From Justification Report (Intimation Notice): Notice generated on 27-March-2015
Date of Transaction: 19-Nov-13
Date of deposit: 11-Jan-14
Delay in filing: 35 Days
Penalty fee: 7000/-
Interest on Late Payment: 1089/-
....

A few Questions:
Q1. Can I pay Interest and penalty fees through single challan (online) or need to pay separately?
Q2. I understood that since the TDS form (16B) has already been generated (on 11-Jan-14), the late fee can not be recovered now?
If this is true:
Q2a. Can I pay just the interest and not pay the Late fees? If yes, how do I intimate the tax department that I am not paying the late fees?
3. Shall I get a CA to handle this?
 
Any recommendations Please.
