You filed your tax return on time and did your best to ensure everything was accurate. But then a letter arrives from the Internal Revenue Service (IRS). What should you do? First, try not to stress about it. Although most returns are accepted as filed, the IRS does review others to verify information.
Next, make sure you respond by the date noted in the letter. If a professional tax preparer, accountant, or someone else helped you file your return, let them know. Then gather your tax recordsâwhether theyâre locked in a fireproof box, saved to a secure hard drive, or stuffed in a drawer you havenât opened since tax timeâso youâre prepared to answer any questions.
Getting a letter from the IRS might cause you some anxiety, but it doesnât always mean something is wrong. In many cases, the IRS is just passing on information or asking for clarification. You might receive a notice if:
The notice letter will outline what steps you need to take.
If you donât respond to an IRS letter by the deadline, you could receive a statutory notice of deficiency. This legal notice gives you 90 days to petition the Tax Court to have your case reviewed.Â
If your return is selected for examination, the IRS will explain in its letter what to do next. If the audit is handled by mail, submit all documentation by the due date. You can request an in-person audit if you have too many documents to send easily.
If you are scheduled for an in-person audit, gather all the relevant documents and prepare for the meeting. It may be held at an IRS office, your business or home, or your attorney or accountantâs office. The examiner may ask questions about your financial records, business operations, or filing history. If you donât already have a tax attorney or accountant, it may be worth considering hiring one for an in-person audit.
After reviewing your documents, the IRS may respond in one of three ways:
If you donât agree with the outcome of an audit, you can request a conference with an appeals officer. The letter you receive from the IRS will explain how to begin the process. What happens next may depend on whether you owe more or less than $25,000.
IRS employees are expected to explain and protect taxpayersâ rights throughout the audit process. According to the agency, these rights include:
The Taxpayer Advocate Service is an independent organization within the IRS that helps with unresolved tax issues. You can reach the service at taxpayeradvocate.irs.gov or (877) 777-4778. The office may be able to help if you havenât been able to resolve a problem, canât pay what you owe, or believe the IRS isnât following its own rules.
Thereâs no guaranteed way to avoid an audit. The best you can do is file an accurate return and understand how the IRS decides which returns to review. Some common IRS audit triggers include:
Getting a letter from the IRS doesnât automatically mean thereâs a problem. You may have made a mistake that the IRS has already corrected, and you might not need to contact or speak to an IRS agent.
Still, itâs important to be prepared. File your return on time or request an extension if needed, and pay what you owe. Once itâs filed, keep a copy of your tax return and any supporting documentation for at least three yearsâor at least six years if you grossly underreported your income.
If you are selected for an audit, respond as requested. Keep in mind that one of your taxpayer rights is to pay only the tax you oweâno more, no less.
