Work contract tax

Kindly some one advice please

1.The Contract Where Labour and Material both are used is called work Contract

2. WCT rate is 4% in Bihar........ when Bill is Certified by the client it is Deducted

3. Contractor Who Use Labour and Material Both for Contract

4. A Client who is certifying any Contractor Bill need to Deduct WCT @ 4%

for example 

BHEL Certifying Bill of NCC for Rs . 1 Crore

Deduction Will be as Follow

TDS @ 2% - 2 00 000

WCT @ 4% - 400 000

Labour Cess @ 1 % - 1 00 000

Net Payble Amount after deduction  - 93 00 000/-

BHEL Transfer Rs - 93 Lakh in NCC Account

Kindly reply on my last question:-

is it deductible on payment basis or due basis?  Suppose If i did't deduct wct on Payment Rs 1000 Should i need to grossing up this figure? Like if need to deduct 4% WCT then i need to Grossing up with Rs. 1042. & deduct Rs. 42 as WCT
