Autumn Budget 2025 Key Changes — What They Mean for You
The Chancellor’s Autumn Budget 2025 introduces major tax and policy reforms that will impact individuals, families, landlords, and businesses across the UK. At Marsal Accountants, we break down the key announcements and explain how they may influence your financial planning over the coming years.
Tax and Savings
- Income Tax and National Insurance thresholds frozen until 2031 — more people may drift into higher tax brackets due to fiscal drag.
- Cash ISA allowance reduced from April 2027: under-65s limited to £12,000 tax-free; savers 65+ retain £20,000.
- New pension salary-sacrifice cap from April 2029. NI relief capped at £2,000 per month, reducing the tax efficiency of larger contributions for higher earners.
Property and Lifestyle
- Council tax surcharge for high-value properties — homes over £2m face annual “mansion tax” of £2,500–£7,500 starting 2028.
- Electric vehicle (EV) mileage tax introduced to replace lost fuel duty revenue, affecting private and business EV users.
Business and Employer Impacts
- National Living Wage increase to £12.71/hr for workers aged 21+ from April 2026.
- Higher employment costs due to salary expectations, payroll obligations, and pension NI changes.
- Sector-specific tax rises, e.g., gambling industry: remote gaming duty 40%, online betting tax 25%.
