Audits Are on the Rise — But Fear Isn’t a Strategy

In 2025, the Internal Revenue Service is undergoing its most aggressive enforcement push in over a decade. With new funding from the Inflation Reduction Act, enhanced data analytics, and a renewed mission to close the tax gap, the IRS is auditing more individuals and small businesses than at any time in recent memory. 

But here’s the truth: 

An audit doesn’t have to mean panic. 

 With the right documentation, representation, and mindset, it’s possible to resolve audits quickly — and even come out ahead. 

At Riley & Company CPA, we’ve helped dozens of clients successfully navigate IRS audits, CP2000 notices, and underreporting challenges. In this guide, we’ll show you what triggers audits in 2025, how to prepare in advance, what to do (and not do) if you’re selected, and how we defend your interests every step of the way. 

PART I: Why IRS Audits Are Increasing in 2025

Let’s start with why the audit climate is different this year: 

💰 1. Increased IRS Funding = More Enforcement 

The Inflation Reduction Act earmarked $80 billion for IRS improvements over 10 years. While some of that funding has been adjusted, it has already enabled: 

  • Hiring thousands of new revenue agents and auditors 
  • Upgrading audit selection algorithms using AI and big data 
  • Expanding audit coverage to small businesses, gig workers, and crypto investors 
 

💡 Translation: The audit net is wider, and it’s casting faster. 

📊 2. Better Data Matching and Automation 

The IRS now automatically matches: 

  • 1099-K and 1099-NEC income to reported earnings 
  • Form 1099-DA (crypto) to Schedule D 
  • Schedule C and F claims to statistical norms 
  • Foreign bank account reports (FBARs) and Form 8938 to W-2 wages 
 

This data matching leads to CP2000 notices — automated “soft audits” requesting clarification or correction. 

🔍 3. Focus Areas for 2025 

IRS audits this year are focusing on: 

  • Self-employed individuals and sole proprietors 
  • High Schedule C deductions or net losses 
  • Gig workers and 1099 earners 
  • ERC refund claims (for employers) 
  • Cryptocurrency and digital asset sales 
  • Payroll tax compliance and worker classification 
 

Whether you’re a consultant, shop owner, or side hustler, you are on the radar. 

PART II: What Triggers an IRS Audit (or CP2000 Notice)

Understanding common red flags can help you stay out of the crosshairs. Here are the top triggers: 

🚩 1. Income Mismatch 

Failing to report income that’s been reported to the IRS via: 

  • 1099-K 
  • 1099-NEC 
  • W-2 
  • Brokerage statements 
  • Crypto exchanges 
 

The IRS’s systems automatically issue CP2000 notices when these don’t line up. Even small mismatches can trigger letters. 

🚩 2. High or Unusual Deductions 

While deductions are legal and encouraged, excessive or poorly documented deductions may raise red flags: 

  • Home office: must be exclusive and regular 
  • Meals and travel: must be ordinary, necessary, and business-related 
  • Charitable donations: large gifts without documentation are a red flag 
  • Business mileage: estimates are not acceptable — you need logs 
 

We help clients document deductions in ways that withstand IRS scrutiny. 

🚩 3. Repeated Business Losses 

If your Schedule C shows losses for 3 consecutive years, the IRS may reclassify your activity as a hobby — disallowing deductions entirely. 

🚩 4. Excessive Credits or Refund Claims 

Claiming: 

  • The Earned Income Tax Credit 
  • The American Opportunity Credit 
  • ERC (Employee Retention Credit) 
 

…without substantiation may trigger review — especially in 2025, as these are under heightened audit. 

PART III: How to Prepare for an Audit — Even Before You’re Notified

The best audit defense begins before the IRS ever contacts you. 

📁 1. Keep Thorough Documentation 

You must keep records for at least 3 years, and in some cases up to 7 years. 

Recommended records include: 

  • Invoices and receipts for all income 
  • Bank statements and canceled checks 
  • Business mileage logs (use apps like MileIQ) 
  • Expense documentation (date, amount, business purpose) 
  • Copies of W-2s, 1099s, and prior year returns 
  • Contracts, leases, and payroll records 
  • Cryptocurrency transaction histories and wallet addresses 
 

💡 Tip: Use digital apps like Dext, Expensify, or QuickBooks to maintain audit-ready files. 

📅 2. Conduct an Annual “Pre-Audit” Review 

We offer mid-year and year-end reviews to: 

  • Catch red flags early 
  • Verify deductions are supported 
  • Compare reported income vs. third-party forms 
  • Estimate potential liabilities or audit exposure 
 

Our goal is to eliminate surprises before the IRS notices anything. 

🧮 3. Understand Your Return — Even if You Use a Preparer 

Many taxpayers blindly sign returns without reviewing them. That’s risky. If audited, you are responsible, not just your preparer. 

We ensure every client understands their: 

  • Income sources and totals 
  • Deductions and rationale 
  • Supporting documentation 
  • Refund or payment drivers 
 

PART IV: What To Do If You Receive an IRS Letter or Audit Notice

Not all IRS letters are audits. But all of them must be taken seriously. 

📬 Step 1: Don’t Panic — But Don’t Ignore It 

Most IRS letters are time-sensitive, giving you 30 to 90 days to respond. 

  • Ignoring a notice can result in automatic assessments, liens, or garnishments 
  • Responding correctly can resolve the issue with minimal disruption 

🔍 Step 2: Verify It’s Real 

IRS scams are rampant. Look for: 

  • Official IRS logo 
  • Your full name and address 
  • notice number (e.g., CP2000, LT11) 
  • Clear request for information — never threats 

Still unsure? Call us. We verify notices at no cost. 

📑 Step 3: Gather Documentation and Respond Promptly 

If the notice involves: 

  • Missing income → Gather 1099s, bank records 
  • Disallowed deductions → Provide receipts, logs, or written explanations 
  • Audit → You’ll receive a letter with specific requests and a deadline 

We help draft and submit professional responses, minimizing back-and-forth and avoiding costly errors. 

👨‍💼 Step 4: Hire Representation 

Whether it’s a CP2000 or a full-blown audit, you don’t have to go it alone. 

As your CPA, we can: 

  • Respond directly on your behalf 
  • Present organized, persuasive documentation 
  • Negotiate penalties or payment plans 
  • Appeal unjust assessments 
  • Represent you during in-person or field audits 

This takes the stress, confusion, and emotion off your plate.
