ABSD when upgrading from HDB to a condo.

Buy the condo before selling your HDB flat and you own two homes for a while. For a Singapore Citizen that means 20% Additional Buyer’s Stamp Duty on the condo. A married couple can get it back, but only if every condition is met.

The remission for married couples

IRAS refunds the ABSD only if all of these are true:

You pay first, then get it back

The ABSD is paid upfront when the condo purchase is stamped. If you declared at purchase that you would sell and claim the refund, IRAS refunds it automatically within about 6 weeks after your HDB sale is stamped. Otherwise, apply within 6 months of the sale. Plan the cash, or a bridging loan, for the months in between.

There is no extension

IRAS states that the 6-month deadline is not extended. Miss it and the 20% stays paid.
