See as per the rules, the annual family income must be less than Rs. 8 lacs for the EWS certificate. SO if you have married in January 2022, then you have to include the net increase in your family income in the annual income of the family for the year 2021-22. Now in general, if including the salary of the whole year don't harm the eligibility of the EWS then you can surely mention it, it won't matter. But if it does matter your eligibility, then you can visit the SDO/DM/BDO office & discuss it with the officials, they will guide you out regarding the procedure, as there is no official mentions available regarding such case. So it would be better to be sure about it, if the whole year financial income affects your EWS criteria.

I hope this answer provides you some insight to your problem. Wish you a great eve!
