Extra stamp duty payable on investment properties and second homes

On April 1 2016, the government introduced higher stamp duty rates for people purchasing additional residential properties. This included most investment properties and second homes.

Property price threshold Standard SDLT rate Buy to Let SDLT rate*
£0 - £125,000 0% 3%
£125,000 - £250,000 2% 5%
£250,000 - £925,000 5% 8%
£925,000 - £1.5 million 10% 13%
£1.5 million or more 12% 15%

* Caravans, houseboats, mobile homes and residential properties bought for less than £40,000 are exempt.

Find out whether the higher rate applies to you

The higher rate of stamp duty applies to most buy-to-let transactions, but some may be exempt. Here is a quick guide to when the rules will apply:

  1. If you own two or more properties at the end of the day of the transaction, unless
  2. The property you bought replaced your main home, and
  3. You are selling your old home.

Claiming a refund

If you do not sell your old home on the same day that you buy your new one, the higher rates will apply. You will have 36 months to claim a refund.

If you do not buy a new home on the same day that you sell your old one, you will have 36 months until the higher rates will apply to the onward purchase. (Assuming that they otherwise would.)

Limited companies

Companies and collective investment vehicles (CIVs) always pay the higher rates, even if they do not own any other properties.
