Purpose of the Legislation

The S Corporation Modernization Act of 2025 aims to update rules for S corporations—special business entities that pass income, losses, deductions, and credits directly to shareholders for federal tax purposes, avoiding double taxation at the corporate level. It seeks to make S corporations more flexible and attractive by relaxing ownership restrictions, simplifying income rules, and addressing tax issues related to shareholder deaths and deferred compensation.

Key Provisions

• Built-in Gains on Shareholder Death (Section 2): Introduces a new deduction for heirs of deceased S corporation shareholders. It allows amortization (spreading out) of certain "built-in gains" (unrealized appreciation in assets at death) over 15 years for depreciable property. Accelerated deductions apply if assets are sold. Gains later realized may be reclassified as ordinary income (taxed at higher rates than capital gains). Applies to deaths after enactment.
• Passive Investment Income Rules (Section 3): Raises the threshold for "passive income" (from sources like rents, royalties, interest, dividends, and annuities) from 25% to 60% of total gross receipts before triggering a corporate-level tax. Removes excessive passive income as a reason to revoke S corporation status. Expands exceptions for certain businesses (e.g., banks, lenders, finance companies). Applies to tax years starting after December 31, 2024.
• Nonresident Alien Shareholders (Section 4): Permits non-U.S. residents (nonresident aliens) to own S corporation stock, previously prohibited. Treats gains or losses from selling such stock as "effectively connected" to U.S. business (subject to U.S. tax) up to a calculated amount based on asset values. Requires S corporations to withhold tax on nonresident aliens' share of U.S.-connected income at the top individual tax rate (currently 37%). Adds a 10% withholding on stock sales by nonresidents. Applies to tax years starting after December 31, 2024, with sales rules from that date.
• Employee Shareholder Limit (Section 5): Treats all employees (and their estates) of an S corporation, plus certain wholly owned entities, as a single shareholder for the 100-shareholder limit. An "employee" includes workers under standard payroll definitions. Applies to tax years starting after December 31, 2024.
• IRAs as Shareholders (Section 6): Allows individual retirement accounts (IRAs), including Roth IRAs, to own S corporation stock directly. Exempts related stock sales within IRAs from "prohibited transaction" rules (which prevent self-dealing in retirement accounts). Effective January 1, 2026.
• Transfer of Suspended Losses on Death (Section 7): Permits heirs to inherit unused "suspended losses" (past deductions limited by a shareholder's basis or at-risk rules) from deceased owners, beyond just spousal transfers. Applies to deaths after enactment.
• Repeal of Deferred Compensation Rules (Section 8): Eliminates Section 409A, which taxed certain nonqualified deferred compensation plans (employer plans delaying pay without full pension protections) if not structured properly. Shifts some oversight to related rules under Section 457A. Applies to tax years starting after December 31, 2025.

Significant Changes to Existing Law

• Ownership Expansion: Previously, S corporations could not have nonresident aliens, most trusts (except specific types), or IRAs as shareholders, and the 100-shareholder cap counted each employee separately. These changes broaden eligibility.
• Income and Status Rules: The passive income cap increase and removal of termination for excess passive income reduce risks of losing S status. Built-in gains on death were previously taxed immediately to heirs; now they can be deducted over time.
• Tax Treatment: Introduces new withholding for foreign shareholders and recharacterizes some gains as ordinary income. Repeals Section 409A, simplifying deferred pay but potentially increasing immediate taxation under other rules.
• Loss and Basis Adjustments: Adds basis reductions for death-related deductions and allows loss transfers on death, which were more limited before.

Potential Impacts

• On Citizens and Businesses: Small and family-owned businesses (common S corporation users) gain flexibility to retain S status amid growth, attract employee ownership, and plan estates without large immediate tax hits. IRA owners can invest in S corporations for retirement growth. Deferred compensation repeal may simplify executive pay but could raise taxes if plans don't qualify under remaining rules.
• On Government Agencies: The IRS faces added administrative burdens, including new withholding enforcement, reporting for built-in gains, and regulations for foreign shareholders. This could increase compliance costs but reduce audits related to S status revocations.
• On International Relations: Allowing nonresident alien ownership may encourage foreign investment in U.S. businesses, boosting economic ties, but introduces U.S. tax obligations that could deter some investors due to withholding.

Main Stakeholders Affected

• S Corporation Owners and Shareholders: Benefit from easier status maintenance and estate planning.
• Heirs and Estates: Gain from deferred taxes on built-in gains and transferable losses.
• Nonresident Aliens: Newly eligible investors, but subject to U.S. withholding and taxes on connected income.
• Employees: Easier collective ownership without hitting shareholder limits.
• IRA Holders: Can now hold S corporation stock in retirement accounts.
• Businesses Using Deferred Compensation: Employers and executives see simplified rules but potential tax shifts.
• Financial Institutions (e.g., Banks): Benefit from passive income exceptions.

Notable Legal, Constitutional, or Political Implications

• Legal: Requires IRS to issue regulations for implementation (e.g., elections, withholding mechanics), potentially leading to litigation over gain calculations or foreign tax credits. Changes align with broader tax simplification efforts but may complicate international tax treaties.
• Constitutional: No direct challenges; amendments to the tax code fall under Congress's taxing power.
• Political: Positions as pro-small business reform, reducing barriers for domestic growth and foreign capital. Could face debate over revenue loss (estimated forgone taxes from deductions and thresholds) versus economic stimulus, with support from business lobbies and opposition from those concerned about IRS workload or foreign influence.
