For 2025, this article outlines the availability and practicalities of sole proprietorship—or an equivalent individual business status—for those considering business activities in Guernsey. The focus is on tax status, registration obligations, and the applicable rates according to the latest available government guidance.
Sole Proprietorship Status in Guernsey: Availability & Characteristics
Guernsey does not provide a dedicated sole proprietorship status with preferential tax or simplified registration regimes. Instead, individuals seeking to start a business can operate as sole traders. While you do not acquire a separate legal entity, you are required to fulfill all standard tax and compliance obligations applicable to privately owned businesses in Guernsey.

Business Registration & Taxation Requirements
Individuals running their own businesses in Guernsey are considered sole traders for all regulatory and fiscal purposes. While there is no distinct business status conferring simplified compliance or taxation, all sole traders are required to:
- Register formally with the Guernsey Revenue Service for tax purposes.
- Include business profits as part of their personal income for tax assessment.
- Adhere to the current flat income tax rate, set at 20% for 2025.
- Comply with mandatory social security registration and make all relevant contributions.
There is no regime in Guernsey that provides reduced rates, threshold-based allowances, or exemptions for small traders or new business founders. The standard requirements apply regardless of business size or income level.
Tax Compliance and Social Security Contributions
All profits made from sole trading must be declared to the Guernsey Revenue Service. The personal income tax rate for 2025 remains at 20%, with business earnings added to other sources of personal income for the overall tax calculation. Social security registration is also a legal requirement, ensuring that contributions are collected and credited correctly.
