That envelope from the IRS triggers an immediate stress response. Heart rate increases. Worst-case scenarios flood the mind. Many Buford residents let IRS notices sit unopened for days, dreading what might be inside.

Here’s a perspective shift worth considering: most IRS notices aren’t emergencies. The majority inform recipients of minor adjustments, request simple clarification, or provide routine account updates. Understanding what different notices mean transforms scary mail into manageable correspondence.

This guide explains the IRS notice system—what different notice types mean, which ones demand immediate attention, and how to respond appropriately. Buford residents who understand these communications can address issues calmly and effectively rather than letting problems compound through avoidance.

How the IRS Notice System Works

The IRS sends notices for specific reasons, and each notice type has a designated number (like CP2000 or LT11). These numbers indicate exactly what the notice addresses and what response, if any, is required.

Notice numbers starting with “CP” typically address issues with filed returns—math errors, missing payments, account adjustments. Numbers starting with “LT” usually relate to collection activities. Letters may request information, propose changes, or demand action.

Every notice includes a “Notice Date” and usually a response deadline. These deadlines matter. Missing them can escalate routine issues into serious problems.

The IRS sends notices by mail to the last address on file. This is one reason keeping address information current with the IRS is important. Notices sent to old addresses still trigger deadlines and consequences, even if the recipient never sees them.

Common Information Notices (No Action Required)

Some notices simply provide information. They don’t demand response or indicate problems.

CP21A, CP21B, CP21C, CP21E

These notices inform taxpayers that the IRS adjusted their account—usually in the taxpayer’s favor. Perhaps the IRS found an additional credit, corrected an error, or processed an amended return.

What to do: Review the notice to understand what changed. If the adjustment seems correct, file the notice with tax records. No response is necessary unless the adjustment appears incorrect.

CP49

This notice explains that the IRS applied an overpayment (refund) to another tax debt. Instead of receiving a refund check, the money went toward a balance owed.

What to do: Verify that the debt existed and the amount applied was correct. If questions arise about the underlying debt, address those separately. The CP49 itself just explains the allocation.

CP521

Monthly reminder for taxpayers on an installment payment plan, showing the payment amount due and due date.

What to do: Make the payment on time. Keep the notice as a record.

Notices Requesting Response or Clarification

These notices require action within specified timeframes—usually 30-60 days.

CP2000

One of the most common notices. The IRS received information from third parties (employers, banks, brokerages) that doesn’t match what appeared on the tax return. This triggers an automated notice proposing adjustments to income and tax owed.

What to do: Review the notice carefully. Compare the reported income against personal records. Sometimes the discrepancy results from:

  • Duplicate reporting of the same income
  • Income already reported under a different form
  • Legitimate deductions the IRS doesn’t know about
  • Actual unreported income that needs to be addressed

Respond within the deadline—typically 30 days. If the IRS is correct, payment can be made or a payment plan requested. If the IRS is wrong, documentation proving the correct treatment should be submitted.

Ignoring CP2000 notices results in automatic assessment of the proposed changes, plus penalties and interest.

CP501, CP503, CP504

These form the standard collection notice sequence for unpaid taxes:

  • CP501: First reminder that taxes remain unpaid.
  • CP503: Second reminder. More urgent tone.
  • CP504: Intent to levy notice. This means the IRS may seize assets, bank accounts, or wages to collect the debt.

What to do: Address the underlying debt before reaching CP504 status. Payment in full is ideal. If full payment isn’t possible, contact the IRS to establish a payment plan before levy actions begin.

CP75

The IRS needs additional documentation to verify items on the return—often the Earned Income Tax Credit (EITC), which has high audit rates due to frequent errors and fraud.

What to do: Gather the requested documentation and respond by the deadline. This might include proof of income, residency, or relationship to qualifying children. Failure to respond results in denial of the claimed credit.

Serious Notices Requiring Immediate Attention

Some notices indicate situations that require prompt, careful response.

LT11 (Final Notice of Intent to Levy)

This notice represents one of the last steps before the IRS takes collection action. It indicates that previous notices were sent and the debt remains unpaid.

What to do: Act immediately. Options include:

  • Paying the balance in full
  • Establishing an installment agreement
  • Requesting Currently Not Collectible status if financial hardship exists
  • Pursuing an Offer in Compromise to settle for less than owed
  • Filing an appeal if you disagree with the underlying tax assessment

Waiting until assets are actually seized makes resolution more difficult. Respond before the deadline—typically 30 days.

CP90 or LT1058 (Final Notice Before Levy – Federal Tax Lien)

Similar to LT11 but specifically addresses the filing of a federal tax lien. A lien attaches to all property owned and damages credit significantly.

What to do: Consider the same options as LT11. Additionally, if circumstances changed since the debt arose (job loss, medical emergency, etc.), professional assistance may help negotiate better terms.

Letter 1058

Final notice before the IRS levies wages, bank accounts, or other assets. Not a bluff—the IRS follows through on these.

What to do: Immediate action required. Contact the IRS or a tax professional before the deadline. Once a levy executes, reversing it becomes much harder.

CP2501

The IRS believes income was underreported and is requesting verification before making changes. This is the precursor to CP2000—a chance to explain before adjustments occur.

What to do: Respond with documentation supporting the original return positions. Effective response at this stage can prevent CP2000 issuance entirely.

Audit Notices

Audit notifications deserve special attention and often benefit from professional representation.

Letter 525 (General 30-Day Letter)

Proposes changes based on an examination and gives 30 days to agree, provide additional information, or request an appeal.

Letter 566 (Correspondence Audit)

Requests specific documentation to verify items on a tax return. These audits happen through mail rather than in-person meetings.

What to do for audit notices: Gather requested documentation carefully. Respond within deadlines. Consider whether professional representation would be beneficial—particularly for complex returns or significant proposed changes.

How to Respond to IRS Notices

Effective responses share common characteristics:

Respond by the deadline. Every notice includes a response date. Missing it eliminates options and can automatically trigger adverse actions.

Keep copies of everything. Copy the notice, all response documents, and proof of mailing. Certified mail with return receipt provides evidence that the response was sent.

Be specific. Reference the notice number, tax year, and taxpayer identification number. Address exactly what the notice requested—no more, no less.

Include documentation. Assertions without support don’t change IRS positions. Proof changes outcomes.

Follow up if no response is received. If 8 weeks pass without acknowledgment, contact the IRS to verify receipt. Sent is not the same as received.

When to Get Professional Help

Some situations benefit from professional representation:

  • Audit notices for complex returns
  • Significant proposed tax increases
  • Collection notices (CP504, LT11, Letter 1058)
  • Any notice that feels confusing or overwhelming
  • Situations where previous IRS interactions didn’t resolve issues

Tax professionals communicate with the IRS on behalf of clients, understand procedural options, and often achieve better outcomes than self-representation—particularly in collection and audit situations.

Key Takeaways

  • Open IRS mail immediately. Avoiding notices doesn’t prevent deadlines from passing.
  • Check the notice number. It indicates exactly what the notice addresses.
  • Respond by the deadline. Missing deadlines escalates minor issues into serious problems.
  • Document everything. Keep copies of notices and responses permanently.
  • Get help for serious notices. Collection actions and audits often warrant professional representation.

Conclusion

IRS notices are communications, not convictions. Most can be addressed through straightforward responses—providing documentation, correcting misunderstandings, or establishing payment arrangements.

The key is action, not avoidance. Buford residents who address IRS notices promptly prevent small issues from becoming large problems. Those who ignore notices find themselves facing levies, liens, and collection actions that could have been avoided.

Understanding what different notices mean removes the mystery and reduces the fear. Not every notice requires panic—but every notice requires attention.
