We are sending you this letter because we need more information to complete the processing of your individual income tax return. This information can include:
- Missing forms or schedules to support your entries on Form 1040, 1040-A, or 1040-EZ
- Verification of income, withholding, and credit amounts
- Documentation to reconcile advance payments of the Premium Tax Credit (PTC). Please refer to PTC page for more information about letters regarding advance payments of the PTC.
