The LTR 203C is the IRS's informational response to correspondence you sent. You asked a question, requested information, or submitted a request, and this letter is the IRS's reply. It's part of a general correspondence family that covers a wide range of account-related responses.
Don't Skim and File
Many taxpayers receive the LTR 203C, see that it's a response to something they asked about, and assume the matter is resolved. Read the full letter. Some informational responses include requests for additional documentation, explanations that require your confirmation, or descriptions of actions the IRS plans to take that you may want to dispute.
If the Response Answers Your Question
File the letter with your tax records for the relevant year. If the IRS took action on your account (applied a payment, corrected an error, adjusted a balance), verify the action by checking your IRS Online Account or requesting a transcript.
If the Response Is Incomplete or Wrong
Write back referencing the LTR 203C and explain what's still unresolved. Be specific. Quote the letter and identify exactly what needs correction or further explanation. General follow-ups generate general responses. Specific follow-ups get specific answers.
