Received an IRS Notice While Living Abroad? Don't Ignore It — You Have a Hard Deadline.
An IRS notice is not something you can put aside until it's convenient. Most notices carry a 60-day response window — and when that window closes, the IRS treats their proposed adjustments as final. Mark Anderson, CPA reviews your notice, identifies the correct response strategy, prepares the written reply, and handles all IRS communication on your behalf. 100% remote. 50+ countries served.
An IRS Notice Is Not an Audit — But It Is a Legal Deadline That Cannot Be Ignored
Most IRS notices sent to US expats are not audit notifications. They are automated correspondence from the IRS's matching systems, flagging a discrepancy between what was reported on your return and what the IRS received from a third-party source (a W-2, 1099, K-1, or foreign income report). The IRS calls this a CP2000 — a Proposed Changes to Your Tax Return notice — and it is the most common notice type expats receive.
A CP2000 is not a bill. It is not a demand. It is a proposal — and you have the legal right to agree, disagree, or partially dispute it within the stated deadline. The problem is that most people living abroad either don't receive the notice in time (mail forwarding delays are real), don't understand what it means, or assume ignoring it will make it go away. None of those outcomes ends well.
When the deadline passes without a response, the IRS automatically converts their proposal into a formal tax assessment. At that point, you owe the money — and the only way to contest it is through a more expensive, time-consuming appeals process. Mark Anderson, CPA handles IRS notice responses for expats in 50+ countries. Send him your notice — he tells you within one business day what it means, what you owe (if anything), and what the response strategy is.
The Deadline Is the Problem
Most IRS notices give you 60 days from the notice date — not from the date you received it. If mail forwarding added 3 weeks, your usable window may already be much shorter than 60 days. The Letter 531 (Notice of Deficiency) gives you only 90 days to petition the Tax Court. The CP90 (Final Notice of Levy) gives you 30 days before the IRS can seize assets. Act immediately.
Expats are overrepresented in IRS notice pools for several structural reasons:
→ Foreign income mismatches: Income excluded under the Foreign Earned Income Exclusion (Form 2555) appears on your employer's W-2 or 1099, but the IRS's automated matching system doesn't always cross-reference your Form 2555 exclusion correctly — so it flags the income as unreported.
→ Late or amended information returns: K-1s and 1099s are sometimes filed late by the issuer, arriving at the IRS after your return was processed. The system flags the discrepancy retroactively, sometimes years later.
→ Foreign address delay: The IRS mails notices to your last known US address. If mail forwarding isn't set up correctly, you may not receive the notice until after the deadline has passed — or not at all.
→ Prior year filing gaps: Expats who used the Streamlined Filing Procedure to catch up on back returns sometimes receive CP2000 notices for the caught-up years, because the IRS's records didn't previously include those returns.

- The IRS says you underreported income
- You received a notice about foreign bank accounts or FBAR

The IRS Notices Expats Receive Most — What Each One Means
Every IRS notice has a specific code printed in the top right corner. Here are the most common notices received by US expats — what they mean, how serious they are, and how much time you have to respond.
Don't see your notice code? The IRS has hundreds of notice types. If the code on your notice isn't listed here, send it to Mark — he reviews all IRS correspondence for expats. The code is printed in the top right corner of the first page, usually beginning with "CP," "LT," or "Letter."
Complete IRS Notice Response — What's Included in Every Engagement
Mark Anderson, CPA — US-licensed CPA with 15+ years of expat tax experience and a Fortune 500 corporate tax background — handles every aspect of your IRS notice response from review to resolution. You don't have to contact the IRS yourself. See our full pricing at the rates page.
Notice Review & Assessment
Mark reads the notice carefully and explains in plain language what the IRS is claiming, what the proposed adjustment is, what the deadline is, and whether the IRS's position is correct, partially correct, or incorrect. You get a clear picture within one business day of sending him the notice.
Return Reconciliation
Mark compares the IRS's claimed discrepancy against your filed return, your W-2s and 1099s, your Form 2555 (FEIE), Form 1116 (Foreign Tax Credit), and any other relevant forms — to pinpoint exactly where the IRS's matching system flagged an issue and whether the flag is accurate.
Written Response Preparation
Mark prepares the formal written response to the IRS — disputing incorrect adjustments with documentation, agreeing with correct ones, and providing any required explanation. The response is substantive, specific, and signed before sending. Generic template responses are not how IRS notices get resolved.
Documentation Assembly
Effective IRS responses require supporting documentation: copies of the relevant return, W-2s, 1099s, Form 2555, bank statements, or other evidence. Mark identifies exactly what documentation is needed for your specific notice and helps you locate and compile it, even from abroad.
IRS Correspondence Handled
If the IRS sends a follow-up after the initial response — additional information requests, partial agreements, or rejection of your position — Mark handles those follow-up communications too. You don't need to contact the IRS directly at any stage of this process.
Penalty Abatement Where Applicable
If the notice includes a penalty (such as the 20% accuracy-related penalty on a CP2000), Mark evaluates whether First-Time Abatement or Reasonable Cause relief applies — and includes an abatement request in the response where warranted. Paying a penalty that could be abated is never the right first move. See our penalty abatement page for details.
Why a Generic CPA Gets Expat IRS Notices Wrong — And What Mark Gets Right
Expat IRS notices have characteristics that domestic practitioners routinely misunderstand. The FEIE interaction with third-party income documents, the FBAR angle, the foreign tax credit reconciliation — these are not areas where a domestic CPA's template response is sufficient.
| Notice Response Area | Mark Anderson CPA | Generic Domestic CPA | DIY / No Response |
|---|---|---|---|
| Identifies FEIE mismatch as root cause of CP2000 | ✓ | ✗ Rarely recognized | ✗ |
| Cross-references Form 2555 exclusion against 1099 income | ✓ | ✗ | ✗ |
| Evaluates Foreign Tax Credit interaction with proposed adjustment | ✓ | ✗ | ✗ |
| Includes penalty abatement request where applicable | ✓ | Sometimes | ✗ |
| Handles from abroad — no US visit required | ✓ 100% remote | ✗ Requires US presence | ✓ But ineffective |
| Manages follow-up IRS correspondence | ✓ Included | Sometimes — extra charge | ✗ |
| Understands expat mail delay risk on deadlines | ✓ | ✗ | ✗ |
| Identifies if underlying return needs amendment | ✓ | Sometimes | ✗ |
The most expensive IRS notice mistakes are not made by ignoring the IRS. They are made by responding incorrectly — paying an inaccurate CP2000, agreeing to an adjustment that the FEIE should have covered, or responding without a penalty abatement request. Mark's review ensures you respond correctly the first time.

⚠️ Never pay a CP2000 without disputing it first if you believe it is incorrect or if you claimed the FEIE, a Foreign Tax Credit, or any exclusion that might explain the apparent mismatch. Paying an incorrect CP2000 is treated as acceptance of the IRS's position — reversing it afterwards requires a more complex amended return and refund claim process.
From Notice Receipt to IRS Resolution — The Process
Mark handles everything 100% remotely. You don't need to be in the US, call the IRS, or figure out what the notice means on your own. Here is the exact process, from the moment you contact Mark to the moment your notice is resolved. If you have missed prior years or unfiled returns that contributed to this notice, also explore the IRS Streamlined Filing Procedure — which may let you resolve the broader compliance issue simultaneously.
Send Mark Your Notice (Free — Today)
Take a photo or scan of the IRS notice and send it to Mark via the contact form, email, or WhatsApp. Include all pages of the notice. Mark reviews it within one business day and responds with a plain-language explanation of what the IRS is saying, how serious it is, and what your options are.
Free 30-Minute Consultation
Mark reviews the notice in detail, compares it to your filed return (you share the relevant year's return and supporting documents), identifies the source of the discrepancy, and confirms whether you agree, partially agree, or disagree with the IRS's proposed adjustment. He provides a flat-fee quote for the response work.
Documentation Gathering
Based on the notice type and the dispute strategy, Mark identifies the specific documentation needed — W-2s, 1099s, Form 2555, Form 1116, bank statements, or explanatory materials. He provides a clear checklist. Most expats have digital copies of the relevant documents already.
Written Response Preparation
Mark prepares the formal written response — addressed to the specific IRS office and notice number, referencing the relevant IRC sections, attaching the required documentation, and including a penalty abatement request where applicable. You review and sign the response before it is sent to the IRS.
Response Sent — Deadline Met
The response is mailed or faxed to the IRS with proof of delivery retained. Mark tracks the deadline and confirms submission was made within the required window. You receive a copy of everything sent.
IRS Follow-Up & Resolution
The IRS typically responds within 4–12 weeks with their decision — agreeing with your position (no change), accepting a partial adjustment, or maintaining their original position (which can be appealed). Mark handles all follow-up correspondence and advises on next steps if the IRS's initial response is unfavorable. For clients whose notice revealed underlying compliance gaps, Mark also handles the annual expat return going forward to prevent recurrence.
IRS Notice Questions Expats Ask Most Often
Direct answers to what Mark hears from US expats when they receive a letter from the IRS — from the moment of panic to the point of resolution.
A CP2000 is a Proposed Changes to Your Tax Return notice. The IRS received information from a third party — a W-2, 1099, K-1, or foreign income report — that does not match what appeared on your filed return, and they are proposing an adjustment to your tax, interest, and potentially a 20% accuracy-related penalty. A CP2000 is not a formal audit — it is an automated notice generated by the IRS's Automated Underreporter (AUR) program. However, it requires a written response within 60 days with supporting documentation, or the proposed adjustment becomes a formal assessment and collection proceedings begin.
You respond by sending a written reply — with supporting documentation — to the IRS address printed on the notice, within the stated deadline. For expats, the challenge is that the deadline clock starts from the notice date, not from the date you actually received it. Mail forwarding delays can eat into your window significantly. Mark handles IRS notice responses 100% remotely: you send him a photo or scan of the notice, he reviews it and prepares the written response, you sign it, and it is submitted to the IRS — all without you needing to contact the IRS yourself or be physically present in the US.
The most common reason: the IRS's automated matching system compares third-party income documents (W-2s, 1099s, K-1s) against your return, but does not always properly cross-reference the Foreign Earned Income Exclusion (Form 2555). Your employer reported income to the IRS, and the system flagged it as "unreported" because it didn't recognize the Form 2555 exclusion that offset it. This produces a CP2000 proposing additional tax on income you already reported and properly excluded — which can be fully resolved with a written response citing IRC Section 911 and attaching your Form 2555.
If you don't respond within the deadline, the IRS's proposed adjustment is automatically converted into a formal tax assessment. That means the IRS legally considers you to owe the proposed amount — whether or not it is correct. The IRS then sends a demand for payment, adds interest and penalties, and escalates to collection: federal tax lien, bank levy, or offset against future refunds or Social Security payments. For debts exceeding $62,000, the IRS can also certify the debt to the State Department for passport restriction. All of these consequences are avoidable with a timely response.
No. A CP2000 is not a formal audit (IRS examination). It is an automated correspondence notice from the IRS's Automated Underreporter (AUR) program, which runs a computer matching process comparing income documents against filed returns. An audit involves a human IRS agent examining your return in detail — a CP2000 is automated. However, ignoring a CP2000 and allowing it to escalate can eventually lead to a formal examination or to a Notice of Deficiency (Letter 531), which is a more serious enforcement action. Responding promptly to a CP2000 with clear documentation typically resolves it without any further escalation.
No — not without first verifying whether the IRS's position is actually correct. Paying a CP2000 is treated as agreement with the proposed adjustment. If the notice was triggered by a Foreign Earned Income Exclusion mismatch, a late 1099, or any other error in the IRS's matching process, paying the amount means you have overpaid. Recovering that overpayment requires a refund claim (Form 843 or amended return), which is a more complex, time-consuming process. Mark reviews your notice and your original return before recommending whether to pay, dispute, or partially agree — and includes an abatement request for any proposed penalties where grounds exist.
Letter 531 (Notice of Deficiency) — also called the "90-day letter" — is a formal statutory notice asserting you owe additional tax, typically following an examination or an unresolved CP2000. It gives you 90 days to either pay the deficiency or file a petition with the US Tax Court to contest it without paying first. If you do not respond within 90 days, the IRS assesses the tax automatically and begins collection — and you lose your right to challenge the amount in Tax Court without paying first. Letter 531 is significantly more serious than a CP2000 and should be reviewed by a tax professional immediately upon receipt.
Yes. Under the Fixing America's Surface Transportation (FAST) Act (IRC Section 7345), the IRS can certify "seriously delinquent tax debt" to the State Department, which can then revoke, limit, or decline to renew your US passport. The threshold for seriously delinquent debt is $62,000 in 2024 (adjusted annually). For expats who depend on their US passport for legal residency, work authorization, or travel in their host country, a passport revocation can have immediate and severe practical consequences. This is another reason why resolving IRS notices promptly — before tax debt compounds to this level — is critically important for Americans living abroad.
The IRS's automated matching system compares income documents filed by your employer or financial institutions against your return. If your employer filed a W-2 reporting your full salary, and your return shows that income excluded under the Foreign Earned Income Exclusion (Form 2555), the system sometimes flags this as a mismatch — because the automated pass doesn't always correctly cross-reference the Form 2555 exclusion applied to the same income. The response is straightforward: a written letter citing IRC Section 911, attaching a copy of your filed Form 2555, and explaining that the income was properly excluded. This type of CP2000 is resolved at the correspondence stage in most cases.
For a CP2000 with a clear, well-documented response, IRS resolution typically takes 6–12 weeks after the response is received. The IRS sends a follow-up letter confirming: (1) they agree with your position — no change, (2) they partially accept your position — reduced adjustment, or (3) they disagree and are maintaining the original proposal — which can be appealed. IRS response times vary significantly by volume. Mark monitors outstanding notice responses and follows up with the IRS if no response is received within the expected window.
It depends on how far past the deadline you are and what stage the IRS is at. If the deadline just passed, the IRS may still accept a late response — particularly with an explanation of why it was late (mail forwarding delay, foreign address, etc.). If the adjustment has been formally assessed, the options shift: filing an amended return (Form 1040-X) to correct the underlying issue, submitting a claim for refund (Form 843), or — if the assessment was very recent — filing an appeal. The worst option at any stage is to do nothing. Contact Mark as soon as you discover you've missed a deadline — earlier is always better.
