Quick overview

Receiving an IRS letter or notice is common and usually manageable if you track the correspondence from the moment it arrives. In my practice helping taxpayers for over 15 years, the clients who avoid escalation are those who treat every letter as actionable until proven otherwise. The IRS primarily sends notices by U.S. mail (not email), and each notice includes a code and response instructions — preserve that letter and act promptly (IRS: “Understanding Your IRS Notice or Letter”) (https://www.irs.gov/individuals/understanding-your-irs-notice-or-letter).

Why tracking IRS correspondence matters

  • Deadlines matter. Many notices have explicit deadlines for reply, payment, or appeal. Missing a deadline can increase penalties or speed enforcement.
  • Evidence matters. Tracking preserves a timeline and proof of your responses (copies, certified-mail receipts, scans, notes of phone calls).
  • Prioritization matters. Not all notices require the same action — a balance-due notice is higher priority than an informational acknowledgement.

How the IRS typically sends notices

The IRS normally mails notices and letters to the address on file; they will not send taxpayers unsolicited tax-related requests via email or text asking for payment or immediate personal data (see IRS guidance on common scams). For account-specific details you can view your account at the IRS Online Account portal (https://www.irs.gov/payments/view-your-tax-account) to confirm whether a mailed notice matches the IRS records (IRS: “View Your Account”).

First steps when you receive a notice

  1. Read the notice carefully. Note the notice code, issue date, and any response deadline.
  2. Do not ignore it. Even a notice that looks informational can include steps you must take to preserve rights.
  3. Make a complete scan or photograph of the letter (front and back) and save it to a secure location.
  4. Log the notice immediately in your tracking system (see tracking template below).

A practical tracking system (spreadsheet or simple database)

Set up a single file—either a spreadsheet, a tax-management app, or a small case-management database—to record every notice. Suggested columns:

  • Tax year
  • Date received (scan filename date)
  • Notice code (e.g., CP2000, CP14) and short description
  • Issue date (on the notice)
  • Required action (pay, submit docs, call, etc.)
  • Response deadline (calculated from notice issue date)
  • Assigned owner (you, CPA, attorney)
  • Response method (mail, e-file, phone)
  • Proof of response (filename or tracking number)
  • Status (open / responded / resolved / escalated)
  • Notes (phone call time, rep name, case ID)

Example spreadsheet row:

Tax year Date received Notice code Required action Deadline Owner Status
2023 2025-03-12 CP2000 Provide wage docs or agree to adjustments 30 days from issue CPA Responded 2025-04-08 (scanned proof)

Tools and technology to use

  • Scanning and cloud storage: Scan every physical letter and store it in an encrypted folder (Google Drive or Dropbox with 2FA). Keep the scanned file name consistent (YYYY-MM-DDNoticeCodeLastName.pdf).
  • Calendar reminders: Add at least two calendar alerts (one at two weeks before deadline and one at five days) in Google Calendar or Outlook.
  • Mail tracking for responses: When you respond by mail, send documents via certified mail with return receipt or use a carrier with tracking numbers and keep the receipt.
  • IRS Online Account: Use the IRS online account to confirm notices and check payment history (https://www.irs.gov/payments/view-your-tax-account) (see IRS online account for account history and certain notice details).
  • Payment tools: If a notice requires payment, use secure IRS channels—Direct Pay, Electronic Federal Tax Payment System (EFTPS), or debit/credit payment portals listed on IRS.gov (https://www.irs.gov/payments).

Verifying legitimacy and avoiding scams

Notices can be spoofed. Before you act, verify legitimacy:

Prioritizing common notices

Common notices and typical priorities (general guidance only):

  • CP2000 (proposed changes to return because of income mismatch): High priority — respond within about 30 days with documentation or an agreement to the changes.
  • CP14/BALANCE DUE (balance due notice): High priority — pay or arrange a payment plan. The notice will list the due date and consequences for nonpayment.
  • Notices of Adjustment (acknowledgment of return changes): Medium priority — confirm or contest the adjustment.
  • Audit or Examination notices: Very high priority — gather records and consult your preparer or tax counsel.

For timelines and exact instructions, always follow the text on the notice and the IRS guidance at “Understanding Your IRS Notice or Letter” (https://www.irs.gov/individuals/understanding-your-irs-notice-or-letter).

How to respond and document your response

  • Draft a clear cover letter summarizing why you are responding and listing attachments.
  • Include copies of supporting documents, not originals, unless the notice specifically requests originals.
  • Mail your response via certified mail or use an overnight courier and keep the tracking number. Be sure to include a copy of the original notice or reference the notice code and date.
  • If you speak with the IRS by phone, record the date, time, name and badge number of the representative, and the callback number. Follow up in writing where possible and attach that follow-up to your case file.

When to escalate or get professional help

  • Complex audits, significant proposed assessments, or notices involving liens/levies merit immediate professional representation.
  • If you have tried to resolve a notice and cannot get a timely or reasonable result, contact the Taxpayer Advocate Service or consult a tax attorney or enrolled agent. In my practice, involving a professional early often prevents missed deadlines and missteps.

Record retention guidance

Keep IRS correspondence and related records according to IRS retention guidance: generally keep records for at least three years from the date you filed your return, and up to seven years for certain claims or losses (IRS: “Recordkeeping for Individuals”) (https://www.irs.gov/filing/individuals/recordkeeping). Keep notice-response records and proof of delivery until the matter is fully resolved plus the applicable statute of limitations.

Practical checklist to use right away

  • Step 1: Read and scan the notice immediately.
  • Step 2: Log notice details in your tracking file.
  • Step 3: Check IRS Online Account for matching activity (https://www.irs.gov/payments/view-your-tax-account).
  • Step 4: Set calendar reminders for deadlines.
  • Step 5: If required, gather supporting documents and send a documented response (certified mail or tracked courier).
  • Step 6: Log proof of response and update status until resolved.

Real-world example

A client received a CP2000 for an income mismatch. We logged the notice the same day, collected wage statements and a corrected attachment from a third-party payer, and responded with a cover letter and certified-mail proof within 18 days. Because we documented each step, the IRS corrected the match without penalties — the documented timeline made the difference in avoiding escalation.

Pro tips from practice

  • Never throw away the original notice until the issue is closed and the statute of limitations has expired.
  • Use consistent filenames and a single tracking spreadsheet so you never have to search multiple places for evidence.
  • If you mail a response, send only the documents the IRS requests and protect sensitive information (redact unrelated personal data).
