CHICAGO ( TheStreet) - It's the ultimate nightmare scenario for many business owners: a letter from the Internal Revenue Service informing them they're being audited.Statistically speaking, it's highly unlikely you'll be subjected to a tax audit this year. But if you are, it doesn't have to be a traumatic experience if you have the right preparation and expectations. Here's what you need to know: 1. DON'T flip out: Make sure your business is being audited. The IRS' document-matching computer system searches for discrepancies in tax returns and generates letters to taxpayers whose documentation is inconsistent. Receiving one of those written requests for clarification does not mean you're being audited. Provide what the IRS asks for, and you'll probably never even talk to an agent. If you do receive a letter informing you of an audit, you'll be asked to call and make an appointment for an agent to visit your office. Remember that an audit means the IRS needs to reconcile what they think you owe with what you've paid. Being audited doesn't necessarily mean you've done anything wrong or that you're facing penalties. As long as both sides act reasonably and rationally, tax issues are usually resolved with a minimal fuss. 2. DO provide what the IRS asks for -- and no more: Before your scheduled appointment with the IRS agent, you'll get a written request for certain documents. "The IRS tells you what they're looking for," says accountant Brad Jones, a partner with PBGH in Fredericksburg, Va. "You should provide exactly what they ask for, and be complete. Make sure all your receipts and invoices reconcile with your tax return. You don't want to create a situation where the agent is uncomfortable enough with your records to expand what they're looking at." At the same time, resist the urge to show off your stellar recordkeeping. The goal is to get the agent to move through your case quickly, not get distracted with irrelevant paperwork. 3. DON'T assume you've done anything wrong: The IRS occasionally does compliance audits for particular industries, looking for patterns of misrepresentation. Such audits can be time-consuming and drag on for several months. But companies in those industries are mostly chosen at random. Being picked doesn't mean the IRS has concerns about your business in particular.
