- You did not pay the full amount due with your return.
- A correction was made to your return when it was processed which resulted in additional tax due.
- Interest and/or Penalty were assessed for late payment of tax due or for underpayment of estimated tax.
- Your return was adjusted based on an audit which resulted in additional tax due.
Look up your notice under "I Received a Notice" to learn more about the notice you received and what to do next. If you have questions about the notice you received, you may call the number provided on the notice you've received to speak with a representative.
