DIIRSP: IRS Pathways After Missing International Information Returns (Reasonable Cause—Careful Framing)

Author: Chenchen Liu, CPA ｜ YCL Tax, Accounting & Advisory

Bottom line in one breath

If you are a Cary / RTP taxpayer who later discovers possible missed Forms 5471, 8865, 8938, 3520, and similar international information returns, the IRS page on Delinquent International Information Return Submission Procedures (often called DIIRSP) describes filing through normal procedures when you are not under civil examination, not under criminal investigation, and have not already been contacted by the IRS about those delinquent information returns. This is a filing-path description, not a penalty amnesty. The IRS states that penalties may still be assessed under existing procedures, and that an attached reasonable-cause statement may not be considered during initial processing—you may need to respond later. Forms 3520 / 3520-A have a special note that reasonable-cause statements are considered before assessment. Whether Streamlined or Voluntary Disclosure fits instead is facts-specific. This article is compliance planning only and guarantees no penalty relief.

Background

The IRS international-taxpayer page explains how to submit delinquent international information returns: forms other than 3520 / 3520-A are generally attached to an amended income-tax return; Forms 3520 / 3520-A follow their own instructions. The same page lists Criminal Investigation Voluntary Disclosure Practice and Streamlined filing compliance procedures as other offshore options. For Chinese-American clients, gaps often surface when buying a home, reviewing equity, documenting parental transfers, or hiring a cross-border CPA for the first full checkup. Pause for pathway selection before “just filing this year’s form.”

Old vs. new (path vs myths)

1. Myth: “Late filing = automatic penalty waiver.” IRS text: penalties may still be assessed.

2. Myth: “One reasonable-cause letter ends it.” IRS: the statement may be ignored in processing; later correspondence may be required.

3. 3520 / 3520-A exception: reasonable-cause review before assessment; mark the first page “Reasonable Cause Statement attached.”

4. Submission vehicle: most information returns → with an amended return; 3520/3520-A → per their instructions (often separate).

5. Vs Streamlined: a different compliance framework (often discussed with non-willfulness and tax-due elements)—not interchangeable without analysis.

6. Vs Voluntary Disclosure (CI): a different risk posture and process.

7. Exam risk: amended filings are not automatically audited but remain subject to ordinary selection.

Self-check: does this affect you?

1. You suspect prior-year gaps on 5471 / 8865 / 8938 / 3520, etc.

2. You believe you are not under related exam/CI contact about those delinquencies (facts control).

3. You are unsure whether income tax was also under-reported, or whether conduct could be viewed as willful.

4. You are weighing “information returns only” versus broader correction programs.

5. You want one coordinated inventory rather than piecemeal patches.

Simplified example (illustration only—not a recommended path or promised outcome)

Assume Mr. Zhao in RTP is a U.S. tax resident who wholly owns a China company and never attached Form 5471:

1. Scenario A: income returns largely complete; main gap is information reporting; facts suggest non-willful omission → practitioners may discuss normal delinquent filing as described on the DIIRSP page plus per-form reasonable-cause narratives—yet IRS may still assess penalties first. No waiver guarantee.

2. Scenario B: multi-year unfiled returns or clear omitted foreign income → Streamlined or other options may need evaluation; do not default to “5471 only.”

3. Scenario C: IRS has already contacted you about the missing international forms or an exam has begun → the “file through normal procedures” premise may no longer fit; get professional help immediately.

Different facts → different moves; a blog cannot choose for you.

Action timeline

1. Now: stop scattershot fixes; matrix forms, years, entities, accounts.

2. Risk screen: exam/CI status, willfulness indicators, tax-due gaps (high level).

3. Compare pathways in writing—DIIRSP-described normal filing vs Streamlined vs other—without oral guarantees.

4. If filing delinquencies: prepare the amended package or standalone 3520 package per IRS instructions; attach a separate, chronological reasonable-cause statement per return when asserting reasonable cause (mark 3520 as instructed).

5. After filing: keep proof of delivery; watch notices; if penalties assess, respond through the notice process. Delay usually worsens posture.

FAQ

Q: Does DIIRSP guarantee no penalties?

A: No. The IRS expressly says penalties may still be assessed under existing procedures. Treat any “guaranteed waiver” claim as unreliable.

Q: Are reasonable-cause statements useless then?

A: They can still matter for later relief. The IRS warns they may not be considered in initial processing (with a pre-assessment note for 3520/3520-A). Whether reasonable cause is accepted is facts-specific.

Q: Can I use Streamlined and DIIRSP together?

A: Do not stack frameworks on your own. They are different regimes; eligibility requires a full-facts professional review.
