In 2025, the UK may witness one of the largest changes to property taxation in decades. The government is considering proposals to replace Stamp Duty Land Tax (SDLT) and potentially overhaul Council Tax, introducing a proportional property levy with a baseline payment of around £810 per household. The reforms aim to modernise taxation, reflect current property values, and make contributions fairer for all homeowners.

Why the Government Is Considering Reform
SDLT relies on housing market activity, creating uneven revenue streams, while Council Tax is based on property values from 1991, leaving the system outdated. The government wants to generate steady funding for local services without raising income tax, VAT, or National Insurance. Consultations for the Finance Bill 2025–26 and proposals from think tanks have provided frameworks for the ongoing debate.
Understanding the £810 Base Charge
Media reports have highlighted the £810 figure as a flat tax, but it is best understood as a baseline contribution under some reform models. This floor charge ensures that every property contributes to local council funding, with higher-value homes paying additional proportional levies. It is not a confirmed universal tax but a reference point in proposed models.
Proposed Changes in Detail
The property tax reforms under discussion include multiple layers:
| Proposal | Details |
|---|---|
| Abolition of SDLT | Buyers may no longer pay upfront stamp duty; a proportional annual property tax may replace it or be deferred until sale |
| National Property Levy | Properties above £500,000 face 0.54% annually; above £1 million, 0.81% on the higher band |
| Local Proportional Tax | Council Tax replaced with a local rate, e.g., 0.44% of property value |
| Minimum £810 Floor Payment | All households contribute a baseline amount to fund local services |
| Capital Gains Tax Adjustments | Restrictions on Private Residence Relief for homes over £1.5 million under consideration |
Key Points Homeowners Should Know
Higher-value properties, especially in London and the South East, may pay both the £810 base and additional proportional levies
- Lower-value regions may only pay the baseline, making the system more progressive
- Deferred charges for downsizers or retirees could accumulate and become payable upon sale
- Transitional rules will be critical to prevent double taxation for those who have already paid SDLT
Impact on Regions and Homeowners
High-value areas like London and the South East are expected to see the largest tax increases, while regions with lower property values may pay only the base contribution. Homeowners selling after decades could face large deferred charges, emphasizing the need for carefully designed transitional rules. Retirees and downsizers could benefit from deferral options to ease immediate financial pressure.
Administrative and Practical Challenges
Implementing proportional property taxation requires accurate and up-to-date property valuations. The Valuation Office Agency (VOA) would need to modernise its systems, as current Council Tax values are over 30 years old. Appeals, deferral schemes, and safeguards for cash-constrained homeowners are essential. Balancing fairness while ensuring councils receive adequate funding remains a major hurdle for policymakers.
The 2025 property tax reforms represent a major shift in the UK housing landscape. Replacing SDLT with proportional levies and introducing a baseline £810 payment could modernise the system and create a fairer tax structure. However, careful implementation, transitional rules, and clear communication to homeowners will be crucial to its success.
