Stamp duty proclamation no 110/98 states the following.
It is the Employer who has to pay the stamp duty.
It should be paid before or at the time of signature, and not at the end of probation period.
The amount is 1%(One Percent) of the one month salary.
In addition,
(a) The payment of a stamp duty under Birr 50 shall be effected by affixing stamp of appropriate value to the instrument.
(b) When the stamp duty exceeds Birr 50 or where the type and nature of instrument so requires, the Federal Government Revenues Board may by directive provide that stamp duty be paid by means other than affixing stamp. My suggestion is to better take the agreement before signature to the tax office for a stamp. And
c)Whoever executes or receives an instrument bearing an adhesive stamp shall at the time of execution cancel the same, so that it cannot be used again.
