常見問題

01 什麼是 Streamlined 補報程序(Streamlined Filing Compliance Procedures)?

Streamlined 補報程序是美國國稅局(IRS)專門為長年漏報海外收入、海外金融資產的美國納稅義務人(包含美國公民、綠卡持有人及稅務居民),所提供的一種「自首免罰」或「減罰」的寬大補報機制。

這個程序的核心目的,是讓那些「非故意(Non-Willful)」而漏報的稅務人,能夠以最精簡的流程重新回到合規(Compliance)狀態。

核心申報要求

透過 Streamlined 程序補報,您不需要無限制地補齊所有歷史年度,IRS 規定只需要補交以下內容:

  • 3 年的聯邦個人所得稅申報書(Form 1040 或 1040X)。
  • 6 年的海外銀行與金融帳戶報告(FBAR, FinCEN Form 114)。
  • 簽署非故意聲明書(Form 14653 或 14654),詳細說明過去未申報的合理原因。

The Streamlined Filing Compliance Procedure is a voluntary disclosure program offered by the IRS specifically for U.S. taxpayers (including U.S. citizens, green card holders, and tax residents) who have long failed to report foreign income or foreign financial assets. It provides a "reduced-penalty" or "penalty-free" path back into compliance.

The core purpose of this program is to allow taxpayers whose non-compliance was non-willful to return to a compliant state through a streamlined process.

Core Filing Requirements

Through the Streamlined procedure, you are not required to file all historical years without limit. The IRS only requires the following:

  • 3 years of federal individual income tax returns (Form 1040 or 1040X).
  • 6 years of Foreign Bank Account Reports (FBAR, FinCEN Form 114).
  • A signed non-willfulness certification (Form 14653 or 14654), explaining in detail the reasons for prior non-compliance.
02 身為美國納稅人(公民/綠卡/稅務居民),每年例行性申報到底要報什麼?

美國的例行性年度申報(Annual Tax Filing)並不是「一張表報完所有的稅」。它是由個人所得稅表、海外金融資產報告,以及地方州稅共同構成的三大申報體系。

只要您符合美國稅務居民身分,無論您住在美國境內、還是住在台灣,每年都必須依法完成以下這三大重點的盤點與申報:

重點一、個人聯邦所得稅申報(Form 1040)—— 核心稅表

這是每個人都要報的主稅表。美國實行「全球所得課稅(Worldwide Income)」,也就是說,不論錢是在美國、台灣、還是世界任何地方賺的,全部都要併入申報。

  • 常見申報收入:W-2 薪資、美股與台股的股利及資本利得、台灣房屋租金收入、銀行利息、甚至是自由業的接案收入。
  • 搭配的常見附表:
    • Schedule B:利息與股利。
    • Schedule D:股票、房屋等資產的買賣價差(資本利得/損失)。
重點二、海外金融帳戶與資產披露 —— 沒繳稅也要報(不報罰最重!)

美國政府為了防止海外藏錢,規定納稅人必須「誠實申報名下的外國帳戶」。這部分通常包含兩張表:

  1. FBAR(肥爸條款 / FinCEN Form 114):只要您在美國以外國家(如台灣)的所有金融帳戶(存款、證券、有現金解約價值的保單),所有帳戶的「年度最高餘額」加總超過 1 萬美元,就必須向美國財政部獨立申報。
  2. FATCA(肥咖條款 / Form 8938):屬於 Form 1040 的附表。申報門檻比 FBAR 高,申報內容為海外金融資產(包含金融帳戶、有現金解約價值的保單、未上市櫃公司股權等),依照居住地及申報身份門檻有所不同。
重點三、州稅與地方稅申報(State & Local Tax Returns)

除了聯邦稅,如果您在美國境內特定州居住、工作、或在該州有收入(例如在加州有出租房、在紐約州公司領薪水),您通常還需要申報該州的個人所得稅。

The U.S. annual tax filing is not a single form that covers everything. It is made up of three distinct systems: individual income tax returns, foreign financial asset reports, and state & local taxes.

As long as you qualify as a U.S. tax resident — whether you live in the U.S. or in Taiwan — you are required by law to complete the following three key obligations each year:

Part 1: Federal Individual Income Tax (Form 1040) — The Core Return

This is the primary return that every U.S. taxpayer must file. The U.S. operates under worldwide income taxation — meaning all income earned anywhere in the world must be reported.

  • Common income types: W-2 wages, dividends and capital gains from U.S. and Taiwan stocks, Taiwan rental income, bank interest, and freelance income.
  • Common accompanying schedules:
    • Schedule B: Interest and dividends.
    • Schedule D: Capital gains and losses from stocks, real estate, and other assets.
Part 2: Foreign Financial Account & Asset Disclosure — Required Even Without Tax Owed

To prevent offshore tax evasion, the U.S. government requires taxpayers to honestly disclose all foreign accounts. This typically involves two forms:

  1. FBAR (FinCEN Form 114): If the aggregate maximum annual balance of all your financial accounts outside the U.S. (deposits, securities, cash-value insurance policies) exceeds $10,000, you must file separately with the U.S. Treasury.
  2. FATCA (Form 8938): An attachment to Form 1040. Reporting thresholds are higher than FBAR and cover foreign financial assets including bank accounts, cash-value policies, and equity in unlisted companies. Thresholds vary by residency and filing status.
Part 3: State & Local Tax Returns

In addition to federal taxes, if you live, work, or earn income in a specific U.S. state (e.g., rental property in California or a salary from a New York company), you are generally also required to file that state's personal income tax return.

03 台灣人投資美股或是去美國工作,美國稅到底怎麼課?

台灣人在面對美國稅務時,第一步也是最重要的一步,就是釐清自己的「稅務身分」。身分不同,課稅基礎(全球課稅 vs. 僅課美國來源所得)與稅率有著天壤之別。

我們通常將情況分為兩大類:

  1. 人在台灣」的純美股投資人:屬於美國稅法上的非美國稅務居民(Non-Resident Alien, NRA)
  2. 赴美工作」的上班族:只要持有 H-1B、L-1 等工作簽證並通過「實質居住測試(Substantial Presence Test)」,就會轉為美國稅務居民(US Person)
第一部分、人在台灣,單純投資美股(NRA 身分)

如果您只是在台灣複委託或開立美股券商投資,填寫了 W-8BEN 表單,您的稅務重點有以下幾個:

  1. 股利所得(Dividends)—— 30% 預扣稅

    美國公司發放給外國人的股利,會被強制預扣 30% 的稅(因為台灣與美國目前尚無實質租稅協定,無法像日本或中國享受 10% 或 15% 的優惠稅率)。券商發放時會直接扣除,您不需要自行申報。

  2. 資本利得(Capital Gains)—— 0% 免稅

    台灣人買賣美股賺取的「價差(賺到的本金增值)」,美國政府完全不課稅(0%)

第二部分、赴美工作(轉為美國稅務居民 US Person)

一旦您拿工作簽證赴美,並在當年度待滿 31 天,且過去三年依公式計算累積滿 183 天(實質居住測試),您在法律上就變成了「美國稅務居民」,稅務環境將發生劇烈改變:

稅務項目人在台灣投資美股(NRA)赴美工作(US Person)
課稅範圍 僅限美國來源所得(US-Source) 全球收入課稅(Worldwide Income)
包括台灣的薪資、台灣房租、台灣股票獲利
美股買賣價差 0% 免稅 併入個人所得。持股 >1 年為長期資本利得(0%–20%);持股 ≤1 年為短期資本利得(最高 37%)
美股股利 30% 差額直接預扣 依個人總收入稅率課稅(若符合 Qualified Dividend 則為 0%–20%)
海外資產申報 無需申報 若超過門檻,必須強制申報!
台灣銀行帳戶超過 1 萬美元需報 FBAR(肥爸);
海外金融資產超過門檻需報 FATCA(肥咖 / Form 8938)
遺產稅免稅額 僅有 6 萬美元 高達 1,500 萬美元(2026 年最新聯邦免稅額,若未規劃個人名義極難被課到)

For Taiwanese nationals facing U.S. tax obligations, the most critical first step is determining your tax status. The difference is enormous — it determines whether you're taxed on worldwide income or only U.S.-source income.

We generally divide situations into two categories:

  1. Taiwan-based U.S. stock investor: Classified as a Non-Resident Alien (NRA) under U.S. tax law.
  2. Worker relocating to the U.S.: Once holding an H-1B, L-1, or similar work visa and passing the Substantial Presence Test, you become a U.S. Tax Resident (US Person).
Part 1: Taiwan-Based, Investing in U.S. Stocks (NRA Status)

If you invest in U.S. stocks through a Taiwan brokerage and have filed a W-8BEN form, here are the key tax points:

  1. Dividends — 30% Withholding Tax

    Dividends paid by U.S. companies to foreign nationals are subject to a mandatory 30% withholding tax (since Taiwan and the U.S. currently have no substantive tax treaty, Taiwan investors cannot enjoy the reduced 10%–15% rates available to Japanese or Chinese investors). The broker withholds it directly — no self-reporting required.

  2. Capital Gains — 0% Tax

    Capital gains earned by Taiwanese investors from buying and selling U.S. stocks are completely exempt from U.S. tax (0%)!

Part 2: Working in the U.S. (Becoming a U.S. Tax Resident)

Once you work in the U.S. on a work visa, spend at least 31 days in the current year, and meet the 183-day threshold under the Substantial Presence Test over three years, you legally become a U.S. tax resident — and your tax environment changes dramatically:

Tax ItemTaiwan Investor (NRA)U.S.-Based Worker (US Person)
Tax Scope U.S.-Source Income Only Worldwide Income (including Taiwan wages, rental income, and stock gains)
Stock Capital Gains 0% — exempt Included in personal income. Long-term (>1 yr): 0%–20%; Short-term (≤1 yr): up to 37%
Stock Dividends 30% withheld at source Taxed at personal income tax rate (Qualified Dividend rate: 0%–20%)
Foreign Asset Disclosure Not required Mandatory above thresholds. Taiwan accounts >$10,000 require FBAR; foreign financial assets above threshold require FATCA (Form 8938)
Estate Tax Exemption Only $60,000 Up to $15M (2026 federal exemption — nearly impossible to trigger without proper planning)
04 為什麼現在財富規劃首選「美國信託」,而不是開曼、VISTA(BVI)等傳統小島信託?

過去三十年,開曼、BVI 等租稅天堂(Offshore Islands)因其高度保密性與零稅率,成為離岸信託的代名詞。然而,隨著全球反避稅浪潮全面爆發,小島信託的保密神話已經破滅。

現在,高資產家族更傾向將資產放入美國特定州(如內華達州、南達科他州、德拉瓦州)的美國信託。這並非盲目跟風,而是基於隱私法規、法律穩定性、資產控制權以及稅務合規的四大優勢:

優勢一、完美的 CRS 防火牆(最強隱私保護)
  • 小島信託的致命傷:開曼、BVI、百慕達等小島全部都加入了 CRS(共同申報準則)。這意味著,小島信託內的資產資訊、委託人及受益人身分,每年都會被自動交換回受益人的稅務居住地(例如台灣或中國)。在國稅局面前,小島信託幾乎是透明的。
  • 美國信託的防禦力:美國至今「拒絕加入」CRS。美國是用自己的 FATCA(肥咖條款)單向索取全球資料,但並不主動把美國境內信託的非美籍客戶資訊與其他國家自動交換。因此,將資產放在美國信託中,能享有全球目前最高級別的隱私保護。
優勢二、真正強大的司法主權與政治穩定度
  • 小島信託的危機:這些加勒比海小島常面臨歐盟「黑名單/灰名單」的制裁壓力,法規近年被迫頻繁變更(例如增設「經濟實質法」),導致維護成本飆升、架構隨時可能失效。此外,若發生重大地緣政治衝突,小島缺乏足夠的國際地緣政治防禦力。
  • 美國信託的穩定:美國擁有全球最強大的金融與軍事主權。美國特定州(如南達科他州、內華達州)的信託法是由該州憲法級別的法律保障,具有數百年的聯邦司法判例支持。其法律的預期性、穩定性與抵抗外來訴訟的能力,是任何新興小島都無法比擬的。
優勢三、極致的「朝代信託」永續期

信託能存續多久,決定了財富能傳承幾代:

  • 傳統小島:通常有「反永續期條例(Rule Against Perpetuities)」的限制(例如最長 100 年或 150 年),到期信託必須強制解散並分配資產,屆時會觸發大筆稅負。
  • 美國特定州:南達科他州和內華達州早已廢除反永續期限制。在這些州設立的「朝代信託(Dynasty Trust)」可以永久存續(甚至長達 360 年至無限期)。這意味著您的財富可以世世代代鎖在信託架構內,在信託內部永續增值且降低遺產稅的風險。
優勢四、資產控制權的「指示型信託(Directed Trust)」架構
  • VISTA 信託的局限:BVI 雖然開發出 VISTA 信託試圖讓委託人保留旗下公司股權的投票權,但其法規靈活性仍受限於英國普通法體系的框架。
  • 美國指示型信託的彈性:美國開創了現代信託最頂級的「指示型信託」法規。它將受託人(Trustee)的職責「一拆為四」:
    1. 行政受託人:僅負責法規合規與日常行政。
    2. 保護人:信託中權力最大的角色,可以新增移除受益人、指示信託分割、變更受託人等等的權力。
    3. 投資委員會:由您或您指定的專業人士擔任,全權決定信託資產如何投資,信託公司無權干涉。
    4. 分配委員會:決定什麼時候給子女發錢。
    這徹底解決了東方企業家「把資產交給外國信託公司就不安全、不能自己操盤」的終極焦慮。

For the past three decades, Cayman Islands, BVI, and other tax havens served as the go-to jurisdictions for offshore trusts due to their secrecy and zero tax rates. However, as the global anti-tax-avoidance wave has swept the world, the myth of offshore secrecy has collapsed.

High-net-worth families now increasingly favor U.S. trusts in specific states (Nevada, South Dakota, Delaware) — not out of trend-following, but for four compelling advantages: privacy regulations, legal stability, asset control, and tax compliance.

Advantage 1: The Perfect CRS Firewall (Strongest Privacy Protection)
  • The Fatal Flaw of Offshore Islands: Cayman, BVI, Bermuda, and similar jurisdictions have all joined CRS (Common Reporting Standard). This means trust asset information, settlor identities, and beneficiary identities are automatically exchanged with the beneficiaries' home tax authorities (e.g., Taiwan or China) every year. Offshore trusts are essentially transparent to tax authorities.
  • The U.S. Trust Advantage: The U.S. has refused to join CRS. It uses its own FATCA to collect information globally — but does not proactively exchange non-U.S. clients' information held within U.S. trusts with other countries. Assets held in U.S. trusts enjoy the highest level of privacy protection available anywhere in the world.
Advantage 2: Genuine Judicial Sovereignty & Political Stability
  • The Crisis of Offshore Islands: Caribbean jurisdictions constantly face EU blacklist/greylist sanctions, forcing frequent regulatory changes (e.g., new "Economic Substance Laws"), causing compliance costs to surge and structures to become unstable. In a major geopolitical conflict, these small jurisdictions have no meaningful defensive capability.
  • U.S. Trust Stability: The U.S. possesses the world's most powerful financial and military sovereignty. Trust laws in specific states (South Dakota, Nevada) are backed by constitutional-level state laws and centuries of federal judicial precedent. Their legal predictability, stability, and resistance to external litigation are unmatched by any offshore jurisdiction.
Advantage 3: The Ultimate Dynasty Trust Duration

How long a trust can survive determines how many generations it can serve:

  • Traditional Offshore Islands: Typically subject to the "Rule Against Perpetuities" (e.g., maximum 100 or 150 years). When the trust expires, it must be dissolved and assets distributed — triggering substantial tax liability.
  • Specific U.S. States: South Dakota and Nevada have abolished the Rule Against Perpetuities. Dynasty Trusts established in these states can exist permanently (even up to 360 years or indefinitely). Your family's wealth can remain locked within the trust structure for generations, compounding internally while minimizing estate tax risk.
Advantage 4: Asset Control Through the "Directed Trust" Structure
  • The Limitation of VISTA Trusts: While BVI developed the VISTA trust to allow settlors to retain voting rights over company shares, its regulatory flexibility remains constrained by the British common law framework.
  • The Flexibility of U.S. Directed Trusts: The U.S. pioneered the world's most sophisticated "Directed Trust" regulations. It splits the traditional trustee role into four distinct functions:
    1. Administrative Trustee: Responsible only for regulatory compliance and day-to-day administration.
    2. Trust Protector: The most powerful role in the trust — can add or remove beneficiaries, direct trust division, change trustees, and more.
    3. Investment Committee: Staffed by you or your designated professionals, with full authority over how trust assets are invested — the trust company has no right to interfere.
    4. Distribution Committee: Decides when and how distributions are made to beneficiaries.
    This completely resolves the ultimate anxiety of Asian entrepreneurs: "Giving control of my assets to a foreign trust company is unsafe — I can't manage it myself."
05 為什麼要用美國「不可撤銷信託」來傳承美國境內資產?它與可撤銷信託的差異?

如果您的傳承目標僅僅是「避開法院認證(Probate)」,普通的「可撤銷信託」就足夠了;但如果您希望能「規劃減少支付 40% 的美國遺產稅」,或者想「防止資產被未來的債權人、官司或子女離婚配偶分走」,那麼不可撤銷信託(Irrevocable Trust)是唯一的選擇。

它的底層核心邏輯是:「資產所有權的徹底剝離」。當您把美國的房產、美股或現金轉入不可撤銷信託後,您在法律上就不再是這些資產的主人。因為美國不可撤銷信託是一個主體,美國國稅局(IRS)自然無法在您過世時徵收遺產稅,債權人也無法對信託內的資產進行追討。

美國不可撤銷信託的四大核心優勢
  1. 減少稅務風險(Tax Risk Mitigation):資產一經移轉,代表放棄其資產的所有權,將來非美籍設立人過世可以減少美國遺產稅的風險。
  2. 資產防護隔離(Asset Protection):信託設有「禁止揮霍條款(Spendthrift Clause)」。由於受益人對信託沒有直接控制權,當受益人面臨法律官司、債務危機或離婚財產分配時,信託資產能得到完美的法律庇護,債權人無法就信託資產請求返還。
  3. 朝代信託(Dynasty Trust):利用內華達州(Nevada)的法律,信託甚至可以存續數百年,達成傳承的目的。
  4. 避開法院認證(Avoid Probate):設立人過世時,信託依然正常運作,資產無需經過長達數月的法院清算,受益人依然可以獲得信託利益。

If your only estate planning goal is to avoid probate, a standard revocable trust is sufficient. But if you want to reduce exposure to the 40% U.S. estate tax, or protect assets from future creditors, lawsuits, or a child's divorcing spouse, then an Irrevocable Trust is the only option.

Its fundamental core logic is: "Complete Divestiture of Ownership." Once you transfer U.S. real estate, U.S. stocks, or cash into an irrevocable trust, you are no longer the legal owner of those assets. Because a U.S. Irrevocable Trust is a separate legal entity, the IRS cannot impose estate tax at your death, and creditors cannot pursue assets held within it.

Four Core Advantages of a U.S. Irrevocable Trust
  1. Tax Risk Mitigation: Once assets are transferred, ownership is relinquished. Upon the death of a non-U.S. settlor, the risk of U.S. estate tax on those assets is substantially reduced.
  2. Asset Protection: The trust includes a "Spendthrift Clause." Because beneficiaries have no direct control over the trust, when they face lawsuits, debt crises, or divorce proceedings, trust assets are fully shielded by law — creditors cannot seek repayment from trust assets.
  3. Dynasty Trust: Under Nevada law, the trust can exist for hundreds of years, achieving true multi-generational wealth transfer.
  4. Probate Avoidance: Upon the settlor's death, the trust continues to operate normally. Assets do not need to go through months of court liquidation — beneficiaries can continue to receive trust benefits without interruption.
