Guernsey annual fees and filings: eight weeks that decide the year

Every Guernsey company files the same yearly return in the same eight or nine weeks, whatever its formation date. The Registry's annual validation guidance sets the window at 1 January to the last day of February, made up to 31 December. The one exception helps new companies. If yours is formed in December, the Registry doesn't expect a validation a few weeks later; your first one comes the winter after. The form for 2027 opens for drafting in early November 2026 and is filed online by the licensed provider or an authorised filer, with payment.

The Registry sorts companies into categories, and on its annual validation page the category sets the fee. A company owned from abroad almost always sits in the one for companies administered by a licensed corporate service provider, because that provider acts as its resident agent. Fees rose on 1 January 2026, and a further rise of about 4.3% is expected from 1 December 2026.

The figures after 1 December are our arithmetic on the announced rise, because the new table wasn't published when this page went up. You pay what the Registry's fee schedule actually charges, at cost. The return also asks whether the company holds high value assets over £5 million.

Until summer 2026 a late validation meant a letter and some discretion. Since 1 September 2026 the Registry's system issues the civil penalty for a late annual validation automatically, and the company is marked In Default on the register until it files. Under the Registry's civil penalties guidance, the penalty is paid within 28 days, and an appeal goes to the Court within 21 days. Pick when the validation went in.

The yearly validation is a snapshot. Between snapshots, the Registry expects to hear about people changes within two weeks, and those penalties are automatic too.

One more is worth knowing because it sits behind every foreign owned company: a Guernsey company must always have a resident agent. Without one it faces a £2,500 civil penalty and can be struck off. With us, the licensed provider fills that role every year.

Guernsey keeps company accounts off the public record altogether: the Registry holds no financial information on companies. That doesn't mean there are none. Under the Registry's guidance for directors, directors prepare accounts for each year and send them to the members within 12 months of the year end.

The audit is the part most people get wrong. It applies by default. Members can switch it off with a waiver passed by 90%, filed with the Registry's resolutions and waivers within 30 days, and it can run indefinitely. Pass it in the year before the one it covers, or for a new company in its first financial year. Large and regulated companies generally can't waive. Skipping an audit you needed is fined on the same scale as a late validation.

Most Guernsey companies pay tax at the standard 0%. They still file a return each year, for the calendar year, by 30 November of the next one, the date the Revenue Service gives in its notice to file for 2025: 2026 is due on 30 November 2027. A company with no local owners, no Guernsey staff beyond directors and no regulated income usually files under the simpler Certificate 3 route. The 10% and 20% rates only reach specific income, such as banking, fiduciary work, local utilities or Guernsey property. A late company return costs £300 on the Revenue Service's penalties page, then £50 a day, running from the date of the first penalty if the return isn't in within 30 days. No cap on the daily part is published there.

Some activities also carry economic substance rules: banking, insurance, shipping, fund management, financing and leasing, headquarters, distribution and service centres, pure equity holding and intellectual property. A company in those sectors shows Guernsey management, staff and premises through the tax return, and fines under regs 13 to 16 of the Income Tax (Substance Requirements) (Implementation) Regulations 2021 start at up to £10,000. A company trading online or selling services isn't on that list. See which applies to you.

A borderline case needs a Guernsey tax adviser's view.

The Registry's fee is the small part. The real cost of a Guernsey company run from abroad is the licensed provider who acts as resident agent, keeps the owner record, gives it an office and files for it. That sits inside our price.

A company that stays In Default, or loses its resident agent, is liable to be struck off by the Registrar, who publishes the names on an involuntary strike off notice first. Coming back is possible, but slow and costly.

Closing on purpose, by striking off or winding up, is far cheaper, and in Guernsey it can be free.
