While your employer should be able to provide all ITR documents for the organization, it is not required for an individual.
If you are paying taxes in India, Form -16 as a proof of tax is good enough as mentioned in the visitor-documents pages.
P.S. My husband got his H1-B recently and we submitted a copy of the last year's Form 16 only. ITR-V documents were not asked from us.
