MEMORANDUM FINDINGS OF FACT AND OPINION
LARO, Judge: Petitioners petitioned the Court to redetermine a $ 29,771 deficiency in their 1997 Federal income tax, a $ 4,115 addition thereto under section 6651(a)(1), and a $ 4,517 accuracy-related penalty under section 6662(a). We decide the only issue that petitioners raised in their petition and discussed in their brief; namely, whether the applicable 3-year period of limitations under section 6501(a) has run as to their 1997 taxable year. We hold it has not. Unless otherwise noted, section references are to the applicable versions of the Internal Revenue Code.
FINDINGS OF FACT
Some facts were stipulated. The stipulated facts and the accompanying exhibits are incorporated herein by this reference. We find the stipulated facts accordingly. Petitioners resided in Montgomery, Texas, when their petition was filed.
Petitioners filed with respondent a 1997 Form 1040, U.S. Individual Income Tax Return, using the filing status of "Married filing joint return" and reporting their "total tax" and "total [tax] payments" for the year as $ 13,340 and $ 16,327, respectively. The return consisted of seven single-sided pages. The information that petitioners furnished in the signature block on page 2 of the Form 1040 (i. e., signatures, date of signatures, and occupations) was all written by hand, as were two "X" s that were placed in the "No" blocks to questions requiring the checking of a "Yes" or "No" box. All other information petitioners reported on their 1997 return was typed. Petitioners reported on the 1997 return that they had each signed the return on April 15, 1998.
Walter R. Huff (Mr. Huff) testified at trial that he mailed petitioners' 1997 return to respondent between 10: 30 p. m. and 10: 45 p. m. on April 15, 1998, in an envelope that also contained petitioners' completed 1997 Form 4868, Application for Automatic Extension of Time to File U.S. Individual Income Tax Return. Mr. Huff testified that he mailed this envelope by placing it in a post office box at a post office near his home in Chino Hills, California. Respondent's records indicate that his department in Fresno, California, received petitioners' 1997 tax return on April 23, 1999, and respondent filed that return as of that date. Respondent mailed the subject notice of deficiency to petitioners on March 7, 2002.
Petitioners' 1997 Form 4868 is a one-page document on which petitioners listed their names, address, Social Security numbers, and numeric answers to requested information concerning their 1997 Federal income tax. The requested information was "4 Total tax liability for 1997", "5 Total 1997 payments", and "6 Balance. Subtract 5 from 4". Petitioners answered that their total tax liability for 1997 was "15,800", that their total 1997 tax payments equaled "15,800+", and that their balance was zero. All of the information that petitioners listed on their 1997 Form 4868 was written by hand. Petitioners requested through this Form 4868 an extension of time until August 15, 1998, to file their 1997 Federal income tax return. Respondent filed this Form 4868 as of April 15, 1998.
During the subject year, Mr. Huff was an attorney specializing in personal injury work in the State of California. 1 He practiced law through his sole proprietorship. His practice during 1997 paid wages of $ 92,000 to his wife and withheld from those wages Federal income taxes of $ 16,327. These withholdings were the only Federal income tax payments petitioners made during 1997.
Respondent's records show that petitioners filed their 1991 Federal income tax return untimely on June 5, 1994, that they filed their 1992 Federal income tax return untimely on October 20, 1993, that they filed their 1993 Federal income tax return untimely on February 9, 1995, that they filed their 1994 Federal income tax return untimely on October 15, 1995, that they filed their 1995 Federal income tax return untimely on June 11, 1997, that they filed their 1999 Federal income tax return untimely on September 13, 2001, and that they filed their 2000 Federal income tax return untimely on September 17, 2001. 2 Respondent's records show that petitioners filed their 1996 Federal income tax return timely on July 31, 1997, after requesting and receiving an extension of the due date for the return to August 15, 1997, and that petitioners filed their 1998 Federal income tax return timely on April 15, 1999.
OPINION
Petitioners argue that the applicable period of limitations under section 6501(a) has run. We disagree. The Commissioner generally must assess tax against individual taxpayers such as petitioners within 3 years of the later of the due date or the filing date of their return. Sec. 6501(a) and (b)(1); Mecom v. Commissioner, 101 T.C. 374, 382 (1993), affd. without published opinion 40 F.3d 385 (5th Cir. 1994). On the basis of the credible evidence in the record, we find as facts that petitioners filed their 1997 return with respondent on April 23, 1999, and that respondent issued to them the subject notice of deficiency within 3 years after that date.
Mr. Huff testified that he mailed petitioners' 1997 return to respondent on April 15, 1998. We find that testimony to be uncorroborated and incredible. 3We need not and do not rely upon that testimony for the purpose of reaching our decision herein. See Casperone v. Landmark Oil & Gas Corp., 819 F.2d 112, 115 (5th Cir. 1987); Ruark v. Commissioner, 449 F.2d 311, 312 (9th Cir. 1971), affg. per curiam T.C. Memo. 1969-48; Neonatology Associates, P.A. v. Commissioner, 115 T.C. 43, 84 (2000), affd. 299 F.3d 221 (3d Cir. 2002). In fact, on the basis of our perception of Mr. Huff as he testified, and our evaluation of his overall testimony in the light of the record as a whole, we reject petitioners' argument on brief that Mr. Huff's testimony constitutes "credible evidence" sufficient to shift the burden of proof to respondent under section 7491(a).
Mr. Huff during his testimony had a selective loss of memory; for example, he could vividly recall specific facts that supported his case but generally had no recollection as to many other facts which could have been detrimental to his case (e. g., whether he filed timely his 1997 State income tax return, whether he filed timely his 1991 through 1993 Federal income tax returns). He also testified that he prepared petitioners' 1997 Form 4868 immediately after he had finished preparing their 1997 Form 1040 and that he prepared the former document because he was concerned that the latter document would not be postmarked timely. In that the 1997 Form 1040 reports for 1997 that petitioners' total tax and total tax payments equal $ 13,340 and $ 16,327, respectively, petitioners' reporting on their 1997 Form 4868 that their total tax and total tax payments for that year equaled $ 15,800 and "$ 15,800+", respectively, indicates that Mr. Huff did not readily know when he prepared the 1997 Form 4868 the precise amount of either petitioners' total tax or their tax payments.
The fact that Mr. Huff testified that he mailed the 1997 Form 1040 and the 1997 Form 4868 to respondent in the same envelope also undercuts his testimony that he filed the Form 4868 simply out of concern that the Form 1040 would not be postmarked timely. A request for an automatic extension of time to file a tax return must be filed before the unextended due date of that return. See sec. 1.6081-4(a)(3), Income Tax Regs. We are hard pressed to understand how an attorney such as Mr. Huff could have expected or perceived that two documents mailed to respondent in the same envelope would be treated by respondent as filed on different dates. We also are hard pressed to understand why, if Mr. Huff had prepared the 1997 Form 4868 immediately after he completed the 1997 Form 1040, as he testified, petitioners typed almost all of the information on the 1997 Form 1040 but hand wrote the minimal information reported on the 1997 Form 4868. We also note that although Mr. Huff indicated during his testimony that petitioner Lucy C. Huff could corroborate his assertion that he had filed their 1997 tax return late on the evening of April 15, 1998, he neither called her to testify under oath as to this matter nor offered a valid explanation as to why she was unavailable to testify. We can only assume that petitioner Lucy C. Huff's testimony as to this matter would have been unfavorable to petitioners' case. See, e.g., Wichita Terminal Elevator Co. v. Commissioner, 6 T.C. 1158, 1165 (1946), affd. 162 F.2d 513 (10th Cir. 1947).
The thrust of petitioners' argument is that they must prevail because respondent has not produced the envelope in which respondent received their 1997 tax return. Petitioners note that respondent acknowledges that respondent lost or destroyed this envelope and that respondent's witness, an employee of respondent, testified that respondent attaches to all late filed returns the envelope in which the return was received. Petitioners assert that the envelope, by its postmark, would have confirmed Mr. Huff's testimony that he mailed petitioners' 1997 tax return to respondent on April 15, 1998, that section 7502 would then treat the postmark date as the date of filing, 4 and that the period of limitations under section 6501 would then be shown to have run before respondent issued the subject notice of deficiency to them. As petitioners see it, section 7502 "imparts upon respondent the burden of preserving and producing the envelope since * * * the envelope is the sole exclusive evidence on the issue of timely mailing/ timely filing."
We disagree with petitioners that respondent's failure to produce the envelope in which respondent received their 1997 tax return means as a matter of law that we must decide this case for them. In order to reach their desired end, petitioners rely erroneously on Lewis v. United States, 144 F.3d 1220 (9th Cir. 1998), and Anderson v. United States, 966 F.2d 487 (9th Cir. 1992). 5 In each of those cases, the taxpayer produced credible evidence of the date of mailing of the document in question. Here, by contrast, we do not find that Mr. Huff testified credibly that he mailed petitioners' 1997 Form 1040 timely.
Because respondent has failed to produce the envelope containing petitioners' return, we decide this case as if the postmark were missing; thus, petitioners may rely upon extrinsic evidence to prove that the postmark, if present, would have been timely. See Jacobson v. Commissioner, 73 T.C. 610, 615, 616 (1979). The only evidence petitioners introduced as to this matter was Mr. Huff's testimony, which we do not find to be credible. 6 We hold for respondent.
We have considered all arguments made by the parties and, to the extent not discussed herein, have rejected those arguments as meritless.
Decision will be entered for respondent.
