In most of the State VAT Acts, the provisions of Tax deducted at source (TDS) are incorporated. The logic behind the TDS (WC) provisions is that the Contractors are not organized in many cases and they do not pay taxes on time , therefore in this provision the contractee / customer deducts the prescribed % of TDS from the Contract Price and pays the same before the prescribed dates, directly, to the respective State Government through the specified challan. The TDS is to be deducted by the specified customers only as notified by the State Governments. Generally, the dealers registered under the State VAT Acts, State and Central Governments, Corporations, Government Undertakings, Co-operative Societies only have to deduct the said TDS (WC) and not by all the Customers. The monetary limit of the turnover is prescribed between Contractor and Contractee for such deduction in the hands of the Customer in most of the VAT Acts.
It is responsibility of the Contractee / Customer to deduct the prescribed % of TDS (As provided in the relevant VAT Act & Rules) and pay the same to the State Government before the prescribed date, otherwise interest / penalty is leviable on such Contractees / Customers.
However, as per the State VAT Act provisions, the Seller (Contractor) is liable to pay VAT, if No TDS is made by the Contractee/Customer. The State Governments have prescribed different VAT Forms under the provision of TDS (WC). In certain States, the Contractee has to obtain TANs (Tax deductible Account Number) and file Annual Returns of TDS under the TDS provisions .
In Maharashtra, under MVAT Act, 4% TDS is applicable (instead of 2%) in the case where the Contractor has not obtained the VAT TIN certificate (URD Contractor).
