What Happens If You Ignore Notice CP501
If ignored, you'll receive more serious notices and penalties will continue to accrue.
Every day you wait, penalties compound, interest accrues, and your options shrink. The IRS does not negotiate well with silence — they escalate.
What You Should Do Right Now
Pay the balance, set up a payment plan, or contact us if you can't pay or disagree with the amount.
- 1
Do not call the IRS phone number on the notice until you've spoken with an attorney — anything you say can be used against you.
- 2
Gather every page of the notice plus any prior IRS correspondence about the same tax year.
- 3
Call a senior tax attorney (not just any CPA or preparer) so attorney-client privilege protects the conversation.
- 4
Respond before the deadline — even a properly filed request for an extension or hearing buys you protection.
Why a Tax Attorney — Not a "Tax Relief" Company
Your conversations are legally protected. CPAs and enrolled agents do not have this protection in criminal or sensitive matters.
Our attorneys have negotiated thousands of cases. We know which IRS agents to call and what arguments actually work.
Properly filed responses can immediately pause levies, garnishments, and asset seizures while we negotiate.
If your case escalates to Tax Court, U.S. District Court, or criminal exposure, we can represent you there. Most firms cannot.
