Example. A taxpayer failed to file an income tax return and pay the taxes owed. After the taxes were assessed and the taxpayer was notified of the balance due, a revenue officer filed a notice of federal tax lien and then served a notice of levy on the taxpayer's bank. The notices of lien and levy contained the taxpayer's name, social security number, amount of outstanding liability, and the tax period and type of tax involved. The taxpayer's assets were levied to satisfy the tax debt, but it was determined that, prior to the levy, the revenue officer failed to issue the taxpayer a notice of intent to levy, as required by section 6331, and a notice of right to hearing before the levy, as required by section 6330. The disclosure of the taxpayer's return information in the notice of levy is authorized by section 6103(k)(6) despite the revenue officer's failure to issue the notice of intent to levy or the notice of right to hearing. The ultimate validity of the underlying levy is irrelevant to the issue of whether the disclosure was authorized by section 6103(k)(6).
Example 1. A revenue agent is conducting an examination of a taxpayer. The taxpayer has been very cooperative and has supplied copies of invoices as requested. Some of the taxpayer's invoices show purchases that seem excessive in comparison to the size of the taxpayer's business. The revenue agent contacts the taxpayer's suppliers for the purpose of corroborating the invoices the taxpayer provided. In contacting the suppliers, the revenue agent discloses the taxpayer's name, the dates of purchase, and the type of merchandise at issue. These disclosures are permissible under section 6103(k)(6) because, under the facts and circumstances known to the revenue agent at the time of the disclosures, the disclosures were necessary to obtain information (corroboration of invoices) not otherwise reasonably available because suppliers would be the only source available for corroboration of this information.
Example 2. A revenue agent is conducting an examination of a taxpayer. The revenue agent asks the taxpayer for business records to document the deduction of the cost of goods sold shown on Schedule C of the taxpayer's return. The taxpayer will not provide the business records to the revenue agent, who contacts a third party witness for verification of the amount on the Schedule C. In the course of the contact, the revenue agent shows the Schedule C to the third party witness. This disclosure is not authorized under section 6103(k)(6). Section 6103(k)(6) permits disclosure only of return information, not the return (including schedules and attachments) itself. If necessary, a revenue agent may disclose return information extracted from a return when questioning a third party witness. Thus, the revenue agent could have extracted the amount of cost of goods sold from the Schedule C and disclosed that amount to the third party witness.
Example 3. A special agent is conducting a criminal investigation of a taxpayer, a doctor, for tax evasion. Notwithstanding the records provided by the taxpayer and the taxpayer's bank, the special agent decided to obtain information from the taxpayer's patients to verify amounts paid to the taxpayer for his services. Accordingly, the special agent sent letters to the taxpayer's patients to verify these amounts. In the letters, the agent disclosed that he was a special agent with IRS-CI and that he was conducting a criminal investigation of the taxpayer. Section 6103(k)(6) permits these disclosures (including the special agent disclosing his affiliation with CI and the nature of the investigation) to confirm the taxpayer's income. The decision whether to verify information already obtained is a matter of investigative judgment and is not limited by section 6103(k)(6).
Example 4. Corporation A requests a private letter ruling (PLR) as to the tax consequences of a planned transaction. Corporation A has represented that it is in compliance with laws administered by Agency B that may relate to the tax consequences of the proposed transaction. Further information is needed from Agency B relating to possible tax consequences. Under section 6103(k)(6), the IRS may disclose Corporation A's return information to Agency B to the extent necessary to obtain information from Agency B for the purpose of properly considering the tax consequences of the proposed transaction that is the subject of the PLR.
