U.S. Tax Code: Definition, How It Works, and Global Examples

A tax code is a collection of laws and regulations that describe how governments levy and collect taxes. In essence, it represents a comprehensive set of rules that establish the rights and obligations of U.S. taxpayers, whether they are individuals or business entities.

The primary federal tax code is known as the Internal Revenue Code (IRC), also referred to as Title 26 of the United States Code. Understanding it and all the other relevant federal, state, and local tax laws is essential for individuals and business owners who need to pay their taxes and meet other financial obligations.

This article dives into the specifics of the U.S. tax code system, explaining how it works and how it's being enforced, so let’s get started!

Key Takeaways

• A tax code is a combination of regulations and rules that concentrate on the tax rights and obligations of individuals, businesses, and entities.
• The Internal Revenue Code (IRC) is the U.S. federal tax code. More specifically, it refers to Title 26 of the U.S. Tax Code.
• Congress writes the tax codes, while the Internal Revenue Service (IRS) oversees the execution of these codes once they’re passed into law.
• Tax codes differ in each country, from how they are called to how each code is assigned to individual and corporate taxpayers.

What is a Tax Code?

Tax code is a set of laws and directives defining the responsibilities and rights of taxpayers in fulfilling their federal, state, and local tax obligations. It serves as a guide, informing corporate and regular taxpayers on how to file and pay their taxes accordingly.

Elected legislative bodies at the federal, state, or local level pass tax laws, which are then compiled into the tax code. Once it is approved and becomes a law, it is then included in the existing array of tax laws and designated with a specific code section.

The U.S. tax code is enacted at the federal, state, and local levels of government. On a federal level, the Internal Revenue Service (IRS) is responsible for implementing all constitutional tax regulations, which go hand-in-hand with the rules prescribed by the Treasury Department.

Who Writes Tax Codes and Who Enforces Them?

Tax codes are written and enforced by several different government organizations to ensure a distinct separation of powers.

For starters, the U.S. Congress writes and enacts tax laws. The process typically starts with the Ways and Means Committee in the House of Representatives. Proposed bills are then debated and amended before being approved or denied.

If approved, the bill then moves to the Senate. There, the Financial Committee reviews the bill and makes final changes before giving it back to the Senate for approval. If the House and Senate versions have significant differences, a joint committee is created to find a compromise on which both parties must agree.

Finally, the bill goes to the President, who can sign it into law or veto it; however, Congress can override the veto with a two-thirds vote.

Following that, the Internal Revenue Service (IRS) is primarily responsible for enforcing the approved tax law. It performs a range of functions, including interpreting tax laws, providing guidance, collecting taxes, processing returns, and conducting audits.

The Office of Tax Policy (another body under the Department of the Treasury) assists in interpreting the Internal Revenue Code, as well as developing and implementing relevant tax programs and policies.

How Does the U.S. Tax Code Work?

For starters, let’s say Congress creates a policy and passes it into law. From there, the IRS takes charge and formulates all the rules and regulations to help ensure the said tax policy is implemented appropriately.

The U.S. federal tax code is referred to as the Internal Revenue Code (IRC). The IRC pertains to Title 26 of the U.S. Tax Code (also called the IRS tax code), and it covers all essential laws and rules tackling income taxes, tax deadlines and deductions, tax brackets, penalties, and fees, income thresholds, and filing statuses.

It is subdivided into different numbers and code sections, carefully organized based on the specific tax concern addressed by each rule.

Also included in the IRC’s long list of tax regulations are the imposition of taxes on gifts and estates, the structure governing benefits, unemployment taxes, and retirement plans. Lastly, there’s a set of guidelines on how to properly form institutional, withholding, and penalty rulings.

Important IRS Forms Related to the Tax Code

While the rules about taxes are quite intricate and exhaustive, the IRS provides all the income tax forms taxpayers need to file and pay their taxes. They also have a highly informative website that details all the crucial facts they need to file their tax returns and check their taxes owed correctly.

Aside from making essential tax forms accessible to the public, the IRS also has multiple publications designed to simplify the complicated tax regulations, income, investment, expense, and property lingo into layman’s terms for everyone’s benefit.

All these resources highlight convenience and practicality since taxpayers do not need to head to the IRS office to secure their forms or inquire about their taxes. Most of the information they need is laid out for them on the website.

Tax Codes vs. Tax Forms

Knowing the difference between tax codes and tax forms helps individuals and business entities navigate the complex U.S. tax system. In essence, the tax code “tells you the rules,” while IRS forms “help you comply with the rules.”

The tax code is a comprehensive set of rules and regulations that govern all the processes and requirements related to taxes. It defines what income is taxable and how much, as well as the deductions and credits available, who is eligible for them, who is required to pay and file taxes, and more.

This robust and complex body of law outlines the taxpayer's rights and obligations, as well as the authority of the IRS. It sets the foundation and a legal framework on which all of the tax-related processes and activities are built.

On the other hand, tax forms are documents created by the IRS to facilitate tax operations. In essence, these are financial instruments designed to standardize tax-related activities, like paying, reporting, and filing.

Tax forms provide users (both individuals and business entities) with sufficient information to help them remain compliant and fulfill their duties.

For instance, Form 1040 (U.S. Individual Income Tax Return) is used by individuals to report their annual income and calculate tax liability. On the other hand, employers issue Form W-2 (Wage and Tax Statement) to report their annual wages and taxes withheld.

The IRS has most of these forms easily accessible on its website, with detailed instructions on how to use them.

How Do Tax Codes Differ in Other Countries?

Tax codes differ in other countries.

For example, in 2022, Estonia was deemed by the OECD as the country with the best tax code. Among the deciding factors that brought Estonia’s tax code to the spotlight are the flat 20% tax rate imposed on individual income and the 20% tax rate on corporate income.

In Australia, individuals and entities use a Tax File Number (TFN) to report or relay inquiries to the Australian Taxation Office (ATO). The ATO also directs and executes all Australian tax rates, laws, and codes.

Canada’s tax laws are enforced by both the federal and provincial governments, while collecting taxes is overseen by the Canada Revenue Agency (CRA). The tax code of Canada is called the Income Tax Act.

India’s Tax Code is referred to as the Income-tax Act of 1961. Its longer title is ‘An Act to consolidate and amend the law relating to income-tax and super-tax.’

In the UK, most taxpayers with a pension or a single job typically use the 1257L tax code. The UK’s tax codes are quite distinct in that they use a combination of numbers and letters, where the numbers indicate the individual’s employer and pension provider and the letters pertain to the taxpayer’s tax situation and personal allowance.

Final Thoughts

An in-depth understanding of the U.S. tax code is essential for individuals and professional entities to meet their tax obligations and ensure compliance. Complying with relevant rules and regulations is crucial, as mistakes can result in penalties with interest and even lead to criminal charges.

On the other hand, knowing the ins and outs of the tax code can help you take advantage of the available benefits. This can help with your budgeting while improving your financial health and planning capabilities.
