I. FACTS AND PROCEEDINGS BELOW

1
The facts of this case are not in dispute. The Internal Revenue Service ("IRS") reassessed the Jacksons' federal income  tax liabilities for the 1982, 1983, and 1989 tax years, but the  Jacksons did not notify the California Franchise Tax Board  ("Board") of the federal reassessments as they were required  to do under California law. The Jacksons filed for bankruptcy  in 1996 and the Board filed a proof of claim for unpaid state  income taxes for the '82, '83, and '89 tax years based upon  the IRS reassessments. The Jacksons objected to the Board's  claim and the bankruptcy court sustained the Jacksons' objection disallowing the Board's claim for state income taxes. The  United States District Court for the Central District of California affirmed the bankruptcy court's order concluding that the  Jacksons' California tax liabilities were discharged despite the  fact that the Jacksons failed to report the IRS reassessments  to the Board. The district court reasoned that the failure to  report a tax reassessment did not constitute a failure to file a  tax return and, therefore, the Jacksons' California tax liabilities were not excepted from the bankruptcy code's discharge  provisions. The Board appeals from the district court's judg- ment. We have jurisdiction under 28 U.S.C. S 158(d) and  affirm.

II. DISCUSSION
A. ELEVENTH AMENDMENT SOVEREIGN IMMUNITY

2
Neither party has discussed or raised the Eleventh  Amendment sovereign immunity issue this case presents, but  we must resolve that issue before we reach the merits of this  case. See Edelman v. Jordan, 415 U.S. 651, 677-78 (1974);  Charley's Taxi Radio Dispatch Corp. v. Sida of Hawaii, Inc.,  810 F.2d 869, 873 n.2 (9th Cir. 1987). Eleventh Amendment  sovereign immunity limits the jurisdiction of the federal  courts and can be raised by a party at any time during judicial  proceedings or by the court sua sponte. See Edelman, 415  U.S. at 677-78; Charley's Taxi Radio Dispatch Corp., 810  F.2d 873 n.2. Unlike other jurisdictional limitations, Congress  can abrogate Eleventh Amendment sovereign immunity  through the Fourteenth Amendment and states can waive their  Eleventh Amendment sovereign immunity and consent to federal jurisdiction. Seminole Tribe of Florida v. Florida, 517  U.S. 44, 55 (1996); Atascadero State Hospital v. Scanlon, 473  U.S. 234, 238 (1985); BV Engineering v. University of California, Los Angeles, 858 F.2d 1394, 1395-96 (9th Cir. 1988).

The Eleventh Amendment provides:

3
The Judicial power of the United States shall not be construed to extend to any suit in law or equity, commenced or prosecuted against one of the United States by Citizens of another State, or by Citizens or Subjects of any Foreign State.


4
U.S. Const. amend. XI. Despite its narrow language, the Eleventh Amendment bars suits in federal court against a state and  its agencies brought by its own citizens and citizens of other  states. Edelman, 415 U.S. at 662-63; Hans v. Louisiana, 134  U.S. 1, 9-21 (1890); Franceschi v. Schwartz, 57 F.3d 828, 831  (9th Cir. 1995). The State of California has not made a general waiver of its Eleventh Amendment sovereign immunity,  see Atascadero State Hospital, 473 U.S. at 241, and will only  be deemed to have done so in this case if it has unequivocally  expressed its consent to federal jurisdiction. Actmedia, Inc. v.  Stroh, 830 F.2d 957, 963 (9th Cir. 1986). The Board waived  its Eleventh Amendment sovereign immunity in this case  when it filed a proof of claim for unpaid state income taxes.


5
Section 106(b) of the Bankruptcy Code provides:


6
A governmental unit that has filed a proof of claim in the case is deemed to have waived sovereign immunity with respect to a claim against such gov ernmental unit that is property of the estate and that arose out of the same transaction or occurrence out of which the claim of such governmental unit arose.


7
11 U.S.C. S 106(b). Section 106(b) codifies the Supreme  Court's decision in Gardner v. New Jersey, 329 U.S. 565  (1947), which held that a state waives its sovereign immunity  when it files a proof of claim in a bankruptcy proceeding. Id.  at 573-74. The Supreme Court stated:


8
It is traditional bankruptcy law that he who invokes the aid of the bankruptcy court by offering a proof of claim and demanding its allowance must abide the consequences of that procedure. . . . When the State becomes the actor and files a claim against the fund, it waives any immunity which it otherwise might have had respecting the adjudication of the claim.


9
Id. at 573-74. The Board waived its Eleventh Amendment  sovereign immunity in regard to the bankruptcy court's determination that the Jacksons' tax liability debts were dischargeable because the Board filed a proof of claim in this case for  unpaid state income taxes and the Jacksons only objected to  the Board's claim that their tax liability debts were nondischargeable.


10
Relying on the Supreme Court's decision in Seminole Tribe  of Florida v. Florida, 517 U.S. 44, 66-72 (1996) (Congress  cannot use its Article I powers to abrogate Eleventh Amendment sovereign immunity), the Fourth Circuit has held that  S 106(b) amounts to an unconstitutional attempt by Congress  to abrogate the sovereign immunity of the states. See In re  Creative Goldsmiths, 119 F.3d 1140, 1147 (1997), cert. denied, _______ U.S._______, 118 S. Ct. 1517 (1998). The Fourth Circuit stated:


11
While 11 U.S.C. S 106(b) may correctly describe those actions that, as a matter of constitutional law, constitute a state's waiver of the Eleventh Amend ment, it is nevertheless not within the Congress' power to abrogate such immunity by "deeming" a waiver. Rather, in the absence of a constitutional authorization, it lies solely within a state's sovereign power to waive its immunity voluntarily and to con sent to federal jurisdiction. Only if it waives such immunity may a private citizen sue the state in fed eral court.


12
Id. at 1147. Despite holding S 106(b) unconstitutional, the  Fourth Circuit recognized, consistent with Gardner v. New  Jersey, that, when a state files a proof of claim in a bankruptcy proceeding, the state waives its sovereign immunity in  regard to the debtor's claims which arise out of the same  transaction or occurrence as the state's proof of claim. Id. at  1148.


13
In contrast to the Fourth Circuit's decision in In re Creative  Goldsmiths, the Tenth Circuit has held thatS 106(b) is not  affected by the Supreme Court's decision in Seminole Tribe.  See In re Straight, 143 F.3d 1387 (10th Cir. 1998). The Tenth  Circuit stated:


14
[Section] 106(b) does not pretend to abrogate a state's immunity, it merely codifies an existing equi table circumstance under which a state can choose to preserve its immunity by not participating in a bank ruptcy proceeding or to partially waive that immu nity by filing a claim. The choice is left to the state. Thus, S 106(b) follows the lead already established by the Supreme Court in Gardner v. New Jersey .


15
Id. at 1392.


16
We decline to address the issue of whether S 106(b) is constitutional because the Board's conduct falls squarely under  the Supreme Court's decision in Gardner v. New Jersey. See  Crowder v. Kitagawa, 81 F.3d 1480, 1486 (9th Cir. 1996) ("It  is `a fundamental rule of judicial restraint' that federal courts  `ought not pass on questions of constitutionality. . . unless  such adjudication is unavoidable.' ") (quoting Jean v. Nelson,  472 U.S. 846, 854 (1985)). The Seventh and Eleventh Circuits  recently declined to address the constitutionality of S 106(b)  and instead relied exclusively on Gardner v. New Jersey to  conclude that a state waives its sovereign immunity when it  files a proof of claim in a bankruptcy proceeding. See In re  Burke, 146 F.3d 1313, 1317-20 (11th Cir. 1998); In re Platter,  140 F.3d 676, 678-80 (7th Cir. 1998). We follow the lead of  the Seventh and Eleventh Circuits and conclude that, based  upon the Supreme Court's decision in Gardner v. New Jersey,  the Board waived its sovereign immunity in this case when it  filed a proof of claim for unpaid state income taxes against the Jacksons.1 The federal courts have jurisdiction to hear this  case and we must determine whether the Jacksons' tax liability debts are excepted from the Bankruptcy Code's discharge  provisions.


17
B. DISCHARGEABILITY OF THE JACKSONS' STATE INCOME TAX LIABILITY


18
The bankruptcy court's interpretation of the Bankruptcy  Code is reviewed de novo, In re Federated Group, Inc., 107  F.3d 730, 732 (9th Cir. 1997); In re Harrell, 73 F.3d 218, 219  (9th Cir. 1996)(per curiam), and we review the district court's  decisions on an appeal from a bankruptcy court de novo  applying the same standard of review applied by the district  court. In re Wilbur, 126 F.3d 1218, 1219 (9th Cir. 1997); In   re Claremont Acquisition Corp., 113 F.3d 1029, 1031 (9th  Cir. 1997).


19
Section 523 of the Bankruptcy Code2 excepts from the Bankruptcy Code's discharge provisions a tax liability debt if:  (1) the tax underlying the tax liability debt required a return;  and (2) the debtor failed to file the required return. See 11  U.S.C. S 523 (a)(1)(B)(i). Former section 18451 of the California Revenue and Taxation Code3 required a taxpayer to  report to the Board any reassessment made by the IRS if the  reassessment affected the taxpayer's tax liability and required  a taxpayer to file an amended return with the Board if the taxpayer filed an amended return with the IRS. See  Cal. Rev. &  Tax. Code S 18451.


20
The Board argues that the debtors' failure to report IRS  reassessments pursuant to S 18451 is the equivalent of a failure to file a return, and, therefore, the debtors' state income  tax liabilities are excepted from the Bankruptcy Code's discharge provisions. The Jacksons argue that the filing of a  report pursuant to S 18451 is not the equivalent of the filing  of a return, and, therefore, their state tax liabilities are dischargeable under the Bankruptcy Code's discharge provisions. The filing of a report under S 18451 is not the  equivalent of the filing of a return and the Jacksons' tax liability debts are dischargeable.


21
Statutory interpretation begins with the plain meaning  of the statute's language. In re Bonner Mall Partnership, 2  F.3d 899, 908 (9th Cir. 1993). When the statutory language is clear and consistent with the statutory scheme at issue, the  statute's plain language is conclusive and this Court need not  inquire beyond the plain language of the statute. United States  v. Hunter, 101 F.3d 82, 84 (9th Cir. 1996); In re Bonner Mall  Partnership, 2 F.3d at 908. The Jacksons' tax liability debts  are not excepted from discharge pursuant to S 523(a)(1)(B)(i)  because the plain language of S 523(a)(1)(B)(i) excepts tax  debts from discharge only when a required return is not filed  and the plain language of S 18451 did not require the Jacksons to file a return with the Board.


22
The Board's argument that the term "return" in S 523  includes a tax report that is required by S 18451 ignores the  principle that "exceptions to dischargeability should be  strictly construed in order to preserve the Bankruptcy Act's  purpose of giving debtors a fresh start." Matter of Kasler, 611  F.2d 308, 310 (9th Cir. 1979) (citing Gleason v. Thaw, 236  U.S. 558, 562 (1915)). A return is "a formal statement on a  required legal form showing taxable income, allowable  deductions and exemptions and the computation of the tax  due." Webster's Ninth New Collegiate Dictionary 1008  (1985). A strict construction of the plain meaning of the term  return mandates the conclusion that a report required by  S 18451 does not constitute a return. Section 18451 only  requires a taxpayer to report an IRS reassessment and does  not require the taxpayer to follow the formalities of filing a  full return. The Jacksons did fail to file reports that were  required by S 18451, but they did not fail to file returns.


23
Section 18451 itself even recognizes a difference  between reports and returns. Section 18451 requires a report  when the IRS makes a reassessment and the reassessment  affects the taxpayer's tax liability but requires an amended  return when the taxpayer files an amended return with the  IRS. Because S 18451 requires a report under some circumstances yet requires an amended return under different circumstances, S 18451 unequivocally distinguishes informal  reports from formal returns.


24
The Board relies on In re Blutter, 177 B.R. 209 (Bank.  S.D.N.Y. 1995), to support its argument that the Jacksons'  failure to report an IRS reassessment pursuant toS 18451 renders their tax liability debts non-dischargeable. In Blutter, the  bankruptcy court rejected the argument that a report was not  a return and concluded that the debtor's failure to report a tax  reassessment rendered the debtor's tax liability debt nondischargeable. In re Blutter, 177 B.R. at 211-12. The court  reasoned that "a debtor should not be rewarded with a discharge for failing to comply with his filing obligations . . .."  Id. at 211. The reasoning in Blotter must be rejected because  it ignores other provisions of the Bankruptcy Code that  address violations of tax laws by debtors.


25
[7] The mere failure to comply with tax laws or filing obligations does not automatically render a tax liability debt nondischargeable under the Bankruptcy Code. The Bankruptcy  Code defines when a failure to comply with tax laws, besides  a failure to file a return, renders a tax liability debt nondischargeable. Section 523(a)(1)(C) excepts from discharge tax liability debts "with respect to which the debtor made a  fraudulent return or willfully attempted in any manner to  evade or defeat such tax." 11 U.S.C. S 523(a)(1)(C) (emphasis  added). Section 523(a)(1)(B)(i) would render S 523(a)(1)(C)  superfluous if S 523(a)(1)(B)(i) encompassed every tax law  violation like the Jacksons' failure to report the IRS reassessment. Section 523(a)(1)(B)(i) cannot be read so broadly as to  render S 523(a)(1)(C) superfluous because all statutory provisions must be given meaning and effect. See Burrey v. Pacific  Gas & Elec. Co, 159 F.3d 388, 394 (9th Cir. 1998) ("In interpreting a statutory provision, we must avoid any construction  that renders some of its language superfluous."). A violation  of a tax law that is not a failure to file a return must be a willful attempt to evade or defeat the tax at issue to render the  underlying tax liability debt non-dischargeable. The Jacksons  only failed to file a report and nothing in the record suggests  that they willfully attempted to evade or defeat the underlying  state income taxes. Their tax liability debts cannot be  excepted from the Bankruptcy Code's discharge provisions  pursuant to S 523(a)(1)(B)(i).


26
The rationale and policy positions that underlie S 523(a)  (1)(B)(i) further support the conclusion that the Jacksons' tax  liability debts are not excepted from discharge."The policy  behind this subsection is that a debtor should not be permitted  to discharge a tax liability based upon a required tax return  that was never filed." 3 Norton Bankruptcy Law and Practice  2d S 47:6, 47-15 (1997) (emphasis added). This case does not  present a situation where a required tax return was never filed because the Jacksons did file their original tax returns and,  contrary to the Board's assertions, the rationale and policy  considerations that underlie S 523(a)(1)(B)(i) do not support  the conclusion that the Jacksons' failure to report the IRS  reassessments constituted a failure to file a tax return.


27
Other courts have also concluded that tax liability debts are  not excepted from bankruptcy discharge when a debtor fails  to comply with a notice statute. See In re Dyer , 158 B.R. 904,  906 (Bank. W.D.N.Y. 1993) ("dischargeable taxes are not  converted into non-dischargeable taxes by a State's`requiring' successive returns (`amended returns') addressing the  same basic information, or by a State's labelling all `amendments' or `notifications' as `returns.' "); In re Blackwell, 115  B.R. 86 (Bank. W.D. Va. 1990) (requiring taxpayer to report  IRS reassessment is not the equivalent of requiring a return).  In both Dyer and Blackwell the bankruptcy courts noted that  exceptions to discharge must be construed narrowly and  refused to construe S 523(a)(1)(B)(i) beyond its plain language. In re Dyer, 158 B.R. at 906; In re Blackwell, 115 B.R.  at 88-89. The bankruptcy court in In re Dyer concluded:  "Once a debtor has filed `a return' for a tax which is  `required' to be so reported that provision [S 523(a)(1)(B)(i)]  has been met. . . . Once a requirement has been satisfied, it  does not become `un-' satisfied because some new requirement has been superadded." In re Dyer, 158 B.R. at 906. The  reasoning of the bankruptcy courts in Dyer and Blackwell is  persuasive.


28
The Jacksons' failure to file a report does not fall within the plain language of S 523(a)(1)(B)(i) and nothing in the record  indicates that the Jacksons failed to report the IRS reassessments to the Board to evade state income taxes. The Jacksons'  tax liability debts are not excepted from the Bankruptcy  Code's discharge provisions.

III. CONCLUSION

29
The Board waived its Eleventh Amendment sovereign  immunity in this case when it filed a proof of claim against  the Jacksonsfor unpaid taxes and the bankruptcy court and  the district court correctly concluded that the Jacksons' tax  liability debts were dischargeable.


30
AFFIRMED.



Notes:


1
 It should be noted that the State has made no attempt to assert Eleventh  Amendment sovereign immunity in this case and that we have addressed  the sovereign immunity issue to end uncertainty that may exist regarding  the validity of Gardner.
