Sunset Averted: How the One Big Beautiful Bill Made the TCJA Rates and Section 199A Permanent

What the law did

The One Big Beautiful Bill Act (OBBBA), Public Law 119-21, was signed into law on July 4, 2025. A drafting note worth recording: the marquee short title was struck on a procedural point during Senate reconciliation, so the enacted statute technically carries no official short title — but it is universally referred to as OBBBA, including in IRS materials, and we use that name here.

On the two provisions that drove half a decade of "act before the sunset" planning, the law is direct.

The individual rate structure is permanent. The seven brackets of 10, 12, 22, 24, 32, 35, and 37 percent are now permanent, and the scheduled reversion is gone. Absent this law, the top rate would have returned to 39.6 percent on January 1, 2026, and the lower brackets would have shifted with it. That reversion will not happen. The increased standard deduction was also made permanent, and was enhanced for 2025 to $15,750 for single filers and $31,500 for married couples filing jointly.

The Section 199A deduction is permanent. The 20 percent deduction for qualified business income under IRC § 199A no longer expires after 2025. One point deserves emphasis because an earlier version of the bill said otherwise: the rate stayed at 20 percent. A House-passed draft proposed raising it to 23 percent, and that increase did not survive into the enacted law. The deduction is permanent at 20 percent.

OBBBA also improved the mechanics of § 199A, effective for tax years beginning after December 31, 2025. The phase-in range over which the wage and specified-service limitations apply widened from $50,000 to $75,000 for single filers, and from $100,000 to $150,000 for joint filers. And the law added a new minimum deduction of $400 for taxpayers with at least $1,000 of qualified business income from an active trade or business in which they materially participate, with both figures indexed for inflation after 2026.

The distinction that matters for 2025 versus 2026

There is a subtlety here that determines how to read the change correctly, and getting it wrong leads to overstating what happens this year.

For tax year 2025, almost nothing about the rates or § 199A is different from what it would have been anyway. The Tax Cuts and Jobs Act rates were already in effect for 2025 under prior law, and § 199A already applied for 2025. What OBBBA did for 2025 was permanence — it ensured the 2026 reversion never arrives. The one change taxpayers actually feel on a 2025 return is the enhanced standard deduction, which applies this year.

For tax year 2026 and beyond, the structural improvements to § 199A take effect: the wider phase-in ranges and the new minimum deduction. So the accurate way to describe the achievement is twofold. In 2025, the deduction and rates are saved from extinction. In 2026, the deduction's rules get better. Conflating the two — for instance, claiming the wider phase-in applies to 2025 returns — is the predictable error, and it is wrong.

What this means for planning

The strategic shift is larger than any single provision. For five years, a substantial body of planning was organized around a deadline: accelerate income into lower-rate years, restructure entities before the QBI deduction vanished, make irreversible moves because the window was closing. That entire frame is now obsolete for these provisions. The window is not closing. It is open and, as enacted, indefinite.

This is liberating and slightly disorienting at once. Plans built to beat a sunset were, by necessity, compressed and sometimes suboptimal — taken on the clock rather than on the merits. With the clock removed, the better posture is to re-evaluate those plans on their own terms. An entity structure adopted primarily to lock in § 199A before 2026 should be reassessed for whether it still fits the business now that the deduction is permanent. Income-timing strategies premised on a rate increase that is no longer coming should be unwound or rebuilt.

Permanence in tax law is, of course, permanence until Congress legislates again — no statute binds a future Congress. But "permanent" here means there is no scheduled expiration to plan against, which is a materially different planning environment than a dated sunset. The defensible response is to stop optimizing for a deadline that no longer exists and start optimizing for the durable structure that now governs.

Key takeaways

• OBBBA (Pub. L. 119-21), signed July 4, 2025, made the TCJA individual rate brackets (10–37 percent) permanent and made the increased standard deduction permanent, with 2025 amounts of $15,750 single and $31,500 joint.
• The Section 199A qualified business income deduction is permanent at 20 percent; the proposed increase to 23 percent in an earlier draft was not enacted.
• Effective for 2026, the § 199A phase-in ranges widen to $75,000 (single) and $150,000 (joint), and a new $400 minimum deduction applies to taxpayers with at least $1,000 of active QBI.
• For 2025, the practical change taxpayers feel is the enhanced standard deduction; the rest is permanence (no 2026 cliff) and improved § 199A rules that begin in 2026.

Frequently asked questions

Does the higher Section 199A phase-in range apply to my 2025 return?

No. The wider phase-in ranges ($75,000 single / $150,000 joint) and the new $400 minimum deduction are effective for tax years beginning after December 31, 2025 — so 2026 returns. For 2025, § 199A operates under the prior phase-in figures.

Is the QBI deduction 20 percent or 23 percent?

It is 20 percent. An earlier House version of the bill proposed 23 percent, but the enacted law retained the 20 percent rate and made it permanent.

Should I unwind planning I did to beat the sunset?

It depends on what the planning was for. Moves taken primarily because § 199A or the lower rates were expiring should be re-examined now that both are permanent — some will still make sense on the merits, and some were driven mainly by the deadline that no longer exists.

Bottom line

The long-feared TCJA sunset is gone for the individual rates and § 199A. The right reaction is not to do nothing — it is to retire deadline-driven planning and rebuild around a code that, as enacted, has no expiration date for these provisions. For most owners and families, that means reassessing decisions made under time pressure rather than continuing to plan against a cliff that has been removed.
