Stamp Duty Land Tax: the complete guide

What you'll pay, when you'll pay it, and how to make sure you're not overpaying. Current rates, first-time-buyer relief, second-home surcharge, non-resident surcharge, and how to challenge if a property might be exempt.

General guidance, not a personal recommendation. Lender criteria, insurance terms and costs depend on the product and your circumstances.

Stamp Duty Land Tax (SDLT) is a tax paid by the buyer when purchasing residential property in England and Northern Ireland (Scotland has Land and Buildings Transaction Tax, Wales has Land Transaction Tax). It's due within 14 days of completion and is normally paid by your conveyancer on your behalf from the funds at completion.

Stamp Duty is banded, you only pay each rate on the portion of the purchase price that falls within that band. This page covers the current rates, the reliefs and surcharges, worked examples, and the most common questions we're asked. The examples below assume a residential purchase in England or Northern Ireland by a UK resident for SDLT purposes, with no other reliefs or exemptions. Always confirm the amount due with your conveyancer at the point of purchase.

Standard Stamp Duty rates (main residence)

These standard rates apply when higher rates for additional properties do not apply, for example where the purchase leaves you owning only one residential property or you qualify as replacing your main residence:

  • Up to £125,000, 0%
  • £125,001 to £250,000, 2%
  • £250,001 to £925,000, 5%
  • £925,001 to £1.5m, 10%
  • Above £1.5m, 12%

First-time buyer relief

If every buyer is a first-time buyer and has never owned residential property anywhere in the world, and you are buying your only or main residence:

  • Up to £300,000, 0%
  • £300,001 to £500,000, 5%
  • Above £500,000, no first-time buyer relief available, standard rates apply

Additional property surcharge

If the higher rates for additional properties apply to your second-home or buy-to-let purchase, an additional 5% surcharge applies on top of standard rates on the whole purchase price. So a £300k buy-to-let attracts £300k x 5% = £15,000 in surcharge plus the normal tiered amounts.

Non-UK resident surcharge

If you're not UK-resident for SDLT purposes, an additional 2% surcharge applies on top of everything else. Overseas buyers of a second home therefore pay standard + 5% + 2% = 7% above normal rates.

For the current rules and eligibility conditions, see HMRC residential SDLT rates and HMRC higher rates and refunds guidance.

Worked examples

£350,000 home, first-time buyer

first-time buyer relief applies. 0% on first £300k, 5% on £50k = £2,500.

£350,000 home, replacing main residence

Standard rates. 0% on first £125k, 2% on next £125k (£2,500), 5% on next £100k (£5,000) = £7,500.

£350,000 second home or buy-to-let

Assuming the higher rates apply: standard £7,500 plus 5% surcharge on the whole £350k (£17,500) = £25,000.

£600,000 home, replacing main residence

0% on first £125k, 2% on next £125k (£2,500), 5% on next £350k (£17,500) = £20,000.

£1,200,000 home, replacing main residence

0% on first £125k, 2% on next £125k (£2,500), 5% on next £675k (£33,750), 10% on next £275k (£27,500) = £63,750.

Frequently asked questions

Can I add Stamp Duty to my mortgage?

Not directly, Stamp Duty has to be paid from cash at completion, not borrowed from the lender. But you can structure your deposit to include SDLT as part of the cash you bring to completion, effectively borrowing slightly more on the mortgage to free up cash for tax. Whether this is sensible depends on your overall numbers.

What if I'm buying my first home but my partner has owned property before?

If you're buying jointly and your partner has ever owned residential property anywhere in the world, first-time buyer relief is NOT available, you pay standard rates. One joint buyer's previous ownership removes the whole couple's first-time buyer status. This is one of the most common surprises we see.

Can I claim a refund on the second-home surcharge?

You may be eligible if you paid the higher rates when buying a new main home before selling your previous main residence, then sell or give away the previous main residence within 3 years. Neither you nor your spouse can retain any part of the previous home, and higher rates must no longer apply for another reason. For sales on or after 29 October 2018, claim within 12 months of the later of the previous home sale or the filing date of the SDLT return for the new home. Check the full conditions with HMRC and your conveyancer.

Is mixed-use property (flat above a shop) taxed differently?

A transaction containing both residential and non-residential property can fall under non-residential SDLT rules in England and Northern Ireland. Buying only a residential flat above a shop is not automatically mixed-use. The actual land and property bought, use, rights and statutory rules matter. Obtain specialist tax advice before assuming a lower rate or exemption from additional-property rates.

Do I pay Stamp Duty on a transfer of equity (e.g. adding a spouse to the deeds)?

Potentially, yes, Stamp Duty can apply on transfers of equity where the recipient takes on half the mortgage. The tax is calculated on the mortgage consideration (roughly half the debt), and if that crosses SDLT thresholds, tax is due. Specialist advice before doing the transfer is usually the best approach.

What happens if my property has defects that make it uninhabitable?

A property unsuitable for use as a dwelling (serious defects, derelict property, etc.) may qualify for non-residential SDLT rates instead of residential rates, which can be a substantial saving. This is an active area of SDLT dispute with HMRC; specialist SDLT advice is essential before claiming this treatment.
