Tax representation by a tax lawyer
Did the IRS claim that you did not report all your income? Did they disallow some of your expenses or deductions? Have you been audited, and the bank deposits were more than what you reported in sales and revenue? The IRS would generally recompute your taxes, and add stiff penalties and interest as well.
If you were being represented by a power of attorney, tax lawyer, CPA or an EA enrolled agent, your representative would have been able to explain to the IRS that not every deposit is income. Many taxpayers transfer funds from credit lines to meet urgent expenses, others obtain loans to pay accounts payable. So, to sum, not every deposit should be income to be taxed on.
