What is Form 5471?

How it works

Form 5471 is filed annually with Form 1040 (for individuals) or 1120 (for entities). Five categories of filer trigger it:

• Category 1: US shareholders of a Section 965 specified foreign corporation (transition tax legacy).
• Category 2: US officers or directors who become aware of a US person acquiring a 10%+ stake.
• Category 3: US persons who acquire enough stock to cross the 10% threshold or dispose of enough to fall under it.
• Category 4: US persons who control (>50%) a foreign corporation for at least 30 consecutive days during the year.
• Category 5: 10%+ US shareholders of a Controlled Foreign Corporation (CFC) — the broadest category in practice.

Each category requires a different bundle of schedules. Categories 4 and 5 attach the full set: income statement (Schedule C), balance sheet (F), earnings & profits (J, P), Subpart F inclusions (Q), shareholder transactions (M), and others depending on facts. Categories 1, 2 and 3 file streamlined versions.

Examples

• US founder of a Cayman company. A US citizen owns 100% of a Cayman exempted company that holds his app-store revenue. Even if the Cayman company has zero US-source income, he files Form 5471 every year as both a Category 4 (sole shareholder = control) and Category 5 (10%+ owner of a CFC) filer. Subpart F and GILTI inclusions follow on his Form 1040.
• Joint venture across the border. A US tech company holds 35% of a UK Ltd; two UK partners hold the rest. The US company is a Category 5 filer because the UK Ltd is a CFC under the constructive-ownership attribution rules. Even at minority position, the 5471 schedule covers earnings, transactions and dividends.

Common mistakes

• Assuming "small foreign company, no income, no filing". The 5471 is an information return — it doesn't depend on income. A dormant foreign LLC with $0 revenue still costs the owner a $10,000 penalty per year if missed.
• Treating a foreign LLC as automatically disregarded. A foreign LLC defaults to corporation classification under the check-the-box rules; to be disregarded or partnership-taxed, you affirmatively file Form 8832. Without that election, you owe Form 5471, not Form 8865.
• Mismatching the category. Filing as Category 3 when you're actually Category 5 means missing schedules, which the IRS treats as a failure to file. Worth a tax advisor reviewing the category logic each year.
• Forgetting the dual-status arrival year. New US tax residents who already owned foreign corporations before moving to the US frequently miss the first 5471 in their year of arrival — the form is owed for the resident portion of the year.
