Form c tracking and road permit

Hi All,

I am new to the taxation part of Forms tracking and Road permit. I did search many threads on the same.

I wanted a detailed overview on Form C process. Is it different for each state.

In road permit i got state wise list of permit(VAT) forms also. Do we have to consider both receiving ans issue=ing state combination to get the forms.

Please help me on these doubts. Also let me know if we have any books on this to refer and any good websites.

Thank You.
