To understand why planners describe the One Big Beautiful Bill Act as making their work easier, you have to remember the problem it solved, because it was not primarily about how much tax anyone paid.

For years, nearly every major provision of the 2017 Tax Cuts and Jobs Act was scheduled to expire on January 1, 2026. Most consequentially, the estate and gift tax exemption was set to be cut roughly in half. That created a deadline problem: families with large estates faced pressure to give away enormous sums before the sunset, permanently and irreversibly, to lock in an exemption that might vanish. Give too much and you impoverish yourself for a tax that might never have applied. Wait and you might lose millions in exemption. As one firm put it, the possible sunset complicated estate planning, and there was no way to know the right answer.

Signed July 4, 2025, OBBBA removed that deadline. That is the actual story of the past year.

What genuinely became permanent

The provisions that were made permanent are the ones that make planning meaningfully simpler, because permanence lets you build a strategy that does not need a contingency plan.

The estate and gift tax exemption is set at $15 million per person in 2026, $30 million for married couples, indexed to inflation from 2027, with no sunset, and with no more threat of clawback for prior gifts. Equally important is what did not change: the step-up in basis at death remains intact, top estate and gift rates stay at 40%, trust income tax brackets are unchanged, and grantor trusts, SLATs, and GRATs remain unaffected. The entire architecture of estate planning survived untouched, which is why the mood in that field is relief rather than upheaval.

The Section 199A qualified business income deduction, the 20% deduction for pass-through businesses, was made permanent, giving small-business owners genuine long-term clarity. The lower TCJA brackets and the doubled standard deduction, now $15,750 single and $31,500 joint, indexed for inflation, also became permanent.

There is a real change in kind here. Planning under a sunset means every decision carries an implicit bet on what Congress will do. Planning under permanence means you can optimize for the client's actual life, health, family, business, rather than for a legislative calendar. That is why practitioners describe the work as easier even where the dollar amounts did not move much.

The catch: "permanent" means "until Congress changes it"

One honest caveat before the good news gets oversold. The increase is permanent because no automatic sunset was added, meaning it will not decrease unless a future Congress and President enact legislation to change it.

That is a meaningfully different thing from immutable. It shifts the default: previously the exemption would halve automatically unless Congress acted, now it persists unless Congress acts. That reversal is genuinely valuable, inertia now works in taxpayers' favor. But a family building a multi-decade dynasty trust on the assumption that $15 million is fixed forever is making a political forecast, not reading a guarantee. Tax law has no permanence that a future Congress cannot undo.

The part the "easier" framing skips: a new set of cliffs

Here is what the celebratory coverage tends to bury. OBBBA did not eliminate deadline-driven planning. It replaced one enormous cliff with a staggered series of smaller ones, and several are close.

The SALT deduction cap rose from $10,000 to $40,000, indexed, but only for 2025 through 2029, reverting to $10,000 in 2030 for all filers regardless of income. It also phases down for modified AGI between roughly $500,000 and $600,000, reduced by 30% of income above the threshold, with a floor of $10,000. So high earners in high-tax states get a benefit that is both income-limited and time-limited, and, as one firm noted, the public will hear more about this the closer we get to 2029.

The senior deduction, an additional $6,000 for taxpayers 65 and older, phasing out above $75,000 MAGI ($150,000 joint), runs only from 2025 through 2028. The new deductions for tipped income up to $25,000, overtime up to $12,500, and auto-loan interest up to $10,000 on US-assembled vehicles are all temporary and income-limited.

Add it up and the planning calendar now has expirations in 2028, 2029, and 2030 rather than one in 2026. For anyone whose situation touches SALT, senior deductions, or the new income deductions, planning did not become simpler. It became a different, more granular scheduling problem, with more phaseout thresholds to model.

And one provision that made planning harder

Worth flagging because it cuts directly against the "easier" narrative: OBBBA introduced a new complication for charitable giving.

Beginning in 2026, for itemizers, only contributions exceeding 0.5% of adjusted gross income are deductible, a floor that did not previously exist. Taxpayers claiming the standard deduction are limited to $1,000, or $2,000 for married couples.

That floor changes charitable strategy in a specific way. Small annual gifts may now generate no deduction at all, which strengthens the case for bunching, concentrating several years of giving into one tax year to clear the threshold, and for donor-advised funds. Anyone who gives steadily and modestly each year and assumed the tax treatment was unchanged should check.

The genuinely new opportunities

Two provisions created planning options that did not exist before, and both are worth knowing.

The qualified small business stock rules under Section 1202 were expanded substantially, effective 2026: the holding period shortened from five years to three, the capital gain exclusion raised from $10 million to $15 million, and the gross asset limit to qualify raised from $50 million to $75 million, indexed for inflation. For founders and early employees of small companies, that is a meaningful change to exit planning.

And there is a new savings vehicle for children born between 2025 and 2028, structured as something between an IRA and a 529, with a $1,000 government deposit for eligible children, no income limits on eligibility, contributions up to $5,000 annually in after-tax dollars, employer contributions permitted, and access at 18 under traditional IRA rules. Details are still being worked out, which is itself a reason to watch rather than act hastily.

What a year of experience actually shows

The fair verdict is that OBBBA made one category of planning dramatically easier and left another more fragmented.

Estate planning is the clear winner. The threat that defined the field for nearly a decade is gone, the structural architecture survived intact, and families can now make gifting decisions based on their own circumstances rather than a countdown. That is a substantial improvement, and it explains the professional relief.

Income tax planning is a more mixed picture. Permanent brackets and a permanent QBI deduction are real simplifications. But the SALT phase-down, the temporary deductions with their own income thresholds, the charitable floor, and expirations spread across 2028 to 2030 mean the annual optimization work got more detailed, not less.

The practical takeaway is that the moment of maximum benefit for several of these provisions is now, not later. SALT relief, the senior deduction, and the tips, overtime, and auto-loan deductions all have end dates already on the calendar.

Knowing exactly when a benefit disappears is a much better problem than not knowing whether one will, which may be the most accurate summary of what changed.
