The headline figure: GST is 5%
Jersey applies a single standard GST rate of 5% — far lower than UK VAT at 20%. Registration becomes compulsory once your taxable turnover exceeds £300,000 in any rolling 12-month period. Below that, you can still register voluntarily.
If you have moved a business to Jersey from the UK, or you are setting up here for the first time, the tax landscape can feel reassuringly light. Jersey is a Crown Dependency that sets its own taxes — it is not part of the UK or the EU — and the island has deliberately kept its consumption tax low and broad. The currency is sterling, the language is the same, but the rules are genuinely different.
Goods and Services Tax, or GST, is the Jersey equivalent of VAT. It is charged on most goods and services supplied in the island, collected by registered businesses, and paid over to Revenue Jersey. In this guide we walk through what GST is, how it compares to the UK system you may be used to, exactly who has to register, how the quarterly return cycle works in practice, and the avoidable mistakes that land small businesses with corrections and interest.
What GST Actually Is
GST is a tax on consumption. Each registered business in the supply chain charges GST on what it sells (output tax) and reclaims the GST it pays on its own purchases (input tax). The net difference is what you hand over to — or, occasionally, reclaim from — Revenue Jersey each quarter. The ultimate cost falls on the final consumer, not the business, which is why GST is described as a "pass-through" tax.
In plain terms
You collect 5% from your customers, you reclaim the 5% you were charged by your suppliers, and you pay Revenue Jersey the difference. Your business should be financially neutral on GST — you are essentially a tax collector for the Government of Jersey.
Most goods and services are "standard-rated" at 5%. Some categories are treated differently:
- Zero-rated supplies — GST charged at 0%, but you can still reclaim input tax (for example, certain exports)
- Exempt supplies — no GST charged and no input tax reclaim (for example, some financial services and dwelling rentals)
- Outside the scope — transactions that GST does not touch at all
The distinction between zero-rated and exempt matters more than it first appears. A zero-rated business still reclaims its input tax; an exempt business cannot. Getting your supplies classified correctly is one of the most valuable things a bookkeeper can do for you, and you should always confirm the current treatment of your sector with Revenue Jersey at gov.je.
GST vs UK VAT: The Key Differences
If your only experience of consumption tax is UK VAT, it is worth resetting your expectations. The two systems share the same basic input/output mechanism, but the headline numbers and the day-to-day burden are very different.
| Feature | Jersey GST | UK VAT |
|---|---|---|
| Standard rate | 5% | 20% |
| Reduced/multiple rates | Single rate | 5% & 0% bands |
| Registration threshold | £300,000 | Different UK figure |
| Authority | Revenue Jersey | HMRC |
| Typical return cycle | Quarterly | Quarterly |
Figures are indicative. Always confirm the current GST rate and registration threshold with Revenue Jersey at gov.je before relying on them.
The practical upshot is that GST adds far less to your prices and far less administrative weight than UK VAT. A 5% rate is much easier to absorb or pass on, and a single rate removes the perennial UK headache of deciding whether something is standard, reduced or zero-rated. That said, the lower numbers can lull owners into treating GST casually — and casual treatment is exactly where errors creep in.
Who Must Register for GST
Registration is compulsory once your taxable turnover exceeds £300,000 in any rolling 12-month period. "Rolling" is the word small businesses most often misread — it does not mean a fixed calendar or financial year. You must look back over the most recent twelve months at the end of every month, and look forward to whether you reasonably expect to cross the threshold in the coming thirty days.
Two tests to watch every month:
The historic test (have my taxable supplies over the last 12 months exceeded £300,000?) and the forward-look test (am I about to in the next 30 days?). Crossing either obliges you to register. A single large contract can tip a growing business over the line unexpectedly.
If you are below the threshold you can still choose to register voluntarily — useful if most of your customers are themselves GST-registered businesses who can reclaim the tax, or if you incur significant GST on your own purchases and want to recover it. Voluntary registration is covered in detail in our companion guide on the registration threshold.
Compulsory Registration Threshold
£300,000
Taxable turnover in any rolling 12-month period. Cross this line and you must register with Revenue Jersey — late registration can mean back-dated GST you may not be able to recover from customers.
How Quarterly Returns Work
Once registered, you account for GST in regular periods — typically quarterly. For each period you total the GST you charged on sales, total the GST you paid on eligible purchases, and submit the net figure to Revenue Jersey, paying any balance due by the deadline. The process is straightforward when your bookkeeping is current, and miserable when it is not.
A clean quarterly cycle looks like this:
- Record every sales invoice with the GST element shown separately
- Keep every purchase invoice that shows GST you have been charged
- Reconcile your records to your bank statements before you file
- Submit the return online and pay any GST due by the deadline
- Set the cash aside as you go so the payment never comes as a shock
The single most useful habit is to treat the GST you collect as money that was never yours. Move it into a separate account, or at least ring-fence it mentally, so that when the return falls due you are simply transferring funds you already held rather than scrambling to find them. Check current filing and payment deadlines on gov.je, and see our deadlines guide for the wider compliance calendar.
Common Filing Mistakes
Most GST problems are not exotic — they are the same handful of errors repeated across hundreds of small businesses. Knowing them in advance is the cheapest insurance you will ever buy.
The errors that cost real money
Reclaiming input tax without a valid invoice, missing the registration threshold and filing late, mis-classifying exempt supplies as standard-rated (or vice versa), and spending the GST you collected so it is not there when the return falls due.
- Forgetting that the £300,000 test is rolling, not annual, and registering too late
- Claiming back GST on purchases with no proper GST invoice to support it
- Treating GST collected as available cash flow and coming up short at filing time
- Mixing personal and business purchases so input tax claims cannot be substantiated
Almost every one of these traces back to bookkeeping that has fallen behind. Keep your records current and reconciled and the quarterly return becomes a ten-minute confirmation rather than a frantic reconstruction of three months of transactions.
Keeping the Right Records
Jersey businesses are required to keep their accounting records for at least six years. For GST purposes that means retaining the documents that prove both the tax you charged and the tax you reclaimed — because if Revenue Jersey reviews a return, the burden of evidence sits with you.
- Copies of every sales invoice showing GST charged
- Purchase invoices and receipts supporting every input tax claim
- Records of zero-rated, exempt and out-of-scope supplies
- Bank statements and reconciliations tying it all together
Good record-keeping is not bureaucracy for its own sake — it is what lets you reclaim every penny of input tax you are entitled to, defend your figures if questioned, and sleep soundly at quarter end. This is precisely the work a bookkeeper takes off your plate.
Frequently Asked Questions
Is Jersey GST the same as VAT?
Mechanically it works in a very similar way — you charge it on sales, reclaim it on purchases, and pay the difference. But it is a separate Jersey tax administered by Revenue Jersey, not HMRC. The standard rate is 5% rather than the UK's 20%, and there is a single rate rather than the UK's multiple bands. Jersey is a Crown Dependency and sets its own taxes.
Do I charge GST to customers outside Jersey?
It depends on where the supply is treated as taking place and whether it qualifies as an export or a zero-rated supply. Some cross-border supplies are zero-rated, meaning you charge 0% but can still reclaim your input tax. The treatment varies by what you sell and to whom, so confirm the position for your specific supplies with Revenue Jersey at gov.je or ask your bookkeeper.
What happens if I file my GST return late?
Late filing and late payment can attract penalties and interest, and persistent lateness draws closer scrutiny from Revenue Jersey. The amounts and rules can change, so check the current position on gov.je. The simplest protection is to keep your bookkeeping current so returns are quick to prepare and the cash is already set aside.
Can I reclaim GST on business expenses before I register?
There are limited circumstances in which pre-registration input tax can be recovered, but the rules are specific and evidence-dependent. You will need valid GST invoices and the expenses must relate to your taxable business activity. Because the detail matters, confirm your eligibility with Revenue Jersey or a bookkeeper before claiming anything.
