关于

美国国税局 (IRS) 表格

Form 8879-C 是美国用于报告收入、申请扣除和抵免、计算纳税义务以及履行其他税务相关义务的官方纳税表格之一。美国国税局是负责管理和执行美国国内税收法的联邦机构。

以下是国税局表格的一些示例：

1040表：这是大多数纳税人使用的主要个人所得税申报表。它用于报告各种类型的收入、要求扣除和抵免、计算纳税义务以及确定纳税人是否欠附加税或有权获得退税。

表格 1099：表格 1099 有不同的变体，例如 1099-MISC，1099-INT，1099-DIV等。这些表格用于报告个人或企业从就业以外的各种来源（例如自营职业）获得的收入收入、利息收入、股息收入和租金收入。

W-2表格：雇主使用此表格报告支付给雇员的工资和税款扣留他们的工资。员工使用 W-2 表上的信息来完成个人纳税申报表。

表格 941：雇主使用此表格为其雇员申报就业税，包括联邦所得税预扣税、社会保障税和医疗保险税。

表格 1065：合伙企业使用此表格报告其收入、扣除额和纳税义务。合伙企业本身不缴纳所得税；相反，合伙人在个人纳税申报表上报告其在合伙收入中的份额。

1120表：这是C类公司用来报告其收入的企业所得税申报表，扣除额和纳税义务。

表格 990：该表格由免税组织（例如非营利组织和慈善机构）使用，以报告他们的财务信息、活动以及税法遵守情况。

表格 8862：此表格供之前申请过所得税抵免 (EITC) 的纳税人使用但之前被拒绝了，现在想再次申请。

这些只是 IRS 为履行各种税务相关义务而存在的众多表格中的几个例子。个人或企业所需的具体表格取决于其独特的情况、收入来源和扣除额。建议查阅国税局官方网站 (www.irs.gov) 或寻求专业税务建议，以获得有关特定国税局的准确和最新信息与您的税务情况相关的表格。
