Payment date for Aug-11 is not extended so far. The amount payable is generally known to all registered persons. So, the payment date should not be taken risk off. Paying the tax in due time may save from many problems, so I advise pay the s.tax amount in time i.e. on or before 15 Sept. and later you may e-file the return before 20th.
