Congress quietly expands tax breaks for S corporation owners and executives

What it does

This bill modernizes S corporation tax rules by allowing stepped-up basis deductions for heirs when S corporation shareholders die, raising the passive income threshold from 25% to 60%, permitting nonresident aliens and IRAs to own S corporation stock, allowing employees to count as a single shareholder, and repealing Section 409A (nonqualified deferred compensation taxation). It also increases the shareholder limit from 100 to 250 and creates a withholding tax on nonresident alien shareholders' effectively connected income.

Why we flagged it

The bill's operative mechanism is a series of tax cuts and regulatory relaxations benefiting S corporation owners and executives. The title 'Modernization' masks what is functionally a narrowly targeted tax reduction for pass-through entities and their shareholders.

• Section 8 repeals Section 409A (nonqualified deferred compensation taxation), which is substantively unrelated to S corporation structural reform and primarily benefits executive compensation arrangements.

What the text implies

• The stepped-up basis deduction (Section 2) allows heirs to inherit S corporation stock with a basis reset to fair market value at death, eliminating capital gains tax on appreciation during the decedent's lifetime—a permanent wealth transfer benefit for high-net-worth families.
• Allowing nonresident aliens to own S corporation stock (Section 4) creates a withholding tax mechanism but may facilitate tax avoidance strategies by foreign investors; the 10% withholding on disposition gains may be insufficient to prevent erosion of the U.S. tax base.
