Internal Revenue Service

The Internal Revenue Service is the principal Federal agency responsible for interpreting and enforcing the Tax Code. Statistics on IRS audits, collections, service, staffing, etc., are posted on the TRAC Web site.

IRS Web site is an good source for IRS forms, Publications and selected other tax-related materials (www.irs.gov). You can link to most of the key materials through the Electronic Reading Room.

You can get most other important IRS materials from Lexis and Westlaw or the leading subscription-based online tax services: RIA's Checkpoint, Tax Analysts' Federal Research Library and the CCH Standard Federal Tax Reporter on Intelliconnect. You can find many obscure IRS materials in the TNT databases on Lexis (TAXANA;TNT), and the Federal Research Library.

If you need to contact the IRS, you can try the phone numbers on the official How to Contact the IRS page. To contact the IRS attorney(s) working on a particular Code section or Regulation, see the "Code and Subject Matter Directory," Chart 5425 from the Office of Chief Counsel Telephone Directory posted here and here by Tax Analysts. For more detail, look in Tax Analysts' The Tax Directory (info on the TA web site).

Some sources I have used to get individual IRS materials are listed below.

Acquiescence and Non-Acquiescence: If the Tax Court decides against the IRS position on an issue, the IRS will sometimes issue a statement saying that they either accept the Tax Court's argument (acquiesce) or disagree with it (non-acquiesce). To find out whether the the IRS has issued an Acquiescence and Non-Acquiescence to a particular case, look in the RIA Tax Citator; they may also show up in Shepard's on Lexis or KeyCite on Westlaw. Note: In addition to the print, the RIA Tax Citator is available on Checkpoint and Westlaw (RIA-CITE).

Actions on Decisions: AODs back to 1997 are posted in the IRS Electronic Reading Room. They are also available on Westlaw (FTX-AODs) and Federal Research Library back to 1985. AODs are published in print in CCH's Actions on Decisions (1981-present).

Adverse determination letters: When the IRS turns down a request from an organization for tax-exempt status, the Service send the organization an adverse determination letter stating its reasons and providing information on how the organization can appeal the determination. For more, see the "Exemption Rulings and Adverse Determination Letters" section of the Tax-Exempt Organizations entry.

Announcements: Announcements are published in the Cumulative Bulletins and Internal Revenue Service Bulletins, discussed in the "Bulletins" section, below. They are searchable in a database with IRS Notices on Westlaw (FTX-ANN) and the Federal Research Library.

Bulletins (CBs & IRBs): Internal Revenue Bulletins (IRBs) are published weekly by the IRS. They were were compiled into Cumulative Bulletins (CBs) every six months until the IRS stopped publishing CBs in 2008. The various materials published in IRBs and CBs include IRS Revenue Rulings, Revenue Procedures, Announcements, Treasury Decisions, a few General Counsel Memos, Tax Conventions, Notices, etc. - plus selected Executive Orders and court cases.

The complete contents of IRBs are posted on the IRS Web site from 1995 to the present (www.irs.gov/businesses/topic/index.html). They are also available through the Federal Research Library from 1987, Checkpoint from 1996, Lexis from 1956 (TAXRIA;TNT), Westlaw from 1919 (FTX-CB) and CCH Intelliconnect.

IRBs and CBs are posted in digital format in the HeinOnline "U.S. Federal Agency Documents, Decisions, and Appeals" library from 1919-2008 (subscription required).

The form for pulling documents from CBs and IRBs on Lexis and Westlaw is "1985-8 cb 550" or "1985-8 irb 18". Lexis goes back to 1956 and Westlaw goes back to 1954. You can pull CBs all the way back to 1919 from Westlaw if you call (800-733-2889) and ask for the "WL" citation.

Chief Counsel Materials: Chief Counsel Advice, Chief Counsel Bulletins and other materials produced by the Chief Counsel are posted IRS Web site; you can find them in the Electronic Reading Room section of the IRS Web site, although if you're looking for something specific you may find it easier just to search with Google.

Cumulative Bulletins (CBs): See Bulletins, above.

IRS enrolled agents are listed on the National Association of Enrolled Agents Web site. Treasury Department Circular 230 explains the Regulations Governing the Practice of ... Enrolled Agents ...

General Counsel Memoranda: Westlaw has a GCM database (FTX-GCM) that covers 1962 to 2002. The Lexis GCM database (FEDTAX;GCM) covers March 1967 through November 2002; selected documents are available from October 1958 through March 1967. CCH Intelliconnect has GCMs from 1967 to 1995, with a very few GCMs going back to 1960 and a very few going up to 2007.

General Counsel Memoranda are published in a CCH publication called IRS Positions (1981-present). A few GCM have been published in Internal Revenue Bulletins and compiled in Cumulative Bulletins (until 2008, when the IRS stopped publishing Cumulative Bulletins). These publications are discussed above in the "Bulletins (CBs & IRBs)" section.

To get copies of old GCMs not available elsewhere, submit a FOIA request to the IRS, following the IRS's Freedom of Information Act (FOIA) Guidelines.

The manual is published in three parts, and the "IRS Audit Manual" refers to the auditing part.

They are also available on Checkpoint under "Federal Source Materials > IRS Practice."

Private Letter Rulings: Private Letter Rulings (PLRs) are written by the IRS National Office in response to taxpayer questions. PLRs cannot be cited a precedent, but they are still widely read and widely available. The IRS does not officially publish PLRs, but they are posted on an IRS Web site back to January, 1997 in the Electronic Reading Room.

In addition, PLRs are reported in TNT (on Lexis, Westlaw and the Federal research Library) and in BNA's Daily Tax Report the day after they become available.

You can get older PLRs on on Lexis (FEDTAX;PLR) and Westlaw (FTX-PLR) back to 1950. The form for pulling PLRs on Lexis is: "plr xxxxxxxx".

PLRs are also available from the CCH Standard Federal Tax Reporter on Intelliconnect, back to 1985, Checkpoint back to 1950, and the Federal Research Library, which has some PLRs back into the 1940s.

To get pre-1950 PLRs, file a FOIA request with the IRS, following the IRS' Freedom of Information Act Guidelines.

You can find cases citing a particular PLR using KeyCite on Westlaw.

Publications: You can get current IRS publications for free from the IRS Web site. In addition, CCH publishes Pubs in a loosleaf services called IRS Publications, and they're included in the Federal Research Library, Checkpoint and the CCH Standard Federal Tax Reporter on Intelliconnect.

Old Pubs are on Lexis and Westlaw back to 1984.

To verify information about old Pubs (or maybe to get copies), try the IRS Publications Branch at 202-622-5210. If that fails, try the IRS library (202-622-8050).

Regulations: IRS regs are published first in the Federal Register and subsequently compiled in the CFR (see "Federal Register" and "Code of Federal Regulations"). IRS Regs are also available on Lexis, Westlaw, the Federal Research Library and the the CCH Standard Federal Tax Reporter on Intelliconnect. Comments on proposed regulations are available for free on Regulations.gov as well as on Federal Research Library, and Lexis (TAXANA;TNT).

For broad coverage and better searching, Revenue Rulings and Procedures are searchable in the Federal Research Library back to 1954 and 1955, respectively, while Westlaw offers separate databases for Rulings (FTX-RR) and Procedures (FTX-RP). Westlaw provides Rulings and Procedures from 1954 in its Bulletins databases (see above). Versuslaw has IRS Rulings back to 1953.
