What Is an IRS Audit?
An IRS audit is a review of your tax return by the Internal Revenue Service to ensure that your income and deductions are reported accurately. It doesn’t necessarily mean you’ve done something wrong—sometimes returns are selected at random or due to mismatched information. The goal is to ensure compliance with federal tax laws.
Types of IRS Audits
- Correspondence Audit: Done through mail; typically requests more documentation for specific deductions.
- Office Audit: You visit an IRS office to clarify parts of your tax return.
- Field Audit: An IRS agent visits your home or business for a deeper investigation.
Common IRS Audit Triggers
There are certain red flags that can increase the likelihood of an audit. Here’s what you should be aware of:
1. **High Income
** While everyone can be audited, those with higher incomes tend to be scrutinized more. According to IRS data, the audit rate increases significantly for taxpayers earning over $200,000 annually.
2. Large Charitable Deductions
If your charitable deductions are disproportionately large compared to your income, it may raise suspicion. The IRS knows the average range of donations per income level and flags any returns that fall well outside the norm.
3. Home Office Deduction
Claiming a home office can trigger an audit, especially if you deduct a large percentage of your home expenses. The space must be exclusively used for business, not a shared living space.
4. Unreported Income
The IRS gets copies of all your W-2s and 1099s. If you forget to report even one of them, it can lead to an automatic audit.
5. Excessive Business Expenses
If you’re self-employed and your business reports a lot of expenses that seem high relative to your income, the IRS may take a second look. Especially watch for large travel, meals, or entertainment deductions.
6. Claiming the Earned Income Tax Credit (EITC)
This credit is often abused, so claiming it—especially if you have complex income—can lead to more scrutiny.
7. Cash Businesses
If you operate a business that deals largely in cash (like a restaurant or salon), you’re more likely to be audited. The IRS knows these businesses can underreport income more easily.
8. Mathematical Errors
Simple mistakes in math or incorrectly transferring data can prompt an audit. The IRS uses automated systems that easily detect these errors.
9. Rental Losses
Claiming losses from rental properties when you don’t qualify as a real estate professional can draw attention.
10. Foreign Accounts and Income
Failing to report foreign bank accounts or income is a major red flag. You must file an FBAR (Report of Foreign Bank and Financial Accounts) if your total foreign account balances exceed $10,000.
How the IRS Selects Returns for Audit
Understanding how returns are chosen can help you stay compliant:
1. Computer Scoring (DIF System)
The IRS uses a system called the Discriminant Information Function (DIF), which assigns a numeric score to each return. Higher scores signal potential problems and are more likely to be audited.
2. Random Selection
Sometimes returns are selected entirely at random as part of compliance research.
3. Related Audits
If your business partner, employer, or investor is being audited, your return could be selected too.
How to Avoid an IRS Audit
While there are no guarantees, here are ways to reduce your audit risk:
1. Report All Income
Don’t forget 1099s or side income. Cross-check your W-2s, 1099s, and bank statements before submitting your return.
2. File Electronically
Electronic filing software reduces mathematical errors and ensures more accurate returns.
3. Use Professional Tax Help
A certified public accountant (CPA) or enrolled agent can help ensure your return is error-free and compliant.
4. Keep Detailed Records
Save receipts, invoices, and records that back up every deduction or credit you claim. You may never need them, but if audited, they’ll be essential.
5. Be Conservative with Deductions
Avoid inflating deductions or business expenses. Use reasonable and well-documented figures.
6. Double-Check Math
Even if you file electronically, review your numbers before submitting. Typos and miscalculations are easy to catch ahead of time.
7. Avoid Amending Returns Unnecessarily
Amending your return too often can draw attention. Make sure your original return is accurate.
8. Report Cryptocurrency Transactions
The IRS is taking digital currency seriously. Report any crypto sales, exchanges, or income honestly.
What to Do If You’re Audited
Getting audited doesn’t mean you’re in trouble—it just means the IRS wants more info. Here’s how to handle it:
1. Stay Calm
Don’t panic. Most audits are minor and involve sending in documents.
2. Read the Notice Carefully
The IRS will specify what part of your return they are examining and what documents they need.
3. Respond Promptly
You’ll have a deadline. Missing it can result in penalties.
4. Organize Your Records
Provide only what is asked for. Organize receipts and forms clearly.
5. Consider Hiring a Professional
A CPA or tax attorney can represent you during the audit and help you navigate the process.
IRS Audit Red Flags: Quick Checklist
| Red Flag | Why It Matters |
|---|---|
| High income | Higher chance of being selected |
| Mismatched 1099 or W-2 | IRS already has this info; discrepancies stand out |
| Large charitable donations | Must match your income level |
| Overstated deductions | Especially for travel, meals, home office |
| Home office deduction misuse | Must meet strict exclusive-use criteria |
| Early withdrawals from retirement | Can create tax complications |
| Claiming dependents inaccurately | Shared custody often results in duplicate claims |
Common IRS Audit Myths
Myth 1: Only the Rich Get Audited
While high earners face a higher audit rate, people of all income levels can be audited.
Myth 2: You Can’t Be Audited After You Get a Refund
The IRS has up to three years to audit your return, even if your refund was already issued.
Myth 3: Filing Early Prevents Audits
Filing early is good for many reasons, but it doesn’t impact audit risk.
Myth 4: A CPA Guarantee Means No Audit
Even if a professional prepares your return, you can still be audited.
IRS Audit Statistics
To understand how common audits are, consider the following data:
- Less than 1% of all tax returns are audited each year
- People earning under $200,000 have a 0.2% chance of being audited
- Returns with errors or mismatches have a much higher audit risk
How Long Should You Keep Tax Records?
The IRS generally has three years from the date you filed to audit your return. But if they suspect fraud or a major understatement of income, they can go back up to six years. Keep these records:
- Tax returns: At least 3–7 years
- W-2s and 1099s: 3–7 years
- Receipts and deductions: 3–7 years
- Property records: Until the property is sold, plus 3 years
When to Seek Help
If you’re unsure about your tax return, consult a professional, especially if:
- You have multiple sources of income
- You’re self-employed
- You own rental properties
- You’ve made large donations
- You’re being audited
Final Thoughts
No one wants to deal with the stress of an IRS audit. While you can’t eliminate the risk entirely, understanding what triggers an audit and how to file an accurate, honest tax return can greatly reduce your chances. Be organized, stay within reasonable deduction limits, and keep thorough records.
