Taxation between switzerland and india

Dear All,

I work for an indian IT company and has been deputed to switzerland for 2 years. I arrived in switzerland on 02-oct-2011. I need to understand the computation of tax on my total income for current financial year.

Suppose i earn X amount in India and Y amount in Switzerland. on X , i would be paying tax based on indian law and on y would be paying tax based on switzerland laws. Suppose i transfer Z amount out of Y amount to india (via Bank transfer to my salary account in india) now am i supposed to pay  tax on this Z amount based on indian taxation. i have heard some treaties based on double taxation but not sure of them.

Any help would be appreciated.

Thanks,

Vivek
