Budgets have a habit of turning into a national guessing game. In the weeks beforehand, almost every tax, allowance and government spending programme seems to find its way into the rumour mill.
This one arrives against a particularly complicated backdrop. Chancellor John Healey will deliver his first Budget on 28 October, alongside a new economic and fiscal forecast from the Office for Budget Responsibility. He has promised fiscal discipline, while the Government is also facing pressure from higher borrowing costs, energy prices and demands for additional spending (see the Government’s Budget announcement here).
Rather than trying to predict the contents of the red box, here are ten things worth keeping an eye on when the Chancellor stands up at the despatch box.
1. Income Tax: Watch the Thresholds, Not Just the Rates
The Government has continued to rule out increases to the main rates of Income Tax, National Insurance and VAT. But the rate itself is only part of the story.
The Personal Allowance is currently £12,570 and the higher-rate threshold £50,270, with legislation already in place to keep those thresholds frozen until April 2031. As wages rise, more income can therefore become taxable even if the headline tax rates do not change, something often referred to as fiscal drag.
So one box on our Budget Bingo card is simple: does the Chancellor leave those thresholds untouched?
2. Capital Gains Tax
Capital Gains Tax has already generated plenty of speculation. Reports had suggested the Government could consider bringing CGT rates closer to Income Tax rates, but Healey has now ruled out full equalisation.
That does not necessarily mean CGT is off the table altogether. A more modest change could still be considered, and the Treasury is also reportedly looking at possible reliefs designed to encourage people to reinvest gains into UK businesses (Reuters).
For investors and business owners, this will be one of the areas worth listening to particularly closely.
3. Inheritance Tax and Pensions
There is already a major change approaching in this area. From 6 April 2027, most unused pension funds and pension death benefits will be included within an estate for Inheritance Tax purposes.
That change has now been legislated for, so the important question is whether the Budget brings any further adjustments to the rules around pensions, estates or Inheritance Tax planning as implementation gets closer.
Even if nothing new is announced, the approaching 2027 deadline means this is an area many families may need to revisit.
4. ISAs
Another change already in the pipeline concerns Cash ISAs. From April 2027, the annual Cash ISA subscription limit for people under 65 is due to fall to £12,000, while the overall ISA allowance remains £20,000. Those aged 65 and over will retain a £20,000 Cash ISA limit.
With the Government keen to encourage more people to invest rather than hold long-term savings entirely in cash, it will be interesting to see whether the Budget confirms the direction of travel or adds anything further to the ISA landscape.
5. Property Taxes
Property is another area that has attracted plenty of attention. A new annual charge on homes worth more than £2 million is already due to come into effect from April 2028.
There had been speculation that the £2 million threshold could be reduced to £1.5 million, but this is reported to be ruled out. The Budget could nevertheless provide further details on how the levy will operate, valuations and whether property taxation forms part of any wider reforms.
For homeowners, the detail may prove just as important as the headline.
6. Energy Bills
This is likely to be one of the most immediately noticeable areas for households.
The Government removed VAT from domestic electricity bills from 1 October, a move it estimates will reduce the annual Ofgem price cap by around £45. But the measure has so far been funded on a temporary basis, while energy costs remain under pressure.
There is therefore considerable interest in whether the Budget provides more targeted support, extends existing help or sets out a longer-term plan for household energy costs. Reports have suggested further support for lower-income households is among the options being considered.
7. Fuel Duty and the Cost of Driving
It may not grab the same headlines as Income Tax or pensions, but fuel duty affects millions of households and businesses directly.
The temporary fuel-duty reduction currently in place is scheduled to end in January, meaning the Chancellor must decide whether to allow it to expire or extend the support. With fuel prices and wider energy costs under pressure, this is another relatively small Budget decision that could have a noticeable impact on everyday spending.
One for anyone who watches the numbers on the petrol pump almost as closely as the Chancellor watches the OBR.
8. Businesses, Business Rates and Sector Taxes
Businesses will also be looking for clues about the Government’s approach to growth. Burnham’s administration has already signalled changes to business rates and greater powers for local and regional authorities, while speculation has also included the possibility of further taxes on particular sectors, including banks.
For business owners, the important details may not be a single headline tax change. Changes to rates, investment incentives, local taxation or sector-specific measures could all affect the cost of running and investing in a business.
9. Where the Government Chooses to Spend
Budgets are not only about tax.
Higher defence spending, public services, welfare, social care and cost-of-living support are all competing for limited room within the public finances. The Institute for Fiscal Studies has warned that the Chancellor faces around £35 billion of spending pressures in the years ahead if existing public service ambitions are to be delivered.
Where Healey chooses to spend, cut or delay spending could therefore be every bit as significant as the individual tax announcements.
10. The Numbers Behind the Budget
Finally, perhaps the most important part of the day may be the bit that receives less attention than the Chancellor’s headline announcements.
The Office for Budget Responsibility will publish a new economic and fiscal forecast alongside the Budget, covering areas including economic growth, inflation, borrowing and government debt.
Those forecasts help determine how much room the Government believes it has to spend or cut taxes. They can also influence financial markets because investors will be looking closely at whether the Government’s plans for borrowing and spending appear credible.
The IFS argues that the debate about the Chancellor’s fiscal “headroom” can sometimes obscure the bigger question: whether the Government has a credible long-term plan for spending and borrowing (IFS).
Eyes Down
There will inevitably be more rumours between now and 28 October, and some of the things attracting the biggest headlines today may never make it into the final speech.
That is why it is worth separating what has already been announced, what is genuinely under consideration and what is simply speculation.
For households, investors and business owners, the important question after the Budget will not just be which boxes we managed to tick on our Budget Bingo card. It will be what the collection of changes means when viewed together, and whether anything needs to change in your own financial plans.
