(Authority is based on court rank and jurisdiction and date of decision.) The following information summarizes the weight of authority from highest to lowest in order to determine whether these sources can be used for a tax situation. The courts can rule on the law. They may also interpret the statutes published by the Congress. The courts have developed various rules of legal interpretation that are used for this purpose (here is an example of legal construction in action). (This is the basis of all federal tax authorities.) Final (supreme authority issued by the Department of Finance, which binds the IRS; subject to a change in IRC) (These interpret and provide instructions for complying with legal laws; they are published in the Federal Register.) The authority of these opinions depends on the court that wrote the notice and when it was written. The courts themselves limit the precedent of their legal opinions. For example, the U.S. Tax Court regularly issues advisory opinions, memorandum opinions and summary opinions. Summary opinions have no precedent value, and memory opinions have limited precedent value.
CPAs should carefully evaluate the research tools available to them. In this digital age, many resources are available online. Tax research tools will be different for each CPA firm and will depend on areas of practice, client size and budget. The relative authority of sources must be kept in mind. Some sources are not authoritative and provide only advice; These sources should not be cited as legal authority. The IRS is organized to perform the duties of Secretary of the Treasury under Section 7801 of the Internal Revenue Code. The Secretary has full authority to administer and enforce domestic tax laws and has the power to establish a body to enforce those laws. The IRS was created on the basis of this statutory grant. Revenue Rulings (official interpretation of IRC by the IRS, related laws, tax treaties, and regulations and can be used and cited as an authority) (This is the highest authority – the power of Congress to enact tax laws.) Temporary legislation (which provides guidance until final regulations are published and has the same authority as final regulations) is the primary source of federal tax law; they are the supreme law of the land outside the Constitution (and the tax treaties discussed below). Because of the importance of statutory law, the legislative history underlying the enactment of these statutes is also an important source of federal tax law.
This legislative history may consist of reports from judicial committees or even documented debates in the House of Representatives or the Senate. (These are unofficial sources that carry less authority weight than primary sources; they should not be cited as authoritative.) Proposed (generally not binding unless otherwise specified by the IRS) There are many sources of tax law that tax professionals (and the taxpayer representing themselves) need to know in order to effectively resolve a tax dispute. These sources can be divided into legislative, administrative and judicial sources. The IRS is an office of the Department of Finance and one of the most effective tax administrators in the world. In fiscal 2020, the IRS generated nearly $3.5 trillion in revenue and processed more than 240 million tax returns. The majority of these laws are published in Title 26 of the United States Code and are often referred to as the Internal Revenue Code (IRC). However, other tax laws appear outside the IRC. For example, several tax provisions relating to pension benefits are contained in Title 29 of the United States Code, which is part of the Labor Code.
Provide world-class service to U.S. taxpayers by helping them understand and comply with their tax obligations and apply the law with integrity and fairness for all. Notice (These contain notices that include substantive interpretations of IRC or other legal provisions.) Tax treaties and laws bind the IRS and the courts. However, the courts can declare both laws null and void. IRS documents provide additional sources of federal tax law. Many of these documents are published weekly in the Internal Revenue Bulletin. These are accumulated every six months and published in the cumulative bulletin. These documents include tax rulings, tax procedures, communications and notices.
