Answers to Common Questions

Why was my return selected for audit?

While most returns are accepted as filed, some are selected for examination. The IRS examines (or audits) some federal tax returns to determine if income, expenses, and credits are being reported accurately. The IRS selects returns for examination using various methods which include random sampling, computerized screening, and comparison of information received by the IRS such as Forms W-2 and 1095-A. Having your return selected for examination does not suggest that you made an error or were dishonest.

What do I need to send?

Refer to Form 14950 we sent with your notice. It explains what supporting documentation to send.

What if I didn’t receive a Form 1095-A?

Contact the Health Insurance Marketplace for an original or a corrected statement.

What if I can’t provide the requested documentation?

We will disallow the premium tax credit and send you an examination report that shows the proposed changes to your tax return.

What if I didn’t file a tax return claiming the premium tax credit and someone else is using my name and social security number?

Contact us at the number listed on the top right corner of your notice. You can also refer to the IRS Identity Theft resource page for more information.

Can I file my tax return while I am being audited?

Yes, you should continue to file all required tax returns before the due date to avoid additional penalties and interest.

Tips for next year

Notify the Health Insurance Marketplace about changes in circumstances, such as income and family size changes, as they happen to allow the Marketplace to update the information used to determine your expected amount of the premium tax credit and adjust any advance payment amount.

Consider filing your taxes electronically. Filing online can help you avoid mistakes and find credits and deductions that you may qualify for. In many cases you can file for free. Learn more about e-file.
