The Autumn Budget 2025 landed on 26th November, and while the build-up had plenty of speculation, the reality is simpler… Taxes are rising in some areas, allowances are changing, and there are targeted benefits for certain businesses and households. This guide breaks down everything you need to know in plain English, perfect for individuals, savers, property owners, and SMEs looking to plan their finances.
Tax & Personal Finance Key Changes
Frozen Income Tax Thresholds
The government has extended the freeze on income tax thresholds until 2031. This means that even if your salary increases in line with inflation, you may gradually be pushed into higher tax brackets. This is a classic example of a “stealth tax” that affects millions of taxpayers over time.
Higher Taxes on Dividends, Savings, and Property
From April 2026, Tax rates on dividends will increase by 2 percentage points and then from April 2027 the rates for rental income, and savings interest will also increase by 2 percentage points. For investors and landlords, this is an important consideration when planning income strategies or evaluating investment returns.
Reduced Cash ISA Allowance
For savers under 65, the Cash ISA allowance is cut from £20,000 to £12,000 per year from April 2027. This reduces the tax-free shelter for cash savings, making it important to explore alternative options like Stocks & Shares ISAs or pension contributions.
Pension Contributions & Salary Sacrifice
From April 2029, salary sacrifice pension contributions above £2,000 will now be subject to NIC. Individuals using this strategy should review their contributions to ensure it remains tax-efficient.
Fuel Duty Freeze & EV Changes
Fuel duty is frozen until September 2026, offering short-term relief for motorists. However, from 2028, electric vehicles (EVs) and plug-in hybrids will face a mileage-based charge, impacting long-term EV ownership costs.
New Mansion Tax
From April 2028, high-value homeowners will face a new surcharge on properties valued over £2 million, which could affect estate planning and property investment strategies.
Business & Investment: What SMEs and Companies Need to Know
Corporation Tax & Capital Allowances
Corporation tax remains unchanged, but writing-down allowances for assets will fall from April 2026 from 18% to 14%. In contrast, a new 40% First Year Allowance is introduced on assets bought on or after 1st January 2026, allowing businesses to deduct 40% of qualifying capital expenditure in the first year on main rate assets. This is a significant incentive for businesses investing in machinery or equipment.
Reduced Business Rates for High-Street Sectors
Retail, hospitality, and leisure businesses will benefit from lower business rates from April 2026, helping SMEs maintain cash flow and competitiveness in challenging markets.
Apprenticeship Training for Under-25s
SMEs can now access fully funded apprenticeship training for under-25s, removing the co-investment burden, starting from April 2026. This is an excellent opportunity for businesses to invest in young talent at no extra cost.
Household Impacts: Cost of Living & Savings (From April 2026)
- Eco-Energy Scheme Ending – Households can expect lower energy bills from April next year.
- National Minimum Wage Rise – Employees will see higher minimum wages, affecting payroll and household income.
- Removal of Two-Child Benefit Cap – Families with more than two children will receive full child benefit again.
- Sugar Tax Introduction – Beverages high in sugar will face new taxation, encouraging healthier consumption and impacting household spending.
What This Means for Individuals, Families & Businesses
For Individuals & Savers:
- Review savings and investment strategies – Cash ISAs now have a lower cap, and dividend/savings income is taxed higher. Consider alternatives to shelter income from tax.
- Reassess pension contributions – With salary-sacrifice changes, the first £2,000 remains tax-efficient, review contributions above this level.
- Plan for “stealth tax” effects – Frozen thresholds could gradually push you into higher income tax bands over time.
For Businesses & SMEs:
- Maximise capital allowances – Take advantage of the 40% First Year Allowance for qualifying asset investments.
- Consider apprenticeships – Fully funded training for under-25s can reduce costs and attract young talent.
- Check eligibility for business rate reductions – Retail, hospitality, and leisure businesses may save significantly.
For Property & Investment Income Earners:
- High-value homeowners – Plan for the new mansion tax on properties over £2 million.
- Landlords and investors – Higher taxes on rental income and savings returns may require reassessment of property portfolios or investment strategies.
Budget Planning is Essential
The Autumn Budget 2025 signals that traditional “set and forget” financial strategies may no longer work. Key takeaways:
- Savers and investors should reconsider tax-efficient strategies.
- Business owners have new opportunities in investment and apprenticeships but must act strategically.
- Households will see some relief through lower energy costs, but tax increases on dividends, property, and savings could offset benefits.
