Can I Claim Office Rent and Co-working Space as a Business Expense in Guernsey?
Yes — office rent, co-working memberships and business premises costs are fully deductible against Guernsey corporate income tax as ordinary business expenses. The cost must be wholly and exclusively incurred for the purposes of the trade.
What Revenue Service, States of Guernsey says
The States of Guernsey Revenue Service allows deduction of business premises costs under the general rule that expenses incurred wholly and exclusively for the purposes of the business are deductible in computing trading profits.
When you can claim
- Annual office lease in St Peter Port or elsewhere in Guernsey
- Co-working or hot-desk memberships with a clear business purpose
- Business rates (Guernsey paroisse rates or rates levied by the Department of the Environment)
- Service charges, building insurance and maintenance on business premises
- Remote worker using a dedicated home office room (proportionate claim based on floor area)
When you cannot claim
- Personal residential accommodation costs (no dedicated business use)
- Mixed personal/business home-office costs where the room is not exclusively used for business
- Residential property acquisition costs (capital, not revenue expenditure)
- Penalties and fines related to premises
Good to know
Pro tip: Guernsey has no VAT, so office costs are a clean deduction with no VAT recovery to track. Keep the lease agreement, service charge statements and bank evidence. For home offices, document the room's exclusive business use and calculate the proportion of total floorspace.
