The Monetary Authority of Singapore published the Government’s changes to the Seller’s Stamp Duty (SSD) on residential properties, extending the SSD holding period from three to four years and increasing SSD rates by four percentage points for each holding-period tier. The revised SSD applies to all residential properties purchased on and after 4 July 2025, 12.00am, and will not affect HDB owners due to the Minimum Occupation Period for HDB flats. Under the revised schedule, SSD is 16% if a property is sold within one year, 12% if sold after one year but within two years, 8% if sold after two years but within three years, and 4% if sold after three years but within four years, with no SSD beyond four years. The changes revert to the pre-2017 holding period and rates, following a sharp increase in private residential transactions with short holding periods, including sub-sales of units that have not been completed.
