The "One Big Beautiful Bill": Key Tax Provisions You Should Know

Written by Gerry O'Connell, Enrolled Agent, Tax Planning Partner | Jul 8, 2025 4:52:40 PM

Top Tax Provisions from the 'One Big Beautiful Bill'

Welcome to our first take on the "One Big Beautiful" tax bill. As of going to print, details are still emerging, but, for now, we would like to present a high-level summary of what we know so far. We will be adding details to these and other relevant provisions in the coming weeks.
 
Highlights include the higher standard deductions for everyone (but especially those over 65), prevailing tax brackets made permanent going forward (no longer subject to increase in 2026), as well as the Lifetime Estate and Gift Tax exemption amount moving to $15M per taxpayer from 2026 (no longer subject to a 50% reduction).
 
The much-debated SALT limitation has been increased to $40,000 (from $10,000), but there is a fly in the ointment – the cap phases down to the original $10,000 when income surpasses $500,000 – though it is effective for 2025.
 
We will be updating all clients directly with a more detailed examination as we digest all 900 pages of the Bill.
