delivered the opinion of the Court.
Chapter 75, subchapter A, of the Internal Revenue Code of 1954, as amended, 26 U. S. C. §§ 7201-7241, is concerned with tax crimes. Sections 7201-7207, inclusive, which in the aggregate relate to attempts to evade or defeat tax, to failures to act, and to fraud, all include the word “willfully” in their respective contexts. Specifically, § 7206 is a felony statute and reads:
“§ 7206. Fraud and false statements.
“Any person who—
“(1) Declaration under penalties of perjury. “Willfully makes and subscribes any return, statement, or other document, which contains or is verified by a written declaration that it is made under the penalties of perjury, and which he does not believe to be true and correct as to every material matter ....
“shall be guilty of a felony and, upon conviction thereof, shall be fined not more than $5,000, or imprisoned not more than 3 years, or both, together with the costs of prosecution.”
Section 7207 is a misdemeanor statute 1 and reads:
“7207. Fraudulent returns, statements, or other documents.
*348 “Any person who willfully delivers or discloses to the Secretary or his delegate any list, return, account, statement, or other document, known by him to be fraudulent or to be false as to any material matter, shall be fined not more than $1,000, or imprisoned not more than 1 year, or both.”
This case presents the issue of the meaning of the critical word “willfully” as it is employed in these two successive statutes. Is its meaning the same in each, or is the willfulness specified by the misdemeanor statute, § 7207, of somewhat less degree than the felony willfulness specified by § 7206?

Respondent, Cecil J. Bishop, was convicted by a jury on all three counts of an indictment charging him with felony violations of § 7206 (1) with respect to his federal income tax returns for the calendar years 1963, 1964, and 1965. The Court of Appeals, holding that a lesser-included-offense instruction directed to the misdemeanor statute, § 7207, was improperly refused by the trial judge, reversed the judgment of the District Court and remanded the case for a new trial.
*349 We conclude that it was proper and correct for the District Court to refuse the lesser-included-offense instruction. In our view, the word “willfully” has the same meaning in both statutes. Consequently, we reverse and remand so that the Court of Appeals may now proceed to consider the additional issues that court found it unnecessary to reach.
II
Mr. Bishop is a lawyer who has practiced his profession in Sacramento, California, since 1951. During that period, he owned an interest in a walnut ranch he and his father operated. In 1960 his secretary, Louise, married his father. The father died, and thereafter respondent’s stepmother managed the ranch.
Respondent periodically sent checks to Louise. These were used to run the ranch, to pay principal on loans, and to make improvements.
Louise maintained a record of ranch expenditures and submitted an itemized list of these disbursements to respondent at the end of each calendar year. In his 1963 return respondent asserted as business deductions all amounts paid to Louise and, in addition, all the expenses Louise listed. This necessarily resulted in a double deduction for all ranch expenditures in 1963. Moreover, some of these expenditures were for repayment of loans and for other personal items that did not qualify as income tax deductions. In his 1964 and 1965 returns respondent similarly included nondeductible amounts among the ranch figures that were deducted.
The aggregate amount of improper deductions taken by respondent for the three taxable years exceeded *350 $45,000. He enjoyed aggregate gross income for those years of about $70,000.
The incorrectness of the returns as filed for the three years was not disputed at trial. Transcript of Trial 869-872, 1148. Neither is it disputed here. Brief for Respondent 4.
Ill
Section 7206 (1), the felony statute, is violated when one “[wjillfully makes and subscribes any return,” under penalties of perjury, “which he does not believe to be true and correct as to every material matter.” Respondent based his defense at trial on the ground that he was not aware of the double deductions asserted in 1963 or of the improper deductions taken in the three taxable years. He claimed that his law office secretary prepared the return schedules from his records and from the information furnished by Louise; he merely failed to check the returns for accuracy.
Respondent requested lesser-included-offense instructions based on the misdemeanor statute, § 7207. This tax misdemeanor is committed by one “who willfully delivers or discloses” to the Internal Revenue Service any return or document “known by him to be fraudulent or to be false as to any material matter.” Respondent argued that the word “willfully” in the misdemeanor statute should be construed to require less scienter than the same word in the felony statute. App. 28. With the state of respondent's guilty knowledge in dispute, his proposed instructions would have allowed the jury to choose between a misdemeanor based on caprice or careless disregard and a felony requiring evil purpose. The trial judge declined to give the requested instructions and, instead, gave an instruction only on the felony, requiring a finding by the jury that the defendant intended *351 “with evil motive or bad purpose either to disobey or to disregard the law.” App. 24.
After the guilty verdict on all counts was returned, respondent was sentenced to two years’ imprisonment on each count, the sentences to run concurrently. The court, however, suspended all but 90 days of each sentence and placed respondent on probation for five years on condition that he pay a fine of $5,000. App. 31.
IV
The Court of Appeals relied upon and followed,
A. The Ninth Circuit rule appears to have been evolved from language in this Court’s opinion in
Spies
v.
United States,
“The difference between willful failure to pay a tax when due, which is made a misdemeanor, and willful attempt to defeat and evade one, which is made a felony, is not easy to detect or define. Both must be willful, and willful, as we have said, is a word of many meanings, its construction often being influenced by its context. United States v. Mur-dock,290 U. S. 389 . It may well mean something more as applied to nonpayment of a tax than when applied to failure to make a return. Mere voluntary and purposeful, as distinguished from accidental, omission to make a timely return might meet the test of willfulness. But in view of our traditional aversion to imprisonment for debt, we would not without the clearest manifestation of Congressional intent assume that mere knowing and intentional default in payment of a tax, where there had been no willful failure to disclose the liability, is intended to constitute a criminal offense of any degree. We would expect willfulness in such a case to include some element of evil motive and want of justification in view of all the financial circumstances of the taxpayer.
“Had § 145 (a) not included willful failure to pay a tax, it would have defined as misdemeanors gen *353 erally a failure to observe statutory duties to make timely returns, keep records, or supply information— duties imposed to facilitate administration of the Act even if, because of insufficient net income, there were no duty to pay a tax. It would then be a permissible and perhaps an appropriate construction of § 145 (b) that it made felonies of the same willful omissions when there was the added element of duty to pay a tax. The definition of such nonpayment as a misdemeanor, we think, argues strongly against such an interpretation.”317 U. S., at 497-498 .
In
Abdul
the court considered an appeal by a taxpayer convicted of tax misdemeanors (§ 2707 (b) of the 1939 Code and § 7203 of the 1954 Code) based on failure to file but acquitted of tax felonies (§ 2707 (c) of the 1939 Code and § 7202 of the 1954 Code) based on failure to account for and pay withholding taxes. The defense was inability to pay. The trial judge instructed the jury that the term “wilful” in the misdemeanor counts meant, among other things, “capriciously or with a careless disregard whether one has the right so to act,” whereas the same word in the felony counts meant “with knowledge of one’s obligation to pay the taxes due and with intent to defraud the Government of that tax by any affirmative conduct.”
“the word ‘wilful’ as used in the misdemeanor statute means something less when applied to a failure to make a return than as applied to a felony non-payment of a tax. This being true, then the words used in the instruction defining ‘wilful’ as relates to a misdemeanor adequately and clearly point up that difference.” Ibid.
*354
Because of an error in the cross-examination of Abdul, his conviction was reversed. On retrial, he was again convicted. He appealed, and the judgment was affirmed.
Abdul
v.
United States,
In the present case the Court of Appeals continued this
Abdul
distinction between willfulness in tax misdemeanor charges and willfulness in tax felony charges. Section 7207, it was said, requires only a showing of “unreasonable, capricious, or careless disregard for the truth or falsity of income tax returns filed,” whereas § 7206 (1) “requires proof of an evil motive and bad faith.”
B. The decisions of this Court do not support the holding in
Abdul,
and implicitly they reject the approach taken by the Court of Appeals. In
Spies,
the Court speculated,
In
Berra
v.
United States,
Although the misdemeanor statute, §3616 (a), proffered by the defendant in
Berra
did not contain the word “willfully,” the
Berra
facts were presented to the Court again in
Sansone
v.
United States,
“Given petitioner's material misstatement which resulted in a tax deficiency, if, as the jury obviously found, petitioner's act was willful in the sense that he knew that he should have reported more income than he did for the year 1957, he was guilty of violating both §§ 7201 and 7207. If his action was not willful, he was guilty of violating neither.”380 U. S., at 353 .
The same analysis v/as applied to the requested lesser-included-offense instruction for § 7203. Id., at 352. The clear implication of the decision in Sansone is that the word “willfully” possesses the same meaning in §§ 7201, 7203, and 7207. Sansone thus foreclosed the argument that the word “willfully” was to be given one meaning in the tax felony statutes and another meaning in the tax misdemeanor statutes.
The thesis relied upon by the Court of Appeals, therefore, was incorrect.
y
It would be possible, of course, that the word “willfully” was intended by Congress to have a meaning in § 7206 (1) different from its meaning in § 7207, and we turn now to that possibility.
We continue to recognize that context is important in the quest for the word’s meaning. See
United States
v.
Murdock,
A. Respondent argues that both §§ 7206 (1) and 7207 apply to a fraudulent “return” and cover the same ground if the word “willfully” has the same meaning in both sections. Since “it would be unusual and we would not readily assume that Congress by the felony . . . meant no more than the same derelictions it had just defined ... as a misdemeanor,”
The critical difficulty for respondent is that the two sections have substantially different express terms. The most obvious difference is that § 7206 (1) applies only if the document “contains or is verified by a written declaration that it is made under the penalties of perjury.” No equivalent requirement is present in § 7207. Respondent recognizes this but then relies on the presence of perjury declarations on all federal income tax returns, a fact that effectively equalizes the sections where a federal tax return is at issue. See 26 U. S. C. § 6065 (a). 7
This approach, however, is not persuasive for two reasons. First, the Secretary or his delegate has the power under § 6065 (a) to provide that no perjury declaration is required. If he does so provide, then § 7207 *358 immediately becomes operative in the area theretofore covered by § 7206 (1). Second, the term “return” is not necessarily limited to a federal income tax return. A state or other nonfederal return could be intended and might not contain a perjury warning. If this type of return were submitted in support of a federal return, or in the course of a tax audit, § 7207 could apply even if § 7206 (1) could not.
There are other distinctions. The felony applies to a document that a taxpayer “[w]illfully makes and subscribes . . . and which he does not believe to be true and correct as to every material matter,” whereas the misdemeanor applies to a document that a taxpayer “willfully delivers or discloses to the Secretary or his delegate . . . known by him ... to be false as to any material matter.” In the felony, then, the taxpayer must verify the return or document in writing, and he is liable if he does not affirmatively believe that the material statements are true. For the misdemeanor, however, a document prepared by another could give rise to liability on the part of the taxpayer if he delivered or disclosed it to the Service; additional protection is given to the taxpayer in this situation because the document must be known by him to be fraudulent or to be false.
These differences in the respective applications of §§ 7206 (1) and 7207 provide solid evidence that Congress distinguished the statutes in ways that do not turn on the meaning of the word “willfully.” Judge Hastie, in analyzing this Court's holding in Spies, appropriately described this distinction as follows:
“However, this distinction is found in the additional misconduct which is essential to the violation of the felony statute . . . and not in the quality *359 of willfulness which characterizes the wrongdoing.” United States v. Vitiello,363 F. 2d 240 , 243 (CA3 1966).
Thus the word “willfully” may have a uniform meaning in the several statutes without rendering any one of them surplusage. We next turn to context.
B. The hierarchy of tax offenses set forth in §§ 7201-7207, inclusive, utilizes the mental state of the offender as a guide in establishing the penalty. Section 7201, relating to attempts to evade or defeat tax, has been described and recognized by the Court as the “climax of this variety of sanctions” and as the “capstone of a system of sanctions which singly or in combination were calculated to induce prompt and forthright fulfillment of every duty under the income tax law and to provide a penalty suitable to every degree of delinquency.”
Spies,
All these offenses, except two subsections of § 7206, viz., subsections (3) and (4), require that acts be done “willfully.” Although the described states of mind might be included in the normal meaning of the word “willfully,” the presence of both an express designation and the simultaneous requirement that a violation be committed “willfully” is strong evidence that Congress used *360 the word “willfully” to describe a constant rather than a variable in the tax penalty formula. 8
The Court, in fact, has recognized that the word “willfully” in these statutes generally connotes a voluntary, intentional violation of a known legal duty. It has formulated the requirement of willfulness as “bad faith or evil intent,”
Murdock,
This longstanding interpretation of the purpose of the recurring word “willfully” promotes coherence in the group of tax crimes. In our complex tax system, uncertainty often arises even among taxpayers who earnestly wish to follow the law. The Court has said, “It is not the purpose of the law to penalize frank difference of opinion or innocent errors made despite the
*361
exercise of reasonable care.”
Spies,
Until Congress speaks otherwise, we therefore shall continue to require, in both tax felonies and tax misdemeanors that must be done “willfully,” the bad purpose or evil motive described in Murdock, supra. We hold, consequently, that the word “willfully” has the same meaning in § 7207 that it has in § 7206 (1). Since the only issue in dispute in this case centered on willfulness, it follows that a conviction of the misdemeanor would clearly support a conviction for the felony. 9 Under these circumstances a lesser-included-offense instruction was not required or proper, for in the federal system it is not the function of the jury to set the penalty. Berra v. United States, 351 U. S., at 134r-135.
*362 The judgment of the Court of Appeals is reversed, and the case is remanded for further proceedings.
It is so ordered.
Mr. Justice Douglas would affirm the judgment of the Court of Appeals for the Ninth Circuit on the opinion written for that court by Judge Powell.
Notes
Title 18 U. S. C. § 1 defines felony and misdemeanor:
“§ 1. Offenses classified.
“Notwithstanding any Act of Congress to the contrary:
“(1) Any offense punishable by death or imprisonment for a term exceeding one year is a felony.
“(2) Any other offense is a misdemeanor.”
Compare
United States
v.
Vitiello,
United States
v.
Haseltine,
One possible result of this distinction, of course, is that the Government’s burden in a misdemeanor case could be less than in a felony case.
The applicability of § 3616 (a) of the 1939 Code to income tax returns was not contested in
Berra
v.
United States,
See H. R. Rep. No. 1337, 83d Cong., 2d Sess., A425 (1954); S. Rep. No. 1622, 83d Cong., 2d Sess., 602-603 (1954). The prede
*357
cessor to § 7206 (1) was § 3809 (a) of the 1939 Code. The antecedent to § 7207 was, as we have noted above, § 3616 (a) of the 1939 Code. See
Scmsone,
“§ 6065. Verification of returns.
"(a) Penalties of perjury.
“Except as otherwise provided by the Secretary or his delegate, any return, declaration, statement, or other document required to be made under any provision of the internal revenue laws or regulations shall contain or be verified by a written declaration that it is made under the penalties of perjury.” See also Treas. Reg. § 1.6065-1 (1972).
Semantic confusion sometimes has been created when courts discuss the express requirement of an “attempt to evade” in § 7201 as if it were implicit in the word “willfully” in that statute. This type of analysis produces language suggesting that “willfully” in § 7201 has a different meaning from the same term in § 7203. See
United States
v.
Ming,
The Government has argued that the misdemeanor of § 7207 could never be a lesser included offense in § 7206 (1) because the misdemeanor requires that the actor have knowledge of the falsity. This is said to create an additional element in the misdemeanor, not present in the felony, so the misdemeanor is not “necessarily included” in the felony, within the meaning of Fed. Rule Crim. Proc. 31 (c). Our conclusion that the word "willfully” has the same meaning in both statutes makes it unnecessary to reach this contention.
