3rd September 2026
There is a point at which a financial warning stops being something for accountants and politicians and becomes a warning for every taxpayer.
I think Scotland has reached that point.
On 24 August, Scotland's Auditor General Stephen Boyle published a remarkably direct blog about the future of Scotland's public finances. The language was unusually blunt.
The Scottish Government, he says, wants to spend almost £5 billion more on public services by 2030 than the funding currently available.
And that figure is not even based on all of the commitments made during the 2026 election campaign.
Around £2 billion of the gap is expected to come from rising social security spending, while the size and cost of Scotland's public-sector workforce has also grown significantly.
The Auditor General's warning is not that Scotland cannot afford public services.
It is that the current model cannot simply continue without major change.
That distinction is crucial.
Someone eventually pays
There are only a limited number of ways for governments to close a persistent gap between what they want to spend and the money available.
They can raise more tax.
They can borrow.
They can reduce spending.
They can change the way services are delivered so that they cost less.
Or they can use a mixture of all four.
There is no magic fifth option.
And that means the £5 billion gap is not really a problem belonging to Holyrood.
Ultimately, it belongs to taxpayers and to the people who depend upon public services.
If taxes rise, taxpayers pay.
If services are reduced, citizens pay in a different way.
If borrowing increases, future taxpayers pay.
If services are reformed and become more efficient, there may be a way of reducing the bill without simply transferring the problem elsewhere.
The difficulty is that Scotland has been talking about reform for years.
The Auditor General's criticism is particularly uncomfortable
Stephen Boyle makes a point which should concern ministers across the political spectrum.
He says the Scottish Government has become good at producing strategies, frameworks and plans, but has struggled to deliver its policy ambitions.
Public service reform has been discussed for a long time, but Boyle says there has been little evidence of large-scale change on the ground since the creation of Police Scotland in 2013.
Instead, Scotland has often relied on short-term measures to balance individual annual budgets.
That may get a government through one financial year.
It does not solve a structural problem.
As Boyle puts it, the hardest decisions about the shape, size and operation of the public sector have not yet been taken.
That is probably the most important sentence in his blog.
What does "the size of the public sector" actually mean?
This is where the argument becomes politically difficult.
When politicians talk about protecting public services, most people instinctively agree.
Who wants fewer doctors, nurses, teachers, carers, police officers or other public servants?
But the question is not necessarily whether these people are needed.
It is whether Scotland can continue providing services in the same way, with the same structures, staffing arrangements and costs.
The public sector workforce has grown significantly since devolution and, according to Boyle, is relatively larger than the UK public-sector workforce.
That creates what he describes as a lock-in of future spending.
Once thousands of additional employees are part of the system, their salaries, pensions and other employment costs become recurring commitments.
The same applies to buildings, contracts, IT systems and other infrastructure.
Government spending has a habit of becoming permanent.
Temporary spending is much easier to introduce than to remove.
The NHS is at the centre of the problem
The NHS illustrates the difficulty particularly well.
Scotland needs healthcare.
But simply putting more money into hospitals does not necessarily solve the underlying problem.
Boyle points towards prevention and community care as an example.
The basic idea is straightforward: help people earlier so that fewer eventually require expensive hospital treatment.
That should reduce pressure on hospitals and potentially save money.
Yet he points out that although structures have changed over the past decade, progress has been slow and the money has not followed the ambition.
Meanwhile pressure on hospitals continues to increase.
This is exactly the sort of problem that cannot be solved by another year's budget allocation.
The system itself has to change.
And this is where taxpayers should start paying attention
The debate over Scottish taxation often concentrates on whether the higher or additional tax rates are fair.
That is a legitimate debate.
But there is another question which receives much less attention:
How much additional revenue can Scotland realistically raise from taxation without damaging the tax base itself?
Audit Scotland has already highlighted an uncomfortable answer.
In 2025/26, the Scottish Government expected its income tax rates and bands to raise up to £1.7 billion more than if the UK income tax structure had been used.
But the Scottish budget was projected to benefit by only £616 million.
One reason is that Scotland's earnings and employment performance relative to the rest of the UK affects the operation of the fiscal framework.
In other words, raising more money from taxpayers does not automatically translate pound-for-pound into additional money available to the Scottish Government.
There is another potential problem.
If higher earners, businesses or skilled workers change their behaviour because of the tax difference, the expected additional revenue can be reduced.
This does not mean Scotland cannot raise taxes.
It means there are limits.
Higher taxes cannot be the whole answer
It would be perfectly possible to close part of the funding gap by increasing taxes.
But every increase has consequences.
Someone paying another £1,000 in income tax has £1,000 less to spend.
Some of that money might otherwise have gone into a local shop.
A restaurant, A tradesperson, A builder, A holiday, Savings or investment in a business.
There is therefore a difference between collecting more tax and creating more economic wealth.
The Scottish Government needs both.
A growing economy creates more taxpayers, higher wages and more business activity.
That expands the tax base without necessarily increasing tax rates.
A stagnant economy leaves government increasingly dependent on squeezing more money from the existing tax base.
That is not a sustainable long-term strategy.
Borrowing is another way of moving the problem
The same applies to borrowing.
Borrowing can be entirely sensible when it pays for infrastructure which provides benefits for decades.
A new school, housing development, transport infrastructure or energy project may justify long-term financing.
But borrowing is not free.
Interest has to be paid.
Capital eventually has to be repaid.
And the cost comes from future budgets.
That means today's borrowing can reduce tomorrow's ability to spend on services.
This is particularly important when governments are trying to maintain capital investment while simultaneously dealing with pressure on day-to-day spending.
It is easy to announce a new capital project.
It is much harder to explain what it will cost to finance, maintain and operate for the next 25 or 30 years.
Scotland has already been using short-term fixes
This is not the first time Audit Scotland has raised the issue.
Its 2024/25 audit of the Scottish Government found a £1 billion underspend, but warned that this had been supported by more than £2 billion of additional UK Government funding and one-off measures.
Audit Scotland said many of the savings identified were non-recurring and that this short-term approach was not supporting long-term financial sustainability.
Its assessment put the projected combined resource and capital funding gap at £4.7 billion by 2029/30.
That is remarkably close to the £5 billion figure Boyle is now discussing.
The message is therefore becoming harder to ignore.
This is not a sudden problem.
It has been building.
And now there is another word: reform
"Reform" sounds harmless.
It can mean better IT systems.
It can mean joining organisations together.
It can mean moving services online.
It can mean changing management structures.
But genuine reform can also mean closing something, merging something, changing staffing arrangements or ending a service which people have become accustomed to receiving.
That is why reform is politically difficult.
Boyle is effectively saying that Scotland has reached the stage where difficult decisions cannot be avoided simply by producing another strategy.
He wants detailed plans showing the steps required, the resources involved, the timescale and how success will be measured.
That sounds like basic financial management.
Yet it is precisely what has been missing.
What happens if nothing changes?
This is the question politicians need to answer.
Suppose Scotland continues broadly as it is.
Public-sector pay rises.
The population ages.
Demand for health and social care increases.
Social security spending rises.
The NHS requires more money.
Councils require more money.
Capital investment continues.
Debt costs increase.
And the economy does not grow sufficiently quickly to expand the tax base.
The gap gets bigger.
At some point there is no longer enough flexibility to solve it with small annual savings.
Then the choices become much more painful.
Tax increases become larger.
Services face deeper reductions.
Capital programmes are delayed.
Staff numbers come under pressure.
Or borrowing increases further.
None of those choices is attractive.
There is a warning here for Highland too
Although Boyle's blog is about Scotland's public finances rather than Highland Council, the same principle applies locally.
Highland is facing its own financial pressures while simultaneously wanting to maintain and expand capital investment.
That is perfectly understandable.
Highland has an infrastructure deficit and cannot simply stop investing.
But every council needs to distinguish between investing for the future and creating future financial obligations which become difficult to service.
The Glasgow financial warning published by Audit Scotland this week reinforces the point.
A council can balance an annual budget and still have serious longer-term financial problems.
The same principle applies to Holyrood.
A balanced annual Scottish Budget does not necessarily mean Scotland's public finances are sustainable.
The real question is what happens five or ten years from now.
The bill cannot be avoided forever
There is perhaps a temptation in politics to believe that another year of economic growth will solve the problem.
Or that another efficiency programme will produce the necessary savings.
Or that another tax increase will provide the missing money.
Perhaps each can contribute.
But none is likely to solve a £5 billion structural problem on its own.
That is why Stephen Boyle's intervention matters.
He is not a politician arguing for a particular tax rate or a particular level of public spending.
He is the Auditor General warning that the arithmetic is becoming increasingly difficult.
And his warning is unusually clear.
Scotland needs to move from announcing reform to actually delivering it.
What should taxpayers be asking?
The next Scottish Budget will inevitably be examined through the familiar arguments over tax rates and spending.
But taxpayers should perhaps ask some different questions.
And perhaps some questions fo candidates in the coming bi-eletion for Wick and East Caithness.
How much is the public sector going to cost in five years?
How many people will it employ?
How much will be spent on pensions?
How much will be spent servicing borrowing?
How much of today's savings are permanent?
How much relies on one-off money?
Which services are actually going to change?
How much will the reforms save?
And when will those savings actually appear?
Most importantly:
What happens if the savings do not materialise?
Those are not questions which belong only to accountants.
They are questions for every taxpayer.
Scotland has a choice, but the choices are narrowing
There is still time to change direction.
Audit Scotland's own view is that reform is possible.
But Boyle is also warning that the longer meaningful reform is delayed, the harder and more painful it will become. If the foundations are not put in place during this Parliament, the consequences for public services could be much greater in the future.
That is the real warning.
Scotland does not necessarily face a sudden financial crash.
The danger is something slower.
A gradual squeeze in which taxes rise, services become harder to access, investment is constrained and more and more of the budget is consumed by commitments made years earlier.
That would be a much less dramatic crisis than a government running out of money.
But for taxpayers and the people relying on public services, it could ultimately be more damaging.
The bill is coming.
The question is whether Scotland chooses to deal with it now, while there are still choices available, or waits until the choices become much more painful.
