Changes to the additional dwelling supplement (ADS), paid as part of land and buildings transaction tax, would extend the length of time a buyer moving between properties has to sell their original home in order to be able to reclaim the 6% tax surcharge.

The proposals would extend the current time limit from 18 months to 36 months, giving people three years to buy a new property after disposing of a previous main residence. The same rules would apply for those disposing of a previous main residence after purchasing a new main residence.
