Yes, an S corporation can open a business checking account, and most banks will let you do it

An S corporation is a tax classification, not a legal entity type. Your business is still a corporation under state law—it just chose to be taxed as an S corp by the IRS. Banks care about your legal structure (corporation, LLC, sole proprietorship), not your tax choice. So if you formed a corporation and elected S corp status, you can open a business checking account the same way any other corporation does.

The bank will ask for your Employer Identification Number (EIN), your Articles of Incorporation, and a resolution from your board authorizing the account. Some banks may also want a copy of your IRS Form 2553, which is the election document you filed to become an S corp. This proves to the bank that you made the election and that it was accepted.

The main difference between an S corp account and other business accounts is not whether you can open one—it is that you need to keep the account separate from personal funds. The IRS expects S corps to maintain clear records, and commingling money makes that harder to prove if you are ever audited.

Key Takeaways

  • S corp status is a tax election, not a legal structure, so banks treat S corp accounts like any other corporate account.
  • You will need your EIN, Articles of Incorporation, and a board resolution to open the account.
  • Some banks ask to see Form 2553 (your S corp election) to confirm the election was filed and accepted.
  • The IRS requires S corps to keep business and personal money separate, so use the account only for business transactions.
  • Most major banks and many credit unions offer S corp business checking accounts with no special restrictions.

What documents the bank will ask for

When you walk into a bank or start an online application, have these items ready. The exact list varies by bank, but these are the standard ones.

Your Employer Identification Number (EIN) is the first thing they need. This is a nine-digit number the IRS issued when you filed Form SS-4. If you do not have one yet, you can get it the same day by calling the IRS at 1-800-829-4933 or by filing Form SS-4 online at irs.gov.

Your Articles of Incorporation prove you are a corporation under state law. This is the document you filed with your state's Secretary of State when you formed the business. The bank will want an official copy—usually a certified copy with the state seal. You can request this from your state's Secretary of State office, and it typically costs $5 to $25.

A board resolution authorizing the account is a one-page document signed by your board of directors (or by you, if you are the sole director) that says the corporation is opening a checking account and names who can sign checks. This is a formality, but banks require it to confirm that opening the account was a deliberate business decision, not something done without authority.

Some banks will also ask for a copy of Form 2553, which is the election form you filed with the IRS to become an S corp. This is optional—the bank is just confirming that your S corp election was real and accepted. If you do not have a copy, you can request one from the IRS using Form 4506-C, though this takes a few weeks.

How the application process works

Most banks let you start the application online or in person. The process is straightforward but slower than opening a personal account because the bank has to verify your business documents.

If you apply online, you will upload scans of your EIN letter, Articles of Incorporation, and board resolution. The bank will review these and may call you to confirm details. If everything checks out, they will send you account information and debit cards within a few business days. Some banks also require a video call to verify your identity.

If you apply in person, bring originals or certified copies of your documents. The banker will review them on the spot, take copies, and usually open the account the same day. You can start using the account within 24 hours.

The entire process usually takes 3 to 7 business days from application to first deposit. Online banks are often faster (1 to 3 days), while traditional banks with physical branches may take longer if they need to verify documents by mail.

Minimum balances and fees for S corp accounts

S corp accounts are treated like standard business checking accounts, so fees and minimums depend on the bank and the account tier you choose, not on your tax status.

Most banks charge a monthly maintenance fee ranging from $0 to $50, though many waive it if you keep a minimum balance (often $1,000 to $5,000) or set up direct deposit. Some banks charge per-check fees or per-transaction fees if you exceed a certain number of transactions per month. A few online banks offer S corp accounts with no monthly fee and no minimum balance.

Compare accounts at multiple banks before you choose. The cheapest option depends on how many checks you write, how many deposits you make, and whether you can meet the minimum balance. A bank that charges $25 per month but waives the fee at $2,500 may be cheaper than one with no monthly fee but $0.50 per check if you write 50 checks a month.

Why the IRS cares about separate accounts

The IRS does not require S corps to use a specific bank or account type. What it requires is that you keep business money separate from personal money. This is called piercing the corporate veil in reverse—if you mix funds, the IRS may treat the business and personal finances as one, which can cost you the liability protection your corporation provides.

A separate business checking account is the clearest way to prove you kept money separate. Every deposit and withdrawal is documented, and the bank statement becomes evidence that you treated the business as its own entity. If you are audited, the IRS will ask to see your business account statements. If you do not have them, or if they show personal expenses mixed in, the audit gets harder and more expensive.

You do not need a special account type—a regular business checking account works fine. The point is that it exists, it is in the business name, and you use it only for business transactions.

Common mistakes to avoid when opening an S corp account

The most common mistake is opening a personal account instead of a business account. Some owners do this to save on fees or because they think the tax status matters. It does not. A personal account in your name does not provide the liability protection your corporation offers, and it makes it much harder to prove to the IRS that you kept business and personal money separate.

Another mistake is not having your board resolution ready. Some owners think this is optional or do not know they need it. It is not optional—banks require it. If you do not have one, ask your accountant or a business attorney to draft one. It is a one-page document and costs very little.

A third mistake is not bringing certified copies of your Articles of Incorporation. Some banks will accept a photocopy, but many require a certified copy from the state. If you show up without one, the bank will ask you to get it and come back. Order it ahead of time from your state's Secretary of State office.

Finally, do not assume all banks offer S corp accounts. Most do, but some smaller banks or credit unions may not have the infrastructure to handle business accounts. Call ahead or check the bank's website before you apply.

Frequently Asked Questions

Do I need a separate account if I am the only owner of my S corp?

Yes. The IRS still requires you to keep business and personal money separate, even if you are a sole owner. A separate account is the clearest way to prove this separation. It also makes bookkeeping much easier and protects your personal liability protection if you are ever sued.

Can I use my personal checking account for my S corp?

Technically you can deposit business checks into a personal account, but the IRS may view this as commingling funds. If you are audited, you will have a harder time proving that business and personal expenses were kept separate. A business account costs little and solves this problem entirely.

What if my bank asks for a copy of my tax return?

Some banks ask for a recent business tax return (Form 1120-S for S corps) to verify that the business is real and active. If you are newly formed and have not filed a return yet, explain this to the bank. Most will open the account anyway, especially if you have your EIN letter and Articles of Incorporation.

Can I open an S corp account online, or do I have to go to a branch?

Many banks let you open an S corp account online by uploading your documents. Some require a video call to verify your identity. A few still require an in-person visit. Check the bank's website or call ahead to see what they require.

How long does it take to get my debit card and checks?

Debit cards usually arrive within 5 to 10 business days. Checks take longer—typically 7 to 14 business days—because they are printed to order. Some banks offer rush printing for an extra fee. In the meantime, you can transfer money between accounts or use online bill pay to pay expenses.
