Buy to let stamp duty calculator

Property Information


Apply for a buy to let mortgage

Most landlords need to pay extra stamp duty land tax (SDLT) on buy-to-let property acquisitions. Use our stamp duty calculator to find out how much you need to pay.

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 includes most investment properties and second homes.

If you are one of the majority of landlords whose transaction this affects, you will need to factor in the extra cost.

Property price threshold Old lower SDLT rate New higher 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.

Use our stamp duty calculator to find out how much you need to pay

Input your property’s purchase price and hit ‘calculate’. Our buy-to-let stamp duty calculator will tell you:

  • How much tax is payable under the higher rates
  • How much tax is payable under the lower rates
  • How much extra tax you have to pay

This will help you determine for how much more you will need to budget than under the old system.

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.

Conversely, 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.
