Service tax payment in royalty on ipr

Dear all,

My company has been earning royalty by franchising its trade mark since 2004. My company in the year 2010 got itself registered with the service tax authority but did not pay any tax even after that.

Now if we wish to pay our service tax & regularise our affairs then how much exposure & penalties are we bound to pay ? Is there any way to compound our said default ?

Kindly advice, as to how should we move ahead in the said regard. Do know, that we are most inclined to regularise our affairs, so how should go forward with the same.

Regards,

Sagnik Sanyal
