Hi Candidate,

Hope that you are doing well in these tough times!! Income certificate is the document which shows your annual family income per annum and is mainly used for getting Financial Benifits such as Tax Relaxment, Educational Allowance and some other purposes as well.

If you want to make your income certificate with necessary beneficiaries for two siblings, it is not necessary to do two different documents with different beneficiaries since both of you have the same guardian, so you can get it done easily.

Hope that you have got your answer!!

Have a Good Day.
