Hello Aspirant,

Yes for EWS certificate or even for any other reservation/income certificate, total annual income of whole family from all sources is considered not of individual. So if your father's annual income is Rs. 1 Lakh and Rs. 3.4 Lakhs is of your mother then your total family income will be Rs. 4.4 Lakhs from all sources if there is no other earning member and the same income would be considered for issuing of EWS certificate. Also note that there are some other criterion as well for EWS certificate which you should check with your state's criterion because there might be some differences in eligibility criteria for EWS certificate from state to state.

I hope this information helps you.

Good Luck!!
