Income tax on commutation of pension

the uncommuted pension i.e. the monthly pension will remain as it is i.e. 31265*12

as for the commuted pension i.e. 122099 it will be as follows:

122099 minus the exemption

exemption calculated as follows:

if gratuity received : 1/3 * full commuted value of pension

if no gratuity:1/2 *full value of commuted pension

The gratuity slab not the reference looked after in this case...Should the income amount be of either (i) or (ii)...??

Sir, 

Is 1/3  commutation (receiving gratuity) taxable for LIC Group Super annuation -  (contribution paid entirely by employee only) .   Resigned from Private firm after 10+ years of contribution to the fund.

LIC has deducted 30% tax on my commutation. (say  1 Lac Tax levied  on 3 lacs commuted pension) 

Can I show the entire Commutation [3 Lacs] under ITR-2 > EI Sheet > Other Exempt income.. & claim refund.

Kindly reply as due date is nearing. Thanks.
