We are using HDFC for corporate NPS. Here’s the process which we follow:
1. Registered our company as a corporate with NPS.
2. Opened NPS accounts for the employees( who opted for it) as a corporate subscriber.
3. For employees who already have NPS account can be converted to corporate subscriber from individual subscriber.
4. Upload monthly contribution file on HDFC NPS portal.
5. Remit the fund to HDFC NPS Account.
6. HDFC NPS team will further deposit amount to the employees individual NPS accounts.
No need to file any return or challan. Upload the contribution file, make payment and share the transaction reference number with HDFC NPS team.
I think the process may be slightly different based on the fund management company you have selected.
