Form 1120-F is used by foreign corporations to report their US-sourced income and to calculate and pay the taxes owed on that income.
This form ensures that the IRS is aware of the business activities of foreign corporations in the US and that these corporations comply with US tax laws.
But why is this important?
Filing Form 1120-F is important for foreign corporations because it allows them to claim any applicable deductions and credits, which can reduce their taxable income.
What necessitates filing Form 1120-F?
Foreign corporations must file Form 1120-F if they are engaged in a trade or business in the United States or if they have income that is effectively connected with a US trade or business.

- Effectively Connected Income (ECI): Foreign corporations with income connected to their US operations must file the form. ECI includes income from US sources connected to the corporation’s US activities.
Here are a few examples:

- Owning Real Estate: Foreign corporations that own and rent out real estate in the US need to file the form.
- Branch Operations: Foreign corporations with branches or offices in the US must report the income from these branches.

However, for fiscal year corporations, the form is due by the 15th day of the fourth month after the end of the fiscal year (for example, if your fiscal year ends on June 30, your form is due by October 15).
Can I have an extension for filing Form 1120-F?
Yes, you can. Foreign corporations can request an extension to file Form 1120-F by submitting Form 7004, which grants a six-month extension.
What if I file late?
If you file late and owe tax, the IRS may impose penalties and interest.
The penalty for late filing is typically 5% of the unpaid tax for each month or part of a month that the return is late, up to a maximum of 25% of the unpaid tax.

What is ECI and what does it have to do with Form 1120-F?
Effectively Connected Income (ECI) is income earned by a foreign corporation that is linked to its trade or business activities in the United States.
ECI is crucial because it determines what income a foreign corporation must report and pay taxes on using Form 1120-F. Essentially, ECI is subject to US taxation.
How do you determine if a foreign corporation has effectively connected income (ECI)?
Here are the general criteria for ECI:
- Trade or Business in the US: The foreign corporation must be engaged in a trade or business within the US. This includes any regular and continuous business activities, such as selling products or providing services.
- Types of Income: ECI can include various types of income, such as:
- Income from US Sources: Income earned from sources within the US, like sales revenue or service fees.
- Passive Income: Certain types of passive income, such as dividends, interest, and royalties, can also be considered ECI if they are connected with the corporation’s US business activities.
- Asset-Use Test: Income is considered ECI if it is derived from assets used in the corporation’s US trade or business.
- Business-Activities Test: Income is considered ECI if the activities of the corporation’s US business are a material factor in realizing the income.
What are the deductions or credits available for foreign corporations on Form 1120-F?
Deductions
- Business Expenses: Ordinary and necessary business expenses related to the corporation’s US trade or business can be deducted. This includes:
- Salaries and wages
- Rent and utilities
- Office supplies and equipment
- Travel and entertainment expenses
- Depreciation: The cost of tangible property used in the US trade or business can be depreciated over its useful life.
- Interest Expense: Interest paid on business loans can be deducted, subject to certain limitations.
- Taxes: State and local taxes directly related to the US business operations can be deducted.
Credits
- Foreign Tax Credit: Foreign corporations can claim a credit for taxes paid to foreign countries on income that is also subject to US tax. This helps avoid double taxation.
- General Business Credits: Various business credits can be claimed, such as the Research and Development (R&D) Credit or the Investment Credit, if the corporation qualifies.
- Withholding Tax Credit: Taxes withheld on US-sourced income can be credited against the corporation’s US tax liability.
