#1 Do not move money into and out of your business and personal bank accounts for anything other than business purposes. If you do, you will have pierced the veil and it can have issues for you later on if you ever run into tax trouble or legal trouble and need to keep your business separate from you.
#2 You can put money into your business account and it is NOT income for your business. I think the issue you are having is that you are unsure of what is income and what isn't. Downloading your banking statements into a CSV file for Excel can be a problem. You sort by deposits and then sum that number? Hmm... But now it shows that $10,000 was put into the business by you, not from sales of goods or services. You do not show that $10,000 investment as income anywhere on your tax forms. You do show the $45,000 you made. And you do this with a Schedule C, not a K1. You are a single member LLC not a partnership. To the IRS you will have made $45,000. They don't care that you only paid yourself $30,000. You are a single member LLC so everything it makes is passed through to you. You only pay taxes once because the LLC doesn't pay taxes (besides state if applicable). The LLC passes all income and tax liabilities to you.
#3 Do not do what the original replier said to do. You should NEVER pay a personal credit card with your business account and vice versa. Why? Let's say that down the road you get into legal, financial or tax trouble. If your business was always a business and your personal finances were always left to be personal, entities cannot go after your business if you are in personal jeopardy. Again, vice versa. If your business runs into issues and you were using it like a piggy-bank it is no longer considered a separate financial entity and it can ruin the whole point of having a LIMITED LIABILITY company.
