Making a mistake on your taxes and getting audited usually results in paying the correct, adjusted tax amount plus interest and potential penalties (often 20% or more). While the IRS will issue a notice and may disallow deductions lacking documentation, most "honest mistakes" do not lead to criminal charges. You can avoid penalties if you can justify the items under review.
The IRS does not check every tax return. It does not check the majority of them, but the IRS implements methods that track certain factors that would result in a further examination or audit by them.
What happens during an audit? Internal audit conducts assurance audits through a five-phase process which includes selection, planning, conducting fieldwork, reporting results, and following up on corrective action plans.
If there is a potential discrepancy, a tax examiner will look further into your reported income. They'll compare the information reported to the IRS by employers, banks, businesses, and of payers to the income, credits, and deductions on your report.
One-time forgiveness, officially known as First-Time Penalty Abatement (FTA), is an IRS program that allows qualified taxpayers to have certain penalties removed from their tax accounts.
Avoid These Common Tax Mistakes
Criminal matters can have serious consequences, including fines and imprisonment. The IRS may initiate criminal proceedings if they suspect a taxpayer has willfully committed tax fraud or tax evasion. This may involve falsifying information on federal tax returns, hiding income, or claiming false deductions.
If the IRS proves willful misconduct, you may face criminal charges, fines, and— in severe cases—prison. Most taxpayers, however, receive civil penalties only. Refunds are paused until the audit finishes.
You can still change your tax return by sending a request to the Canada Revenue Agency (CRA) after you have received your notice of assessment. Sign into My Account to make a change online. Select “Change my return” and make your request. If you filed your taxes online, you can use ReFILE to change your return.
The "20k rule" refers to the traditional IRS threshold for reporting income from payment apps and online marketplaces on Form 1099-K: over $20,000 in gross payments AND more than 200 transactions in a calendar year. While a law (the American Rescue Plan) temporarily lowered the threshold to $600, recent legislation, the One Big Beautiful Bill Act (OBBBA) (OBBBA), has reinstated the $20,000/200-transaction rule for tax years starting in 2025, providing relief for casual sellers and gig workers.
To avoid the 22% tax bracket (or any higher bracket), focus on reducing your taxable income through strategies like maxing out 401(k)s and HSAs, deferring bonuses, tax-loss harvesting, smart charitable giving, and strategic asset location, understanding that higher rates only apply to income within that bracket, not your entire income.
Unreported income
The IRS receives copies of your W-2s and 1099s, and their systems automatically compare this data to the amounts you report on your tax return. A discrepancy, such as a 1099 that isn't reported on your return, could trigger further review.
We may be able to remove or reduce some penalties if you acted in good faith and can show reasonable cause for why you weren't able to meet your tax obligations. By law we cannot remove or reduce interest unless the penalty is removed or reduced.
Audit tips and tricks key takeaways:
The 5 Cs of audit (Criteria, Condition, Cause, Consequence, Corrective Action) are a framework for structuring clear, actionable audit findings, explaining what should be (Criteria), what is found (Condition), why it happened (Cause), what the impact is (Consequence/Effect), and how to fix it (Corrective Action/Recommendation) to drive organizational improvement and compliance.
