Do we need to inform ICA when we are new owner of a HDB flat?

When you become a new owner of an HDB flat, you do not need to inform the Immigration & Checkpoints Authority (ICA) specifically for the change in ownership of the property. However, if the change in ownership results in a change of your residential address, you are required to update your address with ICA within 28 days of moving into the new residence. This can be done through ICA's e-Service portal using your SingPass.

In the context of HDB, the primary notifications and processes involve dealing directly with HDB for the change in flat ownership, which includes attending an appointment at the managing HDB Branch and completing the necessary paperwork and payments.
