OPINION
RABINOWITZ, Chief Justice.
These appeals involve the refusal by individual taxpayers, on the basis of constitutional privilege, to provide any information on their state income tax returns regarding [1158]*1158the amount or source of income, and then subsequently refusing to comply with an administrative summons issued under AS 43.05.040, ordering them to appear and testify regarding their tax liability and to produce records pertinent to determining their tax liability. Pickles “gifted” the state $203 in lieu of paying taxes. The records demanded of the Olivers (husband and wife) were W-2 forms received from employers “or pay records”, bank statements, credit union statements, and copies of their federal tax returns for various years. The summons directed to Pickles was worded more broadly, directing him to produce
all books, records, and papers necessary to determine the correct Alaska Individual Net Income Tax Liability for the year 1977. This may include but is not limited to the following: cash receipts and disbursement records, checking and saving account records, stock and real estate records, all W-2 forms or pay records from all employer's[,] workpapers, ledgers, journals, etc.
Pickles and the Olivers appeared in response to these summonses. The state apparently did not seek testimony from the Olivers, but the Olivers refused to produce any of the documents sought. Pickles eventually appeared twice before the tax auditor but brought none of the documents requested and refused to answer questions on the tax return on the basis of “the First, Fourth, Fifth, Seventh, Eighth, Ninth, Tenth and Fourteenth” amendments.
Pickles and Stephen Oliver were jailed for civil contempt after appearances before the superior court to show cause for not complying with the summonses. Both have since been released: Oliver after the superi- or court granted a motion for reconsideration and decided the Olivers were entitled to refuse to comply with the summons based on Fifth Amendment grounds, and Pickles after this court stayed the contempt order against him pending appeal.
The state is the appellant in No. 4755 and the appellee in No. 5049. Pickles and the Olivers are appearing pro se against the state in these appeals. The Olivers have relied on the Fifth Amendment to the U.S. Constitution, its counterpart in the Alaska Constitution, and the right to privacy in the Alaska Constitution to support their position. Pickles, in addition to relying on the authorities cited by the Olivers, cites the Fourth Amendment and its state counterpart and the language of AS 43.05.040. He disputes the propriety of holding him in contempt for his actions, and asserts other deficiencies.
We reverse the ruling of the superior court in each case.
Before turning to the major legal issues presented in these appeals we will initially address several minor issues which have been raised.
I. Whether AS 43.05.040(a)1 authorizes the summons which was issued by the Department of Revenue in Pickles’s case.
Pickles argues that AS 43.05.040(a) does not support the summons issued here. [1159]*1159Pickles contends that the only books and papers AS 43.05.040(a) opened to inspection by the Department of Revenue are certain business records, and those only at reasonable times. In our view Pickles has misread the statute and thus his argument is without merit.
II. Whether the Department of Revenue’s failure to affix the seal of the Commissioner of Revenue to the summons which was issued in Pickles’s case precludes its enforcement.
AS 43.05.010(6) states that the Commissioner of Revenue shall “adopt a seal and affix it to each order, process, or certificate issued by him.” The state did not affix such a seal to the summons which was issued to Pickles, but this defect was brought to the attention of the superior court, which apparently concluded that since there was no doubt as to the authenticity of the summons, this error was harmless. Since Pickles appeared in response to the summons and has otherwise treated it as authentic, we conclude that this technical defect was harmless error.
III. Whether the superior court was authorized to order Pickles incarcerated for civil contempt for refusing to comply with the summons.
Pickles’s primary contention is that he cannot be jailed for contempt because his actions were in good faith and not willful. We find this argument non-meritorious. Bad faith is not a prerequisite to a finding of civil contempt, which is intended not to punish the contemnor for having flouted the court’s authority, but to coerce future conduct. See L.A.M. v. State, 547 P.2d 827, 832 (Alaska 1976). Willfulness is a prerequisite, but only in the sense that the act ordered must be within the power of the defendant to perform.2 We have held that inability to comply is an affirmative defense to a contempt charge, with the burden of proof on the defendant. Johansen v. State, 491 P.2d 759, 766 (Alaska 1971). Here, Pickles raised no issue and presented no evidence that he was unable to comply, beyond asserting that some of his refusals were based partially on his confusion as to what was meant by certain monetary terms.
IV.Whether constitutional rights against self-incrimination, under the federal or Alaska Constitution, protect Pickles and the Olivers from testifying or producing the documents requested by the administrative summonses.
A. Failure to file a return.
The state characterizes the taxpayers’ stance as an assertion that they have a right to refuse to comply with the requirement that they fill out a tax return.3 It is [1160]*1160well established that no such right exists under the Fifth Amendment or other provisions of the U.S. Constitution. The privilege against self-incrimination does not extend to a right to refuse to file any return at all. United States v. Sullivan, 274 U.S. 259, 263, 47 S.Ct. 607, 71 L.Ed. 1037, 1039 (1927). A blanket refusal to disclose any financial information on the return on the basis of the Fifth Amendment is equivalent to filing no return at all.4
California v. Byers, 402 U.S. 424, 91 S.Ct. 1535, 29 L.Ed.2d 9 (1971), which dealt with a California statute requiring the drivers of vehicles involved in an accident to stop at the scene and give their names and addresses, established that a balancing between legitimate government functions and the interests of the individual is required in situations where self-reporting is a part of a regulatory scheme. Id. at 427, 91 S.Ct. at 1537, 29 L.Ed.2d at 17. This entails “an evaluation of the assertedly noncriminal governmental purpose in securing the information, the necessity for self-reporting as a means of securing the information, and the nature of the disclosures required.” Id. at 454, 91 S.Ct. at 1551, 29 L.Ed.2d at 32 (Harlan, J., concurring). Justice Harlan’s concurrence treated the subject thoroughly, referring to Sullivan and noting that compelled self-disclosure was essential to the government’s legitimate taxing power. Id. at 436, 455, 91 S.Ct. at 1541, 1551, 29 L.Ed.2d at 24, 33. The facially neutral character of the questions on a tax return and their direction to the public at large, for an essentially non-criminal purpose, minimize the hazards of self-incrimination and thus justify this limitation upon the assertion of the privilege. Id. at 429-32, 91 S.Ct. at 1538-1540, 29 L.Ed.2d at 18-19.
This does not prohibit a person from claiming his Fifth Amendment privilege by specific answer to selected individual questions on the return. United States v. Sullivan, 274 U.S. at 263-64, 47 S.Ct. at 607-608, 71 L.Ed. at 1039-40; United States v. Malnik, 489 F.2d 682, 685 (5th Cir.), cert. denied, 419 U.S. 826, 95 S.Ct. 44, 42 L.Ed.2d 50 (1974). The inquiry does not end, however, with assertion of the privilege in response to a specific question.5 Thus, the taxpayer bears some burden of asserting facts which will indicate to the judge that the answer to each question for which the privilege is asserted may incriminate him, or at least it must be apparent from the context of the question that such is the case. While this burden is not great,6 the taxpayer is not [1161]*1161excused from answering where there is no evidence of any “substantial and ‘real’ ”, as opposed to “trifling or imaginary”, hazard of incrimination. Marchetti v. United States, 390 U.S. 39, 53, 88 S.Ct. 697, 705, 19 L.Ed.2d 889, 901 (1968); E.L.L. v. State, 572 P.2d 786, 788 (Alaska 1977).7
In United States v. Brown, 600 F.2d 248 (10th Cir.), cert. denied, 444 U.S. 917, 100 S.Ct. 233, 62 L.Ed.2d 172 (1979), the court commented:
The appellant here is not aided by Garner and Sullivan because he attempts to use the Fifth Amendment to avoid disclosing even the amount of his income and this is not protected by the Fifth Amendment. Instead it is a simple attempt to prevent the communication to the government of the amount of the tax. Necessarily it is an illegal effort to stretch the Fifth Amendment to include a taxpayer who wishes to avoid filing a return ....
[T]he claim of privilege is not allowed to accomplish avoiding the disclosure of information as to tax liability. After all, the entire theory of income tax is based upon individual disclosure, and the compelling of income tax filing is fully recognized as not violating the Fifth Amendment.
Id. at 252 (footnotes omitted).
The only suggestion of any potential for incrimination in the cases at bar is that of criminal prosecution for willful failure to file or to pay tax, if the parties in fact have sufficient income to be required to file a return and they owe the State of Alaska any money. But claiming a right to refuse to disclose income information in a return on the grounds that it will establish tax liability and thus the potential for criminal prosecution for disobedience to the income tax laws is a bootstrapping argument that could defeat the legitimate power of the government to tax income. It has been explicitly rejected in United States v. Brown, id. at 251-52, and also in Daly v. United States, 393 F.2d 873, 877 (8th Cir. 1968).8 Neither Pickles nor the Olivers [1162]*1162have expressly made this contention in these appeals.
B. Resistance to the administrative summonses.
Here the state has not prosecuted the taxpayers for failure to file a return. Instead, the state has sought to determine the tax liability of the Olivers and of Pickles by compelling their testimony and production of their records through administrative summonses. There is a split of authority whether the potential of criminal prosecution for tax violations, which does not justify a blanket refusal to file returns, may justify refusal to comply with a summons.
The superior court below relied on United States v. Daly, 68-2 U.S. Tax Cas. (CCH) ¶ 9617 (D.Minn.1968).9 In that case, the district court, after remand, reversed its own contempt order following Daly’s refusal, on the basis of his privilege against self-incrimination, to answer a series of questions propounded to him because “[a]s to each question asked, it is evident from the implications of the question in the setting in which asked that a responsive answer to the question may tend to incriminate Jerome Daly.” Id., 68-2 U.S. Tax Cas. (CCH) at 88,123. The transcript of those proceedings, supplied to us in the record, reveals that the judge’s position in that case was that the IRS, when faced with a tax return containing conclusory assertions of the privilege against self-incrimination instead of income information, may prosecute for failure to file a return, but it may not compel answers to the questions in that return as long as a sufficient showing of a tendency to incriminate is made. This ruling was not appealed to the Eighth Circuit.
One court of appeals has stated, however, that its decision to give effect to an administrative summons for financial records relevant to civil proceedings for collection of income tax was “squarely planted” on a representation by the IRS that the investigation had no purpose of eventual criminal prosecution, and ruled that no information obtained under the summons could be used for such prosecution; this may indicate that, absent this assurance, the court would not have found the summons to be enforceable. Hinchcliff v. Clark, 371 F.2d 697, 701 (6th Cir.), cert. denied, 387 U.S. 941, 87 S.Ct. 2073, 18 L.Ed.2d 1327 (1967).
More recent cases have taken a contrary position. In United States v. French, 442 F.Supp. 166 (N.D. Iowa 1977), aff’d, 567 F.2d 351 (8th Cir. 1978), the court enforced an IRS summons because, “[e]ven if the records could later be used for criminal prosecution, where the initial investigation is civil in nature and no criminal investigation has been initiated, the fifth amendment will not bar production. Only where the sole purpose of the investigation is criminal may production be successfully challenged.” Id. at 168 (citation omitted). Other cases have upheld such summonses [1163]*1163without inquiry as to the nature of the investigation. Russell v. United States, 524 F.2d 1152 (8th Cir. 1976); United States v. Ponder, 475 F.2d 37 (5th Cir. 1973).
We must reject the Daly position. If the court is convinced that the responses to be evoked from the taxpayer, whether on the tax return or in response to a summons or subpoena, would tend to incriminate the taxpayer, then those responses ought to be privileged in both contexts. The Daly court held that such responses would be privileged for purposes of the summons, but not for the tax return. We think this inconsistent; the Supreme Court has clearly indicated that, if truthful answers to particular questions on the tax return would tend to incriminate the individual, then the privilege can be validly claimed as to those questions in a prosecution for failure to file. Thus, if the court in Daly found that a responsive answer would tend to incriminate the individual, then the prosecution for failure to file, as well as the contempt order, should have failed. Conversely, if the prosecution for failure to file was valid, then the contempt order should also have been.
Thus, since we have concluded that the taxpayers here made an insufficient showing of a substantial and real hazard of incrimination as to their failures to respond to questions on the tax return, which is tantamount to a failure to file, we must reach the same conclusion as to their failures to comply with the administrative summonses. Whether the government demand is for written answers on a return, oral responses to a revenue agent’s questions, or records which establish the amount of income, the Fifth Amendment question is the same — whether the answer to a specific question or the production of a particular document poses a real hazard that the taxpayer will be exposed to criminal prosecution through his own testimony. Whether prosecuted for failing to file a return or jailed for civil contempt, the taxpayer is suffering a penalty for refusing to provide the information. But sustaining a claim of the privilege to prevent prosecution either for failing to provide the information on the form in the first place or for tax evasion runs against the doctrine of Byers.10
In our view Pickles’s and the Olivers’ self-incrimination claims based on the United States and Alaska Constitutions must be rejected. Neither Pickles nor the Olivers have shown any real hazard of incrimination in the context of investigations to determine civil tax liability.11
C. In camera hearings.
In the course of both proceedings below, it was suggested that the taxpayers [1164]*1164might better be able to articulate their specific objections to the questions if given the opportunity to explain their positions to the judge iri camera. The state in both cases indicated its willingness to acquiesce.
From the records before us, it appears that the Olivers were informed that they had a right to an in camera hearing and did not choose to pursue it. Pickles, on the other hand, expressed a desire for an in camera hearing without having been explicitly informed that he had a right to such a hearing, and his request, although never formally denied, was not granted.12
We think that this denial requires a remand of Pickles’s contempt citation. He should be given an opportunity for an in camera hearing,13 and, if it appears to the superior court that his objections to the particular questions, as articulated in this hearing, do meet the standards laid out above, then his contempt citation should be vacated.
On the other hand, since the Olivers turned down an offer for an in camera hearing, this holding does not affect the validity of their citation.14
V. Whether the Department of Revenue’s summons violated Pickles’s rights against unreasonable searches and seizures.15
The Fourth Amendment to the United States Constitution and its Alaskan counter[1165]*1165part, Alaska Const. art. 1, § 14, both protect a person’s papers against “unreasonable searches and seizures.” The Fourth Amendment’s role as an absolute prohibition against seizure of documents considered to be within the sphere of “private” or “personal” papers of an individual, regardless of whether their production is compelled by subpoena or actual seizure, traces back to Boyd v. United States, 116 U.S. 616, 621-22, 6 S.Ct. 524, 527-528, 29 L.Ed. 746, 748 (1886).16 This doctrine has been eviscerated through the years as the Supreme Court, in cases involving electronic eavesdropping and more traditional intrusions on privacy, has moved away from a consideration of the nature of the evidence “seized” to an analysis of the procedural safeguards under which the seizure occurred.17 Andresen v. Maryland, 427 U.S. 463, 96 S.Ct. 2737, 49 L.Ed.2d 627 (1976), explicitly considering the Fifth Amendment and procedural safeguards associated with search and seizure, is indicative of this trend, holding that business records prepared by a sole practitioner lawyer for his own use could be seized from his possession so long as the warrant for the search of his office met the requirements of probable cause and specificity, and the other procedural requisites of reasonableness delineated in past cases. 427 U.S. at 474, 96 S.Ct. at 2745, 49 L.Ed.2d at 639.18
Pickles maintains that the summons was unreasonable because it constituted a “warrantless” search, or a “fishing expedition.” This argument seems misguided. Although Boyd v. United States equated the forced production of documents through subpoena with a seizure, 116 U.S. at 621-22, 6 S.Ct. at 527-528, 29 L.Ed. at 748, this rationale is no longer followed with respect to an administrative summons:
Neither the literal language of the [Fourth] Amendment nor the history which led to its adoption supports the idea that the Amendment limits the use of judicially enforceable subpenas which require testimony or the production of designated books and records....
Except for limitations concerning breadth and relevancy, the Fourth Amendment does not now restrict an administrative subpoena for records or an administrative requirement of reports.
1 K. Davis, Administrative Law Treatise § 3.05, at 180-81 (1958) (footnotes omitted).19
[1166]*1166Furthermore, arguments paralleling Pickles’s unlawful search and seizure contentions have been rejected in cases where private records comparable to those sought here were subpoenaed by the IRS from the possession of an individual taxpayer. United States v. Silkman, 543 F.2d 1218 (8th Cir. 1976), cert. denied, 431 U.S. 919, 97 S.Ct. 2185, 53 L.Ed.2d 230 (1977); United States v. DeGrosa, 405 F.2d 926 (3d Cir.), cert. denied, 394 U.S. 973, 89 S.Ct. 1465, 22 L.Ed.2d 753 (1969). See also United States v. French, 442 F.Supp. 166 (N.D.Iowa 1977).
In light of the foregoing, we conclude that since the summons in the Pickles case is reasonably specific, asks only for material relevant to a legitimate tax inquiry, and is enforceable only by court order, Pickles’s search and seizure claims under the federal and Alaska constitutions must be rejected.
VI. Whether enforcement of the summonses would violate Pickles’s and the Olivers’ right to privacy embodied in art. I, § 22 of the Alaska Constitution.
Both Pickles and the Olivers also argue that compelled production of their records would violate the explicit protection of privacy granted in Alaska Const. art. I, § 22.20 Our past decisions indicate that this protection may go beyond that afforded by the penumbral rights associated with the federal constitution. State v. Glass, 583 P.2d 872, 878-79 (Alaska 1978) [“Glass I”]. The state concedes that an individual’s privacy interest in the information sought is within the zone of privacy protected by art. I, § 22, and language in Glass I alludes to personal finances as one kind of information within an individual’s expectation of privacy. Glass I, 583 P.2d at 878.
The protection given to interests within this provision’s scope is not absolute, however. Ravin v. State, 537 P.2d 494, 504 (Alaska 1975). The required level of justification turns on the precise nature of the privacy interest involved. Falcon v. Alaska Public Offices Commission, 570 P.2d 469, 476 (Alaska 1977). The question involves a balancing of “the nature and extent of the privacy invasion and the strength of the state interest requiring disclosure.” Id. Falcon indicates that even where the state interest is sufficiently compelling to justify intrusion upon the individual’s interest, the invasion must be carried out “by the least intrusive method.” Id. at 477.
[1167]*1167The state cites cases, several of which have been noted previously, which recognize the necessity of self-reporting and enforceable investigation processes to the operation of the income tax system,21 and the validity of the state’s power to tax incomes. The state also emphasizes that the degree of invasion of privacy in this case is not as great as the invasion in issue in Falcon, which held that a conflict of interest law which had the effect of requiring a doctor to disclose the names of his patients violated art. I, § 22 in the absence of regulations fashioned to protect certain classes of physicians’ patients. The distinction argued is that the disclosure does not violate a traditional privilege associated with confidentiality, as between doctor and patient, and that the confidentiality of tax information is protected by statute in AS 43.05.230, a limitation upon disclosure which Falcon recognized would reduce the degree of invasion of privacy. 570 P.2d at 479.
In light of the unchallenged validity of the state’s taxing power and the agreement among the cases that self-disclosure and the accompanying power to summon records is necessary to implement the tax system, we conclude that the state has a compelling interest justifying the invasion of privacy sought here. Given the lack of connection between most information sought on a tax return and a person’s more intimate concerns and the confidentiality protections afforded by AS 43.05.230, we further conclude that this interest outweighs any privacy rights violated by compulsion to fill out the form or testify before a revenue agent.
We also conclude that, generally, self-disclosure, accompanied by appropriate use of the summons power, constitutes the least intrusive method of obtaining the information. We think it appropriate to note, however, that the strength of the privacy interest may vary with the nature of the financial records sought, and that this must be taken into account in ascertaining the “least intrusive method.” Most of the records sought by the government fall into the category of records in which the legitimate expectation of privacy is lowered because such records, in the course of their use, are bound to be seen by others.22 The records demanded of the Olivers were W-2 forms or other pay records received from employers, bank statements, credit union statements, and copies of federal tax returns, all of which fall within this category. The summons directed at Pickles was worded more broadly, directing him to produce “all books, records, and papers necessary to determine the correct Alaska Individual Net Income Tax Liability for the year 1977. This may include but is not limited to the following: cash receipts and disbursement records, checking and saving account records, stock and real estate records, all W-2 forms or pay records from all employers[,] workpapers, ledgers, journals, etc.”
In accordance with the principle that the information must be obtained by the least obtrusive means, we think that the scope of this summons must be limited to require submission only of those of Pickles’s papers, journals, ledgers, and the like which, in the course of their use, would be seen by other people not in a confidential relationship with him (e. g., attorneys). It has not yet been shown that Pickles’s tax liability cannot be determined on the basis of these “public” papers, and although we have grave doubts concerning the permissibility of summonsing “purely private” papers in the event that the tax liability cannot be determined without them, we do not decide that issue at this time. Under this interpretation, such items as checking and savings account records, W-2 forms, or other pay records must be produced under the [1168]*1168summons. We reserve judgment on the permissibility of requiring the production of “purely private” papers until such time as it has been shown that the tax liability cannot be computed from the “public” papers alone and the issue has been presented and argued to us.
VII. Conclusion.
The taxpayers in the cases before us are correct in arguing that the Department of Revenue, in its information-gathering activities, must demonstrate a due regard for individuals’ privacy rights and the privilege against self-incrimination. To expand these rights to the extent urged by the taxpayers, however, would render unworkable virtually any income tax system.
The taxpayers readily acknowledge that fact, and, indeed, urge this court to enable Alaska to become “the seventh flame in a beacon that will lead our country back into the heady brilliance of personal liberty from the gathering dusk of progressive tryanny” by striking down Alaska’s personal income tax. The most straightforward response to the taxpayers here is that such a decision is properly one for the legislature, not the judiciary. Indeed, the legislature has accomplished exactly the result advocated by these litigants.23 This court is not empowered to prohibit an income tax, for our role is limited to ensuring that whatever income tax the legislature chooses to enact does not contravene the privilege against self-incrimination, the right to privacy, and other provisions of the federal and Alaska constitutions.
The superior court judgment in each case is REVERSED and REMANDED^ for further proceedings consistent with this opin-, ion.
