UK Stamp Duty Calculator Guide 2026: Rates, Relief & How to Save

Updated 22 March 2026 · 12 min read

Buying a property in England or Northern Ireland? You'll almost certainly pay Stamp Duty Land Tax. The amount depends on the purchase price, whether you're a first-time buyer, and whether you already own another property. Get it wrong and you'll budget incorrectly. Get it right and you might save thousands.

This is the complete guide to stamp duty in 2026 — every rate, every threshold, every exemption, with worked examples at real-world price points and the tools to calculate your exact bill in seconds.

Current stamp duty rates (April 2025 onwards)

The rates below have been in effect since 1 April 2025, when the temporary higher thresholds introduced during the pandemic were withdrawn. If you completed before that date, you paid less. If you're buying now, these are the numbers that matter.

Standard residential rates

These rates apply to anyone buying a residential property who isn't a first-time buyer and doesn't already own another property.

Portion of Purchase PriceSDLT Rate
Up to £125,0000%
£125,001 to £250,0002%
£250,001 to £925,0005%
£925,001 to £1,500,00010%
Over £1,500,00012%

These are marginal rates — you don't pay 5% on your entire purchase price. You pay each rate only on the portion that falls within that band. A £400,000 property doesn't cost £20,000 in stamp duty. It costs £10,000.

First-time buyer rates

If neither you nor anyone you're buying with has ever owned a property anywhere in the world, you qualify for first-time buyer relief.

Portion of Purchase PriceSDLT Rate
Up to £300,0000%
£300,001 to £500,0005%

There's a catch: FTB relief only applies to properties costing £500,000 or less. Buy at £500,001 and you lose the relief entirely — you pay standard rates on the whole purchase. That's a cliff edge worth knowing about.

Additional property rates (+3% surcharge)

Buying a second home, holiday let, or buy-to-let investment? You pay an extra 3% on top of every standard band. This surcharge applies to the entire purchase price, not just the portion above each threshold.

Portion of Purchase PriceStandard RateAdditional Rate
Up to £125,0000%3%
£125,001 to £250,0002%5%

£925,001 to £1,500,00010%13%
Over £1,500,00012%15%

On a £350,000 buy-to-let, the surcharge alone adds £10,500 to your stamp duty bill, taking it from £7,500 to £18,000. That's a significant chunk of your investment capital. Use the additional property calculator to see the full breakdown.

Worked example: buying a £350,000 house

Let's walk through the maths for a £350,000 property — the most commonly searched price point in the UK right now.

Standard buyer

First-time buyer

Additional property buyer

The difference between a first-time buyer and an additional property buyer at £350,000 is £15,500. That's not a rounding error — it's a deposit-sized chunk of money.

How stamp duty actually works (the mechanics)

Stamp Duty Land Tax is a transaction tax, not an annual charge. You pay it once, at the point of purchase. Here's the process:

  1. Exchange contracts — you're legally committed to the purchase
  2. Completion — ownership transfers, you get the keys
  3. SDLT return filed — your solicitor submits the return to HMRC within 14 days
  4. Payment made — the tax is paid, usually from funds held by your solicitor
  5. Land Registry — your ownership is registered (this can't happen until SDLT is paid)

You don't need to calculate or pay stamp duty yourself. Your solicitor or conveyancer handles it. But you absolutely need to know how much it costs so you can budget properly — because it comes out of your cash on completion day, on top of your deposit.

Don't forget the other costs

Stamp duty is just one part of the total cost of buying. You also need to budget for solicitor fees, surveys, Land Registry fees, removals and more. Our moving costs calculator adds it all up.

Who is exempt from stamp duty?

Some transactions are completely exempt:

There's a common myth that you can avoid stamp duty by buying at auction or through a limited company. You can't. The tax applies regardless of the purchase method. Companies buying residential property actually pay more — there's an additional 2% surcharge above £500,000.

How to reduce your stamp duty bill (legally)

You can't dodge stamp duty, but there are legitimate ways to reduce it:

1. First-time buyer relief

The most valuable relief available. If you've never owned a property, you save up to £6,250 on properties up to £500,000. This isn't optional — your solicitor applies it automatically if you qualify. But make sure your solicitor knows you're a first-time buyer. If they apply standard rates by mistake, you'll overpay.

2. Negotiate the purchase price

Stamp duty is calculated on the purchase price, so every pound you negotiate off the asking price reduces your tax. On a property hovering just above a threshold — say £260,000 — negotiating down to £250,000 saves you £500 in stamp duty on top of the £10,000 price reduction.

3. Claim back the additional property surcharge

If you buy a new main residence before selling your old one, you'll pay the 3% surcharge upfront. But if you sell your previous main home within 36 months of buying the new one, you can claim a refund of the surcharge from HMRC. This is worth up to tens of thousands of pounds — don't let your solicitor forget to file the refund claim.

4. Transfer property between spouses

Transfers of property between married couples or civil partners are exempt from SDLT, even if there's a mortgage involved. This can be useful for tax planning — particularly around the additional property surcharge.

5. Shared ownership schemes

If you buy through a shared ownership scheme, you only pay stamp duty on the share you purchase, not the full market value. On a £300,000 property where you buy a 50% share, you'd pay stamp duty on £150,000 — which is £500 for a standard buyer or £0 for a first-time buyer.

What changed in April 2025

The government cut stamp duty temporarily in September 2022, raising the nil-rate threshold from £125,000 to £250,000 and the FTB threshold from £300,000 to £425,000. That relief ended on 31 March 2025.

If you bought before April 2025, you paid less. Here's how the thresholds compare:

Before April 2025From April 2025
Standard nil-rate band£250,000£125,000
FTB nil-rate band£425,000£300,000
FTB maximum price£625,000£500,000

The practical impact: a standard buyer purchasing at £300,000 now pays £5,000 instead of £2,500. A first-time buyer at £400,000 now pays £5,000 instead of £0. Read our full breakdown of the April 2025 changes.

Scotland and Wales have different systems

SDLT only applies in England and Northern Ireland. If you're buying in Scotland, you pay Land and Buildings Transaction Tax (LBTT). In Wales, you pay Land Transaction Tax (LTT). Both have different rates, different thresholds, and different relief for first-time buyers.

Scotland's LBTT has a nil-rate band of £145,000 for standard buyers and £175,000 for first-time buyers. Wales's LTT has a nil-rate band of £225,000 with no separate FTB relief. We cover these separately — this guide focuses on English and Northern Irish SDLT.

Stamp duty for buy-to-let investors

The 3% additional property surcharge makes buy-to-let significantly more expensive than buying a home to live in. On a £500,000 investment property, you'll pay £30,000 in stamp duty — double the £15,000 a homeowner would pay.

This is on top of other tax changes that have made landlording less profitable: the restriction of mortgage interest relief to basic rate, the reduction of the capital gains tax annual exemption, and higher CGT rates on property disposals.

Common stamp duty questions

How much is stamp duty on a £300,000 house in 2026?

A standard buyer pays £5,000. A first-time buyer pays £0 (the entire amount falls within the £300,000 FTB nil-rate band). An additional property buyer pays £14,000.

Do first-time buyers pay stamp duty in 2026?

Not on properties up to £300,000. Between £300,001 and £500,000, you pay 5% only on the portion above £300,000. Above £500,000, FTB relief doesn't apply and you pay standard rates.

What is the additional property surcharge?

An extra 3% on top of standard rates, charged on every band. It applies when you buy a second home, holiday let, or buy-to-let if you already own another property. On a £350,000 purchase, it adds £10,500.

When do I need to pay stamp duty?

Within 14 days of completion. Your solicitor handles the SDLT return and payment. Miss the deadline and HMRC charges interest plus potential penalties.

Can I avoid stamp duty legally?

You can't avoid it on a qualifying purchase, but FTB relief, spouse transfers, buying below the nil-rate threshold, and shared ownership schemes can all reduce or eliminate your bill.

Is stamp duty different in Scotland and Wales?

Yes. Scotland uses LBTT with different rates and a £145,000 nil-rate band. Wales uses LTT with a £225,000 nil-rate band and no FTB relief. This guide covers England and Northern Ireland SDLT only.

The bottom line

Stamp duty is one of the biggest upfront costs when buying a property, and it's not negotiable — HMRC takes what's owed. But knowing exactly how much you'll pay, and whether you qualify for any relief, means you can budget accurately and avoid nasty surprises on completion day.

The single most important thing you can do is run the numbers before you start viewing properties. If your budget is £350,000, you need £7,500 for stamp duty (or £2,500 as a first-time buyer) on top of your deposit, solicitor fees, and other costs. That money needs to be in your bank account on completion day.
