OBBBA Impact on Retirees 65+: Senior Bonus, SALT Cap, Estate Exemption

TL;DR: The One Big Beautiful Bill Act (OBBBA) made the TCJA tax brackets permanent, added a $6,000-per-spouse senior bonus deduction phasing out from $150K to $250K MFJ MAGI, raised the SALT cap to $40,400 for MFJ, set the federal estate exemption at $15M per person, and made the Section 199A pass-through deduction permanent. The senior bonus phase-out creates a new effective marginal rate band between $150-250K MAGI that affects Roth conversion sizing.

What OBBBA actually changed for retirees

OBBBA's biggest impact on retirees comes from five specific provisions:

TCJA tax brackets made permanent. The seven-bracket structure (10/12/22/24/32/35/37%) was scheduled to sunset after 2025, reverting to pre-2018 brackets (15/28/31/36/39.6%). OBBBA made TCJA permanent.
Senior bonus deduction added. New $6,000-per-spouse standard deduction add-on for filers 65+. Phase-out begins at $75K MAGI Single / $150K MFJ; ends fully at $175K / $250K. Sunsets after 2028.
SALT cap raised to $40,400 (MFJ). Raised from $10,000 to $40,400 for MFJ filers in 2026. Phases down by income above thresholds. Reverts to $10,000 in 2030.
Estate exemption permanently $15M. Was scheduled to revert to ~$7M per person in 2026. OBBBA raised to $15M per person, indexed, permanent.
Section 199A QBI made permanent. The 20% pass-through deduction was also scheduled to sunset. Made permanent.

Combined, these represent the largest single tax-cut continuity for retirees in recent memory.

The senior bonus deduction — new $12K stack for MFJ both 65+

Each spouse age 65+ gets an additional $6,000 standard deduction. Both spouses 65+ = $12,000 of new MFJ deduction.

This stacks on the existing standard deduction ($32,200 MFJ in 2026) and the existing senior add-on ($1,650 per spouse 65+). For a couple both 65+ in 2026:

Component	Pre-OBBBA (2024)	Post-OBBBA (2026)
Standard deduction	$32,200	$32,200
Senior add'l (65+, each)	$1,650 × 2 = $3,300	$1,650 × 2 = $3,300
OBBBA senior bonus	$0	$6,000 × 2 = $12,000
Total deduction	$35,500	$47,500

The $12K bonus phases out 6%/$ above $150K MFJ MAGI — per spouse — so effectively 12%/$ for couples. Fully gone by $250K MFJ MAGI.

The new $150K-$250K donut hole

The phase-out structure creates a new effective marginal rate band that's meaningfully steeper than the bracket alone suggests. Every additional dollar of MAGI in the $150-250K range loses 12¢ of senior bonus deduction. At a 22% federal marginal rate, that's an extra 2.64% effective rate. At the 24% bracket (which kicks in at ~$211K MFJ taxable income), the senior bonus phase-out adds another 2.88%.

For retirees doing Roth conversions, this changes the bracket calculus:

Conversion that keeps you under $150K MAGI: full senior bonus captured. Marginal rate = bracket rate (e.g., 22%).
Conversion in the $150K-$250K range: bracket rate + ~2.6-2.9% phase-out drag. Effective marginal rate climbs to 24-27%.
Conversion above $250K MAGI: bonus is fully gone (the marginal drag is now zero again), but bracket rate is 32%.

The optimal conversion sizing under OBBBA often becomes: convert to fill the 22% bracket below $150K MAGI, OR convert aggressively above $250K MAGI to skip the phase-out entirely. The middle range is the donut hole.

Worked tax savings across income levels

Federal tax owed for an MFJ couple both 65+ at different total income levels, pre vs post OBBBA:

Total income	Pre-OBBBA tax	Post-OBBBA tax	OBBBA savings
$60,000	$2,940	$1,500	$1,440
$100,000	$7,740	$5,100	$2,640
$150,000	$18,540	$15,900	$2,640
$200,000	$29,540	$28,520	$1,020
$300,000	$55,290	$55,290	$0 (bonus phased out)

Middle-income retirees with $60K-$150K MFJ total income see $1,400-$2,640 of annual federal tax savings. Above $150K, savings shrink as the senior bonus phases out. By $250K-$300K, retirees are back to the pre-OBBBA tax level (the bonus is fully gone), but they still benefit from the permanent TCJA brackets, larger SALT cap, and permanent estate exemption.

The SALT cap change — relevant for high-tax-state retirees

TCJA originally capped State and Local Tax (SALT) deduction at $10,000 for both Single and MFJ. Painful for high-tax-state residents (California, New York, New Jersey).

OBBBA raised the cap to $40,400 for MFJ in 2026 (proportional for other statuses), with phase-down provisions for very-high-income filers and a sunset in 2030 reverting to $10,000.

For California retirees:

Couple owning home with $15K property tax + $20K CA state income tax + $5K registration = $40K of SALT. Old $10K cap disallowed $30K. New $40,400 cap allows the full $40K.
At the 24% bracket: ~$7,200 of additional itemized × 24% = ~$1,728/year of federal tax saved.
Retirees who weren't previously itemizing (because the old SALT cap kept their total below the standard deduction) may now flip back to itemizing — capturing previously-wasted charitable + mortgage interest deductions.

For any CA, NY, NJ, MA, or similar high-tax-state retiree, re-evaluate your itemize-vs-standard-deduct decision every year through 2029.

Estate planning gets simpler — $15M permanent

Under pre-OBBBA law, the federal estate tax exemption was scheduled to revert from ~$14M per person in 2025 to roughly $7M per person in 2026. OBBBA reset it to $15M per person, indexed for inflation, made permanent.

For a married couple using portability, combined federal exemption is now $30M, indexed upward. This effectively removes federal estate tax for the vast majority of American families. Less than 0.05% of estates will face federal estate tax under OBBBA permanence.

Planning shifts:

Lifetime gifting strategies become less urgent for estates under $30M.
Irrevocable life insurance trusts (ILITs) become more focused on liquidity and asset protection rather than estate tax minimization.
Income-tax-focused estate planning dominates. Inherited IRA 10-year rules, step-up basis on brokerage, Roth conversion timing matter more than federal estate tax minimization for most retirees.
State estate tax still matters in 12+ states. California is NOT one of them, but New York, Massachusetts, Washington, Oregon have state-level estate taxes with much lower exemptions ($1M-$7M).

Frequently Asked Questions

What is OBBBA?

The One Big Beautiful Bill Act, enacted in 2025, is comprehensive tax legislation that made most of the Tax Cuts and Jobs Act (TCJA) brackets permanent, added a senior bonus deduction, raised the SALT cap, set the federal estate exemption at $15M permanently, and made the Section 199A pass-through deduction permanent.

What is the OBBBA senior bonus deduction?

A $6,000-per-spouse additional standard deduction for filers age 65+. MFJ couples both 65+ get $12,000 combined. Phases out 6%/$ above $150K MFJ MAGI — per spouse, so 12%/$ for couples. Fully gone at $250K MFJ MAGI. Sunsets after 2028.

Did OBBBA make the SALT cap larger?

Yes — raised from $10,000 to $40,400 for MFJ filers in 2026, with phase-downs for very high incomes. Reverts to $10,000 in 2030. Big benefit for high-tax-state retirees.

What is the 2026 federal estate exemption?

$15M per person, indexed for inflation, made permanent by OBBBA. For a married couple using portability, $30M combined. Removes federal estate tax exposure for virtually all American families.

Did OBBBA change Social Security taxation?

Not directly. The provisional income formula and SS taxation tiers were unchanged. Indirectly, the senior bonus deduction reduces taxable income for many retirees — which can reduce provisional income and resulting SS taxation, but the underlying rules are the same.

Does the senior bonus deduction sunset?

Yes — scheduled to sunset after 2028. The other OBBBA provisions (TCJA bracket permanence, $15M estate exemption, 199A permanence) are permanent. The SALT cap reverts to $10K in 2030. The senior bonus is the shortest-lived major provision.
