Stamp Duty Land Tax (SDLT) is a significant cost when buying property in England and Northern Ireland. Whether you are a first-time buyer stepping onto the property ladder, a homeowner moving up, or an investor expanding your portfolio, understanding your stamp duty liability is essential for budgeting your purchase. Our free Stamp Duty calculator helps you calculate exactly how much SDLT you will pay based on your purchase price, buyer status, and property type.
With recent changes to stamp duty thresholds and reintroduction of first-time buyer relief, it is more important than ever to calculate your liability accurately before making an offer on a property.
What Is Stamp Duty Land Tax (SDLT)?
Stamp Duty Land Tax is a tax paid when you buy property or land over a certain price in England and Northern Ireland. It is a significant transaction cost that must be paid within 14 days of completion. Key features include:
- Progressive Tax: Higher rates apply to portions of price above thresholds
- Buyer Pays: The purchaser is responsible for paying SDLT
- Deadline: Must be paid within 14 days of completion
- Different Rates: Vary by buyer type (first-time, homeowner, investor)
- Property Type: Residential and non-residential have different rates
How Does Stamp Duty Work?
Stamp Duty operates on a progressive band system similar to income tax. You pay increasing rates on portions of purchase price that fall into higher bands.
The Progressive Calculation Method
Unlike a flat percentage, SDLT applies different rates to different portions of price:
£0 - £250,000: £0 (0%)
£250,001 - £400,000: £7,500 (5% of £150,000)
Total SDLT: £7,500
Who Pays Stamp Duty?
The buyer is responsible for paying SDLT and submitting a return to HMRC. Even if no tax is due (under the threshold), a return must usually be filed unless an exemption applies.
The Automatic 14-Day Deadline
You have exactly 14 days from completion to file your SDLT return and pay HMRC. Before 2019, it was 30 days—many buyers still have the old rule in mind.
Missing this deadline triggers an automatic £100 fine, which increases to £200 after 3 months, plus interest on the unpaid tax. Your solicitor usually handles this, but the legal responsibility is yours.
3% Surcharge: The 36-Month Refund Window
If you buy a new home but haven't sold your old one yet, you must pay the "Additional Property" 3% surcharge upfront. This can add tens of thousands to your move-in cost.
The Good News: If you sell your previous main residence within 36 months of buying the new one, you can claim a full refund of that 3% surcharge from HMRC. Don't forget to file the claim!
Shared Ownership: The "Election" Dilemma
When buying a shared ownership property, you have two choices: Pay SDLT on the Full Market Value now, or pay only on the Share you are buying.
The Strategy: If you plan to "staircase" to 100% ownership later and property prices are rising, paying the full SDLT now is often cheaper. If you plan to move in a few years, paying on the share saves you cash upfront.
Non-Resident 2% Surcharge Refund
If you are not "present" in the UK for at least 183 days in the 12 months before purchase, you are hit with a 2% non-resident surcharge.
The Refund Hack: if you move to the UK and stay for 183 days in any continuous 365-day period starting from 1 year before purchase to 1 year after, you may be eligible to claim that 2% back. It’s a common win for expats returning home.

First-Time Buyer Eligibility
To qualify for first-time buyer relief, you and any joint purchasers must never have owned a property anywhere in the world. The property must be your main residence, and the purchase price must be £625,000 or less.
Additional Property Rates (Second Homes, Buy-to-Let)
A 3% surcharge applies to the entire purchase price when buying additional residential properties:
| Portion of Property Price | SDLT Rate |
|---|---|
| Up to £250,000 | 3% |
| £250,001 to £925,000 | 8% |

First-Time Buyer Relief Explained
The first-time buyer relief provides significant savings for those getting on the property ladder:
Relief Benefits
- Zero SDLT on purchases up to £425,000
- Reduced rates on purchases up to £625,000
- No relief available above £625,000
Who Qualifies?
To qualify as a first-time buyer:
- You must never have owned a property anywhere in the world
- Includes inherited properties and properties owned overseas
- All joint purchasers must be first-time buyers
- Property must be your main residence
- You must occupy the property as your main home
First-Time Buyer Example - £500,000 Property
Scenario: James buys his first home for £500,000.
- £0 - £425,000: £0 (0%)
- £425,001 - £500,000: £3,750 (5% of £75,000)
- Total SDLT: £3,750
Without first-time buyer relief, James would pay £12,500 (£250,000 x 0% + £250,000 x 5%). He saves £8,750.
Additional Property Surcharge
If you buy a property and already own one or more properties, you may pay the additional property surcharge.
When the Surcharge Applies
The 3% surcharge applies if:
- You already own a residential property anywhere in the world
- The new property is not replacing your main residence
- You are buying a buy-to-let investment
- You are buying a second home or holiday property
Replacing Your Main Residence
If you are selling your main home and buying a new one, the surcharge does not apply, even if you own other properties (like buy-to-lets). However, if you buy before you sell, you pay the surcharge initially but can claim a refund if you sell your previous main residence within 3 years.
Non-Resident Stamp Duty Surcharge
A 2% surcharge applies to purchases by non-UK residents. This is in addition to any other surcharges (like the 3% additional property surcharge).
Who Is a Non-Resident?
You are non-resident for SDLT if you have not been present in the UK for at least 183 days (6 months) in the 12 months before the purchase date.
Combined Surcharges
A non-resident buying an additional property could pay:
- Standard SDLT rates
- + 3% additional property surcharge
- + 2% non-resident surcharge
For a £400,000 investment property: Up to 10% on portions of the price (3% + 2% + 5% standard rate).
Stamp Duty Exemptions & Reliefs
Several situations qualify for SDLT exemptions or reduced rates:
Common Exemptions
- No Consideration: Property transferred as a gift (no money changes hands)
- Divorce/Dissolution: Property transfers between separating couples
- Inheritance: Property inherited under a will
- Charities: Purchases by registered charities
- Registered Social Landlords: Certain housing association purchases
Multiple Dwellings Relief (MDR)
If you buy multiple properties in one transaction, you can calculate SDLT based on the average price per property rather than the total, potentially reducing your bill.
Relief for Employers
Employers providing staff accommodation may qualify for relief.
Shared Ownership Property
Shared ownership has special SDLT rules:
- Staircasing: When you increase your share, SDLT may apply to the additional purchase
- Market Value Option: You can choose to pay SDLT based on the full market value or your share
- First-Time Buyer Relief: Available for qualifying shared ownership purchases
Shared Ownership Example
If you buy a 50% share of a £300,000 property as a first-time buyer (£150,000 share), SDLT may be lower. However, if you later staircase to 100% ownership, you may pay additional SDLT on the increased share.

The table below compares the key features of property transfer taxes across five major markets.
| Country | Tax Name | Typical Rate Range | First-Time Buyer Relief | Who Pays |
|---|---|---|---|---|

Frequently Asked Questions About Stamp Duty
Stamp duty rates vary by purchase price and buyer type. For standard residential purchases: 0% up to £250,000, 5% on £250,001-£925,000, 10% on £925,001-£1,500,000, and 12% above £1,500,000. First-time buyers pay 0% up to £425,000. Additional properties attract a 3% surcharge on the entire price.
First-time buyers pay no stamp duty on purchases up to £425,000. For properties between £425,001 and £625,000, they pay 5% on the amount above £425,000. No first-time buyer relief exists above £625,000. To qualify, you must never have owned property anywhere in the world.
Stamp duty must be paid within 14 days of the completion date (when you get the keys). Your solicitor or conveyancer typically files the return and pays the tax on your behalf, but you are legally responsible for ensuring it is paid on time. Late payment incurs penalties and interest.
Yes, second homes and buy-to-let properties attract a 3% surcharge on top of standard rates. This applies to the entire purchase price. For example, a £300,000 second home incurs £11,500 SDLT (3% on first £250,000 = £7,500, plus 8% on £50,000 = £4,000). If replacing your main residence, the surcharge does not apply.
Technically some lenders may allow you to borrow extra to cover SDLT, but this is generally not recommended. Adding SDLT to your mortgage means paying interest on it over 25-30 years, significantly increasing the total cost. It is better to save for SDLT separately alongside your deposit.
The standard SDLT threshold is £250,000 - you pay no SDLT on the first £250,000 of a property purchase. For first-time buyers, the threshold is £425,000. Above these thresholds, progressive rates apply to portions of the price in different bands.
Yes, non-UK residents pay a 2% surcharge on residential property purchases in England and Northern Ireland. This applies if you have not been present in the UK for 183 days in the 12 months before purchase. This surcharge is in addition to any other charges (like the 3% additional property surcharge).
Yes, different systems apply. Scotland uses Land and Buildings Transaction Tax (LBTT) with different rates and thresholds. Wales uses Land Transaction Tax (LTT). Both have their own first-time buyer relief and additional property surcharge rules. Our calculator includes options for all three systems.
You can claim a refund of the 3% additional property surcharge if you sell your previous main residence within 3 years of buying your new one. You must apply for the refund within 12 months of selling your old home or within 12 months of filing date for the new property return, whichever is later.
For shared ownership properties, you can choose to pay SDLT either on the share you are buying or on the full market value. If you pay on the share only, you may pay more SDLT later when staircasing to full ownership. First-time buyer relief applies to shared ownership if you meet the criteria.
Failure to pay SDLT on time results in automatic penalties and interest charges. Penalties start at £100 for returns up to 3 months late, increasing to £200 after 3 months, plus interest on the unpaid tax. HMRC can take legal action to recover unpaid SDLT.
No stamp duty is payable when you inherit a property under a will or intestacy rules. However, if you buy a property from an estate (not inherit it), SDLT applies. Inheritance tax may apply instead on the estate's value above the threshold.
Buying through a company generally does not reduce SDLT and may increase it. Companies face a 15% rate for residential properties over £500,000 unless the property is used for a property development or rental business. Annual Tax on Enveloped Dwellings (ATED) also applies. Seek specialist tax advice before using a company structure.
Yes, but commercial SDLT rates are different from residential. Commercial and mixed-use properties have lower rates: 0% up to £150,000, 2% on £150,001-£250,000, and 5% above £250,000. No first-time buyer relief or additional property surcharge applies to commercial property.
SDLT rates are set by the government and can change with each Budget (usually March and sometimes November/Autumn statements). Recent years have seen several changes including temporary holidays during COVID-19 and permanent changes to thresholds and first-time buyer relief. Always check current rates before budgeting for a purchase.
