What Happens If You Ignore Notice CP508C
You cannot renew your passport or get a new one. Existing passports may be revoked. You cannot travel internationally.
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
You must resolve the tax debt through payment, payment plan, or other arrangement. We can help you get decertified.
- 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.
