What to Do If You Receive an IRS Notice
Receiving a letter from the IRS can feel intimidating. Many people assume the worst when they see an official envelope arrive in the mail. In most cases, however, an IRS notice is simply the beginning of a conversation between the taxpayer and the government.
The most important step is to read the notice carefully. IRS letters typically explain the reason for the communication, what action may be required, and the timeframe for responding. Ignoring the notice can cause a relatively small issue to become a larger problem.
Common Reasons for IRS Notices
Taxpayers may receive IRS correspondence for many reasons, including:
- Missing or incomplete information on a tax return
- A discrepancy between reported income and third-party documents such as W-2s or 1099s
- Questions about deductions or credits claimed
- Payment issues or balances owed
- Requests for additional documentation
Many notices are informational and can be resolved by providing clarification or documentation.
A notice proposing changes because your return does not match a W-2 or 1099, such as a CP2000 notice, is not a bill, but it does need a reply by its due date.
Do Not Panic
An IRS notice does not automatically mean an audit or investigation. In many cases, the IRS is simply requesting information or proposing a small adjustment.
However, responding properly is important. Deadlines included in the notice must be respected, and the response should be accurate and well documented.
If the letter follows an audit and proposes changes you disagree with, it may be an IRS 30-day letter, which sets a short deadline to request an appeal. A notice of deficiency is different again: it generally gives you 90 days to go to the U.S. Tax Court, and that deadline cannot be extended. A final notice of intent to levy carries the right to a Collection Due Process hearing if you ask within 30 days.
When Legal Guidance May Help
If a notice involves a significant amount of tax, multiple years of returns, or the possibility of penalties, professional guidance may be helpful. An experienced tax attorney can review the notice, evaluate the government’s position, and determine the most effective response.
Taking the First Step
Receiving an IRS notice can be stressful, but it is often manageable when addressed promptly and carefully. Understanding the issue and responding thoughtfully can prevent the matter from escalating.
