If your business is still navigating the massive shifts brought by the “One Big Beautiful Bill” (OBBB), your most important meeting of the year starts at 2:00 p.m. ET today, March 24, 2026. The IRS is hosting a high-stakes IRS Business Tax Webinar (IR-2026-39) to provide the first official roadmap for the business provisions of this landmark legislation. In a rare move, the IRS has confirmed that recordings will not be posted, making this live session a “one-time-only” event for tax professionals and corporate leaders.
The session is set to dive deep into three critical pillars that will define the 2026 filing season:
- Permanent Corporate Rate Changes: Understanding the new baseline for your tax liability.
- Expanded R&D Credits: New opportunities for tech and manufacturing firms to reclaim investment costs.
- Revised Deduction Rules: Navigating the tightened (and in some cases, loosened) restrictions on business expenses.
For millions of corporations and pass-through entities, this IRS Business Tax Webinar is the definitive source to avoid costly errors on 2026 returns. The IRS experts will be addressing the specific nuances of the OBBB amendments, ensuring that “applicable entities” are fully compliant before the April deadlines loom. Registration is open until the very last minute, but with thousands of professionals expected to log in, securing your virtual seat now is a tactical necessity for any fiscal-minded organization.
