Receiving a tax notice or letter is never a pleasant experience. It can be confusing and frustrating if you don't understand why you received the notice in the first place.  That's why we wrote [The Ultimate Guide to Tax Notices](https://www.dimercurioadvisors.com/the-ultimate-guide-to-tax-notices) and created a [tax notice library](https://www.dimercurioadvisors.com/learning-center/tax-notice-library) filled with the most common tax notices and letters you might receive.  We believe the process of staying compliant with your taxes should be as effortless as possible.

### General Information

- **What is the notice number?**  LTR2645C
- **What government agency sends this notice? ** The Internal Revenue Service (IRS)
- **What is this notice about? ** The IRS has received your correspondence or documentation, but they need additional time—usually 45 to 90 days—to complete their processing and provide a final response. Unfortunately, the IRS may send multiple letters like this if delays persist.
- **What should you do if you receive this notice? **Keep track of the timeline. If you continue to receive delay letters, consider following up so your case doesn’t stall.

### FAQs & Additional Information

- **Why does the IRS keep sending me letters with the same delay message?** The IRS issues multiple delay notices when they need extra time at each stage of review or processing.
- **Can I speed things up if the IRS is taking too long?** You can try contacting the Taxpayer Advocate Service, but they may only help if standard procedures aren’t being followed.
- **Does this mean I owe more taxes or am under audit?** Not necessarily. The notice primarily states the IRS needs extra time to address your case; it’s not an official audit or assessment of additional taxes.
- **What if the delay costs me interest or penalties?** You might seek relief if you can show the delay was due to a ministerial or procedural act by the IRS. That process often involves separate procedures or forms.
- **Should I just wait for the next letter?** It’s wise to follow up periodically rather than wait indefinitely, since the ultimate resolution requires active IRS action.
