随着非法移民问题成为2016年美国总统大选的焦点问题，一项新研究对非法移民对联邦、州和地方税收的贡献进行了更细致的研究。据美国税收和经济政策研究所计算，美国非法移民每年上缴的所得税、销售税以及财产税达116亿美元。

　　For the estimated 10.9 million undocumented immigrants, even if they are not paid on the books, they often still pay income taxes, according to Latin Times. Others, who are not paid in federal and state withholdings, contribute to the government through sales and property taxes.

　　根据拉丁时报报道，即使约1090万的无证移民中的一些人没有通过合法程序获得工资，他们依旧缴税。而其他人虽然不缴纳联邦税或州税，依然以销售税和地税的方式惠及政府。

　　美国非法移民每年缴税超116亿美元 高于富人贡献President Barack Obama's executive actions currently under review by the Supreme Court increase these figures. His measures would regularize the immigration status of around five million undocumented immigrants, a move that is projected to increase tax revenue by $805 million, according to the report.

　　联邦最高法院审议中的欧巴马总统移民行政令，可能还会进一步提高这些税收。报告显示，欧巴马的移民政策将使大约500万无证移民获得合法身份，并预计带来8亿500万元的额外税收。

　　"Data show undocumented immigrants greatly contribute to our nation's economy, not just in labor but also with tax dollars," said Meg Wiehe, ITEP state tax policy director, in a statement. "With immigration policy playing a key role in state and national debates and President Obama's 2014 executive action facing review by the Supreme Court, accurate information about the tax contributions of undocumented immigrants is needed now more than ever."税务及经济政策研究所州税政策主任梅格·维伊在声明中称，“数据显示无证移民不仅以自己的劳动，同时也以税收的形式为美国经济做出贡献。如今，移民政策成为大选辩论焦点，欧巴马总统2014年的行政命令也还在最高法院审议。我们没有任何时候比现在更需要得到无证移民对于税收贡献的准确信息。”

　　The study showed that undocumented immigrants' contributions account for about 8 percent of local income taxes. By comparison, the nation's wealthiest 1 percent pay 5.4 percent of local taxes.

　　研究显示，无证移民缴纳了地方所得税的8%。相比而言，美国前1%的富人只缴纳了其中的5.4%。
