Eggshell Audits

An eggshell audit is a civil IRS audit where the taxpayer has a potentially serious, often criminal, issue the IRS has not yet found. A small misstep can turn a routine examination into a referral, which is why a careful legal strategy from the outset is essential.

What an eggshell audit is

Eggshell audit is an informal term, not an official audit type, drawn from the expression walking on eggshells. It describes a situation where the taxpayer is being audited and either has information they do not want the IRS to find, the IRS suspects fraud, or both. The audit itself is civil, but it carries real potential to become a criminal investigation.

For example, a taxpayer may have significantly understated income, and the IRS already knows the income was underreported but is still deciding whether that was a mistake or intentional fraud. A finding of negligence means back taxes and a penalty. A finding of criminal fraud can mean a much larger penalty and the possibility of prison time.

Signs you may be in an eggshell situation

The clearest sign is knowing there could be a problem with your taxes, even if the IRS does not appear to be aware of it yet. An audit that seems unusually broad or unusually narrow, for example the IRS asking specifically about cryptocurrency, is another. A prior criminal investigation or previously filed inaccurate returns are signs as well, particularly if a current audit letter is requesting documentation that suggests the IRS is looking for more.

Civil versus criminal audits

The line between a civil and a criminal audit is thin. Civil audits focus on recovering unpaid tax; criminal audits investigate fraud and intent to defraud, aiming toward prosecution. An eggshell audit straddles that line, which is exactly why a solid legal strategy matters before the IRS detects a falsehood and escalates the case.

An attorney builds that strategy before the audit escalates: what to disclose, how to answer questions, and when to stay silent, so a civil audit does not develop into a criminal one. If a criminal referral has already occurred, that shifts into criminal tax defense.

What an eggshell audit attorney does

• Builds the legal strategy and controls communication with the IRS
• Reviews documents so nothing incriminating is handed over without a thorough legal review
• Negotiates with the IRS to avoid a referral to the Criminal Investigation Division
• Intervenes before a client accidentally admits to willful nondisclosure

Communications with an attorney retained for legal advice are generally privileged, so a taxpayer can discuss concerns about the audit freely. That lets the attorney plan for issues the IRS might find and watch for signs the auditor is preparing a criminal referral, which allows further planning.

When to call an eggshell audit attorney

Call as soon as an audit notice arrives. You should also call if you believe past filings were incomplete or inaccurate, or if you believe the IRS is already suspicious of criminal conduct, even if your accountant is uncertain whether that step is necessary. Ideally, look for an attorney experienced in both IRS audits and criminal tax defense.

A taxpayer in a sensitive audit is usually anxious, which makes deciding what to say harder. Lying to the IRS leads to more serious penalties, but there is also no need to admit to anything unnecessary. An attorney helps determine which questions to answer and which documents to provide, and can defend the client in criminal proceedings if the audit does lead to charges.
