Before you panic — most IRS letters are routine and resolvable. The two things that actually matter are knowing exactly what type of notice you received and hitting the real deadline printed on it. Stout Tax Strategies reviews the letter, identifies what's actually being asked, and handles the response so the deadline doesn't pass while you're still figuring out what CP2000 even means.
First, check this: Look at the top-right corner of your letter for the notice or letter number (e.g., "CP2000," "CP14," "Letter 566"). Then find the response deadline — usually stated clearly in the first paragraph. These two details determine everything about what happens next. If you can't find either, send us a photo and we'll identify it within one business day.
IRS correspondence isn't one thing — it's dozens of different notice types, each requiring a different response. Here are the ones we handle most often for Macomb County clients:
| Notice/Letter | What It Means | Typical Deadline |
|---|---|---|
| CP2000 | Income reported by employers/banks/brokers doesn't match your return. A proposed change, not a final bill. | 30 days (60 if outside the U.S.) |
| CP14 | You have an unpaid balance. First notice in the IRS collection sequence. | 21 days to pay or arrange a plan |
| CP3219A | Notice of Deficiency — follow-up when a CP2000 goes unanswered. Final step before assessment. | 90 days to petition Tax Court |
| CP22A | Confirms the IRS has assessed changes you agreed to or didn't dispute. | Payment due as stated on notice |
| Letter 566 / Letter 525 | Formal audit notice requesting documentation for specific deductions or credits. | Varies — stated on letter, often 30 days |
| CP501 / CP503 / CP504 | Escalating collection reminders for an existing balance. CP504 signals intent to levy. | Immediate attention recommended |
| LT11 / Letter 1058 | Final Notice of Intent to Levy — your right to a Collection Due Process hearing. | 30 days to request a CDP hearing |
Notice numbers appear in the top-right corner of the letter. If yours isn't listed here, send it to us and we'll identify it.
2026 IRS guidance. General information — review your specific notice for the deadline that applies to you.
The IRS contacts taxpayers by mail first — almost never by phone, email, or text for a first contact. Check the return address and notice number against the official IRS notice index at irs.gov/notices. Scam letters often mimic real notice formatting.
The deadline is calculated from the date printed on the letter, not the day you opened the envelope. Mail delays of several days are common. If the notice references a 30-day window and arrived a week after it was dated, you have less time than you think.
Silence is treated as agreement. If you don't respond to a CP2000 within the window, the IRS assesses the proposed changes, adds penalties, and starts collection. Disagreeing requires a response — ignoring it does not protect you.
Send us a photo of the letter. We identify the notice type, the actual deadline, and explain in plain language what the IRS is asking for and why — typically within one business day.
We request your IRS wage & income and account transcripts directly, so we know exactly what the IRS has on file before drafting any response — not guessing based on what you remember.
Agree, partially agree, or dispute — we prepare the appropriate response form and supporting documentation, and submit it before your deadline. For CP2000s, this means the official response form plus a written explanation if disputing.
Letter 566 and similar audit requests specify exact documents needed. We translate the request, gather the records, and prepare them in the format examiners expect.
If penalties were already assessed, we evaluate First-Time Penalty Abatement (available with a clean 3-year compliance history) and reasonable-cause arguments for the accuracy-related penalty.
For CP501/503/504 and Final Notices of Intent to Levy (LT11/Letter 1058), we help evaluate payment plan options and, where applicable, request a Collection Due Process hearing before the 30-day window closes.
Photo, scan, or in-person — however is easiest. We identify the notice type and real deadline, usually within 24–48 hours.
We pull your IRS transcripts to see exactly what triggered the notice, then identify what supporting documents you need.
We draft the response — agreement, partial agreement, or formal dispute — and submit it before the deadline, by mail or fax as the notice requires.
IRS processing typically takes 60–120 days after a response is filed. We track the case and confirm closure or escalation with you directly.

One thing specific to Michigan: a federal CP2000 adjustment often triggers a parallel notice from the Michigan Department of Treasury once the federal change posts. We handle both together so the figures match and the responses don't contradict each other.
It depends on the notice type. Most proposed-change notices like CP2000 give 30 days (60 if you live outside the U.S.). Balance-due notices like CP14 typically give 21 days. A Notice of Deficiency (CP3219A) starts a separate, non-extendable 90-day window to petition Tax Court. The exact deadline is always printed on your specific notice.
For a CP2000, missing the deadline means the IRS treats the proposed changes as accepted, assesses the tax, adds an accuracy-related penalty (commonly around 20%), and interest continues accruing daily. For collection notices, missing deadlines can escalate to liens or levies. Responding late is still generally better than not responding — contact us even if a deadline has passed.
No. Some IRS letters simply confirm a correction made in your favor, verify identity for processing, or provide informational updates that require no action. The notice itself will state whether a response is needed. When in doubt, have it reviewed — acting on a letter that needed no response costs nothing; ignoring one that did can be expensive.
Real IRS notices arrive by mail, reference a specific notice number matching the official IRS index at irs.gov/notices, and never demand immediate payment via gift card, wire transfer, or cryptocurrency. The IRS doesn't initiate contact by email or text demanding personal information, and doesn't threaten immediate arrest. If anything feels off, call the IRS directly at 800-829-1040 to verify — never use a number printed only on the suspicious letter.
Often yes. First-Time Penalty Abatement is available if you have a clean 3-year compliance history, regardless of whether the underlying tax adjustment was correct. Separately, the accuracy-related penalty can sometimes be challenged on reasonable-cause grounds. We evaluate both for every case.
Simple notices — like one confirming a math correction in your favor — often need no professional help. Notices involving income discrepancies, audits, or balances due benefit from professional review, since the response format matters and a poorly drafted dispute can result in the proposed changes being accepted by default. We offer a free initial review to tell you which category your notice falls into.
Start with the notice itself and the tax return for the year referenced. If you have related documents — W-2s, 1099s, brokerage statements — include those too. If you're missing documents, we can pull your IRS wage and income transcript directly to see what the IRS has on file.
