The U.S. Constitution, which came into effect in 1789, gives Congress the power to levy taxes. The Internal Revenue Code (IRC) provides the foundation for all federal tax authority in the U.S. and is the ultimate authority when researching federal tax law issues. The IRC is interpreted by Treasury regulations, cases that interpret the laws, and IRS rulings. The IRC is supplemented by individual laws passed by Congress and signed into law by the President. The U.S. Tax Court is a federal trial court of record established by Congress under Article I of the U.S. Constitution. It specialises in adjudicating disputes over federal income tax, generally before formal tax assessments are made by the Internal Revenue Service. The Tax Court provides a judicial forum for affected persons to dispute tax deficiencies determined by the Commissioner of Internal Revenue before paying the disputed amounts.

What You'll Learn

The US Constitution gives Congress the power to levy taxes
The US Constitution, which came into effect in 1789, is the supreme law in the United States. It gives Congress the power to levy taxes and is subject to only one exception and two qualifications. Firstly, articles exported from any state may not be taxed. Secondly, direct taxes must be levied by the rule of apportionment, and indirect taxes by the rule of uniformity.
Article I, Section 8, Clause 1 of the Constitution provides Congress with the authority to lay and collect taxes for federal debts, the common defence, and the general welfare. This is commonly referred to as the Taxing Clause. The Framers of the Constitution and the ratifiers agreed that Congress must possess this power.
The Taxing Clause is listed first in Article I, Section 8, as it was decided that Congress must itself possess the power "to lay and collect Taxes... to pay the Debts and provide for the common Defence and general Welfare of the United States." This power is not limited to repayment of Revolutionary War debts but is also prospective.
The Constitution's grant of power to Congress to levy taxes has been, at times, substantially curtailed by judicial decisions with respect to the manner in which taxes are imposed, the objects for which they may be levied, and the subject matter of taxation.

State tax laws and their similarities to federal taxation schemes
The US Constitution, which came into effect in 1789, gives Congress the power to levy taxes. Federal tax law is enacted in the Internal Revenue Code (IRC), which forms the basis of all federal tax authority in the US. The IRC covers income, estate and gift, employment, and excise taxes, as well as procedures and administration.
State tax laws show similarities to federal taxation schemes in several ways. Each state has a regulatory tax agency that passes state administrative regulations and rulings, similar to the Internal Revenue Service at the federal level. State courts also generate judicial opinions, although most states lack a dedicated tax court.
State personal and corporate income tax issues are often researched in a similar manner to federal tax research. Many states' personal income tax is simply based on federal income tax, with some states offering credits for taxes paid to other states. Additionally, federal and state income tax is calculated and returns filed for each taxpayer.
However, states also impose a range of taxes unrelated to income, such as property taxes, sales and use taxes, excise taxes, estate and inheritance taxes, and liquor taxes. These state tax laws may be scattered across various sections of state codes and lack a cohesive "tax code".
In terms of employment, federal and state governments levy unemployment taxes on employers. While federal payroll tax non-compliance results in automatic penalties, similar penalties are also applied at the state and local levels.

The Internal Revenue Code (IRC) and its interpretation
The Internal Revenue Code (IRC) is the primary source of federal tax law in the United States. It is the definitive authority on federal tax, covering income, employment, gift, estate, and excise taxes. The IRC also provides rules for calculating taxable income, determining tax liability, filing tax returns, and enforcing tax laws.
The IRC is interpreted by Treasury regulations, which are the official interpretations provided by the US Department of the Treasury. These regulations direct taxpayers on how to comply with the IRC's requirements. They can be found in Title 26 of the Code of Federal Regulations (26 CFR). For example, regulations defining gross income can be found at 26 CFR 1.61-1.
Court decisions also play a role in interpreting the IRC. Annotations can provide insights into how a particular section of the IRC has been interpreted by the courts or the Internal Revenue Service (IRS). The IRC is further supplemented by individual laws passed by Congress and signed into law by the President. These laws amend the IRC and include additional information such as effective dates, transitional rules, and special rules.
It is important to note that tax law is subject to frequent changes. Researchers should always ensure they are referring to the most recent version of the IRC and are aware of any recent amendments or new legislation. The Internal Revenue Bulletin (IRB), published by the IRS, is the authoritative source for distributing official IRS tax guidance.

The role of the US Tax Court and its jurisdiction
The United States Tax Court is a federal trial court that was established by Congress in 1924 as the "U.S. Board of Tax Appeals" to address the increasing complexity of tax-related litigation. It was renamed the "Tax Court of the United States" in 1942, and in 1969, it was given its current formal designation, transitioning from an administrative court to a full judicial court.
The Tax Court is an independent judicial forum, unaffiliated with the Internal Revenue Service (IRS). Its role is to provide taxpayers with an avenue to dispute certain IRS determinations before they are required to pay the disputed amounts. The court's jurisdiction includes the authority to hear and decide on matters such as claims for relief from joint and several liability, review of final partnership administrative adjustments, and redetermination of interest on deficiencies or overpayments determined by the Tax Court.
The Tax Court has jurisdiction over all 50 states and holds trials in 74 U.S. cities. Cases are typically commenced by the filing of a petition, which must be timely submitted within the allowable time frame and accompanied by a $60 filing fee. Once a petition is filed, the underlying tax payment is usually postponed until the case is decided. In disputes involving $50,000 or less, taxpayers can opt for the Court's simplified small tax case procedure, which offers a less formal and faster resolution. However, decisions made through this procedure cannot be appealed.
It is important to note that the United States Tax Court does not hold exclusive jurisdiction over tax cases. Federal tax matters can also be heard and decided in U.S. District Courts, the Court of Federal Claims, and the Bankruptcy Court.

Supreme Court cases involving tax laws
The US Supreme Court has issued several rulings that have had significant impacts on tax laws and how they are interpreted. For example, in 2024, the Court issued two opinions that will have broad consequences for taxpayers seeking to challenge tax regulations. While these opinions did not stem from tax cases, they are expected to increase litigation concerning tax regulations.
The US Supreme Court also hears cases involving constitutional challenges and those involving statutory interpretation. For instance, in Mayo Foundation for Medical Education and Research v. United States, the Court implied that a special administrative standard of review applies for tax law.
In 1984, a six-justice panel of the Supreme Court gave us what became known as Chevron deference. Chevron deference required courts to defer to an agency's interpretation of a statute if the statute was silent or ambiguous on a particular issue and the agency's interpretation was reasonable.
In Commissioner v. Indianapolis Power & Light Co. (1990), the Supreme Court ruled on the issue of taxable income. The case involved a utility company that required customers with suspect credit to make deposits to assure prompt payment of future electric bills. The Court ruled that these deposits were not taxable income for the utility company upon receipt, as the company did not have complete dominion over them when they were made.
Another notable case is U.S. v. Windsor (2013), which dealt with the definition of "marriage" and "spouse" under federal law. The Court ruled that the Defense of Marriage Act's exclusion of lawfully married same-sex couples was unconstitutional, thus extending the federal estate tax exemption to surviving spouses in same-sex marriages.
