The United States has income tax treaties with a long list of countries. Founders hear about them and reach the same conclusion: there is a treaty with my country, so my U.S. tax should be lower.
That conclusion is right for some people and wrong for others, and the dividing line is not the one most people expect. It is not about your passport. It is about whether the IRS counts you as a U.S. person. If it does, almost every treaty contains a clause that takes the benefit back.
This page explains what a treaty actually gives you, who it gives it to, and which piece of paper you have to hand over to get it.
What a tax treaty actually does
A tax treaty is an agreement between the United States and one other country. Under it, residents of that other country may be taxed at a reduced rate, or not taxed at all by the United States, on certain items of income they receive from U.S. sources. The agreement works in both directions, so U.S. citizens and residents may get a similar reduction in the other country on income they earn there.
Two words in that description do the work.
The first is residents. A treaty gives benefits to residents of the two countries that signed it. Being born somewhere, or holding a passport, is not the test.
The second is certain items of income. A treaty is not a discount on your whole tax bill. It works item by item. One article of the treaty covers one kind of income, and the reduction it gives applies only to that kind. A treaty may reduce U.S. tax on one type of payment you receive and do nothing at all for the next type.
Which items are covered, and at what rate, is set out country by country in the IRS tax treaty tables. Table 1 gives the withholding rates on interest, dividends, royalties and other income that is not personal service income. Table 2 covers compensation for personal services. Note that these tables used to sit inside IRS Publication 901 and no longer do. Publication 901 now tells you to go to IRS.gov for them. The treaty text itself is the final authority, and the IRS publishes every treaty.
The saving clause
Here is the part that surprises people, and it is the reason this page exists.
Most U.S. income tax treaties contain a provision called a saving clause. It says the United States can still tax its own citizens and residents as if the treaty had not been signed. The point of the clause is to stop U.S. citizens and residents from using a treaty to avoid U.S. tax on U.S. income.
So if the IRS counts you as a U.S. person, the treaty with your other country will usually not reduce your U.S. tax. The treaty still exists, and it still does something for you, but what it does is limit the tax that the other country charges you. It does not shield you from the IRS.
How you claim a benefit
If you are entitled to a treaty benefit, you do not claim it by writing to the IRS. You claim it by giving a form to the person or company who is about to pay you, which the IRS calls the withholding agent.
- Form W-8BEN if you are an individual.
- Form W-8BEN-E if the recipient is an entity.
- Form 8233 if the payment is compensation for personal services you performed.
The payer keeps the form and withholds at the treaty rate instead of the standard rate. Form 8233 is the one exception to that. The withholding agent keeps a copy, gives you a copy, and must forward a copy to the IRS within 5 days of accepting it. Either way, you are not the one who sends it. If you never give the payer the form, they will withhold at the standard rate, and the treaty will not help you even though you qualified for it.
Form 8833, and the penalty for skipping it
There is a second, separate step in one situation. If you take a position on your tax return that a treaty overrides or modifies a provision of U.S. tax law, you have to disclose that position by attaching Form 8833 to your return.
If you were required to file Form 8833 and did not, the penalty under IRC section 6712 is $1,000 for each failure, and $10,000 for each failure if the taxpayer is a C corporation. That penalty is not the tax. It is charged on top of whatever the tax turns out to be. The IRS can waive it if you show that the failure was for reasonable cause and that you acted in good faith.
Not every treaty benefit needs this form. The IRS lists exceptions to the disclosure requirement. They include a reduced rate of withholding on interest, dividends, rent, royalties and other fixed or determinable annual or periodic income; a treaty exemption covering dependent personal services, pensions, annuities, social security, or the income of students, trainees, teachers, artists and athletes; a reduction under a social security or diplomatic agreement; positions already reported by a partnership, estate or trust you are a member of; and cases where the items you would have to disclose total no more than $10,000. The form is aimed at the positions that push against the statute, not at the ordinary ones.
🇺🇸 If the IRS counts you as a U.S. person
Start by lowering your expectations of the U.S. side. The saving clause means that a treaty between the United States and the country you came from, or the country you now live in, will generally not reduce the U.S. tax on your income. The United States taxes you the way it taxes any other U.S. person.
What the treaty is actually for, in your case, is the other country. If you earn income in a treaty country while the IRS counts you as a U.S. person, the treaty limits what that country may charge you. You claim that benefit under that country's rules, not with the IRS.
There are exceptions written into the treaties themselves. Saving clauses normally list a small number of articles that survive them, so that even a U.S. person can still rely on those articles. Which ones survive is written in the treaty text, and it is not the same in every treaty. If somebody tells you that a treaty cuts your U.S. tax as a U.S. person, ask them to point at the article and at the exception in the saving clause. That request ends most of these conversations.
🌏 If it does not
This is where a treaty is worth real money.
If you are a resident of a country that has an income tax treaty with the United States, and you receive an item of U.S.-source income that the treaty covers, the U.S. tax on that item can be reduced or removed. The saving clause does not apply to you, because you are not a U.S. citizen or a U.S. resident.
Three things decide whether you actually get it.
- You are a resident of the treaty country. The treaty runs between two countries. If you live in a third country, the treaty between the United States and your country of origin does nothing for you.
- The income is an item the treaty covers. Check the IRS tax treaty tables for your country, then check the treaty text. Do not assume that a reduction on one type of income applies to another.
- The payer has your form. Give the withholding agent Form W-8BEN, Form W-8BEN-E, or Form 8233, whichever fits. The payer applies the treaty rate. Nobody at the IRS will apply it for you.
If a payer has already withheld at the standard rate because you sent the form late, the money is not gone, but getting it back means filing a return and waiting. Sending the form before the first payment is far easier than recovering the tax afterwards.
Where the two lanes split
| 🇺🇸 U.S. person | 🌏 Not a U.S. person | |
|---|---|---|
| Does the treaty lower your U.S. tax? | Usually no. The saving clause lets the U.S. tax you as if the treaty did not exist | Yes, on the income items the treaty covers |
| Does the treaty lower tax in the other country? | Yes. That is where your benefit is | Not the question this page answers |
| Who you hand the form to | Nobody, for U.S. purposes | The withholding agent who pays you |
| Which form | Not applicable | W-8BEN (individual), W-8BEN-E (entity), Form 8233 (personal services) |
| Form 8833 disclosure | Required if you take a treaty position that overrides U.S. tax law | Same rule. $1,000 per failure, $10,000 if the taxpayer is a C corporation |
| Where you look up your rate | The treaty text, plus the other country's rules | IRS tax treaty tables, Table 1 and Table 2, then the treaty text |
Common mistakes
🇺🇸 If the IRS counts you as a U.S. person
- Assuming that because a treaty exists with your home country, your U.S. tax goes down. The saving clause is in almost every treaty, and it exists precisely to stop that.
- Reading an article of a treaty on its own and stopping there. The saving clause sits in a different article and can cancel what you just read.
- Assuming that a green card you no longer use settles the question on its own, in either direction. Holding a green card makes you a U.S. resident for tax purposes, and simply not using it changes nothing. But if you also live in the treaty country and the treaty's tie-breaker article makes you a resident there, Treasury regulations let you be taxed as a nonresident alien for U.S. income tax: you file Form 1040-NR and disclose the position on Form 8833 (26 CFR 301.7701(b)-7). That is a position you have to take and disclose. It does not happen by itself.
🌏 If it does not
- Qualifying for a treaty rate and never telling the payer. Without Form W-8BEN in their file, the payer withholds at the standard rate.
- Sending the W-8BEN to the IRS. It goes to the company paying you. The IRS does not want it.
- Treating a treaty as a discount on everything. It applies item by item, and an item the treaty does not name is taxed under the normal rules.
- Taking a treaty position that overrides U.S. tax law and skipping Form 8833. That is $1,000 per failure, or $10,000 per failure if the taxpayer is a C corporation, separate from the tax itself.
FAQ
My country has a tax treaty with the United States. Does that mean I pay less U.S. tax?
Only if the IRS does not count you as a U.S. person, and only on the items of income that the treaty covers. If the IRS counts you as a U.S. person, the saving clause in most treaties allows the United States to tax you as if the treaty were not there.
What is a saving clause?
It is a provision found in most U.S. income tax treaties. It preserves the right of the United States to tax its own citizens and residents as if the treaty had not come into effect. It is the reason a treaty rarely lowers a U.S. person's U.S. tax bill.
How do I claim a treaty benefit?
You give a form to the person or company paying you, which the IRS calls the withholding agent. Individuals use Form W-8BEN. Entities use Form W-8BEN-E. Compensation for personal services uses Form 8233. You do not send these forms to the IRS.
Do I file Form W-8BEN with my tax return?
No. Form W-8BEN goes to the payer, and the payer keeps it. It is not attached to a return and it is not mailed to the IRS.
When do I need Form 8833?
You need it when you take a position on your tax return that a treaty overrides or modifies a provision of U.S. tax law. The IRS excepts a number of ordinary benefits from the disclosure, including a reduced rate of withholding on interest, dividends, rent and royalties, treaty exemptions for dependent personal services, pensions and the income of students, trainees and teachers, and any case where the items you would have to disclose total no more than $10,000.
What happens if I should have filed Form 8833 and did not?
The penalty is $1,000 for each failure to disclose, and $10,000 for each failure if the taxpayer is a C corporation. It is charged in addition to any tax you owe. The IRS can waive it if you show reasonable cause and good faith.
Where do I find out what my country's treaty covers?
Start with the IRS tax treaty tables. Table 1 gives the withholding rates on interest, dividends, royalties and similar income, and Table 2 covers compensation for personal services. These tables used to be printed inside IRS Publication 901 and were moved to IRS.gov, so an old copy of the publication will not have them. The treaty text itself is the final authority, and the IRS publishes it.
Does the treaty apply automatically once I qualify?
No. A treaty benefit has to be claimed. For payments made to you, that means the withholding agent has your W-8BEN, W-8BEN-E or Form 8233 before the payment is made. If nobody has the form, the standard withholding applies.
