Due to some obvious mistake in form 24 and 26 (TDS returns) filed by assessee company two yrs back (AY 2008-09), complete details in for 26AS of various deductees are not being shown correctly. As a result, the deductees are unable to get their refunds. Now the assessee company (i.e., deductor) wants to make corrections in TDS returns filed by them. How to make corrections - whether complete return will be uploaded again after carrying out corrections or only few entries that were mistaken will be uploaded. How ?
