On getting more clarity regarding submission of correction statement of e-tds/e-tcs return more than one time. It is found that there is no need to cancel the earlier statement. Correction statement can be uploaded more than one time without cancellation of earlier uploaded statement.
Now, it is very much clear that the original return can be submitted only one time. It can be cancelled only in one case which is TAN changed. In case you have entered wrong TAN number in original return. You can cancel the same and upload your return in correct TAN number.
To submit correction return more than one time through NSDL software, Still i am not confirm that it can be submitted or not, there may be some chances to submit. But the correction statement more than one time can be submitted through nodal centers.
