Tax Deduction

Hi,

Do the employer need to consider the salary earned by the employee at a foreign country, when the employee is deputed for a short term assignment abroad.

Eg. A software engineer deputed for a project in US for a 3/6 month. Do his India employer need to consider salary earned by the employee for the deputation period in Indian taxation.  Could you please provide some clarity on it, Why or why not?,

Regards,

Benny
