Pt return late filing fees of 1000

Dear all,

I file monthly P T returns on Mahavat site but few months back due to utility version ( new upload version) not available on site i couldn't file the retun on time. Now when I am filing the return, I am asked to pay Rs. 1000  for filing late return.

there is no default on my part, why should I pay Rs. 1000/-

Please tell me how to file all PT returns without late filing fees for each month ?

Thanks & regards,

Daxa Manek
