You will typically know if you are being audited within seven months to a year after filing your tax return, as the IRS generally initiates audits within this timeframe, though they can start up to three years later. Notification is sent via mail (not phone or email).
Remember, you will be contacted initially by mail. The IRS will provide all contact information and instructions in the letter you receive. If we conduct your audit by mail, our letter will request additional information about certain items shown on the tax return such as income, expenses, and itemized deductions.
Some audits, particularly those focusing on tax credits, start a few months after you file your return. Others, often related to questionable items on your return, generally start within a year after you file. The most comprehensive IRS audits, known as field audits, can start later.
If it still says "processing" that's actually a good thing. If your tax return ever is chosen for further review, or an actual audit, then the website should indicate that, and also let you know to expect an IRS notice or letter by mail. (You haven't observed a message like that, have you?)
When the IRS accepts your return and issues a refund, it doesn't mean your filing is approved or immune from scrutiny. Acceptance is just the first step in processing. The IRS can still audit you for up to three years after filing, or even longer in certain situations.
The IRS uses a combination of automated and human processes to select which tax returns to audit. Not reporting all of your income is an easy-to-avoid red flag that can lead to an audit. Taking excessive business tax deductions and mixing business and personal expenses can lead to an audit.
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.
An IRS notice may alert you to a mistake on your tax return or that it's being audited. You can verify the information that was processed by the IRS by viewing a transcript of the return to compare it to the return you may have signed or approved. You can access your tax records through your account.
Filers most commonly receive letters from the IRS notifying them of the examination in the fall or winter months of the previous tax filing year. Yet, the auditors can mail the notifications throughout the year.
Many people worry about IRS audits. But the chances of being audited are actually very low for most individuals. Recent IRS data shows the IRS examined 0.40% of individual returns filed and 0.66% of corporation returns filed. Most of the IRS's focus is on large businesses and high-income earners.
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 know the IRS might be investigating you through official mail (first contact), phone calls (often with automated messages to IRS.gov), or in-person visits, but signs of a criminal probe include contact with IRS Criminal Investigation (CI) agents, subpoenas to you or your bank, questions to your accountant/bank, unusual account activity (freezing/refusing transactions), or agents suddenly going silent after an audit. Key indicators are official IRS letters, contact from CI special agents, third-party inquiries, and formal summonses for records, signaling serious scrutiny beyond a simple audit.
However, you can reduce the chance of audit significantly by paying careful attention to detail and recognizing whether you are reporting a transaction of special interest to the IRS. And if you do get audited, having accurate and complete records and professional advice can make the process go more smoothly.
Mail audits are usually quick and straightforward
The IRS does these audits by mail, generally notifying taxpayers within seven months of filing. Mail audits usually wrap up within three to six months, depending on the issues involved and how quickly and completely you respond to the audit letter.
Audit tips and tricks key takeaways:
Audits are typically scheduled for three months from beginning to end, which includes four weeks of planning, four weeks of fieldwork, and four weeks of compiling the audit report. The auditors are generally working on multiple projects in addition to your audit.

If the deductions, losses, or credits on your return are disproportionately large compared with your income, the IRS may want to take a second look at your return. Taking a big loss from the sale of rental property or other investments can also spike the IRS's curiosity.
The CRA chooses a file for an audit based on a risk assessment. The assessment looks at a number of factors, such as the likelihood or frequency of errors in tax returns or whether there are indications of non-compliance with tax obligations.
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.
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.
