Delinquent International Information Return Submission Procedures (DIIRSP): IRS rules for 2026
As of 2026, the IRS Delinquent International Information Return Submission Procedures is still a live compliance path for taxpayers who missed certain international information returns, are not under IRS civil exam or criminal investigation, and have not already been contacted by the IRS about those delinquent forms.
In practice, this lane works best when the missed filing is the information return itself, not unreported foreign income or unpaid tax. If your facts also involve missed foreign income, compare the IRS Streamlined Filing Compliance Procedures and the IRS Delinquent FBAR Submission Procedures before you file.
The following 4 takeaways matter most in 2026:
- DIIRSP is still available, but it is narrow. It is meant for delinquent information returns such as Forms 5471, 5472, 8865, 8938, 3520, 3520-A, or 926 when the filing facts fit this lane.
- Penalty relief is NOT automatic. The IRS says penalties may still be assessed under existing procedures, even when a reasonable-cause statement is attached.
- The IRS also says your attached reasonable-cause statement may NOT be considered during initial processing. You may need to defend that statement later in response to an IRS notice.
- DIIRSP does not replace other offshore options. If you missed FBARs, omitted foreign income, or have willfulness risk, another path may be safer.
If you want help sorting the right compliance lane before you file, you can contact TFX through their streamlined filing procedure service for overdue offshore filings.
What is IRS Delinquent Information Return Submission Procedures (DIIRSP)?
The IRS delinquent information return submission procedures are a narrow catch-up method for late international information returns. They are designed for late forms, not for fixing unpaid tax, omitted income, or facts that suggest willful noncompliance.
Under the current IRS DIIRSP page, taxpayers file delinquent international information returns through normal filing procedures. For delinquent international information returns other than Forms 3520 and 3520-A, the IRS says to attach the late form to an amended income tax return and file it under the amended-return instructions. Forms 3520 and 3520-A follow their own current filing instructions. For individuals, that amended return is often Form 1040-X.
This is why our guide to IRS tax amnesty programs for expats treats DIIRSP as one lane inside a larger decision tree. The key question is not only which form was missed, but whether the missed filing came with unpaid tax, unreported foreign income, FBAR issues, or facts that make non-willfulness hard to defend.
Based on a TFX client scenario: A US engineer in Germany owned 12% of a local company and had already reported $18,400 of salary and dividend income on timely filed US returns for 2023 through 2025. The missing items were Form 5471 and Form 8938, so the issue was the information reporting itself, not unpaid tax.
Is DIIRSP still available in 2026?
Yes, the IRS Delinquent International Information Return Submission Procedures page remains active on IRS.gov and shows a last-reviewed date of November 25, 2025.
What changed is not availability but emphasis. The current IRS delinquent information return submission procedures say penalties may still be assessed under existing procedures, and it specifically warns that an attached reasonable-cause statement may not be considered during initial processing.
That means the delinquent international information return submission procedures IRS page is no longer read safely as “file late and move on.” A better reading for 2026 is: file correctly, attach strong, reasonable cause where appropriate, and be ready to answer later correspondence if the IRS assesses a penalty anyway.
If an IRS notice arrives 6 to 12 months later, having the exact version of the instructions you relied on can help you respond faster.
If the IRS has already contacted you, this is usually no longer the right lane.
Who qualifies for DIIRSP?
Eligibility is narrow, and at least 3 IRS official gates plus 1 practical screening question should all point the right way. If any one of them breaks the wrong way, the delinquent information return submission procedures may not be your safest option.
The following 4 conditions should be met before you use DIIRSP (the first 3 are the IRS official gates):
- You are not under an IRS civil examination.
- You are not under an IRS criminal investigation.
- You have not already been contacted by the IRS about the delinquent international information returns.
- Your problem is the late information return itself, not a broader offshore noncompliance issue involving omitted income, unpaid tax, or willfulness risk.
That last point matters because the IRS separates compliance lanes. Streamlined is built for taxpayers who failed to report foreign financial assets and pay all tax due but certify non-willfulness, while CI Voluntary Disclosure is aimed at willful conduct.
NOTE! DIIRSP is usually a poor fit when foreign income was omitted, tax is still owed, or the facts could look deliberate.
In those situations, if you are perhaps, an accidental American who needs to catch up, you should check our guide for better starting points.
Which forms can be filed under DIIRSP?
DIIRSP commonly shows up with 7 core international information returns, and the penalty spread is wide. A missed Form 8938 may start at $10,000, while Form 5472 starts at $25,000, and continuation penalties can keep climbing.
Key takeaway: DIIRSP is commonly used for late information returns, but not every form files the same way. Forms 3520 and 3520-A follow their own filing instructions, while Forms 5471, 5472, 8865, 8938, and 926 are commonly attached to an amended return or the return type that should have included them.
| Common form | What it reports | Typical expat or business trigger | Usual penalty exposure | Commonly seen with amended returns? |
|---|---|---|---|---|
| Form 3520 | Foreign trusts, certain foreign gifts, certain distributions and ownership reporting | Large foreign gift, foreign trust transfer, foreign trust distribution | Often greater of $10,000 or 35% for Parts I or III; greater of $10,000 or 5% for Part II; Part IV foreign gift penalty can reach 5% per month up to 25% | Usually, no – follow Form 3520 filing instructions |
| Form 3520-A | Annual reporting for a foreign trust with a US owner | Foreign grantor trust with a US owner | Greater of $10,000 or 5% of the US owner’s share of trust assets | Usually no – filed under Form 3520-A rules or as a substitute attached to Form 3520 |
| Form 5471 | Certain ownership and activity in a foreign corporation | US shareholder, officer, or director tied to a foreign corporation | $10,000 initial penalty, then $10,000 every 30 days after 90 days, up to $50,000 continuation penalty | Often yes |
| Form 5472 | Reportable transactions between a reporting corporation and foreign or domestic related parties | Foreign-owned US corporation, foreign-owned US disregarded entity, related-party transactions | $25,000 initial penalty, then $25,000 every 30 days after 90 days with no stated maximum | Often yes, usually with Form 1120 or pro forma Form 1120 |
| Form 8865 | Interests in certain foreign partnerships, transfers, acquisitions, or changes | Controlled foreign partnership, transfer to a foreign partnership | Often $10,000 initial penalty plus continuation penalties up to $50,000; some transfer failures can trigger 10% of FMV, capped at $100,000 unless intentional disregard | Often yes |
| Form 8938 | Specified foreign financial assets | Expats abroad over $200,000 end-of-year or $300,000 anytime if single, or $400,000 / $600,000 if joint | $10,000 initial penalty, then $10,000 every 30 days after 90 days, up to $50,000 continuation penalty | Often yes |
| Form 926 | Certain transfers of property to a foreign corporation | Transfer of stock, securities, cash, or other property to a foreign corporation | Often 10% of FMV, capped at $100,000 unless intentional disregard | Often yes |
How to file delinquent international information returns under DIIRSP
The filing mechanics matter as much as the eligibility test, and at least 7 steps should be completed in order. A technically correct form filed the wrong way can still create penalties and processing problems.
The following 7 steps should be completed before you submit a DIIRSP package:
- Identify every missing form and every affected year. Start by matching the missed international return to the tax year that originally required it. Use the current IRS forms, instructions, and publications page and the relevant form instructions, not an old checklist.
- Confirm whether income was already reported and tax already paid. If foreign income was omitted or extra tax is due, pause and compare DIIRSP against Streamlined or Voluntary Disclosure before filing.
- Prepare each delinquent form completely. A substantially incomplete form can be treated as unfiled, which defeats the point of the submission.
- Use the correct filing vehicle for the form. For many forms other than 3520 and 3520-A, this means attaching the delinquent form to an amended return. For individuals, that often means Form 1040-X; for corporations and partnerships, use the amended-return process that matches the original return type.
- Attach a separate reasonable-cause statement for each delinquent form when you are asserting reasonable cause. Do not use one vague paragraph to cover multiple forms, multiple years, and multiple facts.
- Mail or file to the correct place shown in the current instructions. Forms 3520 and 3520-A are the classic exception because they follow their own instructions instead of the usual amended-return path.
- Keep proof of filing and a full duplicate set. Save signed copies, mailing receipts, tracking, and the final reasonable-cause statements for every year involved.
For individuals, Form 1040-X is often the amended return used in this process, but not every case requires a 1040-X. But the correct filing vehicle depends on the original filer and return type.
The IRS’s DIIRSP page says delinquent international information returns other than Forms 3520 and 3520-A should generally be attached to an amended income tax return and filed under the applicable amended-return instructions, while Forms 3520 and 3520-A follow their own filing instructions.
What should a DIIRSP reasonable-cause statement include?
A strong, reasonable-cause statement is fact-specific, chronological, and supported. The IRS reasonable-cause standard focuses on whether you exercised ordinary business care and prudence but still failed to comply.
The following 5 elements should appear in most DIIRSP reasonable-cause statements:
- What happened. State the exact form, year, and filing duty that was missed.
- Why the failure occurred despite ordinary business care and prudence. Explain the facts, not your conclusion.
- When you discovered the problem. A dated timeline helps the IRS understand whether you acted promptly after discovery.
- What corrective steps you took. State when you gathered records, prepared the missing forms, and filed them.
- Why the facts do not suggest tax evasion or deliberate concealment. Keep this factual and restrained.
Supporting documents can matter. Good attachments often include prior preparer emails, trust statements, corporate records, brokerage statements, passport or residence records, medical documentation, and anything else that helps prove the timeline.
Weak statements are risky because they sound interchangeable. “I did not know,” “my preparer missed it,” or “the rules were confusing” is usually not enough unless you explain exactly what you knew, what you relied on, what records you had, and why the failure persisted.
Can penalties still apply under DIIRSP?
Yes. The current DIIRSP IRS guidance says penalties may still be assessed under existing procedures, and your attached reasonable-cause statement may not be considered during initial processing.
The following 4 penalty points should shape how you use DIIRSP:
- A late filing under DIIRSP is not a guaranteed penalty waiver.
- The IRS may assess penalties during processing before it evaluates your reasonable-cause explanation.
- Once an IRS notice is mailed, continuation penalties can start after 90 days for forms such as 5471, 5472, 8865, 8938, 3520, and 3520-A, depending on the form.
- If a penalty is assessed, you may need to answer IRS correspondence, dispute the penalty, or seek abatement later.
Recent IRS penalties pages are especially useful here because they lay out the current penalty math form by form. That makes it much harder in 2026 to treat DIIRSP as an informal “amnesty” program.
TFX client scenario: A dual citizen in Canada had already reported $26,700 of foreign investment income on US returns but had missed Form 5472 for a foreign-owned US LLC with related-party transactions. The filing issue looked fixable, but the $25,000 starting penalty meant the reasonable-cause package had to be drafted with far more care than a simple late attachment.
DIIRSP vs Streamlined Filing vs Delinquent FBAR Procedures vs Voluntary Disclosure
There are 4 main offshore correction lanes, and the right one depends on two questions:
- Was income omitted?
- Is willfulness a real risk?
If you answer those two questions wrong, you can file into a lane that does not actually solve your problem.
Key takeaway: DIIRSP is the narrowest lane. Streamlined filing compliance procedure covers 3 years of tax returns and 6 years of FBARs for non-willful cases with income issues. Delinquent FBAR procedures cover FBAR-only problems where income was already reported and paid, and CI Voluntary Disclosure is the main lane for willful or high-risk facts.
| Compliance path | When to use | Income omitted? | FBAR issue? | Willfulness risk | Penalty profile | What gets filed |
|---|---|---|---|---|---|---|
| DIIRSP | Late international information return, no IRS contact, no exam, problem is the missed form itself | Usually no | Not the main issue | No formal non-willfulness certification | No automatic waiver; penalties may still be assessed and reasonable cause may need to be defended later | Delinquent information returns, often with amended returns; 3520/3520-A under their own instructions |
| Streamlined Foreign Offshore Procedures | Non-willful offshore noncompliance for qualifying taxpayers abroad | Yes, often | Often yes | Must be non-willful | Generally 0% miscellaneous offshore penalty if eligible | 3 years of delinquent or amended returns, 6 years of FBARs, certification |
| Streamlined Domestic Offshore Procedures | Non-willful offshore noncompliance for qualifying taxpayers in the US | Yes, often | Often yes | Must be non-willful | 5% miscellaneous offshore penalty | 3 years of amended returns, 6 years of FBARs, certification |
| Delinquent FBAR Submission Procedures | Missed FBARs only or primarily, with tax properly reported and paid | No | Yes | Low | IRS says no FBAR penalty if conditions are met | Delinquent FBARs filed electronically with late-filing explanation |
| CI Voluntary Disclosure Practice | High-risk facts, potential willfulness, or conduct that could be seen as deliberate | Often yes | Often yes | Higher | Penalties are expected; designed for willful cases | Disclosure application plus amended or delinquent returns and reports |
What if you missed FBARs or foreign income too?
If your facts go beyond the late information return, DIIRSP may no longer be the best fit. In 2026, the biggest branching rule is simple: FBAR-only issues point one way, missed income points another way, and possible willfulness points a third way.
The following 3 branches usually control the next step:
- If the issue is missed FBARs only and the related income was already reported, and tax paid, Delinquent FBAR Submission Procedures may fit.
- If the issue includes unreported foreign income and you can certify non-willfulness, Streamlined may fit better.
- If the facts could look willful, incomplete, or intentionally concealed, CI Voluntary Disclosure is usually the safer lane to evaluate first.
This is why DIIRSP should not be treated as a catch-all offshore cleanup tool. It is one lane in the broader IRS options framework, not a substitute for every late foreign filing problem.
Common DIIRSP mistakes to avoid
Most DIIRSP problems come from 6 predictable filing mistakes, not from obscure law. That is good news because most of them are avoidable before anything is mailed.
The following 6 mistakes should be avoided:
- Using DIIRSP when foreign income was omitted, or additional tax is due.
- Attaching vague, generic, one-size-fits-all reasonable-cause language.
- Failing to include a separate statement for each delinquent form and year where reasonable cause is asserted.
- Confusing FBAR filing with DIIRSP and assuming one fixes the other.
- Filing incomplete forms or leaving schedules out because the data feels burdensome.
- Assuming late filing automatically means penalty relief.
A seventh mistake is using stale instructions. Always start with the current IRS forms, instructions, and publications page, and then verify the specific form instructions before you file.
When to get professional help with Delinquent International Information Return Submission Procedures
Professional help is worth considering when the facts create penalty exposure above the usual “late attachment” problem. Once multiple forms, foreign entities, or trust structures are involved, the risk of choosing the wrong lane can easily exceed the cost of getting the filing strategy right.
The following 6 situations usually justify getting professional help before self-filing:
- You missed multiple forms across multiple years.
- You own a foreign corporation or foreign partnership and the filing set includes Forms 5471, 5472, 8865, or 926.
- You already received an IRS notice or any contact related to the missing filing.
- You may have omitted foreign income or still owe additional tax.
- Your facts involve a foreign trust, large foreign gifts, or substitute Form 3520-A issues.
- You are not fully confident you can defend non-willfulness or reasonable cause.
The practical benefit is not only form preparation. It is picking the right compliance path before a wrong filing closes off better options or triggers avoidable notices.

Delinquent International Information Return Submission Procedures FAQ
This delinquent international information return submission procedures FAQ answers 8 short questions people search for in 2026. It is also the fastest way to compare DIIRSP IRS rules against Streamlined, Delinquent FBAR, and Voluntary Disclosure at a glance.
Yes. The IRS DIIRSP page is currently live on IRS.gov, and the page shows a last-reviewed date of November 25, 2025, and the delinquent international information return submission procedures remain available for qualifying late information-return cases.
No. The DIIRSP IRS page says penalties may still be assessed under existing procedures, and the IRS may not consider your attached reasonable-cause statement during initial processing.
Usually that is a warning sign that DIIRSP may not be the right lane by itself. If the problem includes unreported foreign income or unpaid tax, review Streamlined or Voluntary Disclosure first.
No. FBARs follow a separate track through the Delinquent FBAR Submission Procedures or another offshore option if income was also missed.
Common DIIRSP forms include Forms 3520, 3520-A, 5471, 5472, 8865, 8938, and 926. The filing mechanics differ by form, so always check the current form instructions.
That is usually where the fit breaks down. One of the main eligibility screens is that you have not already been contacted by the IRS about the delinquent information returns.
Sometimes, but not always. Individuals often use Form 1040-X for forms that should have been attached to an income tax return, while Forms 3520 and 3520-A follow their own filing rules and business returns may require a different amended-return path.
You may need to answer the notice, provide or resubmit your reasonable-cause explanation, dispute the penalty, or request abatement. This is why a copy of the full filing package and proof of submission should always be saved.
