One of our vendor sent us a low deduction of TDS certificate according to it the limit was 350k. where as we have paid him 360k. now we have got notice from the IT dept asking us to pay the difference of tax on 10k (2%-0.56%). we have no business transactions with this vendor. If we pay the difference of the tax and file revised return this vendor gets form 16A for that amount. Is he under obligation to pay the difference of the amount to us?
