Quick overview

A CP2000 is not an audit notice; it’s a proposed change based on information the IRS received. Foreign-sourced income—wages, dividends, interest, rental receipts, or pension payments earned outside the U.S.—often creates mismatches because of differing reporting rules, foreign statements, or missing FATCA/FBAR filings. (See IRS: Understanding Your CP2000 Notice.)

Step-by-step response (practical)

  1. Read the notice carefully. Note the tax year, the items the IRS shows, the proposed tax change, and the response deadline (typically 30 days). (IRS: Understanding Your CP2000 Notice)
  2. Compare line by line. Match the IRS’s listed items to your filed Form 1040 and attached schedules (Schedule B, Schedule E, etc.).
  3. Gather documentation. For each foreign amount, collect paystubs, bank statements, broker statements, pension statements, contracts, or foreign tax assessments. If the documents aren’t in English, get a certified translation.
  4. Determine the correct treatment:
  • Was the income already reported but on a different line or form? (Common when foreign dividends or interest are omitted from Schedule B or Form 8938.)
  • Is the income excludable under the foreign earned income exclusion (Form 2555) or offset by a foreign tax credit (Form 1116)?
  • Does a tax treaty apply? If so, get the treaty article and supporting proof.
  1. Decide how to respond:
  • Agree: sign the response, pay the balance, or set up a payment plan.
  • Disagree: provide a clear, itemized explanation and attach supporting documents.
  • Need to amend: if the correct fix is a changed return, prepare Form 1040‑X and attach statements proving the change. (See our guide on [How to Prepare and File an Amended Return Correctly].)
  1. Mail or upload your response per the notice instructions. Keep copies of everything you send.

Evidence checklist (what the IRS wants to see)

  • Foreign paystubs, employer statements, or contract
  • Bank or broker statements showing deposits and account currencies
  • Year-end statements (foreign equivalents of 1099/1098)
  • Proof of foreign tax paid (for Form 1116) or proof of FEIE eligibility (Form 2555)
  • Copies of FBAR (FinCEN Form 114) or Form 8938 if filed
  • Translations and a cover letter explaining discrepancies

Common scenarios and recommended fixes

  • Missing foreign bank interest or dividends: amend or provide proof that you reported them on Schedule B/Form 8938 or claim the correct foreign tax credit.
  • Foreign pension or annuity not reported: verify U.S. taxability, then amend to include the income or provide treaty documentation.
  • Payments routed through foreign intermediaries (freelancers, contractors): collect invoices and bank receipts; show where you reported the income.

Timing, penalties, and interest

Respond by the deadline—usually 30 days—to avoid automatic assessment. If you agree to an additional tax, interest and penalties can apply from the original due date of the return. If you need more time, call the phone number on the notice and request an extension, but don’t ignore the notice.

When to involve a professional

Foreign income rules and treaty issues can be complex. In my practice, taxpayers who bring clear documentation to a CPA or international tax advisor typically resolve CP2000 notices faster and with fewer surprises. Consider hiring a tax professional experienced with FBAR/FATCA issues if the notice involves multiple years or large amounts.

Practical tips

  • Put the CP2000 number and tax year on every page you submit.
  • Provide a simple summary at the front: what you’re sending and why it fixes the notice.
  • Keep originals and send copies by certified mail or upload via the IRS portal when available.

What if you ignore it?

Ignoring a CP2000 can lead to the IRS assessing additional tax, plus penalties and interest, and could eventually escalate enforcement. Always respond—even if only to ask for time to gather documents.
