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。
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:
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.
Through the Streamlined procedure, you are not required to file all historical years without limit. The IRS only requires the following:
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:
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。
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:
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:
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.
To prevent offshore tax evasion, the U.S. government requires taxpayers to honestly disclose all foreign accounts. This typically involves two forms:
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.
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:
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:
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。
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%)!
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:
If you invest in U.S. stocks through a Taiwan brokerage and have filed a W-8BEN form, here are the key tax points:
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.
Capital gains earned by Taiwanese investors from buying and selling U.S. stocks are completely exempt from U.S. tax (0%)!
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 Item | Taiwan 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) |
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:
信託能存續多久,決定了財富能傳承幾代:
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.
How long a trust can survive determines how many generations it can serve:
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。
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.
