Zoila appeals a district court judgment in favor of the government in its action to reduce to judgment Zolla’s federal income tax liabilities for 1968 and 1969.
Neither the government nor Zoila introduced direct evidence of Zolla’s income and deductions for the years in question. The government relied upon the presumption of correctness that attaches to the IRS’s determination of a tax deficiency.
See Rockwell v. Commissioner,
A. The Deficiency Was Not Arbitrary
This court has held that no presumption of correctness attaches to deficiency determinations in which the IRS charges a taxpayer with additional income but provides no factual showing that the taxpayer actually received the income in question. To give effect to the presumption in such circumstances would impose on the taxpayer the difficult task of proving a negative.
See Weimerskirch v. Commissioner,
The remainder of the 1968 deficiency was based on the inclusion of income shown in an unfiled 1968 tax return obtained from Zolla’s CPA. The inclusion of those amounts, shown in Zolla’s own records, did not lack a factual basis under Weimerskirch.
B. The Government Proved That Notices Had Been Mailed
The IRS, by established routine, had destroyed all copies of the notices of deficiency and demands for payment that had been mailed to Zoila. The government submitted postal form 3877 certifying that the notices of deficiency had been mailed and an IRS form certifying that the taxes and the section 6651(a)(3) 1 failure-to-pay penalties had been assessed. Zoila offered no contrary evidence.
We adopt the view of the Eighth Circuit and the Tax Court that these official certificates are highly probative, and are sufficient, in the absence of contrary evidence, to establish that the notices and assessments were properly made.
See United States v. Ahrens,
C. The Notices Were Mailed to the Taxpayer’s Last Known Address
The IRS must send a notice of deficiency before it may assess, collect, or reduce to judgment most income tax liabilities. § 6213(a). The notice is valid even if not received by the taxpayer, if it is mailed to the taxpayer’s last known address.

See
§ 6212(b)(1);
Cool Fuel, Inc. v. Connett,
A taxpayer’s last known address is that on his most recent return, unless the taxpayer communicates to the IRS “clear and concise” notice of a change of address.
See McPartlin v. Commissioner,
It is undisputed that the North Bedford Street address to which the notice of deficiency was mailed was the address on Zolla’s most recent return. 3 Zoila filed a 1970 return in October 1971, showing that address. Zoila did not file a 1971 return. The notice of deficiency was mailed in June 1973. Zoila filed a 1972 return in 1974, showing a new address.
Zoila argues that the IRS had notice of a change of address because, before the notices of deficiency were mailed, an agent in the collection division of the same district office discovered a more recent address (La Peer Street) while attempting to collect an unrelated tax liability. The collection agent filed a notice of tax lien showing the La Peer Street address.
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.
Kuebler
v.
Commissioner,
Zoila also contends that the IRS had notice of a change in address because the La Peer Street address was in one of the IRS computer files. The argument is not supported by the record. Contrary to Zolla’s assertion, the collection agent did not state that he discovered the La Peer Street address from the computer files. Furthermore, the IRS’s answers to Zolla’s interrogatories stated that North Bedford Street was the most recent address in the district, regional, and national IRS computer files at the time the notices were mailed. Zoila did not controvert this sworn statement. 5
Zoila does not allege that he made any attempt to advise any IRS office or the auditing agents of his numerous changes of address. Nor did Zoila effectively controvert the sworn statement that the address to which the notices were sent was the most recent shown in the IRS computer files. On this record, the address on Zolla’s most recent return was his last known address as a matter of law, and the district court did not err in entering summary judgment for the government.
Affirmed.
Notes
. All statutory references are to the Internal Revenue Code of 1954, Title 26 of the United States Code.
. The Government does not contest Zolla’s allegation that he did not actually receive the notices.
. Zoila notes that the district court’s findings of fact state that the notices were sent to North Beverly Drive. It is clear from the context that this was merely a transcribing error. The certificates clearly show that the notices were mailed to North Bedford Street. In any case, this court can affirm on the basis that the record clearly shows that the notices were mailed to North Bedford Street.
See Shipley v. United States,
. Unless, of course, the taxpayer actually receives the notice promptly.
See Clodfelter v. Commissioner,
. Zoila contends that the district court erred in relying upon this evidence because it was contained in answers to interrogatories that could not properly be considered on summary judgment. He argues that Fed.R.Civ.P. 56(c), (e) permits the consideration of answers to interrogatories only if they are admissible and made upon personal knowledge.
