Getting a letter from the IRS can be alarming, but most IRS notices are routine and can be resolved. Here is what to do.
Step 1: Do Not Ignore It
IRS notices have deadlines. Ignoring them can lead to additional penalties, interest, or more aggressive collection actions. Even if you disagree with the notice, you need to respond by the deadline.
Step 2: Read It Carefully
Note the following:
- The notice number (top right corner, e.g., CP2000, CP14)
- The tax year it refers to
- The response deadline
- What the IRS is asking you to do
Step 3: Do Not Call the IRS Yet
Before calling, gather your records. You will need your original return and any supporting documents. Calling without preparation often leads to long hold times without resolution.
Step 4: Contact Your Tax Preparer
Bring the notice with your original return, or call first for current secure document-delivery instructions. We can:
- Explain what the notice means
- Determine if the IRS is correct
- Prepare a response if needed
- Help resolve the issue
Common IRS Notices
- CP2000: Income discrepancy - the IRS received information that does not match your return
- CP14: Balance due - you owe money
- CP11/CP12: Math errors - the IRS adjusted your return
- Letter 5071C: Identity verification required
Important Reminders
- The IRS communicates primarily by mail, not phone or email
- Scammers frequently impersonate the IRS - verify any contact
- Never send personal information in response to unsolicited calls or emails
