Serving an IRS Small Business Audit

Running a small business subjects an owner to assorted twists and turns on a daily basis. Few events, however, will raise an owner’s blood pressure quicker than a U.S. Department of Treasury letter informing the owner that the business included in their personal income tax return has been selected for an IRS audit.

Although the IRS overall audit rate for personal income tax returns is quite low – hovering around one percent each year – a significant portion of these returns include so-called “Schedule C” self-employed businesses. The Schedule C is a one-page tax schedule used by self-employed business owners to report their business’ income and expenses on their personal federal income tax return. Since Schedule C tax return amounts are presented in a summarized fashion, you can expect the IRS to be interested in the details supporting the summarized amounts.

The good news: according to the IRS’ latest statistics, approximately 75% of all personal income tax returns selected for audit are conducted through “correspondence” with the taxpayer. For self-employed business owners, these correspondence audits are usually narrow in scope and limited to providing information on specified types of income or expenses. Examples of IRS correspondence audit requests that a Schedule C self-employed business owner could receive include providing copies of business vehicle mileage logs or perhaps supporting documents used to substantiate business travel and/or entertainment expenses. The key point to realize in a correspondence audit is that the IRS typically focuses on documentation types of requests and does not inquire into technical tax law authorities which govern the treatment of income and expense events.

Self-employed business owners can frequently mail copies of correspondence audit information directly to the IRS. Care and diligence should be exercised so that the information provided accurately responds to the IRS’ request. If the information provided is sufficient to resolve the request, the inquiry is usually closed at that time and the business owner never personally meets with an IRS auditor.

In most instances a self-employed business owner should be able to address and respond to correspondence audit requests without hiring a tax professional such as certified public accountant (CPA), enrolled agent or attorney. Even in instances where a professional’s guidance or clarification is desired, a brief consultation with the professional will usually suffice.

The bad news: the remaining 25% of IRS personal income tax audits fall into the more extensive “field” audit category. Field audits involve situations where the IRS comes to the taxpayer’s home, place of business or other designated location for an extended period. The purpose of the audit will be much broader than a correspondence audit and likely require significantly more time, effort and tax expertise from the owner.

When owners become subject to a field audit of their Schedule C business activities, it is highly recommended that the owner contact a tax professional. While it may not be necessary for the tax professional conduct all aspects of audit, engaging a tax professional offers numerous advantages such as the following:

  • -gauging the scope of the audit or, if the scope is unclear, provide the initial contact with the IRS auditor to clarify and possibly influence the scope of the audit;


  • -assisting in quantifying areas of potential tax exposure and, where advisable, become proactive in disclosing errors to avoid the imposition of IRS penalties;


  • -actively asserting reasons why the business owner’s treatment of income and deductions is proper under the law;


  • -identifying areas of missed opportunities where deductions were inadvertently omitted or, in the alternative, capable of being accelerated; and


  • -determining whether the IRS auditor’s requests are unreasonable and worthy of being curtailed.


Once a correspondence or field audit has been completed, it is common for the self-employed business owner to owe some additional tax liability. It is hard to be perfect! In instances where the owner owes additional taxes, the owner will also owe interest expense calculated back to the date when the income tax return was originally due. Further, depending on the facts, the IRS may also impose discretionary penalties, the most frequent of which is the 20% “negligence” penalty. Although most penalties can be waived if the mistakes are attributable to reasonable causes, consideration should be given to the incremental costs to fight a penalty waiver battle which could be in excess of the penalty amount itself.

IRS audits are never fun, but if a business owner maintains reasonably accurate records and treats the auditor with professionalism, the pain and disruption to the owner’s business can be minimized.
