The tax sunset that wasn’t (and the new rules for age 55+)
Congress locked in the individual tax brackets—plus a temporary bonus deduction for age 65+.
For the last 3 years, nearly every financial planner, tax accountant, and retirement podcast repeated the same urgent warning:
“Convert your traditional IRAs to Roth immediately. On December 31, 2025, the 2017 tax cuts expire, and brackets will automatically jump from 12%, 22%, and 24% back to 15%, 25%, and 28%.”
Retirees scrambled to accelerate income, dreading a steep tax hike across their balance sheets.
Then Washington did what Washington often does at the midnight hour: they passed tax reconciliation legislation that fundamentally altered the playbook.
The scheduled reversion to pre-2018 brackets was canceled. The individual income tax brackets (10%, 12%, 22%, 24%, 32%, 35%, and 37%) have been permanently locked in.
However, along with locking in those rates, Congress introduced new thresholds, modified the standard deduction, and added a temporary “bonus deduction” aimed directly at older adults.
This week, we audit the updated tax landscape, dispel the lingering sunset panic, and map out your strategic conversion window between now and age 73.
The Reality: Where 2026 Tax Brackets Actually Sit
Rather than jumping up to 15%, 25%, and 28%, federal income tax brackets remain anchored to the familiar tiers.
For the 2026 tax year, taxable income thresholds (after deductions) are:
| Tax Rate | Single Filers | Married Filing Jointly |
|---|---|---|
| 10% | $0 to $12,400 | $0 to $24,800 |
| 12% | $12,401 to $50,400 | $24,401 to $100,800 |
| 22% | $50,401 to $105,700 | $100,801 to $211,400 |
| 24% | $105,701 to $201,775 | $211,401 to $403,550 |
| 32% | $201,776 to $256,225 | $403,551 to $512,450 |
| 35% | $256,226 to $640,000 | $512,451 to $768,700 |
| 37% | $640,601+ | $768,701+ |
(Data source: 2026 IRS adjustments.)
The standard deduction also stayed elevated: $16,100 for single filers and $32,200 for married couples filing jointly.
The Big Win: The Age 65+ “Bonus Deduction”
Here is the provision most retirees have not factored into their 2026 numbers: a temporary bonus deduction for older adults.
In addition to the standard deduction and the existing extra age deduction ($1,650 to $2,050 for those 65+), taxpayers aged 65 and older receive an additional $6,000 bonus deduction per person:
- Single (Age 65+): Can deduct up to $24,750 before paying a single dollar in federal income tax.
- Married Couple (Both Age 65+): Can deduct up to $48,300 off their household income.
The Phase-Out Trap
This bonus deduction comes with an income test. It begins phasing out at:
- $75,000 for single filers (fully phased out at $175,000).
- $150,000 for joint filers (fully phased out at $250,000).
Crucially: this $6,000 bonus deduction is temporary and scheduled to expire after 2028. That creates a specific 3-year tactical window for anyone currently 65 or older.
The New Playbook: What to Do with Your Roth Conversions
Because rates did not revert to 28% or 33% across the board, the frantic rush to convert an entire 401(k) or IRA overnight is off the table.
Panic conversions often trigger unintended penalties: pushing income past the ACA subsidy cliff ($62,600 single / $85,000 couple) if under 65, or triggering higher Medicare IRMAA surcharges if 63 or older.
Instead, shift to a calculated, low-bracket “sip” strategy:
1. Fill the 12% Bracket to the Rim
For a married couple, the 12% bracket extends to $100,800 of taxable income. With the $32,200 standard deduction, you can bring in $133,000 in gross household income and never pay more than 12% on your marginal dollars.
If your baseline pension or portfolio withdrawals total $80,000, you have roughly $53,000 of room to execute Roth conversions at a modest 12% tax rate.
2. Exploit the 24% Ceiling Before Age 73
For higher-balance savers, the 24% bracket remains a massive runway, topping out at $403,550 for married couples.
Once you cross into the 32% bracket, your tax cost jumps by 8 percentage points immediately. If you have large pre-tax balances that will trigger massive Required Minimum Distributions (RMDs) at age 73 or 75, peeling off conversions up to the top of the 24% bracket ($201,775 single / $403,550 joint) protects your heirs from inheriting an accelerated 10-year tax bomb.
3. Harvest the 65+ Bonus Deduction Window (2026–2028)
If you are between 65 and 72 with moderate income, use the extra $6,000 to $12,000 standard deduction to absorb Roth conversion income tax-free before the bonus provision sunsets in 2028.
Your Action Item for This Week
- Review your projected 2026 gross income against the standard deduction ($16,100 single / $32,200 married).
- If you are 65+, factor in whether your income qualifies you for the extra $6,000 (or $12,000 joint) bonus deduction.
- Calculate the exact dollar gap between your current taxable income and the top of your target bracket (either the 12% ceiling at $100,800 or the 22% ceiling at $211,400 for joint filers).
That gap represents your safe conversion capacity for the year.
