Jersey invites joint-filing applications to 31 October; law says 30 September

Revenue Jersey's guidance now invites married couples and civil partners to apply to keep filing one tax return together under Independent TaxationGOV, publishing 31 October 2026 as its cut-offGOV — though the underlying law sets the statutory receipt deadline at 30 September in the year of assessmentJerseylaw.

From 1 January 2026 everyone in Jersey is taxed independently, with the first independent returns for 2026 filed in 2027. Couples who were in married or civil partnership taxation before 2022 may instead elect for joint filing. The previous guidance said the election deadline had passed with the next window opening from 1 August 2027; the rewritten page replaces that with a live application route running to 31 October 2026GOV. Because the statute requires receipt by the Comptroller no later than 30 September in the year of assessmentJerseylaw, a couple relying on the guidance date alone would file late for 2026Jerseylaw — the safe course is to treat 30 September 2026 as the operative deadline and the October date as the guidance page's published cut-off.

There are two ways to apply. Online, both partners must hold a digital ID — Yoti or JerseyMe — and both must have signed in to services.gov.je at least once to activate their accounts. Only after both partners have signed in does a Personal Income Tax Joint Filing Election tile appear in the dashboard for eligible couples. Without both digital IDs, the couple completes a paper joint tax return election form and posts it to Revenue Jersey, PO Box 56, Jersey, JE4 8PF.

The eligibility conditions are unchanged. The couple need to have married or formed their civil partnership before 1 January 2022, to have lived together without separation since 31 December 2021, to have both been ordinarily resident in Jersey in 2021 and continuously since, and not to have elected for independent taxation; they must not be separated or divorced. The election must be made by both partners, takes effect from the year of assessment 2026, and continues each year until one partner cancels it. The election is a written notice signed by both partners that nominates the responsible partner and permits the Comptroller to use both partners' income for the Article 99 exemption-threshold calculation; both partners agree to share their return information so each can discuss the tax position with Revenue Jersey, and each receives a separate tax bill and pays it personally. The Comptroller must accept a valid election unless a partner has an overdue return or unpaid tax.

One partner is nominated to file the single return and carries the compliance risk: the filing partner is responsible for late-delivery penalties and penalties for inaccurate information, as the election form confirms. Couples using a tax agent must both appoint the same agent for the joint return, with an authority-to-act section completed so Revenue Jersey can correspond with the agent.

Joint filing also simplifies the compensatory allowance — the allowance protecting couples who would otherwise pay more under Independent Taxation. Filing jointly puts all the couple's information in one return so the allowance can be calculated at once; couples filing separately should file at the same time, because the earlier filer is initially assessed without the allowance and re-assessed once the second return arrives.

Legal basis: Articles 16AA and 16AB of the Income Tax (Jersey) Law 1961 (inserted by the Income Tax (Amendment – Stage 2 of Independent Taxation) (Jersey) Law 2024), as reflected in Revenue Jersey's Independent Taxation guidance and joint tax return election form.
