How Much Stamp Duty Will I Pay?
Buying a property is an exciting milestone, but Stamp Duty Land Tax (SDLT) can add thousands to your budget. City Realtor explains everything you need to know to plan ahead and budget with confidence.
What Is Stamp Duty?
Stamp Duty Land Tax is a government tax paid when purchasing property or land in England and Northern Ireland. The amount you pay depends on the property’s purchase price, your buyer status (first-time, homeowner, investor), and whether you are a UK resident. It applies whether you’re buying with a mortgage or outright. The payment must be made to HMRC within 14 days of completing the purchase.
In Scotland, buyers pay Land and Buildings Transaction Tax (LBTT), and in Wales, the equivalent is Land Transaction Tax (LTT).
Stamp Duty Thresholds and Rates (2025 Update)
- Up to £250,000 – 0%
- £250,001 – £925,000 – 5%
- £925,001 – £1.5 million – 10%
- Over £1.5 million – 12%
Example: If you purchase a home for £600,000: 0% on the first £250,000 = £0; 5% on the next £350,000 = £17,500; Total stamp duty: £17,500.
First-Time Buyers – What You’ll Pay
To support people getting onto the property ladder, the government offers stamp duty relief for first-time buyers:
- No stamp duty on properties up to £425,000
- 5% on the portion between £425,001 and £625,000
- If the property costs more than £625,000, no relief applies
Example: A first-time buyer purchasing a £500,000 property pays 0% on the first £425,000 = £0; 5% on £75,000 = £3,750; Total stamp duty: £3,750. To qualify, you must have never owned property before anywhere in the world.
Buying an Additional Property – Higher Rate Applies
If you already own a property and are buying another (e.g., a second home or buy-to-let investment), you will pay a 3% surcharge on top of the standard rates. This applies whether the additional property is in the UK or abroad.
Example: Buying a £400,000 second home: 0% base rate + 3% surcharge on first £250,000 = £7,500; 5% base rate + 3% surcharge on next £150,000 = £12,000; Total stamp duty: £19,500. You may be able to reclaim the surcharge if you sell your original property within 36 months.
Overseas Buyers – Non-Resident Surcharge
Non-UK residents must pay an extra 2% on top of standard stamp duty rates. This applies if you’ve spent fewer than 183 days in the UK in the 12 months prior to your purchase. If you’re also buying a second property, you could face up to 5% in combined surcharges.
- Careful timing of your residency status
- Working with a solicitor familiar with non-resident tax
- Understanding how surcharges affect buy-to-let investments
- Factoring total costs into financing plans
- Confirming tax status if buying with a UK partner
Commercial and Mixed-Use Property Stamp Duty
- Up to £150,000 – 0%
- £150,001 – £250,000 – 2%
- Over £250,000 – 5%
Mixed-use properties often benefit from these lower rates, making them a tax-efficient option for some investors.
How to Estimate Your Stamp Duty
- Identify the relevant rate bands and surcharges for your situation
- Break your purchase price into sections that match those bands
- Apply the corresponding rate to each portion
- Add the values together for your total liability
- Double-check with a reputable stamp duty calculator tool
City Realtor offers access to up-to-date digital tools to help you calculate quickly and accurately.
What Affects Your Stamp Duty Liability?
- Property Type: Residential, commercial or mixed-use
- Ownership Status: First or additional property
- Buyer Status: UK resident, overseas investor, or buying with someone else
- Use of Property: Primary residence, rental, holiday home, or corporate purchase
- Reliefs and Exemptions: Including first-time buyer relief and transfer exemptions
These variables mean that two buyers purchasing identical properties may owe very different amounts.
Legal Obligations and Payment Timeline
Stamp duty is legally due within 14 days of the transaction's completion. Your solicitor usually handles the filing and payment on your behalf. Failing to pay on time can lead to interest charges and penalties from HMRC. Even if you qualify for relief or exemption, you must still submit a return in most cases.
Can You Reduce Your Stamp Duty?
- Choose mixed-use or commercial property for lower rates
- Buy jointly with a first-time buyer to access reliefs (with caution)
- Time your residency if you are an overseas buyer planning relocation
- Consider properties just under a threshold to avoid surcharges
- Investigate any applicable government schemes or incentives
Always consult an experienced estate agent or solicitor before making a decision based on tax strategy.
