Dividends are credited to the NRE or NRO bank account linked to the Zerodha account. To check the bank account linked with Zerodha,log in to console.zerodha.com/account/bank , or check the CMR copy, see What is a CMR copy and where can I get it?

The dividend is credited by the Registrar and Transfer Agents (RTA). A cheque will be sent to the registered address if the RTA cannot credit the dividends directly to the NRE account. Dividends are subject to applicable taxes before being credited to the bank account. TDS is deducted at a 20% rate for a non-resident shareholder with an additional surcharge and cess.
