Understanding SDLT Rate Bands 2025/26

Stamp Duty Land Tax is calculated on a progressive basis, similar to income tax. You only pay the higher rate on the portion of the price within each band:

Price BandStandard RateAdditional Property Rate
Up to £125,0000%5%
£125,001 - £250,0002%7%
£250,001 - £925,0005%10%
£925,001 - £1,500,00010%15%
Over £1,500,00012%17%

First-time buyers: Pay 0% on the first £300,000 and 5% on £300,001 to £500,000. Properties over £500,000 do not qualify for this relief.

£500,000 - £1,000,000 - Higher Value Properties

Properties in this range fall within the 5% SDLT band (up to £925,000) and begin entering the 10% band. First-time buyer relief does not apply above £500,000. The additional property surcharge adds significantly to the total cost at these values.

Over £1,000,000 - Premium Properties

Premium properties attract the highest SDLT rates. Above £925,000, the 10% band applies, and above £1,500,000, the top rate of 12% kicks in. With the additional property surcharge, buyers of second homes at these prices can face total SDLT rates of up to 17% on the portion above £1.5 million.

Stamp Duty FAQs

What is Stamp Duty Land Tax (SDLT)?

Stamp Duty Land Tax is a tax paid when you purchase property or land in England and Northern Ireland above a certain threshold. From April 2025, SDLT applies to residential properties costing more than £125,000 (or £300,000 for first-time buyers). Scotland has its own Land and Buildings Transaction Tax (LBTT) and Wales has Land Transaction Tax (LTT).

What are the current SDLT rates for 2025/26?

For 2025/26, the standard SDLT rates are: 0% on the first £125,000, 2% on £125,001-£250,000, 5% on £250,001-£925,000, 10% on £925,001-£1,500,000, and 12% on amounts over £1,500,000. An additional 5% surcharge applies to second homes and buy-to-let properties on top of these rates.

Do first-time buyers get stamp duty relief?

Yes. First-time buyers pay no SDLT on properties up to £300,000. For properties between £300,001 and £500,000, first-time buyers pay 5% only on the portion above £300,000. Properties over £500,000 do not qualify for first-time buyer relief and standard rates apply instead.

How much is the additional property surcharge?

If you already own a property, buying an additional residential property incurs a 5% surcharge on top of standard SDLT rates. This was increased from 3% to 5% in October 2024. The surcharge applies to buy-to-let properties, second homes, holiday homes, and any additional residential property purchase.

When do I have to pay stamp duty?

SDLT must be paid within 14 days of completion of the property purchase. Your solicitor or conveyancer usually handles the payment and submits the SDLT return to HMRC on your behalf. Late payment may result in penalties and interest charges from HMRC.

Can I add stamp duty to my mortgage?

SDLT cannot be directly added to your mortgage. However, some lenders may allow you to borrow additional funds to cover stamp duty costs, subject to affordability checks and loan-to-value limits. This would increase your overall mortgage amount and monthly repayments. It is generally more cost-effective to pay SDLT from savings where possible.
