TDS TCS communication for file NIL Declaration.

You should NOT ignore this communication. Even if no TDS/TCS was applicable, the department expects a response.

Not mandatory by law

But highly advisable to file NIL declaration

Do NOT ignore the notice

Your TAN  number is active therefore in my opinion always better to file NIL retrun or Nil declaration even if in any perticular quater no TDS / TCS  deducted . 

Take more opinion as well .
