CIBIL Report by itself does Not Carry your INCOME Records. It is only the Banks which have the data submitted by you in the form of IT Returns of last 3 years and they use it to asses your repaying capacity and ability.
If you are having a CIBIL Report that shows your Income, kindly e-mail the same to me on feedback @ cardbhai dot com and I'll have a look at it.
Thanks.
