- The average UK house price is approximately £290,000 (ONS, December 2025), meaning many FTBs still pay zero SDLT
- Additional property buyers face a 5% surcharge on every band, adding thousands to the bill
- HMRC collected £13.9 billion in SDLT receipts in FY2024-25, showing the scale of this tax on the UK economy
- Budget for solicitor fees (£1,000-£2,500), survey (£250-£1,500), and Land Registry (£45-£910) alongside SDLT
- Always calculate your total purchase costs before starting your property search to avoid being caught short at completion

Why Budget for Stamp Duty?
Stamp Duty Land Tax (SDLT) is a transaction tax charged by HMRC on all property purchases in England and Northern Ireland above certain thresholds. Under the Finance Act 2003 ss43-55, SDLT is calculated progressively on the purchase price, with each rate band applying only to the portion of price within that band — similar to how income tax works. Use our stamp duty calculator to get an instant, accurate figure for your situation.
HMRC collected £13.9 billion in SDLT receipts in FY2024-25, demonstrating just how significant this tax is for buyers across England and Northern Ireland. For most buyers, SDLT is the second largest upfront cost after the deposit — yet many start their property search without having budgeted for it. This can lead to serious problems at completion when funds fall short.
The average UK house price is approximately £290,000 according to ONS data for December 2025. At this price, a standard buyer pays £3,300 in SDLT, while a first-time buyer pays nothing. Understanding your likely SDLT bill before you start searching is essential — it directly affects how much you can afford to offer and what you need in cash reserves.
HMRC Manual Reference: SDLTM00100
SDLTM00100 sets out the basic principles of SDLT. The tax is chargeable on the acquisition of a chargeable interest in land where the chargeable consideration exceeds the nil-rate threshold. Finance Act 2003 ss43-55 governs the progressive band calculation.
Current SDLT Rate Bands (2026)
Following the April 2025 threshold reversion, the standard SDLT rates for residential property in England and Northern Ireland are as follows:
| Purchase Price Band | Standard Rate | FTB Rate | Additional Dwelling |
|---|---|---|---|
| Up to £125,000 | 0% | 0% | 5% |
| £125,001 to £250,000 | 2% | 0% | 7% |
| £250,001 to £300,000 | 5% | 0% | 10% |
| £300,001 to £500,000 | 5% | 5% | 10% |
| £500,001 to £925,000 | 5% | 5% (standard) | 10% |
| £925,001 to £1,500,000 | 10% | 10% | 15% |
| Above £1,500,000 | 12% | 12% | 17% |
FTB relief applies to properties up to £500,000. Above that, standard rates apply. Additional dwelling surcharge applies from the first pound.
SDLT Worked Examples at Key Price Points
The following table shows the SDLT due at four common price points for three buyer types. All figures are for England and Northern Ireland in 2026.
| Property Price | Standard Buyer | First-Time Buyer | Additional Property |
|---|---|---|---|
| £200,000 | £1,500 | £0 | £11,500 |
| £300,000 | £5,000 | £0 | £20,000 |
| £400,000 | £10,000 | £5,000 | £30,000 |
| £500,000 | £12,500 | £10,000 | £37,500 |
£300,000 Standard Buyer — Calculation Breakdown
- 0% on first £125,000 = £0
- 2% on £125,001-£250,000 (£125,000) = £2,500
- 5% on £250,001-£300,000 (£50,000) = £2,500
- Total SDLT = £5,000
£400,000 First-Time Buyer — Calculation Breakdown
- 0% on first £300,000 = £0 (FTB nil-rate band)
- 5% on £300,001-£400,000 (£100,000) = £5,000
- Total SDLT = £5,000
£500,000 Additional Property — Calculation Breakdown
- 5% on first £125,000 = £6,250
- 7% on £125,001-£250,000 (£125,000) = £8,750
- 10% on £250,001-£500,000 (£250,000) = £25,000
- Total SDLT = £40,000
First-Time Buyer Advantages
First-time buyer relief under Finance Act 2003 s57AA provides a significantly higher nil-rate band for qualifying buyers. Following the April 2025 threshold reversion, first-time buyers pay 0% on the first £300,000 and 5% on the portion between £300,001 and £500,000. Above £500,000, FTB relief does not apply and standard rates take effect.
Both buyers must qualify as first-time buyers in a joint purchase. A first-time buyer is someone who has never owned a freehold or leasehold interest in a residential property anywhere in the world. Use our first-time buyer stamp duty guide for full eligibility rules.
Maximum FTB saving at different prices
- At £250,000: FTB saves £2,500 vs standard (£0 vs £2,500)
- At £300,000: FTB saves £5,000 vs standard (£0 vs £5,000)
- At £400,000: FTB saves £5,000 vs standard (£5,000 vs £10,000)
- At £500,000: FTB saves £2,500 vs standard (£10,000 vs £12,500)
The savings are front-loaded at lower price points because the extended nil-rate band delivers the most benefit on properties where the standard 2% band would otherwise apply. At £500,000, the saving narrows because only the FTB extended nil-rate band (above £300,000) provides an advantage, which is offset by both buyers paying 5% on the £300,001-£500,000 band at the same rate as standard buyers.
Additional Property Surcharge Impact
Buyers purchasing an additional residential property — including buy-to-let investments and second homes — pay a 5% surcharge on every SDLT band, from the first pound. This surcharge was introduced by Finance Act 2016 and increased from 3% to 5% in April 2025. The resulting tax bills are significantly higher and must be budgeted carefully.
Surcharge applies from the first pound
Unlike the standard nil-rate band, the 5% surcharge has no nil-rate threshold. A £200,000 additional property purchase incurs £11,500 SDLT (£10,000 surcharge plus £1,500 standard). This must come from your own funds and cannot be borrowed via mortgage.
A 36-month refund window exists if you sell your previous main residence within 36 months of completing your new purchase. This can return the surcharge element if your purchase was intended as a main residence replacement that was delayed. See offer price and stamp duty bands for strategic considerations around pricing.

Budgeting Checklist for House Hunters
Before starting your property search in earnest, work through this checklist to ensure your finances are properly planned:
- Confirm your buyer status: standard, first-time buyer, or additional property
- Set your maximum offer price and calculate SDLT at that price using our calculator
- Add solicitor fees (budget £1,500+VAT as a starting point), survey (£500), and searches (£350)
- Confirm your deposit percentage and verify it leaves enough cash for SDLT and fees
- Check whether a Lifetime ISA applies and factor in the 12-month holding requirement
- Speak to your mortgage broker to confirm affordability including all upfront costs
- Recalculate at £50,000 intervals within your search range so you know how costs change
- Set aside a contingency of £1,000-£2,000 for unexpected costs (re-surveys, abortive transactions)
Common Budgeting Mistakes
Forgetting SDLT on leasehold purchases
Buying a new leasehold property with a ground rent can trigger SDLT on the net present value of the rent as well as the premium. This can add several thousand pounds to the bill on long leases with significant ground rent. Always tell your solicitor if you are buying leasehold.
Assuming SDLT can be added to the mortgage
SDLT cannot be incorporated into a residential mortgage. It must be paid from your own verified funds. Some buyers discover this only at the mortgage offer stage, leaving them short at completion.
Not recalculating when the offer price changes
If a seller accepts a lower offer — say £298,000 instead of £305,000 — the SDLT position changes significantly for a first-time buyer (from £0 to potentially a small saving). Always recalculate when the agreed price changes.
Ignoring the additional dwelling surcharge on replacement homes
If you own an existing property and buy a new one before selling the old one, you will initially pay the 5% surcharge. If you sell the old property within 36 months, you can claim a refund. Budget for the full surcharge until the old property is sold.

Calculate your stamp dutyFrequently Asked Questions
How much should I budget for stamp duty?
It depends on the property price and your buyer status. First-time buyers pay nothing up to £300,000. Standard buyers pay SDLT from £125,001 — on a £300,000 purchase that is £5,000. Use our stamp duty calculator for exact figures based on your situation and buyer type.
Is stamp duty the biggest cost when buying?
After the deposit, yes. On a £350,000 home, a standard buyer pays £3,750 SDLT versus approximately £1,500 for solicitor fees and approximately £500 for a survey. SDLT is typically the single largest additional upfront cost beyond the deposit.
Do I need to have stamp duty cash on completion day?
Yes. Your solicitor collects it as part of the completion statement and pays it to HMRC within 14 days of completion. It cannot be borrowed separately; it comes from your own funds. See our guide on total buying costs for full completion day cash requirements.
Can first-time buyers still avoid stamp duty?
Yes, if buying at or under £300,000 in England and Northern Ireland. Between £300,001 and £500,000, a reduced rate applies (0% to £300k, 5% on the excess). Above £500,000, standard rates apply in full with no relief. See our dedicated first-time buyer guide for eligibility rules.
