您好，稅負(fù)率=當(dāng)期應(yīng)納增值稅/當(dāng)期應(yīng)稅銷售收入 
當(dāng)期應(yīng)納增值稅=當(dāng)期銷項(xiàng)稅額-實(shí)際抵扣進(jìn)項(xiàng)稅額 
實(shí)際抵扣進(jìn)項(xiàng)稅額=期初留抵進(jìn)項(xiàng)稅額+本期進(jìn)項(xiàng)稅額-進(jìn)項(xiàng)轉(zhuǎn)出-出口退稅-期末留抵進(jìn)項(xiàng)稅額 
注1：對實(shí)行"免抵退"的生產(chǎn)企業(yè)而言,應(yīng)納增值稅包括了出口抵減內(nèi)銷產(chǎn)品應(yīng)納稅額 
注2：通常情況下,當(dāng)期應(yīng)納增值稅=應(yīng)納增值稅明細(xì)賬"轉(zhuǎn)出未交增值稅"累計(jì)數(shù)+"出口抵減內(nèi)銷產(chǎn)品應(yīng)納稅額"累計(jì)數(shù)
