Persons who have ration card to file itr

Yes, because the benefit is only for families having income below poverty line....

There are three types cards, Yellow, orange and white.

The yellow cards are given to families below the poverty line. Orange card is for those having an annual income between Rs.15,000/- and Rs.1 Lakh. Those families having an annual income of over Rs.1 lakh are given white cards.

Ration cards are issued based upon the total members in a family, and each category of the ration card determines an individual’s entitlement to certain rationed goods.

Individuals with higher earning capacity (as fixed by the respective state Govt) cannot obtain rations at a subsidised cost.

Better you visit your concerned ration shop and confirm your benefits
