Revenue Jersey received more than 63,000 tax returns by the 31 July filing deadline, with 58.4% submitted online, an increase of four per cent compared to last year. The increase follows continued work to encourage more Islanders, particularly new taxpayers, to use online services.
Revenue Jersey expects to receive around 67,000 returns for the 2025 year of assessment.
Comptroller of Revenue Richard Summersgill said: "It's encouraging to see more Islanders choosing to file their tax returns online, with almost 60% of returns now submitted digitally.
"Online filing is quicker and more convenient for taxpayers. It also allows Revenue Jersey to process returns more efficiently and provide a better service to Islanders. I'd like to thank everyone who filed on time, particularly those who used online filing for the first time this year."
Revenue Jersey will now begin issuing Default Assessments to Islanders who have not submitted a tax return. These estimated assessments remain legally due and payable unless replaced by a completed tax return.
Anyone who missed the deadline will face an immediate £300 late-filing penalty, with further penalties applying where returns remain outstanding for longer.
Mr Summersgill added: "Anyone who has not yet filed their return should do so as soon as possible to avoid additional penalties and ensure their tax assessment is based on their actual circumstances."
Guidance on filing outstanding returns is available at Revenue Jersey.
