The Singapore government adjusts the seller's stamp duty on residential real estate to curb speculation.

Starting from the 4th day, the lock-in period for seller's stamp duty will be extended from three years to four years, restoring the duration to the level before the last adjustment in 2017. The SSD tax rates for each level of lock-in period will be increased by four percentage points. This means that private residential property owners who sell their units within less than four years of ownership will have to pay higher seller's stamp duty, ranging from 4% to 16%.
