After months of speculation and rumour, chancellor Rachel Reeves has delivered the Autumn Budget for 2025. In this update, we’ll explain the key changes and what they mean for you.
Last year, in her maiden Budget, the chancellor sought to balance the public finances with tax rises to cover a reported £22 billion black hole.
This year, Reeves arguably faced an even more difficult landscape. In turn, she has announced an estimated £26 billion of tax rises by 2029/30.
The chancellor had to start her speech, however, by acknowledging the “deeply disappointing” and “serious error” of the Budget announcements being released early by the Office for Budget Responsibility (OBR).
It’s also notable how many predictions ultimately proved to be wide of the mark.
Now that we know exactly what’s included, it’s important to understand the changes and how they could affect you.
The headlines regarding GDP, national debt, and inflation
The chancellor says the government’s plans will reduce borrowing more over the rest of this parliament than any country in the G7.
GDP is expected to grow by 1.5% in 2025, higher than the OBR’s 1% forecast from earlier this year. In subsequent years, the estimations are as follows:
- In 2026, the economy is forecast to grow by 1.4%,
below the previous forecast of 1.9%. - In 2027, GDP is forecast to expand by 1.6%,
falling short of March’s estimate of 1.8%. - In 2028, GDP is estimated to rise by 1.5%.
In March of this year, the OBR said this figure would be 1.7%. - In 2029, the economy will expand by 1.5%,
again falling short of the previous estimate of 1.8%.
Due to weaker underlying productivity growth, the OBR estimates that tax receipts will be £16 billion lower in 2029/30 than initially forecast in March 2025.
Average inflation is expected to fall over the next three years.
- In 2025: 3.5%, an increase of 0.2% from the OBR’s original forecast.
- In 2026: 2.5%, up from the OBR’s 2.1% forecast from March.
- In 2027: 2%.
National debt will stand at £2.6 trillion this year. £1 in every £10 the government spends is on debt interest.
Tax threshold freezes extended until 2031
The Labour manifesto promised not to increase Income Tax or National Insurance (NI), and despite pre-Budget speculation, the government has kept to that promise in this Budget.
However, the chancellor did announce that the Income Tax thresholds will remain frozen for a further three years beyond the previous 2028 freeze, staying where they are until April 2031. This move will raise £8 billion for the government. Similarly, the Inheritance Tax (IHT) threshold freeze is extended from 2030 to 2031.
While this will not increase your Income Tax or IHT bills directly, this fiscal drag means more of your income and wealth may be exposed to tax over time.
The government is also upholding its commitment to bringing pension pots into the scope of IHT from April 2027, and reforms to relief for business and agricultural assets from April 2026.
The tax rates on dividends, savings, and property income will rise by two percentage points
Tax rates are set to rise for dividends, savings, and property income.
Dividends:
From April 2026, ordinary and upper rates of tax on dividend income will rise by two percentage points to 10.75% and 35.75% respectively. There is no change to the additional rate, which will remain at 39.35%.
Property and savings:
From April 2027, the rate of tax on property and savings income will increase by two percentage points across all tax bands to 22%, 42%, and 47% respectively.
The government confirmed that, even after these reforms, 90% of taxpayers will still pay no tax on their savings. However, these changes are set to impact business owners and landlords.
The chancellor says these increases will raise £2.2 billion in 2029/30.
The ISA allowance will be reformed for under-65s, and some allowances have been frozen
The chancellor announced that from April 2027, the Individual Savings Account (ISA) allowance will change for under-65s.
As it stands, adults can contribute £20,000 across their ISAs, including Cash ISAs and Stocks and Shares ISAs, each tax year.
From April 2027, £8,000 of this allowance will be reserved exclusively for investments, leaving an available £12,000 that savers can pay into their non-investment accounts, such as Cash ISAs.
Savers over the age of 65 will continue to be able to save up to £20,000 in a Cash ISA each year.
The allowances for Junior ISAs and Lifetime ISAs are frozen until April 2031 at £9,000 and £4,000 a year, respectively.
Salary sacrifice on pension contributions to be capped at £2,000
The chancellor put a cap on NI-efficient pension contributions made under salary sacrifice.
Salary sacrifice schemes cost the government £2.8 billion in 2016/17, but this figure was set to triple to £8 billion by 2030/31.
The government will charge employer and employee National Insurance contributions (NICs) on pension contributions above £2,000 a year made via salary sacrifice. This will take effect from 6 April 2029.
The chancellor says that many of those on low and middle incomes will be able to continue using salary sacrifice as normal, while high earners can expect to pay increased NI.
New “mansion tax” on high-value properties
The chancellor announced the much-speculated “mansion tax” that will affect the top 1% of properties.
The new property surcharge will be paid alongside Council Tax.
There will be four price bands starting with £2,500 for a property valued between £2 million and £2.5 million. For properties valued more than £5 million, the levy will be £7,500.
The measure is estimated to raise £400 million by 2031.
Welfare reforms expected to increase by 2029/30
The BBC reported that changes to the government’s previously announced winter fuel payments and health-related benefits will cost £7 billion in 2029/30.
In addition, Reeves revealed she would remove the two-child benefit cap. This will cost £3 billion by 2029/30.
State Pension: Removal of overseas access to Class 2 National Insurance contributions and committing to the triple lock
As a result of a loophole in the Class 2 voluntary NICs regime, overseas individuals with a limited connection to the UK can build a State Pension entitlement through cheaper rates.
The government is looking to end this by removing access to the cheapest Class 2 NICs for these individuals. Additionally, it will increase the initial residency or contribution requirements for those living outside the UK.
The chancellor also confirmed the government’s commitment to the triple lock. From April 2026, this will increase the basic and new State Pension by 4.8%, offering up to an additional £575 per year to pensioners, depending on their entitlement.
A range of significant changes for business owners
In addition to the Dividend Tax increase, the chancellor announced a range of changes that could affect business owners, including:
- Increases to both the National Living Wage (NLW) and National Minimum Wage (NMW). From 1 April 2026, the NLW paid to workers aged 21 and over will rise by 4.1%, from £12.21 to £12.71 an hour, increasing annual income by approximately £900 a year for full-time employees. For those aged 18 to 20, the NMW will rise by 8.5% from £10 to £10.85 an hour, equivalent to around £1,500 a year if working full-time. For 16- and 17-year-olds, and those on apprenticeships, the NMW will rise by 6%, going from £7.55 to £8 an hour.
- Listing Relief from Stamp Duty Reserve Tax for some businesses. The chancellor said this will “make it easier for entrepreneurs to start, scale, and stay in the UK”.
- Reduced Capital Gains Tax (CGT) relief for Employee Ownership Trusts (EOTs). When a business is sold to an EOT, CGT relief will fall from 100% to 50% starting from November 2025. This will raise £0.9 billion from 2027/28 onwards.
- Fully funded apprenticeships for under-25s. This will make them effectively free for small- and medium-sized businesses (SMEs) from April 2026.
- Lower business rates for more than 750,000 retail, hospitality, and leisure properties. That move will be funded through higher rates on properties worth £500,000 or more, such as warehouses used by online retail.
- Customs duty will apply to parcels of any value from March 2029 at the latest. There is an existing exemption for parcels worth less than £135, favouring large-scale importers.
Other announcements that may affect you
- Household energy bills will fall. Reeves is scrapping the Energy Company Obligation (ECO) scheme, saying that on average, families will save £150 a year in 2026.
- A new tax on electric vehicles. The Electric Vehicle Excise Duty (eVED) will come into effect in 2028 and equal 3p per mile for battery electric cars and 1.5p per mile for plug-in hybrids. The rate per mile will increase annually in line with the CPI.
- Fuel duty will be frozen until September 2026. In addition, a new “fuel finder” will help drivers find the cheapest fuel, saving the average household £40 a year.
- Reducing the levy threshold on soft drinks. From 1 January 2028, the sugar tax will also be applied to milk-based drinks, including bottled milkshakes and lattes.
- A spousal exemption for agricultural and business asset IHT relief. Unused combined business and agricultural asset IHT relief will become transferable between spouses and civil partners.
- Tobacco Duty and Alcohol Duty will both be uprated. Tobacco Duty will be uprated as announced last year, and Alcohol Duty will now rise with inflation.
- Rising taxes on online gambling. From April 2026, Remote Gaming Duty will increase by 21% to 40%. A new Remote Betting Rate set at 25% will be introduced from April 2027, though horse race betting will be exempt from the changes.
Other key thresholds that remain the same
More broadly, the chancellor made no mention of other key thresholds that will remain the same. These include:
- The pension Annual Allowance
- Stamp Duty Land Tax for residential properties
- The headline rates of Income Tax, NI, and VAT, as outlined in the government’s election manifesto.
