IRS Removes Old Section 4.01(22) Ruling Guidance: What the 2026 Changes Mean for International Taxpayers
The IRS’s annual update to its ruling procedures often receives little attention outside the tax community. However, Revenue Procedure 2026-7 contains an important procedural change that could affect taxpayers involved in cross-border transactions and international tax planning.
Contrary to the assumption that the IRS simply eliminated an outdated restriction, the 2026 update actually reflects a more nuanced shift. While the Service continues restricting advance rulings on many fact-intensive international tax matters, it simultaneously removed Section 4.01(22) from the list of issues for which rulings are ordinarily not issued. This change potentially expands opportunities for taxpayers seeking guidance on certain customs valuation and transfer pricing-related issues under Section 1059A.
At the same time, the IRS continues implementing major international tax reforms enacted under the One Big Beautiful Bill Act (OBBBA), making compliance, documentation, and tax modeling more important than ever.
Understanding Revenue Procedure 2026-7
Each year, the IRS publishes a revenue procedure outlining:
- Areas eligible for private letter rulings
- Areas eligible for determination letters
- Issues for which rulings ordinarily will not be issued
- Administrative procedures governing requests for guidance
These procedures help taxpayers determine whether advance IRS guidance is available before entering into significant transactions.
Revenue Procedure 2026-7 became effective January 5, 2026, and includes several important modifications affecting international tax matters.
What Changed in Section 4.01(22)?
One of the most overlooked changes involves the removal of former Section 4.01(22).
Historically, this provision generally identified Section 1059A issues as matters for which the IRS ordinarily would not issue rulings.
Section 1059A limits the tax basis or inventory cost that a taxpayer may claim for imported property acquired from a related foreign person to the amount declared for customs valuation purposes.
By removing Section 4.01(22) from the “ordinarily no-rule” list, the IRS has potentially expanded its willingness to consider ruling requests involving Section 1059A issues.
Why This Matters
The change may provide taxpayers with greater opportunities to obtain certainty regarding:
- Related-party import transactions
- Customs valuation issues
- Basis determinations
- Transfer pricing-related import structures
While rulings remain subject to general IRS requirements and factual limitations, the removal represents a notable procedural liberalization rather than an additional restriction.
Areas Where the IRS Still Refuses to Issue Rulings
Although Section 1059A issues may now be more accessible, the IRS continues maintaining strict no-rule positions in several international tax areas.
Examples include:
Permanent Establishment Determinations
The IRS generally will not rule on:
- Whether a taxpayer is engaged in a U.S. trade or business
- Whether a taxpayer has a permanent establishment in the United States
- Whether income is attributable to a permanent establishment
Manufacturing Determinations Under Section 954
The Service generally will not issue rulings regarding whether a product is manufactured for purposes of Foreign Base Company Sales Income under Section 954(d).
U.S. Possession Residency Determinations
The IRS also generally declines rulings regarding whether an individual qualifies as a bona fide resident of a U.S. possession.
These issues remain highly fact-dependent and must typically be analyzed without advance IRS approval.
OBBBA Reshapes the International Tax Landscape
The significance of the ruling procedure changes cannot be viewed in isolation.
The OBBBA fundamentally altered several core international tax provisions beginning in 2026.
GILTI Becomes Net CFC Tested Income (NCTI)
For tax years beginning after December 31, 2025:
- Global Intangible Low-Taxed Income (GILTI) is renamed Net CFC Tested Income (NCTI).
FDII Becomes FDDEI
Similarly:
- Foreign-Derived Intangible Income (FDII) becomes Foreign-Derived Deduction Eligible Income (FDDEI).
While these changes involve new terminology, they are accompanied by substantive modifications affecting international tax calculations.
Repeal of the Deemed Tangible Income Return Exclusion
One of the most significant OBBBA changes is the repeal of the deemed tangible income return exclusion.
Under prior law, taxpayers generally could exclude a deemed return based on certain foreign tangible assets from GILTI and FDII calculations.
Beginning in 2026:
- That exclusion no longer exists.
Why It Matters
The repeal broadens the amount of foreign income potentially subject to current U.S. taxation and may increase overall effective tax rates for multinational corporations.
Section 250 Deduction Changes
The OBBBA also modified the Section 250 deduction framework.
Net CFC Tested Income (NCTI)
Beginning in 2026:
- The deduction decreases from 50% to 40%.
Foreign-Derived Deduction Eligible Income (FDDEI)
Beginning in 2026:
- The deduction decreases from 37.5% to 33.34%.
These lower deduction percentages increase the amount of income potentially subject to U.S. tax.
How the New Section 250 Calculation Works
Taxpayers must now follow a revised calculation process.
Step 1: Determine Deduction Eligible Income (DEI)
Start with gross income and exclude:
- Subpart F income
- Net CFC Tested Income (NCTI)
- Foreign branch income
- Other statutory exclusions
In addition, gains from the sale of:
- Intangible property
- Depreciable property
- Amortizable property
- Depletion property
occurring after June 16, 2025, are generally excluded from DEI.
Step 2: Apply Deduction Allocation Rules
The OBBBA changed the expense allocation rules.
Importantly:
- Interest expense generally is not subtracted when determining DEI.
- Research and experimental (R&D) expenditures generally are not subtracted when determining DEI.
Step 3: Calculate Initial Deduction
Apply:
- 40% to NCTI
- 33.34% to FDDEI
Step 4: Apply the Taxable Income Limitation
If the total Section 250 deduction exceeds taxable income (computed without regard to Section 250), the deduction must be reduced accordingly.
This limitation can materially affect the final tax benefit available.
New Ownership Rules for CFC Shareholders
Another major 2026 change affects Subpart F and NCTI inclusions.
Under prior law, ownership on the last day of a CFC’s taxable year was often critical.
Beginning in 2026:
- Ownership during any day of the taxable year may trigger a pro rata inclusion.
Why It Matters
Taxpayers involved in:
- Stock acquisitions
- Corporate restructurings
- Partial ownership transfers
- Mergers and acquisitions
may face unexpected inclusions even if they do not own the stock on the final day of the year.
Repeal of the One-Month Deferral Election
The OBBBA also repealed the one-month tax-year deferral election for specified foreign corporations.
Beginning after November 30, 2025:
- Many specified foreign corporations must align their taxable year directly with their U.S. parent company.
In many situations, this creates a short tax year covering:
- December 1, 2025 through December 31, 2025
before transitioning to the aligned reporting period.
Compliance Considerations
Taxpayers should carefully model:
- Income allocations
- Foreign tax credits
- Earnings and profits calculations
- Reporting obligations
during the transition period.
Foreign Tax Credit Planning
International taxpayers must also consider revised foreign tax credit rules.
Deemed-Paid Credit Increase
For NCTI purposes:
- The deemed-paid foreign tax credit percentage increases from 80% to 90%.
New PTEP Limitation
A new 10% disallowance generally applies to foreign taxes associated with certain distributions of previously taxed earnings and profits (PTEP).
Proper modeling is necessary to determine the net benefit of these changes.
Estimated Tax and Penalty Considerations
The IRS continues emphasizing estimated tax compliance.
For corporations, estimated tax installments are generally due on:
- The 15th day of the 4th month
- The 15th day of the 6th month
- The 15th day of the 9th month
- The 15th day of the 12th month
Safe Harbor Rules
Generally, corporations avoid penalties by paying the lesser of:
- 100% of current-year tax, or
- 100% of prior-year tax
Large Corporation Limitation
Corporations with taxable income of $1 million or more in any of the preceding three years generally may only rely on the prior-year safe harbor for the first installment.
Accurate forecasting is therefore essential.
Planning Considerations for 2026
Taxpayers should review:
Section 1059A Transactions
Determine whether the expanded ruling availability provides an opportunity to obtain advance guidance.
NCTI and FDDEI Exposure
Model the impact of broader income inclusions and reduced Section 250 deductions.
Foreign Tax Credit Utilization
Evaluate how the revised credit rules affect global effective tax rates.
Ownership Changes
Assess whether revised pro rata share rules create unexpected income inclusions.
Tax-Year Alignment
Prepare for reporting changes resulting from the repeal of the one-month deferral election.
Final Thoughts
The 2026 update to IRS ruling procedures represents both a narrowing and an expansion of administrative guidance. While the IRS continues refusing rulings on many fact-intensive international tax issues, Revenue Procedure 2026-7 notably removes Section 1059A from the list of matters for which rulings are ordinarily unavailable. This may create new opportunities for taxpayers seeking certainty regarding related-party import transactions and customs valuation issues.
At the same time, the OBBBA’s sweeping reforms—including the transition to Net CFC Tested Income, revised Section 250 deductions, repeal of the deemed tangible income return exclusion, new ownership rules, and foreign tax credit modifications—require multinational taxpayers to perform more sophisticated tax modeling and compliance planning than ever before.
