When we asked attendees at our recent webinar to describe the Autumn Budget 2025 in one word, 60% chose shambolic. The sentiment is understandable. With the Office for Budget Responsibility (OBR) releasing information before the Chancellor’s announcement, and a comprehensive range of changes affecting everyone from pensioners to business owners, this budget has created some uncertainty about financial futures.
However, amid the complexity, one message emerged clearly: we are living through what might aptly be termed the “taxation twenties”—and understanding how to navigate these changes could have a substantial impact on your wealth.
The highlights
- Income tax thresholds frozen until 2031 mean more people will be dragged into higher tax bands as salaries increase with inflation.
- Salary sacrifice changes from April 2029 will remove National Insurance relief on pension contributions above £2,000.
- Property and savings tax rates rise by 2% from April 2027, with rental income taxed at 42% for higher rate taxpayers.
- A high-value property surcharge will see an annual charge of £2,500-£7,500 on properties valued over £2 million from April 2028, with rates rising in line with inflation.
- Inheritance tax thresholds will be frozen until 2031, with pensions entering estates from April 2027, pushing nearly 10% of estates into IHT liability by the end of 2030.
- Core pension benefits have been preserved, including the £60,000 annual allowance, 25% tax-free lump sum, and 40-45% tax relief for higher rate taxpayers.
The economic reality check
The Bank of England base rate currently stands at approximately 4% and is likely to remain at this level for the foreseeable future. This indicates that mortgage rates will probably remain between 4% and 5% for the short to medium term—not the historically low rates experienced in recent years, but certainly in line with long-term averages.
The more pressing challenge lies in government finances. This year alone, the government will spend £111 billion solely on debt interest, which represents 8.3% of total public spending, or just over 3% of national income. To contextualise this, it’s equivalent to spending £1 of every £10 earned to service existing debt.
We face a forecasted 5.4% increase in taxation as a proportion of national output, from 2020 until the end of 2030. Combined with inflation, which is currently running at 3.7%, this creates a challenging environment for wealth accumulation and preservation.
The stealth tax affecting your income
The most significant revenue generator for the government looks to be the continued freeze on personal tax thresholds until 2031. The practical impact of this for individuals is substantial.
Consider this scenario: if the higher rate tax threshold had risen in line with inflation throughout this decade, it could stand at approximately £70,000 by 2030-31, rather than the frozen £50,270. This means a person earning £70,000 by the end of the decade may pay roughly £4,000 more in taxes annually than they would have, had the threshold not been frozen.
By 2030, it’s expected that 15% more people will be paying higher and additional rate tax, when compared to 2021-22. Whilst you may not miss the income never received, the cumulative impact on household finances remains considerable.
Pensions: Retaining significant benefits until 2029
Despite extensive pre-budget speculation regarding potential pension reforms, the fundamental advantages remain intact for now. The annual tax-free allowance remains at £60,000, the pension commencement lump sum (the 25% tax-free entitlement) continues unchanged, and higher rate tax relief stays at 40-45%.
However, the government has introduced a noteworthy change to salary sacrifice arrangements. From April 2029, pension contributions via salary sacrifice will have a tax-free limit of £2,000. Anything above this will be subject to national insurance contributions.
This creates a defined window of opportunity. Between now and April 2029, there is time to maximise salary sacrifice contributions before this change takes effect. For illustrative purposes only, for an individual with the full £60,000 tax-fee allowance, this represents potentially £180,000 in contributions with full National Insurance relief.
The property and investment environment
Property investors and landlords face an increasingly challenging landscape. From April 2027, tax rates on property and savings income will increase by 2% across all bands. Combined with the ongoing Renters Rights Bill, this could encourage more landlords either to divest or increase rental rates, ultimately affecting tenants more significantly than property owners.
Some investors use Real Estate Investment Trusts (REITs) as a way to gain exposure to property without owning assets directly. These can be held within tax-efficient wrappers such as ISAs and pensions, where growth and dividends remain tax-free. Whilst they do not escape the broader tax increases entirely, they do offer diversification and professional management without the administrative burden of direct property ownership.
The new high-value property surcharge arriving in April 2028 adds further complexity. Properties valued over £2 million will incur an annual charge ranging from £2,500 to £7,500, with rates increasing in line with inflation. This measure could particularly affect elderly homeowners, who may possess significant property wealth but receive modest retirement income.
Estate planning becomes increasingly important
With Inheritance Tax (IHT) thresholds frozen until 2031 and pensions entering estates from April 2027, nearly 10% of all estates will be subject to IHT by the end of 2030, representing a significant increase from just over 4% two years ago.
The implications are clear: proactive estate planning has become more important for those with substantial assets.
Practical steps to consider
The opportunities for action depend upon individual circumstances, but several principles apply broadly:
Maximise tax-efficient allowances
Utilise ISAs for yourself and your partner and consider junior ISAs for children. These remain valuable instruments even with the upcoming changes to cash ISA limits.
Review your income strategy
If you are a business owner or company director, consult with your accountant to optimise income extraction through an appropriate combination of salary, dividends, spousal allowances, and pension contributions.
Act on pensions before 2029
Whether employed or self-employed, there remains a limited window to maximise current salary sacrifice benefits. Prompt action is advisable.
Evaluate your property strategy
If you are a landlord, assess whether direct ownership continues to offer optimal tax efficiency or whether alternatives such as REITs are appropriate.
Initiate estate planning discussions.
With an increasing number of estates being drawn into the Inheritance Tax ‘net’, gifting strategies and comprehensive planning become even more important.
The broader context
We are at the beginning of this government’s term, facing challenging economic conditions with persistent interest rates, sustained inflation, and rising debt servicing costs. Pressures on welfare spending and NHS funding remain unabated. It is reasonable to anticipate that further tax increases may materialise.
Adopting a proactive rather than reactive approach positions you more favourably. Consulting with an Independent Financial Adviser to review your income sources, asset structure, and long-term strategy is more important than ever.
The taxation landscape has evolved considerably, and further changes appear likely. The pertinent question is not whether these developments will affect you, but rather how well prepared you will be when they do.

The value of your investments (and any income from them) can go down as well as up and you may not get back the full amount you invested.

Investments should be considered over the longer term (minimum of 5 years) and should fit in with your overall risk profile and financial circumstances.
A pension is a long-term investment not normally accessible until 55 (57 from April 2028). The fund value may fluctuate and can go down, which would have an impact on the level of pension benefits available. Past performance is not a reliable indicator of future performance.
The tax implications of pension withdrawals will be based on your individual circumstances. Thresholds, percentage rates, and tax legislation may change in subsequent Finance Acts.
