Income taxation & other formalities for oci

Hi,

I currently live & work in the UK and applying for UK citizenship and then OCI. My question is, if I come back to India after taking UK Passport and OCI what will be the situation in India.

I am told on OCI, I can work in India for any private firm but what I do not know is how the salary or tax things will work? I don't think I'll be allowed to open a resident bank account?

Can anybody help or advise.

Many Thanks in advance!!!
