If you are a U.S. tax nonresident and your Fidelity cash is in the FDIC program‑bank sweep with no U.S.‑business connection, you owe no federal withholding tax and file no annual IRS form just for that interest—you give Fidelity Form W‑8BEN instead.
“I am a non-resident with an ITIN. Do I need to pay withholding tax on the interest earned in my US Fidelity bank account, and if so, what form do I need to submit to the IRS annually?”
Summary
Your ITIN does not by itself make the interest taxable. Once you identify whether your Fidelity cash is a program‑bank deposit or a money‑market fund, the correct form path is clear.
Your answer turns on what Fidelity actually holds as your cash and whether the income is connected with a U.S. business.
If your cash is in Fidelity’s and the interest is not , IRC 871(i)(1)–(2) imposes no federal tax and 26 CFR 1.1441-1(b)(4)(ii) exempts it from withholding. Give Fidelity Form W-8BEN to certify foreign status; do not send that form to the IRS, and do not file Form 1040-NR solely for this exempt interest [1], [2], [3], [4].
A money-market fund is not a bank account, so its payment is not automatically protected as deposit interest. Under IRC 871(k)(1), any portion the fund reports in writing as an is exempt; another U.S.-source fund dividend that is is generally subject to 30% withholding or a lower treaty rate. Form W-8BEN goes to Fidelity, Fidelity reports the income and withholding on Form 1042-S, and you need Form 1040-NR only if tax was not fully withheld, you seek a refund, or another filing trigger applies [5], [6], [7], [4].
If the interest is , IRC 871(i)’s exclusion does not apply. Give Fidelity Form W-8ECI—not W-8BEN for that income—and file Form 1040-NR annually; the Form W-8ECI itself says anyone submitting it must file an annual U.S. income-tax return for the claimed business-connected income [1], [8], [4].
Your country of tax residence is also needed only to determine any treaty rate and whether Fidelity must issue an information form; it does not remove the federal deposit-interest exemption in IRC 871(i).

Next steps
These steps identify the income correctly, prevent unnecessary withholding, and show whether you have any annual filing duty.
First
Identify your Fidelity cash position
Determine whether the position is “FDIC-Insured Deposit Sweep” or “SPAXX – Fidelity Government Money Market Fund.” Fidelity expressly offers those as different core choices: the sweep places cash in interest-bearing program-bank accounts, while SPAXX is a money-market fund and not a bank account [5].
Requirements
Before income is paid or when Fidelity requests it
Submit Form W-8BEN to Fidelity
Use Fidelity’s foreign-status certification page at https://www.fidelity.com/customer-service/how-to-update-foreign-status and select W-8BEN for an individual. Submit it to Fidelity, not the IRS. It normally remains valid until December 31 of the third calendar year after signing unless a change makes it incorrect; after such a change, notify Fidelity and submit a replacement within 30 days [3].
Requirements
For the deposit-sweep branch
Treat qualifying deposit interest as exempt
Do not pay federal NRA withholding or file Form 1040-NR solely for this interest. If Fidelity issues Form 1042-S with income code 29 and chapter 3 exemption code 02, keep it as the payer’s information statement; you do not submit Form 1042-S yourself. If Fidelity withheld tax from this exempt interest, use Form 1040-NR to claim the available refund [1], [2], [10], [4].
Requirements
For SPAXX or another fund
Apply the money-market distribution rules
The part reported by the fund as an is exempt under IRC 871(k). Other U.S.-source is generally withheld at 30% or a lower treaty rate. If you are not engaged in a U.S. trade or business and withholding fully satisfied the tax, the 1040‑NR instructions say no return is required for that income alone; file Form 1040‑NR if withholding was insufficient or you are claiming a refund [6], [7], [4].
Requirements
Only for the U.S.-business branch
Use W-8ECI and file Form 1040-NR if the interest is ECI
Give Form W-8ECI to Fidelity and report the income annually on Form 1040-NR. For a calendar-year return, the general deadline is April 15 if you received employee wages subject to U.S. withholding, otherwise June 15 (for 2025, April 15 or June 15, 2026) [8], [11].

You are not the first to go through this. Here is how it went for others who asked the same thing.
Legal sources
This answer rests on Internal Revenue Code section 871, Treasury regulations, IRS form instructions and guidance, and Fidelity’s own account disclosures.
26 USC 871(i)
Qualifying U.S. deposit interest is excluded from an NRA’s federal tax when it is not connected with a U.S. trade or business.
871(i)(1)–(2)(A)
No tax shall be imposed under paragraph (1)(A) or (1)(C) of subsection (a) on any amount described in paragraph (2). Interest on deposits, if such interest is not effectively connected with the conduct of a trade or business within the United States.
26 CFR 1.1441-1
The regulation exempts qualifying U.S. bank-deposit interest from NRA withholding while allowing documentation for reporting and backup-withholding purposes.
1.1441-1(b)(4)(ii)
Bank deposit interest and similar types of deposit interest (including original issue discount) described in section 871(i)(2)(A) or 881(d) that are from sources within the United States are exempt from withholding under section 1441(a). See section 1441(c)(10). Documentation establishing foreign status is not required for purposes of this withholding exemption but may have to be furnished for purposes of the information reporting provisions of section 6049 and backup withholding under section 3406.
Instructions for Form W-8BEN (Rev. October 2021)
W‑8BEN is given to Fidelity, normally lasts three succeeding calendar years, and must be replaced promptly after an invalidating change.
pages 3–4, Giving Form W-8BEN; Expiration; Change in circumstances
Do not send Form W-8BEN to the IRS. Instead, give it to the person who is requesting it from you. Generally, a Form W-8BEN will remain in effect for purposes of establishing foreign status for a period starting on the date the form is signed and ending on the last day of the third succeeding calendar year, unless a change in circumstances makes any information on the form incorrect. If a change in circumstances makes any information on the Form W-8BEN you have submitted 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.
Instructions for Form 1040-NR (2025)
1040‑NR is required for non‑business U.S. income only when withholding did not fully satisfy the tax; qualifying bank interest is excluded from taxable interest.
pages 7–8 and 19, Filing Requirements; Simplified Procedure; Line 2b
You must also file Form 1040-NR if you are a nonresident alien not engaged in a trade or business in the United States during 2025 and you have U.S. source income that is not effectively connected with the conduct of a U.S. trade or business on which the tax was not fully satisfied by the withholding of tax at the source. Don’t include on line 2b interest from a U.S. bank, savings and loan association, credit union, or similar institution (or from certain deposits with U.S. insurance companies) that is exempt from tax under a tax treaty or under section 871(i) because the interest isn’t effectively connected with a U.S. trade or business. You’re filing Form 1040-NR solely to claim a refund of U.S. tax withheld at the source under chapter 3 or tax withheld under chapter 4 (FATCA).
Fidelity Cash Management Account disclosure
Fidelity confirms its Cash Management Account is a brokerage account and distinguishes its program‑bank sweep from a money‑market fund.
Cash Management Account details and FAQs
The Fidelity Cash Management Account is not a bank account. It is a brokerage account that allows you to spend, save, and invest. The FDIC-insured Deposit Sweep program option sweeps your uninvested cash into an FDIC-insured interest-bearing account at one or more program banks.
26 USC 871(k)(1)
A fund distribution is exempt as an interest‑related dividend only to the extent the regulated investment company reports it that way.
871(k)(1)(A), (C)(i)
Except as provided in subparagraph (B), no tax shall be imposed under paragraph (1)(A) of subsection (a) on any interest-related dividend received from a regulated investment company which meets the requirements of section 852(a) for the taxable year with respect to which the dividend is paid. Except as provided in clause (ii), an interest related dividend is any dividend, or part thereof, which is reported by the company as an interest related dividend in written statements furnished to its shareholders.
IRS Taxation of Nonresident Aliens
Ordinary non‑business U.S.‑source FDAP is generally 30% or a treaty rate, while ECI goes on Form 1040‑NR.
FDAP income; Effectively Connected Income
FDAP income is taxed at a flat 30 percent (or lower treaty rate, if qualify) and no deductions are allowed against such income. Effectively Connected Income should be reported on page one of Form 1040-NR, U.S. Nonresident Alien Income Tax Return.
Form W-8ECI (Rev. October 2021)
W‑8ECI goes to Fidelity and creates an annual U.S. return obligation for the income claimed as ECI.
page 1
Give this form to the withholding agent or payer. Note: Persons submitting this form must file an annual U.S. income tax return to report income claimed to be effectively connected with a U.S. trade or business.
IRS ITIN Guidance
Tax residency depends on statutory tests, not on having an ITIN.
Determining tax residency; What an ITIN is used for
An ITIN is issued by the IRS for federal tax purposes only. Nonresident alien – If you don’t meet either the green card or substantial presence test for resident alien status.
Instructions for Form 1042-S (2026)
Withholding agents may need to report exempt deposit interest on Form 1042‑S even though no chapter 3 tax is withheld.
Amounts Subject to Reporting on Form 1042-S—Interest on deposits paid to certain nonresident aliens
Withholding agents must report certain interest described in section 871(i)(2)(A) aggregating $10 or more paid with respect to a deposit maintained at an office within the United States if such interest is paid to a nonresident alien individual who is a resident of a country identified in Rev. Proc. 2024-42, 2024-52 I.R.B. 1433, available at IRS.gov/irb/2024-52_IRB (or any superseding revenue procedure that is effective as of January 1, 2026). A payer may elect to report interest described above paid to any nonresident alien individual by reporting all such interest. When completing Form 1042-S, use income code 29 in box 1 and exemption code 02 in box 3a for chapter 3 purposes, and the applicable chapter 4 exemption code in box 4a (see the instructions for boxes 3a and 4a, later).
