Stamp Duty on Buy-to-Let: What Landlords Actually Pay

The three layers

Stamp duty on an investment property is built from up to three components. It helps to see them separately before seeing them combined.

Layer one: the standard residential rates. Nothing to £125,000, then 2% to £250,000, 5% to £925,000, 10% to £1.5m and 12% above that. The nil-rate band returned to £125,000 on 1 April 2025 when the temporary £250,000 threshold expired.

Layer two: the higher rate for additional dwellings. If you already own a residential property, or will after the purchase, you pay an extra 5% on every slice, not just the top one. It was raised from 3% to 5% at the Autumn Budget 2024, effective 31 October 2024. It applies to purchases of £40,000 and above.

Layer three: the non-resident surcharge. Non-UK residents pay a further 2% on top of everything else. Residency here is a 183-day presence test over the 12 months before purchase, not a question of nationality. It is refundable if you become UK resident within two years of the purchase.

Combined, an investment purchase by a UK resident looks like this:

A non-resident adds 2 percentage points to each of those, so 7%, 9%, 12%, 17% and 19%.

What it actually costs, at real prices

Rate tables are easy to find. Bills are more useful.

Two of those figures are ours rather than illustrative. Our ten completed client purchases across Leeds postcodes LS9 to LS13 ranged from £78,500 to £115,000 all in. On the purchase price element, that is £3,925 to £5,750 of stamp duty, every one of them at a flat 5% effective rate.

The £203,000 line is the average Leeds terraced property, per ONS. The £450,000 line is roughly what an equivalent London flat costs.

The bit almost nobody points out

Look again at the effective rate column. It is not flat.

A £450,000 London flat costs 3.75 times more than a £120,000 northern terrace. It costs 5.8 times more in stamp duty.

£35,000 against £6,000.

That happens because the 5% surcharge applies from the first pound while the standard rates step up underneath it. A £120,000 purchase sits entirely within the bottom band and pays a flat 5%. A £450,000 purchase climbs through three bands and averages 7.8%.

The practical consequence. Stamp duty on the northern terrace is roughly one year's rent. On the London flat it is closer to two. That is capital which never enters the asset, never earns anything, and is gone the moment you complete.

It is one of the less visible reasons the arithmetic of northern buy-to-let works differently, and it is not an opinion. It is how the bands are constructed. The same pattern shows up in why buying a flat in London is no longer a smart investment, and in the purchase prices behind our client case studies.

Personal name or limited company

The treatment differs in two ways worth knowing.

A company always pays the 5% surcharge, on every band from the first pound, because the main residence exception cannot apply to a company.

And there is a flat 17% rate for companies and certain other bodies buying a single dwelling above £500,000. Reliefs exist where the property is genuinely used in a property rental business, and most buy-to-let companies fall within those and use the standard rates plus the 5% surcharge instead, which is materially cheaper. Corporate ownership also brings the Annual Tax on Enveloped Dwellings into scope in some circumstances.

Which structure suits you is not a stamp duty question in isolation. It turns on your income tax position, how you intend to hold the property, your borrowing, and your long-term plans. It is a conversation for an accountant with your full picture, and it is worth having before you buy rather than after. The running position is set out in tax on rental income: what UK landlords actually pay.

One relief that no longer exists, and one that still does

Multiple Dwellings Relief was abolished on 1 June 2024. It used to reduce the cost of buying several dwellings in one transaction. Portfolio purchases no longer benefit from it, which is a real change if you last bought before mid-2024.

Buying six or more dwellings in a single transaction can still be treated as non-residential, and taxed at the lower commercial rates with no residential surcharge. That is a genuine feature of the rules rather than a workaround, but it is only relevant at a portfolio scale most individual investors are not operating at.

If the property is in Scotland or Wales

Stamp Duty Land Tax applies in England and Northern Ireland only.

Scotland charges Land and Buildings Transaction Tax, with an Additional Dwelling Supplement that rose to 8% in December 2024. There is no non-resident surcharge.

Wales charges Land Transaction Tax, with a higher-rate surcharge of 5% introduced in December 2024. There is also no non-resident surcharge.

We source in Leeds and Sheffield, so SDLT is the relevant regime for everything we buy.

Where stamp duty fits in the decision

Stamp duty is a cost in the deal rather than a reason to avoid property, and unlike most costs it is entirely predictable before you commit.

What matters is that it goes into the model at the start. It is not recoverable, it does not add to the value of the asset, and it is not deductible against your rental income. It is deductible against a future capital gain, and capital gains tax on selling a rental property sets out how that works, but it is a long way off.

Every deal we model includes stamp duty at the correct rate for the client's circumstances, before we present it. A projection that omits it is not a projection, it is a wish. You can see the numbers for yourself in the investment calculator, and the full process in how it works.

The rates are set by legislation and can change at any Budget. Check the current position at gov.uk, or with your solicitor, before you exchange.
