Corporate alternative minimum tax (CAMT): Notice 2026-7
Notice 2026-7, released Feb. 18, 2026, adds additional taxpayer-friendly adjustments to the CAMT calculation. The notice added several new adjustments to the calculation of adjusted financial statement income (AFSI) that more closely align the calculation with federal taxable income, which are expected to impact a wide range of corporate entities. These changes include the following adjustments when calculating AFSI:
- Amortization on domestic research and development costs capitalized under section 174 from 2022 through 2024.
- Amortization of goodwill and ‘eligible’ section 197 intangible assets. An ‘eligible’ intangible is an intangible that is not amortized for book purposes but rather would be expensed upon impairment or disposal.
- Certain repairs, maintenance, materials and supply costs, where these costs are capitalized for book purposes.
These adjustments were introduced by the Treasury largely in response to requests from entities that were more likely to pay CAMT in the future due to the changes to federal taxable income after the enactment of the OBBBA. In addition to the new AFSI adjustments, the notice provided clarity and guidance around the treatment of fresh start accounting adjustments and attribute reduction for companies emerging from bankruptcy and around the treatment of transfers of intangible property or stock to or from a foreign corporation for purposes of CAMT.
Under ASC 740, entities subject to CAMT should continue to measure their deferred taxes using the regular federal statutory tax rate of 21%; however, they may consider the effect of CAMT in assessing the need for a valuation allowance. Given the evolving nature of CAMT guidance, entities should continue to evaluate the impacts on any unrecognized tax benefits and the assessment of the need for a valuation allowance, if applicable.
Tariffs
On Feb. 20, 2026, the Supreme Court ruled that the tariffs put in place as part of the International Emergency Economic Powers Act (IEEPA) were unlawful, and on March 5, 2026, the US Court of International Trade issued an order that could result in refunds of tariffs previously paid by importers. The impacts of this decision are wide-ranging, complex and uncertain. To read more about the potential impacts and uncertainties, read our Accounting Brief: Update on Potential Tariff Refunds.
Updates from Financial Accounting Standards Board (FASB)
The FASB did not issue any new accounting standards updates (ASUs) during the first quarter of 2026, but that does not mean that there is no work to be done. Some of the ASUs issued in 2025 and recent years are effective for years beginning after Dec. 15, 2025, generally calendar year 2026, including the following:
- ASU 2025-05 – Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets
- ASU 2024-04 – Debt – Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments
Additionally, many of the other ASUs issued in 2025 allow for early adoption.
It is not often that these updates are directly related to ASC 740, but it is crucial for tax professionals to stay attuned to these updates as changes to pre-tax income may affect the income tax provision.
In December of 2025, the FASB finalized ASU 2025-10, Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities. Read more about the ASU and the impact on entities in RSM US’ Financial Reporting Insights: FASB issues guidance on accounting for government grants.
State tax
A significant number of states have adopted legislation in Q1 2026 in response to the OBBBA. The results vary widely from state to state, potentially adding complexity to state tax calculations for the foreseeable future. Companies should monitor these changes closely throughout the year, and updates on state law changes for Q1 are discussed in State corporate income tax law changes for the first quarter of 2026.
Global tax compliance updates: OECD Pillar Two and country-specific changes
The following section includes key global tax law updates contributed by RSM’s global teams.
Status of Pillar Two
The OECD’s January 2026 ‘side-by-side’ (SbS) package introduces a coordinated framework that allows U.S.-parented multinational enterprises to coexist with Pillar Two global minimum tax rules while significantly reducing exposure to top-up taxes. Effective for fiscal years beginning on or after Jan. 1, 2026, the package provides elective safe harbors, most notably the SbS and ultimate parent entity (UPE) safe harbors, that can effectively eliminate liability under the income inclusion rule (IIR) and undertaxed profits rule (UTPR) for eligible U.S. groups. Additional measures, including a permanent simplified effective tax rate safe harbor, an extension of transitional country-by-country (CbC) reporting relief, and a substance-based tax incentive safe harbor, are intended to streamline compliance and preserve the intended 15% minimum tax framework while recognizing the U.S. tax system as broadly aligned with Pillar Two objectives.
While the package represents a significant policy shift, its financial reporting impact will depend on jurisdictional enactment. U.S. multinationals may still face interim volatility where top-up taxes must be accrued prior to local enactment of the SbS rules, even if ultimately relieved upon enactment. Importantly, the relief does not extend to qualified domestic minimum top-up taxes (QDMTTs), and companies must continue to meet global anti-base erosion (GloBE) reporting requirements and invest in data, governance and modeling capabilities. As such, the package reduces global minimum tax exposure but does not eliminate compliance complexity, requiring continued monitoring of legislative developments and proactive planning around elections, incentives, and reporting positions. Visit OECD's ‘side-by-side’ package offers a path for US multinational enterprises for detailed discussions.
As of March 2026, most jurisdictions have not enacted legislation implementing the SbS Package. While the European Union (EU) has formally acknowledged the SbS package as a qualifying safe harbor framework under the EU Minimum Tax Directive, application of the SbS provisions generally requires national level legislative or administrative implementation by individual member states. The United Kingdom announced on Jan. 7, 2026, its intention to implement the SbS package with effect for accounting periods beginning on or after Jan. 1, 2026; however, legislation is expected to be introduced in the next Finance Bill which is likely to be enacted in the Spring of 2027.
