NCTI Deferred Tax Restatement Under ASC 740: A Practitioner Walkthrough

If your company has CFC structures and you filed a Q3 2025 10-Q, there is a real question on the table: did you correctly remeasure your GILTI deferred taxes under the new NCTI rules? Get it wrong and you are not looking at a quiet Q4 correction. You may be looking at a restatement.

This walkthrough covers the six-step ASC 740 remeasurement process for NCTI, the two policy choices you must document, the restatement trigger analysis under ASC 250, and what your 2025 annual and 2026 interim disclosures need to say.

Key takeaway: The One Big Beautiful Bill Act (OBBBA, PL 119-21), signed July 4, 2025, renamed GILTI to Net CFC Tested Income (NCTI) and made structural changes that required deferred tax remeasurement in Q3 2025, not when the new rules become effective in 2026. Companies that missed or underestimated that obligation face restatement exposure.

What Changed from GILTI to NCTI Under the OBBBA

The GILTI-to-NCTI rename is not cosmetic. The underlying economics changed materially for tax years beginning after December 31, 2025, and the ASC 740 remeasurement obligation landed in Q3 2025, the period of enactment.

The three structural changes that directly affect deferred tax measurement are:

Removing QBAI increases the NCTI inclusion base for most multinationals with tangible-asset-heavy CFC structures. The Section 250 deduction reduction to 40% raises the effective U.S. tax rate on NCTI inclusions. The FTC haircut dropping from 20% to 10% partially offsets that, but the net effect on deferred tax liabilities and assets depends on your specific CFC profile.

As Deloitte DART puts it: "While many of these changes are not effective until a future taxable year, deferred tax assets and liabilities that are expected to reverse after the new tax provisions are effective should be remeasured in the period of enactment."

For calendar-year companies, that period is Q3 2025. The OBBBA also permanently extends the CFC look-through rule under IRC Section 954(c)(6), which may require you to reassess whether the ASC 740-30-25-18(a) indefinite reversal exception still applies to outside basis differences in your CFCs.

For the FDDEI side (formerly FDII), the deduction drops from 37.5% to 33.34% under the OBBBA. That is a separate deferred tax modeling question, covered in our FDII to FDDEI practitioner guide.

The Six-Step NCTI Deferred Tax Remeasurement Process

Work through these steps in sequence. Each one gates the next.

Step 1: Determine Whether You Elected the GILTI Deferred Policy

If your company previously elected to record deferred taxes on GILTI, you must remeasure those deferred tax assets and liabilities using the new NCTI rules. This is not optional under ASC 740-10-25: the effect of a change in tax law must be recognized in income from continuing operations in the period that includes the enactment date.

If you did not elect the GILTI deferred policy, go to Step 2 before assuming you can skip the rest.

Step 2: Reassess the Policy Election If You Did Not Record GILTI Deferreds

Companies that treated GILTI as a period cost (no deferred taxes) need to ask whether that policy remains defensible given the structural changes. The QBAI elimination, new deduction rates, and FTC haircut reduction change the economics of NCTI inclusions materially. If your NCTI profile has shifted significantly, the prior policy rationale may no longer hold.

A policy change from period-cost to deferred-tax treatment is a change in accounting principle under ASC 250, requiring retrospective application and robust disclosure. Get your auditors aligned before you move.

Step 3: Model the QBAI Elimination Impact on Your Deferred Tax Rollforward

For companies on the GILTI deferred policy, the QBAI elimination is the most mechanically complex change. Previously, GILTI was reduced by 10% of the CFC's qualified business asset investment (net tangible assets). Removing that subtraction increases the NCTI inclusion base.

Practically, this means:

• Pull your CFC-level QBAI calculations from the prior GILTI workpapers.
• Recompute the projected NCTI inclusion for years in which your existing deferred tax assets and liabilities are expected to reverse, using the post-QBAI base.
• Update the deferred tax rollforward to reflect the higher inclusion amount.

Note that the OBBBA also reinstated 100% bonus depreciation for qualified property placed in service after January 19, 2025. While QBAI is now eliminated, bonus depreciation still affects book-tax temporary differences and deferred tax liabilities on domestic assets, and those interact with your overall taxable income projections used in the valuation allowance assessment.

Step 4: Apply the New Section 250 Deduction Rate and FTC Haircut

Deferred tax assets and liabilities that are expected to reverse in tax years beginning after December 31, 2025 must be remeasured at the new effective rate, which incorporates:

• The 40% Section 250 deduction (reducing the taxable NCTI inclusion)
• The 10% FTC haircut (instead of 20%)

The combined effect on your effective NCTI tax rate is company-specific. Run the computation at the CFC level, not as a blended estimate. Baker Tilly notes that "companies that model the reversal of deferred income taxes to determine the realizability of deferred tax assets could have material impacts on the Q3 provision, specifically the period of enactment."

For deferred tax assets and liabilities reversing before December 31, 2025, use the prior GILTI rates. The effective date stagger matters: not all reversals are subject to the new rules simultaneously.

Step 5: Reassess the Valuation Allowance, Including the Two NCTI Policy Views

This is where the analysis gets most consequential, and where the two acceptable policy views diverge.

The two views on NCTI as a source of future taxable income:

Deloitte's Roadmap Income Taxes (Section 5.7.2) identifies two acceptable positions for how future NCTI inclusions factor into the valuation allowance realizability assessment:

• View A: Future NCTI inclusions are a source of future taxable income and can support realization of deferred tax assets, similar to how projected future taxable income is used.
• View B: Future NCTI inclusions are not a reliable source of future taxable income for valuation allowance purposes, because NCTI is itself an inclusion driven by CFC-level results that are uncertain.

As Deloitte DART states: "Regardless of an entity's policy choice, the collective changes to GILTI may affect the amount of valuation allowance required."

The policy choice between these views can produce materially different valuation allowance amounts. You must:

1. Determine which view you have been applying (or document a new policy choice).
2. Apply it consistently across all deferred tax asset realizability assessments.
3. Document the policy in your tax provision workpapers with enough specificity to survive auditor scrutiny.

If you are switching views, that is a change in accounting principle. If you are applying a view for the first time because you previously had no GILTI deferreds, document it as a new policy election.

The NCTI remeasurement also interacts with CAMT credit carryforward valuation allowances. In certain circumstances, OBBBA changes may increase current-period taxes payable and the CAMT tax credit carryforward, compounding the valuation allowance reassessment challenge. See our CAMT Notice 2026-7 analysis for the AFSI interaction.

For the Section 163(j) interest limitation side, the OBBBA permanently reinstates the EBITDA-based ATI calculation, generally increasing deductible interest expense. This affects valuation allowance assessments for interest carryforward deferred tax assets and interacts with NCTI taxable income projections. Our Section 163(j) guide covers that mechanics separately.

Step 6: Prepare the Disclosures

The NCTI remeasurement triggers disclosure obligations under multiple ASC 740 subsections. See the full disclosure requirements in the section below.

Did Q3 2025 Get It Wrong? Restatement Risk Under ASC 250

This is the question the top-ranking guidance does not answer directly. Here is the framework.

Under ASC 740-10-25, the effect of new tax legislation must be recognized in the period of enactment. For calendar-year companies, that is Q3 2025. If a company failed to remeasure NCTI deferred taxes in Q3 2025, the question is whether that failure is:

• An error under ASC 250-10-20 (incorrect application of GAAP), requiring restatement if material, or
• A change in estimate correctable in Q4 or the annual filing without restatement.

The answer turns on the nature of the failure:

A missed remeasurement obligation is not a change in estimate. It is a failure to apply the bright-line ASC 740-10-25 rule. If the amount is material to Q3 2025 financial statements, restatement under ASC 250 is required. The materiality analysis should consider both the quantitative impact on the income tax provision and the qualitative factors, including whether the error affects a metric that investors or analysts focus on.

If you are now reviewing Q3 2025 and finding gaps, engage your external auditors before the annual filing. A pre-filing review of NCTI deferred tax positions is far less costly than a post-filing restatement. The SOX 302 certification process also requires your CFO and principal accounting officer to evaluate whether Q3 disclosures were accurate. Our SOX 302 walkthrough covers the certification obligations in detail.

Key takeaway: A failure to remeasure NCTI deferred taxes in Q3 2025 is an error under ASC 250, not a change in estimate. If material, it requires restatement. The audit committee should be briefed before the annual filing is issued.

ASC 740 Disclosure Requirements for NCTI Remeasurement

For the 2025 annual 10-K and 2026 interim 10-Qs, the following disclosures apply:

ASC 740-10-50-9 requires disclosure of the significant components of income tax expense or benefit for each year presented. If the NCTI remeasurement is material, it must be disclosed as a significant component, broken out from the routine deferred tax provision.

ASC 740-10-50-14 requires disclosure of the nature and effect of any significant matters affecting comparability of information for all periods presented, if not otherwise evident. The NCTI remeasurement and any policy changes triggered by OBBBA meet this threshold for most multinationals.

ASU 2023-09 adds a new layer. Effective for public business entities for fiscal years beginning after December 15, 2024 (calendar-year 2025 annual filings), ASU 2023-09 requires disaggregated rate reconciliation and income taxes paid disclosures. The NCTI-related deferred tax adjustments will need to be reflected in the disaggregated rate reconciliation, separately identified from other international tax items. Our ASU 2023-09 vs IAS 12 comparison covers the new disaggregation mechanics in detail.

Footnote labeling: Update deferred tax footnote descriptions from "GILTI" to "NCTI" for periods after enactment. The SEC staff will expect the terminology to reflect the enacted law. A parenthetical noting the rename ("Net CFC Tested Income, formerly GILTI") is good practice in the first filing cycle.

Outside basis differences: If the CFC look-through rule extension under IRC Section 954(c)(6) affects your ASC 740-30-25-18(a) indefinite reversal exception analysis, disclose the change in position and any previously unrecognized deferred taxes now required to be recorded.

NCTI Remeasurement Checklist for Tax Teams

Use this before signing off on any 2025 annual or 2026 interim filing:

1. Confirm policy election status. Did the company elect the GILTI deferred policy? Document the answer in the provision workpapers.
2. If no GILTI deferreds were recorded, assess whether the NCTI structural changes require a policy reassessment. Document the conclusion.
3. Pull CFC-level QBAI data from prior GILTI workpapers and recompute projected NCTI inclusion without the QBAI subtraction for reversing deferred tax periods.
4. Apply the new Section 250 deduction rate (40%) and FTC haircut (10%) to deferred tax assets and liabilities reversing in tax years beginning after December 31, 2025.
5. Document your policy choice on the two acceptable views for NCTI as a source of future taxable income (Deloitte Roadmap Section 5.7.2). Apply it consistently.
6. Reassess the valuation allowance using the documented policy view. Separately assess CAMT credit carryforward realizability.
7. Review Q3 2025 for errors. If the remeasurement was not done or was materially incorrect, perform a materiality analysis and brief the audit committee.
8. Prepare ASC 740-10-50-9 and ASC 740-10-50-14 disclosures for the NCTI remeasurement, including the ASU 2023-09 disaggregated rate reconciliation.
9. Update footnote terminology from GILTI to NCTI.
10. Reassess the ASC 740-30-25-18(a) exception for outside basis differences in light of the permanent CFC look-through rule extension.

FAQ

When exactly did the NCTI remeasurement obligation arise? The OBBBA was signed July 4, 2025, making that the enactment date for ASC 740 purposes. Calendar-year companies were required to reflect the remeasurement in Q3 2025 (period ended September 30, 2025). The new NCTI provisions are effective for tax years beginning after December 31, 2025, but deferred taxes reversing after that date must be remeasured at the new rates in the period of enactment, not when the provisions take effect.

We have a June 30 fiscal year. When was our enactment period? Your enactment period is the fiscal quarter that includes July 4, 2025. For a June 30 fiscal year, that is Q1 of fiscal year 2026 (the quarter ended September 30, 2025). The same remeasurement obligations apply; the timing of your 10-Q filing differs from calendar-year companies.

Do we need to change our accounting policy from GILTI deferred to period-cost, or vice versa? No automatic policy change is required. Companies on the GILTI deferred policy remeasure using the new NCTI rules but stay on the deferred policy. Companies not on the deferred policy should assess whether the structural changes make a policy change appropriate, but there is no GAAP requirement to switch. A voluntary change is an accounting principle change under ASC 250.

What documentation will auditors expect for the two NCTI policy views? Auditors will expect a written policy memo that identifies which view the company applies (View A or View B on NCTI as a source of future taxable income), explains the rationale, and demonstrates consistent application across all deferred tax asset realizability assessments. The memo should reference Deloitte Roadmap Section 5.7.2 or equivalent authoritative guidance and be included in the tax provision workpaper package.

How does the NCTI remeasurement interact with our valuation allowance on R&E deferred tax assets? The OBBBA allows domestic R&E expenses to be deducted as incurred starting in 2025, reversing the TCJA's five-year amortization requirement. Unamortized balances from 2022 to 2024 can be fully deducted in 2025 or partially over 2025 and 2026. This may release R&E-related deferred tax assets, which interacts with the overall valuation allowance assessment alongside the NCTI remeasurement. Under Revenue Procedure 2025-28, small business taxpayers can amend 2022 to 2024 returns, but the Q3 2025 provision must reflect actual filing status, not intent. Our Section 174A deferred tax reversal guide covers the R&E mechanics in detail.

What if our NCTI remeasurement produces a counterintuitive result, such as a larger deferred tax asset after remeasurement? That can happen. The FTC haircut reduction from 20% to 10% lowers the net tax cost of NCTI inclusions, which may reduce deferred tax liabilities for companies with significant foreign tax credits. Simultaneously, the QBAI elimination increases the NCTI base, raising the gross inclusion. The net effect depends on your CFC-level foreign tax rates and asset profiles. Model each CFC separately before drawing a conclusion.
