Chinese tax residents filling out W-8BEN: put your 18-digit national ID number on line 6a. You can do this even without an SSN or ITIN.
The form itself is only three parts. Most people filling it out for the first time aren't tripped up by the structure โ they're tripped up by a handful of specific lines where the instructions either assume US context that doesn't apply to you, or where the obvious-seeming answer turns out to be wrong. This guide goes through those lines directly.
Are you even filling out the right form?
| Your situation | Correct form |
|---|---|
| Non-US individual, not conducting a US trade or business | W-8BEN |
| Non-US company, partnership, or other entity | W-8BEN-E |
| US citizen, green card holder, or US tax resident (even if living abroad) | W-9 |
| Non-US person whose income is effectively connected to a US trade or business | W-8ECI |
| Foreign intermediary, collecting agent, or foreign flow-through entity | W-8IMY |
| US single-member LLC owned solely by a foreign individual | Under IRS rules, the owner fills W-8BEN in their own name as an individual; entity-level accounts have separate requirements covered elsewhere |
What W-8BEN actually does
The full name is "Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting (Individuals)." You don't submit it to the IRS โ you hand it to whoever is paying you or opening an account for you: the platform, broker, or bank. It does two things: confirms you're not a US person so the payer doesn't withhold and report as they would for a US taxpayer, and lets you claim a treaty-reduced rate when that applies.
Nobody legally requires you to file this proactively. But if a payer asks for it and you don't provide one, they'll either block your account setup or apply the default withholding rules, which you generally don't want.
The three main contexts where you'll be asked for it: payment platforms โ Stripe's help documentation explicitly says it uses W-8 forms to confirm your tax residency, and may ask again when you update your bank account or address even if you've submitted one before. Brokers and banks, when opening accounts, need to confirm you're not a US tax resident before they can handle interest and dividends without US-person treatment. Content platforms and app stores ask for this through their tax information screens when you select individual status.
Line by line
| Line | Field | How to fill it | Common mistake |
|---|---|---|---|
| 1 | Name of beneficial owner | Use your pinyin name, consistent with your platform account and official documents. Passports list surname first; many US-format forms expect given name first โ follow whatever the field labels say | Pinyin inconsistent with account name, or surname/given name reversed |
| 2 | Country of citizenship | Your country of citizenship, e.g. China. Dual citizens should list the country where they hold citizenship and are a tax resident | Listing country of residence instead of citizenship |
| 3 | Permanent residence address | Your actual residential address in your country of tax residence, in English, down to the country name โ e.g. Room 1203, Building 5, XX Road, XX District, Shanghai 200000, China | Filling in a P.O. box, forwarding address, or your US LLC's registered agent address |
| 4 | Mailing address | Leave blank if same as line 3; only fill if different | Putting China on line 3 and a US address on line 4 โ platforms will flag you as a possible US tax resident |
| 5 | US taxpayer identification number | Leave blank if you have no SSN or ITIN | Entering the LLC's EIN โ this line only accepts an SSN or ITIN |
| 6a | Foreign tax identifying number | Chinese tax residents enter their 18-character national ID number (17 digits plus a final digit or X) | Leaving it blank, or putting a passport number here instead |
| 6b | Foreign tax identifying number not legally required | China does issue tax IDs โ don't check this box | Checking it to avoid having to enter anything |
| 7 | Reference number | Optional; can be your platform account number | โ |
| 8 | Date of birth | Month-Day-Year (MM-DD-YYYY) | Writing it in the Chinese year-month-day format |
| 9 | Country of residence under treaty | Your country of tax residence, not your citizenship โ these can differ | Entering your citizenship, or entering Hong Kong |
| 10 | Special rates and conditions | Only complete this when actively claiming a treaty rate | Filling it in even when you don't receive income of that type |
On the signature page: sign in your own name, consistent with line 1, and use month-day-year for the date. If someone else is signing on your behalf, proper authorization is required and their signing capacity needs to be noted on the form.
Lines 5 and 6 when you have no SSN or ITIN
Leaving line 5 blank is perfectly normal. Where it gets important: lines 6a and 6b can't both be empty. The form requires you to either provide a foreign tax ID on 6a, or check 6b to indicate one isn't legally required. Chinese tax residents have tax IDs, so go straight to 6a and put in your 18-digit national ID number โ don't touch 6b.
There are only two situations where a US tax ID is actually mandatory on this form: claiming withholding exemption for certain annuities, or submitting the form to a partnership conducting a US trade or business. For treaty rate claims in other contexts, a foreign tax ID on 6a satisfies the requirement. You don't need an ITIN to fill out this form โ when an ITIN is actually required is a separate question covered in the ITIN guide.
If both 6a and 6b are blank, the form is incomplete. The payer may return it or default to 30% withholding. And checking 6b doesn't substitute for the tax ID a treaty claim requires.
Part II: the tax treaty section โ should you fill it out?
Most cross-border e-commerce sellers can skip Part II entirely. It only matters when you're receiving US-source dividends, interest, or royalties and want to reduce the withholding rate. Product sale proceeds generally don't fall into those categories.
There's also a prerequisite that trips people up: you need to be a Chinese tax resident, not just a Chinese citizen. The two aren't the same thing.
| Income type | Treaty article | Treaty rate | Default rate |
|---|---|---|---|
| Dividends | Article 9 | 10% | 30% |
| Interest | Article 10 | 10% | 30% (bank deposit interest and similar items may be exempt from withholding under US domestic law) |
| Royalties | Article 11 | 10%; 7%โ10% by category | 30% |
If you do need to fill Part II, line 9 gets "China," and line 10 specifies the article, rate, and income type โ for example: Article 9, 10%, dividends.
When not to complete Part II: you're not actually a Chinese tax resident (if you live in Singapore or the US, look at your actual country of residence's treaty instead); you're a Hong Kong resident โ the US-China income tax treaty doesn't extend to Hong Kong, and the US has no separate income tax treaty with Hong Kong; you're a Taiwan resident, similarly not covered; you're also a US tax resident, in which case W-9 applies; your income is effectively connected to a US trade or business, which means W-8ECI; or you simply don't receive income of these types.
One thing worth stating plainly: this form is signed under penalty of perjury. Claiming a treaty benefit you don't actually qualify for means the payer withholds less than they should, and the IRS can come after you for the difference.
How long it stays valid and when to resubmit
A W-8BEN is valid from the date of signature through December 31 of the third calendar year after signing. Sign in 2026, and it's valid through December 31, 2029. It doesn't expire at the end of each calendar year, and it doesn't stay valid indefinitely โ it lands somewhere between those two extremes.
You need to resubmit when your country of tax residence changes, your citizenship or status changes, or the address on the form is no longer accurate. If you become a US citizen or tax resident, you're required to notify the payer within 30 days. Some platforms will also ask for a fresh form when you update your bank account or address, regardless of when your current one expires.
Eight reasons forms get kicked back
- Permanent residence address on line 3 shows a US address, a P.O. box, or a forwarding address.
- Both lines 6a and 6b are blank, or a Chinese resident checked 6b.
- Name doesn't match the account or official documents โ including pinyin spelling, name order, or middle name handling.
- Date formatted as day-month-year; the form requires month-day-year.
- Missing signature, missing date, or signature doesn't match the name on line 1; platform requires a handwritten scan and a typed signature was submitted instead.
- A company or entity account used the individual form โ entities need W-8BEN-E.
- Part II has mismatched country, article, and income type, or the country of residence doesn't match the country issuing the tax ID.
- Corrections made with correction fluid or handwritten over the original, scan is blurry or pages are cut off, or an outdated version of the form was used. Any corrections should be made on a fresh form.
W-8BEN vs. W-8BEN-E
Individuals use W-8BEN. Companies, partnerships, and other entities use W-8BEN-E. The entity version requires classifying the entity under both Chapter 3 and Chapter 4 of the tax code, and treaty claims are handled separately โ it's considerably more involved. The situation most likely to produce the wrong form: a US single-member LLC owned by a foreign individual. The details for that structure are covered in a separate guide.
What "beneficial owner" means here โ and what it doesn't
Under US tax law, the beneficial owner is the person who is required to include that payment in their own income โ not an agent collecting on someone else's behalf, not a nominee, not an intermediary. This is completely separate from the FinCEN beneficial ownership concept, which asks who owns or controls a company. Same phrase, two different meanings. Don't mix them up.
Where to get the form
Search "Form W-8BEN" on the IRS website. The current version is dated October 2021. The form must be completed in English โ there's no official Chinese-language version that can be submitted. The line-by-line table above is the reference for Chinese speakers.
