MEMORANDUM FINDINGS OF FACT AND OPINION

GERBER, Chief Judge: Respondent determined a deficiency of $ 5,179 in petitioner's Federal income tax for 2001. After concessions by respondent, the sole issue for consideration is whether petitioner qualifies for the earned income tax credit under section 32(a). ¹

             FINDINGS OF FACT

Petitioner resided in Miami, Florida, at the time that he filed his petition. On July 23, 1997, petitioner married Eunice Pereyra. Petitioner and his wife had two children, a daughter born on May 14, 1998, and a son born on January 16, 2000. Petitioner's daughter and son lived with petitioner at all times during 2001.

2004 Tax Ct. Memo LEXIS 147">*148 Petitioner's wife did not have legal resident status in the United States and did not possess a Social Security number. During 2001, petitioner's wife left the United States for Mexico.

Petitioner and his wife did not file a joint Federal income tax return for 2001. Petitioner filed electronically a Form 1040, U.S. Individual Income Tax Return, for 2001. On his Form 1040, petitioner claimed "head of household" filing status.

Petitioner remained married throughout 2001 and through the trial of this case in December 2003. Petitioner's wife did not return to the United States.

In the notice of deficiency, respondent determined that petitioner's filing status was "married filing separate" and disallowed petitioner's dependent exemptions, earned income credit, and child tax credit. Respondent now concedes that petitioner is entitled to claim "head of household" filing status (and the increased standard deduction available for that filing status), his claimed dependent exemptions, and the child tax credit.

                OPINION

Section 32(a)allows a refundable earned income credit in amounts specified and under conditions specified in that section. 2004 Tax Ct. Memo LEXIS 147">*149 One of the conditions is that, in the case of an individual who is married, a joint return with the individual's spouse must be filed for the year for which the credit is claimed. Sec. 32(d); sec. 1.32-2(b)(2), Income Tax Regs.

For purposes of section 32(a), a taxpayer's marital status is determined under section 7703. Section 7703(b)provides in pertinent part:

     SEC. 7703(b). Certain Married Individuals Living Apart. --

   For purposes of those provisions of this title which refer to

   this subsection, if --

        (1) an individual who is married (within the meaning

     of subsection (a)) and who files a separate return

     maintains as his home a household which constitutes for

     more than one-half of the taxable year the principal place

     of abode of a child (within the meaning of section

     151(c)(3)) with respect to whom such individual is entitled

     to a deduction for the taxable year under section 151 (or

     would be so entitled but for paragraph (2) or (4) of

     section 152(e)),

        (2) such individual2004 Tax Ct. Memo LEXIS 147">*150 furnishes over one-half of the

     cost of maintaining such household during the taxable year,

     and

        (3) during the last 6 months of the taxable year, such

     individual's spouse is not a member of such household, such

     individual shall not be considered as married.

Petitioner has made vague and inconsistent assertions as to when his wife left his household in 2001. He testified:

     MR. DIAZ: I believe she left between June and July of 2001.

   2001, yes.

     THE COURT: Has she ever returned?

     MR. DIAZ: Never.

           *   *   *   *   *   *   *

     MR. DIAZ: * * * But she was not living with me during the

   whole period of 2001, because, when I moved, it was about six

   months that she was not even living with me. She moved -- she

   moved -- she left the apartment with her mother that came from

   Mexico and she decided to leave.

Only in his answering brief does petitioner state categorically that his wife left in June, asserting: "The commissioner makes emphasis in the date2004 Tax Ct. Memo LEXIS 147">*151 in which my wife left the country to which for me is not much of importance." The assertion in petitioner's brief, however, cannot be treated as evidence. Rule 143(b). The date on which petitioner's wife left his household is not only important; it is determinative. If petitioner's wife left in July rather than June, he is not entitled to the earned income tax credit. See Becker v. Commissioner, T.C. Memo. 1995-177. In the absence of reliable evidence that she left prior to July 2001, petitioner is not entitled to the earned income tax credit under section 32(a).

It appears from the arguments in his briefs that petitioner may be confused by respondent's concession that, for purposes of "head of household" status, petitioner may be treated as an unmarried person. For purposes of section 2(b), dealing with "head of household" status, the taxpayer may be considered not married at the close of the year if "at any time during the taxable year his spouse is a nonresident alien". Sec. 2(b)(2)(C). The definition in that section, however, has not been extended to other situations where marital status is determined under section 7703 (formerly section 143). See Kravetz v. Commissioner, T.C. Memo. 1985-496,2004 Tax Ct. Memo LEXIS 147">*152 affd. without published opinion (D.C. Cir., Oct. 17, 1986). The specifically applicable statutory definition cannot be disregarded even though petitioner argues persuasively that he was disabled from filing a joint return because of his wife's inability to stay in the United States legally or to obtain a Social Security number. Cf. Peppiatt v. Commissioner, 69 T.C. 848">69 T.C. 848, 69 T.C. 848">853-854 (1978).

In order to reflect respondent's concessions,

Decision will be entered under Rule 155.
