Remote Working From the Isles of Scilly: Tax Basics for 2026/27
Working remotely from the Isles of Scilly doesn't change your UK tax position, but it does affect working-from-home relief, self-employed travel claims and broadband costs in 2026/27.
Quick answer
Working remotely from the Isles of Scilly doesn't put you in a special tax category — the same national Income Tax, National Insurance and expenses rules apply as anywhere else in England. What genuinely differs is the practical cost base: broadband, freight and travel to the mainland are all more expensive, which flows through into a bigger (but entirely normal) self-employed expenses claim, not a special island relief.

If your employer is based on the mainland and lets you work from Scilly full-time, the standard working-from-home tax relief test applies: relief is only available if your employer requires homeworking and doesn't already cover the costs, via a specific HMRC exemption for homeworking arrangements. Choosing to live somewhere remote for lifestyle reasons, with your employer's office notionally still your base, doesn't itself unlock extra relief.
Self-employed islanders
A self-employed person running a business from home on Scilly can claim a fair proportion of household running costs — heating, electricity, broadband, insurance — apportioned to business use, either via HMRC's simplified flat rates for hours worked from home, or by calculating actual costs and applying a business-use percentage. Because islands like Scilly typically have higher delivered fuel costs and premium broadband/satellite connectivity charges, the actual-cost method can produce a meaningfully larger, and entirely legitimate, deduction than the flat rate.

Genuine business trips — visiting a mainland client, supplier or professional adviser — are deductible travel costs, whether by the Scillonian ferry or the Skybus service. Regular travel to one fixed mainland office that counts as your permanent workplace is ordinary commuting and isn't deductible, exactly as it would be anywhere else in the UK.
Bottom line
Tax law doesn't have an "Isles of Scilly" chapter — it applies the same national rules, but the underlying costs of island life mean a carefully kept expenses record, using actual costs rather than flat-rate shortcuts, usually produces a fairer result.

Frequently asked questions
Does living somewhere remote like Scilly change my income tax rate?
No. Unless you're a Scottish taxpayer, everyone in England, Wales and Northern Ireland pays the same UK-wide Income Tax rates and bands, regardless of how remote their home is. There's no geographic Income Tax variation for the Isles of Scilly.
Can I claim working-from-home tax relief if I'm employed remotely from Scilly?
Employed home workers can only claim the flat-rate working-from-home tax relief if their employer requires them to work from home and doesn't already reimburse the costs — the same national test applies everywhere, not a special island rule.
Can a self-employed islander claim more generous home-office expenses?
The self-employed can claim a proportion of household running costs (heating, broadband, insurance) based on business use of the home, using either simplified flat rates or actual cost apportionment — the calculation method is the same UK-wide, though genuinely higher island utility costs simply feed through as higher actual expenses if that method is used.
Are ferry or helicopter travel costs to the mainland for business trips deductible?
Yes, where the trip is genuine business travel — for example to see a mainland client or supplier — rather than ordinary commuting to a single permanent workplace. The unusually high cost of Scilly transport links doesn't change the deductibility test, only the size of the deductible amount.
Does the Isles of Scilly have a separate Council Tax authority?
Yes — the Council of the Isles of Scilly is a unitary authority responsible for setting its own Council Tax rate, separate from Cornwall Council, even though the islands are geographically close to the Cornish mainland.
