Dear aspirant,

You need to submit your recent income certificate if your previously made income certificate validity is over. Generally income certificate has a validity of 6 months.

In case of EWS certificate , the validity is one year. So, that won't create any problem if it is within the date of validity.

EWS certificate is made by those whose family income is less than 8L per annum , who does not own more than 5 acres of land, who does not more than 1000 sqft of flat.

So, I would recommend you to check the validity of both the certificates and work accordingly. If both the certificates comes under validity period then its allright.
