想象一下，您终于敲定了一位重要的海外投资人，或者正准备与国外的伙伴共同拓展美国业务。正当您准备举杯庆祝时，一份关于“Section 1446 预扣税”的 IRS 国税局信函却让您措手不及。
我们通常将 8804 和 8805 表格称为跨国商业的“隐形桥梁”。它们是美国国税局确保当合伙企业盈利时，所有合伙人（包括身在海外的外国合伙人）在利润汇出境外之前，都能依法缴纳应付税款的方式。无论您的合伙人在伦敦、东京还是上海，这两张表格都是您合规经营的“通行证”。
在这份简明指南中，我们将抛弃晦涩的专业术语，为您清晰解析谁需要申报、 预扣税率是多少，
以及如何规避那些让企业主头疼的“意外”罚款。
什么是 8804 和 8805 表格？
您可以将这两个表格看作是 “外国合伙人的缴税收据”。当一家美国合伙企业盈利时，IRS 需要确
保从居住在海外的合伙人那里拿到税款。
- 8804 表格（汇总表）： 它是“总收据”，申报合伙企业代表所有外国合伙人向 IRS 缴纳的税
款总额。 - 8805 表格（个人表）： 它是“个人收据”。每位外国合伙人都会收到一份，证明其名下已缴纳
的税款。他们在申报个人美国税表时，可以用这张表来抵减税款。
谁需要申报？
如果您的合伙企业（或按合伙企业课税的 LLC）拥有有效关联收入 (ECI) —— 简单来说就是在美
经营所得的利润 —— 并且拥有至少一名外国合伙人，您就必须申报。
- 常见误区： 即使您今年没有给外国合伙人实际“打钱”（分红），只要账面上有分给他们的利
润，您就必须代扣代缴税款。
关键截止日期与 2026 年税率
- 截止日期： 2026年3月16日（标准日历年）。
- 税率： * 公司合伙人：21%
- 个人/非公司合伙人：37%
案例分享：北京合伙人的“意外”
假设一家加州的房地产合伙企业有一位身在北京的合伙人。2025 年该企业盈利 20 万美元。即使
企业决定留存现金继续买房，不发放分红，仍需申报 8804/8805 表并为北京合伙人的利润份额缴
税。如果错过截止日期，2026年的罚款约为每张 8805 表每月 330 美元！

Imagine you’ve finally landed that big international investor or expanded your U.S. business with a partner overseas. You’re ready to pop the champagne—until a letter from the IRS arrives asking about “Section 1446 withholding.”
We call Forms 8804 and 8805 the “Global Handshake” forms. They are the IRS’s way of making sure that when a U.S. partnership makes money, everyone—including your foreign partners—pays their fair share before the profits leave the country. Whether your partner is in London, Tokyo, or Shanghai, these forms are your ticket to staying in the clear.
In this quick guide, we’re stripping away the jargon to show you exactly who needs to file, how much to pay, and how to avoid those “accidental” penalties that keep business owners up at night.
What are Forms 8804 and 8805?
Think of these as the “Foreign Partner Receipt.” When a U.S. partnership makes money, the IRS wants to ensure it gets its share of taxes from partners who live outside the U.S.
- Form 8804 (The Summary): This is the “Total Receipt.” It reports the total tax the
partnership is paying to the IRS for all its foreign partners combined. - Form 8805 (The Individual Slip): This is the “Personal Receipt.” Each foreign partner
gets one to show their specific share of the tax paid. They use this to claim a credit when
they file their own U.S. tax return.
Who Needs to File?
If you have a partnership (or an LLC treated as one) that has Effectively Connected Income
(ECI)—basically, profit from doing business in the U.S.—and at least one foreign partner, you
must file.
- The Trap: Even if you didn’t send a check (distribution) to the foreign partner, you still
have to pay tax on the profit allocated to them.
Key Deadlines & 2026 Rates
- The Deadline: March 16, 2026 (Standard calendar year).
- The Rates: * 21% for Corporate Partners.
- 37% for Individual/Non-Corporate Partners.
Example: The “Silent Partner” Surprise
Imagine a California real estate partnership with a partner in Beijing. The partnership made $200,000 in 2025. Even if the partnership keeps the cash to buy more property, they must still file Form 8804/8805 and pay the IRS for the Beijing partner’s share. If they miss the deadline, the penalty is roughly $330 per 8805 form per month!
