Introduction: Owing Over $100,000 Isn’t Hopeless — But You Can’t Ignore It


If you’ve received notices from the IRS or California Franchise Tax Board (FTB) and your total back tax balance has grown to over $100,000 — you’re not alone.

But at this level, you’re now in a special enforcement category — and the response must be strategic. This guide explains what to do if you owe six figures in tax debt, how high-debt cases are handled, and how Orange County taxpayers can manage or settle large IRS tax debts without losing everything.


🚨 Why $100,000+ Matters to the IRS and FTB


When your tax debt crosses six figures:


  • You’re flagged for revenue officer assignment
  • You may be referred to IRS Field Collection or FTB Legal
  • You’re more likely to face:
  • Wage and bank levies
  • Federal or state tax liens
  • Passport restrictions (IRS only)
  • Business suspension (FTB)
  • Potential litigation for collection


✅ Step-by-Step: What to Do If You Owe $100,000+


✅ 1. Stop Ignoring the Notices


At this point, collection letters (CP14, CP504, LT11, Letter 1058, etc.) are serious. If you're seeing:

  • “Intent to Levy”
  • “Notice of State Tax Lien”
  • “Proposed Assessment”


...you’re already in enforcement territory and may still have time to reduce large IRS tax debts through settlement before the IRS escalates.


👉 IRS Letter 1058 – Final Notice of Intent to Levy


✅ 2. Request IRS and FTB Transcripts


Your CPA should pull:

  • IRS Account Transcripts (wage/income, balances, history)
  • FTB Account Summary and Balance Letters


This will show:

  • What’s owed
  • What’s collectible
  • What’s still within the statute of limitations
  • Where penalty and interest are compounding — and whether you can cut penalties to lower total debt.


✅ 3. Get Compliant With All Filings


Both the IRS and FTB will not negotiate until all required returns are filed.


Your CPA can:

  • Request wage & income transcripts
  • Reconstruct missing years
  • File corrected returns to reduce inflated substitute assessments


✅ 4. Know Your Resolution Options


If you can’t pay in full, you might spread large balances over time with an Installment Agreement or qualify for an Offer in Compromise.


Option When to Use
Installment Agreement If you can afford full monthly payments
Partial Pay Agreement If you can pay something, but not the full debt
Offer in Compromise If you can’t pay and qualify for settlement
Currently Not Collectible (IRS) If paying would cause hardship
FTB Hardship Deferral Similar to CNC for California
Penalty Abatement If you qualify for first-time or reasonable cause relief


👉 FTB Offer in Compromise vs Installment Agreement


✅ 5. Avoid These Common Mistakes


  • ❌ Don’t make small “good faith” payments without a plan
  • ❌ Don’t ignore wage garnishments
  • ❌ Don’t sign up with high-pressure tax relief firms
  • ❌ Don’t hide assets — this can escalate to civil or criminal issues


🧠 Can You Still Qualify for an Offer in Compromise?


Yes — but the IRS will closely scrutinize your finances.


If you:

  • Have limited assets or equity
  • Can show negative cash flow
  • Have no luxury spending or asset transfers


…then you may qualify to settle for a fraction of what you owe, or even pause enforcement on large debts due to hardship until your situation improves.

👉 How Much Will the IRS Usually Settle For?


📊 Large Case IRS Thresholds


When your debt is over $100,000:

  • You’re flagged for Field Collection
  • You may deal with a Revenue Officer (not just Automated Collections)
  • IRS may file a lien automatically
  • Passport restrictions can apply if the debt exceeds $62,000 (adjusted for inflation)
