Section 899 Retaliatory Tax and ASC 740: What Finance Teams Must Know

Section 899 never became law. But for tax directors and CFOs at multinational enterprises, that fact alone does not close the file. The provision's near-enactment created real ASC 740 questions during Q1 and Q2 2025, its removal requires disclosure updates, and the OECD side-by-side package announced January 5, 2026 has opened a new layer of deferred tax complexity. This article answers the accounting questions that every policy and legal summary of Section 899 leaves on the table.

Key takeaway: Section 899 was never enacted under U.S. law and therefore never triggered the ASC 740 recognition threshold. Companies should not have recorded Section 899 rate increases in their income tax provisions. But disclosure of the legislative risk was appropriate while it was pending, and the post-enactment-failure cleanup is not trivial.

What Was Section 899 and Why Was It Dropped?

Section 899 was a proposed retaliatory tax provision in H.R. 1, the One Big Beautiful Bill Act, passed by the House on May 22, 2025. It would have imposed escalating additional U.S. federal income and withholding taxes on foreign individuals, corporations, sovereign wealth funds, and governments resident in countries that imposed "unfair foreign taxes" on U.S. businesses. Those unfair taxes were defined to include the OECD Pillar 2 Undertaxed Profits Rule (UTPR), digital services taxes (DSTs), and diverted profits taxes (DPTs).

The rate structure was severe. Under the House version, additional tax started at 5 percentage points above statutory rates, escalated by 5 points per year, and capped at 20 points above the statutory rate. The Senate Finance Committee markup, released June 17, 2025, moderated this to a 15-point cap and narrowed the trigger to extraterritorial taxes only, excluding standalone DSTs. The current 30% FDAP withholding rate on dividends, interest, rents, and royalties would have climbed to as high as 50% in combination with treaty rates under the House version, per the Congressional Research Service.

Section 899 also included a "Super BEAT" component that would have intensified the existing Base Erosion Anti-Abuse Tax (IRC Section 59A) for U.S. subsidiaries of foreign multinationals from targeted countries, removing the gross receipts and base erosion payment percentage safe harbors under the House version, or reducing the safe harbor from 3% to 0.5% under the SFC Markup.

The Joint Committee on Taxation scored Section 899 at $116 billion over ten years. The Tax Foundation estimated it would have raised taxes on investment from countries comprising roughly 80% of U.S. inbound foreign direct investment stock.

On June 27, 2025, Treasury Secretary Bessent requested the provision's removal following a G-7 agreement on international tax. The bill was enacted as P.L. 119-21 on July 4, 2025, without Section 899. For a broader overview of what the OBBBA did enact, see What Is the OBBBA? The 2026 Finance Professional's Guide.

Was Section 899 Ever "Enacted" for ASC 740 Purposes?

No. Section 899 never met the ASC 740 enactment threshold, and companies should not have recorded its rate increases in their income tax provisions.

Under ASC 740-10-25-47, the effect of a change in tax law is recognized in the period of enactment. For U.S. federal tax purposes, enactment occurs when the President signs the bill into law. House passage on May 22, 2025 did not constitute enactment. Senate Finance Committee markup did not constitute enactment. Neither event triggered any obligation to remeasure deferred tax assets or liabilities at Section 899 rates, or to record current tax expense at the elevated rates.

This is a distinction many practitioners got wrong during Q1 and Q2 2025. The correct treatment:

• Do not include Section 899 rate increases in the annual effective tax rate (AETR) calculation under ASC 740-270 for interim periods.
• Do not remeasure deferred tax balances at Section 899 rates.
• Do disclose the legislative risk as a material contingency in MD&A and income tax footnotes if the potential impact was material to the financial statements.

For companies with June 30, 2025 fiscal year-ends, the analysis is clean: Section 899 was dropped before the bill was signed on July 4, 2025, so it was never enacted at any point. For calendar-year companies filing Q2 2025 10-Qs, the appropriate disclosure was a note that Section 899 had been included in the House-passed bill, that it was pending Senate action, and that if enacted it could materially affect the company's U.S. tax obligations for specified categories of income.

Uncertain Tax Positions: Did Section 899 Require a FIN 48 Reserve?

For most companies, Section 899 did not require a new uncertain tax position (UTP) reserve under ASC 740-10 (the codification of FIN 48). But the treaty override dimension created a novel analysis that many tax teams had not previously modeled.

Section 899 would have overridden existing U.S. tax treaties. Under the House version, rate increases applied regardless of treaty reductions. Under the SFC Markup, treaty reductions survived but the additional tax continued to apply until it was 20 points higher than the non-treaty rate, for a combined maximum of 50%, per the CRS. Treaty override is rare in modern U.S. tax legislation, and it would have required companies to reassess all treaty-based withholding tax positions.

The UTP analysis turned on a threshold question: was there a tax position taken (e.g., applying a treaty-reduced withholding rate) that Section 899 would have rendered unsustainable? Because Section 899 was not enacted, no new UTP reserve was required. But companies that had already filed returns for periods that would have been affected needed to confirm that no accrual had been recorded in error.

A separate UTP question arose for U.S. entities making payments to sovereign wealth funds and foreign governments. Section 892 currently exempts foreign governments from U.S. withholding on passive investment income. Section 899 would have stripped that exemption for governments of targeted countries, per Gibson Dunn. That exposure was real enough during the pendency of the bill to warrant scenario analysis, even without a reserve.

Deferred Tax Modeling: The Escalating Rate Problem

The escalating rate structure of Section 899 created a deferred tax modeling problem with no clear precedent under ASC 740.

Deferred tax assets and liabilities are measured at the enacted tax rate expected to apply when the temporary difference reverses (ASC 740-10-30-8). Section 899's rate depended on how many years the foreign country's unfair tax remained in place: 5 points in year one, 10 in year two, 15 in year three, capped at 20 (House) or 15 (SFC). A company could not know which rate would apply at reversal without predicting foreign legislative behavior years in advance.

The practical answer, had Section 899 been enacted, would have been scenario analysis: model reversals at each possible rate, weight by probability, and disclose the range. The FASB has not issued specific guidance on escalating contingent tax rates. Companies would have been working from first principles under ASC 740-10-30.

Because Section 899 was not enacted, no deferred tax remeasurement was required. But any company that had begun preliminary modeling should confirm those estimates were not inadvertently carried into the provision.

The Super BEAT Interaction with Existing ASC 740 BEAT Positions

Companies with existing BEAT exposure under IRC Section 59A would have needed to re-model their entire BEAT ASC 740 position under Section 899's Super BEAT. The FASB staff's existing guidance on BEAT accounting adds a layer of complexity that no policy summary addressed.

The FASB staff has previously noted that companies must determine whether BEAT functions as an alternative minimum tax (in which case deferred taxes are measured at the regular rate with a valuation allowance for the AMT credit) or as a separate tax system. Section 899's Super BEAT would have compounded this analysis for foreign-parented groups from targeted countries by eliminating safe harbors and, under the House version, increasing the BEAT rate from 10% to 12.5%.

The SFC Markup took a different approach: it did not increase the BEAT rate for Section 899 purposes specifically, but it would have raised the BEAT rate for all taxpayers to 14% and lowered the base erosion percentage threshold to 2%. That change would have affected every company subject to BEAT, not just Section 899 targets, and would have required a full deferred tax remeasurement.

Since the SFC Markup's BEAT changes were also not enacted in P.L. 119-21, no remeasurement is required. But the BEAT rate and threshold changes in the enacted OBBBA are a separate matter, covered in GILTI Is Now NCTI: What to Disclose in Your Q2 2026 Form 10-Q.

Post-Enactment Failure: What to Do Now

Section 899 was dropped before enactment. Here is the practical checklist for finance teams:

1. Confirm no tax accrual was recorded. Because Section 899 was never enacted, any accrual recorded in anticipation of its passage was incorrect and must be reversed.
2. Update MD&A and footnote disclosures. 10-Qs filed during Q1 and Q2 2025 that disclosed Section 899 as a pending legislative risk should be followed by updated disclosure in subsequent filings confirming the provision was not enacted.
3. Reassess treaty-based withholding positions. No UTP reserve was required, but confirm that no reserve was recorded in error and that treaty-reduced withholding rates remain the correct position.
4. Review sovereign wealth fund and foreign government payment positions. The Section 892 exemption remains intact. Confirm that any temporary adjustments to withholding on payments to foreign governments have been reversed.
5. Document the analysis. Even though no accounting change was required, the ASC 740 file should document why Section 899 did not meet the enactment threshold and why no provision adjustment was made. Auditors will ask.
6. Build a monitoring framework. Section 899 has sustained Congressional support and a legislative history going back to 2023. The Treasury Secretary's removal request was driven by executive branch policy, not legislative failure, per the Treasury press release. A successor provision is politically feasible.

The OECD Side-by-Side Package and Your Pillar 2 Deferred Tax Analysis

The OECD's January 5, 2026 side-by-side package announcement does not, by itself, allow U.S. multinationals to remove Pillar 2 UTPR exposure from their ASC 740 analysis.

The OECD side-by-side package is designed to exempt U.S. multinationals from the UTPR and the Income Inclusion Rule (IIR) in respect of their foreign and domestic profits. This is directly relevant to ASC 740 because many U.S. multinationals had been modeling UTPR exposure in their deferred tax analyses. But the OECD announcement is not a binding legal change. It requires each Inclusive Framework country to amend its domestic legislation. Until those amendments are enacted jurisdiction by jurisdiction, U.S. multinationals cannot remove UTPR deferred tax exposure from their ASC 740 analysis based on the OECD announcement alone.

The practical implication: companies should monitor country-by-country legislative implementation and update their Pillar 2 deferred tax positions as each jurisdiction enacts the necessary changes. The OECD package may ultimately reduce exposure materially, but the timeline is uncertain. For a detailed treatment of the Pillar 2 ASC 740 mechanics, see OECD Pillar Two: What CFOs Must Do for ASC 740 in 2026.

The GAAP/IFRS Divergence

This is where U.S. GAAP reporters face a structural disadvantage relative to IFRS reporters. The IASB issued amendments to IAS 12 in May 2023 providing a temporary mandatory exception to recognizing and disclosing deferred tax assets and liabilities arising from Pillar 2 income taxes. FASB has not provided a parallel exception under ASC 740.

This means:

For multinational groups with both U.S. GAAP and IFRS reporters, this divergence requires separate analyses and separate disclosures. The OECD side-by-side package may narrow the gap over time as country-level legislative implementation reduces the underlying exposure, but it does not eliminate the GAAP/IFRS analytical difference.

SEC Disclosure Expectations During the Pendency of Section 899

The SEC has not issued specific staff guidance on Section 899 disclosure. But the existing framework under Regulation S-K Item 303 (MD&A) and ASC 450 (contingencies) was clear enough: a material pending tax legislation risk requires disclosure if the outcome is reasonably possible and the financial impact is estimable or at least describable.

For companies with significant FDAP withholding obligations to foreign persons in UTPR-adopting countries, or with U.S. subsidiaries of foreign parents from those countries, Section 899 was a material risk during Q1 and Q2 2025. Best-practice disclosure in 10-Qs filed during that period included:

• A description of Section 899 and its legislative status (House-passed, Senate pending).
• The categories of income and persons potentially affected.
• A qualitative statement that if enacted, the provision could materially increase the company's U.S. tax obligations or the tax cost of inbound investment.
• A note that the provision had not been enacted and therefore had not been reflected in the income tax provision.

Companies that included this disclosure in Q1 or Q2 2025 filings should update subsequent filings to confirm the provision was not enacted in P.L. 119-21.

Legislative Risk: Could Section 899 Come Back?

Yes, and finance teams should treat it as a live risk rather than a closed chapter. Section 899 drew on legislation proposed by House Ways and Means Chairman Jason Smith in 2023 and early 2025, and incorporated BEAT-related provisions from Rep. Ron Estes (H.R. 2423), per Gibson Dunn. Congressional Republicans stated they "stand ready to take immediate action" if the G-7 side-by-side deal is not implemented, per the European Tax Blog's analysis of the G-7 statement.

The OECD Inclusive Framework must now translate the G-7 understanding into binding country-level rules across more than 145 jurisdictions. That process is slow and faces resistance from countries not party to the G-7 agreement, including India and China. If the side-by-side package stalls, Section 899 or a successor provision is the most likely Congressional response.

A monitoring framework for your ASC 740 process should include:

• Quarterly review of OECD Inclusive Framework progress on the side-by-side package.
• Tracking of Treasury Secretary designations of additional "unfair foreign taxes" (Section 899 granted broad discretionary authority that could be revived in successor legislation).
• Scenario modeling of Section 899-type exposure for the four most-affected categories: sovereign wealth funds, PE funds, U.S. borrowers with tax gross-up provisions, and U.S. subsidiaries of foreign multinationals.
• A pre-built disclosure template that can be activated quickly if successor legislation advances.

The ASC 740 valuation allowance audit red flags framework is also relevant here: legislative uncertainty of this kind can affect the realizability of deferred tax assets and should be factored into the positive and negative evidence assessment.

FAQ

Did Section 899 pass into law? No. The House passed H.R. 1 including Section 899 on May 22, 2025. The Senate did not include it. The One Big Beautiful Bill Act was signed into law as P.L. 119-21 on July 4, 2025, without Section 899.

Should we have recorded a tax provision for Section 899 rates in Q1 or Q2 2025? No. Under ASC 740-10-25-47, tax law changes are recognized only upon enactment (Presidential signature). House passage does not constitute enactment. No rate remeasurement or current tax accrual was appropriate.

What disclosures were appropriate while Section 899 was pending? For companies with material exposure, disclosure of the legislative risk in MD&A and the income tax footnote was appropriate under Regulation S-K Item 303 and ASC 450. The disclosure should have described the provision, its status, the categories of income affected, and the fact that it had not been reflected in the provision because it was not enacted.

Does the OECD side-by-side package remove our Pillar 2 UTPR deferred tax exposure? Not immediately. The January 5, 2026 OECD announcement requires country-by-country legislative implementation. Until each relevant jurisdiction enacts the necessary changes, UTPR exposure cannot be removed from the ASC 740 analysis based on the OECD announcement alone.

How does the FASB treat Pillar 2 deferred taxes differently from the IASB? The IASB issued a temporary mandatory exception to IAS 12 for Pillar 2 deferred taxes in May 2023. FASB has not provided a parallel exception under ASC 740. U.S. GAAP reporters must apply the full ASC 740 framework to Pillar 2 deferred tax impacts.

Could Section 899 return in future legislation? Yes. The provision has sustained Congressional support since 2023, and Republicans have signaled willingness to act if the G-7 side-by-side deal stalls. Companies should maintain a monitoring framework and pre-built disclosure templates rather than treating the issue as resolved.
