Warning on the $10,000 Penalty: The IRS enforces a strict **$10,000 failure-to-file penalty** per year for each required Form 5471 that is omitted or filed late. The penalty accumulates monthly up to a maximum of $60,000 if not resolved after IRS notification.
Controlled Foreign Corporations (CFC)
When you move to the U.S. and establish U.S. tax residency (under green card status, H-1B, L-1, or the Substantial Presence Test), your overseas business is classified by the IRS as a **Controlled Foreign Corporation (CFC)** if U.S. shareholders own more than 50% of the total vote or value.
This has profound consequences for business owners from:
- Canada (CCPCs): Your Canadian-Controlled Private Corporation will likely lose its CCPC status under CRA rules because it is controlled by a Canadian non-resident. This triggers departure tax and eliminates the Canadian Small Business Deduction.
- United Kingdom (Ltd Companies): A UK private limited company controlled by a U.S. tax resident is treated as a CFC, requiring complex balance sheet disclosures.
- Germany (GmbHs): Subject to strict double-taxation credit rules and CFC look-through guidelines.
GILTI High-Tax Exception Calculator
Under the Tax Cuts and Jobs Act (TCJA), earnings of a CFC are subject to the **GILTI (Global Intangible Low-Taxed Income)** regime, which taxes undistributed profits as personal income. However, you can exclude income if the local corporate tax rate is at least **18.9%** (90% of the U.S. corporate tax rate of 21%).
Form 5471 Filer Categories
You must file Form 5471 if you fall into any of the following IRS filer categories:
| Category | Applies To | Filing Requirement |

| Category 2 | U.S. officers or directors of a foreign corporation in which a U.S. person acquires 10% or more ownership. | Acquisition filing. |
| Category 3 | A U.S. person who acquires a cumulative 10% or more ownership, or disposes of ownership to drop below 10%. | Acquisition/Disposition filing. |
| Category 4 | A U.S. person who controls a foreign corporation (owns >50% vote or value) for 30+ consecutive days. | Full balance sheet & transaction disclosure. |
| Category 5 | A U.S. shareholder who owns 10% or more of a Controlled Foreign Corporation (CFC). | Subpart F & GILTI details. |
IRC Section 962 Election: Individual CFC owners who do not qualify for the High-Tax Exception can elect under Section 962 to be taxed at corporate rates rather than personal tax rates, allowing them to claim indirect foreign tax credits (FTCs) to reduce their double taxation burden.
