Understanding SDLT in 2025: A Friendly Guide for UK Property Buyers

Whether you're stepping onto the property ladder for the first time, expanding your portfolio, or purchasing through a limited company, understanding Stamp Duty Land Tax (SDLT) is crucial. With recent changes effective from April 1, 2025, it's more important than ever to be informed. Let's break it down together.


What is SDLT and Why Should You Care?

Stamp Duty Land Tax (SDLT) is a tax you pay when buying property or land in England or Northern Ireland. The amount depends on the property's price and your buyer status—first-time buyer, additional property owner, or company purchaser.

Key Changes from April 1, 2025:

  • The nil-rate threshold for residential properties has decreased from £250,000 to £125,000.

  • For first-time buyers, the threshold has reduced from £425,000 to £300,000.

  • The maximum purchase price eligible for first-time buyer relief has lowered from £625,000 to £500,000.

  • The surcharge for additional properties has increased from 3% to 5%.

These changes aim to balance the housing market but may impact your purchasing decisions.


1. SDLT for First-Time Buyers

If you're buying your first home, congratulations! The government offers relief to help you get started.

What Is First-Time Buyer SDLT Relief?

Stamp Duty Land Tax (SDLT) relief is available if you’re a first-time buyer purchasing a residential property in England or Northern Ireland. The relief is intended to ease the financial pressure of buying your first home by reducing (or even eliminating) the SDLT bill.

To qualify, you must:

  • Have never owned residential property anywhere in the world.

  • Be buying a main residence, not a buy-to-let.

First-Time Buyer Relief (as of April 1, 2025)

  • No SDLT on properties up to £300,000.

  • For properties priced between £300,001 and £500,000, a 5% SDLT applies to the portion above £300,000.

  • No relief for properties over £500,000.

Example:

  • Property Price: £350,000

  • SDLT: 5% on £50,000 = £2,500

Note: You must be a genuine first-time buyer, meaning you've never owned property anywhere in the world.

2. SDLT for Additional Properties

If you're purchasing an additional property—like a buy-to-let or holiday home—you'll face higher SDLT rates.

Example:

  • Property Price: £300,000

  • Standard SDLT: £2,500

  • Additional Property Surcharge: £15,000

  • Total SDLT: £17,500

Tip: If you're replacing your main residence and sell your previous home within 36 months, you may be eligible for a refund of the additional surcharge.

If you're purchasing a buy-to-let and wondering how SDLT and tax changes like mortgage interest relief affect your bottom line, don’t miss our explainer on Section 24 – What It Means for UK Property Investors (With Examples). It’s a must-read for landlords in 2025.


3. SDLT for Limited Companies

Purchasing property through a limited company can offer tax advantages, but SDLT rates are higher.

Buying property through a limited company offers tax planning advantages, but it comes with different SDLT rules. From April 2025, companies pay higher SDLT rates across the board — including a flat 15% charge for high-value residential properties in some cases. In this section, we explain how SDLT applies to limited companies, what to watch for with the £500,000 threshold, and how to structure purchases to stay compliant and tax-efficient.

Limited Company SDLT Rates (as of April 1, 2025)

Example:

  • Property Price: £500,000

  • SDLT: Calculated as follows:

    • 5% on first £125,000 = £6,250

    • 7% on next £125,000 = £8,750

    • 10% on remaining £250,000 = £25,000

    • Total SDLT: £40,000

Note: Properties purchased by companies over £500,000 may be subject to a 15% flat rate unless certain conditions are met.

Buying through a limited company comes with SDLT implications, but it could offer long-term tax advantages. If you're unsure whether to invest through a company or personally, check out our detailed guide: Limited Company vs Personal Name – Which Is Best for Property Investment?


How to Pay SDLT

Your solicitor or conveyancer typically handles the SDLT return and payment. However, it's your responsibility to ensure it's paid within 14 days of completion.

  • Deadline: 14 days post-completion

  • Payment: Through your solicitor or directly via HMRC's website

Late Payment Consequences:

  • Interest charges

  • Penalties starting at £100, increasing with time


Summary: Key SDLT Takeaways

  • First-Time Buyers: No SDLT up to £300,000; 5% on £300,001–£500,000.

  • Additional Properties: 5% surcharge on top of standard rates.

  • Limited Companies: Higher SDLT rates apply; potential 15% flat rate for properties over £500,000.
