Suggestions ????

first of all you pls get registered as vat dealer, then only you can get all the vat credit which you have paid to the registered dealers. And since your turnover has crossed 50 lakh you should get registered. When you will be registered then you will have to raise invoice by charging vat and you can get the vat credit paid to the creditors. 

sir plz read full article ............Because the company already mentioned in the contract that we would not liable to pay any tax.........

plz give me advice what i do ?

Mr Gaurav If you have crossed your turnover 50 lacs and you sell your product then you must register under cst and vat act. And regarding contract with your dealer/vendor which says they wouldnt pay any tax to you is not required  because you can not charge vat /cst unless your are a registrered dealer. And those who are registered will invoice you including vat/cst as the case may be. 

So my suggestion for you is that to register yourselve

1- if you cross your sales over and above prescribed by law to get registered ie. 5 lacs and you have sales crossing 50 lacs

2- to avail the benefit of input vat which you have paid to the venders who registered from whom you have made purchases 

sir,but vat on purchased bill........which is already paid by me .......how to take benefit of those tax

when you get registered you can get the credit of the tax paid on purchases.

1- you you sell in your state you can reduce your input vat already paid agaist your vat liability on sales invoices.

2- if you are selling in ither states then also you will get the benefit.

if your input tax is greater than vat liability at the year end you will be eligible for vat refund.
