Jersey Business Manager works out your ITIS, your contributions and your quarterly figures, then prepares a summary for your accountant to review. Review time depends on your records and circumstances.
Runs on your own computer. No account to create, and once you have the file it needs no internet: nothing you enter is ever uploaded.
Jersey accountants describe their own work as turning a pile of invoices, receipts and bank statements into an organised set of books. That pile is the expensive part - and it is the part you can hand over already done.
Use the parts you need. If you have no staff, the payroll screen simply sits there unused.
Professional invoices with your own details, numbered automatically, ready to print or save as PDF from your browser.
Your figures arranged the way Jersey asks for them, with every deadline in front of you.
Enter each employee's effective rate once. Every month it works out the rest.
Four minutes, recorded from the real program with both example companies loaded. No mock-ups and no promises - this is the thing itself, at the pace you would actually use it.
One file. Save it in a folder on your computer.
Double-click. It opens in Chrome or Edge. Nothing to install.
Everything works. Long enough to run it alongside your current system and check it agrees.
If it earns its place, activate it. Your data stays exactly as it was.
It does not replace your accountant. Depending on your size and turnover, Revenue Jersey may require accounts prepared by a qualified accountant. What changes is what you hand them: organised figures instead of a shoebox.
It does not file anything for you. You copy the figures onto the real return on gov.je. You stay in control, and you stay responsible for what you submit.
It is not a shared system. One computer, one person at a time. If two people need to be in the books at once, this is not the right tool and I will tell you so.
Paid once a year. Renewal includes the January update, when Jersey revises its rates and thresholds.
On your computer, and nowhere else. There is no account to create and no server holding your data. For payroll that matters: your staff's salaries and Social Security numbers never leave the building.
Those are good at bookkeeping but they are not built for Jersey. They will not produce your CER or work out ITIS at each employee's effective rate. It can prepare records for use alongside your bookkeeping software. It does not replace a full accounting system or professional review.
For your first two or three months, run it alongside however you do payroll now and compare. Once the numbers agree, you can rely on it. That is the sensible way to adopt any payroll system, and it is what I recommend to everyone. It is also exactly why the free trial is three months and not one: you should be able to finish that comparison before you are asked to pay for anything.
Then you use 22%, the default rate Revenue Jersey requires until they provide one. The program prompts you for this.
Jersey revises its contribution limits and thresholds each year. Your renewal includes the updated version, so your calculations stay correct.
The program stops letting you carry on, but nothing is deleted. Your records sit exactly where they are and come straight back if you activate again. You can also export everything at any time.
Recommended: install the web app, keep its icon and use it in its own window. Three months free; no payment card required.
Open in Edge or Chrome, choose Install, then create your desktop or taskbar shortcut. Your business records stay in this browser profile; keep exported backups.
Download the program instead — one standalone HTML file, if you would rather not install.
Nothing is deleted. Your invoices, staff and records sit exactly where they are, and come straight back when you enter a licence code.
You can export your records even after the trial expires. If you stop using the app, keep your backups before uninstalling or clearing browser data. There is no subscription to cancel.
Built here, for the rates, thresholds and deadlines this island actually uses - not a UK program with the numbers changed. Every figure comes from what Social Security and Revenue Jersey publish, and it is updated each January when they change.
