If you've been reading financial articles published in late 2025, you probably saw warnings like "tax brackets are reverting to pre-2017 levels in 2026" or "the TCJA sunset means higher taxes for everyone."
Those warnings were valid — at the time. But they're wrong now, and the misinformation is still circulating months later. Financial advisors, blog posts, and even some professional planning tools are still operating on outdated assumptions. If you're making Roth conversion decisions or retirement withdrawal plans based on "higher 2026 brackets," you could be leaving money on the table.
Here's what actually happened.
The Tax Cuts and Jobs Act of 2017 lowered individual tax brackets from their 2017 levels. The 25% bracket dropped to 22%. The 28% bracket dropped to 24%. The top rate went from 39.6% to 37%. These were scheduled to expire after December 31, 2025.
That expiration would have been significant. A married couple in the 22% bracket would have jumped to 25%. The standard deduction would have shrunk. Millions of households would have seen higher tax bills.
But on July 4, 2025, the One Big Beautiful Bill Act (OBBBA) was signed into law. Among its many provisions, it permanently extended the TCJA individual tax brackets with inflation indexing. The rates didn't sunset. They didn't revert. The 10%, 12%, 22%, 24%, 32%, 35%, and 37% brackets are still in effect for 2026 and beyond.
| Rate | Taxable Income |
|------|---------------|
| 10% | $0 – $24,900 |
| 12% | $24,901 – $101,400 |
| 22% | $101,401 – $198,300 |
| 24% | $198,301 – $390,050 |
| 32% | $390,051 – $411,800 |
| 35% | $411,801 – $475,050 |
| 37% | Over $475,050 |
These are the TCJA rates with 2026 inflation adjustments. Not the pre-2017 rates. Not "reverted" rates.
While the tax brackets stayed the same, something else did change — and it's arguably more impactful for early retirees:
The enhanced ACA premium subsidies expired on December 31, 2025.
The Inflation Reduction Act had expanded ACA subsidies so that households above 400% of the Federal Poverty Level could still receive premium assistance. That expansion is gone. The subsidy cliff is back.
What does this mean in practice? A married couple earning $84,601 in 2026 — just $1 over the 400% FPL threshold — loses ALL premium subsidies. The typical cost: $15,000 to $22,000 per year in lost healthcare subsidies.
That's not a tax bracket change. It's a benefits cliff. And it requires a completely different planning response.
Here's where the misinformation causes real financial harm:
Scenario 1: The unnecessary Roth conversion rush. If you believe brackets are higher in 2026, you might have rushed to do large Roth conversions in late 2025 at what you thought were "lower rates." But the rates are the same. Those conversions may have pushed you over the ACA cliff, costing $22,000 in subsidies to save a few hundred in future taxes.
Scenario 2: The overly conservative withdrawal plan. If your tax planning software assumes 2026 brackets reverted to 25%/28%/33%, it's calculating your tax liability too high. Your "safe" withdrawal amount is actually more conservative than necessary, which means you're either spending less than you could or converting less to Roth than you should.
Scenario 3: The missed Roth conversion window. The real opportunity in 2026 isn't "convert before brackets go up" — it's "convert up to the ACA cliff threshold while brackets are still at TCJA levels." For a married couple with no other income, that's roughly $101,400 in the 12% bracket before touching 22%. Fill the 12% bracket with Roth conversions, stay under 400% FPL ($84,600 for a couple), and you get both: low tax rates AND full ACA subsidies.
The planning challenge for 2026 isn't "higher brackets." It's the interaction between stable brackets and the returned subsidy cliff. You need to optimize across three dimensions simultaneously:
These three systems interact in non-obvious ways. A Roth conversion that saves $3,000 in future taxes might cost $22,000 in lost ACA subsidies today. An HSA contribution reduces MAGI dollar-for-dollar, creating Roth conversion headroom without triggering the cliff.
This is exactly the kind of multi-variable optimization that a Monte Carlo retirement calculator with ACA cliff awareness is built to handle. Simple spreadsheets that model tax brackets in isolation will miss these interactions entirely.
Your 2026 tax brackets are the same TCJA rates you've had since 2018, adjusted for inflation. They did not revert. The One Big Beautiful Bill Act made them permanent.
What did change is the ACA subsidy landscape — and that's where the real planning opportunity lies. If you're an early retiree managing income between retirement and Medicare, the subsidy cliff is your primary constraint, not the bracket boundaries.
Plan accordingly. And verify that whatever tool or advisor you're using has updated their 2026 assumptions.
