Please send a copy of the rental agreement and the extension of the rental agreement by e-mail. An instant stamp service by GovHK (www.gov.hk/etax) Hello, my name is Ivan, can I have a copy of a rental agreement? Just curious, can we not go to the IRB to stamp the renewed lease, but rather to the Commissioner of oaths? Stamp certificates issued by the stamp receipt collector have the same legal status as conventional instrument stamps. Certificate authentication is possible with www.gov.hk/estamping. The calculation is easier here. In the previous example of RM1,700 per month`s rent, the administration fee is RM150. Therefore, for a lease of one year or less, the total amount that must be paid (stamp duty and administrative fees): (RM82 + RM150) = RM232. . . .
