In reply to a grievance, income tax department has said to make application to Pr. CIT. ( Delhi)
my question is that how can one make application to Pr. Cit ?
is there any option of making application online to Pr. Cit ?
The amount for which assesse seeks application is just Rs. 1200.
is there any procedure online or we have to make application by post???
