OBBBA Retirement Planning 2026: What the New Tax Law Means for Retirees
The One Big Beautiful Bill Act, signed July 4, 2025, is the most significant tax legislation for retirees since the SECURE Act. It adds a brand-new $6,000 senior deduction for ages 65 and older, permanently locks in the $15 million estate exemption, and makes key deductions permanent that affect retirees with rental or business income. Here's what changed — and what didn't — for your retirement plan.
OBBBA Senior Deduction Calculator
The new $6,000 senior deduction reduces your taxable income — not your AGI. That means it cuts your federal income tax bill directly, but does not lower MAGI for IRMAA, Social Security taxation, or ACA purposes. Use this calculator to estimate your benefit for 2025–2028.1
2026 Senior Deduction Estimator
The $6,000 Senior Bonus Deduction 2025–2028
What it is: Taxpayers who are age 65 or older as of December 31 may claim an additional deduction of $6,000 per qualifying person on their federal return. A married couple where both spouses are 65+ can claim $12,000 combined.1
Phase-out: The deduction begins to phase out when MAGI exceeds $75,000 for single filers ($150,000 for married filing jointly) and is fully eliminated at $175,000 ($250,000 MFJ). The reduction is linear: for every dollar of MAGI above the threshold, you lose $0.06 of deduction (6 cents per dollar for single; same effective rate per-dollar for MFJ). The phase-out applies per tax return, not per person — so a couple with two qualifying spouses sees the full $12,000 phase out across the same $100,000 income range.2
Key mechanics:
- Available to both itemizers and standard-deduction filers — it stacks on top of either approach
- Each qualifying spouse gets their own $6,000; one 65+ spouse in a joint return = $6,000 total; both 65+ = $12,000
- Reduces taxable income, not AGI/MAGI — so it has no effect on IRMAA, Social Security provisional income, ACA subsidies, or Roth IRA phase-outs
- Available for tax years 2025 through 2028 only — not permanent
| Scenario | Max deduction | Phase-out range | At 22% bracket |
|---|---|---|---|
| Single filer, 65+ | $6,000 | $75K – $175K MAGI | Up to $1,320/yr savings |
| MFJ, one spouse 65+ | $6,000 | $150K – $250K MAGI | Up to $1,320/yr savings |
| MFJ, both spouses 65+ | $12,000 | $150K – $250K MAGI | Up to $2,640/yr savings |
Four-year total potential: A couple where both spouses are 65+ and MAGI is under $150,000 can claim $12,000/year × 4 years = $48,000 in extra deductions. At a 12% rate that's $5,760 saved; at 22% it's $10,560. Not a retirement-defining number, but meaningful — roughly the cost of one year of Medicare Part B premiums plus IRMAA surcharges for many couples.
Estate Tax: Permanent $15M Exemption Permanent
OBBBA permanently raised the federal estate, gift, and generation-skipping transfer (GST) exemption to $15 million per person ($30 million for married couples using portability) beginning in 2026, and indexed it for inflation going forward.3 The TCJA exemption was scheduled to sunset at the end of 2025 to approximately $7–8 million — that sunset is now dead.
What this means for retirees:
- No urgency to gift before year-end. The "use it or lose it" pressure that drove aggressive gifting strategies in 2024–2025 is gone. Annual gift exclusion ($19,000/recipient in 2026) remains useful for estate reduction but is no longer a race against a sunset.
- Portability election still matters. Estates under $15M per spouse should still file a federal estate tax return (Form 706) within 9 months of the first spouse's death to preserve the unused exemption for the survivor, even though the risk of estate tax exposure is greatly reduced for most families.
- Irrevocable trusts already funded may be worth revisiting. If you transferred assets into a SLAT or other irrevocable trust specifically to lock in the old exemption before the sunset, that planning is no longer necessary for new assets — talk to your estate attorney about current strategy.
- Estate planning still matters below $15M. Probate, incapacity planning (durable POA, healthcare proxy), beneficiary designations, and trust structures are valuable regardless of estate tax exposure.
§ 199A QBI Deduction Made Permanent Permanent
The Section 199A qualified business income (QBI) deduction — up to 20% of qualified business income from pass-through entities — was set to expire at the end of 2025. OBBBA made it permanent with slightly expanded phase-in ranges ($25,000 more for non-joint returns, $50,000 more for joint returns) and added a minimum $400 deduction for taxpayers with at least $1,000 in qualified business income.4
Relevant for retirees who have:
- Rental income qualifying as a trade or business. Rental properties meeting the IRS "trade or business" standard (generally 250+ hours of rental activity per year, with documentation) can generate QBI. On $60,000 of net rental income, a 20% deduction = $12,000 off taxable income.
- Consulting or freelance income in retirement. Many retirees earn part-time income from a sole proprietorship or LLC — that income typically qualifies for the QBI deduction.
- Partnership or S-corp distributions. Business owners who retained equity in a pass-through entity continue to receive QBI treatment on their share of business income.
Note: W-2 wages, Social Security, pension payments, RMDs, interest, dividends, and capital gains do NOT qualify as QBI. The deduction only applies to income from a trade or business.
100% Bonus Depreciation Made Permanent Permanent
OBBBA permanently restored 100% first-year bonus depreciation for qualified property placed in service on or after January 19, 2025.4 The TCJA provision had been phasing down — 80% in 2023, 60% in 2024 — and was expected to reach zero. It is now permanently at 100%.
Relevant for retirees with real estate investments: Retirement-age real estate investors who purchase rental properties (personal property, improvements, certain land improvements) or short-term rentals can now elect to deduct the full cost in year one rather than depreciating over 27.5 or 39 years. This can create substantial paper losses in the year of purchase, which — depending on your passive activity status — may offset other income or create a loss carryforward.
Important caveat: Bonus depreciation creates a timing benefit, not a permanent one. Deducting now means less basis and larger gain (or recapture) later. Discuss the long-term tax math with your advisor before treating bonus depreciation as purely a benefit.
What OBBBA Did NOT Change for Retirees
Several widely-publicized proposals either didn't make the final bill or were addressed through other mechanisms:
| Topic | What retirees heard | What OBBBA actually did |
|---|---|---|
| Social Security taxation | "No tax on Social Security" | No change. SS benefits are still taxed under IRC § 86 (up to 85% for high earners). The $6,000 senior deduction indirectly reduces taxable income for some retirees, but the SS provisional income thresholds — unchanged since 1984/1993 — remain in place.5 |
| RMD rules | No proposed change | Unchanged. RMD ages remain 73 (born 1951–1959) and 75 (born 1960+) per SECURE 2.0. Roth 401(k) lifetime RMD exemption (§ 325) remains in effect starting 2024. |
| 401(k) / IRA contribution limits | No change | Unchanged. 2026 limits: IRA $7,500 / $8,600 catch-up (50+); 401(k) $24,500 / $32,500 (50+) / $35,750 (60–63 super catch-up) per IRS Notice 2025-67. |
| Medicare / IRMAA | No proposed change | Unchanged. 2026 Part B base premium $202.90/mo; IRMAA tiers begin at $109,000 single / $218,000 MFJ. |
| Capital gains tax rates | No change at signing | Unchanged. 2026 0% LTCG thresholds: $49,450 single / $98,900 MFJ taxable income. |
How to Rethink Your Retirement Plan with OBBBA
The senior deduction doesn't solve IRMAA
The most important planning nuance: the $6,000 deduction reduces taxable income, not MAGI. Medicare Part B and D surcharges, Social Security benefit taxation, and ACA subsidy calculations all use MAGI. If you're near an IRMAA cliff — particularly the Tier 1 threshold at $218,000 MFJ in 2026 — the senior deduction gives you no room. To manage MAGI, the tools are: QCDs (reduce MAGI dollar-for-dollar up to $111,000 in 2026), HSA contributions before Medicare enrollment, and Roth conversion timing to avoid pushing MAGI over IRMAA thresholds.
Roth conversion planning in the OBBBA era
The senior deduction creates additional room in your lower tax brackets for the 2025–2028 window. A couple where both spouses are 65+ with MAGI under $150,000 gets $12,000 of extra taxable income shielded per year. This isn't MAGI reduction — but it does let you convert slightly more of a traditional IRA before hitting the 22% bracket. Combined with the permanent estate exemption (which reduces the urgency to convert large sums for estate reasons), the Roth conversion calculus becomes: optimize for your own lifetime tax, not for the estate.

Estate planning: revise your plan if the sunset drove your strategy
If your estate plan was built around aggressively gifting before the 2025 TCJA sunset — SLATs, 529 superfunding, irrevocable life insurance trusts funded with large gifts — you should re-examine whether the ongoing strategy still fits your goals. The exemption is now permanent at $15M. Gifting remains useful for removing appreciation from your estate, but the fire-sale urgency is gone. Review beneficiary designations, consider whether any irrevocable structures created complexity you no longer need, and re-check portability election status.

For real estate investors: bonus depreciation is a timing tool, not a freebie
100% bonus depreciation is now permanent. For retirement-age investors buying rental property, this means you can choose to front-load depreciation into year one. Useful if: (a) you have offsetting passive income, (b) you're in a high bracket now and expect to be lower later, or (c) you plan to step up basis via a 1031 exchange or hold until death. Less useful if you're already in a low bracket and the deduction simply creates a carryforward loss you may never use.
How a retirement advisor uses OBBBA in your plan
The OBBBA provisions interact with each other and with your existing RMD, Roth conversion, IRMAA, and estate planning decisions in ways that aren't obvious from the individual provisions. A retirement-income specialist can model the 2025–2028 senior deduction window alongside your Roth conversion ladder, identify whether your rental income qualifies for QBI treatment, and update your estate plan now that the sunset is off the table.
