Note: For foreigners on EP, once you've moved in, you'll need to update your residential address on your Employment Pass. This informs several government agencies about your new residential address, so they know where to send official communications. This includes the Inland Revenue Authority of Singapore (IRAS), which will send your tax forms to the residential address indicated on your EP.
