To record a deposit that is not income, post it to a liability or equity account in your books rather than a revenue account, keep documentation showing where the money came from, and verify the amount never appears on your profit and loss statement. The deposit increases your cash balance and creates an offsetting entry that reflects what the money actually is: a loan you owe back, a transfer between your own accounts, an owner contribution, a refund, a security deposit, or an insurance recovery.
The reason the mechanics matter is that the IRS uses a bank deposits method to reconstruct income, and every deposit you cannot explain carries what the Internal Revenue Manual calls “an inherent appearance of income.”1Internal Revenue Service. IRS IRM 9.5.9 Methods of Proof Clean bookkeeping at the moment of the deposit is what keeps a legitimate non-income transaction from being reclassified as taxable earnings later.
Which Deposits Are Not Income
Federal law defines gross income as “all income from whatever source derived,” which is deliberately broad.2Office of the Law Revision Counsel. 26 USC 61 Gross Income Defined Several common deposits still fall outside it, and the Internal Revenue Manual identifies them as non-income items when examiners analyze bank records:1Internal Revenue Service. IRS IRM 9.5.9 Methods of Proof
- Loan proceeds, because you have an equal obligation to repay them. The lender can be a bank or a relative; what matters is a genuine repayment obligation.
- Transfers between accounts you own, such as personal checking to business checking. Ownership hasn’t changed.
- Gifts and inheritances, which are excluded from the recipient’s gross income under federal law. Future earnings on gifted or inherited property are taxable, but the principal is not.3GovInfo. 26 USC 102 Gifts and Inheritances4Internal Revenue Service. Publication 525 (2025), Taxable and Nontaxable Income
- Return of capital: refunds, rebates, and overpayment recoveries that give back money you already spent.
- Owner equity contributions, when the owner injects personal funds into the business and the deposit is not disguised compensation for services.
- Refundable security deposits received by a landlord. A deposit meant as the final month’s rent, however, is advance rent and counts as income immediately.5Internal Revenue Service. Rental Income and Expenses – Real Estate Tax Tips
- Insurance proceeds up to your adjusted basis in the damaged property. Any excess over basis is generally a taxable gain.6Internal Revenue Service. Topic No. 515, Casualty, Disaster, and Theft Losses
Pick the Right Account Before You Enter Anything
The offsetting entry has to hit the right place in your chart of accounts. Match your deposit type to one of these:
- Loan proceeds: credit a liability account, typically “Notes Payable” or “Loan Payable — [Lender Name].” A $25,000 loan debits cash $25,000 and credits the loan liability $25,000.
- Transfers between your own accounts: debit the receiving bank account and credit the sending bank account. No liability or equity account is involved.
- Owner contributions: credit an equity account such as “Owner’s Equity,” “Owner’s Investment,” or “Member Contributions,” depending on entity type.
- Security deposits received: credit a liability account like “Tenant Security Deposits.” The money is owed back until forfeited.
- Refunds and rebates: reduce the original expense account rather than creating new revenue. A $200 supplier rebate on a $2,000 supply purchase reduces the supplies expense by $200.
- Insurance proceeds: credit the asset account for the damaged property or an “Insurance Recovery” account. Consult your accountant if the payout exceeds your basis, because the gain portion is treated differently.
If you post any of these to a revenue category by mistake, you have overstated income and increased the tax you owe. Sole proprietors and other self-employed filers get hit twice, because the amount also flows through self-employment tax at roughly 15.3% on top of income tax.7Internal Revenue Service.

Entering the Deposit
The workflow is the same across QuickBooks, Xero, FreshBooks, and manual ledgers:
- Open the deposit or new-transaction screen.
- Enter the date exactly as it appears on the bank statement.
- Enter the amount to the penny.
- In the account or category field, select the liability or equity account you identified above. Not a revenue account.
- Use the memo field to describe the source specifically: “Loan proceeds from First National Bank, Note #4821” or “Owner contribution — working capital.” Write it so it makes sense two years from now without you in the room.
- Attach the supporting document (loan agreement, transfer confirmation, gift letter, insurance settlement) if the software allows file attachments.
- Save the entry.
Then run your profit and loss report and confirm the deposit does not appear. If it does, you selected a revenue account by mistake and need to edit the entry now, not later. When the monthly bank statement arrives, reconcile: date, amount, and description in your books should match the statement line. An unreconciled deposit sitting on your bank statement with no ledger entry is exactly the kind of unexplained item an examiner will flag.
Documentation to Keep With Each Entry
The bookkeeping entry is only half the defense. The paperwork is the other half, and it has to exist at the time of the transaction, not when a notice arrives.
Loans
A written agreement is the single most important record. Include the loan amount, the date funds were received, the repayment schedule, any interest rate, and both signatures. This holds for informal loans between family too. The IRS has stated that money lent to a relative or friend with the understanding it may not be repaid is a gift rather than a loan.8Internal Revenue Service. Topic No. 453, Bad Debt Deduction Keep the check image, wire confirmation, or bank record showing the transfer from the lender.
Transfers Between Accounts
Save statements from both the sending and receiving accounts showing matching amounts and dates. Most accounting software will link the withdrawal and deposit if you categorize them as the same transfer event.
Gifts and Inheritances
For a gift, get a signed letter from the donor stating the amount, the date, and that no repayment is expected. For an inheritance, keep the executor’s disbursement records or probate documentation. The donor may have a separate gift tax filing obligation for amounts above the annual exclusion, but that is on their side, not yours.
Owner Contributions
Keep a bank statement showing the withdrawal from your personal account and the matching business deposit, plus a short memo describing the purpose (“capital investment for equipment purchase” or “working capital injection”). For partnerships and multi-member LLCs, the contribution should track the operating agreement’s terms for capital calls.
Security Deposits and Insurance Proceeds
Landlords should keep the signed lease showing the deposit terms and any move-in inspection report. For insurance, retain the claim, the adjuster’s report, and the settlement letter showing what the payout covers.
Fixing a Deposit You Already Recorded as Income
Catch it in the current year, before you file: open the transaction in your software, change the account from the revenue category to the correct liability or equity account, save, and rerun the profit and loss to confirm the amount is gone from income.
Catch it after you’ve filed: amend the return. Individual filers use Form 1040-X, reporting the original income figure, the corrected figure, and the difference, with an explanation in Part II. File a separate 1040-X for each year that needs correcting.9Internal Revenue Service. Instructions for Form 1040-X (12/2025)
The refund window is three years from the date you filed the original return (including extensions) or two years from the date you paid the tax, whichever is later.9Internal Revenue Service. Instructions for Form 1040-X (12/2025) Miss it and the overpayment is gone even if the mistake is obvious on the face of the return.
Cash Deposits Over $10,000 Have a Separate Reporting Rule
Recording a deposit correctly in your books does not satisfy every obligation attached to it. A business that receives more than $10,000 in physical cash in a single transaction or in related transactions must file Form 8300 with the IRS within 15 days, regardless of whether the cash is income.10Internal Revenue Service. Form 8300 and Reporting Cash Payments of Over $10,000 A $12,000 currency deposit that is really a loan repayment still triggers the filing.
“Cash” here means physical currency, cashier’s checks, money orders, and bank drafts, not wire transfers or electronic deposits. A $15,000 wire from a lender does not require Form 8300.11Internal Revenue Service. IRS Form 8300 Reference Guide You also have to send a written statement to each person named on the form by January 31 of the following year, telling them you filed.10Internal Revenue Service. Form 8300 and Reporting Cash Payments of Over $10,000
For returns due in 2026, negligent failure to file Form 8300 carries a penalty of $340 per return, capped annually at $4,098,500 for businesses with gross receipts over $5 million and $1,366,000 for smaller businesses. Intentional disregard runs $680 per return with no annual ceiling.12Internal Revenue Service. IRM 20.1.7 Information Return Penalties
