One of the most common cleanup jobs I see starts with a single card used for everything: inventory, software, groceries, a dog toy, the electric bill. Business and personal, all in one pile.
It works fine right up until tax time, when somebody has to go back and sort every line. Usually that somebody is you, squinting at a charge from eight months ago and trying to remember whether it was printer ink or a birthday present.
The fix is simple, and it’s one of the best things you can do for your books: give your business its own bank account and its own card.
Why mixing accounts causes headaches
When business and personal money share an account, every transaction becomes a small mystery. That leads to a few problems:
- Sorting takes forever. Each charge has to be reviewed and labeled by hand, often months after the fact.
- Deductions slip through the cracks. A real business expense buried among personal charges is easy to miss, and a personal one can sneak in where it doesn’t belong.
- You can’t see how the business is really doing. If the balance includes your personal spending, it’s hard to tell whether the business made money this month.
- Records are harder to back up. If questions ever come up about a return, a clean business account is much easier to explain than a year of mixed statements.
What the IRS and SBA say
You don’t have to take my word for it. In Publication 583, Starting a Business and Keeping Records, the IRS says one of the first things you should do when you start a business is open a business checking account, keep it separate from your personal account, and use it for business purposes only.
The U.S. Small Business Administration recommends opening one as soon as you start accepting or spending money as a business, and notes that keeping business funds separate can offer limited personal liability protection. If your business is an LLC or corporation, that separation is worth taking seriously, and your attorney can explain how it applies to you.
How to set it up
Here’s the setup I recommend to just about everyone:
- Open a business checking account. Banks commonly ask for your EIN, formation documents and any business license. Sole proprietors can generally use a Social Security number instead of an EIN.
- Get one card for business spending, and use it only for the business.
- Deposit all business income into the business account.
- Pay yourself by transfer. When you take money out for personal use, move it to your personal account rather than spending straight from the business account.
- Keep personal stuff personal. Groceries and dog toys go on your own card.
If something slips (it happens), don’t panic. Make a note of what it was and tell whoever keeps your books, so it gets recorded the right way.
Why January is a great time to start
You can open a business account any time, but starting with a new year has a nice bonus: the whole year lives in one clean place. With 2027 around the corner, now is a good time to call the bank, order the card, and line up your automatic payments so they’re ready to switch over at the start of the year.
Having owned a business myself before I got into bookkeeping, I know the “I’ll sort it out later” plan is tempting. Later always shows up, though, and it’s a lot friendlier when the sorting is already done.
