In brief: The Government of Jersey has extended two key tax deadlines from 30 September to 31 October, giving islanders more time to opt into joint filing and to choose how they repay frozen 2019 tax bills. Take-up on both has been low, with only around 4,000 of 14,000 eligible couples having opted for joint filing so far.
The backstory: from Prior Year to Current Year
Before 2020, around 45,000 islanders paid income tax on a Prior Year Basis, meaning their bill was calculated on the previous year’s income rather than what they actually earned in the current year. In 2020, Jersey switched to a Current Year Basis, aligning the tax year with the year of earnings. Sensible enough in principle, but the transition created an awkward problem: what to do with the 2019 liability that sat in the gap between the two systems.
Rather than demanding immediate payment, the States agreed to freeze those 2019 bills and temporarily absorb the debt, a reasonable call given the financial pressures of the pandemic. The crucial detail, however, is that the liability was deferred, not written off. Some islanders now face paying back thousands of pounds in unpaid tax, and the clock is ticking on how they choose to do it.
Three ways to pay, and a default if you do nothing
Bailiwick Express reports that affected islanders have three options for settling their frozen 2019 bills. The outlet does not detail all three individually, but notes that those who do not actively choose an option will automatically be enrolled in a 17-year interest-free annual payment scheme. That default option may well suit many people, but the point is that it is a default: islanders who want a different arrangement need to act before 31 October.
Revenue Jersey’s decision to extend the original 30 September deadline reflects the reality that take-up has been relatively low. Whether that is down to islanders being unaware of the deadline, unconcerned about the default option, or simply putting it off is not clear from the source material. What is clear is that the extension gives people one more month to make an active choice rather than having one made for them.
Joint filing: a window closing for eligible couples
The second deadline extension concerns joint tax filing. From the 2026 tax year, everyone in Jersey will be taxed independently, each person responsible for their own return. However, islanders who were married or in a civil partnership and living in Jersey before 2022 may be eligible to continue filing a single joint return as a couple, even though they will still be taxed independently. Think of it as one form, two taxpayers.
So far, around 4,000 couples from a pool of 14,000 eligible pairs have opted in, meaning roughly 10,000 eligible couples have yet to make a decision. That is a significant proportion, and it is presumably why Revenue Jersey felt compelled to push the deadline back to 31 October. Couples who miss this window will presumably be required to file separately from 2026 onwards, so those who prefer the joint arrangement would be wise to act promptly.
