Scotland Additional Dwelling Supplement (ADS)

Buying an additional dwelling in Scotland adds the ADS at 8% of the purchase price on top of LBTT — and unlike LBTT it has no nil band, so the 8% starts at the first pound.

These are the rates for a purchase completing on or after 1 April 2025. If yours completed earlier, the rates were different — the main SDLT calculator has a date selector that applies the right bands for 2022–24 and 2024–25.

The rate history

Revenue Scotland sets the ADS rate by order. It is 8% for transactions on or after 5 December 2024, was 6% from 16 December 2022, 4% from 25 January 2019 and 3% before that. Where the contract was entered into on or before 4 December 2024, transitional rules can keep the old rate.

It is charged on the price, not on the LBTT

ADS is 8% of the purchase price, added to the LBTT bill — not 8% of the LBTT. On a £300,000 second home the ADS alone is £24,000, on top of £4,600 of LBTT.

You may be able to claim it back

If you buy a new main home and sell your previous one, the ADS is repayable. For transactions with an effective date on or after 1 April 2024 the previous main residence must have been sold within 36 months before the purchase; before that date the window was 18 months. It is not automatic — Revenue Scotland sets out the conditions and the claim process.
