Opening a business bank account used to mean a branch visit and a stack of paperwork. With Mercury, the sign-up process is fully online and usually takes just a few minutes. This step-by-step guide walks you through exactly what you need, how approval works, and how to unlock the current up to $375 cash bonus.
🚀 Open Mercury & Get Up to $375
Sign up in minutes and unlock $275 for a $10K deposit plus $100 for $10K of IO card spend — both within 90 days.
What You Need Before You Start
Mercury is business-only banking, so you will need:
- A registered US business entity — LLC, C-Corp, or S-Corp.
- Your EIN (Employer Identification Number) from the IRS.
- Formation documents (e.g., Articles of Organization or Incorporation).
- A government-issued ID for the primary owner.
- Basic details about what your business does.
Good news for international founders: Mercury supports non-US residents who own a US company, which is one reason it is so popular with global startups.

Common Sign-Up Questions
How long does approval take?
Often within a day. More complex businesses may take a little longer if Mercury requests additional documents.
Is there a minimum deposit to open?
No minimum to open, and no monthly fees. You only need the $10K deposit if you want the $275 bonus.
Can a sole proprietor sign up?
Mercury requires a registered entity (LLC or corporation). If you are a sole proprietor, forming an LLC first is the usual path.
