Controlled Foreign Company Rules CFC

Stands for: Controlled Foreign Company

Anti-deferral tax rules that attribute the passive or low-taxed income of a foreign subsidiary to its domestic parent, even without distribution.

Definition

What it is

Controlled Foreign Company (CFC) rules are anti-avoidance provisions that prevent multinational groups from parking passive or highly mobile income in low-tax foreign subsidiaries. If the foreign entity is controlled (typically more than 50% by the domestic parent or related parties) and meets a low-tax test, certain categories of its income are attributed to the parent and taxed currently, regardless of whether profits are distributed.

Common designs

- **Categorical (transactional) approach**: only specific tainted income (passive interest, royalties, dividends, certain related-party services) is attributed - used by the US Subpart F regime.
- **Entity approach**: all income of a low-taxed foreign subsidiary is attributed - used by parts of the EU ATAD-aligned regimes.
- **Mixed approach**: many EU members combine the two after ATAD I.

The US adds the Global Intangible Low-Taxed Income (GILTI) regime on top of Subpart F. The EU Anti-Tax Avoidance Directive (ATAD) imposes a minimum CFC standard. The UK has its own gateway-based CFC rules, and India runs the Place of Effective Management test plus specific anti-avoidance provisions.

Why it matters

CFC rules can completely undo the cash-tax benefits of a foreign holding or IP company.

When you'll encounter it

You will encounter CFC rules whenever you consider an offshore IP-holding entity, a captive insurer, an intra-group financing company, or any subsidiary in a low-tax jurisdiction. They also surface during M&A diligence, where the buyer scrutinises whether prior structures created CFC inclusions.

FAQ

Do CFC rules apply to small groups?

Yes, in many jurisdictions. The US GILTI regime, for instance, applies to any US shareholder owning 10% or more of a controlled foreign corporation, regardless of group size.

What income is usually targeted?

Passive income such as interest, dividends, royalties, certain capital gains, and related-party service fees, especially when taxed below a defined threshold abroad.

Does Pillar Two replace CFC rules?

No. Pillar Two coexists with CFC regimes. Some countries are recalibrating their CFC rules now that a 15% global minimum tax applies, but CFCs remain in force.
