Do I need a business bank account?

Legally you don't always need one — sole proprietors can use a personal account. But it's strongly advisable. Mixing personal and business funds creates tax problems, can destroy LLC liability protection (called 'piercing the corporate veil'), and makes bookkeeping far harder. If you've formed an LLC or corporation, most banks require a dedicated business account.

How much does a business checking account cost?

Many online banks offer free business checking with no monthly fees — Relay, Novo, and Mercury charge $0 for basic accounts. Traditional banks (Chase, Bank of America, Wells Fargo) charge $15–$35/month but often waive fees if you maintain a minimum balance ($1,500–$25,000 depending on account). Credit unions typically have lower or no fees.

What do I need to open a business bank account?

Most banks require: EIN (Employer Identification Number) from the IRS, business formation documents (Articles of Organization for LLC, Articles of Incorporation for corporations), business license if applicable, your personal ID (driver's license or passport), and an opening deposit (typically $0–$100 for online banks, $25–$100 for traditional banks). Sole proprietors can often use their Social Security Number instead of an EIN.

Which bank is best for small business?

For online-only convenience and no fees: Relay, Mercury, or Novo. For in-person branch access: Chase Business Complete Banking (extensive branch network) or a local credit union (lower fees, personal service). For high-interest savings alongside checking: a bank that offers both products. The 'best' bank depends on how you run your business — high cash deposits favor traditional banks; tech-forward businesses often prefer digital-first options.

Why a Separate Business Account Is Non-Negotiable for LLCs

An LLC’s core benefit is liability protection — the business’s debts are the business’s problem, not yours personally. But courts can “pierce the corporate veil” and hold owners personally liable if you treat the business like a personal piggy bank. The evidence they look for:

Personal and business expenses from the same account
Personal expenses paid by the business
No business records or bookkeeping
No business bank account at all

Beyond liability, mixing funds creates tax disasters. The IRS allows deductions for legitimate business expenses — but if you can’t distinguish business from personal spending in your records, you lose those deductions (or invite an audit).

The rule: Open a business account the same week you form your LLC or start generating business income.

What to Look for in a Business Checking Account

1. Monthly fees and waiver conditions. A $25/month fee is $300/year that comes right off your profit. Look for free accounts or accounts where the fee waiver requirement (minimum balance) is realistic for your business.

2. Transaction limits. Some accounts charge per-transaction fees after a monthly limit (e.g., 200 transactions free, then $0.40 each). High-volume businesses — retail, restaurants — need unlimited or high-limit accounts.

3. Cash deposit options. Online-only banks (Relay, Mercury) don’t accept cash deposits. If your business takes in significant cash, you need a bank with physical branches or ATM networks.

4. ACH transfers and wire fees. Domestic ACH transfers should be free. Wire fees vary widely — $15–$35 for outgoing wires at most banks; some online banks are cheaper.

5. Integration with accounting software. Most major banks connect to QuickBooks and Xero for automatic transaction categorization. Online-first banks (Relay, Mercury) often have especially strong integrations.

6. Credit card and loan relationship. If you plan to apply for a business loan or credit card, having your checking account at the same bank can help — lenders like seeing your cash flow directly.

How to Open a Business Bank Account

Step 1 — Get your EIN. Apply free at IRS.gov — you receive it immediately online. All businesses except sole proprietors running under their own name need one.

Step 2 — Gather business documents.

LLC: Articles of Organization + Operating Agreement
Corporation: Articles of Incorporation + Bylaws
Sole Proprietor: Personal ID + SSN (or EIN if you have one)
DBA: Fictitious business name certificate if operating under a trade name

Step 3 — Choose a bank and apply. Online banks: 10–20 minutes, online. Traditional banks: schedule an appointment or apply online.

Step 4 — Fund the account. Most accounts require an opening deposit. Online banks: often $0. Traditional banks: $25–$100 minimum.

Step 5 — Set up your bookkeeping connection. Connect to QuickBooks, Wave, or your accounting software so transactions sync automatically.

Business Savings: Where to Park Reserves

Your operating checking account should hold 1–3 months of operating expenses as a buffer. Anything beyond that earns more in a high-yield business savings account.

In 2026, the best business high-yield savings accounts are paying 4–5% APY — roughly what 12-month CDs pay, with full liquidity. Mercury’s Treasury account, Relay’s savings tiers, and several online banks offer competitive rates.

Tax reserve rule of thumb: If you pay quarterly estimated taxes, keep 25–30% of every revenue deposit in a separate savings bucket earmarked for taxes. Never let it get spent.
