Do U.S. Companies Have to Pay Taxes After Registration? Unveiling the Truth and Details of Tax Rules

In the United States, whether it's a local business or a multinational corporation setting up a branch in the country, tax issues have always been an unavoidable topic. In recent years, with the increasing complexity of the global economy and continuous adjustments to tax laws in various countries, many enterprises have had more questions about U.S. tax rules. Especially for entrepreneurs who have just established or plan to register companies in the U.S., whether a company needs to pay taxes after registering in the U.S. has become a core issue. This article will start from the basic framework of U.S. tax law, combined with recent relevant news, delve into this topic, and unveil the truth and details.

Overview of the U.S. Tax System

The U.S. tax system mainly consists of federal taxes and state taxes. Federal taxes are collected by the Internal Revenue Service IRS, while each state formulates independent state tax policies based on its own laws. For companies, the main types of taxes involved are

1. Federal Income Tax All companies operating in the U.S. and generating income need to pay federal income tax. The tax rate varies depending on the scale and type of the company's income.

2. State Income Tax Not all states levy corporate income tax; for example, Texas and Nevada do not impose corporate income tax. However, for companies in other states, this tax burden is unavoidable.

3. Payroll Tax If the company has employees, it also needs to pay federal and Social Security taxes FICA, which are mandatory deductions for employee wages.

4. Sales Tax Although sales tax is an indirect tax, if the company engages in retail business, it must comply with local regulations.

It is worth noting that the U.S. adopts the territorial principle, meaning that as long as a company conducts business activities in the U.S., regardless of where it is registered, it may be considered a U.S. tax resident and thus required to fulfill its tax obligations.

Recent News Highlights The Impact of Tax Reform

The Tax Cuts and Jobs Act TCJA passed at the end of 2017 had a profound impact on U.S. corporate taxation. This bill significantly reduced the corporate income tax rate from 35% to 21%, while simplifying some tax incentive provisions. This change attracted the attention of many foreign investors and allowed many domestic U.S. companies to enjoy tangible benefits.

However, at the same time, there were voices pointing out that due to intensified international tax competition, some countries began to tighten anti-tax avoidance measures, making tax planning for cross-border transactions more complex. For example, in early 2025, the EU announced further strengthening of the enforcement of digital services tax, posing a challenge to U.S. tech giants that rely on internet platforms for profitability.

The call for a globally implemented minimum effective tax rate is gaining momentum, forcing the U.S. to reassess its own tax policies. It can be foreseen that in the coming years, the tax environment for U.S. companies may undergo another round of changes.

Specific Situation Analysis Different Types of Company Tax Requirements

Companies registered in the U.S. can generally be categorized into three types sole proprietorships, partnerships, and limited liability companies LLCs. Each type of company follows different tax rules

Sole Proprietorship These businesses typically do not file separate tax returns but include their profits or losses in personal income tax filings.

Partnership Partners need to declare income or losses according to their respective distribution ratios, and the partnership itself does not pay federal income tax.

Limited Liability Company LLC An LLC can choose to be taxed as either an S-Corp or a C-Corp. The former allows avoiding double taxation, while the latter applies to larger-scale enterprises.

For large public companies, tax processing is more complicated, requiring regular submission of detailed financial statements and facing strict audit procedures. For example, Tesla has sparked numerous controversies over its tax planning in recent years, even drawing attention from congressional hearings.
