The Trump Tax Cuts: TCJA, the Expiration Cliff and the "Big Beautiful Bill"
The 2017 Tax Cuts and Jobs Act slashed corporate rates permanently and cut individual rates through 2025. That deadline has arrived — font-size:1rem;max-width:640px;margin:0 0 8px;"> The 2017 Tax Cuts and Jobs Act slashed corporate rates permanently and cut individual rates through 2025. That deadline has arrived — here is what expires, what the "big beautiful bill" extends, and who pays and who benefits.
- The TCJA permanently cut the corporate tax rate from 35% to 21% — the individual cuts were set to expire after 2025, creating a fiscal cliff requiring congressional action
- Extending all expiring TCJA provisions costs approximately $4.6 trillion over 10 years (CBO); Trump's "big beautiful bill" adds further cuts (no tax on tips, no tax on overtime) for a $5-7T total
- The top benefits flow disproportionately to higher earners — the top 20% received roughly 65% of the TCJA's individual income tax benefits, according to Tax Policy Center analysis
- The SALT cap ($10,000 limit on state and local tax deductions) created an unusual intra-Republican conflict: members from high-tax states (NY, CA, NJ) want it raised, cutting into any revenue offset

The "Big Beautiful Bill" in 2026
The centerpiece of the 2025-26 Republican reconciliation package is permanently extending the expiring TCJA individual provisions. Without extension, taxes would rise automatically for most Americans — creating political pressure that Democrats argue GOP is exploiting by holding middle-class cuts hostage to cuts benefiting the wealthy.
The "big beautiful bill" adds new provisions Trump promised in 2024: no federal income tax on tips, no income tax on overtime pay, a senior deduction enhancement, and enhanced SALT deductions (contested within the GOP). The cost of these additions alone is estimated at $1-2T over 10 years.
Tax Policy Center analysis of TCJA extension finds that the top 20% of earners receive about 65% of the tax cut benefits. The bottom 60% receive less than 10% combined. The corporate rate cut — the most economically significant and permanent TCJA provision — primarily benefits shareholders and high-income investors.
