你说的这些都是完全合乎流程的做法。现在lz的情况是没有签合同。口头合同也是合同。而且针对没有合同这件事情，肯定是屋主的责任大，否则屋主要求签，租客没有理由不签的。 你看这个说明，印花税是文档税，我的理解是没有文档就不用付。 https://ask.gov.sg/iras/questions/cln4esmvc001c5v0xtffb2giq Do I need to stamp if I am only renting out a room to a friend or family member? There is no tenancy agreement, just verbal agreement. Stamp Duty is a tax on document (physical or electronic). If there is no physical document but the tenancy arrangement was made via electronic modes such as WhatsApp, email, websites, SMS, stamping is still required, and stamp duty is payable. Otherwise, stamping is not required and Stamp Duty is not payable.
