Sole trader or company? in

What each costs you in tax, what each costs to run, and the one question that usually decides it: will you keep money in the business?

Herm has no government of its own: it is owned and administered by the States of Guernsey, which have leased the whole island to one tenant company since 2008 — so Guernsey’s laws, taxes and registries apply there.

Income tax and company tax are checked; self-employed social security is still being researched.

Most Guernsey companies pay 0%. A Guernsey resident pays 20% income tax above the personal allowance — £15,200 in 2026 — on profit as a sole trader, or on what the company pays them, which the company deducts at 20%.

  2. As a companyYouthe Revenue Service

    A company registers with the Revenue Service too, pays 0%, 10% or 20% depending on its business, and files an online return every year. Where its income was taxed at 0%, it deducts 20% from what it distributes to a Guernsey resident.
