Mercury and Novo are two of the most popular online business banking platforms for new US companies. Both target founders who want to skip branch visits and open an account online.

Head to Head

How Do Mercury and Novo Compare on Price and Features?

Mercury and Novo both advertise $0 monthly fees, no minimum balance, and free standard ACH transfers. Mercury adds treasury, multiple sub-accounts, and corporate cards aimed at funded startups. Novo focuses on invoicing and integrations for freelancers and service businesses. Confirm current fees on each provider's site, since add-on pricing changes.

The two platforms overlap on the basics and diverge on advanced features. Mercury targets companies that raise capital and hold larger balances. Novo targets owner-operators who invoice clients and want simple money management.

Non-Residents

Which Bank Is Better for Non-Resident LLC Owners, Mercury or Novo?

Mercury is better for non-resident LLC owners because it is built for remote, international onboarding and accepts founders from many countries without an SSN. Novo primarily serves US-based businesses, and non-residents report less consistent approval. Both require an EIN before you apply.

Mercury asks non-residents for an EIN, LLC formation documents, an operating agreement, a passport, and details about the business and its owners. It approves many applications within a few business days. Novo's eligibility leans toward US residents and US-based small businesses, so non-residents often choose Mercury or Relay instead.

Get Your EIN First

Neither bank opens an account without an EIN. Non-residents apply through ein.so for $49, using a passport number on Form SS-4 Line 7b. No SSN or ITIN is needed. See EIN for non-residents.

Prepare LLC Documents

Both banks want your Articles of Organization and an operating agreement from your formation state. Wyoming, Delaware, and New Mexico are common choices for non-resident LLCs.

Choose Mercury for Remote Access

Mercury supports remote opening for non-resident founders. Relay and Wise are strong alternatives. See best bank for non-resident LLC.

Confirm Novo Eligibility

Novo's strength is US-based freelancers and small businesses. Check current non-resident eligibility on Novo's site before applying so you do not waste an application.

The EIN is the constant in every path. It belongs to your LLC and works at any bank, so the bank choice never changes your EIN need. Start with EIN for a bank account.

Requirements

What Do You Need to Open a Mercury or Novo Account?

Mercury and Novo both require five items to open a US business bank account: an EIN, your LLC formation documents, an operating agreement, a government-issued ID, and your EIN confirmation letter. Non-residents also provide a passport and business ownership details. The EIN is the first and most time-sensitive item.

1

Form Your US LLC

Register your LLC through a registered agent in Wyoming, Delaware, New Mexico, or another state. This creates the legal entity that the bank account attaches to. You can do this fully online from outside the US.
2

Apply for Your EIN

File IRS Form SS-4 to get the EIN. Non-residents use the fax method, since the IRS online tool requires an SSN. ein.so faxes the SS-4 to the IRS at 855-215-1627 and returns your EIN by email for $49 (Standard) or $97 (Express).
3

Gather Supporting Documents

Collect your Articles of Organization, operating agreement, passport, and EIN confirmation (CP 575 or Letter 147C). Mercury and Novo both verify these during onboarding.
4

Apply to Mercury or Novo

Submit the bank application online with your documents. Mercury approves many non-resident applications in 1-3 business days. Novo opens eligible US-business accounts in 1-2 business days.

The EIN Step

How Do Non-Residents Get the EIN That Mercury and Novo Require?

Non-residents get an EIN by submitting IRS Form SS-4 by fax, using a passport number on Line 7b instead of an SSN. The IRS online EIN tool requires an SSN, so the fax method is the path for non-residents. The IRS charges $0 and issues most correct EINs in 4-7 business days.

Calling or faxing the IRS yourself works, but errors cause silent rejection and weeks of delay. International addresses are the most common rejection cause because they do not map cleanly to the SS-4 fields. ein.so prepares the SS-4 correctly, faxes it, and tracks the result.

PathCostSpeedSSN Needed
IRS online tool$0InstantYes (blocks non-residents)
DIY fax (Form SS-4)$04-7 business daysNo
ein.so Standard$494-7 business daysNo
ein.so Express$972-3 business daysNo

The EIN is free from the IRS; ein.so charges for preparing and filing the SS-4 correctly so a formatting error does not cost you weeks. See EIN cost and EIN processing time for the full breakdown. Non-residents start at EIN without an SSN.

After Opening

What Tax Filings Apply After You Open a Mercury or Novo Account?

A foreign-owned single-member US LLC must file IRS Form 5472 plus a pro-forma Form 1120 each year, even with no US income. The penalty for not filing is $25,000. Opening a Mercury or Novo account does not change this; the filing follows the LLC, not the bank.

Banking is one step. Federal compliance is another. Keep these obligations in view once the account is live.

Form 5472 + Pro-Forma 1120

Foreign-owned single-member LLCs file Form 5472 with a pro-forma Form 1120 annually. The penalty for missing it is $25,000. This is an information return, not automatically a tax bill.

BOI Report to FinCEN

Most US LLCs report beneficial ownership to FinCEN. Review the BOI filing rules so you do not miss the deadline. Filing at fincen.gov/boi is free.

State Annual Report

Your formation state may charge an annual report or franchise fee. Wyoming and New Mexico fees are low; confirm your state's current amount with your registered agent.

Confirm With a CPA

ein.so files the EIN and does not provide tax advice. Work with a US CPA familiar with non-resident LLCs to confirm your filing duties and any treaty positions.

Your EIN is the anchor for every filing above. It identifies the LLC to the IRS, to FinCEN, and to your bank. Keep your EIN confirmation letter stored safely; you reuse it for Mercury, Novo, payments, and taxes.
