Tax when working Overseas and resident of India .

Hi Guys ,

I am working for a MNC in Gurgoan and a resident of India.

I went to Canada on 9th May 2010 and returned back to India on 7th June 2010 and then again i went
back to Canada along with my wife on 9th Sep 2010 and returned back on 27th may 2011.

I was getting my indian salary (as i was an indian employee only) and was getting per diems of 'X' dollars to maintain myself in host location .

I didn't spend my complete per diems and have saved some amount which was converted to INR and deposited to my salary account by my employer .

Would i be taxed for this ?

I have received my form 16 from my employer and i don't see anything related to my per diems in form 16 .

Currently I m taxed on my indian income (Indian salary).

Would you know , how this works etc ?

Thanks
