Given the heat this debate is currently getting (Press report on Chamber response to Social Security Reform as part of GST, Bailiwick Express on Suggested Income Tax rise backed by CGi), I thought I’d reflect on the topic. This is not a post about whether GST is good or bad, it’s a post about whether Guernsey is going to be honest with itself about what’s coming, why it’s coming, and what we need to get right.
If we’re not careful, we’re going to repeat mistakes that our neighbours made seventeen years ago.
The Fiscal Reality We Keep Avoiding
Guernsey has a structural deficit that, depending on how you measure it, is now approaching £100 million a year (according to the policy letter in November 2025). Let that land for a moment.
This isn’t a temporary dip. It’s not a post-pandemic blip. It’s a gap between what we spend on public services and welfare, and what we raise in tax, that has been building for years while successive States committees warned about it, published reports on it, and then kicked the can down the road. Despite the evident squeeze, the States have been spending more on the day to day and continue to vote through capital projects at great cost.
In 2024, 54% of total government revenues (including underlying entities revenue1 – 79% of headline revenue) were through personal income tax and social security (2024 States of Guernsey Accounts). That’s an extraordinarily narrow base for an island of our complexity. It means our finances are fragile. In practice it also means wealthy people with low declared income contribute less than those earning income from working. It means we can’t fund the hospital, schools, and infrastructure that people rightly expect without either raising income tax, which has its own consequences, or broadening how we collect revenue.
Let alone the impending democratic time bomb that the island will need to deal with.
A goods and services tax, at its core, is about broadening the base. That’s not a political slogan. It’s an economic reality.
What Jersey Did – and What Actually Happened
Jersey introduced GST in 2008 at 3%, having concluded there was a £40-45 million revenue shortfall that couldn’t be closed any other way. Sound familiar?
To be fair to Jersey, they tried to cushion it. They raised income tax allowances, increased Income Support payments, and introduced a Community Costs Bonus for lower-income households. They did the socially conscious version of the introduction, at least on paper.
But here’s what followed.
Within three years, despite an election campaign where the then Treasury minister gave what he described as a “categoric assurance” that he would not bring proposals to raise GST, the rate went up to 5% in 2011 because the structural deficit hadn’t gone away. Jersey then endured over a decade of economic stagnation. By 2015, an austerity package cut £10 million from support for the most financially vulnerable in the island — the very people GST had hit hardest in the first place.
A Jerseyman writing in the Guernsey Press put it plainly a few years ago2: if he had to sum up Jersey’s experience with GST in one word, it would be failure. Not because consumption taxes don’t work — they work all over the world — but because Jersey used GST to paper over a structural problem without addressing spending, and without being honest with the public about what was coming next.
The lesson isn’t “don’t do GST.” The lesson is: don’t introduce a tax, promise it will fix everything, promise the rate will never change, and then be surprised when it doesn’t fix everything and you need to raise the rate.
What’s on the Table for Guernsey
The proposal currently in front of the States is known as GST-plus – and it’s more complex than just a new tax on your shopping.
The full package includes:
A 5% GST on most goods and services – modelled closely on Jersey’s system. If food is zero-rated, the rate would need to be 6% to raise the same revenue.
Social security reforms – most people on low and middle incomes would pay less in contributions, because everyone gets a new allowance before contributions kick in. The rate on income above that allowance rises to compensate. However, the burden falls on local businesses (more on that to come another day).
A new 15% income tax band on roughly the first £32,400 of earnings – intended to reduce the tax burden on lower earners as part of the overall redistribution within the package.
Benefit and pension uprating — the States has committed to increasing pensions and benefits ahead of GST being applied, so recipients don’t face a 12-month wait to be compensated for higher prices. The estimated inflationary impact of GST on the island’s price level is around 3.2%. The RPI inflation rate currently sits at 3.4% for the UK3 – with the Iran conflict it is likely to be even higher, with an additional cost of GST to factor in for 2028 (expected introduction).
In addition, the social security package which shifts the burden to businesses to the tune of GBP 17 million, may well be inflationary in itself.
The net additional revenue target is £50 million a year. That’s roughly half of the structural deficit at current estimates, and the deficit is growing. For 2026, the budgeted deficit (before factoring in any investment returns is GBP 78 million)4.
The earliest GST could be introduced is early 2028, given the systems, legislation, and business preparation required.
In should be noted that much of the challenge about the above numbers is that the revenue service is so far behind, with inaccurate data, poor systems and an inability to even make repayments. The data behind these proposals has to be questionable, when the primary source of income is collected by a department which continues to be failing.
The Arguments For and Against
I work with businesses and individuals across this island every day, so I’ve heard both sides at length.
The case for GST is genuinely strong. Guernsey is almost unique among comparable jurisdictions in not having a consumption tax. Jersey has one. The Isle of Man has one. The UK, Ireland, New Zealand, Australia – every developed economy you can name has one. The argument that it would make Guernsey uncompetitive simply doesn’t stack up when our main competitors all have it too.
A consumption tax also captures what income tax can’t: the spending of people who are asset-wealthy but income-light. Anyone who has done tax planning work knows that high-net-worth individuals can legitimately structure their affairs to show very modest taxable income. GST doesn’t care about that. You spend money on this island, you contribute to its costs.
The case against is also real. GST is regressive by nature. A family spending a higher proportion of their income on essentials will feel a 5% levy more sharply than someone with money to spare. The proposed compensating measures help, but only if they’re well-designed and properly maintained over time. Jersey’s experience shows they can drift.
The food question matters enormously. Whether food is zero-rated isn’t a technical footnote – it’s the difference between a tax that hits lower-income households significantly harder and one that is at least somewhat fairer in practice. That decision is still to be made.
And then there’s the question of trust. Asking islanders to accept a new tax requires confidence that it will be managed responsibly, that the rate won’t creep, and that it genuinely forms part of a coherent long-term fiscal plan rather than a short-term fix. Given that the structural deficit is approaching £100 million and the proposed GST-plus package raises £50 million, that question needs to be answered honestly.
What I Think We Need to Get Right
As someone who spends my professional life helping Guernsey businesses and individuals navigate financial decisions, here’s what I think matters:
Design it properly. The exemption question – especially food – is not something to decide based on political convenience. Get it right from the start, because unpicking it later is much harder. Jersey was told it was too complicated to exempt food. Somehow it wasn’t too complicated to exempt yacht fuel. Complexity in law shouldn’t mean we fail to do the right thing. We’ve experienced a number of years of food inflation, with further inflation to come this year, there is a real argument for essentials to be protected from GST.
Be honest about the rate. If there is any reasonable scenario under which a 5% rate isn’t sufficient in five years’ time, say so now. Don’t make promises that can’t be kept. The erosion of public trust in Jersey after the 2011 rate rise did lasting damage.
Address the spending side too. £50 million of new revenue doesn’t close a reported £100 million gap. Any credible plan has to include a serious, accountable commitment to expenditure control alongside the tax reform. We’ve seen too many “savings targets” in States budgets that quietly evaporate. A civil service wage bill that was £318m in 2024 – up from £216m in 2014 (a rise of 45% compared to RPI during the same period of 38%) demonstrates growth beyond simple pay rises.
Don’t delay indefinitely. The July 2026 debate is already being talked about as a candidate for postponement. Credit to Deputy De Sausmarez indicating it won’t be delayed. (But the reality is the (now former) political lead is embroiled in very public personal issues).
Every year of delay costs real money and defers decisions that are only going to get harder. Guernsey has been debating this for the better part of a decade. At some point, not deciding is itself a decision, and not a good one.
The Bottom Line
Guernsey needs to raise more revenue. The numbers are clear, the structural deficit is real, and the reserves we’ve been drawing on to paper over the gap won’t last forever. Equally there needs to be real savings made by our States. People see waste, and that makes selling the concept of GST challenging.
The question in front of us isn’t really whether something needs to change. It’s what that change looks like, and whether we have the political maturity to design it well and be honest about it.
Jersey experienced what happens when you introduce a new tax to solve a structural problem and pretend you’ve fixed something you haven’t. Both islands’ finances are being propped up by financial asset gains which can very quickly evaporate. I’d rather we looked that reality in the eye now than spend the next decade discovering it the hard way.
