Hello Sir,
As per my understanding, your services fall under the category of intermediary services, place of provision of services will be place of service provider (I.e. India)
Definition of intermediary is contained under section 2 (13) of Integrated Goods and Service Tax Act, 2017 and the same is reproduced here under for ready reference ;
“intermediary means a broker, an agent or any other person, by whatever name called, who arranges or facilitates the supply of goods or services or both, or securities, between two or more persons, but does not include a person who supplies such goods or services or both or securities on his own account”
-GST registration is mandatory for intermediary services without any threshold limit.
-Intermediary generally charge commission against the services provided by them.
-The commission income so earned is subjected to GST@18% and all the provisions of GST law is applicable accordingly.
-Basically GST is a collection from customer and not from own pocket.It is upto you how to collect it from customer either by increasing the commission amount or charging GST separately on the current commission.
-In case there is no commission for a particular period, you will have to file NIL returns. GST shall have to be paid for the month in which invoice is made OR payment is received- whichever is earlier.
