When the IRS contacts you through mail, understanding whether you have received an IRS letter or an IRS notice is key to determining the urgency and necessary next steps.
What Is an IRS Notice?
An IRS notice typically indicates that the IRS needs you to take action. This may involve paying additional taxes, correcting information, or providing missing documents. Notices often contain codes (such as CP14, which means a balance due) that help identify the issue. They come with deadlines, and ignoring them can result in penalties or interest.
What Is an IRS Letter?
IRS letters are usually informational and less urgent. They clarify account details, confirm receipt of payments, or provide general tax guidance. For example, Letter 5071C is for identity verification; Letter 226J relates to Affordable Care Act shared responsibility penalties, which usually don’t require immediate payment.
Key Differences
| Aspect | IRS Letter | IRS Notice |
|---|---|---|
| Purpose | Inform or clarify without immediate action | Requests payment, response, or correction |
| Tone | Informative, explanatory | Direct, often includes deadlines |
| Examples | Letter 5071C (Identity Verification), Letter 226J (ACA info) | Notice CP14 (Balance Due), Notice CP2000 (Proposed Change) |
| Action Needed | Usually none or response without payment | Typically requires payment or response |
| Frequency | Less common, for specific cases | More frequent, issued to many taxpayers |
