Guernsey tax for companies: 0% today, and the reform on its way
A Guernsey company pays 0% tax on most profit, with nothing deducted from dividends to owners abroad. Regulated finance pays 10%; Guernsey property and utilities 20%.
Two changes are approved but not yet law: a wider 10% band from 2027 and a 3% GST from early 2029.
Guernsey is in the middle of changing its tax system. On 2 October 2026 its parliament voted for a 3% GST from 2029 and a wider 10% band from 2027, and neither is law yet. Most pages ranking today don't mention either. Here's where things stand, and what reaches a company run from abroad.
Key takeaways
- The standard company rate is 0%; 10% for regulated finance; 20% for Guernsey property, utilities and big island retail.
- From 1 January 2027 the 10% band is set to widen to accountants, lawyers and estate agents. The law isn't made yet.
- Guernsey has no VAT or GST. A 3% GST is planned from early 2029, and must wait if household help isn't ready.
- Dividends to owners abroad carry no deduction, with proof they live elsewhere.
- The return is due by 30 November. Late costs GBP 300, then GBP 50 a day.
- Residents pay 20%, capped at GBP 160,000 on foreign income or GBP 320,000 in total.
Guernsey corporate tax rate: 0%, 10% and 20%
The three bands are set out in the Revenue Service's tax information for companies. The old exempt company status for ordinary businesses is gone. Exemption now only exists for investment funds, at GBP 1,600 a year.
0% for most companies; the exempt company is now only for funds.

Guernsey company tax residence
A Guernsey company is Guernsey resident unless it proves it's managed and controlled, and resident, in a place with a top company rate of at least 10%, or a treaty puts it there, and not to avoid tax. The Revenue Service's circular on company residence sets out the test.
- Board meets and decides in Guernsey
- Run from a country with no company tax, or under 10%
- Run from abroad, but that country doesn't claim it
- Run from a country taxing companies at 10% or more
- And tax resident there
- Then taxed there, at that country's rate
Run from a 10% or higher country and resident there, it can leave Guernsey's net.
Guernsey dividends: owners abroad and residents
| Shareholder | Deducted by the company |
|---|---|
| Lives outside Guernsey, with evidence on file | Nothing |
| Guernsey resident, from 0% profit | 20% |
| Guernsey resident, from 10% profit | 10% |
| Guernsey resident, from 20% profit | Nothing more |
Proof you live elsewhere, and the dividend goes out whole.
