellant’s position requires it to prove a cosmic negativе. To state appellant’s position is to establish its absurdity. If Massei and Holland are to have viability in our jurisprudence, they cannot be read to sanction such a result.
Our cases adequately rebut appellant’s position. In
United States v. Boulet,
For purposes of this standard, a thorough investigation must be, of course, one which removes any reasonable doubt that the defendant’s unreported income came from nontaxable sources. In this case the government made such an investigation. It contacted banks and third parties — including appellant’s family — in an attempt to find out if appellant received any income by gift, loan, inheritance, or other nontaxable source. The gоvernment located no nontaxable sources that could account for appellant’s unreported income. As we explained in Penosi,
the government cannot be expected to conduct an exhaustive nationwide investigation when the defendant supplies no relevant leads . . . thе government agent did enough to carry the burden of proof when he interviewed friends and relatives and checked with financial and government institutions at both the present and former residences of the defendant.
United States v. Penosi,
We wish to emphasize that our holding in no way shifts the burden of proof to the defendant. He is nоt required to supply leads or testify in court. The burden of establishing a taxable source remains on the government throughout the trial. But, as we stated in
Penosi,
once “the results of the investigation were put into evidence, the government established a
prima facie
case, and by remaining silent, [the defendant] took the risk that the jury wоuld believe the government’s witnesses and find him guilty.”
Id.
After the government establishes its
prima facie
case, the taxpayer defendant — like all other defendants — “remains quiet at his peril.”
Holland v. United States,
II.
Appellant raises another issue on appeal related to the government’s burden of proof. He contends that the district court erroneously placed the burden of proof on him to show that his expenditures were for business and not personal purposes. In other words appellant argues that the government, to carry its burden of proof in a prosecution for income tax evasion, must prove that the defendant has no unclaimed deductions.
Wе hold that the district court correctly placed the burden of proving deductions on appellant. The law in this area is clear. In a prosecution for income tax evasion, once the government has established the defendant’s unreported income and has allowed both the deductions that the defendant claims and those that it can calculate without the defendant’s assistance, it is not then required to prove that the defendant has no other deductions. The burden of proving additional deductions is on the defendant.
United States v. Garguilo,
III.
The third issue raised on appeal is whether the trial court сorrectly admitted into evidence certain testimony of an IRS agent who investigated the appellant. The disputed colloquy between the prosecutor and the agent is as follows:
Q: During the course of your investigation, how did you proceed? What did you do?
*1203 A: We attempted to interview Mr. Hiett and—
Q: And did you meet with Mr. Hiett and Mr. Leeper [appellant’s attorney] at that time?
A: Yes, we did.
Q: Did you inform Mr. Leeper and Mr. Hiett that you were investigating tax liabilities of Mr. Hiett?
A: Yes.
Q: All right. After informing him of the investigation, what, if anything, happened? Did Mr. Leeper continue the interrogation at that time or the conference at that time?
A: No, sir, the interview was terminated at that point.
Q: All right. Did you have occasion during your investigation thereafter to ever meet again with Mr. Leeper or Mr. Hiett?
A: No, I did not.
Appellant argues that under
United States v. Hale,
We cannot hail the
Hale
case into the
Hiett
trial.
Hale
does not control this case. The testimony thе appellant complains of was not nearly as prejudicial as was the testimony at issue in
Hale.
Here, the disputed testimony was not even a clear comment on the appellant’s exercise of his right to remain silent. The witness merely stated that the interview was terminated and the parties nevеr met again. It certainly does not have the prejudicial impact of testimony-such as that in
Hale
— indicating that an accused remained silent in the face of police interrogation at the time of arrest. See
United States v. Griffin,
Furthermore, the testimony in this case has greater probative value than the testimоny challenged in
Hale.
In
Hale
the defendant’s pre-trial silence was only probative on the issue of his credibility. And, as we have said, “doubt should not be cast upon [a defendant’s] . . . credibility as a penalty for exercising his prerogative to make no statement to the arresting officer.”
United States v. Impson,
*1204 IV.
Appellant’s final contention on appeal is that a portion of the prosecutor’s closing argument constitutes reversible error. The challenged statements are those in which the prosecutor seems to vouch for the two IRS agent witnesses. 3
As appellant contends, the trial court may commit reversible error by allowing a prosecutor to vouch for his witnesses in closing argument.
E. g., United States v. Arteaga-Limones,
Even if the prosecutor’s remarks did not fall within the fair reply doctrine, we would not be convinced that they constitute reversible error. The thrust of the prosecutor’s remarks was that the IRS agents did a commendable job. This, by any reasonable interpretation, would mean that they conducted a thorough investigation of appellant’s fiscal affairs. Evidence of this was in the record, and whether the agents did a good or bad job was a proper subject for argument. We therefore hold that the challenged portions of the prosecutor’s closing argument were not improper.
For these reasons the judgment of the district court is affirmed.
AFFIRMED.
Notes
. To establish unreported income under the net worth method, the government must establish the taxpayer’s net worth at the beginning of the tax year in question. Then the government must establish the taxpаyer’s net worth at the close of that year. It subtracts the former figure from the latter to show the taxpayer’s increase in net worth for the year in question. This figure is further adjusted by (1) adding to it the taxpayer’s nondeductible personal expenditures for the year and (2) subtracting from it the taxpayer’s allowablе deductions. If, as in appellant’s case, the taxpayer filed no
*1201
return for the year in question, this “adjusted net worth increase” is presumed to be the taxpayer’s unreported income for that year.
See Holland v. United States,
. In both cases the government established that the taxpayer’s opening net worth was too small to account for his expenditures or bank deposits. This justified the conclusion that the taxpayer had unreported income.
. The prosecutor said, “I am proud of these fellows that work long, hard hours for these United States. They try their dead level best to see that the proper taxes are collected, because 1 think its important that this Nation have a good defense . . [they] have done a commendable job.”
