The 'C' form should be issued quarterly only. There are 4
quarters i.e Apr-Jun, Jul-Sep, Oct-dec, Jan-mar. For example
if we purchase in the month of Apr'12 we shall apply 'C'
form after completing that quarter i.e in July through
online we can apply. After 4days we shall receive 'C' forms
then we can issue to the party. In A.P. any time we can
submit but in out station it is not possible.
