2024 Jersey Corporate Tax Return and Combined Partnership Notification
Jersey Corporate Tax Return
A corporate tax return is required in respect of any of the following:
- Jersey Incorporated Companies
- Foreign Companies (Tax Resident in Jersey by virtue of Management and Control)
- Foreign Companies (Trading in Jersey through a Permanent Establishment)
- Foundations
- Incorporated / Unincorporated Bodies
- Associations
When completing the Jersey Corporate Tax Return, you will be required to provide financial information such as turnover, accounting profits and taxable profits, as well as attach signed financial statements for the period under assessment.
The return will also require declarations to be made in respect of Jersey Economic Substance.
Combined Partnership Notification
A Combined Partnership Notification is required in respect of any of the following:
- Jersey General Partnerships
- Jersey Incorporated LP’s and LLPs
- Foreign LLP (with an Article 76E election)
Before submitting your Combined Partnership Notification, you must nominate a responsible partner. If you have submitted a responsible partner notification previously, you do not need to repeat this process, unless the responsible partner has changed.
When completing the Combined Partnership Notification, you will be required to provide financial information such as turnover, accounting profits, taxable profits and partner details.
As with the Jersey Corporate Return, a Combined Partnership Notification will also require declarations to be made in respect of Jersey Economic Substance.
There is currently no requirement to submit financial statements with a Combined Partnership Notification.
The 2024 Corporate Tax Return and the 2024 Combined Partnership Notification are due for submission by midnight on Sunday, 30th November 2025.
Any entity which fails to deliver the return by this deadline will be liable to a penalty of £300. Furthermore, if the return is not delivered within 3 months after the deadline will also be liable to an additional penalty of £100 for each month that the return remains undelivered up to a maximum of 9 months.
In the absence of a return, Revenue Jersey will raise a “default assessment”, which is a demand for payment based on estimated income for the year. If no return is submitted within a year of this assessment, the liability will stand unless the actual assessment is higher.
Even if you submit your return on time, you may still be subject to penalties if your submitted return is not true, complete, and correct. This means that any error or omission found in the return can attract a surcharge, even if it is accidental.
Our team at Grant Thornton are experts in Jersey tax and are available to help with all aspects of Jersey corporate and partnership tax.
