Best Bank for US LLC Owner Living in Portugal: 2026 Comparison

If you run a US LLC and live in Portugal, your best business banking option in 2026 is Relay for FDIC-insured US banking, or Wise for the easiest approval and multi-currency handling. Airwallex and Lili are viable backups, but each comes with trade-offs. Revolut is effectively off the table unless you can prove a physical US presence. And no, a Portuguese bank won’t solve this: your LLC needs a US-based account to stay compliant and functional.

Key facts before you choose:

• Wise is the easiest account to get approved for, followed by Relay. (LLCUniversity)
• Wise is an Electronic Money Institution, not a bank. Your money is safeguarded, not FDIC-insured. (Wise)
• Relay provides FDIC insurance through its partner banks. (LLCUniversity)
• Readers report success opening accounts with Airwallex and Lili as non-resident LLC owners. (LLCUniversity)
• The Portuguese tax authority treats US LLC income allocable to a resident as capital income, taxed at a flat 28% (with an option to include it in global income). (GoalSeek)
• Banks reject non-resident LLC applications for three main reasons: no SSN/ITIN, no verifiable US address, or a compliance flag on your country of residence. (Prodezk)

Why a US Business Account Matters (and Why Portuguese Banks Don’t Fit)

Your US LLC is a US entity. To accept payments, pay US vendors, and file taxes, it needs a US-based business bank account. A Portuguese personal account won’t cut it: mixing business and personal funds is a compliance headache, and Portuguese banks aren’t set up to service foreign LLCs.

Portuguese banks open business accounts for Portuguese-registered companies: Lda, Unipessoal, or a branch. A US LLC is none of those. Even if you manage to open a Portuguese personal account as a resident, using it for LLC income creates messy tax reporting and potential currency conversion losses. Stick with a US business account.

The Options: US Fintechs That Accept Non-Resident LLCs

Four providers stand out in 2026: Wise, Relay, Airwallex, and Lili. Each has a distinct profile. Here’s how they compare side by side.

Wise

Pros: Approval is fast and straightforward. You get multi-currency accounts, low conversion fees, and an interface built for international businesses. If you need to send and receive money in euros, dollars, and other currencies, Wise is the path of least resistance.

Cons: It’s not a bank. Wise is an Electronic Money Institution. Your funds are safeguarded, held in separate bank accounts, but they’re not FDIC-insured. For most day-to-day operations, the risk is minimal. But if you hold large balances, this matters.

Relay

Pros: A real US business checking account with FDIC insurance through its partner banks. You get features like multiple accounts, team access, and integrations with accounting software. It’s the closest thing to a traditional business bank account that still accepts non-resident LLCs.

Cons: Relay is stricter about documentation. You’ll need a verifiable US address: a registered agent address alone often isn’t enough. Be prepared to show proof of business activity, like invoices or a website. Approval takes longer than Wise, but once you’re in, you have a solid banking relationship.

Airwallex

Pros: Several readers report success opening accounts with Airwallex. It offers multi-currency wallets and competitive FX rates. If Wise and Relay both say no, Airwallex is worth a try.

Cons: It’s less transparent about FDIC insurance. The platform is more geared toward enterprise users, and support for solo non-resident LLC owners can be inconsistent. Don’t expect the same smooth onboarding as Wise.

Lili

Pros: A US-based neobank that has accepted non-resident LLC applications. The app is simple, and it’s designed for freelancers and small businesses. If you want a no-frills checking account with basic features, Lili can work.

Cons: Lili’s requirements can change overnight. Some users report sudden requests for SSN or ITIN. Its FDIC insurance status is also unclear: verify directly before depositing large sums.

Why Revolut and Mercury Aren’t on the List

Revolut requires US companies to demonstrate a “real, physical presence in the US.” As a Portugal-based owner, you’re unlikely to meet that bar. Mercury, once popular with non-resident founders, has tightened its onboarding dramatically. We could not confirm a single recent success story for a non-resident LLC owner with no US ties. Don’t waste an application on either.

Before You Apply: The 7-Step Document Checklist

Gather these before you start any application. Missing one item is the fastest route to rejection.

1. Form your US LLC. If you haven’t already, file with a state like Wyoming or Delaware. You’ll need the Articles of Organization.
2. Obtain an EIN from the IRS. This is your LLC’s tax ID. Apply online if you have an SSN/ITIN; otherwise, use a service or fax Form SS-4.
3. Get a Portuguese NIF (Número de Identificação Fiscal). While not required by US banks, you’ll need it for Portuguese tax reporting. No Portuguese bank will open any account without one, and it’s essential for your tax filings. (molportugal.com)
4. Prepare proof of identity. A valid passport. Some banks may ask for a notarized copy.
5. Prepare proof of address. A utility bill, bank statement, or lease agreement showing your Portuguese address. This must match the address on your application.
6. LLC formation documents. Operating Agreement, Articles of Organization, and sometimes a Certificate of Good Standing.
7. Evidence of business activity. A website, invoices, contracts, or a business plan. Banks want to see that your LLC is a real operating business, not a shell.

The Rejection Trap: Why Banks Say No and How to Avoid It

Banks reject non-resident LLC applications for three concrete reasons. (Prodezk)

No SSN or ITIN. Most US banks run identity checks that require a Social Security Number or Individual Taxpayer Identification Number. As a non-resident, you likely have neither. Fintechs like Wise and Relay have built workarounds, but traditional banks will reject you outright.

No verifiable US address. A PO box or registered agent address won’t pass. Banks want a physical address they can confirm: a virtual office with a lease agreement, or a friend’s address with a utility bill in your LLC’s name. This is the single most common reason for rejection.

Country-risk compliance flag. If your country of residence appears on a high-risk list under US anti-money-laundering rules, banks may refuse to onboard you. Portugal is not typically flagged, but if you’ve recently moved from a higher-risk country, that history can follow you.

In 2025, regulators stepped up requirements further. Banks now demand clear beneficial-owner data, stricter KYC checks, and often video verification. (FilingExpress) Your documents must look original, not scanned copies of scans. Be ready to explain your business model in a short video call.

How to improve your odds:

• Use a virtual office service that provides a real physical address and a lease document.
• Have your passport notarized or apostilled if the bank requests certified copies.
• Apply to multiple providers simultaneously: Wise and Relay are the safest bets, with Airwallex and Lili as backups.
• Keep your business story consistent across all documents. A mismatch between your website, operating agreement, and application will trigger a manual review.

Portuguese Tax Implications: The 28% Reality

Portugal taxes residents on worldwide income. Even though the US treats a single-member LLC as a disregarded entity, Portugal does not import that treatment. The Autoridade Tributária (AT) has consistently ruled that US transparency rules cannot be applied by analogy. (GoalSeek)

Instead, the AT qualifies LLC income attributable to a Portuguese resident as capital income (Category E), taxed at a flat 28%. You can opt for englobamento to include it in your global income and potentially benefit from progressive rates if your total income is low. But for most self-employed LLC owners, the flat 28% is the starting point.

This is not tax advice. If you hold NHR status, the interaction with LLC income is complex and fact-specific. Speak to a Portuguese tax advisor before relying on any general rate.

Stripe and Payment Processing: Getting Paid from Portugal

Once you have a US business bank account, you can accept payments through Stripe. Stripe verifies your LLC and EIN against US records, not your personal nationality. As a non-US resident, you’ll need to file Form W-8BEN-E to confirm your foreign owner status. (RocketWave)

This setup works seamlessly: US LLC → US bank account → Stripe. Your customers pay in dollars, and you transfer funds to your US account. From there, you can use Wise or another service to convert and send money to your Portuguese personal account as needed.

How to Choose: Decision Tree

Answer these questions in order. The path will point you to the right provider.

• Do you need FDIC insurance and a real US bank account?
• Yes → Relay. It’s the only option that combines FDIC insurance with a high approval rate for non-resident LLCs.
• No, I’m comfortable with an EMI → Next question.

• Is multi-currency capability and low-cost FX your top priority?
• Yes → Wise. Approval is fast, fees are low, and you can hold 50+ currencies.
• No, I just need a basic US checking account → Next question.

• Have you been rejected by Wise and Relay?
• Yes → Try Airwallex or Lili. Success rates are lower, but they’re worth a shot before giving up.
• No → Start with Wise or Relay. Don’t overcomplicate it.

The Verdict: Which Bank Wins for Whom

For most US LLC owners living in Portugal, Relay is the strongest choice. It gives you a real US bank account with FDIC insurance, multiple account features, and a track record of accepting non-resident applicants. The documentation burden is higher, but the peace of mind is worth it.

If you want the smoothest onboarding and don’t mind the lack of FDIC insurance, go with Wise. You’ll be up and running in days, and the multi-currency features will save you money on every cross-border transfer.

Airwallex and Lili are fallbacks. Use them only if the first two reject you, and be prepared for a bumpier ride.

Avoid Revolut and Mercury. Their requirements have become too strict for a Portugal-based owner with no US physical presence.

Whatever you choose, keep your Portuguese NIF handy, file your LLC income correctly at 28%, and never mix business and personal accounts. A clean setup now saves you a frozen account and a tax headache later.

FAQ

Can I open a Portuguese bank account for my US LLC? No. Portuguese banks open business accounts for Portuguese-registered companies. A US LLC is a foreign entity and won’t qualify. You need a US-based business account.

Do I need a US address to open a US business bank account? Most providers require a verifiable US address. A registered agent address alone may be rejected. A virtual office with a physical address and lease agreement improves your odds.

How long does it take to get approved for a US business account from Portugal? Wise often approves within days. Relay and others can take 1–3 weeks, mostly due to document verification. Having all your documents ready in advance cuts the time significantly.

Is Wise safe without FDIC insurance? Wise is an Electronic Money Institution, not a bank. Customer funds are safeguarded in separate bank accounts, but they are not FDIC-insured. For most day-to-day business, the risk is low. If you hold large balances, consider Relay for the insurance protection.

What about Mercury? I’ve heard it works for non-residents. Mercury has tightened its onboarding significantly. We could not confirm any recent success stories for non-resident LLC owners without a US presence. It’s not a reliable option in 2026.

Do I need an ITIN to open a US business bank account? Not for the fintechs listed here. Wise, Relay, Airwallex, and Lili all accept your foreign passport and LLC documents without an ITIN. Traditional banks will almost always require one.
