Tariffs
In Q2 2026, the Customs and Border Protection’s (CBP) Consolidated Administration and Processing of Entries (CAPE) system began processing and paying refunds on certain International Emergency Economic Powers Act (IEEPA) tariff claims. Companies should continue to evaluate whether they meet the criteria to record a refund receivable for IEEPA tariffs paid either under the gain contingency model (ASC 450-30) or under the loss recovery model (ASC 410-30). Based on that assessment, companies will need to determine whether any tariff refunds should be included in the estimated annual effective tax rate or as a discrete item (i.e., a significant infrequent or unusual item) in the interim provision, if applicable.

Updates from the Financial Accounting Standards Board (FASB) and Securities and Exchange Commission (SEC)
The FASB issued two new accounting standards updates (ASUs) during the second quarter of the year, including the following:
- ASU 2026-01 – Equity (Topic 505): Initial Measurement of Paid-in-Kind Dividends on Equity-Classified Preferred Stock
- ASU 2026-02 - Environmental Credits and Environmental Credit Obligations (Topic 818)
While these ASUs may not have a direct impact on a company's tax provision, it is crucial for tax professionals to monitor these updates as these ASUs may impact pretax income when they become effective.
On May 5, 2026, the SEC issued a proposal to allow public companies to elect semi-annual reporting rather than the current quarterly reporting requirements. Shortly thereafter, on May 19, 2026, the SEC issued two other proposals which would, among other things, expand the availability of Form S-3, expand the ability to incorporate information by reference in Form S-1, and increase the public float threshold while adjusting certain other requirements that must be met for a company to be classified as a ‘large accelerated filer.’ These proposed changes could provide for significant relief of reporting burdens for certain public companies.
Read about the various provisions of these proposals and their potential impacts in our financial reporting insights: SEC proposal could reshape interim reporting for public companies, SEC proposal could expand access to registered capital markets and SEC proposal could provide reporting relief for many public companies.
State tax
A growing number of states addressed the OBBBA during the second quarter of 2026. The uneven state conformity will continue to put pressure on corporate taxpayers with increasingly complex state income tax calculations through conformity and/or decoupling positions on various provisions. Companies should continue to monitor these updates closely and reflect the changes in the financial statements in the period of enactment. More discussion on this topic can be found in our tax alert: State corporate income tax law changes for the second 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
In January 2026, the OECD released its side-by-side (SbS) package, which introduced the SbS and ultimate parent entity (UPE) safe harbors intended to provide relief from Pillar Two exposure under the income inclusion rule (IIR) and undertaxed profits rule (UTPR) for eligible U.S.-parented multinational groups beginning in fiscal years starting on or after Jan. 1, 2026. The package also includes several administrative and compliance simplification measures, including a permanent simplified effective tax rate safe harbor, an extension of transitional country-by-country reporting (CbCR) safe harbor relief and a substance-based tax incentive safe harbor. Notably, the package does not apply to qualified domestic minimum top-up taxes (QDMTTs), and in-scope multinational enterprise (MNE) groups must continue to satisfy annual GloBE Information Return (GIR) filing requirements.
The financial reporting impact of these measures remains dependent on enactment by individual jurisdictions. As of June 30, 2026, most jurisdictions have not enacted legislation implementing the SbS package. Notably, Canada introduced Bill C-31 on May 6, 2026, which, if enacted, would implement the SbS and UPE safe harbors, extend transitional CbCR safe harbor relief by one year and defer the effective date of Canada's UTPR by one year.
The absence of enacted legislation in many jurisdictions may limit the ability of U.S.-parented groups to conclude that SbS relief is available when evaluating Pillar Two exposures under ASC 740. Accordingly, companies should continue to assess potential IIR and UTPR exposures based on legislation enacted as of the reporting date and monitor legislative developments on a jurisdiction-by-jurisdiction basis. Consistent with ASC 740, legislative impacts must be recognized in the period of enactment.
OECD guidance on centralized GIR filing
Thirty-seven jurisdictions have implemented a qualified IIR and/or QDMTT that applies to in-scope groups beginning with their 2024 fiscal year. Under the GloBE Model Rules and Commentary, these jurisdictions require an MNE group to satisfy GIR filing obligations in each jurisdiction where it is subject to the rules. However, Pillar Two includes a centralized filing mechanism that allows an MNE group to file a single GIR in one jurisdiction and have that information exchanged with other relevant jurisdictions. Recognizing that many jurisdictions may not have operational filing portals or information exchange arrangements in place before the first GIR filing deadline, participating 2024 Implementing Jurisdictions agreed to a one-time administrative measure intended to facilitate compliance during the initial reporting cycle, subject to certain jurisdiction-specific reservations and limitations.
On May 18, 2026, the OECD published a ‘Common Understanding’ among participating jurisdictions establishing a transitional framework for the first GIR filing year. Under this framework, an MNE group may file its 2024 GIR in a qualifying filing jurisdiction. Where an MNE group timely files its GIR in one of these qualifying jurisdictions and complies with all applicable local notification requirements, participating jurisdictions generally agreed to use mechanisms available under their domestic law to waive penalties that might otherwise apply or not enforce their local GIR filing obligation before the relevant GIR exchange deadline. In effect, the centrally filed GIR, together with any required local notifications, will generally satisfy the group's local GIR filing obligations in participating jurisdictions for the first reporting year.
However, this relief is temporary and subject to several conditions. It does not permanently replace local filing requirements. Under the GIR Multilateral Competent Authority Agreement (MCAA), the filing jurisdiction is expected to exchange the relevant GloBE information with other implementing jurisdictions by Dec. 31, 2026, for calendar-year groups filing by June 30, 2026. If a jurisdiction does not receive the GIR through the exchange mechanism by that date, it may require the MNE group to file the return locally in accordance with its domestic law. In addition, the OECD's Common Understanding makes clear that any relief from local filing requirements or penalties applies only to the extent permitted under local law. As a result, the availability of transitional relief ultimately depends on each jurisdiction's domestic legislative and administrative framework.
