美國稅表中的 Form 1116（Foreign Tax Credit） 是一份讓納稅人能夠 申請外國稅額抵免（Foreign Tax Credit, FTC） 的重要表格。當美國納稅人在海外賺取所得並繳納了該國的所得稅時，為了避免雙重課稅，美國國稅局（IRS）允許納稅人使用 Form 1116 來抵減在美國本土需要繳納的聯邦所得稅。
一、Form 1116 的用途
根據美國稅法，美國公民與稅務居民需對其全球收入納稅，這代表即使收入來源在海外，也需向 IRS 申報。然而，如果該筆海外所得已在當地課稅，納稅人便可能有資格申請 外國稅額抵免，藉此避免對同一筆收入被「雙重課稅」。Form 1116 就是用來計算這項抵免金額的主要工具。
二、誰需要填寫 Form 1116？
大部分在海外有收入並已繳納外國所得稅的美國個人或居民外國人，都需要填寫此表。常見情況如下：
- 在海外投資股利、利息、租金或資本利得
- 在海外有工作或經營事業收入
- 有房地產出租所得來自外國
- 收到外國公司發放的股息或其他分紅
- 居住在台灣、香港等地的美籍人士，且有繳納當地稅款
注意：若一年內支付的外國稅不超過 300 美元（單身）或 600 美元（夫妻聯合申報），且符合其他條件，可以選擇不填 Form 1116，直接在主表 Form 1040 上列報外國稅額抵免。
三.抵免與扣除的選擇權
納稅人可在 抵免（Credit） 和 列為扣除（Deduction） 之間擇一：
- 抵免：直接減少應繳稅額，通常稅務上較有利
- 扣除：作為列舉扣除項目的一部分，但僅限於選擇 itemized deduction 的情況
美國註冊會計師 羅霞 提醒您，抵免和列為扣除一經選擇，原則上當年不得更改。Form 1116 是一項協助美國納稅人抵免海外所得稅的工具。雖然填寫上頗為複雜，但透過正確分類海外收入、精準計算稅額與合理分配抵免比例，可以有效減少整體稅負。
對於在台灣或其他國家居住、有海外投資或收入來源的美籍人士來說，理解並善用 Form 1116 是稅務規劃中不可或缺的一環。如稅務情況複雜，建議請教有經驗的美國稅務顧問或 CPA 協助申報。

Form 1116 (Foreign Tax Credit) is an important document in the U.S. tax system that allows taxpayers to claim a Foreign Tax Credit (FTC). When a U.S. taxpayer earns income abroad and pays foreign income taxes, the IRS allows the use of Form 1116 to reduce their U.S. federal income tax liability, in order to avoid double taxation.
1. Purpose of Form 1116
Under U.S. tax law, U.S. citizens and tax residents are taxed on their worldwide income. This means that even income earned abroad must be reported to the IRS. However, if that foreign income has already been taxed in the country where it was earned, the taxpayer may be eligible for a Foreign Tax Credit to avoid being taxed twice on the same income. Form 1116 is the primary tool used to calculate this credit.
2. Who Needs to File Form 1116?
Most U.S. persons or resident aliens who have foreign income and have paid foreign income taxes will need to complete this form. Common situations include:
- Earning dividends, interest, rental income, or capital gains from foreign investments
- Earning wages or business income from working or operating a business abroad
- Receiving rental income from foreign real estate
- Receiving dividends or other distributions from foreign corporations
- U.S. citizens living in places like Taiwan or Hong Kong who pay local income taxes
Note: If the total amount of foreign taxes paid during the year does not exceed $300 for single filers or $600 for joint filers, and other conditions are met, taxpayers may opt not to file Form 1116 and instead report the foreign tax credit directly on Form 1040.
3. Credit vs. Deduction: A Taxpayer's Choice
Taxpayers can choose between claiming a credit or taking a deduction for foreign taxes paid:
- Credit: Directly reduces the amount of tax owed and is generally more advantageous
- Deduction: Can only be used if the taxpayer chooses to itemize deductions, and reduces taxable income rather than the tax itself
USCPA Luo Xia reminds taxpayers that once a choice between credit and deduction is made, it generally cannot be changed for that tax year. Though Form 1116 can be complex to complete, properly classifying foreign income, accurately calculating taxes, and reasonably allocating the credit can significantly reduce overall tax liability.
For U.S. citizens living in Taiwan or other countries, or for those with foreign investments or income sources, understanding and using Form 1116 is an essential part of effective tax planning. If your tax situation is complex, it is strongly recommended to consult with an experienced U.S. tax advisor or CPA.
