Using a business credit card for personal expenses isn't illegal, but it can break your card's terms, and the issuer may close the account if it flags the charges. Chase says as much on its own education page, and most issuers write the same limit into their cardmember agreements.
Below is what happens if you do it, why it complicates your taxes and liability, and what to do if you already have.
The Difference Between a Business Card and a Personal Card
A business card is meant to cover business expenses only, and it helps owners keep personal and business finances separate. That pays off at tax time, when every deductible business purchase is already in one place.
As the company grows, you can add employees as authorized users and, in many cases, qualify for higher credit limits. Business cards also tend to carry rewards aimed at business spending.
The trade-off is protection. Personal cards carry the consumer protections of the CARD Act of 2009, and Chase notes that business credit cards don't have to offer the same protections. That can make disputing a charge harder.
Is It Illegal to Use a Business Card for Personal Spending?
No. Chase says it isn't illegal, but doing so may violate your card's terms and conditions. Many issuers' terms specifically forbid personal expenses on business accounts, so read the cardmember agreement for your card.
A single personal purchase is easy to note and back out of your expense totals when you file. A habit is different, because separating personal from business charges gets harder every month.
What Issuers Can Do
If an issuer flags non-business charges, it may have grounds to close your account entirely. That can mean losing the rewards you built up through legitimate business spending, so redeem or transfer points you've earned before a problem shows up.
Why It Complicates Taxes
Business expenses are usually deductible and personal ones aren't. A business card statement that mixes the two means sorting every line before you file, and deducting a personal charge by mistake is a problem of its own.
Why It Can Hurt Your Credit
Most business cards require a personal guarantee, which makes you personally responsible for the debt whether the charges were business or personal. Chase notes that unpaid balances can hurt both personal and business credit scores.
A large personal charge also uses up available credit, which leaves less for the business. If you're tracking a utilization ratio, a personal purchase counts against it too.
Why It Can Put Your Personal Assets at Risk
If you run an LLC or a corporation, the separation between you and the business is part of what protects your personal assets. Paying personal bills from business accounts blurs that line, and in a dispute a court may treat your business and personal finances as interchangeable. Ask an accountant or attorney how that applies to your entity.
If You Already Did It
Chase's advice is to pay the balance on time and in full, as soon as possible, and to record the charge for your bookkeeping. Going forward, put personal spending on a personal card. If you're weighing which cards belong on the business side, our guide to points and miles for business owners covers how the two sides work together.
