As a First-Time Buyer, you currently pay 0% up to £425k. In 2025/2026, this threshold drops back to £300k. If you complete after March 2025, you will be hit with an unexpected tax bill.

The Return of the £125k Threshold

The UK housing market is facing a significant cliff-edge. The temporary Stamp Duty Land Tax (SDLT) thresholds introduced a few years ago are legally set to expire at the end of March 2025.

This means that from April 2025 onwards, the standard nil-rate band drops from £250,000 to £125,000. This instantly adds £2,500 to the cost of moving home for the average buyer.

For First-Time Buyers, the blow is even harder. The FTB exemption threshold is plummeting from £425,000 to £300,000, wiping out up to £6,250 in tax savings.

Stamp Duty FAQs

What is the Stamp Duty cliff edge in 2025/2026?
The temporary Stamp Duty cuts are ending in March 2025. The standard nil-rate band will drop from £250,000 to £125,000, meaning almost all buyers will pay an extra £2,500 in tax.
Are First-Time Buyers affected by the 2026 changes?
Yes, significantly. The First-Time Buyer nil-rate threshold is dropping from £425,000 back down to £300,000. If you buy a house over £300,000 after March 2025, you will have to pay thousands in Stamp Duty that you previously wouldn't have.
What is the new second home surcharge?
As announced in the October 2024 budget, the Stamp Duty surcharge for purchasing an additional dwelling (like a buy-to-let or second home) has increased from 3% to 5%.
When exactly do the old rates return?
The temporary higher thresholds expire on 31 March 2025. Any property purchases completing on or after 1 April 2025 will be subject to the old, more expensive rates.
