Stamp Duty Land Tax (SDLT) is a property purchase tax you pay when buying a home or land in England or Northern Ireland. The amount depends on the purchase price, whether you are a first-time buyer, and whether you already own other property. Most buyers pay SDLT in tiered bands, with higher rates on the portion of the price in each band, and relief is available for eligible first-time buyers on properties up to a set threshold.

What is Stamp Duty Land Tax?

SDLT is a tax on property transactions paid to HM Revenue and Customs when you complete a purchase in England or Northern Ireland. According to the official GOV.UK guidance, you pay SDLT if the property costs more than the current threshold, which varies depending on your circumstances (GOV.UK, 2026). Your conveyancing solicitor normally calculates the amount and submits the return within 14 days of completion.

The tax is structured in bands: you pay one rate on the portion of the purchase price within the first band, a higher rate on the portion in the next band, and so on. This means you never pay the top rate on the entire price, only on the amount above each threshold. Scotland and Wales operate separate systems (Land and Buildings Transaction Tax in Scotland, Land Transaction Tax in Wales), so if you are buying property there, different rates and thresholds apply.

First-Time Buyer Relief

First-time buyers in England and Northern Ireland receive SDLT relief on properties below a specified price. As of mid-2026, this relief typically means you pay no SDLT up to a lower threshold and a reduced rate on the portion above it, up to a higher cap. If the property costs more than the upper limit, you pay the standard rates on the entire purchase price and lose the relief.

To qualify, you and anyone you are buying with must be first-time buyers (you have never owned a residential property anywhere in the world), and the property must be your main residence. According to MoneyHelper, verifying your eligibility before exchange helps avoid unexpected costs at completion (MoneyHelper, 2026).

Additional Property Surcharge

If you already own a residential property and are buying another, you pay an additional surcharge on top of the standard SDLT rates. This higher rate applies to the entire purchase price of the additional property. The surcharge is designed to differentiate between those buying a main home and those purchasing second homes or buy-to-let investments.

You may be exempt from the surcharge if you are replacing your main residence (you sell your previous home and buy a new one within a set period), or if the property you already own is worth below a de minimis threshold. The rules are detailed, and timing matters: selling your old home before or shortly after buying the new one can mean the difference between paying the surcharge or claiming it back later.

Check Current Rates and Plan Ahead

SDLT rates, thresholds, and relief limits change with government budgets and policy, so the specific figures for 2026 may differ from prior years. Always check the current rates on the official GOV.UK SDLT page before budgeting for your purchase. As foundational finance texts such as Principles of Finance explain, understanding the tax treatment of major transactions is a core element of responsible financial planning.

When calculating your budget, include SDLT alongside your deposit, conveyancing fees, and mortgage arrangement costs. Your mortgage lender will require you to pay SDLT from your own funds (you cannot add it to your mortgage loan), so factor this into your savings target. If you are a first-time buyer, confirm your eligibility and the current relief threshold; if you are buying an additional property, budget for the higher rate from the start to avoid surprises at completion.

Your home may be repossessed if you do not keep up repayments on your mortgage.
