What is Form W-8BEN?
Form W-8BEN is an IRS form that allows non-US individuals to certify their foreign tax status and, if eligible, claim a reduced rate of US withholding tax under an income tax treaty. It is typically provided to a bank, broker, or other payer, not filed directly with the IRS.
If you’re an American living abroad, however, the answer is different. US citizens and individuals who are US tax residents generally should not complete Form W-8BEN, even if they permanently live outside the United States. In most cases, Form W-9 is the correct form instead.
This guide explains who should complete Form W-8BEN, why it’s requested, how it works, and the common mistakes to avoid.

What is Form W-8BEN?
Form W-8BEN exists to help withholding agents determine whether you’re a foreign individual and how much US tax should be withheld from certain payments. If you qualify for treaty benefits, the form can also reduce the amount withheld before you receive your income.
The form generally serves three purposes:
- It certifies that you are a foreign individual for US tax purposes.
- It identifies you as the beneficial owner of the income.
- It allows you to claim treaty benefits if your country has an income tax treaty with the United States and you meet the qualifying conditions.
Example: A non-US investor opens an account with a brokerage that offers US stocks. Before receiving dividend payments, the brokerage requests Form W-8BEN to verify the investor’s foreign status. If the investor qualifies for treaty benefits, the brokerage can generally apply the appropriate withholding rate instead of the default US withholding rate.
That doesn’t mean the form automatically reduces your tax. The treaty rules still need to be met, and the withholding agent relies on the information you provide to determine the correct withholding treatment.
Why was I asked to complete Form W-8BEN?
You’re generally asked to complete Form W-8BEN because a bank, broker, investment platform, or other US payer needs to confirm that you’re a foreign individual before making certain US-source payments.
You might be asked to complete Form W-8BEN if you:
- Open an account that allows you to invest in US shares
- Receive dividends from US companies
- Earn royalties from US sources
- Receive certain interest payments
- Sell products or services through a platform that requests tax documentation
- Receive other types of US-source income that require withholding documentation
For most people, receiving the request is simply part of opening an investment account or receiving income connected to the United States.
Common misconception: Working for a US company doesn’t automatically mean you need Form W-8BEN. The correct form depends on your tax status and the type of income.
For employees, Form W-4 generally applies, while nonemployees may need Form W-8BEN, Form W-8ECI, or Form 8233, depending on the situation.

The easiest way to determine whether Form W-8BEN applies is to look at your US tax status, not where you currently live.
Can I use Form W-8BEN if I’m a US citizen living abroad?
No. Simply living outside the United States doesn’t change your status as a US person for tax purposes. If you’re a US citizen, you should not certify that you’re a foreign individual by completing Form W-8BEN. In most cases, you’ll provide Form W-9 instead.
US citizens generally remain subject to US tax on their worldwide income regardless of where they live. Formally relinquishing citizenship can change that status, but final-year filing and expatriation requirements may still apply.
There are situations where the correct form isn’t immediately obvious. For example, Green Card holders, former Green Card holders, and individuals whose US tax residency has changed may need to consider additional IRS residency and treaty rules before determining which form applies.
How do I fill out Form W-8BEN?
Completing Form W-8BEN is usually straightforward if you have the correct information. The current IRS form is divided into three parts. While every situation is different, most people will complete the following sections.
Step 1: Complete Part I – Identification of beneficial owner. This section identifies who you are and establishes your foreign status.
You’ll usually be asked to provide:
- Your full legal name
- Country of citizenship
- Permanent residence address
- Mailing address, if different
- A US taxpayer identification number, such as an SSN or ITIN, if required
- Your foreign tax identification number, if required
- Confirmation that an FTIN is not legally required, where applicable
- Date of birth, when required
- Any reference number requested by the withholding agent
Use your permanent residence address, not simply a mailing address or post office box. If you’re claiming treaty benefits, this address should normally reflect the country where you’re considered a tax resident under the applicable income tax treaty.
Step 2: Complete Part II – Claim of tax treaty benefits (if applicable). Enter your country of tax residence on line 9 if you’re claiming treaty benefits. You only need to complete line 10 if your treaty claim requires additional information, such as the applicable treaty article, type of income, reduced withholding rate, or other treaty conditions.
If you’re not claiming treaty benefits, you can usually leave Part II blank.
Step 3: Complete Part III – Certification. By signing, you’re certifying, under penalties of perjury, that the information you’ve provided is correct and that you’re entitled to the status or treaty benefits you’ve claimed.
Take a moment to review the form before signing. Even small errors, such as selecting the wrong treaty country or providing outdated information, can delay payments or result in the wrong amount of tax being withheld.
Filing tip: Form W-8BEN is normally given to the bank, broker, investment platform, or other withholding agent that requested it. You don’t usually send it directly to the IRS.
What tax benefits can I claim with Form W-8BEN?
Form W-8BEN doesn’t create a tax benefit on its own. Instead, it allows eligible individuals to claim reduced US withholding tax under an applicable income tax treaty.
Under US tax law, certain US-source fixed or determinable annual or periodical income paid to a foreign person is generally subject to 30% withholding unless a lower statutory or treaty rate applies. Income effectively connected with a US trade or business is subject to different rules.
Keep in mind that Form W-8BEN only affects US withholding tax. It doesn’t eliminate any tax you may owe in your country of residence, and you may still need to report the income under your local tax rules.
What happens if I don’t submit Form W-8BEN?
If you don’t submit Form W-8BEN when requested, the payer may apply the default 30% US withholding tax or another applicable withholding rate to certain US-source income until they receive valid documentation.
Without a completed form, you could experience:
- 30% withholding on certain US-source income, even where a lower treaty rate might otherwise apply
- Delayed payments while your tax status is verified
- Requests for updated documentation before future payments are processed
If you qualify for a reduced treaty rate, submitting Form W-8BEN before you receive payment can help ensure the correct withholding rate is applied from the start.
What’s the difference between Form W-8BEN and Form W-8BEN-E?
Form W-8BEN is generally for foreign individuals, while Form W-8BEN-E is generally for foreign entities that are the beneficial owners of income. However, some foreign partnerships, trusts, intermediaries, and flow-through entities use Form W-8IMY instead.
If you operate as a sole proprietor, don’t assume you need Form W-8BEN-E simply because you run a business. The correct form depends on who legally receives the income and how the business is classified for tax purposes.
