W-8BEN-E for a Korean Company: Chusik Hoesa, Yuhan Hoesa, or Sole Proprietor — Real Treaty Rates, Line-by-Line, and a Sample PDF
This article was created with AI assistance and has not been reviewed by a human editor. It is provided for general informational purposes only and does not constitute tax, legal, or financial advice.
Treaty articles and rates on this page are checked against the 1976 US–Korea Convention signed at Seoul on 4 June 1976 (in force 20 October 1979) — last verified October 2026. The IRS PDF (irs.gov/pub/irs-trty/korea.pdf) is that convention with no protocol, and its 1970s article numbers (Business Profits = Article 8, not 7) are the ones that apply.
AI-generated imageYour Korean Chusik Hoesa (주식회사) just invoiced a US client — an MCN, game studio, SaaS company, or agency — and the client's finance team is now asking for a completed W-8BEN-E before they'll release payment. That's one of the two most common reasons Korean company owners end up on this page.
The other is the 서학개미 (overseas-stock retail investor) path: a Korean company or high-net-worth account at Toss Securities, Mirae Asset, Kiwoom, or Interactive Brokers Korea that holds US securities. The broker asks for a W-8BEN or W-8BEN-E so it can apply the correct US withholding on dividends — 15% under Article 12(2)(a) in the ordinary case, not a made-up 0%.
If you're not incorporated — a 개인사업자 (individual business registration) operating under your own name, even if you also have a Business Registration Number — the shorter W-8BEN applies instead: start the W-8BEN wizard. This page covers incorporated businesses: Chusik Hoesa, Yuhan Hoesa, and Yuhan Chaegim Hoesa.

Which Korean company type are you actually dealing with?
The answer depends on your company's legal form, not your revenue and not whether you have a BRN:
- 개인사업자 (individual business registration): Not a separate legal entity — you're treated as an individual for US tax purposes. You use the shorter W-8BEN, not W-8BEN-E. A Business Registration Number does not change that: sole proprietors receive the same-format BRN as companies.
- Chusik Hoesa (주식회사): The most common Korean company type, often written "Co., Ltd." in English. It is on the US per se corporation list — always Corporation for US tax purposes, with no ability to elect a different classification via Form 8832.
- Yuhan Hoesa (유한회사): A limited company. Not on the per se list, but defaults to Corporation because its members have limited liability. Electing partnership or disregarded-entity treatment requires filing Form 8832.
- Yuhan Chaegim Hoesa (유한책임회사): The LLC-type company form introduced in 2012. Still a Corporation by default; disregarded or partnership treatment is an election on Form 8832, not the starting point.
The clearest way to tell an incorporated company from a 개인사업자: the company has both a Business Registration Number (BRN, 10 digits) and a Corporate Registration Number (CRN, 13 digits, issued by the court registry). An individual business registration has only the BRN.
Because Korea has a real treaty, this distinction matters: getting the entity type right determines not just which form you file, but which article and rate you can claim in Part III (Lines 14–15). A company cites Article 8(1) only for services performed in the United States with no US permanent establishment; services performed in Korea are not US-source, so Part III (Lines 14a, 14b and 15) stays blank. An individual's pay for services performed in the United States is claimed under Article 18 on Form 8233, not on Form W-8BEN.
Who actually needs to fill in W-8BEN-E?
In short, any Korean Chusik Hoesa, Yuhan Hoesa, or Yuhan Chaegim Hoesa that receives payments from a US business and wants to document its non-US tax status. Common situations:
- Invoicing US clients directly: Your company bills a US-based business for consulting, development, design, or other services — including MCN, creator-studio, and game-publisher invoices.
- US payment platforms: Payouts from Stripe, Amazon, YouTube/AdSense, or similar US-headquartered platforms.
- US shares and dividends via a broker (서학개미): Your company holds US securities through Toss Securities, Mirae Asset, Kiwoom, Interactive Brokers Korea, or a similar broker and receives dividends.
- Royalty or interest income: Your company receives royalty or interest payments from a US source — ordinary interest is generally 12% and royalties are 15% or 10%, never 0% (see rates below).
What happens without a valid form?
Without a submitted W-8BEN-E, a US payer withholds 30% of the gross amount of US-source income (dividends, interest, royalties, and pay for services performed in the United States) under the nonresident-alien presumption rules — not because it treats you as a US person, and even if the treaty gives a lower rate. Fees for services your company performs in Korea are not US-source and carry no US withholding, although the payer may hold the payment until it has a form. With a valid form, dividends are 15% (or 10% in a narrow corporate-holder case), interest is generally 12%, royalties are 15% or 10%, and Article 8(1) gives 0% only for services performed in the United States when the company has no US permanent establishment. Some US platforms and brokers pause payment entirely until a valid form is on file.
The form is never sent to the National Tax Service or the IRS — it stays with the US payer as their own compliance record. Your company still reports the US income as normal on its Korean corporate tax return; W-8BEN-E only affects US withholding at source.
W-8BEN-E line by line: what a Korean Chusik Hoesa actually enters
Below is the official IRS "Line X" numbering exactly as printed on the current form, for an operating Chusik Hoesa, Active NFFE. The most common case is a company paid for services it performs in Korea: that income is not US-source, so Part III (Lines 14a, 14b and 15) stays blank. Lines 14a, 14b and 15 are filled only when the company claims the treaty: for US-source dividends, interest or royalties, or for services performed in the United States with no US permanent establishment (the sample further down). Holding structures and financial institutions follow different rules on some lines — our wizard determines the right answer automatically from your answers.
| Line | What you enter |
|---|---|
| Line 1 | Your company's full legal name exactly as registered (for example, Seoul Tech Co., Ltd.). |
| Line 2 | Country of incorporation: Korea (Republic of). |
| Line 3 | Leave blank — only applies if a disregarded entity is receiving the payment on behalf of its owner. |
| Line 4 | Check "Corporation" for a Chusik Hoesa (always — it is per se), or a Yuhan Hoesa / Yuhan Chaegim Hoesa (by default, unless Form 8832 elected otherwise). A registered partnership checks "Partnership" instead. The "hybrid entity" follow-up question is usually "No" for an ordinary operating company. |
| Line 5 | Chapter 4 (FATCA) status — for a normal operating company with no financial activity, usually "Active NFFE". |
| Line 6 | Your company's actual registered office address (not a virtual mailbox used only for correspondence). |
| Line 7 | Only complete if your mailing address differs from Line 6. |
| Line 8 | Usually blank — a US TIN (EIN) is only required in specific cases your payer will tell you about. |
| Line 9a | Leave blank — a GIIN only applies to financial institutions. |
| Line 9b | Your company's Business Registration Number (BRN, 사업자등록번호, 10 digits, format XXX-XX-XXXXX). This is the tax-purpose foreign TIN — not the 13-digit Corporate Registration Number and not an individual's Resident Registration Number. |
| Line 9c | In practice this is never checked for a registered Chusik Hoesa — a BRN is assigned when the business is registered. |
| Line 10 | Usually blank — only completed at the payer's explicit request. |
| Part II (Lines 11–13) | Not completed for a normal Chusik Hoesa or Yuhan Hoesa — only applies to a disregarded entity or a branch. |
| Line 14a | Only when the company claims the treaty: country of residence for treaty purposes, Korea (Republic of). Blank for services performed in Korea. |
| Line 14b | Only when the company claims the treaty: check Other and write "Holding company test, Article 17". IRS Tax Treaty Table 4 lists Article 17 (Investment or Holding Companies) under Other. Article 17 takes away the dividend, interest, royalty and capital-gains articles if both (a) special measures make Korea's tax on that income substantially less than its general tax on corporate profits and (b) 25% or more of the capital is held of record (or, as the competent authorities determine after consultation, owned directly or indirectly) by persons who are not individual residents of Korea, or by US citizens, who count even when they live in Korea. A company that does not meet both conditions passes the test. Blank for services performed in Korea. |
| Line 14c | Not normally checked — a narrow special case. |
| Line 15 | Only when the company claims the treaty: treaty article, paragraph, rate, and income type (e.g. "Article 8(1)", 0%, "Services" for services performed in the United States with no US permanent establishment, the sample's case). Blank for services performed in Korea. Suggested automatically by the wizard. Never cite Article 7 for Korean business profits. |
| Line 39 (Part XXV) | Check the "Active NFFE" certification, matching Line 5. |
| Part XXX | Signature, printed name, date. Normally signed by a representative director or other authorised signatory. |
Line numbers match the form currently in force (Rev. October 2021). If the IRS issues a new revision, always defer to the numbering on the actual PDF you download.

The BRN vs CRN vs RRN trap on Line 9b: which number actually goes on the form?
This is the single most common identifier mistake for Korean companies — and it is unlike most other countries in this product, because the 13-digit CRN and the 13-digit RRN look the same length.
| Point | What it means |
|---|---|
| BRN (Business Registration Number) | 사업자등록번호, 10 digits, format XXX-XX-XXXXX, issued by the National Tax Service to both companies and sole proprietors. This is the company's tax-purpose foreign TIN for Line 9b; a sole proprietor files Form W-8BEN, which has no Line 9b, and the foreign TIN goes on Line 6a of that form. |
| CRN (Corporate Registration Number) | 법인등록번호, 13 digits, format XXXXXX-XXXXXXX, issued by the court registry only to incorporated companies. It proves legal existence. It is not the tax TIN and should not go on Line 9b. |
| RRN (Resident Registration Number) | 주민등록번호, 13 digits — an individual's identifier, the closest Korean equivalent to a US SSN. It belongs on Line 6a of Form W-8BEN for an individual, not on W-8BEN-E. Same digit count as a CRN, so length alone does not tell them apart. |
| The sole-proprietor trap | A 개인사업자 has a BRN too, but it does not make them a separate entity — they still file the individual Form W-8BEN, never this form. |
| PIPA caution on RRN | South Korea's Personal Information Protection Act (PIPA) restricts private parties from processing RRNs except in narrow, legally-authorized cases. If a private US payer asks a freelancer for an RRN, consider whether disclosure is appropriate, or whether a BRN (if you have one) is a suitable alternative to discuss with the requester. |
Form 8832 can change the Yuhan Hoesa / Yuhan Chaegim Hoesa default (electing partnership or disregarded treatment) — but only if that election has actually been filed. A Chusik Hoesa cannot elect out: it is per se Corporation.
What a completed W-8BEN-E looks like for a Korean Chusik Hoesa
An anonymised example of the claim case: a Chusik Hoesa whose software consultants perform services on site in the United States, with no US permanent establishment (no fixed place of business and no dependent agent there), Active NFFE, claiming Article 8(1) — 0% on that US-source service income, with "Holding company test, Article 17" on Line 14b. Work done only in Korea would leave Part III (Lines 14a, 14b and 15) blank. This is the same signature-ready PDF our wizard produces automatically from the same inputs.
For illustration only — company name, address, director, and BRN are fictional. Example: Seoul Tech Co., Ltd., Seoul, BRN 123-45-67890, Chapter 3 Corporation, FATCA Active NFFE, US–Korea treaty Article 8(1) (Business Profits) 0% for services performed in the United States with no US permanent establishment, Line 14b Other: Holding company test, Article 17.
Treaty rates by income type — the 1976 Convention, still current
Notice the article numbers. This convention predates the modern "Article 7 = Business Profits" pattern used by most other US treaties. If you see Article 7 cited for Korean business income, that is a red flag:
| Income type | Article | Rate |
|---|---|---|
| Services / consulting / software (Business Profits) | Article 8(1) | 0% only for services performed in the United States when the company has no US permanent establishment; profit attributable to a US permanent establishment gets no 0%. A fee for work performed in Korea is not US-source FDAP, so Part III (lines 14a, 14b and 15) stays blank. |
| Dividends (general, including most 서학개미 accounts) | Article 12(2)(a) | 15% of the gross amount |
| Dividends (corporate holder of 10% or more of the voting stock) | Article 12(2)(b) | 10% — only for a corporation that owned at least 10% of the paying corporation's outstanding voting stock during the part of its taxable year before the payment and its whole prior taxable year (if any), when not more than 25% of the payer's gross income for that prior year was interest or dividends (banking, insurance or financing interest, and dividends or interest from subsidiaries 50% or more owned, not counted) |
| Interest (ordinary) | Article 13(2) | 12% of the gross amount |
| Interest beneficially derived by the Government of Korea, a local authority, the central bank, or an instrumentality wholly owned by that Government or that central bank or both and not taxed by Korea on its income | Article 13(3) | 0% — not for an ordinary bank or company |
| Royalties — patents, trademarks, designs, secret processes, know-how, copyrights of scientific works (IP only) | Article 14(1) | 15% — there is no 0% royalty rate in this treaty |
| Royalties — copyrights of literary, dramatic, musical or artistic works, film and broadcast | Article 14(2) | 10% (IRS Tax Treaty Table 1 applies the copyright rate to computer software) |
| Rental of tangible equipment in the company's trade or business | Article 8(1) | 0% with no US permanent establishment and no other activity in the United States (Business Profits — Art. 8(5); not a royalty under Art. 14(4)). A passive lease is not industrial or commercial activity, and no article lowers US withholding on it. |
| Independent personal services (individuals only) | Article 18(1) | Not on this form. Work done in Korea is not US-source: Part II (Lines 9 and 10) of Form W-8BEN stays blank. Pay for services performed in the United States is claimed on Form 8233; Article 18(2) lets the United States tax it if the individual is present 183 days or more in the taxable year, the income exceeds $3,000 in the taxable year, or a fixed base is kept there 183 days or more (then only the income attributable to it). |
You may have seen Korean-language guides claiming a flat 0% treaty rate on royalty income (for example YouTube AdSense or licensing revenue). This is incorrect. There is no 0% royalty rate in the US–Korea treaty. The correct rate is 15% for most IP royalties (Article 14(1)) or 10% specifically for copyright and broadcast-use royalties (Article 14(2)). Equipment rental is not a royalty here: Article 14(4) lists only IP (plus a narrow ships/aircraft case), and Article 8(5) counts the rental of tangible personal property as industrial or commercial activity, so a company's lease in its trade is Business Profits — 0% with no US permanent establishment and no other activity in the United States. Business Profits is Article 8, not Article 7. Independent personal services for an individual are Article 18, not Article 14, and are claimed on Form 8233 for work in the United States.

Frequently asked questions about W-8BEN-E for Korean companies
Direct answers to the questions Korean company owners run into most often when filling this in.
Is there really no 0% royalty rate?
Correct: there is no 0% royalty rate in the 1976 US–Korea treaty. Article 14(1) caps most IP royalties (patents, trademarks, know-how) at 15%. Article 14(2) caps copyright and film/broadcast royalties at 10%. Equipment rental is not in Article 14(4)'s royalty definition: a company's lease in its trade is Business Profits under Article 8(5), 0% with no US permanent establishment and no other activity in the United States. A Korean-language claim of a flat 0% on YouTube AdSense or licensing income is incorrect.
What's the difference between BRN and CRN?
The BRN (사업자등록번호, 10 digits) is the tax ID issued by the National Tax Service and is what a company enters on Line 9b. The CRN (법인등록번호, 13 digits) is the court-registry number that proves the company exists — it is not the tax TIN. A 개인사업자 has a BRN but no CRN, and files Form W-8BEN, which has no Line 9b: the foreign TIN goes on Line 6a of that form.
Do I need to give my RRN to a US company?
South Korea's Personal Information Protection Act (PIPA) restricts private parties from processing Resident Registration Numbers except in narrow, legally-authorized cases. If you are an individual freelancer asked for your RRN by a private US payer, consider whether disclosure is appropriate, or whether your BRN (if you have a business registration) is a suitable alternative to discuss with the requester.
My broker (Toss / Mirae Asset / Kiwoom) is asking for a W-8 — which form?
A Chusik Hoesa, Yuhan Hoesa, or Yuhan Chaegim Hoesa files W-8BEN-E. A 개인사업자 or an individual 서학개미 account files the shorter W-8BEN. The broker uses the form to apply Article 12 dividend withholding (generally 15%), not a 0% rate.
Why does the AI advisor cite Article 8 and not Article 7?
Because the 1976 US–Korea Convention numbers Business Profits as Article 8. Most modern US treaties use Article 7. Citing Article 7 for a Korean entity is a red flag that the source is applying the wrong numbering convention.
What's the difference between Chusik Hoesa, Yuhan Hoesa, and Yuhan Chaegim Hoesa for this form?
A Chusik Hoesa always checks "Corporation" on Line 4 (it is on the US per se corporation list). A Yuhan Hoesa or Yuhan Chaegim Hoesa also defaults to Corporation because members have limited liability, but either can elect a different classification via Form 8832. A 개인사업자 is not on this form at all.
What's Chapter 4 / Active NFFE?
It's a separate FATCA classification from your entity type. A normal trading company with under 50% passive income and assets is usually "Active NFFE".
What treaty rates typically apply?
Under the 1976 US–Korea treaty: services performed in Korea are not US-source, so Part III (Lines 14a, 14b and 15) stays blank. Article 8(1) gives 0% only for services performed in the United States when the company has no US permanent establishment. A company's rental of tangible equipment in its trade is also Article 8(1) (not 14), 0% with no US permanent establishment and no other activity in the United States. Dividends are 15% (Article 12(2)(a); 10% only if a corporate holder meets the 10% voting-stock holding and the 25% interest-and-dividend income tests of 12(2)(b)). Ordinary interest is 12% (Article 13(2); 0% only for the Government of Korea, a local authority, the central bank, or an instrumentality wholly owned by that Government or that central bank or both and not taxed on its income — not an ordinary bank). IP royalties are 15% or 10% (Article 14(1) or 14(2) — never 0%). Our wizard suggests the right one automatically.
Does the form go to the National Tax Service or the IRS?
No — W-8BEN-E goes only to the US payer (client, platform, or broker), never to the NTS or the IRS directly.
How long is W-8BEN-E valid for?
Generally until the end of the third calendar year after signing — a form signed in 2026 is valid through 31 December 2029, provided none of the underlying details change.
What if my company details change?
A change of name, address, entity type, or ownership structure invalidates the existing form, and a new W-8BEN-E is required regardless of the usual three-year cycle.
I'm a 개인사업자, not a company — which form do I use?
The shorter W-8BEN, with your own foreign TIN on Line 6a, not a company CRN. Work you do in Korea is not US-source, so Part II (Lines 9 and 10) of Form W-8BEN stays blank. Pay for services you perform in the United States is claimed on Form 8233 under Article 18, not on Form W-8BEN: Article 18(2) lets the United States tax it if you are present there 183 days or more in the taxable year, the income exceeds $3,000 in the taxable year, or you keep a fixed base there 183 days or more (then only the income attributable to it). This page's line-by-line guidance is for incorporated companies.
Which Line 14b box should my company check?
Only when the company claims the treaty: check Other and write "Holding company test, Article 17". IRS Tax Treaty Table 4 lists Article 17 under Other. Article 17 denies the dividend, interest, royalty, and capital-gains articles if both (a) special measures make Korea's tax on that income substantially less than its general tax on corporate profits and (b) 25% or more of the capital is held of record (or, as the competent authorities determine after consultation, owned directly or indirectly) by persons who are not individual residents of Korea, or by US citizens. A company that does not meet both conditions passes the test. Do not check "No LOB article in treaty". For services performed in Korea, Part III (Lines 14a, 14b and 15) stays blank.
Do I need an accountant to complete this?
Not necessarily for standard cases — an ordinary trading Chusik Hoesa, Active NFFE, common income types can usually be completed with a guided wizard. A holding structure or a complex ownership situation is worth a brief check with a Korean tax professional (세무사) first.
What does it cost to get W-8BEN-E right?
With our guided wizard, $30 per finished, signature-ready PDF for companies (or $5 for sole proprietors) — no subscription.

Common mistakes to avoid
- Citing Article 7 for business profits: The correct article is Article 8. Article 7 is not Business Profits in this treaty.
- Claiming a 0% royalty rate: There is no 0% royalty rate on IP. Use 15% (Article 14(1)) or 10% (Article 14(2)) depending on the royalty type. Do not put equipment rental in Article 14: a company's lease in its trade is Article 8(1), 0% with no US permanent establishment and no other activity in the United States.
- Entering the 13-digit CRN or RRN on Line 9b: Line 9b wants the 10-digit BRN. CRN and RRN are both 13 digits — length alone does not tell them apart.
- Treating a 개인사업자 as eligible for W-8BEN-E: A sole-proprietor registration is not a separate entity. File W-8BEN, not W-8BEN-E.
- Checking No LOB article in treaty: Table 4 lists Article 17 under Other. When the company claims the treaty, check Other and write "Holding company test, Article 17". Article 17 blocks the dividend, interest, royalty, and capital-gains articles if both (a) special measures make Korea's tax on that income substantially less than its general tax on corporate profits and (b) 25% or more of the capital is held of record (or, as the competent authorities determine after consultation, owned directly or indirectly) by persons who are not individual residents of Korea, or by US citizens. A company that does not meet both conditions passes it.
A quick note on Korean corporate tax
This page focuses entirely on US withholding tax — the reason your company needs to fill in W-8BEN-E at all. It doesn't cover Korea's own tax treatment of that income.
How that income is actually taxed once it reaches your Korean company is a question for a licensed 세무사, not something this page — or our wizard — determines for you. W-8BEN-E only affects what a US payer withholds at source; it has no bearing on how Korea taxes your company's profits.
- VAT: Generally not relevant to the US W-8BEN-E itself.
Ready to finish your own W-8BEN-E instead of reading more guides?
The guided wizard asks the same questions covered on this page — directly inside your own form, with the treaty article and rate suggested automatically from the 1976 Convention (Article 8 for a company's services performed in the United States; an individual's US work goes on Form 8233 under Article 18).
