Why It Matters
If you operate a business — even a simple freelancing side gig — keeping business and personal money in the same account creates two problems:
-
Legal risk: If you have an LLC, commingling funds can "pierce the corporate veil," meaning a court can ignore your LLC's liability protection and go after your personal assets.
-
Tax headaches: At tax time, you'll need to separate business transactions from personal ones. With a shared account, this means reviewing every transaction for the entire year.
How to Set It Up
Step 1: Get an EIN
Apply for an Employer Identification Number (EIN) at irs.gov. It's free and takes 5 minutes. Use this instead of your SSN for business banking.
Step 2: Open a Business Checking Account
Use your EIN to open a separate checking account. Many banks offer free business checking for small businesses. All business income goes in, all business expenses come out.
Step 3: Pay Yourself
Transfer a regular amount from your business account to your personal account. This is your "pay." Keep it consistent — weekly or monthly. For sole proprietors, these transfers are called owner's draws and are not taxable events (you already pay tax on net profit).
The Rules
| Do | Don't |
|---|---|
| Deposit all business income into the business account | Pay personal bills from the business account |
| Pay all business expenses from the business account | Deposit personal income into the business account |
| Transfer a regular draw to your personal account | Use the business debit card for groceries |
| Keep records of every transfer between accounts | Mix personal and business cash |
Warning
If you have an LLC and a court finds you've commingled personal and business funds, you could lose your liability protection entirely. The LLC becomes meaningless, and creditors can pursue your personal assets.
Benefits at Tax Time
With separate accounts, preparing your Schedule C is straightforward: business account income = gross receipts, business account expenses = deductions. No sorting through hundreds of personal transactions to find business ones.
