Being a proprietorship firm , we are to pay Rs.1 lakh as a contribution to a medical seminar/ held last year .
Is there any need to deduct any form of tax ( service tax /income tax etc, ) prior to paying to the organisers. The conference has no regstartion under any tax authority. I am told that some companies have deducted a part of the committed funds and depositedwith Govt .
Please eductae me.
