The W-8 forms can be challenging for nonresidents to navigate.
However, understanding these forms is essential, particularly if you plan to earn income in the U.S.
To make things easier, we’ve compiled all the essential details about W-8 forms in this helpful guide.
Let’s dive into what the W-8 forms are used for and why they’re important!
What is a W-8 Form and what is it used for?
A W-8 form is an IRS document used by foreign individuals and entities to verify their nonresident status and claim tax treaty benefits to lower U.S. withholding tax.
Typically, nonresidents are taxed at a 30% rate on income earned from U.S. sources. However, the W-8 forms help nonresidents lower this tax rate if a tax treaty exists between their country and the U.S.
Without a completed W-8 form, nonresidents are subject to the full 30% tax rate, even if they qualify for a lower rate through a treaty.
W-8 vs W-9 forms – what’s the difference?
The W-8 and W-9 forms serve different purposes and apply to different groups of people.
While W-8 Forms are used by nonresidents only, W-9 Forms are used by U.S. citizens, permanent residents, and businesses to provide their taxpayer identification information to employers, banks, or other financial institutions.
The W-9 form is not associated with any tax treaty benefits, as it is only for U.S. taxpayers. It is commonly used for contractors, freelancers, and vendors who need to report their income for U.S. tax purposes.
So, in summary, W-8 forms are for nonresidents who may qualify for tax treaty benefits, while W-9 forms are for U.S. taxpayers.
Which countries have tax treaties with the U.S.?
The U.S. has tax treaties with over 65 countries, aimed at preventing double taxation and lowering tax burdens on residents of treaty countries who earn income in the U.S.
Some countries with U.S. tax treaties include Canada, the United Kingdom, Germany, India, Japan, and South Korea.
These treaties allow residents from these countries to benefit from reduced tax rates on certain types of income, like wages, scholarships, and investment income.
For example, a student from Germany may qualify for a lower tax rate on their U.S.-based income, or even a complete exemption in some cases.
Eligibility varies by country and income type, and individuals must file a W-8BEN form (for individuals) or W-8BEN-E form (for entities) to claim these benefits.

Who needs to complete a W-8 form?
If you are a non-U.S. citizen or a foreign-registered business entity that receives income from U.S. sources, you generally must complete a W-8 form.
U.S. payers (such as employers, universities, or investment platforms) are required by law to withhold a flat 30% tax on income paid to foreign individuals or entities. Submitting the correct W-8 form allows you to prove your nonresident status and drastically reduce or eliminate this tax withholding.
5 Common scenarios where you need a W-8 form:
- International students & scholars (F-1, J-1, M-1 visas): If you receive scholarships or fellowships from a U.S. university;
- Foreign freelancers and independent contractors: If you provide digital services, consulting, or project work to a U.S.-based company from your home country.
- Non-U.S. investors: If you earn passive income from U.S. sources, such as dividends from U.S. stocks, interest on investments, or rental income from U.S. real estate.
- Content creators and digital sellers: If you monetize a YouTube channel, sell products on U.S. e-commerce marketplaces (like Amazon or Etsy), or publish digital content via U.S. platforms.
- Foreign businesses and entities: If your foreign-registered corporation, partnership, or organization receives income or conducts trade effectively connected to the United States.
There are 5 types of W-8 forms:
W-8BEN
For individuals to claim tax treaty benefits and reduce tax withholding.
This is the most commonly used W-8 form. Read more about form W-8BEN here.
W-8BEN-E
The W-8BEN-E is similar to the W-8BEN but instead of individuals, it is used by entities, such as businesses, to claim tax treaty benefits.

For intermediaries, partnerships, and other entities that receive income on behalf of others.
| Form type | Who it's for | Main purpose |
|---|---|---|
| W-8BEN | Foreign individuals | Claim treaty benefits on U.S. income (scholarships, dividends) |
| W-8BEN-E | Foreign entities/businesses | Claim treaty benefits on business-level income |
| W-8ECI | Foreign trades/businesses | For income "effectively connected" to a U.S. trade or business |
| W-8EXP | Foreign governments and tax-exempt organizations | Claim complete tax exemption |
| W-8IMY | Intermediaries and partnerships | For entities receiving income on behalf of others |
Do I have to complete a W-8 Form?
That depends.
In many cases, a W-8 form will be required for nonresidents if they receive income from U.S. sources.
This form serves as a declaration to the IRS that the individual or entity is a nonresident taxpayer and is therefore subject to different tax rules compared to U.S. residents.
When is the W-8 Form not required?
A W-8 form may not be necessary for nonresidents who do not have any income or financial transactions connected to the U.S., or if their income is exempt from withholding.
In short, if you’re a nonresident in the U.S. earning income from U.S. sources, filing a W-8 form is crucial to ensure proper tax treatment and avoid higher withholding rates.
When and where should I file a W-8 Form?
Nonresidents should submit their W-8 forms before receiving any income from a U.S. source in order to ensure the correct withholding tax rate is applied.
Typically, this means providing the form to the U.S. payer or institution that will be making the payments, such as an employer, university, or financial institution.
It’s essential to complete and submit the form in advance, as failing to do so may result in automatic withholding at the standard 30% rate, even if you qualify for a lower rate under a tax treaty.
For example, students and scholars should submit their W-8 form to their university or payroll department if they are receiving a stipend, scholarship, or wages.
W-8 Form validity period
Once submitted, W-8 forms are generally valid for three years. However, if there are changes to your residency status or other relevant information, you may need to complete a new form.
Frequently asked questions about W-8 forms
Can a U.S. citizen or green card holder fill out a W-8 form?
No. W-8 forms are strictly reserved for foreign individuals and foreign entities. If you are a U.S. citizen, permanent resident (green card holder), or a resident alien for tax purposes, you must fill out a Form W-9 (Request for Taxpayer Identification Number and Certification) instead.
What happens if I do not submit a W-8 form?
If you fail to provide a completed, valid W-8 form to your U.S. withholding agent, they are legally required to assume you are uncertified and must withhold a flat 30% backup tax from your gross income. You will not be able to claim any lower tax rates provided by a tax treaty between your home country and the United States.
Does a W-8 form require an ITIN or SSN?
It depends on whether you’re claiming tax treaty benefits.
A basic W-8 form used only to certify your foreign status doesn’t require a U.S. Taxpayer Identification Number (SSN or ITIN). But to claim a reduced withholding rate under a U.S. tax treaty, you generally need to provide either a U.S. TIN (SSN/ITIN) or your foreign tax identification number (FTIN) from your home country. The main exception: if your home country doesn’t issue tax ID numbers, you can certify that instead of providing one.
