Quick Answer
Yes — several online banks open high-yield savings accounts with an ITIN instead of a Social Security number: Marcus, American Express, Ally, SoFi, and Capital One 360 (Capital One's terms also require citizen or permanent-resident status). Top accounts paid 4.0%–4.2% APY as of August 2026, roughly 400 times the 0.01% rate of typical big-bank branch savings accounts.
Can I open a high-yield savings account with an ITIN?
Yes. Five online institutions confirm on their own sites or official channels that an ITIN works in place of an SSN: Marcus by Goldman Sachs, American Express National Bank, Ally Bank, SoFi, and Capital One 360. Each opens fully online — no branch visit — though every application also requires a U.S. residential address.
Federal identity rules are why this works. Banks must collect a taxpayer identification number under their Customer Identification Programs, and an ITIN issued by the IRS satisfies that requirement — the law never demands a Social Security number specifically. The four biggest branch banks (Chase, Bank of America, Citibank, and Wells Fargo) also accept an ITIN, but their standard savings accounts pay a fraction of online rates. See our guide to the best banks for ITIN holders for the in-person route.
What is a high-yield savings account?
A high-yield savings account is an FDIC-insured savings account paying far above the national average — around 4% APY at online banks in August 2026 versus the 0.38% national average reported by the FDIC. Online banks afford the higher rates because they skip branch overhead and pass the savings to depositors.
The rate is variable: it moves with the Federal Reserve's benchmark rate and can change at any time without notice. Compare current offers against the FDIC's monthly national rates table before opening, and expect every bank's number to drift over time. Everything else — deposits, withdrawals, insurance — works like the savings account at a branch bank.
Which banks offer high-yield savings accounts to ITIN holders?
Five institutions accept an ITIN and pay competitive yields: Marcus, American Express, Ally, SoFi, and Capital One 360. All five charge no monthly fee and require no minimum deposit. Capital One's account terms add one catch — its disclosures limit 360 accounts to U.S. citizens and lawful permanent residents.
| Institution | Accepts ITIN? | Min. deposit | Monthly fee | How to apply |
|---|---|---|---|---|
| Marcus by Goldman Sachs | Yes | $0 | None | Online — SSN or ITIN plus U.S. address |
| American Express National Bank | Yes | $0 | None | Online — "U.S. citizen or resident with SSN or ITIN" |
| Ally Bank | Yes | $0 | None | Online — SSN or ITIN accepted per Ally's FAQ |
| SoFi | Yes | $0 | None | Online — SSN or ITIN per SoFi support |
| Capital One 360 | Yes* | $0 | None | Online — ITIN accepted; terms require citizen or permanent resident |
| Synchrony Bank | Confirm | $0 | None | Application asks for a "Tax ID" — call to confirm ITIN before applying |
* Capital One's 360 Performance Savings disclosures accept an ITIN as the tax ID but separately require U.S. citizenship or lawful permanent residency, so read the eligibility terms before applying. Rates change weekly across all of these banks — as of August 2026 competitive online savings APYs ran roughly 3.5%–4.2%, and each bank posts its current rate on the product page linked above.
What documents do I need to open one?
Every application asks for four things: your nine-digit ITIN (the IRS CP565 assignment letter is the strongest proof), a government photo ID such as a foreign passport or matrícula consular, a U.S. residential address with proof like a utility bill, and a way to fund the account.
- Your ITIN. Enter the nine-digit number in the SSN/Tax ID field. Keep your CP565 letter handy in case verification asks for it — and if your ITIN has expired from disuse, renew it first.
- Government-issued photo ID. A current foreign passport works everywhere; some banks also take a matrícula consular or U.S. state ID.
- Proof of U.S. address. A lease, utility bill, or bank statement from the last 60–90 days. P.O. boxes are rejected — banks require a residential street address.
- Funding source. An existing U.S. checking account to link, or a mailed check or wire for the opening deposit. Some banks require the linked account to be at a U.S.-chartered bank.
How much interest will I actually earn?
At 4% APY, a $10,000 balance earns about $400 in a year, and $1,000 earns about $40. The same $10,000 in a 0.01% branch savings account earns $1. Over five years the gap tops $2,000, because high-yield interest compounds daily on an ever-larger balance.
| Balance | 0.01% APY (typical branch) | 0.38% APY (national average) | 4.00% APY (top online) |
|---|---|---|---|
| $1,000 | $0.10/yr | $3.80/yr | $40/yr |
| $5,000 | $0.50/yr | $19/yr | $200/yr |
| $10,000 | $1/yr | $38/yr | $400/yr |
Moving an idle balance is the single easiest raise most savers can give themselves — nothing about your income or spending has to change. If inflation is your worry, a high-yield rate near 4% also keeps cash roughly even with rising prices; see how ITIN holders can protect savings from inflation.
Do I pay taxes on savings interest with an ITIN?
Yes — savings interest is taxable income whether you have an SSN or an ITIN. Your bank sends Form 1099-INT when interest reaches $10 in a year, and you report it on your Form 1040 tax return. Certifying your ITIN on Form W-9 at account opening prevents 24% backup withholding.
The mechanics are simple. When you open the account you certify your taxpayer ID (the bank's application doubles as IRS Form W-9); each January the bank mails or posts Form 1099-INT; and the amount goes on your return as ordinary income — IRS Topic 403 covers the details. If total interest and dividends pass $1,500 you also attach Schedule B. Interest under $10 is still taxable even when no form arrives. Filing every year with your ITIN also keeps the number active — our guide to filing taxes with an ITIN walks through the process.
Is my money safe in a high-yield savings account?
Yes — deposits at FDIC-member banks are insured up to $250,000 per depositor, per bank, per ownership category, and every bank in this guide is an FDIC member. Credit union deposits carry the same $250,000 protection through the NCUA. Immigration status has no effect on deposit insurance coverage.
If a bank fails, the FDIC pays insured depositors regardless of how they identified themselves at account opening — an ITIN-opened account is protected exactly like an SSN-opened one. One caution: fintech apps that are not banks themselves hold your money at partner banks, and insurance only applies once funds actually reach the partner bank. When in doubt, open directly with an FDIC-member bank or an NCUA-insured credit union.
Should I choose a HYSA, a regular savings account, or a CD?
Choose a high-yield savings account for money you may need anytime: it paid around 4% APY in August 2026 with access in one or two business days. A regular branch account pays as little as 0.01% and mainly adds in-person convenience. A CD locks money away and charges an early-withdrawal penalty.
| Account type | Typical rate (Aug 2026) | Access to your money | Best for |
|---|---|---|---|
| High-yield savings | 3.5%–4.2% APY | Transfer out in 1–2 business days | Emergency funds and short-term goals |
| Regular branch savings | 0.01%–0.40% APY | Same-day at branch or ATM | Small balances needing in-person service |
| Certificate of deposit (CD) | Varies by term | Locked until maturity; penalty to exit early | Money untouched for 6 months to 5 years |
Money you won't touch for five or more years usually belongs in investments rather than any savings product — see opening a brokerage account with an ITIN for that next step.
What if an online bank rejects my ITIN application?
Rejection usually means the bank could not verify your identity or address electronically, not that ITINs are banned. Three fallbacks work: open in person at Chase, Bank of America, Citibank, or Wells Fargo; join an ITIN-friendly credit union; or try a second online bank, since each verifies identity differently.
Online banks verify applicants against credit-bureau header files, and a thin file — common when you're new to the U.S. financial system — can fail automated checks even with a valid ITIN. Branch openings sidestep this because a banker inspects your documents directly. Community institutions like Latino Community Credit Union welcome ITIN members, though their savings rates are far lower (0.15%–0.30% in 2026), so treat them as an on-ramp rather than a rate play. Our list of credit unions that accept ITINs covers the strongest options.
Can I keep my emergency fund in a high-yield savings account?
Yes — a high-yield savings account is the standard home for an emergency fund of 3–6 months of expenses. The money stays FDIC-insured and reachable within one or two business days while earning around 4% APY instead of sitting idle in checking. Keep it separate from everyday spending money.
The separation matters as much as the rate: a fund you can see growing in its own account is one you're less tempted to raid. Start with our emergency fund guide for ITIN holders for how much to save first, and the 25% savings rate framework for what comes after the fund is full.
Frequently Asked Questions
Can I open a high-yield savings account without a Social Security number?
Yes. Federal rules require banks to collect a taxpayer identification number, and an ITIN qualifies. Marcus, American Express, Ally, SoFi, and Capital One 360 all state through official channels that an ITIN works in place of an SSN on their savings applications.
Does opening a savings account with an ITIN affect my immigration status?
No. Opening a deposit account is legal regardless of immigration status, and banks are not immigration agencies. The account exists to hold your money and report interest to the IRS for tax purposes — the same as any other depositor's account.
Which bank pays the highest rate for ITIN holders?
It rotates — online savings rates change weekly, and the leader in any given month is rarely the leader six months later. As of August 2026 top accounts paid 4.0%–4.2% APY. Check each bank's current rate page and the FDIC's national rates table before choosing.
Do I owe taxes on interest if I earn less than $10?
Yes. All savings interest is taxable income even when the bank doesn't send a Form 1099-INT. The $10 threshold only controls whether the form is issued, not whether the income is reportable on your return.
Can I open a joint high-yield savings account if my spouse has an SSN?
Yes. Joint accounts work with one ITIN holder and one SSN holder — each owner provides their own taxpayer ID. A joint account also doubles FDIC coverage to $500,000 at one bank, since insurance applies per depositor.
