If you’re searching for audit defense near me, chances are you’ve received a notice from the IRS, California’s Franchise Tax Board (FTB), or the California Department of Tax and Fee Administration (CDTFA). And now you’re worried — rightfully so.

An audit can flip your life or business upside down.

But the key to surviving — and coming out ahead — is having a local expert who knows how to handle the agency, the paperwork, and the pressure.

In this blog, we’ll explain:



What Triggers an IRS or CDTFA Audit?


IRS Audits:


  • Income mismatch (e.g., 1099 not reported)
  • High deductions or credits vs. income
  • Unfiled returns
  • Claims that don’t match national averages (red flags)
  • Small business losses (Schedule C)


These cases often lead to an IRS audit assessment process where the agency recalculates your liability, adds penalties, and may enforce collection actions.


CDTFA Audits:


  • Underreported sales tax
  • Z-tape mismatches
  • POS system irregularities
  • Cash-heavy industries (restaurants, auto shops, nail salons)
  • 1099-K / credit card data mismatch


If you run a business, defending against CDTFA sales tax audits can mean the difference between a manageable adjustment and a crushing tax bill.


IRS vs. CDTFA Audits: What’s the Difference?

Feature IRS Audit CDTFA Audit
Focus Income tax Sales/use tax
Who’s audited Individuals + businesses Retail businesses
Documents requested 1099s, returns, deductions Sales records, POS, bank deposits
Tactics Correspondence or field audit On-site visits, extensive probing
Penalties Accuracy penalties, fraud Penalties + forced assessments
Timeline Slower Aggressive and fast-moving

Why "Audit Defense Near Me" Actually Matters


You could hire a national tax firm — but they’ll assign your case to someone who’s never seen a CDTFA audit in their life.


Local expertise means:


  • Understanding state-specific rules
  • Knowing which local CDTFA district office is handling your audit
  • Preparing documentation that matches what these agents actually ask for
  • Being able to show up (or Zoom in) with confidence and strategy
