Frequently asked questions

While we accept most returns as filed, we select some for examination. We examine (or audit) some federal tax returns to determine if income, expenses, and credits are being reported accurately. We select returns for examination using various methods which can include random sampling, computerized screening, and comparison of information we received such as Forms W-2 and 1095-A. If we selected your return for examination, it doesn’t suggest that you made an error or were dishonest.

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

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

We'll disallow the PTC and send you an examination report showing the proposed changes to your tax return.

Tips for next year

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