You mixed personal and business money. Here's the fix
If you used the business account for something personal, record it as an owner's draw, not an expense. If you paid a business bill personally, record it as an owner contribution or reimburse yourself. Then open separate accounts, because mixing funds complicates your books and can weaken your LLC's liability protection.

Quick facts
- Personal on business card. Record it as an owner draw, never an expense
- Business on personal card. Reimburse yourself or record an owner contribution
- Best fix. Separate bank and card accounts
What should you do when it's already happened?
Don't panic and don't delete anything. The fix is a category change. Each mixed transaction needs to end up in the right place.
| What happened | How to record it |
|---|---|
| Personal purchase on business card | Owner's draw or distribution |
| Business purchase on personal card | Expense, offset to owner contribution, or reimburse yourself |
| Personal money put into the business | Owner contribution |
| Paid yourself from the business, sole prop or LLC | Owner's draw |
If you're an S-Corp owner, be more careful. Personal spending paid by the corporation can turn into wages or distributions, and each has its own tax treatment. Talk it through before year end.
Why does it matter so much?
There are three real costs. Personal spending logged as an expense understates your income, which is a problem if the IRS looks at your return. Business spending buried in a personal account is easy to forget, so you overpay. And if you've got an LLC or corporation, treating the company account like your own can give a court grounds to look past your liability protection. Lawyers call that piercing the corporate veil. It's the reason you formed the entity, so don't weaken it.
How do you keep them separate from now on?
- Open a business checking account and a business credit card.
- Move every recurring bill and subscription to the business card.
- Pay yourself on a set schedule with a transfer, not by swiping the business card.
- If you slip, record it within the week while you remember.
What about expenses that are partly personal?
Your phone, car and home office can all be partly business. Only the business share is deductible, so keep a reasonable basis for the split. For vehicles, that means a mileage log. For your home, see the home office deduction. If years of this have stacked up, catch-up bookkeeping is the cleanest way out.

It's not automatically illegal, but deducting personal costs as business expenses is wrong, and regular mixing can weaken an LLC's protection.
Does a sole proprietor need a separate bank account?
It's not legally required in most cases, but it makes your books far cleaner and your records much easier to prove.
How do I reimburse myself for a business expense?
Transfer the amount from the business account to your personal account and record the original purchase as an expense, keeping the receipt.
