Stamp Duty for First-Time Buyers in the UK: What You Need to Know (2025)

Buying your first home is one of the biggest financial decisions you'll ever make. Alongside the deposit, mortgage, and solicitor fees, stamp duty is one of the key costs to factor into your budget — yet it's often misunderstood or forgotten until close to completion.

This guide explains how stamp duty works for first-time buyers in England and Northern Ireland in 2025, with worked examples to help you see exactly what you'll pay.

What Is Stamp Duty?

Stamp Duty Land Tax (SDLT) is a tax paid to HMRC when you buy a property or land in England or Northern Ireland above a certain threshold. It's calculated as a percentage of the purchase price and must be paid within 14 days of completion.

In Scotland, the equivalent is Land and Buildings Transaction Tax (LBTT), administered by Revenue Scotland. In Wales, it's called Land Transaction Tax (LTT), administered by the Welsh Revenue Authority. The rates and thresholds differ across all three nations — this guide focuses on England and Northern Ireland.

First-Time Buyer Stamp Duty Relief

First-time buyers in England and Northern Ireland benefit from Stamp Duty relief, which reduces or eliminates the SDLT bill on lower-value properties.

From 1 April 2025 onwards (thresholds as they stand in 2025):

£0 – £300,000: 0% (no SDLT)
£300,001 – £500,000: 5% on the portion above £300,000
Above £500,000: No first-time buyer relief applies — standard rates are charged on the full purchase price

Important note on the March 2025 threshold change: Temporary thresholds introduced in September 2022 expired on 31 March 2025. From 1 April 2025, the standard nil-rate threshold reverted from £250,000 to £125,000, and the first-time buyer nil-rate threshold reverted from £425,000 to £300,000. The upper limit for first-time buyer relief also dropped from £625,000 to £500,000. If you completed your purchase before 31 March 2025, the higher thresholds applied to you.

How Much Stamp Duty Will You Pay? Worked Examples

Example 1: Buying at £250,000

£0 – £300,000 for first-time buyers: 0%
Total SDLT: £0

At £250,000, a first-time buyer pays nothing — the property falls entirely within the nil-rate band.

Example 2: Buying at £400,000

£0 – £300,000: 0% = £0
£300,001 – £400,000 (£100,000 at 5%): £5,000
Total SDLT: £5,000

Example 3: Buying at £500,000

£0 – £300,000: 0% = £0
£300,001 – £500,000 (£200,000 at 5%): £10,000
Total SDLT: £10,000

Example 4: Buying above £500,000 (no relief)

If a first-time buyer purchases a property above £500,000, first-time buyer relief does not apply at all. Standard SDLT rates apply on the full purchase price:

£0 – £125,000: 0%
£125,001 – £250,000: 2%
£250,001 – £925,000: 5%

On a £600,000 purchase, for example:

£0 – £125,000: £0
£125,001 – £250,000 (£125,000 at 2%): £2,500
£250,001 – £600,000 (£350,000 at 5%): £17,500
Total SDLT: £20,000

This is why first-time buyers are typically advised to target properties below £500,000 wherever possible.

Scotland (LBTT) and Wales (LTT): A Brief Overview

Scotland — Land and Buildings Transaction Tax (LBTT): First-time buyers in Scotland benefit from the First Home Fund relief. The nil-rate threshold for first-time buyers is currently £175,000. Rates above that apply incrementally. Check Revenue Scotland's website for current rates.

Wales — Land Transaction Tax (LTT): Wales does not currently offer a first-time buyer-specific relief — the standard LTT rates apply to all buyers. The nil-rate threshold in Wales is £225,000. Check the Welsh Revenue Authority website for current rates.

How to Claim First-Time Buyer Relief

You don't need to do anything beyond informing your solicitor or conveyancer that you are a first-time buyer. They will:

Complete the SDLT return on your behalf
Apply the first-time buyer relief automatically
Pay any SDLT owed to HMRC on the day of completion (or within 14 days)

SDLT is not something you'll deal with directly — it's handled entirely as part of the conveyancing process.

To qualify as a first-time buyer, you must:

Never have owned a residential property before (in the UK or abroad)
Be purchasing the property as your main residence
Be buying with a mortgage or in cash — the relief applies either way

If you're buying jointly, both buyers must be first-time buyers for the relief to apply.

Factor Stamp Duty Into Your Budget Early

One of the most common mistakes first-time buyers make is treating stamp duty as an afterthought. At £400,000, you'll owe £5,000 in SDLT — money that must be available on completion day.

Other upfront costs to budget for alongside stamp duty:

Solicitor / conveyancer fees: £1,000–£2,500
Mortgage arrangement fee: £0–£2,000 (sometimes added to mortgage)
Survey: £300–£1,500 depending on type
Removal costs: £300–£2,000+

Build these into your total budget from the outset, not after you've made an offer.
