S Corporations in 2025 and Beyond: How to Maximize Tax Benefits Under Subchapter S  

The One Big Beautiful Bill Act (OBBB), signed July 4, 2025, introduces major updates for S corporations by locking in and expanding provisions from the 2017 Tax Cuts and Jobs Act (TCJA).

OBBB makes permanent the lower individual tax rates, widens the tax brackets, and extends the Qualified Business Income (QBI) deduction under Section 199A beyond 2025. This allows S corporation shareholders to exclude up to 20% of qualified business income, cutting tax liability by 20% or more. Expanded phase-out thresholds starting in 2026 will widen access to this deduction.

This discussion will also cover how OBBB impacts entity choice decisions from staying an S corp to electing C corp status and qualifying for enhanced Qualified Small Business Stock (QSBS) treatment. We’ll break down the temporary SALT deduction cap increase to $40,000 (2025–2029), how it phases out for high earners, and how it compares to state-level pass-through entity tax (PTET) regimes.

THIS WEBINAR IS NOT ELIGIBLE FOR CTEC CREDIT.

Who should attend:  Tax professionals, advisors, and business owners who work with or operate S corporations and need to assess how OBBB changes affect entity choice, planning, and shareholder tax outcomes.
