Suppose your company is named 'X' and your subcontractor is 'Y' under a contract with company Z. In this scenario, Z is the principal employer, X is the contractor, and Z shall issue Form V only to X, not to Y, as the contract agreement is between Z & X, not Z & Y. X has engaged Y solely for accounting benefits.
Even if you enter into a tripartite agreement among X-Y-Z, whereby Y works under contract in Z company, Z should issue Form V, obtain RC for Y, and release monthly payments to Y, verifying all legal requirements of Y.
Purpose of Entering a Tripartite Agreement
What is the purpose of X entering a tripartite agreement? In the eyes of the law, X lacks a legal entity as Y functions as an independent contractor.
