Entering into partnership.

Yes Pan has to be applied for seperate frim and the previous persons (FCA) experience is counted since the word FCA is valued much in bank audits, CAG etc.,

Can u please guide me about the procedure to be followed for conversion.

Procedural aspects - I am seriosuly not aware but i can say that it normal procedure has to be followed like entering partnership deed, fixing remuneration and appointing managing partner.

Seperate PAN has to be applied and the procedures are normal for it

Feel free to revert back.

And while applying for the PAN what are the documents to be submitted?

I mean we are required to register partnership deed with ICAI ,so while applyin for PAN m i supposed to submit deed or the intimation which institute will be giving me back on being registered.

documents for PAN (Firm)

Partnership deed / bank statement + person signing shall have its id and residentail proof.

yes you need to follow procedures to register with ICAI
