What is the due date for TDS deposit?

We are a Ltd. comapany. Wehave not deducted any TDS in Financial Year(FY) 2005-06 and 2006-07 so we have also not filed E-TDS for that corresponding Year. Now in FY 2007-08 we have deducted TDS.Now my question is Whether we have to file E-TDS for 2005-06, 2006-07 and 2007-8 FY or only for FY 2007-08.If we have to file E-TDS for 2005-06 and 2006-07 then penalty of Rs.100/- per day will be levied or not.
