Banking Guide

Open a Mercury Bank Account With Your EIN (2026)

Mercury is the most popular online business bank for non-resident LLC owners. $0 monthly fee, no minimum balance, fully online application. Your EIN is the first requirement.

Mercury is the most popular online business bank for non-resident LLC owners. You can open a Mercury account from anywhere in the world using your US company and EIN — no SSN, no US address, and no in-person visit required. Mercury charges $0 monthly fees and has no minimum balance. The one requirement you cannot skip is an EIN. Apply for your EIN at ein.so ($49) before you start the Mercury application.

Mercury serves more than 200,000 startups and online businesses and is the default banking choice for non-US founders who run a US LLC. The account is fully digital, supports USD wires and ACH, issues virtual and physical debit cards, and connects to Stripe, PayPal, and accounting tools. This guide explains exactly how to open a Mercury account with your EIN, which documents you need, how long approval takes, and the most common reasons applications get rejected.

Eligibility

Can a Non-Resident Open a Mercury Account With an EIN?

Yes. A non-resident can open a Mercury account with an EIN, a registered US LLC or C-corporation, and a passport. Mercury does not require an SSN, a US address for the owner, or a US visit. The company must be the account holder, not the individual.

Mercury onboards founders from most countries. As of 2026, Mercury does not open accounts for businesses based in or owned by residents of a short list of sanctioned and high-risk jurisdictions. Mercury also does not serve sole proprietors or trusts — you need a formal US entity (LLC or corporation) with its own EIN. If you do not yet have a US company, form the LLC first, then get the EIN, then apply to Mercury.

Who Mercury accepts

  • Owners of US LLCs and C-corporations registered in any state
  • Non-US residents from 200+ countries (limited exceptions)
  • Single-member and multi-member LLCs
  • Tech startups, SaaS companies, e-commerce sellers, agencies, and freelancer LLCs

Requirements

What Do You Need to Open a Mercury Account?

You need 5 items to open a Mercury account as a non-resident. Every item is verified online during the application, so prepare all documents before you start.

#RequirementWhere it comes from
1EIN and EIN confirmation letterIRS — via ein.so for $49
2Articles of Organization (LLC) or incorporationYour state's Secretary of State
3Operating AgreementYour LLC formation documents
4Passport for each 25%+ ownerYour home country
5Proof of address and business detailsUtility bill, lease, or bank statement

Your EIN is the gatekeeping document. Mercury matches your 9-digit EIN and your legal business name against IRS records during onboarding. If the name on your EIN confirmation letter does not match your formation documents exactly, Mercury holds the application. Apply for a Letter 147C if you have lost your original CP 575 confirmation.

Step by Step

How Do You Open a Mercury Account With Your EIN?

Opening a Mercury account takes 6 steps and 1 to 3 business days after your documents are ready.

1

Get Your EIN First

Apply for your EIN before anything else. Non-residents cannot use the IRS online tool and must file Form SS-4 by fax. ein.so files it for you and delivers the EIN in 7 to 14 business days. This is the slowest step, so start here.
2

Gather Your Documents

Collect your EIN confirmation letter, Articles of Organization, Operating Agreement, and a passport for every owner with 25% or more ownership. Save them as clear PDF or image files.
3

Start the Mercury Application

Go to mercury.com and click 'Open Account'. Enter your business legal name exactly as it appears on your EIN letter, your EIN, your state of formation, and your industry.
4

Add Owner and Business Details

Enter personal details and upload a passport for each beneficial owner. Describe what your business does, your expected monthly transaction volume, and your main customer countries. Be specific and honest — vague answers trigger review.
5

Submit for Compliance Review

Mercury runs Know Your Customer (KYC) and Know Your Business (KYB) checks against your EIN and documents. Most applications clear in 1 to 3 business days. You may receive a follow-up email requesting one extra document.
6

Fund and Activate the Account

After approval, log in, order your debit cards, and fund the account by wire or ACH. There is no minimum deposit, so you can transfer any amount to activate transactions.

Cost

How Much Does a Mercury Account Cost?

A Mercury checking account costs $0 to open and $0 per month. Mercury earns revenue from interchange and treasury products, so standard business checking carries no maintenance fee and no minimum balance.

ItemCost
Account opening$0
Monthly maintenance fee$0
Minimum balance$0
Domestic ACH and incoming wires$0
Outgoing USD wires$0
International (SWIFT) wiresVaries by destination
Mercury Plus / Pro paid plansFrom $35/month (optional)

The only EIN-related cost is the EIN itself. The IRS charges $0 for an EIN, and ein.so charges $49 (Standard) or $97 (Express) to prepare and file Form SS-4 for non-residents who cannot apply online. See the full EIN cost breakdown.

Avoid Rejection

Why Mercury Rejects Applications (and How to Avoid It)

Mercury rejects applications mainly for document mismatches and unclear business descriptions. Most rejections are preventable.

Top 5 reasons Mercury holds or rejects an application

  1. EIN name mismatch. The business name on your EIN letter must match your Articles of Organization exactly, including punctuation.
  2. Brand-new EIN. A newly issued EIN can take up to 2 weeks to appear in IRS records. Wait if Mercury cannot verify it.
  3. Vague business description. "Consulting" is too broad. Describe your product, customers, and revenue model.
  4. High-risk industry or country. Crypto, gambling, and certain jurisdictions face extra review or denial.
  5. Missing beneficial owner. Every owner with 25% or more must be listed with a passport.

If Mercury declines your application, you can reapply after fixing the issue, or open a Relay account instead. Both accept non-resident LLC owners with an EIN.

Benefits

Why Does Your US Business Need a Mercury Account?

A US business bank account separates your company's money from your personal funds, which is the legal foundation of LLC liability protection. Mercury gives a non-resident founder a real US account without a US visit.

Mercury provides 6 concrete benefits for non-resident founders:

  • Liability protection — Mixing personal and business money can pierce the corporate veil. A dedicated business account keeps your LLC's limited liability intact.
  • USD payments — Receive payouts from Stripe, PayPal, Amazon, and US clients directly in US dollars.
  • Virtual and physical cards — Issue virtual debit cards for ad spend, software, and team members.
  • Free wires and ACH — Send and receive domestic wires and ACH at no cost.
  • Treasury and API — Earn yield on idle cash and automate payments through Mercury's API.
  • Clean bookkeeping — Export transactions to QuickBooks or Xero for Form 5472 and federal tax filing.

Without a US business account, your LLC cannot accept card payments, pay US vendors, or build a financial record. Opening one is the first operational step after formation.

EIN First

Why Do You Need an EIN Before Opening Mercury?

You need an EIN before opening Mercury because the account belongs to your business, and the IRS identifies your business by its EIN. Mercury cannot open or verify a business account without one.

Your EIN is your business's 9-digit federal tax ID, issued by the IRS in the format XX-XXXXXXX. Mercury uses it for 3 reasons: to confirm your LLC is a registered taxpayer, to file tax forms tied to your account, and to run anti-money-laundering checks. See what an EIN is and why every LLC needs one.

US residents get an EIN online in minutes. Non-residents are blocked from the IRS online tool and must file Form SS-4 by fax, which takes longer and is easy to fill out incorrectly. A rejected SS-4 delays your bank account by weeks. ein.so prepares and files the form correctly for $49, so your EIN is ready before you start the Mercury application. Learn how to get an EIN without an SSN.

After Approval

What Can You Do After Your Mercury Account Is Open?

Once your Mercury account is open, your EIN and US bank account unlock the full US business stack. The account is the hub that every payment platform connects to.

PlatformWhat your Mercury account enables
StripeReceive card payment payouts in USD
PayPalLink a US business account for withdrawals
AmazonReceive FBA disbursements to a US account
ShopifyConnect Shopify Payments payouts
Business creditBuild a US business credit profile over time

You can also pay US contractors, subscribe to US software, hold USD reserves, and issue cards to your team. For the complete list, see what you can do with an EIN.

Compliance

Tax and Compliance Notes for Foreign-Owned LLCs

A foreign-owned US LLC with a Mercury account has 3 federal compliance obligations. Opening the bank account does not create new taxes, but it does create records the IRS expects you to report.

1

Form 5472 + Pro-Forma 1120

A foreign-owned single-member LLC must file Form 5472 with a pro-forma Form 1120 every year. The penalty for not filing is $25,000. Your Mercury transaction history documents the reportable transactions.
2

BOI Report to FinCEN

Most LLCs must report their beneficial owners to FinCEN. Review the BOI filing rules and deadlines to avoid penalties.
3

Form 1099-K From Processors

Stripe and PayPal issue Form 1099-K tied to your EIN once you cross reporting thresholds. Keep your Mercury records aligned with these forms.

This is general information, not tax advice. Confirm your specific filing requirements with a US tax professional.

Mistakes to Avoid

5 Mistakes to Avoid When Opening a Mercury Account

Most delays come from preventable mistakes made before or during the application. Avoid these 5 to get approved on the first try.

  1. Applying before your EIN is in IRS records. A brand-new EIN can take up to 2 weeks to propagate. Wait if Mercury cannot verify it.
  2. Using a name that does not match your EIN letter. Enter your legal business name exactly as printed on your EIN confirmation letter.
  3. Choosing the wrong entity. Mercury does not accept sole proprietors or trusts. Form an LLC or C-corporation first.
  4. Writing a vague business description. Explain your product, customers, and revenue model in detail.
  5. Skipping a beneficial owner. List every owner with 25% or more and upload a passport for each.

Fix these before you apply and your account typically opens within 1 to 3 business days.

Next Steps

Get Your EIN, Then Open Your Mercury Account

The EIN is the one requirement that takes time, so get it first. Non-residents cannot use the IRS online application and must file Form SS-4 by fax — a process where ein.so handles the paperwork, files with the IRS, and delivers your EIN by email for $49.
