Thousands of late tax returns could see around £1.2 million-worth of penalties issued after last month’s filing deadline.

Revenue Jersey said it had received more than 63,000 returns for the 2025 year of assessment by the 31 July deadline, against around 67,000 it expects to receive in total.

Anyone who missed the deadline faces an immediate £300 late-filing penalty, with further penalties applying if their return remains outstanding.

If around 4,000 taxpayers are ultimately liable, that could equate to approximately £1.2 million in initial penalties.

Express has asked Revenue Jersey to confirm the exact number of returns currently outstanding, but the department was unable to do so.

Those who have not filed will also begin receiving ‘Default Assessments’ from Revenue Jersey.

Do it “as soon as possible”

These are estimates of the tax a person owes and remain legally due and payable unless they are subsequently replaced by an assessment based on a completed tax return.

Comptroller of Revenue Richard Summersgill urged anyone who had missed the deadline to act quickly.

“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,” he said.

Meanwhile, Revenue Jersey said there had been continued growth in the number of Islanders choosing to submit their returns digitally.

Online filing numbers “encouraging”

Some 58.4% of the more than 63,000 returns received by the deadline were filed online – an increase of four percentage points compared with last year.

Mr 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.”
