The IRS Mission

Provide America’s taxpayers top-quality service by helping them understand and meet their tax responsibilities and enforce the law with integrity and fairness to all.

Introduction

The Internal Revenue Bulletin is the authoritative instrument of the Commissioner of Internal Revenue for announcing official rulings and procedures of the Internal Revenue Service and for publishing Treasury Decisions, Executive Orders, Tax Conventions, legislation, court decisions, and other items of general interest. It is published weekly.

It is the policy of the Service to publish in the Bulletin all substantive rulings necessary to promote a uniform application of the tax laws, including all rulings that supersede, revoke, modify, or amend any of those previously published in the Bulletin. All published rulings apply retroactively unless otherwise indicated. Procedures relating solely to matters of internal management are not published; however, statements of internal practices and procedures that affect the rights and duties of taxpayers are published.

Revenue rulings represent the conclusions of the Service on the application of the law to the pivotal facts stated in the revenue ruling. In those based on positions taken in rulings to taxpayers or technical advice to Service field offices, identifying details and information of a confidential nature are deleted to prevent unwarranted invasions of privacy and to comply with statutory requirements.

Rulings and procedures reported in the Bulletin do not have the force and effect of Treasury Department Regulations, but they may be used as precedents. Unpublished rulings will not be relied on, used, or cited as precedents by Service personnel in the disposition of other cases. In applying published rulings and procedures, the effect of subsequent legislation, regulations, court decisions, rulings, and procedures must be considered, and Service personnel and others concerned are cautioned against reaching the same conclusions in other cases unless the facts and circumstances are substantially the same.

The Bulletin is divided into four parts as follows:

Part I.—1986 Code. This part includes rulings and decisions based on provisions of the Internal Revenue Code of 1986.

Part II.—Treaties and Tax Legislation. This part is divided into two subparts as follows: Subpart A, Tax Conventions and Other Related Items, and Subpart B, Legislation and Related Committee Reports.

Part III.—Administrative, Procedural, and Miscellaneous. To the extent practicable, pertinent cross references to these subjects are contained in the other Parts and Subparts. Also included in this part are Bank Secrecy Act Administrative Rulings. Bank Secrecy Act Administrative Rulings are issued by the Department of the Treasury’s Office of the Assistant Secretary (Enforcement).

Part IV.—Items of General Interest. This part includes notices of proposed rulemakings, disbarment and suspension lists, and announcements.

The last Bulletin for each month includes a cumulative index for the matters published during the preceding months. These monthly indexes are cumulated on a semiannual basis, and are published in the last Bulletin of each semiannual period.

Part I

Section 61.—Gross Income Defined

Rev. Rul. 2025-9

For purposes of the taxation of fringe benefits under section 61 of the Internal Revenue Code, section 1.61-21(g) of the Income Tax Regulations provides a rule for valuing noncommercial flights on employer-provided aircraft. Section 1.61-21(g)(5) provides an aircraft valuation formula to determine the value of such flights. The value of a flight is determined under the base aircraft valuation formula (also known as the Standard Industry Fare Level formula or SIFL) by multiplying the SIFL cents-per-mile rates applicable for the period during which the flight was taken by the appropriate aircraft multiple provided in section 1.61-21(g)(7) and then adding the applicable terminal charge. The SIFL cents-per-mile rates in the formula and the terminal charge are calculated by the Department of Transportation (DOT) and are reviewed semi-annually.

The following chart sets forth the terminal charge and SIFL mileage rates:

Period During Which the Flight Is Taken Terminal Charge SIFL Mileage Rates
1/1/25 - 6/30/25 $52.44 Up to 500 miles
    = $.2869 per mile
    501-1500 miles
    = $.2187 per mile
    Over 1500 miles
    = $.2103 per mile
 

DRAFTING INFORMATION

The principal author of this revenue ruling is Kathleen Edmondson of the Office of Associate Chief Counsel (Employee Benefits, Exempt Organizations and Employment Taxes). For further information regarding this revenue ruling, contact Ms. Edmondson at (202) 317-6798 (not a toll-free call).

Part III

2025 Calendar Year Resident Population Figures

Notice 2025-18

This notice advises State and local housing credit agencies that allocate low-income housing tax credits under § 42 of the Internal Revenue Code, and States and other issuers of tax-exempt private activity bonds under § 141, of the population figures to use in calculating: (1) the 2025 calendar year population-based component of the State housing credit ceiling (Credit Ceiling) under § 42(h)(3)(C)(ii); (2) the 2025 calendar year volume cap (Volume Cap) under § 146; and (3) the 2025 volume limit (Volume Limit) under § 142(k)(5).

Generally, the population-based component of both the Credit Ceiling and the Volume Cap are determined under § 146(j), which requires determining the population figures for any calendar year on the basis of the most recent census estimate of the resident population of a State (or issuing authority) released by the U.S. Census Bureau before the beginning of the calendar year. Similarly, § 142(k)(5) bases the Volume Limit on the State population.

Sections 42(h)(3)(H) and 146(d)(2) require adjusting for inflation the population-based component of the Credit Ceiling and the Volume Cap. The Credit Ceiling adjustment for the 2025 calendar year is in Rev. Proc. 2024-40; 2024-45 I.R.B. 1100. Section 2.09 of Rev. Proc. 2024-40 provides that, for calendar year 2025, the amount for calculating the Credit Ceiling under § 42(h)(3)(C)(ii) is the greater of $3.00 multiplied by the State population, or $3,455,000. Further, section 2.20 of Rev. Proc. 2024-40 provides that the amount for calculating the Volume Cap under § 146(d)(1) for calendar year 2025 is the greater of $130 multiplied by the State population, or $388,780,000.

For the 50 states, the District of Columbia, and Puerto Rico, the population figures for calculating the Credit Ceiling, the Volume Cap, and the Volume Limit for the 2025 calendar year are the resident population estimates released electronically by the U.S. Census Bureau on December 19, 2024, and described in Press Release CB24-213. For American Samoa, Guam, the Northern Mariana Islands, and the U.S. Virgin Islands, the population figures for the 2025 calendar year are the 2024 midyear population figures in the U.S. Census Bureau’s International Data Base.

Definition of Terms

Revenue rulings and revenue procedures (hereinafter referred to as “rulings”) that have an effect on previous rulings use the following defined terms to describe the effect:

Amplified describes a situation where no change is being made in a prior published position, but the prior position is being extended to apply to a variation of the fact situation set forth therein. Thus, if an earlier ruling held that a principle applied to A, and the new ruling holds that the same principle also applies to B, the earlier ruling is amplified. (Compare with modified, below).

Clarified is used in those instances where the language in a prior ruling is being made clear because the language has caused, or may cause, some confusion. It is not used where a position in a prior ruling is being changed.

Distinguished describes a situation where a ruling mentions a previously published ruling and points out an essential difference between them.

Modified is used where the substance of a previously published position is being changed. Thus, if a prior ruling held that a principle applied to A but not to B, and the new ruling holds that it applies to both A and B, the prior ruling is modified because it corrects a published position. (Compare with amplified and clarified, above).

Obsoleted describes a previously published ruling that is not considered determinative with respect to future transactions. This term is most commonly used in a ruling that lists previously published rulings that are obsoleted because of changes in laws or regulations. A ruling may also be obsoleted because the substance has been included in regulations subsequently adopted.

Revoked describes situations where the position in the previously published ruling is not correct and the correct position is being stated in a new ruling.

Superseded describes a situation where the new ruling does nothing more than restate the substance and situation of a previously published ruling (or rulings). Thus, the term is used to republish under the 1986 Code and regulations the same position published under the 1939 Code and regulations. The term is also used when it is desired to republish in a single ruling a series of situations, names, etc., that were previously published over a period of time in separate rulings. If the new ruling does more than restate the substance of a prior ruling, a combination of terms is used. For example, modified and superseded describes a situation where the substance of a previously published ruling is being changed in part and is continued without change in part and it is desired to restate the valid portion of the previously published ruling in a new ruling that is self contained. In this case, the previously published ruling is first modified and then, as modified, is superseded.

Supplemented is used in situations in which a list, such as a list of the names of countries, is published in a ruling and that list is expanded by adding further names in subsequent rulings. After the original ruling has been supplemented several times, a new ruling may be published that includes the list in the original ruling and the additions, and supersedes all prior rulings in the series.

Suspended is used in rare situations to show that the previous published rulings will not be applied pending some future action such as the issuance of new or amended regulations, the outcome of cases in litigation, or the outcome of a Service study.
