Curious about how far back the IRS can do an audit? While most taxpayers are safe after three years, certain mistakes or omissions can extend your audit risk to six years, or even indefinitely in cases of fraud or unfiled returns. Knowing these timelines, your rights, and when to seek professional help can save you from years of financial stress and costly disputes.
Read along to know more about how far back the IRS can do an audit.
Understanding IRS Audit Statute of Limitations
The statute of limitations is an authorized period during which the IRS can scrutinize your taxes.
- The Legal Basis: The law 26 U.S.C. 6501 sets a time limit, usually three years, from when you file your tax return for the IRS to audit your taxes, ensuring both the IRS and taxpayers have a clear, fair timeline.
- What It Does: This law gives the IRS a specific time frame to audit your taxes, allowing enough time for proper checks and also setting a clear deadline after which your tax years are considered closed.
- Why You Should Care: If you aren’t sure how long to keep records or when you are officially out of the woods, this IRS investigation period can give you the answer.
The Standard 3-Year Audit Window
The rule applies to most of the taxpayers: the IRS usually has a return period of three years.
The 3-Year Rule: IRS can start an audit within 3 years of when you submitted your return or when taxes are due, whichever occurs later.
Example:
If you already filed your 2022 tax returns on April 15, 2023, the IRS will ideally be given a window of April 15, 2026, to reach out to you to audit that year.
Understanding When the Audit Clock Starts
It is necessary to know when the three-year audit window opens up. This is how it is done:
The “Later Of” Rule: The later of two dates begins to run the audit clock:
- Official due date (the general one is April 15th)
- The day that you filed your tax return
Late Filing Example: If you filed your 2021 return on June 1, 2022, the three-year countdown begins on June 1, 2022.
These timelines can help you stay informed and prepared when it comes to tax audits.
IRS Internal Guidelines: The 26-Month Rule
Although the law allows the IRS three years to complete an audit, they usually try to finish much faster.
- Internal Goal: The guidance issued by the Internal Revenue Manual (IRM) requires the agents to attempt to conclude and initiate the audits within 26 months after the date of filing.
- Purpose: His internal deadline means the IRS must complete their audit within three years, but you still have time to appeal or ask for reviews beyond that period.
- Modern Reality: Due to backlogs, this 26-month target isn’t always met, but it remains the agency’s goal for most routine cases.

Extended Audit Periods: When the IRS Can Go Back 6 Years
Sometimes, the answer to how far back the IRS can do an audit is longer than three years. However, in some cases, the IRS can look back six years if you make major errors, like leaving out more than 25% of your income.
- Substantial Underreporting: You failed to report over 25 percent of your gross earnings.
- Foreign Assets: You never disclosed foreign financial assets worth more than $5,000.
- Basis Overstatement: You greatly overstated the cost basis of property, and this led to understating your income.
Substantial Income Underreporting (25% Rule)
This is the most common reason for a six-year audit window.
- The Threshold: In case you had failed to report an income that totals over 25 percent of the gross income you have reported, the IRS possesses a period of six years to audit.
Example:
You earned $120,000 but only reported $80,000. The $40,000 omission is more than 25% of $80,000, triggering the six-year rule.
- Intent Doesn’t Matter: This happens even when the omission was due to an unintentional mistake.
Foreign Asset Reporting Violations
The IRS is cracking down on unreported offshore accounts.
- The Rule: Failing to report foreign assets worth more than $5,000 can open you up to a six-year audit.
- What Counts: This includes foreign bank accounts, investments, and other financial interests that should be reported on forms like the FBAR or Form 8938.
Basic Overstatement Issues
This often happens with sales of property, stock, or business assets.
- What It Is: Usually, it is what you paid for an asset.
- The Trigger: If you report your income is too low by more than 25%, the IRS can audit you for up to six years.
Unlimited Audit Periods: When There’s No Time Limit
In the most serious cases, the answer to how far back the IRS can do an audit is forever. There is no statute of limitations for these situations.
- Tax Fraud: You filed a false or fraudulent return with the intent to evade tax. The IRS can audit that year at any time in the future.
- Unfiled Returns: You didn’t file a tax return at all. The audit clock never starts, leaving you permanently exposed for that year.
- Invalid Returns: You filed a return but didn’t sign it. The IRS considers an unsigned return to be an unfiled return.
How Long Does an IRS Audit Take to Complete?
Once an audit starts, you’ll naturally wonder how long an IRS audit takes. The duration varies widely by type.
| Audit Type | Typical Start | Typical Length |
| Correspondence | Within 7 months of filing | 3–6 months |
| Office | Within 1 year of filing | 3–6 months |
| Field | Within 1 year of filing | 6–12 months or more |
Correspondence Audits: 3-6 Months
This is the most common and least intimidating type of audit.
- How It Works: The entire audit is handled through the mail. The IRS sends a letter asking for more information or documentation on a specific issue.
- Timeline: Usually initiated within 7 months of filing and resolved in 3 to 6 months.
- Key to Success: Responding promptly and completely can help you close the case quickly.
Office Audits: 3-6 Months
This audit requires an in-person meeting.
- How It Works: You (or your representative) bring your records to a local IRS office to meet with an auditor.
- Timeline: The process typically takes 3 to 6 months.
- Potential Delays: The timeline can extend if you need more time to find documents or if the auditor finds new issues to review.
Field Audits: 6-12 Months or More
This is the most comprehensive type of audit.
- How It Works: An IRS agent visits your home, business, or accountant’s office to conduct a thorough review of your books and records.
- Timeline: These are the longest audits, often lasting 6 to 12 months, and sometimes stretching for years if the case is very complex or involves a large business.
Factors That Affect Audit Timeline and Scope
Several factors affect how long an IRS audit takes and how detailed it is, including the type of audit, the complexity of your tax return, your cooperation, the IRS workload, and whether there are disputes or penalties involved.
- Scope Creep: An audit that starts with one issue can expand if the agent finds other potential problems. For example, a question about charitable donations could lead to a review of your business expenses.
- Your Response Time: Prompt, complete, and organized responses help shorten the audit. Delays on your end will always extend the timeline.
- Document Availability: If your records are neat and accessible, the audit will move smoothly. If they are missing or disorganized, expect delays and more questions.

- Privacy: To have your information kept confidential.
- Appeal: To appeal an IRS decision in an independent forum.

- Be Precise: Provide only the documents requested for the specific year under audit.
- Let a Pro Handle It: Have your representative (like one of our IRS audit attorneys) manage all communication with the agent to keep the audit focused.
Consensual Extensions and Strategic Considerations
The IRS may ask you to sign a form to extend the statute of limitations.
Fixed-Date vs. Open-Ended Extensions
- Fixed-Date Extension (Form 872): Extends the deadline to a specific date. This gives you more control and certainty.
- Open-Ended Extension (Form 872-A): Extends the deadline indefinitely until either you or the IRS formally ends it. This is generally riskier for the taxpayer.
When to Refuse Extensions
Refusing an extension can be best when you’re confident in your case and want to avoid delays or extra problems. Sometimes, not giving an extension is more helpful :
- The taxpayers already have all the required documents and information with the IRS.
- The taxpayer is faced with a time-sensitive request that ought to be settled in a quick manner.
- One thing that worries the taxpayer is the changes that might occur in the tax laws/regulations.
Strategic Considerations for Extensions
When considering whether or not to agree to an extension, various strategic considerations should be taken into account:
- Time Limits: A time limit is available under which extensions may be granted. In the case of individual taxpayers, extensions are usually required to be applied.
- Strategic Advantage: If the statute of limitations is about to expire and you feel the IRS has no case, refusing an extension may force them to close the audit.
- Consult an Expert: This is a strategic choice that should be referred to an expert. Never do anything without talking to your tax professional.
State-Specific Considerations and Variations
State tax audits and timelines vary from federal rules. For Georgia, working with a local expert like Hall’s IRS helps handle both federal and state audits smoothly.
- State Audits: Your state’s tax agency can also audit you.
- Different Timelines: States have their own statutes of limitations, which may be longer or shorter than the IRS’s.
- Interaction: A federal audit can trigger a state audit, and vice versa. For Georgia residents, it’s wise to consult a local expert like Hall’s IRS, who understands both federal and Georgia tax audit rules.
Conclusion:
Ultimately, how far back the IRS can do an audit depends on your specific situation. The three-year rule applies to most taxpayers, but making a big mistake may stretch it to six years, and there is no time limit to fraud or failure to file.

Frequently Asked Questions
Q1. Can the IRS audit me after 10 years?
That is very rare, but yes. If you had committed fraud in terms of tax, had never filed a tax return, or had filed a tax return unsigned, you have no limit as to when the IRS would audit you. Otherwise, in most cases, 3-6 years.
Q2. What triggers the IRS to extend an audit beyond 3 years?
The primary causes include underreporting gross income by over 25 percent or non-reporting of certain foreign financial resources that are in excess of $5,000 in foreign-based assets. This makes the audit window stand at six years.
Q3. How can I tell if my audit will take longer than normal?
Red flags of an extended audit are: it is a field audit (on your business), the audit extends to a series of tax years where the IRS believes serious problems have occurred, or you have big, complicated transactions.
Q4. Does hiring an attorney make my audit take longer?
Not by a jot. If a case is handled by experienced IRS audit attorneys, the resolution may actually be accelerated in a number of situations. They are aware of the ways to successfully interact with the IRS, present their records in an organized way, and negotiate a resolution more effectively.
Q5. What happens if the statute of limitations expires during my audit?
Suppose the statute of limitations runs, and you have not consented to its extension. In that case, the IRS can not impose any more tax on you in that year. This is why whenever an audit is taking too long, the IRS will virtually request an extension.
