At that time of 2007 dept issued C-forms at a time ( like 5, 10 etc.,)without verifying purchase bill and entered in C-form register.
Later dept will strict and limited to issue the c-forms only after verifying the purchase bills.
So the dept stamping date is not a problem. (as per my openion.)
If any douts pls consult any sales tax practioner for more info.
In Gujarat, online C form application was introduced from 1.7.2008. Till then dealers can apply for forms according to their necessity & a book containing either 10 or 25 forms were given in advance to parties, which is utilised by parties to issue to their suppliers. All C forms thus issued are applicable to purchases made up to 30.6.2008.
Hence the C form dated 2007 issued against your bill for April 08 is a valid C form. There is no doubt.

I think u receive the tds as Work Contract Tax and is generally 2% and may vary with state wise. Once u registered with sales tax dept, u got the reg. no and u can file the returns for ur work turnover and u get the refund as such.
PF & ESIC is not refundable and if u not registered then the concerned party ( company) have a liability to deduct the pf & esic on payment of ur labour charges.. (depends on ur agreement and desciption of ur bill)
