It is mandatory (w.e.f. June 1, 2003) for corporate deductors to furnish their TDS returns in electronic form (e-TDS return). From F.Y. 2004-2005 onwards furnishing TDS returns in electronic form is also mandatory for government deductors in addition to corporate deductors. Deductors (other than government and corporates) may file TDS return in electronic or physical form. National Securities Depository Ltd. (NSDL) as the e- TDS Intermediary (appointed by ITD) receives, on behalf of ITD, the e-TDS returns from the deductors.
