Hello Dear,

Income and asset certificates will be valid for a specific period of time. The validity of EWS certificate is decided by the designated authority of the states. However, the validity of EWS certificate is generally one year from the date of the issue. You can check the Department of revenue website of your state to check if the validity of EWS certificate is for one year or for six months. You can renew your certificate the time of document verification.

Good Luck
