What is the Autumn Budget & Why It Matters
Each Autumn, the UK government issues its main fiscal statement: how it will raise revenue (taxes), how it will allocate spending to public services (health, education, infrastructure, etc.), and how it aims to meet its fiscal rules on borrowing and debt. It’s one of the most important political and economic events of the year.
Chancellor Rachel Reeves will deliver the Autumn Budget 2025 on 26 November.
Alongside her speech in the House of Commons (around 12:30 UK time, after Prime Minister’s Questions), the Treasury publishes detailed policy documents, and the Office for Budget Responsibility (OBR) delivers its independent forecasts on growth, borrowing, and public finances.
Pressures the Chancellor is Facing
Understanding what might be announced requires knowing what Reeves and her team are balancing:
- The fiscal gap: Higher borrowing costs, persistent inflation, and slower growth mean government revenues are under strain.
- Political pledges: The government has committed not to increase income tax, VAT, or national insurance, narrowing its options.
- Property focus: Because of the above pledges, speculation is strong that property taxation could become a main revenue source, with landlords, investors, and owners of high-value homes particularly in the spotlight.
What Could Be on the Table: Key Speculated Measures
| Measure | What is being considered | Potential Impacts |
| Annual Property Tax replacing or reforming Stamp Duty and Council Tax | Introduce an annual levy on homes above certain thresholds, possibly in place of or alongside Stamp Duty. | Homeowners in high-value regions (London, South East) could face new yearly costs. |
| Capital Gains Tax (CGT) on Primary Residences | Limit or remove the exemption for high-value homes (rumoured threshold £1.5m+). | Owners of expensive homes may face unexpected tax bills when selling. |
| National Insurance on Rental Income | Apply NI contributions to rental income, currently exempt. | Landlords would see higher tax bills; costs may be passed to tenants. |
| Inheritance Tax (IHT) Reforms | Adjust nil-rate bands, change gifting rules, or introduce new lifetime caps. | Families planning to transfer wealth could be affected, especially estates with property. |
| Property Wealth Tax / Council Tax Reform | Update outdated council tax bands or levy wealth-based property charges. | Owners of very high-value properties could see annual tax rises. |
| Threshold Freezes | Keep income tax thresholds frozen, creating “stealth taxes.” | More middle earners will gradually pay higher tax rates. |
What is Less Likely
- A full wealth tax on all assets — politically risky and administratively complex.
- Sudden, large increases to income tax or VAT rates — these are considered unlikely due to manifesto commitments and voter sensitivity.
Autumn Budget
What to Watch Closely
- Treasury documents and OBR forecasts: They’ll reveal the assumptions behind the budget.
- Details of property tax reforms: Thresholds, exemptions, and whether changes affect current homeowners or only new buyers.
- Impact on landlords and investors: National Insurance on rental income could reshape buy-to-let returns.
- Balancing act: The government must raise revenue without triggering backlash or harming growth.
The Autumn Budget on 26 November 2025 is shaping up to be pivotal, especially for property and wealth taxation. While headline tax rates are unlikely to move, landlords, homeowners, and investors should prepare for changes to property taxes, capital gains, and inheritance rules. Staying alert to these measures is essential for effective financial and investment planning.
