You usually cannot convert a personal account to a business account — you'll need to open a new one

Banks do not let you flip a personal account into a business account by changing a setting or filling out a form. The two are separate products with different legal structures, tax reporting, and account features. Your personal account stays personal. If you need a business account, you open a new one at your bank or elsewhere, then move your money and change where you direct deposits go.

The reason is structural: a personal account is tied to your Social Security number and personal credit, while a business account is tied to your Employer Identification Number (EIN) or your Social Security number as a sole proprietor. The bank's systems treat them as different customers. Starting fresh is faster and cleaner than asking a bank to rebuild your account from the ground up.

Key Takeaways

  • Personal and business accounts are separate products; you cannot convert one to the other, so you will need to open a new business account.
  • You can keep your personal account open while you use a business account, or close it once you have moved your money and updated your direct deposits.
  • Opening a business account takes one to three business days if you do it online with your current bank, or same-day if you go in person with your EIN or Social Security number and a business license or formation document.
  • Moving money between accounts is free; use a transfer, ACH, or wire depending on how much you need to move and how fast.
  • Update your employer, clients, and payment processors with your new business account number before you close your personal account.

What you need to open a business account instead

Most banks ask for an EIN (Employer Identification Number) if your business is registered as an LLC, S-corp, or C-corp. If you are a sole proprietor, you can use your Social Security number instead. You will also need a government-issued ID, proof of your business address, and either a business license, Articles of Incorporation, or an EIN letter from the IRS.

Some banks also want to see a business plan or tax returns if your business is new. Call your bank's business line before you go in or apply online — they will tell you exactly what they need. If you do not have an EIN yet, you can get one free from the IRS online in about 15 minutes, or by phone in one business day.

If you bank online-only (Chime, Ally, etc.), check whether they offer business accounts at all. Many do not. You may need to switch to a bank that has a business product, or use a fintech designed for small business like Square Cash for Business or Stripe.

How to move money from your personal account to your new business account

Once your business account is open, you have three ways to move money. The simplest is an internal transfer if both accounts are at the same bank — this is free and usually shows up the same day or next business day. Log into your personal account, go to Transfer, and send money to your business account by account number.

If your accounts are at different banks, use an ACH transfer (Automated Clearing House). This is also free and takes one to three business days. You will need your business account number and routing number. Your personal bank's website will have a "Transfer to Another Bank" or "External Transfer" option.

For large amounts or if you need the money today, use a wire transfer. This costs $15 to $30 and arrives the same business day, but you cannot reverse it if you make a mistake. Only wire if you are certain of the account details.

Updating direct deposits and automatic payments before you close your personal account

Before you close your personal account, change where your paycheck goes. Contact your employer's payroll department and give them your new business account number and routing number. This usually takes one to two pay periods to take effect, so do it as soon as your business account is open.

If you have automatic bill payments set up on your personal account (utilities, insurance, loan payments), log into each biller's website and update your account information. Do not rely on the bank to forward payments — some will, some will not, and you could miss a payment and damage your credit.

Check for subscriptions and recurring charges too: software, apps, memberships. Search your email for receipts from the last few months to find them all. Update each one before you close the personal account.

When to keep your personal account open and when to close it

You do not have to close your personal account. Many business owners keep both: the personal account for personal expenses and the business account for business income and expenses. This separation makes tax time easier because your accountant can look at one account and see only business activity.

If you want to close your personal account, wait until you have moved all your money, updated all your direct deposits and automatic payments, and confirmed that nothing is still trying to pull from it. Then call the bank or go in person and ask to close the account. The bank will ask if you want to keep any cards or services tied to it — make sure you say no to everything.

Some banks charge a fee to close an account if you close it within a certain time (often 90 days). Check your account agreement or call before you close to avoid a surprise charge.

What happens to your personal credit if you open a business account

Opening a business account does not affect your personal credit score. Banks do a soft inquiry (which does not show up on your credit report) or no inquiry at all. Your personal account stays in your name and continues to build your personal credit history.

However, if your business account is in your name as a sole proprietor, the bank may report late payments or overdrafts to your personal credit. If your business is an LLC or corporation and the account is in the business name only, those reports go to your business credit file instead, which is separate from your personal credit.

Frequently Asked Questions

Can I use my personal account for my business if I do not want to open a business account?

Technically yes, but it is not recommended. Mixing personal and business money makes taxes harder, gives you less legal protection if someone sues your business, and can raise red flags with the IRS. A business account is inexpensive (often free or $10 to $20 per month) and worth the separation.

Will my personal account number work for my business if I just tell people it is a business account?

No. Your personal account is tied to your Social Security number, not your EIN or business name. Clients and employers need the actual business account number. Using your personal account for business payments can also violate your bank's terms of service.

How long does it take to open a business account?

Same-day if you go in person with all your documents. One to three business days if you apply online. Some banks take longer if they need to verify your business license or EIN. Call ahead to ask your bank's timeline.

What if my bank does not offer business accounts?

Switch to a bank that does, or use a business-focused fintech like Square, Stripe, or Mercury. You can keep your personal account where it is and open the business account elsewhere. Moving money between banks is free via ACH transfer.

Do I need a business license to open a business account?

Not always. Sole proprietors can open a business account with just a Social Security number and proof of business address. LLCs and corporations need an EIN letter. Some banks ask for a business license, but many do not — call first to confirm what your bank requires.
