Commingled Funds in an LLC: Untangle Personal and Business Money

What do commingled personal and LLC funds do to my tax return?

Commingling means using one account or card for both personal and LLC money, such as paying groceries from the business account or taking customer payments into a personal account. It does not change what is taxable; it only makes the facts slow to prove. Customer payments are business income wherever they landed (26 U.S.C. 61), and personal, living and family expenses are generally not deductible (26 U.S.C. 262). Only ordinary and necessary business costs are (26 U.S.C. 162). The tax rule is the same for a sole proprietor with no LLC; the LLC protection section below applies only to an LLC.

Mixed accounts can damage a return in two ways:

• Personal spending can drift into expenses. The Schedule C instructions say to leave personal, living and family expenses out of Part V, other expenses, and the statute bars the deduction on any line.
• Customer money in a personal account can drop out of income. Some payers file Forms 1099 with the IRS, and the Schedule C instructions require a statement explaining any gap when Form 1099-NEC box 1 totals are more than the gross receipts reported.

A mixed-money case is not simple if any of these is true:

• A preparer is waiting or a return is due, and spending is split across cards and a personal account so you cannot tell which items are business.
• The mixed months are already on a filed return.
• The LLC has two or more owners, has elected to be taxed as a corporation, or added or lost a member during the mixed months. The number of members and any election set how an LLC is taxed (IRS).
• There are hundreds of transactions across several accounts, cards and payment apps, the books will not match the statements, or your Forms 1099 show more income than your deposits.

If a return is due before the cleanup is done, a calendar-year Schedule C return (Form 1040) is generally due April 15 and a partnership return (Form 1065) March 15 (Publication 509); Form 4868 or Form 7004 requests more time to file (Form 1065 instructions). Which returns your business files covers each return.

What to gather: every statement for the mixed months, last year's return, any Forms 1099, and receipts for large items.

How do I stop commingling funds today?

Stop new mixing first: send all customer money to one business account and pay all business costs from it, so the pile stops growing while you clean up. The IRS says to keep the business account separate from the personal account, deposit all receipts in it, use it for business only, and write checks to yourself only for personal withdrawals.

1. Open a business account if you have none. The SBA says to open one as soon as you accept or spend money as the business. What a bank asks for is covered in a business bank account for an LLC or sole proprietor.
2. Change where customers pay. Update invoices, payment links and payment-app payout settings so money lands in the business account.
3. Pay business costs only from the business account or a card used only for the business. Move recurring subscriptions onto it.
4. Pay yourself by one scheduled transfer from the business account to your personal account. A one-member LLC books it as an owner's draw and a multi-member LLC as a distribution; an S corporation must pay a working owner reasonable wages before distributions (IRS). See the section on more than one owner, below.
5. Record the past as it happened. Do not try to erase mixing by moving money back and forth; a transfer you make now is recorded on the day you make it.

What do I gather when spending is split across cards and a personal account?

Gather one statement per month for every account, card and payment app that touched business money, because you will sort from the statements. Include closed accounts.

The IRS says proof of payment alone does not establish a deduction, so keep the invoice or receipt that shows the cost was incurred for the business. If a receipt or canceled check is missing, see lost receipts for business expenses.

How do I sort every transaction?

Sort every line of the business account, and of any card or payment-app balance the business uses, into one of four buckets: business income, business cost, money you took out, or money you put in. Transfers, loans and equipment are set aside first (see below). In a personal account or card, sort only the lines that touched the business and leave the rest out of the books. The IRS says records should show where each receipt came from so that business and nonbusiness receipts, and taxable and nontaxable income, can be told apart, and suggests noting whether a deposit is business income, personal funds or a loan.

These names are for a one-member LLC. A multi-member LLC calls them distributions and contributions, and an S corporation handles them differently; see the section on more than one owner, below.

A single-member LLC owner cannot deduct personal withdrawals, and the Schedule C instructions bar a Schedule C deduction for federal income tax and self-employment tax (half of the self-employment tax is deducted separately, on Schedule 1). The same instructions send an owner's own health insurance and retirement plan contributions to Schedule 1 too, where you may be able to deduct them; keep them in draws and list them for your preparer. A transfer between two accounts that both hold business money, or a credit card payment, is neither income nor a cost: sort the card's charges, not the payment (credit card payments in the books). Money borrowed through a bona fide loan is not income (Publication 334): record it, and each repayment of principal, as a loan, a debt of the business (Publication 583), and sort the loan's interest as a cost.

Equipment, furniture and permanent improvements are not plain expenses (Schedule C instructions); list them for your preparer.

For a doubtful item, ask whether the cost is common and accepted in your line of work and helpful and appropriate for the business, which is the IRS test for ordinary and necessary. If you cannot tell, park it on a questions list and keep it out of expenses until a receipt settles it.

With hundreds of lines, work one month at a time, oldest first, and sort each statement by payee so a repeat charge gets one decision.

Two buckets have their own guides. Costs that are partly personal, such as a phone, car or internet, are covered in mixed-use expenses and the business percentage. Money you put in is covered in owner contribution or loan.

How do I book personal spending paid from the business account, and business costs I paid personally?

Personal spending paid from the business account is an owner's draw, not an expense. A business cost you paid personally is an expense, matched by money you put in.

For a single-member LLC, a business cost paid from personal funds is still a business cost: the LLC and its owner are one taxpayer for income tax (IRS), and the law allows expenses "paid or incurred" in the business (26 U.S.C. 162).

Each situation has a guide with the detail: one personal payment from the business account, business costs on a personal card and paying yourself back, and recording owner's draws.

Where do customer payments that landed in my personal account go in the books?

Customer payments that landed in a personal account are business income, recorded once. Where the money went afterward is a separate entry.

1. Record the income once, using the same accounting method as the rest of the books. Customers' payments count as income whichever account received them (26 U.S.C. 61).
2. Record where the money is. Money you move into the business account clears what the business was owed; it is not income a second time and not a new contribution. Money you kept and spent personally is an owner's draw.
3. Match the payer's Form 1099 to the income you recorded. The Schedule C instructions say to check Forms 1099 when reporting gross receipts.

The full treatment is in business income in a personal account.

How do I know the cleanup is finished?

The cleanup is finished when each business account, card and payment-app balance in your books reconciles to its statement for every month, and every business line, including those from personal accounts, is recorded once: in one bucket (income, business cost, owner's draw or owner contribution) or as a transfer, loan or equipment. The IRS reconciliation steps for a checking account work the same way for each business account:

1. Compare the deposits on the statement with the deposits in your books and note every difference.
2. Compare each payment on the statement with your books, and mark off what has cleared.
3. Prepare a reconciliation: start from the statement balance, add deposits not yet credited and subtract outstanding checks.
4. Enter items you had not recorded, such as bank fees, and correct any entry that was wrong. The adjusted statement balance should now equal the adjusted book balance.

Do this for each business account, oldest mixed month first; for a personal account, check only that each business line is booked once. The IRS says to reconcile a checking account each month, and a bank feed does not replace it (bank feeds are not reconciliation).

Then check three things: no uncategorized or "question" items remain; your sales records explain the business deposits and the Forms 1099; and you can explain the total of owner draws and the total of contributions. Count each sale once, and include sales with no Form 1099: all income is reportable. A Form 1099-K shows gross payments before fees and refunds, and can include personal payments such as gifts or reimbursements, so it need not match net deposits (IRS); see reconciling sales and payouts. For the full list before a preparer takes over, see the bookkeeping cleanup checklist.

Does commingling funds put my LLC protection at risk?

It may, but that is a state-law question, not a tax question, and this guide gives no legal advice. An LLC is created under state law, and the IRS notes that LLC members are generally not personally liable for its debts.

The SBA says a business bank account gives limited personal liability protection by keeping business and personal funds separate, and that an LLC's protection has limits. Whether mixed funds affect that protection is decided under your state's law, which this guide does not cover. If a lawsuit, a large debt or a personal guarantee is involved, a lawyer licensed in your state can say how it applies to you. Limited liability does not move the tax: a one-member LLC's income tax is the owner's own (IRS), and a member of an LLC with employees can be liable for employer-related penalties (IRS Publication 541). Clean books show which money was the LLC's and which was yours.

How do I avoid commingling funds in my LLC from now on?

Steps 2 to 4 above are the routine: every customer payment, including payment-app payouts, lands in the business account; business costs go on the business account or a business-only card; and you pay yourself by one scheduled transfer and take nothing else out. Three habits keep it that way:

1. You note the source of each deposit: business income, personal funds or a loan (IRS).
2. If you must pay a business cost personally, you keep the receipt that day and mark it "paid personally", so it can be booked as an expense with a matching contribution.
3. You reconcile every business account each month; the IRS says to do so for a checking account.

What if the mixed months are on a filed return, or the LLC has more than one owner?

A filed return, a second owner or an S corporation election each change what the cleanup must do, and each is a case for professional judgment.

Filed return. If the cleanup finds personal costs deducted or customer payments left out, the filed return may be wrong. The IRS generally has 3 years after the return is filed (a return filed early counts as filed on the due date) to assess more tax (26 U.S.C. 6501). The period is 6 years if the return leaves out more than 25% of the gross income it shows (for a business, total receipts before cost of goods sold), and not limited if no return was filed or the return was fraudulent (IRS Publication 583, Table 3). A deduction that should not have been claimed can also draw the 20% accuracy-related penalty on the underpayment; tax reported on a qualified amended return filed before the IRS first contacts you about examining that return generally stays out of it, unless the position was fraudulent (26 CFR 1.6664-2(c)). If the cleanup finds business costs the return left out, that is a refund claim, generally due within 3 years of filing or 2 years of paying the tax, whichever is later (26 U.S.C. 6511). Whether to amend, and for which years, depends on the facts. See amending a return for business expense mistakes and how long to keep business records.

More than one owner, or an S corporation. The same money is booked differently depending on how the LLC is taxed (IRS).

Partners and S corporation owners also face capital-account, basis and payroll questions that this guide does not answer.

Example

These examples are illustrative; all figures are in US dollars.

Single-member LLC consultant, one year

A consultant's single-member LLC, taxed by default on Schedule C, receives $90,000 in customer payments over 12 months, all into the business account. The statements also show $14,000 of personal costs (groceries and home rent) paid from that account, and a $6,000 software subscription paid on a personal card. The raw books counted every payment out of the business account as an expense and left the software out.

• The $14,000 moves out of expenses and into owner's draws. Profit rises by $14,000.
• The $6,000 is added as an expense with a matching $6,000 contribution. Profit falls by $6,000.
• Net, profit is $8,000 higher than the raw books showed, and the books now show what the owner took out.

Freelance designer, client payments in a personal account

A designer's single-member LLC, taxed by default on Schedule C, has clients who pay $8,000 in each of two months into her personal account. All $16,000 is business income, recorded once. At the end of month two she moves $16,000 into the business account; the transfer clears what the business was owed and is not income again. If she had spent $2,000 of it on rent and moved only $14,000, the full $16,000 is still income and the $2,000 is also an owner's draw.

Two-member LLC pays one partner's car loan

A two-member LLC taxed as a partnership pays $3,000 on one member's personal car loan from the business account. Assume it is a personal withdrawal, not pay for services or repayment of money the LLC owes the member. Then it is not a business cost; it is booked as a distribution to that member. Pay for services needs separate classification: an amount set without regard to the LLC's income may be a guaranteed payment, which the partnership generally deducts (IRS Publication 541); see guaranteed payments versus partner draws. An LLC that had elected S corporation status could instead have a distribution, wages or a loan; see the S corporation guide.

Different for you?

• You have months of mixed statements, a preparer is waiting or a return is due, and you cannot tell which items are business; or the books will not match, or your Forms 1099 show more income than your deposits: how far back the cleanup must go, whether a filed return is affected, and who rebuilds the books are judgment calls. Start with bookkeeping help, and see catch-up bookkeeping cost.
• The mixed months are already on a filed return: read amending a return for business expense mistakes and get bookkeeping help to rebuild the affected months.
• The LLC's only owner is not a US citizen or resident, or is a non-US company: the LLC must file Form 5472 for any year it has a reportable transaction with its owner, such as a contribution or distribution, and failing to file or to keep the records carries a $25,000 penalty (Form 5472 instructions). Mixed money makes that log hard to build: see Form 5472 records for a foreign-owned LLC and get bookkeeping help.
• Your LLC has two or more members: see guaranteed payments versus partner draws, partner capital accounts and partner-paid LLC expenses.
• Your LLC is taxed as an S corporation, paid your personal bills or owes you for costs you paid: see S corporation paying personal expenses and S corporation expenses never reimbursed.
• Rent from rental properties is mixed with personal money: see a separate bank account for each rental property.
• Your books are months or a year behind: see catching up on overdue books.
