Upcoming Stamp Duty Changes: What UK Homebuyers Need to Know Post 1st April 2025

As the 1st of April 2025 approaches, significant changes to Stamp Duty Land Tax (SDLT) are set to take effect, impacting both first-time buyers and existing homeowners across the UK. Understanding these changes is vital for anyone considering purchasing property in the near future or currently purchasing.

The rules are different for First-Time Buyers compared to all other Homebuyers. From 1st April 2025, Stamp Duty thresholds will be reduced, meaning first-time buyers will pay tax on properties above £300,000 instead of £425,000. Standard homebuyers will also see the 0% threshold drop from £250,000 to £125,000, increasing overall tax liabilities. We have set out some examples below.  

Current Stamp Duty Rates vs. Post-April 2025 Rates

For First-Time Buyers:

• Until 31st March 2025:
• No SDLT on properties up to £425,000.
• 5% SDLT on the portion from £425,001 to £625,000.
• Properties over £625,000 do not qualify for relief.

Example: Purchasing a property at £500,000:

• 0% on the first £425,000 = £0
• 5% on the remaining £75,000 = £3,750
• Total SDLT = £3,750

• From 1st April 2025:
  • No SDLT on properties up to £300,000.
  • 5% SDLT on the portion from £300,001 to £500,000.
  • Properties over £500,000 do not qualify for relief.

Example: Purchasing a property at £500,000:

• 0% on the first £300,000 = £0
• 5% on the remaining £200,000 = £10,000
• Total SDLT = £10,000

For All Other Homebuyers:

• Until 31st March 2025:
• 0% on the first £250,000
• 2% on the portion from £250,001 to £925,000
• 10% on the portion from £925,001 to £1.5 million
• 12% on the portion above £1.5 million

• From 1st April 2025:
  • 0% on the first £125,000
  • 2% on the portion from £125,001 to £250,000
  • 5% on the portion from £250,001 to £925,000
  • 10% on the portion from £925,001 to £1.5 million
  • 12% on the portion above £1.5 million

Example: Purchasing a property at £295,000:

• 0% on the first £125,000 = £0
• 2% on the next £125,000 = £2,500
• 5% on the remaining £45,000 = £2,250
• Total SDLT = £4,750

Implications for Homebuyers

The upcoming Stamp Duty Land Tax (SDLT) changes will significantly impact first-time buyers, so it’s important to examine and understand the full realities of these changes. Here are some key facts to consider:

Increased Upfront Costs

With the tax-free threshold for first-time buyers dropping from £425,000 to £300,000, those purchasing properties above this limit will face higher tax liabilities. For example, a first-time buyer purchasing a £400,000 home before April 2025 would pay £0 in SDLT, whereas after the changes, they would owe £5,000. This additional financial burden could delay homeownership for many. 

Affordability Struggles and Mortgage Implications

As the 1st of April 2025 approaches, significant changes to Stamp Duty Land Tax (SDLT) are set to take effect, impacting both first-time buyers and existing homeowners across the UK. Understanding these changes is vital for anyone considering purchasing property in the near future or is in the process of purchasing right now. 

Higher SDLT costs mean first-time buyers may need to increase their savings for upfront expenses, potentially reducing their deposit size. A lower deposit often results in higher mortgage interest rates, making monthly repayments more expensive. With affordability already stretched due to rising house prices and interest rates, it could be harder for buyers to secure a mortgage so adjust and plan accordingly.

Potential Market Slowdown and Increased Competition

If fewer first-time buyers can afford to enter the market due to higher SDLT costs, there may be reduced demand for entry-level homes. Conversely, those rushing to buy before April 2025 may create short-term competition, leading to inflated house prices in early 2025 before a potential slowdown post-April. 

Longer Savings Period and Delayed Homeownership

With the additional tax burden, first-time buyers may need to save for longer before they can afford to buy. This could lead to increased demand for rental properties, potentially driving up rental costs and making it even harder for aspiring homeowners to save. 

Limited Impact of SDLT Relief for Higher-Priced Properties 

First-time buyers purchasing homes up to £625,000 can still benefit from SDLT relief. However, after April 2025, properties above £500,000 will not qualify for any SDLT relief, significantly increasing costs for buyers in areas with high property values, such as London and the South East. 

These changes mean first-time buyers will need to carefully assess their budgets, mortgage options, and potential purchase timelines to effectively navigate the shifting landscape.

Current Housing Market Overview and 2025 Predictions

As of early 2025, the UK housing market has experienced a modest annual price growth of 1.9%, with the average property valued at £267,200. This growth indicates a stabilisation following the rapid increases observed in previous years.

Looking ahead, experts anticipate continued growth in property values. For instance, Savills has revised its five-year UK forecast upward from 17.9% to 21.6%, suggesting a more balanced distribution of growth over this period. Similarly, Nationwide projects house price growth between 2% and 4% for 2025, reflecting resilience despite ongoing affordability challenges.
