If you worry that an IRS audit could expose unreported income, questionable deductions, or years of inaccurate returns, the steps you take now matter. Accurate reporting, reliable records, and timely professional advice can help you prevent avoidable tax problems and defend legitimate positions. When past conduct creates potential criminal tax exposure, however, correcting the problem requires careful legal judgment.
No tax professional can guarantee that the IRS will never audit you. The agency uses computer screening, random selection, and examinations involving related taxpayers to identify returns for review. Even an accurate return can attract attention. Your strongest protection starts with understanding your obligations, supporting what you report, and addressing past noncompliance before the government limits your options.
Reconcile Your Income Before the IRS Questions It
Start by comparing your tax return with your actual financial activity. Review Forms W-2, 1099, and Schedule K-1 alongside bank statements, bookkeeping records, brokerage reports, and payment processor statements. Report taxable income even when a customer pays cash or a platform never issues an information return. If a payer reports an incorrect amount, request a correction and keep the correspondence. Ignoring the form leaves a discrepancy that the IRS will expect you to explain, often years later and without the records that would have explained it easily.
Business owners should understand the difference between gross payments, bank deposits, and taxable profit. Form 1099-K generally reports gross payment transactions without adjusting for items such as processing fees and refunds. Your records should explain those adjustments and identify duplicate reporting. A transfer between your own accounts or legitimate loan proceeds can explain a deposit without creating taxable business income, but only if you preserved the documentation that establishes what each transaction represents. In a cash-intensive business, that documentation is the difference between an explanation and an assessment.
Include cryptocurrency activity in that review. Certain digital asset brokers began reporting 2025 transactions on Form 1099-DA in 2026, and basis reporting for covered assets phases in for transactions beginning in 2026. A broker’s statement may still omit information you need to calculate the correct gain or loss, so maintain acquisition costs, transaction histories, and records of transfers between wallets. Reporting only the transactions that appear on an information return can leave taxable activity unreported. Reconcile your broker statements with your complete transaction history, including activity involving other platforms and wallets.
Foreign accounts require a separate compliance check. A U.S. person generally must file an FBAR when the aggregate value of foreign financial accounts over which that person has a financial interest or signature or other authority exceeds $10,000 at any time during the calendar year. File the FBAR separately with FinCEN. Reporting foreign income on your tax return does not replace the FBAR, and Form 8938 or other international information returns may also apply.
Claim Deductions You Can Substantiate Under Current Law
A legitimate deduction deserves proper documentation. Keep receipts, invoices, payment records, and explanations of business purpose as the transactions occur, not at the end of the year. Separate personal spending from business expenses and document the business portion of mixed-use costs. Whole-dollar rounding under IRS instructions is permissible. Inventing an annual expense total because it looks reasonable creates a different and far more serious problem. Vehicle and travel deductions carry particular substantiation requirements, so maintain contemporaneous records that establish the relevant amounts, dates, destinations, and business purposes.
Home office deductions remain available to qualifying self-employed taxpayers, including business owners who satisfy the applicable requirements. Generally, you must use the space regularly and exclusively for business and meet an additional qualifying-use test, such as using it as your principal place of business. Special rules apply to certain inventory storage and daycare uses. W-2 employees generally cannot deduct unreimbursed home office expenses attributable to their employment on their federal returns. Working remotely, by itself, establishes nothing. Review how the space is actually used before claiming part of your rent, utilities, or other home expenses.
Medical expenses and health insurance premiums require different analyses. Taxpayers who itemize generally can deduct qualifying unreimbursed medical expenses only to the extent those expenses exceed 7.5% of adjusted gross income. Eligible self-employed taxpayers may qualify for a separate health insurance deduction without that floor, subject to earned-income limits and other requirements, including restrictions involving eligibility for subsidized employer coverage. Do not deduct the same premium twice or claim expenses that insurance reimbursed.
Charitable deductions require attention to both substantiation and the rules for the relevant tax year. Obtain a timely written acknowledgment containing the required information for each contribution of $250 or more, and note that a cancelled check does not satisfy that requirement. Larger noncash gifts may require additional reporting and a qualified appraisal. Beginning with tax year 2026, individuals who itemize face a new charitable deduction floor generally equal to 0.5% of adjusted gross income, applied to cash and noncash giving combined, alongside other applicable limits. Taxpayers who do not itemize may deduct up to $1,000, or $2,000 on a joint return, for qualifying cash contributions to certain public charities, though contributions to donor-advised funds do not qualify. These changes apply to 2026 contributions, generally reported on returns filed in 2027, and they add a calculation step that did not exist before.
Before signing, review the completed return and question any deduction or credit you do not understand. A preparer’s assurance that everyone claims it substitutes for neither eligibility nor supporting records. If an expense, credit, or tax shelter depends on facts that do not match your circumstances, obtain independent advice before filing rather than after the IRS asks.
Address Past Tax Problems Before Your Options Narrow
Discovering an error does not mean you committed tax fraud. An amended return or delinquent filing may be the appropriate correction for an ordinary mistake. But if you knowingly concealed income, fabricated expenses, or deliberately failed to file required returns, speak with an experienced criminal tax defense attorney before submitting any correction or explanation. Filing an amended return does not, by itself, provide immunity from criminal tax prosecution, and it can supply the government with an admission it did not previously possess.
For eligible taxpayers with willful noncompliance involving legal-source income, the IRS Criminal Investigation Voluntary Disclosure Practice can offer a route back into compliance while limiting prosecution risk. It requires a timely, truthful, and complete disclosure, cooperation, and arrangements to satisfy the applicable tax, interest, and penalties.
Timing extends well beyond whether you have received an audit letter. An examination or criminal tax investigation closes the opportunity, and the IRS’s receipt of certain information about your noncompliance can make a disclosure untimely before you know the government holds it. For qualifying nonwillful offshore failures, the streamlined filing compliance procedures may provide another option. Counsel should assess eligibility and the underlying conduct before you choose a procedure or sign a certification under penalties of perjury. Waiting for the IRS to contact you can eliminate an option you could have used a month earlier.
Respond Carefully If the IRS Contacts You
Read the notice, identify the tax years and issues, and calendar the response deadline. The IRS initiates ordinary audits by mail. A CP2000 notice, by contrast, generally proposes changes based on information that does not match your return, and it is neither a formal audit nor a bill. Respond through the appropriate process with records that support your position. Ignoring a notice allows an incorrect proposed adjustment to move toward an assessment that is far harder to undo than it was to prevent.
Preserve the original records and obtain advice about the scope of any document request before you answer it. If records are missing, discuss legitimate reconstruction using bank statements, vendor records, calendars, and other reliable evidence. Never fabricate receipts, alter transactions, or create documents that falsely appear contemporaneous. Those actions can supply evidence of fraud and create additional criminal exposure, even when the original tax issue arose from an innocent mistake. You have rights to representation and to challenge IRS findings, but you must exercise them within the applicable deadlines.
Take particular care when an examination involves deliberate omissions or false statements. An eggshell audit involves a civil examination in which the taxpayer knows of potential criminal tax exposure that the examiner has not yet identified. In a reverse eggshell audit, a criminal tax investigation already exists while the taxpayer believes the matter remains solely civil. Both demand careful management of every statement, record, and communication, because each one can be read twice.
If an IRS Criminal Investigation special agent contacts you, obtain criminal tax counsel promptly and before agreeing to any substantive interview. Do not try to explain away serious discrepancies in an improvised conversation on your doorstep. Your answers can affect both civil and criminal proceedings. A later correction or retraction does not necessarily prevent the government from using your original statements.
How the Tax Law Offices of David W. Klasing Can Help
David W. Klasing is a dual licensed Tax Attorney and CPA who has spent his career at the point where tax accounting and tax law meet. That combination is uncommon, and it is the reason the firm can evaluate a disputed return as both a set of numbers and a legal position. Most taxpayers facing an IRS examination need someone who can do both, and dividing the work between an accountant and a lawyer who have never worked the file together rarely produces a coherent defense.
At the Tax Law Offices of David W. Klasing, we are staffed by dual licensed Tax Attorneys and CPAs and a supporting team of accounting professionals. We examine the transactions behind your returns, reconstruct financial activity where records are incomplete, identify the weaknesses an examiner will find, and assess how the government is likely to interpret the evidence. That assessment comes before any document goes to the IRS, not after.
In an active examination, our IRS audit representation focuses on controlling scope, substantiating legitimate positions, correcting an examiner’s erroneous assumptions before they harden into a proposed adjustment, and contesting penalties. At the Tax Law Offices of David W. Klasing, we handle the communications, respond to information document requests, and keep you out of conversations that serve the government rather than you.
Where the problem is historical rather than current, we bring taxpayers back into compliance on the most favorable terms available. That work includes filing years of delinquent returns, evaluating whether an amended return or a formal disclosure procedure fits the facts, assessing eligibility for voluntary disclosure or streamlined filing, and quantifying the tax, interest, and penalty exposure before you commit to a route you cannot reverse.
When an examination carries potential criminal exposure, we run it as a coordinated civil and criminal tax defense. Our dual-licensed tax attorneys & CPAs manage eggshell and reverse eggshell examinations, respond to summonses, deal with IRS Criminal Investigation special agents directly so that you do not have to, and build the defense from the first contact rather than after a referral has already been made.
If a case cannot be resolved with the examiner, we carry it forward. Our attorneys prepare protests to the IRS Independent Office of Appeals and, where necessary, take matters into tax litigation. Knowing how a case would be tried changes how it is developed from the beginning, which is one more reason to involve the firm early rather than once the record is already built.
You do not need to wait for an audit notice to address a tax problem that worries you. If you have unreported income, unsupported deductions, undisclosed foreign accounts, unfiled returns, or an IRS inquiry you cannot safely handle alone, contact the Tax Law Offices of David W. Klasing. Call (800) 681-1295 or reach us online to schedule a confidential, reduced rate initial consultation.
