What Happens If You Ignore Tax Notices in California?

Marc Boulanger • July 14, 2025

Let’s be honest — tax notices are scary. It’s tempting to toss them in a drawer, ignore the deadlines, or tell yourself you’ll deal with it later.


But in California, ignoring tax notices from the IRS, Franchise Tax Board (FTB), or CDTFA can lead to serious consequences — including:


  • Frozen bank accounts

  • Wage garnishments

  • Liens on your property or business

  • Business suspension or license revocation

  • Criminal charges in extreme cases

The longer you wait, the harder (and more expensive) it becomes to fix.



This post breaks down what actually happens when you ignore a tax notice — and what you should do instead.


Common Tax Notices (and What They Mean)

Agency Common Notices What They Lead To
IRS CP14, CP504, LT11, Letter 1058 Levy of wages, bank accounts, Social Security
FTB FTB 4905, FTB 4930, Demand Notices Liens, suspended entities, bank levies, garnishments
CDTFA Notice of Determination, Intent to Levy Sales tax liens, asset seizure, criminal referral

What Happens If You Ignore IRS Notices?


The IRS sends notices in escalating order:


  • CP14 – You owe taxes

  • CP504 – Intent to levy state refunds

  • Letter 1058 / LT11 – Final Notice of Intent to Levy

If you don’t respond within 30 days of LT11, the IRS can:


  • Garnish wages

  • Levy your bank account

  • File a federal tax lien

  • Start collection actions without further warning


What Happens If You Ignore FTB Notices?


The FTB enforces California income tax, business tax, and LLC fees. If you ignore:


  • FTB 4905/4930 – They will levy your bank account in as little as 10 days

  • They can also suspend your LLC or S-corp, preventing legal business operation

FTB notices often result in:


  • Franchise tax assessments

  • Refund offsets

  • Bank account levies without court approval

  • Vehicle or professional license suspensions
    

What Happens If You Ignore CDTFA Notices?

CDTFA handles sales and use tax, fuel tax, tobacco tax, and cannabis tax. Their notices often lead to:


  • Estimated assessments (even if you didn’t file)

  • Liens and levies without court proceedings

  • Field audits and asset seizures

  • Criminal prosecution in cases of fraud or tax evasion

If you don’t respond to a Notice of Determination, the tax becomes final in 30 days and collections begin immediately.


Compounding Consequences of Inaction


Ignoring tax notices creates a domino effect:


  • Penalties and interest stack quickly

  • You lose appeal rights

  • Collection actions begin

  • You appear uncooperative

  • Enforcement agents become more aggressive

  • You limit your resolution options (e.g., Offer in Compromise may be denied)

What to Do Instead


If you received any tax notice, act immediately:


  1. Don’t panic — read it carefully

  2. Identify the agency (IRS, FTB, or CDTFA)

  3. Contact a tax resolution professional

  4. Respond before the deadline

  5. Negotiate resolution options (Installment Agreement, OIC, hardship)

  6. Document everything

Frequently Asked Questions

What happens if I ignore an IRS tax notice?

The IRS will eventually garnish wages, levy your bank account, or file a lien if you don’t respond to final notices like Letter 1058.

Can the FTB really freeze my bank account?

Yes. The FTB can issue a bank levy without court approval, often within 10 days of sending a demand notice.

Does CDTFA take legal action if I ignore them?

Yes. The CDTFA can file liens, levy accounts, or refer cases for criminal prosecution if you ignore audit or collection notices.

What if I didn’t receive the tax notice?

Agencies consider notices delivered if sent to your last known address. Not receiving it usually doesn’t excuse non-response.

Can a CPA respond to notices for me?

Yes. A CPA with power of attorney can contact the IRS, FTB, or CDTFA directly to stop collections and negotiate resolutions.
