Personal credit card for business expenses
You should be careful about mingling your personal money and that of the business, even if it is a sole prop right now.  It is a good habit to keep separate business and personal bank/credit accounts just so that when you change to an LLC, it is simpler for you to separate what belongs to the company and what is yours personally.  What you're doing makes it more difficult (although only marginally so) to itemize business deductions that were paid with an ostensibly personal credit account.  The better habit to get into now is keeping that distinct separation between personal and business. That being said, there's nothing illegal in what you're doing, but it would make an accountant cringe, that's for sure. (chuckle) Hope this helps. Good luck!
