What is a Jersey Personal Tax Return?
When we talk about a Jersey personal tax return, we mean the information that individuals must submit to Revenue Jersey, outlining their income, deductions, and allowances for the year of assessment (January to December). As a taxpayer, it’s your responsibility to make sure the information is complete and accurate.
If you’re unsure what counts as taxable income, Revenue Jersey’s guidance includes employment income, pensions, property rentals, and investment income. Exemptions, such as child allowance or married couple’s relief, may also apply and must be claimed through the return.
Key Deadlines and How to Avoid Late Filing Penalties
The Jersey tax years runs from 1 January to 31 December. The due date for filing personal tax returns is 31 July in the year following the relevant tax year – but there’s an important distinction depending on how you choose to file.
- If you are filing a paper tax return, it should have been received by Revenue Jersey by 31 May.
- If you file online, you have until 31 July.
The earlier paper deadline reflects the extra time needed to process and assess paper forms compared to digital submissions. If you miss these deadlines, you could face the following late filing penalties:
- A £300 initial fine (or the amount equal to your tax if your assessment is less than £300).
- An additional £50 per month (up to £450 total) if your return is still outstanding after three months.
Whether you’re expecting a refund or not, your obligation to file remains. The best way to avoid problems is to plan ahead, register for online filing, and start gathering your records early.
Submitting Your Jersey Tax Return
You can file your tax return in one of two ways:
- Online, using Revenue Jersey’s online tax return portal at gov.je
- By paper, using the form issued by Revenue Jersey
It can also be very helpful to engage a tax advisor to file on your behalf (by 31 July)
Most taxpayers are now encouraged to submit online, as it’s quicker, provides immediate confirmation of receipt, and often results in faster assessments. If you haven’t signed up before, you’ll need a onegov account and your Tax Identification Number (TIN) to access the service.
The steps for submitting a Jersey personal tax return are as follows:
- Log into your onegov account
- Select “File my tax return”
- Complete all sections, including employment income, pensions, rental properties, and any other income
- Make any relevant claims for allowances and deductions
- Review your return carefully before submitting
- Download a copy for your records or view previous tax returns through the portal

Common Mistakes to Avoid on Your Personal Return
Even those who have completed a tax return many times can find themselves making avoidable errors when it comes to completing their Jersey personal tax return.
In our experience, some of the most common issues include missing the filing deadline – which remains the single biggest trigger for penalties being imposed.
Others frequently forget to declare all sources of income, particularly dividends, rental income or overseas pensions, which can lead to incorrect assessments. We also see individuals omitting to declare UK income because it may have already been taxed in the UK or mistakenly claim allowances they’re not entitled to, or fail to update Revenue Jersey following changes in their circumstances, such as a change in marital status or the birth of a child.
Another area that’s often overlooked is recordkeeping. Without supporting documents like interest certificates or rent statements, it’s harder to validate your return if questions arise later. The good news is that these personal tax pitfalls can usually be avoided with a bit of forward planning, and by seeking the right advice early in the process.
Tips to File More Confidently and Correctly
Filing your Jersey personal tax return doesn’t need to be daunting but it does require care. In our experience, a few practical habits can make the process much easier, and reduce your chances of needing to make corrections later on.
Start by gathering all your documents well before you plan to file. While you won’t need to submit them alongside your return, you should still keep them (at least six years in the case of income earned by self-employed individuals) in case Revenue Jersey asks for supporting information or opens an enquiry. This includes payslips, pension advice letters, receipts for deductible expenses, bank statements, loan interest certificates, your child’s social security number, and childcare certificates.
Once you’re ready to complete your return, take your time. Carefully check each section before submitting, especially the details about your residency and marital status. If you’re claiming the married or civil partnership exemption threshold, make sure you’ve ticked the appropriate box. The income you declare should match your supporting paperwork. For example, your employment income should be the same as the gross taxable figure on your payslips.
Equally important is being realistic about what you can claim. Deductions and allowances, like child allowance or business expenses, should only be included if you’re fully eligible, for example, if a business expense is incurred wholly and exclusively for the purpose of the business.
Here are a few of our key Jersey tax filing tips:
- Keep financial documents in one place throughout the year
- Double-check all income and declared deductions
- Make sure your status and personal details are up to date
- Check and only claim for allowances and/or expenses you are entitled to
- Review everything before clicking submit
