Thе Commissioner appeals from the Tax Court’s order dismissing the Kings’ petition for lack of jurisdiction. The Tax Court held that the Commissioner failed to exercise reasonable diligence to ascertain the Kings’ last known address and that therefore the notice of deficiency mailed to the Kings’ former address was invalid. We have jurisdiction pursuant to 26 U.S.C. § 7482 (1982 & Supp. IV 1986) 1 and we affirm.
FACTS AND PROCEEDINGS BELOW
The essential facts are undisputed and are set forth in the Tax Court’s opinion.
See King v. Commissioner,
Taxpayers filed Federal income tax returns for 1978 and 1979 with the Internal Revenue Service Center in Austin, Texas. At that time, taxpayers resided at 7140 Mossvine Drive in Dallas. When the Dallas District Director’s Office selected taxpayers’ 1978 and 1979 returns for review, taxpayers filed two powers of attorney with the Dallas office listing the Mossvine address.
In October 1980, taxpayers moved to 17223 Club Hill Drive in Dallas. However, taxpayers subsequently filed with the Dallas office an additional power of attorney and a Form 4549 erroneously listing their Mossvine address. Taxpayers first used their Club Hill address on correspondence with the IRS in April 1981, when they requested an extension of time to file their 1980 return. On June 15, 1981, taxpayers filed their 1980 return using their Club Hill address. Both the request for extension and the return were filed with the Austin Service Center.
On August 17, 1981, the Dallas office sent taxpayers a 30-day letter at the Mos-svine address, which was forwarded to the Club Hill address. On September 17, 1981, taxpayers’ attorney (Billings) responded by filing a verified protest letter which erroneously listed the Mossvine address. Several weeks later, Mr. King’s secretary called Billings to inform him that the Mossvine address was no longer correct, but Billings did not inform the IRS of the change.
In December 1981, the Austin Service Center sent two Statements of Adjustment covering the 1978 and 1979 tax years to taxpayers at the Club Hill address.
On February 19, 1982, the Dallas office mailed a notice of deficiency to the Moss- *678 vine address, with copies to taxpayers’ accountant and attorney. 2 Thе notice was returned as undeliverable in March, 1982. When the notice was returned, appeals officer Dwyer reviewed the administrative file to determine if the notice had been sent to the correct address, but he concluded that it had been and took no further action. At no time did Dwyer request a cоmputer search of the records of the Austin Service Center.
In July 1982, the IRS assessed the deficiency and began collection procedures. Taxpayers sought to enjoin the collection by filing suit in federal district court. That suit was eventually dismissed without prejudice, and taxpayers filed the instant petition in the Tax Court on December 4, 1984. Both parties moved for dismissal. On April 23, 1987, the Tax Court issued an opinion concluding that “the notice of deficiency was not sent to [taxpayers’] last known address and it is therefore invalid.”
King v. Commissioner,
ISSUE
Did the Tax Court err in finding that the Commissioner did not mail the notice of deficiency to the taxpayers’ last known address?
STANDARD OF REVIEW
We consider first the question of what standard of review we should apply. In
Cool Fuel, Inc. v. Connett,
The Commissioner argues that
de novo
review is appropriate, citing
Scar v. Commissioner,
whether a form letter that asserts that a deficiency has been determined, which letter and its attachments make it patently obvious that no determination has in fact been made, satisfies the statutory mandate.
Scar,
Under
McConney,
“the key to the resolution of this question is the nature of the inquiry that is required.”
We find further guidance in
McConney
’s discussion of two tax cases:
Helvering v. Tex-Penn Oil Co.,
The nontechnical nature of the statutory standard, the close relationship of it to the data of practical human experience, and the multiplicity of relevant factual elements, with their various combinations, creating the necessity of ascribing the proper forcе to each, confirm us in our conclusion that the primary weight in this area must be given to the conclusions of the trier of fact.
Here, the “last known address” inquiry requires an examination of the totality of the circumstances and a balancing of many relevant factual elements, factors which indicate that the inquiry is “essentially factual.” We therefore conclude that clearly erroneous review is appropriate.
3
Our conclusion is in accord with the two other circuits which have specifically addressed this issue.
See McPartlin v. Commissioner,
DISCUSSION
The IRS must give notice to the taxpayer before it may assess or collect any deficiency. I.R.C. § 6213(a). A notice of deficiency is valid, even if it is not received by the taxpayer, if it is mailed to the taxpayer’s “last known address.” I.R.C. § 6212(b)(1);
see Wallin v. Commissioner,
The Tax Court has established, and this court has adopted, the following frequently cited rule:
[Wjhile the Commissioner is bound to exercise reasonable diligence in. ascertaining the taxpayer’s correct address, he is entitled to treat the address appearing on a taxpayer’s return as the last known in the absence of clear and concise notification from the taxpayer directing the Commissioner to use a different address.
Alta Sierra Vista, Inc. v. Commissioner,
This circuit has consistently held that “a subsequеntly filed tax return with a new address does give the IRS notice” of a change of address.
Wallin,
The application of ordinary business principles to the tax business of the government would seem to require the Commissioner to avail himself of the facilities of his business organization in the performance of his duty to mail the notice of deficiency. [quoting Welch v. Schweitzer,106 F.2d 885 , 887 (9th Cir.1939) ]
Id. at 312-13.
Here, it is likewise clear that the IRS had knowledge of the taxpayers’ new address. The taxpayers had filed a subsequent return bearing their new address, and the IRS had sent collection notices regarding the tax years at issue to that address. Cool Fuel holds that this is sufficient to impute knowledge of the new address to the audit division. Id.
Zoila is not to the contrary. In Zoila, it was undisputed that the address to which the notice of deficiency was mailed was the address shown on the taxpayer’s most recent return. The taxpayer argued, however, that the collection division had discovered his new address while attempting to collect an unrelated tax liability. We rejected this argument, saying:
We adopt the view of the Tax Court that such information gained by a collector should not necessarily be imputed to the audit agents who mailed the notices of deficiency.... If we required agents mailing notices of deficiency to take into account address information acquired by agents in different divisions in the course of unrelated investigations, the IRS could ensure that notices were validly addressed only be systematically recording in a central file all address information acquired in any fashion. We decline to require the IRS to do that.
We recognized in
Zoila
that “the IRS must have clear guidance as to what information it must examine in determining a taxpayer’s last known address.”
The Commissioner, however, argues that the protest letter filed by Billings, which certified that the Mossvine address was correct, constituted clear and concise notice and that the IRS was entitled to rely on it. We think this argument misses the point, since Officer Dwyer never checked to see if the address matched that
*681
on the taxpayer’s most recent return. Had he done so, he would have discovered the discrepancy and further inquiry could have bеen made. In any case, we believe that the protest letter did not constitute “clear and concise” notice as a matter of law. Correspondence bearing an address different from that on the most recent return does not, by itself, constitute clear and concise notice.
See, e.g., Tadros v. Commissioner,
The Tax Court followed a somewhat different analysis. It relied on the following language from Cool Fuel, which was appended to our discussion of Welch v. Schweitzer:
This is particulаrly so where, as here, the return of the notice of deficiency as undeliverable put the IRS on notice that Cool Fuel had moved. In light of this, the audit division had a duty to exercise reasonable diligence in ascertaining the correct address. Had the audit division done so, it would have realized that the Parаmount address was the last known address and could have effectuated notice. Failure of the IRS to do this is a violation of the statutory notice procedure.
However, although we believe the Tax Court erred in its analysis of
Cool Fuel,
we may nonetheless affirm on any basis clearly supported by the record.
Zolla,
AFFIRMED.
Notes
. Although the operative facts occurred in Texas, venue is proper in this court because the taxpayers resided in Arizona at the time their рetition was filed. See 26 U.S.C. § 7482(b)(1).
. Billings testified that he received a copy of the notice of deficiency, but that he took no action and did not contact taxpayers because they had since retained another attorney. Taxpayers’ accountant, Kreatschmann, testified that he did not receive the copy mailed to him.
.
Wallin v. Commissioner,
. An improperly addressed notice may also be valid if it is actually received by the taxpayer in sufficient time to make a timely petition, or if the taxpayer otherwise learns of the notice and acknowledges it by making a timely petition.
See Mulvania v. Commissioner,
.We note that the Tax Court and the majority of the courts of appeals have declined to аdopt a bright-line rule, although these courts nonetheless emphasize that a subsequent return is an important factor in determining a taxpayer’s last known address.
See, e.g., McPartlin,
.
Compare Tadros v. Commissioner,
. This is especially true today, when tax return information is systematically recorded on computer files and a computer search may be performed with ease.
See Wallin
at 677 & n. 4. The Commissioner disputes that this was true during the time involved here; however, since the notice of deficiency here was prepared in December 1981 and mailed in February 1982, a four-to-six-week delay would still hаve resulted in timely notice before the statute of limitations expired in April 1982.
See Crum,
. Our reading of
Cool Fuel
is consistent with our subsequent decision in
Wallin.
There, we noted that four letters sent to the taxpayer had been returned as undeliverable, putting the IRS on notice that the taxpayer had moved.
