Annual eTDS return

Hi friends,

My Housing Society has deducted the TDS from the Security Services payment as well as payments made towards professional fees and duly deposted the same during the financial year 2008-09, but not yet file any quarterly eTds returns for any quarter, can we file a single annual return for the entire year or should we need to file individual quarterly returns for each quarter, is there any penalty for the late filing of the e-tds return.  What is the due date to file either annual or the delayed quarterly e-tds return.

Thanks.
