Nonresident Crypto Taxes: W-8BEN, 1099-DA and US Gains

Short answer: a nonresident gives a US crypto exchange Form W-8BEN, not Form W-9, and never sends it to the IRS. A valid W-8BEN documents you as a foreign person, so the exchange does not issue you Form 1099-DA. Your gains are generally not US-taxed if you spent under 183 days in the US.

A US exchange asking a non-US customer for tax forms is a routine part of onboarding, but the request raises real questions. Which form is yours? What does signing it certify? Will the exchange report you to the IRS? And does the United States tax a foreigner's crypto gains at all?

This guide answers those questions for an individual account holder who is not a US citizen and not a US tax resident. It is not written for exchanges running their own compliance programs. I am Chris Herbst, founder of CountDeFi. We are crypto tax accountants: we reconcile crypto histories and produce the reports a client's own CPA or tax adviser files from. We are not a CPA firm. We work with clients in the US, the UK, Canada, South Africa and elsewhere, and cross-border histories are a regular part of that work, which is why the questions below come up so often.

What a US Crypto Exchange Asks a Nonresident For

A US exchange is a broker for tax purposes. It must report customer sales to the IRS unless the customer is exempt from that reporting. The onboarding tax step exists to establish which customers are exempt, and the form you sign is how it finds out.

Which tax form does a nonresident give a US exchange?

Form W-8BEN. The IRS calls it the Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting (Individuals). It is the individual version; companies and other entities use different W-8 forms.

Why not Form W-9?

Form W-9 is for US persons. The IRS says to use Form W-9 to provide your correct Taxpayer Identification Number (TIN) to the person who is required to file an information return with the IRS. A US citizen living abroad is still a US person and signs a W-9, not a W-8BEN. Signing the wrong one misstates your status under penalties of perjury.

Do you send Form W-8BEN to the IRS?

No. The instructions say plainly: do not send Form W-8BEN to the IRS. Instead, give it to the person who is requesting it from you. On an exchange that means completing it in the onboarding flow or uploading it when asked.

What else is usually requested at onboarding?

Identity verification, proof of address and the source-of-funds questions are the exchange's own customer checks, not tax forms. The tax step is the W-8BEN. The two meet at one point: the address and country you give for identity checks should match the permanent residence address on the W-8BEN, because a mismatch is exactly what an exchange's review flags.

How To Fill In Form W-8BEN as a Crypto Account Holder

The form is short. The lines that matter most to a crypto customer are the ones that decide whether the certificate is valid and whether a treaty claim is made.

Part I: who you are

Part I asks for your name, country of citizenship, permanent residence address and mailing address. The instructions define the permanent residence address as the address in the country where you claim to be a resident for purposes of that country’s income tax, and tell you not to show the address of a financial institution, a post office box, or an address used solely for mailing.

Do you need a US tax number on the W-8BEN?

Usually not for an exchange account. A US taxpayer identification number becomes relevant when you claim treaty benefits: the instructions say that to claim certain treaty benefits, you must complete line 5 by submitting an SSN or ITIN, or line 6 by providing a foreign tax identification number (foreign TIN).

Why the form asks for your date of birth

Line 8 asks for it when you are documenting yourself as an account holder with a financial institution. The instructions set the format: MM-DD-YYYY. A date entered in the day-first order used in most countries is a common reason a form is bounced back.

Part II: the treaty claim

Part II, line 9, is where you identify your country of residence if you are claiming treaty benefits. The IRS explains that under income tax treaties residents (not necessarily citizens) of foreign countries may be eligible to be taxed at a reduced rate or exempt from U.S. income taxes on certain items of income, and that those rates and exemptions vary by country and by item. For an account that only buys and sells crypto, a treaty claim often changes nothing, because the gains are generally not taxed in the first place (see below). It matters more when the account pays you income.

Part III: what you certify

You sign under penalties of perjury. For a digital asset broker, the regulations add a specific certification for individuals: the certificate must include a certification that the beneficial owner has not been, and at the time the certificate is furnished reasonably expects not to be, present in the United States for a period aggregating 183 days or more during each calendar year to which the certificate pertains. Read that line before you sign if you spend long periods in the US.

How Long a W-8BEN Stays Valid, and When To Replace It

A W-8BEN is not permanent. Exchanges ask for a fresh one on a cycle, and some ask again when your details change.

When does a W-8BEN expire?

Generally at the end of the third calendar year after the year you sign it. The IRS gives the rule and an example: a form signed on September 30, 2015, remains valid through December 31, 2018, unless a change in circumstances makes information on it incorrect.

What counts as a change in circumstances?

Anything that makes a line on the form wrong. The instructions give the key example for account holders: a change of address to an address in the United States is a change in circumstances. A move within the same foreign country, or to another foreign country, generally is not, though a new country of residence can still affect a treaty claim.

How quickly must you tell the exchange?

Within 30 days. If a change makes your form incorrect, you must notify the withholding agent, payer, or FFI with which you hold an account within 30 days of the change in circumstances and you must file a new Form W-8BEN or other appropriate form. If you become a US tax resident, the new form is usually a W-9.

What Happens If You Give No Form, or the Wrong One

An exchange that cannot document you as foreign cannot treat you as exempt from reporting. The rules then decide your status for it.

Presumption rules

Where a broker has not collected a valid certificate, the regulations require it to apply presumption rules to classify the customer, and they bar it from treating a customer as foreign when it has actual knowledge or reason to know that the customer is a U.S. person.

Backup withholding

Backup withholding is the US mechanism for payees who do not provide a correct TIN. The IRS describes it as withholding at the current rate of 24 percent, taken from payments to ensure the IRS receives the tax due. A customer the exchange treats as a US person without a valid TIN is exposed to it, which is one more reason to get the form right the first time.

Signing a W-9 by mistake

If you signed a W-9 as a non-US person, tell the exchange and replace it with a W-8BEN. Until you do, the exchange treats you as a US person, which means information returns in your name and possibly a US taxpayer number request you cannot meet.

Does a Nonresident Get Form 1099-DA?

Form 1099-DA is the new broker form for digital asset sales. The IRS says brokers must report gross proceeds for transactions effected on or after Jan. 1, 2025, and must report basis on certain transactions effected on or after Jan. 1, 2026. For a documented nonresident, the answer to whether you get one is generally no.

Why a valid W-8BEN means no 1099-DA

The broker regulations say that no return of information is required to be made by a broker with respect to a customer who is considered to be an exempt foreign person. A US digital asset broker may treat you as an exempt foreign person if, before paying you the proceeds of a sale, it holds a beneficial owner withholding certificate it can treat as valid. For an individual, that certificate is the W-8BEN.

What if you receive a 1099-DA anyway?

It usually means the exchange has you on file as a US person, or your certificate lapsed. Ask the exchange which status it holds for you and send a current W-8BEN. Do not ignore it: Form 1099-DA is an information return the broker files with the IRS as well as sending to you. Our guide to what Form 1099-DA means for your tax return explains what the form shows and leaves out.

Does no 1099-DA mean no record anywhere?

No. The exchange keeps your transaction history, and your home country may receive information about your account under its own reporting rules. Not receiving a US form tells you about US information reporting only; it says nothing about what you owe at home.

Does the US Tax a Nonresident's Crypto Gains?

For most nonresident individuals who simply buy, sell and swap crypto, the answer is no, but the rule turns on days of presence and on whether the gains are connected with a US business.

The 183-day rule for capital gains

Publication 519 states the general rule: if you were in the United States for less than 183 days during the tax year, capital gains (other than gains listed earlier) are tax exempt unless they are effectively connected with a trade or business in the United States. Publication 519 also says these rules do not apply to the sale or exchange of a U.S. real property interest, which has its own rules.

What if you were in the US for 183 days or more?

Then the rule flips for a nonresident. Publication 519 says that your net gain from sales or exchanges of capital assets is taxed at a 30% (or lower treaty) rate, where net gain means US-source capital gains less US-source capital losses. It applies even to transactions made while you were outside the United States. Someone present that long is usually a US resident under the substantial presence test, so this rule mostly affects people whose days are excluded, such as some students.

When crypto gains are effectively connected income

Income effectively connected with a US trade or business is taxed differently. Publication 519 says it is taxed at graduated rates. These are the same rates that apply to U.S. citizens and residents, while income that is not effectively connected is taxed at a flat 30% or lower treaty rate. A nonresident running a trading business through a US office is in the first group; a person trading a personal account from abroad generally is not.

How is crypto classified in the first place?

As property. The IRS says that for U.S. tax purposes, digital assets are considered property, not currency. That is why the capital gain rules above apply to a sale or swap. For how the same rules work for a US taxpayer, see how crypto is taxed in the US.

Are You Actually a Nonresident? The Residency Tests

Everything above depends on being a nonresident alien for tax purposes. That is a tax test, not an immigration status, and a person on a visa can be a US tax resident.

The green card test

You are a resident for tax purposes if you are a lawful permanent resident of the United States at any time during the calendar year. A green card holder signs a W-9, not a W-8BEN.

The substantial presence test

Publication 519 sets out the day count: you must be physically present in the United States on at least 31 days during the current year and 183 days over the three-year period, counting all the days in the current year, one third of the days in the prior year and one sixth of the days in the year before that.

Days that do not count

Some days are excluded from the count. The IRS lists, among others, days in transit between two foreign places, days you cannot leave because of a medical condition that arose in the US, and days you are an exempt individual, a category Publication 519 applies to foreign government-related individuals, teachers and trainees, students and professional athletes who meet its conditions.

What if you moved to or from the US mid-year?

You may be a dual-status taxpayer, a resident for part of the year and a nonresident for the rest. Publication 519 says a person who gives up residence during the year and is not a resident on the last day must file Form 1040-NR, marked as a dual-status return, with a statement for the resident part of the year. Crypto sold during the resident period is reported as a US person; crypto sold after leaving follows the nonresident rules.

Staking and Other Crypto Income for Nonresidents

Income is where a nonresident account can create a US filing even when gains do not.

Is staking income on a US exchange taxed for a nonresident?

The IRS treats digital assets received from mining, staking and similar activities as digital asset transactions for the question on the return. For a nonresident, whether the reward is taxed in the US depends on its source and on whether it is effectively connected with a US business, under the general rules in Publication 519. Publication 519 does not address staking by name, so the analysis follows the general source rules, and a treaty can change the rate on some income. For the US-resident view, see our guide to how staking rewards are taxed.

Interest, yield and lending products

Crypto lending and yield products can pay amounts the exchange characterises as interest. These are the payments where your W-8BEN and any treaty claim in Part II do real work, because withholding at source is decided from the form on file.

Payment for services in crypto

Crypto received as pay is income, and the IRS includes payment for property or services among the digital asset receipts the return asks about. For a nonresident, Publication 519 says all wages and any other compensation for services performed in the United States are considered to be from sources in the United States, with narrow exceptions. Being paid in crypto rather than dollars does not move the source.

Filing Form 1040-NR With Crypto Activity

Many nonresidents with only exempt gains have nothing to file in the US. Those who do file use Form 1040-NR.

Do you answer the digital asset question on Form 1040-NR?

Yes. The 1040-NR instructions say that you must answer the digital asset question on Form 1040-NR whether or not you received a Form 1099-DA. The same instructions note that for 2025 a broker has the option to report basis on Form 1099-DA but is not required to.

Where do crypto gains go on Form 1040-NR?

Gains not effectively connected with a US business go on Schedule NEC. Publication 519 says to report your gains and losses from the sales or exchanges of capital assets that are not effectively connected with a trade or business in the United States on Schedule NEC (Form 1040-NR). Effectively connected gains are reported the way a US person reports them, on Form 8949 and Schedule D; see Form 8949 and Schedule D for crypto.

Can you file to recover tax withheld in error?

Yes. Where tax was withheld and you are entitled to a lower rate or an exemption, Form 1040-NR is how you claim it back. Publication 519 notes that in some treaty cases you must file Form 1040-NR to recover any overwithheld tax and to show you are entitled to the treaty exemption.

Records a Nonresident Crypto Investor Should Keep

A documented nonresident still needs records, for the home country return and for any US filing.

What to keep from the exchange

Keep a full transaction export for every year, the dates and amounts of every deposit and withdrawal, and a copy of each W-8BEN you signed with its date. The IRS lists the information needed to calculate a digital asset gain or loss: the type of digital asset, the date and time of the transaction, the number of units, the fair market value in US dollars at the time, and the basis of what was sold.

How long to keep records

For US purposes the IRS says to keep records for 3 years in the ordinary case, with longer periods in specific situations. Crypto records support basis for as long as you hold the asset, so in practice they are kept from purchase until at least three years after the return that reports the sale.

Why the exchange's export is not enough on its own

An exchange export shows what happened on that exchange. It does not show where coins came from before they were deposited, so the purchase cost of anything transferred in is missing. That gap is the most common reason a cross-border crypto history needs reconciling before a home-country return can be filed. Transfers in and out of wallets you control are covered in our guide to what non-custodial and no-KYC platforms report.

Your Home Country Still Taxes Your Crypto

US exemption is not tax freedom. The US rules above only decide what the United States charges. Your country of residence applies its own rules to the same gains, and a US account does not move the gains outside them.

Where do you report the gains instead?

In the country where you are resident for tax purposes, under its rules. Our country guides cover the UK, Canada and South Africa, and the list of crypto tax-free countries shows which jurisdictions do not tax gains at all.

Does a treaty stop double tax on crypto gains?

For most nonresidents there is no US tax on the gains to double up with. Where US tax does apply, such as on income, the treaty between the US and your country decides the rate and which country gives relief. The IRS notes that if there is no treaty, you pay US tax on that income in the same way as any other nonresident.

When to get help

If your history spans a move to or from the US, several exchanges, or wallets and DeFi activity the exchange cannot see, the numbers need to be rebuilt before either country's return is filed. That reconciliation is what our crypto tax accounting service does, and the report goes to the adviser who files your return.
