Part III. Seller Certification
SECTION 1. PURPOSE
Internal Revenue Bulletin 2007-4 · 2026-10-03 edition · updated 2026-10-04 · United States
.01 This revenue procedure permits a taxpayer under the jurisdiction of the Large and Mid-Size Business Division to request that the Service examine specific issues relating to tax returns before those returns are filed. This revenue procedure supersedes Rev. Proc. 2005–12, 2005–1 C.B. 311. This revenue procedure provides the framework within which a taxpayer and the Service may work together in a cooperative environment to resolve, after examination, issues accepted into the program. If the taxpayer and the Service are able to resolve the examined issues before the returns that they affect are filed, this revenue procedure authorizes the taxpayer and the Service to memorialize their agreement by
executing an LMSB Pre-Filing Agreement (PFA).
.02 This revenue procedure outlines the procedures for resolving issues through pre-filing examinations. Taxpayers and the Service often resolve issues more effectively and efficiently through a pre-filing examination than a post-filing examination, because the taxpayer and the Service have more timely access to the records and personnel that are relevant to the issues. A pre-filing examination also provides the taxpayer with certainty regarding the examined issue at an earlier point in time than a post-filing examination. These procedures benefit both taxpayers and the Service by improving the quality of tax compliance while reducing costs, burdens, and delays. Unlike letter rulings and other forms of written

but also require that the Associate Chief Counsel (International) concur with the acceptance of the issue into the PFA Program and execution of the PFA. Even though an issue in a particular case appears on this list, the Service may, in its sole discretion, refuse to address that issue based on considerations of sound tax administration. The eligible issues are:
(1) whether a unit of the taxpayer’s trade or business is a qualified business unit within the meaning of section 989(a) and the regulations promulgated under that section;
(2) whether the taxpayer is engaged in a trade or business within the United States (excluding questions under section 864(b)(2)); (3) the amount of gross income that is effectively connected with the conduct by the taxpayer of a trade or business within the United States;
(4) factual determinations concerning the extent to which, under section 882(c), deductions are connected with income that is effectively connected with the taxpayer’s conduct of a trade or business within the United States; and
(5) whether the taxpayer has a permanent establishment in the United States for purposes of a bilateral income tax convention to which the United States is a party and, if so, what profits are attributable to that permanent establishment.
.07 Special provisions for requests on international issues . The provisions of this section apply, in addition to the generally applicable provisions of this revenue procedure, to any request for a PFA on an issue having international implications.
(1) A PFA and any factual information contained in the background files is subject to exchange of information under income tax treaties or tax information exchange agreements in accordance with the terms of such treaties and agreements (including terms regarding relevancy, confidentiality, and the protection of trade secrets). In cases where the exchange of information would be discretionary, information may be exchanged to the extent consistent with sound tax administration and the practices of the relevant foreign competent authority.
(2) To minimize taxpayer and governmental uncertainty and administrative cost, taxpayers who seek a PFA on an
to current or prior taxable years for which returns were neither due nor filed, taxpayers and the Service could not resolve issues for multiple future taxable years or issues regarding appropriate methodologies for determining tax consequences that would affect future taxable years.
.03 In Rev. Proc. 2005–12, the Service expanded the scope of the PFA program by allowing taxpayers and the Service to address certain issues over a limited number of future taxable years. In addition, the Service revised the domestic and international issues eligible for the PFA program. Section 12 of Rev. Proc. 2005–12 provided that that revenue procedure would remain in effect until December 31, 2006, unless sooner revoked, modified, or superseded.
.04 The Service has determined to renew the PFA program as described in Rev. Proc. 2005–12 with minimal changes. This revenue procedure largely continues the existing PFA program, clarifying procedures for processing a PFA request and updating the user fee requirements for a PFA. The objective of the PFA program remains to resolve, before returns are filed, issues that are likely to be disputed in post-filing audits.
