IRS Rulings (e.g., Letter Rulings, Technical Advice Memoranda and Chief Counsel Advisories) published in the last few years are generally available on The trick is knowing how to find them. This overview provides key navigation tips to locate desired Rulings.

First, visit This Web page houses detailed information on how to locate a form or publication, such as Form 637 (Registration) or Publication 510 (Excise Taxes). (Please be aware, if you know the title or number of a given form or publication, you should be able to easily locate it using the primary search box. Unfortunately, this does not work with IRS Rulings.) 

For IRS Rulings, visit On this page, you can search by number, Uniform Issue List Codes (UILC) or subject. The simplest way to obtain a Ruling from this page is by using its identifying number. If you have this information, type it into the “Find” box, select “Number” for the second box (the default search option) and click “Find.” The desired link should appear. (A sample number of a recent Letter Ruling is 201447001, which means it became available to the public in the 47th week of 2014.) If you have the specific number, you can obtain the decision by simply typing it into your preferred online search engine. 

Often, people do not have the actual number of the Ruling they seek. In this case, change the second box to “UILC” and type the statutory code section in the “Find” box. For example, most FET Rulings on heavy trucks and trailers are decided under Internal Revenue Code (IRC) 4051, so the one you are trying to find will likely show up under UILC 4051. If not, you could also try UILC 4052, 4053 and 4221. This search type will give you a list of IRS Rulings with the given UILC in chronological order (most recent to oldest). Using this method, the oldest currently available decision was published in 1999. (Please note, if you know the approximate year of publication, it will be much easier to locate.) 

The last alternative is by subject, but, unfortunately, this is not a general key word search index. For example, if looking for a Ruling on the feed, seed and fertilizer exemption, you cannot simply type seed or fertilizer. Instead, it only recognizes subject titles tied to related UILC. The title of UILC 4051, for instance, is “Imposition of Tax on Heavy Trucks and Trailers Sold at Retail (Taxable v. Nontaxable).” If you type in key words from this subject title, such as heavy trucks, you will generally pull up most (but not necessarily all) of the same decisions available using UILC search 4051. 

This search will be broader than a subject listing. If the Ruling addresses a specific sub-issue under 4051, the IRS may use a different subject title. If a Ruling decided under IRC 4051 has a UILC of 4051.03, although it is a 4051 UILC search result, it does not appear by subject using the term heavy trucks. The IRS uses the subject title “Separate Purchase of Vehicle and Parts or Accessories” for Rulings addressing sub-issue .03. Therefore, it makes sense to use the broader UILC search terms 4051, 4052, 4053 and 4221 instead of trying to learn and remember the separate titles and potential subtitles for each UILC.

If you cannot find a particular Ruling on, consider contacting your accountant or tax consultant who might have access to other databases.
