Why the IRS may think you earned more than you reported, and how New Jersey business owners can protect themselves.

The IRS can examine your business bank deposits and question whether you reported all your income. But not every deposit into your bank account is taxable income.

Loans, transfers between accounts, and money you personally put into your business can make your bank deposits look higher than your actual sales. If you cannot explain those deposits, you could face substantial additional taxes, penalties, and interest.

At Tomes Law Firm, we help New Jersey business owners respond to IRS audits, organize their financial records, and challenge proposed assessments that do not accurately reflect their income.

Why Does the IRS Look at Your Business Bank Deposits?

One method the IRS uses to determine whether a business reported all its income is called a bank deposits analysis. The IRS compares money deposited into your bank accounts with the income reported on your tax returns.

For example, suppose your New Jersey business reported $400,000 in gross receipts, but your bank statements show $550,000 in deposits. The auditor may want to know where the additional $150,000 came from.

You might have a perfectly reasonable explanation. But if you cannot provide records supporting that explanation, the IRS may propose treating some or all of the difference as additional business income. The IRS examination procedures recognize that nontaxable deposits and transfers must be identified in this analysis.

Does Every Bank Deposit Count as Taxable Income?

No. Money can enter a business account for many reasons unrelated to sales:

• Transfers between accounts. Moving $20,000 from one business account to another does not create another $20,000 in income.
• Business loans. Proceeds from a genuine loan generally are not taxable income because you must repay them.
• Owner contributions. Money you personally put into a business may represent a capital contribution rather than revenue.
• Certain refunds and reimbursements. Their treatment depends on the circumstances and the original transaction.
• Duplicate deposits. The same money may appear in multiple accounts and make deposits appear higher than actual sales.

The problem arises when these transactions are not properly documented. Remembering a transfer years later is different from having the statements to prove it.

A Real Example: How We Helped Luis Explain His Bank Deposits

Luis operated a seasonal business in New Jersey. Because income fluctuated throughout the year, he regularly transferred money between bank accounts to manage his cash flow.

When the IRS examined his bank deposits, those transfers made it appear that he had received more business income than he actually earned. Simply telling the auditor that the deposits were transfers was not enough.

At Tomes Law Firm, we took the initiative to reconstruct the transactions and create a detailed roadmap showing where the money originated, where it went, and how it moved between accounts. We matched deposits against withdrawals so the auditor could trace the funds.

Without that work, the transfers could have been treated as unreported income, potentially resulting in substantial additional taxes, penalties, and interest.

Luis’s case illustrates why a successful audit defense can require more than handing over records. It requires organizing the evidence and showing why the initial interpretation may be wrong.

What Happens If You Cannot Explain Your Bank Deposits?

The auditor may request more records and expand the examination. If deposits cannot be adequately explained, the IRS may propose additional taxable income, tax, applicable penalties, and interest. The examination may also expand to other years or other parts of the business.

Unexplained deposits do not automatically establish fraud. Poor bookkeeping is not necessarily tax evasion. But indications of intentional concealment can create more serious concerns. Business owners should obtain advice before making unsupported guesses about questionable transactions.

What If Your Bank Deposits Do Not Match Your 1099-K Forms?

Restaurants, retailers, contractors, and online sellers often receive Forms 1099-K from credit card processors or payment platforms. Those figures may not match what actually reaches the bank.

For example, a processor might report $300,000 in gross transactions, while depositing a lower amount after fees, refunds, or other adjustments. The difference alone does not establish unreported income.

An auditor may compare tax returns, bank deposits, Forms 1099-K, merchant statements, point-of-sale reports, and bookkeeping records. Fees, refunds, transfers, and timing differences must be reconciled. Businesses should not automatically agree that a difference between these records is omitted revenue.

Why Are Cash Deposits Especially Difficult During an IRS Audit?

Restaurants, contractors, retailers, and service businesses may receive cash payments. Cash transactions are legal, but accurate records matter. A contractor might receive reimbursement for materials, move personal money into the business, or withdraw cash to pay workers.

Years later, reconstructing those transactions can be difficult. Missing documentation can cause an auditor to question deposits and cash-paid expenses, including worker payments. Maintain records showing where cash came from and where it went.

Can the IRS Examine Your Personal Bank Accounts Too?

Yes, when relevant to a business examination, the IRS may request personal-account records, particularly where an owner mixes personal and business funds. Moving savings into a business account for payroll does not itself make the transfer business sales, but the owner may need to prove the source.

What If the IRS Auditor’s Calculations Are Wrong?

An auditor’s proposed assessment is not automatically correct, and business owners should not accept calculations they believe are wrong.

Suppose the IRS identifies $100,000 in deposits that appear to exceed reported revenue. A review might show that $60,000 represents transfers and $25,000 documented loan proceeds. Those findings can substantially change the proposed calculation.

Mistakes can occur if deposits are counted twice or if loans, transfers, fees, and refunds are not correctly considered. Without a clear reconciliation, however, an initial discrepancy can remain unresolved.

Our job is not merely to forward requests for documents. It is to understand the business, identify the problems, check the auditor’s calculations, and develop a strategy to address unsupported findings before they become costly assessments.

Why Shouldn’t You Handle a Bank Deposits Audit Yourself?

You know your business, but defending an IRS income examination is a different skill. A bank deposits audit can take months of gathering records, tracing funds, reconstructing activity, and responding to requests.

Every hour dealing with the audit is an hour not spent running the business. There is also a risk of providing incomplete explanations, unnecessary information, or agreeing to proposed adjustments without checking them. Representation can help organize the evidence and manage communication with the IRS.

What If the IRS Has Already Proposed Additional Taxes?

A proposed assessment is not necessarily final. Depending on the notice and procedural stage, you may be able to submit more evidence, challenge calculations, request a supervisor discussion, or seek an administrative appeal. Deadlines matter, so do not ignore the notice or assume the auditor must be right.

How Can New Jersey Business Owners Prepare Before an Audit?

Reconcile bank accounts regularly. Keep loan and owner-contribution records, preserve transfer documentation, and separate personal and business funds. Businesses using credit card processors or point-of-sale systems should reconcile merchant statements, sales reports, and bank deposits. Cash-intensive businesses should maintain accurate daily cash records.

Frequently Asked Questions

Can the IRS treat bank deposits as income?

Yes, the IRS can use a bank deposits analysis to identify potential unreported income. Documented nontaxable transfers, loans, and other items should be accounted for in the calculation.

Are transfers between my own bank accounts taxable?

Generally, moving your own money between accounts does not create income. Preserve records connecting both sides of the transfer.

What if my 1099-K does not match my bank deposits?

Processing fees, refunds, timing, and other adjustments can cause differences. Reconcile the underlying records before concluding that income was omitted.

Can I fight an IRS assessment based on deposits?

Yes. Depending on the circumstances and deadlines, you may challenge calculations, submit documentation, or pursue an administrative appeal.

Should I hire a tax attorney for a bank deposits audit?

An attorney experienced in IRS examinations can help trace funds, organize evidence, challenge unsupported calculations, and handle IRS communications.
