As an NRI, in order for a bank to credit your account with money sent to you from someone in India, the individual making the payment must first file Forms 15CA and 15CB. Let's get a handle on what these structures look like.
Rent is one common way that non-Indian citizens of India make money off of Indian residents. Let's pretend you have an apartment in India that you've rented out. Forms 15CA and 15CB must be submitted by the renter when rent is paid.
If the transaction is taxable in India, the remitter is required to collect TDS and report it on Form 15CA when sending a payment to a non-resident Indian (NRI) under section 195 of the Indian Income Tax Act. Form 15CB requires the submission of a chartered account certificate in certain circumstances.
