On April 21, 2006, petitioner filed a petition in this Court challenging respondent's determinations. In his petition, petitioner wrote: "No tax liability! The IRS did not calculate my itemized deductions nor " [sic] additional two dependents."

On January 29, 2007, a hearing before Chief Special Trial Judge Peter J. Panuthos of this Court was held involving: (1) Petitioner's oral motion to withdraw his petition, (2) petitioner's oral motion to continue the case, (3) respondent's motion to dismiss on jurisdictional grounds petitioner's claims regarding (i) respondent's decision letter sustaining respondent's intent to collect petitioner's 2000 unpaid income tax liability by levy and (ii) sustaining the lien filed by respondent with respect to the section 6702 frivolous income tax return penalty for 2002, and (4) respondent's motion for summary judgment. At that hearing petitioner announced his intention to retain counsel. At the conclusion of the hearing Chief Special Trial Judge Panuthos took each of the aforementioned motions under advisement except for petitioner's motion to continue the case, which was denied by Order dated January 29, 2007. By a 2009 Tax Ct. Memo LEXIS 114">*123 second Order, dated March 13, 2007, Chief Special Trial Judge Panuthos dismissed for lack of jurisdiction petitioner's challenge regarding respondent's filing of a tax lien against petitioner with respect to the collection of the penalty under section 6702 as well as respondent's intent to levy on petitioner's property for his unpaid 2000 taxes.

On April 23, 2007, a hearing before Special Trial Judge Robert N. Armen, Jr., of this Court was held with regard to: (1) Petitioner's motion to withdraw his petition, and (2) respondent's motion for summary judgment. Petitioner repeated his prior stated intention to retain counsel and orally moved that he be allowed to withdraw his motion to withdraw his petition. In an Order dated April 23, 2007, Special Trial Judge Armen, among other things (1) denied respondent's motion for summary judgment without prejudice, (2) granted petitioner's oral motion to withdraw his motion to withdraw the petition, (3) remanded the case to respondent's Office of Appeals for consideration of: (i) The basis for the February 17, 2003, assessment with respect to tax year 2000, and (ii) the effect, if any, of petitioner's discharge in bankruptcy on petitioner's unpaid 2009 Tax Ct. Memo LEXIS 114">*124 tax liabilities for 2000 and 2002, and (4) ordered petitioner to file a response with the Court stating unequivocally: (i) Whether petitioner received, or did not receive, a notice of deficiency determining a deficiency and penalty in his Federal income tax for 2000, (ii) whether petitioner received, or did not receive, a notice of deficiency determining a deficiency in his Federal income tax for 2002, and, if petitioner admits that he did receive such a notice of deficiency for either or both of those years, (iii) why petitioner did not file a petition for redetermination of the deficiency and penalty with the Court. Special Trial Judge Armen's Order stated that if petitioner did not unequivocally answer the aforementioned questions, such failure would be deemed to be an admission that petitioner did receive notices of deficiency for those years.

On May 29, 2007, a representative of respondent and petitioner held a telephone supplemental section 6330 hearing. On August 15, 2007, respondent's Appeals Office issued a supplemental notice of determination, in which respondent determined that a notice of deficiency was properly mailed to petitioner for tax year 2000. The supplemental notice 2009 Tax Ct. Memo LEXIS 114">*125 of determination stated that the TXMOD transcript shows that petitioner was issued a CP 2000 notice. The CP 2000 notice proposed changes to petitioner's 2000 income tax return and provided instructions regarding what petitioner should do if he agreed or disagreed with the changes. Respondent's determination was based on transaction code 922 on the TXMOD transcript, which indicates a CP 2000 case. Moreover, the process codes on the TXMOD transcript included code 75, which indicates that a notice of deficiency for 2000 was issued, and code 90, which indicates that a deficiency for 2000 was assessed by default on February 17, 2003.

Respondent concluded that petitioner's bankruptcy filing did not affect petitioner's 2000 and 2002 Federal income tax liabilities. The attachment to the supplemental notice of determination stated that the Appeals settlement officer verified that the filing of the notice of Federal tax lien was in accordance with all legal and procedural requirements and that the requirement set forth in section 6330(c)(3)(C) that the filing of the tax lien "balances the need for the efficient collection of taxes with the legitimate concern of the person that any collection 2009 Tax Ct. Memo LEXIS 114">*126 action be no more intrusive than necessary" was satisfied.

Petitioner filed his report with the Court on August 16, 2007, stating:

As to this Court's first 3-part question (1) Regarding tax year 2000, I do remember receiving some type of tax reassessment from the IRS to which I immediately disputed and appealed through the IRS toll-free telephone system along with follow-up letters, previously submitted as exhibits in support thereof, in the instant case; and (2) Yes for 2002, I did receive that notice;

and (3) I thought I had or did file for re-determination.

At the trial held on December 10, 2008, petitioner reiterated his desire to seek counsel. The trial was then recessed to permit petitioner to contact an attorney, but after a few minutes petitioner abandoned the effort. As stated supra p. 2, petitioner declined to testify despite several entreaties by the Court to do so.

A. Standard of Review

The judicial review that we are required to conduct focuses on the determination made by respondent. Unless the underlying tax liability of the taxpayer in such a proceeding is properly at issue, we review the Commissioner's determination for abuse of discretion. Sego v. Commissioner, 114 T.C. 604">114 T.C. 604, 114 T.C. 604">610 (2000); 2009 Tax Ct. Memo LEXIS 114">*127 Goza v. Commissioner, 114 T.C. 176">114 T.C. 176 (2000). An abuse of discretion is defined as any action that is unreasonable, arbitrary or capricious, clearly unlawful, or lacking sound basis in fact or law. Thor Power Tool Co. v. Commissioner, 439 U.S. 522">439 U.S. 522, 439 U.S. 522">532-533, 99 S. Ct. 773">99 S. Ct. 773, 58 L. Ed. 2d 785">58 L. Ed. 2d 785 (1979); Woodral v. Commissioner, 112 T.C. 19">112 T.C. 19, 112 T.C. 19">23 (1999).

At the collection hearing a taxpayer may raise any relevant issues relating to the unpaid tax, including spousal defenses, challenges to the appropriateness of the collection action, and offers of collection alternatives. In addition, he may challenge the existence or amount of the underlying tax liability, but only if he did not receive a notice of deficiency or otherwise have an opportunity to dispute the liability. Sec. 6330(c)(2)(B); sec. 301.6330-1(e)(3), Q&A-E2, Proced. & Admin. Regs.

In making a determination following a collection hearing, the Commissioner must consider: (1) Whether the requirements of any applicable law or administrative procedure have been met, (2) any relevant issues raised by the taxpayer, and (3) whether the proposed collection action balances the need for efficient collection of taxes with the legitimate concern that the collection action be no more 2009 Tax Ct. Memo LEXIS 114">*128 intrusive than necessary. Sec. 6330(c)(3).

B. Issuance of the Notices of Deficiency

The Commissioner must send a notice of deficiency to the taxpayer before he may assess, collect, or reduce to judgment most income tax liabilities. United States v. Zolla, 724 F.2d 808">724 F.2d 808, 724 F.2d 808">810 (9th Cir. 1984). If no notice is sent and the period of limitations has passed, then assessment generally is barred. See sec. 6501(a). However, the notice need not be received by the taxpayer, so long as the notice is mailed to the taxpayer's last known address. 724 F.2d 808">United States v. Zolla, supra.

A claim that an assessment is barred because no valid notice of deficiency was sent to the taxpayer is an affirmative defense under Rule 39. See Robinson v. Commissioner, 57 T.C. 735">57 T.C. 735 (1972). Such a claim must be set forth in the party's pleading, and a mere denial in a responsive pleading will not be sufficient to raise the issue. Rule 39. The taxpayer has the burden of proof with respect to such a matter. Rule 142(a); see Amesbury Apartments, Ltd. v. Commissioner, 95 T.C. 227">95 T.C. 227, 95 T.C. 227">240 (1990). Petitioner failed to raise a claim that the assessments against him for tax years 2000 and/or 2002 are barred.

1. 2000

Respondent did not present 2009 Tax Ct. Memo LEXIS 114">*129 either a copy of the notice of deficiency for 2000 or the certified mail list. By Order dated April 23, 2007, the Court remanded this case to respondent's Appeals Office to determine whether the assessment for tax year 2000 against petitioner was valid. Complying with that Order, respondent reviewed the TXMOD transcript. The transcript showed that process codes 75 and 90 were entered, which as stated supra p. 11, indicate the issuance of a notice of deficiency for tax year 2000 (process code 75) and an assessment of the deficiency for tax year 2000 by default (process code 90).

In the April 23, 2007, Order, the Court mandated that petitioner file a status report in which he was to state, inter alia, whether he had received a notice of deficiency for tax year 2000. In doing so, we stated:

petitioner has implied, if not tacitly admitted, that he received notices of deficiency for 2000 and 2002. However, in view of petitioner's patent unfamiliarity with tax practice and procedure, we shall require petitioner to unequivocally state whether he received, or whether he did not receive, (1) a notice of deficiency determining a deficiency and penalty in his Federal income tax for 2000 * * *.

Petitioner 2009 Tax Ct. Memo LEXIS 114">*130 responded to the Court's mandate stating: "Regarding tax year 2000, I do remember receiving some type of tax re-assessment from the IRS to which I immediately disputed". Thus, contrary to the Court's mandate, petitioner did not unequivocally state whether he did or did not receive a notice of deficiency determining a deficiency and penalty in his Federal income tax for 2000.

The Court's Order specifically stated:

Petitioner's failure to unequivocally state, in a response to this Order filed on or before August 15, 2007, whether he received or whether he did not receive, notices of deficiency for 2000 and 2002 shall be deemed to be an admission that he did receive notices of deficiency for those years.

Because petitioner failed to unequivocally state that he did not receive a notice of deficiency for 2000, petitioner is deemed to have admitted that he did receive a notice of deficiency for that tax year.

Petitioner has not alleged any irregularity in the information contained in the TXMOD transcript. And we have held that the Commissioner may rely on transcripts or other reports to satisfy the verification requirement imposed by section 6330(c)(1) that the requirements of any applicable 2009 Tax Ct. Memo LEXIS 114">*131 law or administrative procedure have been met. See Davis v. Commissioner, 115 T.C. 35">115 T.C. 35, 115 T.C. 35">41 (2000); Schroeder v. Commissioner, T.C. Memo. 2002-190; Mann v. Commissioner, T.C. Memo. 2002-48.

We are mindful of our holding in Butti v. Commissioner, T.C. Memo. 2008-82. In that case, the taxpayer stated that he had never received a notice of deficiency for the year at issue. Because the taxpayer affirmatively challenged the existence of the notice, we held that the Commissioner had to produce the notice of deficiency itself and could not rely on substitute methods of proof. The situation in the instant case is distinguishable from that in Butti. Petitioner was given multiple opportunities to challenge the existence of the notice of deficiency for tax year 2000, but in each instance petitioner failed to take advantage of the opportunity.

We thus find that the assessment against petitioner for tax year 2000 was proper and hold that petitioner may not challenge his underlying tax liability for that year.

2. 2002

Respondent issued a notice of deficiency on April 28, 2004, for tax year 2002, and petitioner acknowledged that he received it. Therefore, the assessment against petitioner for tax year 2009 Tax Ct. Memo LEXIS 114">*132 2002 was proper, and we hold that petitioner may not challenge his underlying tax liability for 2002.

On the basis of our conclusion that petitioner may not challenge the underlying tax liability for either 2000 or 2002, we review respondent's determination sustaining the filing of a lien to collect petitioner's unpaid Federal income taxes for 2000 and 2002 for abuse of discretion. Petitioner argues that respondent abused his discretion in several ways. First, petitioner argues that respondent abused his discretion by:

determining petitioner's tax returns 'frivolous,' without justification and without ascertaining the validity of petitioner's exempt income-tax-filing status (RE p. [sic] Nor has respondent made any effort to ascertain whether or not petitioner is exempt from income tax and in doing so has abused its discretion).

It is well established that arguing that an individual is exempt from income tax is frivolous and groundless. Accordingly, we do not find that respondent abused his discretion in rejecting petitioner's claim. See Homza v. Commissioner, T.C. Memo. 2008-174; George v. Commissioner, T.C. Memo. 2006-121; Wright v. Commissioner, T.C. Memo. 1990-232.

Next, 2009 Tax Ct. Memo LEXIS 114">*133 petitioner argues that respondent did not allow him to present evidence that would prove he was exempt from tax. Petitioner asserts that respondent refused to wait for the response from CalPERS regarding whether the payments to petitioner were tax exempt before issuing the notice of determination. We find this argument to be without merit. First, State entities such as CalPERS cannot determine whether a payment is subject to Federal income tax. See Morgan v. Commissioner, 309 U.S. 78">309 U.S. 78, 309 U.S. 78">80-81, 60 S. Ct. 424">60 S. Ct. 424, 84 L. Ed. 585">84 L. Ed. 585 (1940). Second, CalPERS sent petitioner its response on January 11, 2006, but when Settlement Officer Splinter asked petitioner on February 27, 2006, whether he had received the response, petitioner evasively replied that he was still waiting for it. Third, CalPERS's letter supports respondent's position, and not petitioner's position.

Finally, petitioner argues that respondent abused his discretion by not holding a face-to-face section 6330 hearing with petitioner. The record shows that petitioner was notified of his option to request a face-to-face hearing. However, there is no indication that petitioner ever requested a face-to-face conference before his section 6330 hearing occurred on December 2009 Tax Ct. Memo LEXIS 114">*134 22, 2005. Moreover, the record does not indicate that petitioner requested a face-to-face conference with respondent after this Court remanded the case to respondent's Appeals Office to consider the basis of the 2000 assessment against petitioner and the effect, if any, of petitioner's discharge in bankruptcy.

We have held repeatedly that because a hearing conducted under section 6330 is an informal proceeding instead of a formal adjudication, a face-to-face hearing is not mandatory. See Katz v. Commissioner, 115 T.C. 329">115 T.C. 329, 115 T.C. 329">337-338 (2000); 115 T.C. 35">Davis v. Commissioner, supra at 41. Accordingly, while a hearing may take the form of a face-to-face meeting, a proper section 6330 hearing may be conducted by telephone or by written correspondence. 115 T.C. 329">Katz v. Commissioner, supra; Connolly v. Commissioner, T.C. Memo. 2008-95; sec. 301.6330-1(d)(2), Q&A-D6, Proced. & Admin. Regs. We therefore do not find that the holding of the section 6330 hearings via telephone constituted an abuse of discretion.

D. Discharge in Bankruptcy

Petitioner argues that his tax liability was discharged by the U.S. Bankruptcy Court. We remanded the case to respondent's Appeals Office, in part, to determine whether petitioner's 2009 Tax Ct. Memo LEXIS 114">*135 tax liabilities were discharged. In the supplemental notice of determination respondent determined that petitioner's tax liabilities were not discharged in bankruptcy.

This Court has jurisdiction to determine, in the context of a lien proceeding, whether a taxpayer's tax debts were discharged in bankruptcy. See Washington v. Commissioner, 120 T.C. 114">120 T.C. 114, 120 T.C. 114">120-121 (2003). An individual debtor is not to be discharged in a bankruptcy proceeding from certain specified categories of debt as provided in 11 U.S.C. section 523(a) (2006):

(a) A discharge under section 727, 1141, 1228(a), 1228(b), or 1328(b) of this title does not discharge an individual debtor from any debt --

(1) for a tax or a customs duty --

(A) of the kind and for the periods specified in sections 707(a)(3) or 507(a)(8) of this title, whether or not a claim for such tax was filed or allowed;

Title 11 U.S.C. section 507(a)(8)(A)(i) refers to an income tax debt due and owing less than 3 years before the date of the filing of a bankruptcy petition as a priority tax debt. Petitioner's 2000 tax return was required to be filed by April 15, 2001. Therefore, under the terms of 11 U.S.C. section 523(a)(1)(A), the tax on that year's return 2009 Tax Ct. Memo LEXIS 114">*136 could only be discharged in a bankruptcy proceeding opened no earlier than April 15, 2004.

Petitioner's 2002 tax return was required to be filed by April 15, 2003. Therefore, the tax on that year's return could only be discharged in a bankruptcy proceeding opened no earlier than April 15, 2006.

Petitioner filed for bankruptcy on September 22, 2003. Accordingly, neither petitioner's 2000 nor his 2002 tax liabilities were discharged in bankruptcy.

E. Conclusion

We hold that respondent did not abuse his discretion in sustaining the filing of a lien to collect petitioner's unpaid Federal income taxes for 2000 and 2002.

We have considered all of petitioner's arguments, and to the extent not discussed herein, we find them to be groundless, irrelevant, and/or without merit and thus unworthy of being addressed.

To reflect the foregoing,

Decision will be entered for respondent.
