An audit notice in the mailbox tends to set off a small panic. The team at Tax Crunch sees that reaction all the time, and the first thing worth knowing is that an IRS letter rarely means what people fear. Most audits are narrow. The agency wants clarification on one or two line items, not a forensic teardown of your entire financial life. Once you understand how the process works and what your next move should be, a lot of the dread drains out of it.
Confirm the notice is real before you do anything
The IRS contacts taxpayers by mail. If someone calls claiming to be an agent and demands immediate payment, or emails a link asking you to “verify your account,” that is a scam. A legitimate notice arrives on paper, carries a notice or letter number in the upper corner (something like CP2000 or Letter 525), and references a specific tax year.
Match that number against the notices index on irs.gov, which spells out what each letter means and what it asks for. A CP2000, as one example, is not even a full audit. It signals that the income on your return did not line up with what an employer or brokerage reported, and the IRS wants you to agree or explain the gap.
The kinds of audits, and why most are not scary
Not every examination looks the same, and the type you receive changes how you should prepare.
- Correspondence audits are handled entirely by mail. They make up the large majority and usually concern a single deduction or a missing 1099.
- Office audits ask you to bring documents to a local IRS office for review of a few flagged areas.
- Field audits are the most involved, with an agent visiting your home or business. These are reserved for complex returns and larger discrepancies.
A mailed request for a donation receipt is a very different situation from a field examiner reviewing three years of a business’s books, so identify which one you are facing first.
Respond on time and only to what is asked
Every notice carries a deadline, often 30 days. Miss it and the IRS proceeds on its own assumptions, which seldom land in your favor. Put the date on your calendar and answer well before it.
When you respond, address the specific question and nothing more. If the letter asks about a home office deduction, send the lease, the square footage calculation, and the supporting receipts. Leave out unrelated bank statements or stray comments about other parts of your return. Examiners work from what is in front of them, and handing over more than requested is a reliable way to widen the scope of the review.
Gather your documentation
Pull together the records that back up the item in question. Depending on what triggered the notice, that can include:
- W-2s, 1099s, and K-1s
- Receipts and canceled checks for deductions you claimed
- Mileage logs for vehicle expenses
- Bank and brokerage statements
The IRS generally has three years from your filing date to open an audit, and six years when income was understated by more than 25 percent. Holding onto records for at least that long is the cheapest insurance against a stressful scramble later.
When to bring in representation
You have the right to representation in any dealing with the IRS, a protection written into the Taxpayer Bill of Rights. A single-line correspondence audit with clean paperwork is something many people answer on their own. The calculus changes when the dollar figures are large, when the audit reaches into business income, stock options, or rental property, or when you would simply rather not speak with an examiner yourself.
A CPA who is also a tax attorney can take over the conversation, deal with the agent directly, and keep the review tightly focused. That dual background carries real weight in California, where a federal audit often prompts a parallel look from the Franchise Tax Board. Coordinating both at once is where seasoned help pays for itself, and it is exactly the work Tax Crunch does for individuals and businesses across the Peninsula and San Francisco Bay Area.
If you disagree with the result
An audit closes with an examination report. Accept the findings and you sign and settle any balance due. Disagree and you can request a meeting with the examiner’s manager or take the dispute to the IRS Office of Appeals, an independent group that reviews these cases. The Taxpayer Advocate Service is another avenue if the process stalls or creates real financial hardship.
Talk to Tax Crunch before you reply
Handled early and calmly, most audits close without much drama. The errors that turn a routine notice into a real problem almost always trace back to ignoring the letter, blowing the deadline, or volunteering too much. If a notice has shown up and you want a clear read on what it means and how to answer it, Tax Crunch can review it with you and represent you from the first response through resolution.
