IRS Audit Triggers Explained

Key Points

An audit does not mean you did something wrong. It means the IRS wants to take a closer look at your tax return.
Computers help spot returns to check. The IRS uses a scoring system to flag returns that may need a review.
Tax forms should match. If your return does not match forms like a W-2 or 1099, the IRS may send you a notice.
There are other reasons for an audit. The IRS may pick a return by chance or because it is linked to another audit.
Good records help. Keep receipts, bills, and other records to support what you report.

How might the IRS Choose a Tax Return for an Audit?

An audit notice from the Internal Revenue Service (IRS) can feel scary. But an audit does not mean you made a mistake or broke a rule. It means the IRS wants to check your tax return.

Here are some ways the IRS picks returns to review.

1. Computer Checks

The IRS uses a computer system to look for possible errors. One tool gives tax returns a number called a “DIF score.” This score helps the IRS decide which returns to review.

The system looks for things that differ from similar returns. For example, high business costs compared with income may lead to a closer look.

2. Random Selection

Some tax returns are picked by chance. These reviews help the IRS learn how well people follow tax rules.

If your return is picked this way, it does not mean the IRS found a problem.

3. Links to Other Audits

Your return may be linked to someone else’s audit. For example, the IRS may audit a business partner and then check your return.

The IRS wants to see if the details of shared business deals match.

4. Tax Forms That Do Not Match

The IRS gets copies of tax forms, such as W-2s, 1099s, and 1098s. It checks those forms against your tax return.

If the numbers do not match, the IRS may send a notice asking you to explain. This notice is not always an audit.

5. Staff Review

IRS staff also review tax returns. They may check items flagged by a computer to see if an audit is needed.

A flagged return does not always lead to an audit.

Keep Your Records in Order

Good records help you show that your tax return is correct. Keep receipts, bills, and logs of business costs. Store them where they are easy to find.

If you get an IRS notice, read it with care. Check what it asks for and when you must reply. Gather the records it requests. A tax professional can help you understand the notice and respond.
