What Are CFC Rules?
CFC Rules are international tax anti-avoidance provisions under which resident shareholders are taxed on certain undistributed profits of controlled foreign entities, as national law defines.
Also known as: Controlled Foreign Company Rules, CFC Legislation.
How CFC Rules works
CFC Rules apply when a resident taxpayer controls a foreign company or permanent establishment whose profits face low taxation abroad, and the rules then add part of the foreign entity's undistributed income to the controlling shareholder's taxable base in the residence country, even though no dividend has been paid. Under the EU Anti-Tax Avoidance Directive, applied from 1 January 2019, control means more than 50 percent of voting rights, capital or profit entitlement, and low taxation means foreign corporate tax below the difference between the tax due under the Member State's system and the tax actually paid. Member States then include either listed categories such as interest and royalties, unless the controlled foreign company carries on a substantive economic activity supported by staff, equipment, assets and premises, or income from non-genuine arrangements, in proportion to the taxpayer's participation. The UK regime in Part 9A TIOPA 2010 charges only UK resident companies holding at least 25 percent of chargeable profits, while the US Subpart F model taxes United States shareholders, including individuals, owning at least 10 percent of a corporation more than 50 percent owned by such shareholders. Thresholds, income categories and exemptions therefore vary by jurisdiction, and some countries extend CFC Rules to resident individuals while others limit them to companies.
CFC Rules vs Place of Effective Management (POEM)
Unlike Place of Effective Management, which can make a foreign company itself tax resident where key management decisions are taken, CFC Rules leave the company non-resident and instead attribute part of the company's profits to the controlling shareholder.
| CFC Rules | Place of Effective Management (POEM) | |
|---|---|---|
| Who is taxed | The controlling shareholder in the residence country, on attributed profits | The company itself, as a resident of the country where effective management takes place |
| Trigger | Control threshold plus low foreign taxation and specified income or non-genuine arrangements | Location of key management and commercial decisions |
| Legal source | Domestic law, with an EU minimum standard in ATAD Articles 7 and 8 | Domestic corporate residence rules and treaty tie-breaker provisions |
Example
Illustrative example: A consultant resident in an EU Member State operates through a company resident in the same Member State, which owns all shares of a subsidiary in Country B. The subsidiary earns mainly royalties from licensing software, has no staff or premises in Country B and pays corporate tax well below the Directive's benchmark. Because the parent holds more than 50 percent and the low-tax test is met, the Member State's CFC Rules may add the subsidiary's undistributed royalty income to the parent's tax base in proportion to the participation, depending on how national law transposed Article 7. If the subsidiary instead employed developers and operated from its own office in Country B, the substantive economic activity carve-out could exclude the categorised income. Where the consultant holds the Country B company directly, the outcome depends on whether national CFC Rules reach individual shareholders.
Common misconception
Myth: Profits of a foreign company are taxed in the owner's residence country only once dividends are paid out.
Reality: Where CFC Rules apply, part of a controlled foreign company's undistributed profits may be taxed in the controlling shareholder's residence country before any distribution, subject to local thresholds and exemptions.
Frequently asked questions
What are CFC rules?
CFC Rules are anti-avoidance provisions under which a residence country taxes a controlling shareholder on certain undistributed profits of a low-taxed foreign company, with control, low-tax and income tests defined by national law.
Do CFC rules apply to individuals?
CFC Rules under the EU Anti-Tax Avoidance Directive and the UK Part 9A regime target companies, while the US Subpart F regime also reaches individual United States shareholders; other countries may extend CFC Rules to resident individuals under national law.
How do CFC rules affect digital nomads with a foreign company?
CFC Rules generally follow the shareholder's tax residence, so a foreign company owned by a nomad may face attribution in whichever country treats the owner as resident, subject to that country's control thresholds, income tests and exemptions.
What is the difference between CFC rules and Subpart F?
Subpart F is the United States version of CFC Rules, taxing United States shareholders owning at least 10 percent on specified income of a controlled foreign corporation, whereas CFC Rules is the generic term covering all national regimes.
