Hi aspirant,
There are a number of scholarships that you can apply for without having or needing an income certificate. However, there is not a single website where you can access all the scholarships that does not need an income certificate. Many of the government scholarships that are provided for the minority communities does not need an income certificate. Similarly, scholarships that are provided for girl students or research scholars does not need the backing of an income certificate as far as you meet the other needs.
