TAX ON PENSION

I donot know how you got the misconception that pension of armed personnel are exempted from Income Tax. Further, to your question whether family pension is taxable and needs to be clubbed, the answer is yes.  "Family Pension" will be taxable under the head, Income from Other Sources. The asseessee will be allowed a deduction of a sum equal to one-third ( 1/3 rd) of such income or rupees fifteen thousand , whichever is less.

there are no exceptions for army pension with regards to Income tax.
 

Family pension received by family of an army man who died on duty or who was reciepient of galantary awards such as 'Veer Chakra" and above is exempt from tax.
