Personal and Business Money Mixed Together
Groceries on the business card, supplier bills from your personal checking. It is the most common mess we see, and it is sorted transaction by transaction.
What this usually looks like
It runs in both directions. Personal spending goes through the business account or card because that was the card in your hand. Business costs get paid from a personal account because the business account was short that week. Customer payments land in whichever account the customer had on file.
After a year or two, neither account describes the business. The business account overstates expenses with personal items, and real business costs sit in a personal account where no bookkeeper has ever looked.
Why it matters
- Personal spending recorded as a business expense is a deduction you are not entitled to
- Business costs paid personally and never recorded are deductions you are missing
- Business income deposited to a personal account can go unreported without anyone intending it
- For an S corporation, personal spending from the company is a distribution or a loan to you, and each is treated differently
- For an LLC or corporation, treating the company account as your own is one of the things a court can look at when deciding whether the liability protection holds. That is a legal question, and one for an attorney
How we separate it
- Bring every account that carried business activity into scope, including the personal ones
- Go through the business accounts and move personal spending out of expenses and into owner draws or distributions
- Go through the personal accounts and pull the business items in, recorded as money you put into the business
- Ask you about the unclear ones in a single list, grouped by vendor
- Reconcile the business accounts, and record the personal-account items against their statements so each has support
Mixed-use costs such as a vehicle, a phone or a home office are handled on their own basis at tax time. They are not split by guesswork inside the books. See the home office deduction for one example.
Stopping it from happening again
One business checking account, one business card, and a regular transfer to pay yourself. When you do pay for something personally, record it as an owner contribution that month. That is the whole fix, and it is cheaper than sorting it out afterwards. Staying caught up has the routine.
Frequently asked questions
Is it illegal to pay personal expenses from my business account?
For a sole proprietor it is not illegal, but the personal items cannot be deducted, so they have to be recorded as draws. For an LLC or corporation it also weakens the separation between you and the company, which is a legal risk to raise with an attorney. In every case the books have to show the spending for what it was.
Do you need my personal bank statements?
Only for accounts that paid business costs or received business income, and only to pull those items out. Personal transactions that have nothing to do with the business are left alone.
Can I still deduct business expenses I paid personally?
Generally yes, if they were ordinary business costs and there is a record of the payment. They are entered in the books as money you contributed to the business. Without a record they are much harder to support, so the personal statements matter. See missing receipts and records.
What happens to personal spending already claimed on a filed return?
If the amounts are significant, the return may need correcting. We look at the size of it once the books are rebuilt and tell you whether an amended return is worth filing.
