Officials from the Czech Republic and Sri Lanka began negotiations for an income tax treaty on 25 April 2017. Any resulting treaty will be the first of its kind directly between the two countries, and will need to be finalized, signed and ratified before entering into force. Once in force and effective, the new treaty will replace the 1978 tax treaty between Sri Lanka and the former Czechoslovakia, which continues to apply in respect of the Czech Republic and Sri Lanka.
