看了一下IRAS网站上写的

Rental expenses算是Deductions，可以减税

但是点开Rental expenses，下面写着

For an expense to be deductible from rental income derived in Singapore, the expense must be incurred:
a. Solely for the purpose of producing the rental income; AND
b. During the period of tenancy.
下面这些可以算作Rental expenses
Housing loans
Property Tax
Fire Insurance
Repairs

这是不是说只有你房子出租了，有了房租收入才能享受Rental expenses的减税？如果自己的房子不出租，没有rental income, 即便有房屋贷款、Fire Insurance等，也不能享受减税？

还有，如果一个房间出租了，大概要交多少的税？Rental expenses又能享受多少的减税？综合算下来，是不是还要净交税呀？谢谢。
