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.
| Feature | Mercury | Novo |
|---|---|---|
| Standard checking | $0/month | $0/month |
| Sub-accounts | Yes | Limited |
| Corporate / debit cards | Yes | Debit card |
| Treasury / yield product | Yes (for larger balances) | No |
| Invoicing tools | Basic | Built-in |
| API access | Yes | Limited |
| Non-resident onboarding | Strong, remote | Limited |
| EIN required to open | Yes | Yes |
Both platforms hold deposits at FDIC-insured partner banks rather than acting as banks themselves. Verify the current partner bank and coverage on each site. Neither platform issues an EIN; you obtain that first. Non-residents get one without an SSN through ein.so.
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.

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.

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.
| Path | Cost | Speed | SSN Needed |
|---|---|---|---|
| IRS online tool | $0 | Instant | Yes (blocks non-residents) |
| DIY fax (Form SS-4) | $0 | 4-7 business days | No |
| ein.so Standard | $49 | 4-7 business days | No |
| ein.so Express | $97 | 2-3 business days | No |
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.
