How Permanent is "Permanent"?

When Congress labels a tax provision as “permanent,” it often only means “for now”—because many also come with built‑in expiration dates, or can be undone by future legislative action. That reality couldn't be more evident than in the sweeping One Big Beautiful Bill (OBBB), signed into law on July 4, 2025.

Permanent simply means that it is not scheduled to change.

Of course, that doesn't mean that it won't ever change due to a new administration!

The Sunset Paradox

Sunset provisions—scheduled expiration dates—give lawmakers flexibility in balancing budgets. But they also create planning uncertainty. And the OBBB is full of them.

Key Provisions of the OBBB & Their Length

Provision	Sunset or Effective Timing
Extension of 2017 individual tax rates	Made permanent
SALT deduction cap raised to $40,000	Reverts to $10,000 after five years (~2030)

Trump Accounts (for newborns)	Expires in 2028
Child tax credit increase ($200 boost)	Permanent

Green energy credits (IRA-era)	Wind/solar mid‑2026/late‑2027; EV credits end 2025; hydrogen 2027
Bonus depreciation & R&D expensing	Temporary: 2025–2029
Employer-provided student loan interest exemption	Permanent beginning Jan 1, 2026
Estate/gift tax exemptions ($15M individual / $30M couple)	Permanent, indexed for inflation after Dec 31, 2025
Charitable deduction floor (0.5% of AGI)	Appears permanent
Cap on itemized deduction benefit (35% of value)	Appears permanent after Dec 31, 2025

Planning in a Climate of Change

These varied timelines underscore how even dramatic tax reforms rarely guarantee permanence:

• Permanent provisions, like lower rates and higher estate exemptions, offer enduring benefits—but remain vulnerable to future repeal.

• Time-bound provisions, such as tip/overtime tax breaks and green energy credits, introduce fiscal cliffs that could shift financial outcomes drastically when they expire.

• Strategic sunsets may delay costs and make budgets balance temporarily—but set the stage for future political fights.

Bottom Line

“Permanent” often means “until further notice.” While some OBBB tax provisions are built to last, others are intentionally short‑lived—or dependent on future legislative decisions.

For taxpayers, the message is clear:

• Act now when favorable provisions are available.

• Plan for uncertainty, especially around expiring tax breaks.

• Monitor policy updates, particularly as key sunset dates approach (like 2028).

• Build flexibility into your financial and estate planning strategies.

  
  

In the world of tax policy, permanence is more political promise than financial guarantee.
