Confidentiality of the Taxpayer Identification Number under the Internal Revenue Code

Section 6109 of the Internal Revenue Code makes an individual’s Social Security number the individual’s taxpayer identification number [TIN]. The same section requires taxpayers to furnish their TINS to the Internal Revenue Service and to other persons whenever the Internal Revenue Service determines that securing the proper identification of the person is necessary. Many Code sections require taxpayers to collect and furnish the TINS of third-parties with whom they have dealings in order to claim a benefit or a deduction. The first part of this report compiles instances in which individuals must furnish their TINS or the TINS of another person in order to file their tax return. The second and third parts examine the times when a taxpayer must furnish a TIN to a third party and the times when the Code permits disclosure of tax return information (which usually contains the TIN) to other parties. The last part discusses penalties for improper disclosure of tax return information and penalties for failing to disclose a TIN when required to furnish it.

Summary

Section 6109 of the Internal Revenue Code makes an individual's Social Security number the individual's taxpayer identification number [TIN]. The same section requires taxpayers to furnish their TINS to the Internal Revenue Service and to other persons whenever the Internal Revenue Service determines that securing the proper identification of the person is necessary. Many Code sections require taxpayers to collect and furnish the TINS of third-parties with whom they have dealings in order to claim a benefit or a deduction. The first part of this report compiles instances in which individuals must furnish their TINS or the TINS of another person in order to file their tax return. The second and third parts examine the times when a taxpayer must furnish a TIN to a third party and the times when the Code permits disclosure of tax return information (which usually contains the TIN) to other parties. The last part discusses penalties for improper disclosure of tax return information and penalties for failing to disclose a TIN when required to furnish it.


Confidentiality of the Taxpayer Identification Number under the Internal Revenue Code

Background

In October 1961, Congress authorized the Internal Revenue Service to require identifying numbers on tax returns.1 Fifteen years later, the Tax Reform Act of 19762 codified IRS practice that the Social Security number was to be used as the identifying number for individuals. Since that time Congress has adopted many provisions which require individuals to furnish their TINs or the TINs of other persons with whom they have dealings in order to claim a tax benefit or to enable the IRS to match returns with information reports in order to verify claims on returns. This report is intended to illustrate the wide variety of situations in which individuals are required by the Internal Revenue Code to furnish their taxpayer identification numbers, either to the IRS or to third parties.

TINS on Taxpayer's Return

The table below lists Code sections which require taxpayers to furnish either their TIN or another person's TIN on their individual tax returns.

TINs to Third Parties

In a wide variety of situations, the Internal Revenue Code requires taxpayers to give their TINs to third parties. Often the requirement is deemed necessary in order to permit the IRS to match the income and deduction side of the same transaction or to verify that the proper tax rates were used or the proper amount of tax was withheld or reported. The more persons with whom a taxpayer may be doing business or from whom a taxpayer may be receiving income the more persons there will be who are entitled to know a taxpayer's TIN.

Recently, there has been recognition that in some instances having to provide a TIN may make one vulnerable to identity theft.4 Beginning with returns prepared after 1999, individual tax return preparers are permitted to request an alternative "Preparer Tax Identification Number" for use when preparing tax returns. Although there is no pending legislation to extend this idea to other taxpayers, this does provide a precedent for individuals having a public and a private TIN.

Table 2 below emphasizes the number of taxpayers who are required to furnish their TIN to third parties for a variety of purposes.

Permissible Disclosures

The Internal Revenue Code contains stringent penalties for disclosing taxpayers' returns and taxpayer return information. Consequently, the law is fairly explicit about when taxpayer return information may be disclosed and to whom. Most of the disclosure authority is contained in IRC § 6103. The following chart contains examples of instances in which taxpayers' returns, and thus their TINs, might be disclosed to other entities by the IRS. In many of these instances, however, the recipient of the return information may already have the taxpayer's identification number. In fact, the recipient may be required to identify the taxpayer by number in order to receive the requested return. The chart does not list the many entities that are entitled to statistical information which can only be produced in an anonymous form which does not identify a particular taxpayer directly or indirectly.

Penalties for Disclosure

The Internal Revenue Code contains two main penalties for disclosure of tax returns and tax return information. Section 7213 makes willful disclosure which is not authorized by the Internal Revenue Code a felony punishable by a fine up to $5,000 or imprisonment of not more than 5 years, or both, plus the costs of prosecution. In addition to any other punishment imposed by law, federal employees must be discharged from employment upon conviction. Different paragraphs of the section apply to federal employees and contractors and to state and local employees. In addition recipients of information which was not authorized to be disclosed by the Internal Revenue Code can be subject to the same punishment for printing or publishing a return or return information in a manner not provided for by law. It is also a felony to offer to exchange any item of material value in exchange for a return or return information, and to receive in exchange for such solicitation any return or return information. The same $5,000/5-year potential penalties apply.

The second major penalty, contained in IRC § 7216, applies to tax return preparers. If any person who prepares a return for compensation knowingly or recklessly discloses any information furnished to him in connection with the preparation of a return, or knowingly or recklessly uses any such information for any purpose other than to prepare a return, then that person is guilty of a misdemeanor and can be fined up to $1,000 or imprisoned up to one year, or both, plus the costs of prosecution. There are exceptions for disclosures permitted under the Internal Revenue Code, ordered by a court, or made in order to prepare the person's state or local tax returns.

Penalties for Failing to Disclose

The principal penalty for failing to disclose one's TIN when requested is contained in IRC § 6723, which provides for a $50 penalty for each failure to comply with a "specified information reporting requirement." The maximum annual penalty is $100,000. There are also "penalties" in the sense that certain deductions cannot be taken unless a TIN is furnished or that additional withholding on certain distributions will be required. For example, IRC § 151(e) provides that no exemption shall be allowed unless the TIN of such individual is included on the return claiming the exemption. The loss of the exemption amount may exceed the $50 penalty amount. Under IRC §§ 3405 and 3406, backup withholding is required unless the taxpayer furnishes the proper TIN to the payer of income.

Beginning in November 1999, tax return preparers can obtain a "preparer tax identification number" [PTIN] to use on returns which they are paid to prepare. This number is to protect the privacy of the preparer's TIN. The use of an alternative number was authorized by the IRS Restructuring and Reform Act of 1998, P.L. 105-206, § 3710.

IR-1999-72 states that the IRS Restructuring and Reform Act of 1998 authorized the use of PTINs to respond to "concerns that a preparer's SSN could be used inappropriately by clientele and others having access to a prepared return."
