Controlled Foreign Company (CFC) Charge Calculator

A CFC is a non-UK resident company controlled by a UK resident company (directly or indirectly owning >50% of voting rights, income, or capital). The UK CFC rules (TIOPA 2010 Part 9A) tax UK-resident controllers on their share of CFC profits that have been artificially diverted from the UK.

Before the CFC charge applies, profits must pass through the 'gateway' — they must be artificial diverted profits that would otherwise have been taxed in the UK. This is assessed by applying specific chapters: finance income, trading income, IP income, and insurance. Not all CFC profits are caught.

Five key exemptions: (1) Exempt period — first 12 months of CFC status, (2) Low profits — accounting profits under £500k or passive income under £50k, (3) Low profit margin — accounting profits under 10% of expenses, (4) Sufficient local substance — genuine local management and operations, (5) Excluded territories — countries on HMRC's approved list (high tax jurisdictions).

HMRC periodically updates the excluded territories list. Countries generally included (where local management is genuine) are high-tax jurisdictions where UK tax avoidance via CFCs is unlikely. The list includes Germany, France, USA, Australia, Canada, and many others — but not traditional tax havens.

The charge equals the UK Corporation Tax rate applied to the chargeable profits of the CFC, less a credit for foreign tax already paid on those profits. UK shareholders holding 25%+ of the CFC pay the charge in proportion to their holding.

The rules aim to catch artificial diversion. A CFC with genuine local trading activity, real employees, and local management of a business that is commercially driven by non-UK activities is less likely to have its profits attributed. The 'gateway' test is key.

From 2024, the UK implemented Pillar Two (global minimum tax) — a qualified domestic minimum top-up tax ensuring large multinationals pay at least 15% effective tax rate. For UK groups, Pillar Two may apply alongside or instead of CFC charges, depending on the specific facts.

Yes — companies can challenge HMRC's application of the CFC rules through normal appeal procedures. Advance rulings from HMRC are available for complex CFC arrangements. Transfer pricing APAs can also cover CFC-related profit attribution.
