Hey student,

Income certificate is a government document that serves as evidence of one's income that is earned from various sources. The certificate discloses, an individual or a family's income details.

The answer to your question -

Yes, it is obvious that once or when you are renewing your income certificate the previous one is obviously expired hence, we can say the old income certificate is not canceled but not valid after renewal.

All the best student,

Hope this helps you.
