How the higher rates work

If you will own more than one residential property at the end of the day you complete, and you are not replacing your main home, you pay the higher rates of SDLT. These are the normal bands with 5% added to every one of them, including the band that is normally 0%. The surcharge has been 5% since 31 October 2024. Homes you own abroad count, and so does a share of a property.

Worked example: a £300,000 buy-to-let costs £5,000 at standard rates. The 5% surcharge on the whole £300,000 adds £15,000, for a total of £20,000, an effective rate of 6.67%.

The £40,000 floor: the higher rates apply only to purchases of £40,000 or more, and a property worth less than that does not count as one you already own. At £39,999 the bill is £0; at £40,000 it is £2,000.

Married couples and civil partners are treated as one unit: if either of you already owns a home, the higher rates apply even if the other buys alone.

How much is stamp duty on a second home?

Second homes and buy-to-lets pay the standard SDLT bands plus 5% on every band. On a £300,000 property that is £5,000 at standard rates plus £15,000 surcharge, £20,000 in total. On £500,000 it is £40,000.

Do I pay the second home surcharge under £40,000?

No. The higher rates only apply to purchases of £40,000 or more, and a property worth less than £40,000 does not count as a home you already own.

Can I get the stamp duty surcharge back if I sell my old home?

Yes, if the new property replaces your main home. If you sell or give away your previous main residence within 3 years of buying the new one, you can claim back the higher-rates part. Claim within 12 months of the later of the sale and the filing date of the new purchase's SDLT return.

Does the surcharge apply if my spouse already owns a property?

Yes. Married couples and civil partners are treated as buying together, so if either of you will own another residential property after the purchase, the higher rates apply, even if only one of you is named on the new purchase.

Do non-UK residents pay extra stamp duty on a second home?

Yes. Non-UK residents usually pay a further 2% on top of every band, including on top of the 5% surcharge, so a non-resident buying an additional home pays 7% above the standard rates.

What stamp duty does a company pay on a residential property?

Companies pay the 5% surcharge even on their first residential purchase. Above £500,000, certain corporate buyers pay a flat 17% on the whole price unless a relief applies, such as for a property rental business or a property developer.
