Common IRS Notices (and What to Do About Them)
Getting a letter from the IRS is never fun. But before you panic, take a deep breath—many notices are routine and can be resolved quickly. Every year, millions of Americans receive IRS notices about everything from simple math errors to major tax debts.
Whether you’re an individual or a business owner, this guide breaks down the most common IRS letters, what they mean, and how to respond.

1. CP2000 – Proposed Changes to Your Return
Why you got it: Something on your return doesn’t match what third parties (like banks or employers) reported.
What to do:
Compare the notice to your return.
If accurate, sign and send the form with payment.
If not, respond with supporting documents.
Don’t ignore it. This notice can turn into a bill.
2. LT11 or Letter 1058 – Final Notice of Intent to Levy
Why you got it: The IRS plans to seize your assets due to unpaid taxes.
What to do:
Act fast. You have 30 days to request a Collection Due Process (CDP) hearing.
Contact a tax professional.
Explore options like payment plans or Offers in Compromise.
3. CP504 – Unpaid Tax Bill
Why you got it: You’ve missed payment deadlines and the IRS is preparing to levy your state tax refund.
What to do:
Pay the balance or request a payment plan.
Consider talking to a tax specialist if you’re unsure how to proceed.
4. CP523 – Installment Agreement Default
Why you got it: You missed a payment or accrued new tax debt outside of your agreement.
What to do:
Don’t wait—call the IRS or a pro.
You may be able to reinstate your agreement without starting over.
5. CP3219A – Statutory Notice of Deficiency
Why you got it: The IRS made changes to your return and believes you owe more tax.
What to do:
You have 90 days to petition Tax Court.
If you ignore it, the balance becomes final.
This is serious—don’t delay action.
6. Letter 6470 – Identity Verification
Why you got it: The IRS flagged your return for potential identity theft.
What to do:
Follow the instructions to verify online or by phone.
You’ll need last year’s tax return and a photo ID.
Often this is routine, but it can delay your refund.
What If You Don’t Know What It Means?
IRS letters can be vague or confusing. If you don’t understand the notice—or if you’re worried about how to respond—it’s smart to talk to an Enrolled Agent who can help you resolve it.
Don’t Wait Until It’s Urgent
Early response = more options. Whether you missed a form, owe back taxes, or need identity verification, delaying action limits your ability to negotiate, appeal, or protect your assets.
