Tds on bill of material with labour

Hi,

pls help me how to book a bill of material with labour charging Vat @ 8% & then service tax @ 4.94% & on what amount should I deduct TDS

But Laxman,

It happens normally when bill components include tax (sales tax & service tax) separately, but what in case of charging VAT 8% on bill value & further 4.94% ser tax on the same bill value ie total of 12.94%
