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.

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 Unpublished rulings will not be relied on, used, or cited as precedents by Service personnel in the disposition of other cases.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.

Actions Relating to Court Decisions

It is the policy of the Internal Reve­ nue Service to announce at an early date whether it will follow the holdings in cer­ tain cases. An Action on Decision is the document making such an announcement. An Action on Decision will be issued at the discretion of the Service only on un­ appealed issues decided adverse to the government. Generally, an Action on De­ cision is issued where its guidance would be helpful to Service personnel working with the same or similar issues. Unlike a Treasury Regulation or a Revenue Ruling, an Action on Decision is not an affirma­ tive statement of Service position. It is not intended to serve as public guidance and may not be cited as precedent.

Actions on Decisions shall be relied upon within the Service only as conclu­ sions applying the law to the facts in the particular case at the time the Action on Decision was issued. Caution should be exercised in extending the recommenda­

tion of the Action on Decision to similar cases where the facts are different. More­ over, the recommendation in the Action on Decision may be superseded by new legislation, regulations, rulings, cases, or Actions on Decisions.

Prior to 1991, the Service published acquiescence or nonacquiescence only in certain regular Tax Court opinions. The Service has expanded its acquiescence program to include other civil tax cases where guidance is determined to be help­ ful. Accordingly, the Service now may acquiesce or nonacquiesce in the holdings of memorandum Tax Court opinions, as well as those of the United States District Courts, Claims Court, and Circuit Courts of Appeal. Regardless of the court decid­ ing the case, the recommendation of any Action on Decision will be published in the Internal Revenue Bulletin .

The recommendation in every Action on Decision will be summarized as ac­ quiescence, acquiescence in result only, or nonacquiescence. Both “acquies­ cence” and “acquiescence in result only” mean that the Service accepts the holding

of the court in a case and that the Ser­ vice will follow it in disposing of cases with the same controlling facts. How­ ever, “acqui­escence” indicates neither approval nor disapproval of the reasons assigned by the court for its conclusions; whereas, “acqui­escence in result only” indicates disagree­ment or concern with some or all of those reasons. “Nonacqui­ escence” signifies that, although no fur­ ther review was sought, the Service does not agree with the hold­ing of the court and, generally, will not follow the deci­ sion in disposing of cases involving other taxpayers. In reference to an opinion of a circuit court of appeals, a “nonacquies­ cence” indicates that the Ser­vice will not follow the holding on a na­tionwide ba­ sis. However, the Service will recognize the precedential impact of the opinion on cases arising within the venue of the de­ ciding circuit.

The Commissioner does NOT ACQUI­ ESCE in the following decision:

TriNet Group, Inc. v. United States of America, 979 F.3d 1311 (11th Cir. 2020). ¹

1 Nonacquiescence to the holdings that Gevity, rather than its clients, had “control of the payment of wages” and that Gevity was the statutory employer under I.R.C. § 3401(d).

Bulletin No. 2021–24 1199 June 14, 2021

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 1.6121(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

Unadjusted SIFL Rate

Period During Which the Flight Is Taken

Terminal SIFL Mileage Charge Rates

the Department of Transportation (DOT) and are reviewed semi-annually.

According to DOT, due to the effect of the COVID-19 pandemic, airline indus­ try capacity (as measured by airline seat miles) was reduced faster than airline in­ dustry expenses were reduced. Generally, the SIFL rate is the result of airline indus­ try expenses divided by airline seat miles. Because airline seat miles were reduced faster than airline industry expenses, the SIFL rate for the 6-month Tax Period Ef­ fective 1/1/2021 increased substantially.

Furthermore, in March 2020, the Coro­ navirus Aid, Relief, and Economic Securi­ ty Act was enacted, directing the Treasury Department to allot up to $25 billion for domestic carriers to cover payroll expens­ es via grants and promissory notes, known as the Payroll Support Program (PSP). The PSP grants and PSP promissory notes off­

set airline industry expenses. Accordingly, DOT provided two alternatives to incorpo­ rate differing levels of the PSP into the SIFL rate calculations to both account for the PSP in the rate calculations and to mitigate the pandemic impact on the SIFL rate. One cal­ culation adjusts the SIFL rates to account for PSP grants only while the other calculation adjusts the SIFL rates to account for both the PSP grants and PSP promissory notes.

This revenue ruling contains these three SIFL rates: (1) the Unadjusted SIFL Rate, (2) the SIFL Rate Adjusted for PSP Grants, and (3) the SIFL Rate Adjusted for PSP Grants and Promissory Notes. Taxpayers may use any of the three rates when determining the value on noncom­ mercial flights of employer-provided air­ craft under section 1.61-21(g).

The following charts set forth the ter­ minal charges and SIFL mileage rates:

1/1/21 - 6/30/21 $61.88 Up to 500 miles = $.3385 per mile

501-1500 miles = $.2581 per mile

Over 1500 miles = $.2481 per mile SIFL Rate Adjusted for PSP Grants

1/1/21 - 6/30/21 $44.35 Up to 500 miles = $.2426 per mile

501-1500 miles = $.1850 per mile

Over 1500 miles = $.1778 per mile SIFL Rate Adjusted for PSP Grants and Promissory Notes

1/1/21 - 6/30/21 $38.03 Up to 500 miles = $.2080 per mile

501-1500 miles = $.1586 per mile

Over 1500 miles = $.1525 per mile

Bulletin No. 2021–24 1201 June 14, 2021

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 pub­ lished 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 ap­ plied 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 be­ ing made clear because the language has caused, or may cause, some confusion. It is not used where a position in a prior rul­ ing is being changed.

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

new ruling does more than restate the sub­ stance 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 previous­ ly 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 rul­ ings in the series.

where a ruling mentions a previously pub­ the 1986 Code and regulations the same Suspended is used in rare situations to lished ruling and points out an essential position published under the 1939 Code show that the previous published rulings difference between them. and regulations. The term is also used will not be applied pending some future

Modified is used where the substance when it is desired to republish in a single action such as the issuance of new or of a previously published position is being ruling a series of situations, names, etc., amended regulations, the outcome of cas­ changed. Thus, if a prior ruling held that a that were previously published over a es in litigation, or the outcome of a Ser­ principle applied to A but not to B, and the period of time in separate rulings. If the vice study.

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 pub­ lished ruling that is not considered deter­ minative 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
