Understanding the Recent IRS Proposed Regulation Changes to the Corporate Alternative Minimum Tax
The Corporate Alternative Minimum Tax (CAMT) was introduced through the Inflation Reduction Act (IRA) as a way to impose a 15% minimum tax on the adjusted financial statement income (AFSI) of large corporations. This tax targets companies with an average annual income exceeding $1 billion over a three-year span, ensuring they contribute a more equitable share to federal taxes. Since taking effect for tax years beginning after December 31, 2022, the IRS has rolled out a series of notices and regulations to clarify how corporations must comply with CAMT.
Central to the CAMT is the determination of AFSI, which serves as the foundation for calculating the tax. Recently, the IRS issued proposed regulations that expand on earlier notices (such as Notices 2023-07, 2023-20, 2023-64, and 2024-10) to offer clearer definitions and guidance. These proposed rules lay out the statutory adjustments needed to determine whether a corporation falls under the CAMT’s scope. The tax only applies if a corporation’s tentative minimum tax, calculated at 15% of AFSI minus foreign tax credits, exceeds the regular corporate tax liability under the 21% corporate tax rate, plus any base erosion and anti-abuse tax (BEAT).
Specific provisions have been made for corporations that are part of foreign-parented multinational groups (FPMGs). For these entities, the AFSI calculation is modified, and the CAMT thresholds are lowered. Instead of the $1 billion income threshold, the threshold for FPMG companies is reduced to $500 million in average annual AFSI. Similarly, U.S. subsidiaries of foreign parent groups see their threshold lowered from $100 million to $50 million. The proposed regulations also address how affiliated corporations, particularly those filing consolidated tax returns, should navigate the CAMT. Rules around foreign tax credits, controlling interests, and net operating losses aim to provide further clarity on how CAMT obligations are calculated for complex corporate structures.
Recognizing the challenges that come with these new requirements, the IRS is offering measures to simplify compliance. One notable measure is the waiver of penalties for corporations that fail to pay estimated CAMT-related taxes for tax years starting after December 31, 2023, but before January 1, 2025. This relief is intended to give businesses additional time to adapt their financial reporting and compliance systems to the new tax structure. For certain corporations with smaller average AFSI, the proposed regulations introduce a simplified approach to determining CAMT liability, which helps ease the compliance burden for smaller entities within larger corporate groups, especially those affiliated with foreign corporations.
To meet CAMT’s requirements, affected corporations will need to update their accounting practices, as AFSI is distinct from both regular tax and financial accounting income. Detailed records will be essential in demonstrating compliance and calculating CAMT applicability each year. The regulations also stipulate that certain portions of the proposed rules will retroactively apply to 2024 transactions, even though the regulations aren’t finalized yet. Although most corporations won’t need to amend their 2023 tax returns, they should stay vigilant, as future and ongoing transactions could still be impacted.
The IRS is currently accepting public comments on these proposed regulations, with submissions due by mid-December 2024. A public hearing is scheduled for January 16, 2025, allowing stakeholders to provide feedback before the rules are finalized. As CAMT regulations continue to develop, corporations will need to stay informed and prepare for more stringent reporting and compliance requirements.
The CAMT introduces additional tax obligations for large corporations, particularly those with international operations or multi-entity structures. While the IRS is attempting to provide clarity and transitional flexibility, businesses impacted by this tax should start preparing now to ensure they meet the new requirements efficiently.
