The #1 Rule of Business Finances: Don't Mix Them

If there is one piece of advice we could give to every single new business owner, it would be this: open a separate bank account for your business on day one. It sounds simple, but failing to do so is the single most destructive—and common—mistake we see entrepreneurs make. This practice, known as "commingling funds," can cripple your business before it even has a chance to succeed.

Danger #1: You Pierce the Corporate Veil

The primary reason you formed an LLC or corporation was to create a legal shield between your business and your personal life. If your business is sued, this shield is supposed to protect your personal assets, like your house and your car. When you consistently use your personal bank account to pay for business expenses (or vice-versa), you are telling the courts that you don't see a real separation between you and your business. In a lawsuit, a lawyer can argue to "pierce the corporate veil," and if they succeed, your personal assets are suddenly at risk. Your liability protection becomes worthless.

Danger #2: You Have No Idea if You're Profitable

When your business transactions are mixed in with your grocery bills, mortgage payments, and family vacations, it is impossible to get a clear picture of your company's financial health. You can't run a meaningful Profit & Loss statement because your business expenses are hopelessly tangled with your personal ones. You end up managing your business based on a "gut feel" of your bank balance, with no real data to tell you if you're actually making or losing money.

Danger #3: You're Creating a Tax Nightmare

Imagine handing your accountant a year's worth of bank statements where every other transaction is a personal expense. The time it takes for them to sort through that mess is time you are paying for at their hourly rate. Even worse, this poor record-keeping is a massive red flag for the IRS. In the event of an audit, if you can't easily prove which expenses were for business, those deductions can be disallowed, leading to a huge tax bill plus penalties and interest.

The Simple, Non-Negotiable Solution

The fix is incredibly simple, and you must do it on day one:

1. Go to the bank and open a dedicated business checking account.
2. Get a dedicated business debit card and/or credit card.
3. Run 100% of your business income and expenses through these accounts. Pay yourself a formal salary or owner's draw from the business account to your personal account.
