The first job is sorting what’s already there. A bookkeeper goes through the business bank and credit card activity, flags transactions that look personal, and confirms each one with you. Groceries, family travel, personal subscriptions, and home repairs charged to business accounts get pulled out of expense categories where they don’t belong. That cleanup is the foundation for everything else.

Once flagged, personal charges paid from business accounts get reclassified to owner draws or shareholder distributions, depending on your entity type. For a sole proprietor or single-member LLC, it’s owner draws. For an S-corp, it’s distributions. Either way, those transactions stop inflating your expense totals and stop understating your taxable income. This matters because deducting personal items as business expenses is exactly the kind of thing that turns a routine return into an audit problem.

The other direction matters too. When you paid for a legitimate business expense with a personal card or personal cash, that expense should still hit your books. A bookkeeper records it as a business expense with the offsetting entry going to owner contribution or a reimbursement liability if you plan to pay yourself back. Each one needs a receipt and a short note on the business purpose so the documentation holds up if it’s ever questioned.

The structural fix is what stops the mixing from happening again. One business checking account, one business credit card, and every business deposit and expense flows through them. Personal cards stay for personal life. If the practice operates as an S-corp, this separation isn’t just convenient, it’s part of respecting the corporate structure that protects you legally. For medical and dental practices in particular, clean separation also makes practice valuation and any future sale or partnership conversation much simpler.

Going forward, a monthly review process keeps things clean. Your bookkeeper reconciles the accounts, codes every transaction, and flags anything that looks personal so you can confirm or correct it. Catching a stray Target charge in February is a five minute conversation. Finding twelve months of mixed transactions next January is a cleanup project.
