IRS Letter 2645C
IRS Needs More Time to Respond to You
The IRS received your inquiry but needs more time to respond.
Deadline
No action required — wait for IRS response
Letter 2645C does not resolve your issue — it only confirms the IRS received your correspondence. Continue monitoring and follow up if you don't hear back in 60 days.
Important — act before this escalates.
What IRS Letter 2645C Means
Letter 2645C is an interim response letter from the IRS acknowledging that they received your inquiry, payment, or correspondence, but they need additional time to review and respond. This letter is common when the IRS is experiencing high processing volumes or when your case requires research beyond the standard timeframe.
This letter does not resolve your underlying issue — it only confirms receipt. The IRS is telling you to wait for a follow-up response. Typical wait times are 30–60 days from the date of Letter 2645C, but backlogs can extend this significantly.
If you submitted an amended return, a penalty abatement request, or a payment, Letter 2645C confirms it was received. However, do not stop monitoring your IRS account — the underlying notice or balance due may still be active while the IRS processes your response.
What the IRS Can Do If You Don't Respond

Frequently Asked Questions About IRS Letter 2645C
Does Letter 2645C mean my problem is resolved?
No — 2645C only confirms receipt of your correspondence. Your underlying issue (balance due, amended return, penalty abatement request) is still being reviewed. Wait for a follow-up letter.
How long should I wait before following up after 2645C?
Allow 60 days from the date of 2645C. If you haven't received a substantive response by then, contact the IRS at 800-829-1040 or use the Taxpayer Advocate Service if your situation involves financial hardship.
What if I have a pending levy while waiting for a 2645C response?
Pending enforcement is not suspended by Letter 2645C. Contact the IRS immediately by phone, or engage a tax professional who can intervene on your behalf to halt collection while your case is being processed.
I submitted an amended return — is 2645C my confirmation?
Yes — it confirms receipt. However, processing an amended return typically takes 16–20 weeks. 2645C is just an early acknowledgment; allow the full processing time before expecting a resolution notice.
