14.3. Calendar of Important Compliance Events

Tax Year

The tax year is the calendar year, but companies are permitted to adopt any other 12-month period as the tax year.

Tax Return Filing

Companies are required to file their annual tax returns by 30 November. Subject to certain conditions, taxpayers may be authorized to file simplified tax returns.

Where a resident company extends loans to its individual resident beneficial members and such loans are still outstanding, the company will be required to file quarterly or monthly returns.

Guernsey has extended the deadline for filing annual tax returns for the tax year 2020 from 30 November 2021 until 7 March 2022 (earlier extended until 28 February 2022). Failure to file the annual tax return by the extended deadline will attract penalties.

Tax Payments

Tax is payable in two instalments on 30 June and 31 December each year.

Availability of E-Filing

It is mandatory for all Guernsey companies to file their tax returns electronically on https://eforms.gov.gg.
