僅知本月繳納增值稅 50 萬，無法算出軟件部分退稅額。 軟件產(chǎn)品增值稅即征即退稅額 = 當(dāng)期軟件產(chǎn)品增值稅應(yīng)納稅額 - 當(dāng)期軟件產(chǎn)品銷售額 ×3%，其中當(dāng)期軟件產(chǎn)品增值稅應(yīng)納稅額 = 當(dāng)期軟件產(chǎn)品銷項(xiàng)稅額 - 當(dāng)期軟件產(chǎn)品可抵扣進(jìn)項(xiàng)稅額，當(dāng)期軟件產(chǎn)品銷項(xiàng)稅額 = 當(dāng)期軟件產(chǎn)品銷售額 ×13%。 嵌入式軟件產(chǎn)品增值稅即征即退稅額 = 當(dāng)期嵌入式軟件產(chǎn)品增值稅應(yīng)納稅額 - 當(dāng)期嵌入式軟件產(chǎn)品銷售額 ×3%，當(dāng)期嵌入式軟件產(chǎn)品增值稅應(yīng)納稅額 = 當(dāng)期嵌入式軟件產(chǎn)品銷項(xiàng)稅額 - 當(dāng)期嵌入式軟件產(chǎn)品可抵扣進(jìn)項(xiàng)稅額，當(dāng)期嵌入式軟件產(chǎn)品銷項(xiàng)稅額 = 當(dāng)期嵌入式軟件產(chǎn)品銷售額 ×13%，當(dāng)期嵌入式軟件產(chǎn)品銷售額 = 當(dāng)期嵌入式軟件產(chǎn)品與計(jì)算機(jī)硬件、機(jī)器設(shè)備銷售額合計(jì) - 當(dāng)期計(jì)算機(jī)硬件、機(jī)器設(shè)備銷售額。 所以，要計(jì)算軟件部分退稅額，還需知道軟件產(chǎn)品的銷售額、進(jìn)項(xiàng)稅額等具體信息。
