On 17 July 2026, the Bermuda Corporate Income Tax Agency (CITA) released various forms and instructions relating to the Bermuda corporate income tax (CIT) return filing process for in-scope taxpayers under the Corporate Income Tax Act 2023 (CIT Act). The materials released include the CIT online return, the standard CIT return schedules and related instructions, and the simplified CIT return schedules and related instructions. The returns will be the first CIT returns filed following the introduction of CIT.
The CIT return is due on the last day of the 10th month following the end of the fiscal year to which the return relates, subject to adjustment where that day is not a business day in Bermuda. The 2025 return will be due 2 November 2026 for calendar year taxpayers.
Bermuda constituent entity (BCE) groups (comprising one or more BCEs of an in-scope multinational enterprise (MNE) group) are required to file a CIT return for each fiscal year beginning on or after 1 January 2025. Each CIT return filing comprises the CIT online return and either the simplified CIT return schedules (to the extent that the BCE group is a qualifying de minimis BCE group that meets the requirements described in the simplified CIT return schedule instructions, and the filing BCE has chosen to file those schedules) or the standard CIT return schedules (in all other cases).
The standard CIT return schedules are expected to be relevant for most in-scope taxpayers that do not qualify for, or do not elect to use, the simplified return process. The instructions state that the standard CIT return schedules are intended to support the determination of the aggregated amounts required to be reported in the CIT online return and to provide the CITA with further information regarding the derivation of those amounts.
As a summary, the following forms and instructions were released:
