How It Works: SDLT Rates for 2025
Stamp Duty is charged on property purchases above £250,000 (or £425,000 for first-time buyers). It's calculated in bands—you pay different rates on different portions of the price:
Standard Residential Rates (2025):
First-Time Buyer Rates (properties up to £625,000):
Additional Property Surcharge: +3% on all bands for second homes and buy-to-let purchases.

Key Factors to Consider
1. First-Time Buyer Relief Has Limits
The relief only applies to properties up to £625,000. If you pay £625,001 or more, you lose all first-time buyer benefits and pay standard rates on the entire price. This cliff edge can make a £625,000 property cheaper than a £650,000 one after SDLT.
2. Second Home Surcharge Is Significant
The 3% additional rate applies to anyone buying an additional residential property worth over £40,000. This includes buy-to-let investors, holiday home buyers, and anyone who hasn't sold their previous main residence before completion.
3. SDLT Must Be Paid Within 14 Days
SDLT is due within 14 days of completion. Your conveyancing solicitor usually handles the payment and filing, but the legal liability is yours. Late payments incur automatic penalties and interest.
4. Scotland and Wales Have Different Taxes
Scotland uses Land and Buildings Transaction Tax (LBTT), and Wales uses Land Transaction Tax (LTT). Rates and thresholds differ from England/Northern Ireland SDLT. Our calculator supports all UK nations.
Frequently Asked Questions
How much stamp duty will I pay on a £300,000 house?
First-time buyers pay £0 on a £300,000 property (under the £425,000 threshold). Standard buyers pay £2,500 (5% on £50,000 above the £250,000 nil-rate band). Second home buyers pay £11,500 (£2,500 base + 3% surcharge on full price).
Do first-time buyers pay stamp duty in 2025?
First-time buyers pay no stamp duty on properties up to £425,000. For properties between £425,000 and £625,000, they pay 5% only on the portion above £425,000. Above £625,000, standard rates apply with no relief.
What is the stamp duty surcharge for second homes?
An additional 3% is added to each SDLT band when purchasing a second home, buy-to-let property, or any additional residential property over £40,000. This applies on top of standard rates at every price level.
Can I avoid stamp duty legally?
You can reduce SDLT by negotiating a lower purchase price, buying as first-time buyers if eligible, or timing purchases around rate changes. You cannot avoid SDLT through artificial schemes—HMRC actively challenges these arrangements.
When is stamp duty due after buying a house?
SDLT must be paid within 14 days of completion (the day you legally become the owner). Your solicitor typically submits the return and payment to HMRC on your behalf as part of the conveyancing process.
