你好 自2019年4月1日至2021年12月31日（現(xiàn)在有延期），允許生產(chǎn)、生活性服務(wù)業(yè)納稅人按照當(dāng)期可抵扣進(jìn)項(xiàng)稅額加計(jì)10%抵減應(yīng)納稅額。納稅人應(yīng)按照當(dāng)期可抵扣進(jìn)項(xiàng)稅額的10%計(jì)提當(dāng)期加計(jì)抵減額。按照現(xiàn)行規(guī)定不得從銷(xiāo)項(xiàng)稅額中抵扣的進(jìn)項(xiàng)稅額，不得計(jì)提加計(jì)抵減額；已計(jì)提加計(jì)抵減額的進(jìn)項(xiàng)稅額，按規(guī)定作進(jìn)項(xiàng)稅額轉(zhuǎn)出的，應(yīng)在進(jìn)項(xiàng)稅額轉(zhuǎn)出當(dāng)期，相應(yīng)調(diào)減加計(jì)抵減額。計(jì)算公式如下：　　當(dāng)期計(jì)提加計(jì)抵減額=當(dāng)期可抵扣進(jìn)項(xiàng)稅額×10%　　當(dāng)期可抵減加計(jì)抵減額=上期末加計(jì)抵減額余額+當(dāng)期計(jì)提加計(jì)抵減額-當(dāng)期調(diào)減加計(jì)抵減額
