How “Just This Once” Expenses Turn Into Big Problems
If you’re using your personal card “just this once” to cover a business expense, you’re not alone—but commingling funds is one of the fastest ways to create tax headaches and messy books.
As a CPA/CFO, I see it lead to missed deductions, unsupported write-offs, and stressful audit trails because the story behind each transaction gets blurry. It can also weaken the legal separation between you and your entity (especially for LLCs and corporations), which is the opposite of what limited liability is supposed to protect. I have represented clients on IRS audits where comingling has been the catalyst for the clients inability to segregate expenses and ultimately elimination of expenses causing a tax underpayment and penalties..
The fix is simple: separate bank accounts + separate cards, and if you do pay personally, reimburse yourself with clear documentation and a consistent process. Clean separation isn’t “extra admin”—it’s credibility, clarity, and protection.
Let’s connect and explore transformative ways to add value by ensuring your books are clean and segregated.
