Revenue Service publishes standard 0%, intermediate 10% and higher 20% rates. The intermediate categories include specified financial/fiduciary, custody, fund administration, investment, compliance and aviation-registry activities. Higher-rate categories include regulated trading, hydrocarbon/gas supply, large retail above the stated £500,000 taxable-profit threshold, Guernsey property income/development and specified cannabis/controlled-drug business. Classify the income stream, not merely the entity's name. Company guidance, income tax rates.
The published tax-reform programme describes changes from 2027, including prescribed professional services. Do not backdate them to 2026 or assume a policy announcement alone establishes the final enacted scope. Reform timetable.
Rate illustration: established ordinary taxable income £100,000 at 0% produces £0 corporate income tax; separately established Guernsey rental taxable income £20,000 at 20% produces £4,000. This does not waive returns, distribution tax, substance obligations or minimum-tax review. Do not use this split if a rule requires the company's wider profit base to be taxed at another rate.
The 2025 company return is due 30 November 2026. Annual online filing and accountant-certified accounts are required; audit exemption does not itself remove tax certification. Use the correct return certificate and retain the qualification/authority of the certifying accountant. Company guidance.
Screen the relevant activities and document direction/management, people, premises, expenditure and local core income-generating activities. Pure equity holding and high-risk IP require their own tests. Economic substance guidance.
A distribution from income taxed below 20% to a Guernsey-resident beneficial member requires a separate tax/reporting calculation. Keep evidence of non-residence before treating a payment to a non-resident member as outside the stated distribution charge. Loans are not automatically exempt alternatives. Company distributions and qualifying loans.
This is not a company-incorporation checklist, document-duty calculation, treaty-rate opinion or Pillar Two determination. Complete the entity-specific registration, ownership, audit, accounts and sector requirements separately before the country is marked covered.
General tax and accounting reference material only. These drafts have not been professionally attested. A qualified professional in the relevant jurisdiction must check the facts, current law, elections and deadlines before anyone files, pays or acts on an output.
