無打厘印, 是否違法?

租約沒打厘印是沒有犯法，但若然收租但沒有如實報稅，即屬違法。所以依你所講，只要你有報稅，而報既稅沒有隱瞞，都沒有問題。當然你自己亦需要收好有關每月租單紀錄、租金入帳紀錄以備稅局查核。

至於上述有網友回覆，沒打厘印不屬法律文件則有少許偏差。因為根據合約法，只要雙方在清醒既情況下立的契約已有法律約束力，故此，若然有租務糾紛，法院一樣受理，但處理的時間一定比已打厘印租約長。

租約無打厘印不會否違法
但不可作為法庭有效交件.

If you don't 打厘印, it is still an enforceable contract, but it is not protected by

Landlord and Tenant (Consolidation) Ordinance

See http://www.eaa.org.hk/publications/ch_pub_hk_domestic_tenancy.htm

If a tenancy agreement is not stamped, it is then not a legal document. The renting period, rent to be paid, rights and obligation of the landlord and the tenant maynot be legally binding in case a dispute be put for legal action.
For property tax, you just reported the total rental income, including rates or not, in your porperty tax return for tax purposes. Whether there is a legal binding document is not of IRD's concern. The key issue is on the rental income received. However, a stamped tenancy agreement will give a strong support to the rental income received if IRD is in doubt on it.

無打厘印不違法，反而要報稅！

不打厘印只是不能追租,法庭不受理追租！
