FINDINGS OF FACT
Petitioner resided in California when he filed his petition.
1. Petitioner's Addresses in 1986 Through 1988
Petitioner submitted two Forms W-2 in 1986 with his return. Petitioner's address shown on the Forms W-2 is 113 Beck, Harlingen, Texas 78550 (Harlingen I), and P.O. Box 160, McAllen, Texas 78501 (McAllen).
Petitioner filed his 1986 and 1987 income*792 tax returns with the Internal Revenue Service Center at Austin, Texas, on May 13, 1987, and July 11, 1988, respectively, showing his address as 601 North Reagan, San Benito, Texas 78586 (San Benito). Petitioner submitted three Forms W-2 with his 1987 return showing the San Benito address (two Forms W-2), and Rt. 3, Box 367-A Harlingen, Texas 78501 (Harlingen II).
2. Petitioner's Harlingen and Plano Addresses in January Through October 1989
On January 24, 1989, petitioner executed a Power of Attorney and Declaration of Representation (Form 2848) appointing Joseph Fletcher (Fletcher) and Elizabeth M. Dietz (Dietz) attorneys in fact to represent him for 1985, 1986, and 1987, and directing that copies of all notices and other written communication be sent to Fletcher. The Form 2848 shows P.O. Box 2894, Harlingen, Texas 78551 (Harlingen III).
On July 27, 1989, petitioner filed his 1988 income tax return with the Internal Revenue Service Center at Austin, Texas. Petitioner's address shown on this return is 2301 Pebble Vale, Apt. 122, Plano, Texas 75075 (the Plano address). The 1988 return was petitioner's most recently filed return when respondent mailed the notice of deficiency*793 for 1986. The 1988 Forms W-2, attached to the 1988 return, showed the Harlingen II and III addresses.
On August 21, 1989, respondent's agent requested that petitioner and his new wife sign an additional Form 2848 for 1987. Petitioner executed a new Form 2848 on September 11, 1989, reappointing Fletcher and Dietz as attorneys in fact for 1985, 1986, and 1987, and directing that copies of all written communications be sent to Fletcher, Strait, Riddle & Co. Petitioner used the Harlingen III address on this Form 2848. On October 3, 1989, Fletcher executed Form 872, Consent to Extend the Time to Assess Tax, extending the period for assessment of tax for 1986 to September 30, 1990. The address on this form is the Plano address.
3. Respondent's Handling of Petitioner's 1986 and 1987 Years
On October 26, 1989, respondent prepared 30-day letters for 1986 and 1987. Both 30-day letters show the Plano address as petitioner's address. On October 30, 1989, Fletcher received a copy of the 30-day letter for 1987. The 30-day letter for 1986 was returned to respondent as undeliverable. Respondent did not mail additional copies of the 30-day letter for 1986.
Originally, respondent's*794 case files for petitioner's 1986 and 1987 years were kept together because the audits were performed together. Respondent's agent wrote on the bottom of an Internal Revenue Service (IRS) special handling notice: "Please keep the 1986 & 1987 case files together. The same issue applies on each year." However, the 1986 case file was sent from the examining agent's group to 30-day review on October 13, 1989, without the 1987 file. The 1987 case file was not with the 1986 file when the notice of deficiency was prepared. Therefore, sometime before the end of October 1989, the 1986 and 1987 case files were separated.
A copy of an examination report for 1986 was returned to respondent undeliverable at a date not indicated in the record.
4. December 1989: San Felipe Address
Petitioner leased apartment No. 1807 at 7920 San Felipe Boulevard, Austin, Texas 78729 (the San Felipe address), on or about November 24, 1989.
On December 8, 1989, petitioner executed a third Form 2848, designating Elton Lipnick as an additional representative for 1987. The address shown for petitioner on this form is 7920 San Felipe, No. 1807, Austin, Texas 78729.
On December 22, 1989, petitioner filed*795 a protest for 1987 with respondent's Austin, Texas, office. The address shown on the protest letter is the San Felipe address.
5. The Notice of Deficiency
To determine petitioner's last known address as of January 23, 1990, respondent examined records and the following four different addresses: (1) P.O. Box 2894, Harlingen, Texas 78551; (2) 601 North Reagan, San Benito, Texas 78586; (3) 2301 Pebble Vale, Apt. 122, Plano, Texas 75075, and (4) 7920 San Felipe 2106, 1Austin, Texas 78729. Respondent mailed a deficiency notice for 1986 to petitioner at the Plano address on January 23, 1990. It was returned to respondent on February 27, 1990, in an envelope stamped "Address Correction Requested". It was also marked "Return to Sender Unclaimed" with indications of two attempted deliveries. On March 12, 1990, respondent's agent performed a computer search which indicated that petitioner's address was the Plano address.
Petitioner filed his petition for 1986 on February 14, 1991.
OPINION
*796 1. Background
To maintain an action in this Court, there must be a valid notice of deficiency and a timely filed petition.
*797 2. Last Known Address
The sole issue for decision is whether respondent properly mailed the notice of deficiency to petitioner's last known address within the meaning of section 6212(b)(1). Section 6212(a) authorizes the Secretary, upon the determination of a deficiency in income tax, to issue a notice of deficiency by certified or registered mail to the taxpayer. A notice of deficiency is valid, regardless of actual receipt by the taxpayer, if mailed to the taxpayer at his last known address. Sec. 6212(b).
The phrase "last known address" is not defined by the Code or regulations. A taxpayer's last known address generally is the address to which, in light of the surrounding facts and circumstances, respondent reasonably believed the taxpayer wished the notice of deficiency to be sent.
Petitioner has the burden of proving that the notice of deficiency was not sent to his last known address.
Respondent mailed the notice of deficiency to the Plano address used on petitioner's 1988 return, his most recently filed return. Ordinarily, the Commissioner may treat the address on the taxpayer's most recently filed return as the last known address, absent "clear and concise notification" that a new address be used by the Commissioner for tax matters.
Petitioner did not clearly communicate that he wanted all tax communications to be sent to the San Felipe rather than the Plano address. After filing his 1988 return using the Plano address, petitioner filed another document with the Plano address, and a Form 2848 and protest for 1987, both with the San Felipe address. He did not state to respondent that the Plano address should no longer be used, or that he wanted all further communication addressed to San Felipe. The filing of the Form 2848 and protest letter for 1987 is not a clear and concise notice to respondent of a change of address, where petitioner has used numerous other addresses in the recent past. See
However, as noted by the Court of Appeals for the Ninth Circuit, the circuit to which this case is appealable, we must decide whether respondent should have inquired further. See
3. Return of Letters to Respondent
Once respondent becomes aware of an address other than the one on a taxpayer's most recently filed return, respondent must exercise reasonable care and due diligence in ascertaining the correct address.
Respondent claims not to have known that the 30-day letter and examination report were returned before the notice of deficiency was sent. *801 Petitioner argues that respondent was on notice that his address was no longer the Plano address because his 30-day letter for 1986 was returned to respondent undeliverable. Petitioner points to a letter from respondent dated December 19, 1990, which states: "The 30 day letter was dated October 26, 1989, but no envelope was attached showing what date it was returned." Respondent's grounds for arguing that the 30-day letter was not returned is that respondent's file did not include a copy of the envelope in which the returned 30-day letter had been sent. We do not view the absence of the envelope in respondent's file to be dispositive as to this fact in light of respondent's letter which referred to a returned 30-day letter.
Petitioner points to another letter from respondent about 1986 which states: "The examination report we sent to you was returned to us as undeliverable by the postal service." This letter establishes that the examination report for 1986 was returned to respondent. Respondent presumably has records showing when it was returned. Respondent did not produce any evidence of when the examination report was mailed, to what address it was mailed, or when it was returned. *802 Under the adverse inference rule,
This Court has stated:
The rule is well established that the failure of a party to introduce evidence within his possession and which, if true, would be favorable to him, gives rise to the presumption that if produced it would be unfavorable. This is especially true where, as here, the party failing to produce the evidence has the burden of proof or the other party to the proceeding has established a prima facie case. [Citations omitted.]
In
once respondent becomes aware of a change in address, he must exercise reasonable care and diligence in ascertaining and mailing the notice of deficiency to the correct address. Whether respondent has properly discharged this obligation is a question of fact.
Whether respondent has exercised reasonable care and diligence must be decided in light of all the facts and circumstances.
Here, respondent received as undeliverable the 30-day letter for 1986 addressed to the Plano address and an examination report for 1986. Respondent made a last known address inquiry and considered the San Felipe, Harlingen, San Benito, and Plano addresses. The record does not indicate how respondent evaluated the four addresses or what steps respondent took to determine petitioner's correct address. Respondent sent the notice of deficiency to the Plano address which respondent had previously used unsuccessfully. There is no evidence of any other attempt by respondent to determine the correct address.
