143(1) demand from cpc - remedies

Dear Majumdar,

If there is any mistake in computation or error in TDS consideration etc. you can make rectification request  through online. 

Dear CA Vonod,

Thanks for your response. I knew that. Do you have any clue on the other questions given above.

Regards,

With reference to your query, please note that the appeal can be filed before CIT(Appeals) in paper form. (Not before AO)

If mistake is apparent from the record rectification petition can be filed online or in personal before AO.

 Further, you can also file stay petition before AO, but there should be a sufficient ground like rectification  u/s 154 filed or appeal is filed before CIT(A).
