Foreign Corporations
Our team specializes in helping foreign corporations navigate complex U.S. tax obligations, ensuring IRS and state compliance while utilizing treaty benefits.
What is a foreign corporation
A foreign corporation is a business entity incorporated outside of the United States but engaged in certain activities within the U.S. that may trigger tax or reporting obligations. This includes organizations operating in their home countries while having a U.S. presence, such as conducting business, owning assets, or engaging with customers in the U.S.
Navigating U.S. tax laws as a foreign corporation can be daunting, with complex rules and potential penalties. TMP provides expert support to help you meet IRS and State compliance requirements and minimizing risks.

Frequently Asked Questions (FAQs)
Find answers to common questions about Democracy
A foreign corporation is considered to be engaged in a trade or business in the U.S. when it has business activities within the U.S. (e.g. selling products, providing services, operating a branch). Income connected with that U.S. trade or business (ECI) is subject to the standard corporate income tax rate of 21%.
The penalty for filing Form 1120 after the due date (including extensions) is 5% of the unpaid tax for each month (or part of a month) the return is late, up to a maximum of 25% of the unpaid tax.
U.S. source income that is not connected with a trade or business in the U.S. is generally income that is passive in nature and commonly includes interest, dividends, rents and royalties. The U.S. payer will withhold tax at 30% (or a lower treaty rate) of the income.
Yes, if the foreign corporation is engaged in a trade or business in the U.S., it needs to apply for an EIN in order to file Form 1120-F U.S. Income Tax Return of a Foreign Corporation.
Yes, Form 1120-F needs to be filed when the foreign corp was engaged in a U.S. trade/business, even if there was no income generated from that trade or business.
A “PE” means having a fixed place of business or dependent agents within the U.S. When your Canadian corporation leases an office space or hires employees in the U.S., among other activities, it shall have established a PE in the U.S.
Yes, Form 1120-F needs to be filed when the Canadian corp was engaged in a U.S. trade/business, even if the income from that trade/business is exempt under the tax treaty. In this case, the Canadian corporation only needs to file a protective return, which is a simplified Form 1120-F, and attach Form 8833 Treaty-Based Return Position Disclosure.
For foreign corporations with an office or place of business in the U.S., Form 1120-F is generally due on the 15th day of the fourth month following the end of a corporation’s tax year.
For foreign corporations with no office or place of business in the U.S., Form 1120-F is generally due on the 15th day of the sixth month following the end of a corporation’s tax year.
The corporation can request a 6-month extension by filing Form 7004.
The foreign corporation has to pay any U.S. corporate tax owed by the tax return due date of Form 1120-F. If the corporation filed Form 7004 to extend the return due date, it must still pay the tax owed by the original return due date.
Yes, many countries (including Canada) allow foreign tax credits for taxes imposed by a foreign country on income earned from that country. The foreign tax credit serves as a tax offset against the tax imposed by the foreign corporation’s home country on the same income.
No, you do not have to accept the default federal tax classification. A single-member LLC can elect to be treated as a corporation instead of as a disregarded entity. A multi-member LLC can also elect to be treated as a corporation instead of as a partnership. To change the classification, Form 8832 is used.
Yes, a U.S. company can be wholly or partially owned by a foreign company or individuals. However, ownership may trigger additional reporting requirements, such as filing Form 5472 to disclose foreign ownership and certain related transactions.
Yes, foreign companies operating in the U.S. are subject to U.S. laws, including federal and state tax laws, labor regulations, and industry-specific compliance requirements, depending on their activities within the country.
Yes, a foreign corporation can open a U.S. bank account. Most banks require documentation such as the corporation’s articles of incorporation, proof of business activity in the U.S., and an Employer Identification Number (EIN) from the IRS.
Yes, foreign corporations can own real estate and other property in the U.S. However, they may face additional tax and reporting requirements, such as the Foreign Investment in Real Property Tax Act (FIRPTA) for real estate transactions.
Foreign corporations may benefit from access to the U.S. market, business-friendly regulations, and tax treaties that reduce withholding taxes on certain income. Structuring as a foreign corporation can also help manage global tax liabilities.
A controlled foreign corporation (CFC) is a foreign corporation where U.S. shareholders own more than 50% of the total combined voting power or value. CFCs are subject to specific U.S. tax rules, such as Subpart F income and Global Intangible Low-Taxed Income (GILTI), which aim to tax income earned abroad by U.S. shareholders.
It depends. A nexus analysis is needed to determine if a foreign corporation has sufficient ties to a state to be subject to tax.
Nexus can be established through:
Physical presence (offices, employees, or property),
Economic activity (meeting revenue thresholds), or
Affiliations with in-state entities.
Since each state has different rules, a detailed Nexus Study is essential to ensure compliance.
