As a trusted accountancy and advisory practice supporting clients in Cardiff, London, and across the UK, Carston ETL is committed to helping you navigate the complex financial landscape shaped by the 2025 Autumn Budget.
With deep expertise across tax, audit, corporate finance, and business advisory services, we understand how crucial it is to stay informed and prepared, particularly in a year where the Government has introduced one of the most extensive sets of fiscal changes in recent times.
This year’s Budget brings about major shifts that will undoubtably affect individuals, families, landlords, and businesses. Key announcements include:
- The freeze on income tax thresholds until 2031
- Higher taxes on dividends, savings and property income
- Expanded business rates relief for SMEs
- Changes to capital allowances
- New investment incentives for innovative and fast-growing companies.
Households will also feel the impact through the removal of the two-child benefit cap, strengthened disability support, and freezes on rail fares and NHS prescription charges.
We’ve distilled the most important measures into a clear, accessible summary to help you understand how these changes may affect your finances, whether you’re managing payroll, planning long-term investments, or reassessing your personal tax strategy.
