Sales tax returns filing

If sales tax return is filed with mention of pending c-forms ; maharashtra sales tax deptt. immediately issues demand note for sales tax difference . Many large corporate companies do not file their returns in time and hence are unable to issue C- Forms to their vendors . These companies protect themselves by paying meagre penalty of rs.10000 . In the process their vendors are in soup as they do not get C-forms from such large scale companies . For example ; Jayaswal Neco Industries Nagpur are still not able to issue C-Forms for the bills of 2nd quarter of 2014 - 15 as on 20/06/2015 . Jindal Steel & Power Ltd. Raigarh have still not issued C - Forms for my bills of last quarter of 2014-15 yet as on 20/06/2015 .What is the solution for such problems .
