The Autumn Budget 2025 changes are still being analysed one week on, with businesses and individuals now starting to understand the long-term impact.
While there were no major headline tax rate increases, the Autumn Budget 2025 changes introduce structural shifts that will affect payroll, pensions, investments, and financial planning over the coming years.
In this guide, we break down the key updates and what they mean in practical terms.
Autumn Budget 2025 Changes: Freezing Tax Thresholds Explained
One of the most significant Autumn Budget 2025 changes is the extension of frozen tax thresholds.
The government confirmed that the following thresholds will remain unchanged between April 2028 and April 2031:
- Personal Allowance: £12,570
- Higher Rate Threshold: £50,270
- Additional Rate Threshold: £125,140
This policy strengthens tax revenue through fiscal drag.
What is fiscal drag?
As wages increase, more people move into higher tax brackets without any change in tax rates.
What this means
- Pay rises may not significantly increase take-home pay
- More employees will move into higher tax bands
- Employers must carefully assess net pay outcomes
Autumn Budget 2025 Changes to Dividend and Investment Tax
Another key part of the Autumn Budget 2025 changes is the increase in tax on non-wage income.
From 6 April 2026:
- Dividend basic rate increases from 8.75% to 10.75%
- Dividend higher rate increases from 33.75% to 35.75%
From 6 April 2027:
- Savings income tax rates increase by 2 percentage points
The aim is to reduce the gap between income from employment and income from assets.
What this means
- Lower net returns on dividends and investments
- Reduced efficiency of dividend-based remuneration
- Higher tax on rental and savings income
Autumn Budget 2025 Changes to Pension Salary Sacrifice
The Autumn Budget 2025 changes also introduce a major update to pension salary sacrifice.
From 6 April 2029:
- Only the first £2,000 per year will remain exempt from NICs
- Contributions above £2,000 will incur employer and employee NICs
Standard employer pension contributions remain unaffected.
What this means
- Reduced tax efficiency of salary sacrifice schemes
- Potential increase in employment costs
- Need to review pension strategies early
Autumn Budget 2025 Changes: High Value Property Tax
The Autumn Budget 2025 changes introduce a new High Value Council Tax Surcharge.
From April 2028, properties worth over £2 million will be subject to additional charges:
- £2m – £2.5m: £2,500 per year
- £2.5m – £5m: Increasing bands
- £5m+: Up to £7,500 per year
What this means
- Increased costs for high-value property owners
- Potential impact on financial planning and relocation decisions
