Hi,

Commission to be paid to a sri Lankan co. for its service of facilitating contract in India from another Indian company.

We received contract in India by an Indian Company. Facilitation was done by Srilankan co. We need to pay commission in USD to Srilankan co.

My querry is - Will TDS be attracted in this case, if yes at what %.
