Top 5 Things to Know About Audits for Your Business

Hello!

Most small business owners feel a sense of dread when they hear the word “audit.” Audits are often viewed as time-consuming, expensive, and stressful. Yet a clearer understanding of how audits work can ease concerns and help you handle them more confidently if the need arises.

Business Audit Truths

1. The chances of being audited remain very low

The 2026 IRS Data Book provides statistics about IRS audit activities in the previous fiscal year, showing that only 0.1% of S-corporations were audited. The rate for partnerships was even lower. For C corporations with balance sheets of $5 million, the audit rate stood at 0.3%. Separate statistics for Schedule C filers are not published.

The IRS has requested additional funding to expand audit coverage. While the agency announced plans to double the number of small-business audits in 2026, the overall percentage affected is still expected to remain modest.

2. Partnerships or partners—who gets audited?

Partnerships are generally examined under the BBA Centralized Partnership Audit Regime. This includes limited liability companies that file as partnerships. Audits occur at the entity level, and the partnership itself is responsible for paying any amounts due and adjusting the partners’ returns accordingly.

However, “small partnerships” (those with 100 or fewer partners, all of whom are individuals, C corporations, S corporations, or estates) may elect out of the centralized regime. In that case, the IRS audits the individual partners to verify how partnership items were reported.

3. If selected for audit, you have rights

An audit may be triggered for various reasons. If you agree with the findings, the matter can often be resolved quickly—sometimes through a simple correspondence audit. If you disagree, you still retain important rights.

You have the right to be represented by a tax professional, to receive courteous service, and to receive clear explanations of the IRS’s position. You must respond to information requests in a timely manner. IRS Publication 1 outlines your rights in greater detail.

4. The initial audit isn’t the final answer

You have the right to appeal audit results. The first step is an appeal within the IRS. If the total amount in dispute (tax, interest, and penalties) is $25,000 or less, you may request simplified procedures. Larger amounts generally require a formal written protest.

Publication 5 explains your appeal rights and the steps for filing a protest.

5. The IRS doesn’t have the last word

If you still disagree after the IRS appeal, you can take your case to court without first paying the disputed amount. The most common route is the U.S. Tax Court. You generally have 90 days from the date the IRS mails a notice of deficiency to file a petition.

When the amount in dispute is $50,000 or less, you may elect the simplified “small case” procedures under Title XVII, which are faster and less formal. Decisions in small cases cannot be appealed. Alternatively, you can pay the tax and then sue for a refund in U.S. District Court or the U.S. Court of Federal Claims.

Final thoughts

The best protection against an audit is accurate record-keeping from the start. Report all income, claim only the deductions and credits you can substantiate, and file on time (including extensions when needed).

If you are selected for audit, you may represent yourself, but most business owners find it helpful to consult a qualified tax professional. Professional guidance can clarify your options and often save both time and money in the long run.
