Guernsey Deadlines & Penalties

On March 10, 2026, the Guernsey Revenue Service published a bulletin (2026/02) providing the FATCA and Common Reporting Standard (CRS) reporting deadlines and outlining the penalties associated with late reporting.

Deadlines

FATCA and CRS reporting for Y2025 data is due on or before Tuesday, June 30, 2026. There is a delay of potentially weeks between an entity registering in the U.S. Internal Revenue Service (IRS) FATCA portal and the entity appearing on the IRS FFI List. The list is static, and the IRS updates it the first of each month. However, the updated list has a cut off period of approximately five days before the end of the previous month. It is important that entities do not delay in registering in the IRS FATCA portal in order to avoid issues with reporting through Guernsey’s IGOR system.

TIN Reporting

The relief on FATCA reporting of TINs on pre-existing accounts continues based on rules outlined in the Guernsey bulletin and the previously issued IRS Notice 2024-78.

Penalties

Any entity which fails to meet the June 30, 2026 deadline, will be subject on July 1, 2026 to a penalty of £300 for each missing FATCA and/or CRS report. Thereafter, each missing report will incur a daily penalty of £50 for the following 30 days. The daily fine for reports which have not yet been filed will then increase per the following schedule:

• From 2 August 2026 £100 per day

• From 1 September 2026 £250 per day

• From 1 October 2026 £500 per day

• From 1 November 2026 £750 per day

• From 1 December 2026 £1,000 per day
