Capital gain tax for nri

while computing the taxable income of NRI from LTCG, as per section 115D of the I-T Act, the NRI is not eligible for indexed Cost of acquisition.  hence the cost as was incurred wud be deducted from the sale consideration.  given below is teh calculation of LTCG & the related interst liability u/s 234B & 234C:

it is assuemd that the taxable income would be determined in the month of Jul12 in the A.Y.and the return wud be filed in the same month.  hence intereset u/s234b is being calculated accordingly.  If the taxable income is beind determined beyong Jul12 then the interest liability u/s 234B wud increase accordingly.

thank u very much
