The One Big Beautiful Bill, signed by President Donald Trump, officially reshapes the U.S. tax system beginning with the 2026 tax season. These changes affect all taxpayers, but they have deep and direct impact on adults over 50, especially retirees and near-retirees ages 60+, 65+, and 70+ who rely on Social Security, Medicare, pensions, IRAs, home equity, or investment income.
Below are 17 important tax changes, clearly explained with practical examples for single individuals and married couples at different ages.
🔵 1. Increased Standard Deduction by Age: 60+, 65+, 70+
The new law creates three age-based tiers:
- Age 60–64: +$1,200
- Age 65–69: +$2,500
- Age 70+: +$3,800
Example
- Single taxpayer age 70+: additional $3,800 in standard deduction
- Married couple both 70+: additional $7,600
🔵 2. Higher Income Threshold Before Social Security Is Taxed
Social Security becomes non-taxable unless income exceeds:
- Single: $40,000
- Married: $70,000
Example
Married couple (age 70+): Social Security $45,000 + IRA $20,000 = $65,000
→ 0% Social Security tax
🔵 3. Required Minimum Distribution (RMD) Age Increased to 76
Retirees gain one extra year before mandatory IRA/401(k) withdrawals begin.
Benefits
- More “tax-gap years” for Roth conversions
- Reduces IRMAA risk
🔵 4. New 20% Long-Term Care (LTC) Tax Credit
- Maximum eligible LTC expenses: $10,000
- Maximum credit: $2,000 per year
Example
Age 75, spends $8,000 on home care → receives $1,600 tax credit
🔵 5. New 1.5% Investment Surtax for High-Income Households
Applies to:
- Singles above $250,000
- Married couples above $450,000
Example
Sell an investment property with $300,000 gain → $50,000 subject to the 1.5% surtax
🔵 6. Federal Estate Tax Exemption Increased to $14.5 Million Per Person
Married couples → $29 million exemption.
Impact
Most middle- and upper-middle-class families avoid federal estate taxes.
🔵 7. Medicare IRMAA Thresholds Increased by 15%
Retirees get more flexibility to withdraw IRA funds without triggering higher Medicare Part B & D premiums.
🔵 8. Expanded Catch-Up Contributions for Age 60–64
Workers age 60–64 can contribute 50% more in retirement catch-up contributions than before.
Example
A 62-year-old still working can reduce taxable income by contributing more to 401(k) or 403(b).
🔵 9. Higher HSA Contribution Limits for Adults 65+
- Age 55–64: +$1,000
- Age 65+: +$2,000
🔵 10. Qualified Charitable Distribution (QCD) Limit Increased to $125,000 Per Person
Adults 70½+ can give directly from IRAs to charity, reducing both taxes and future RMDs.
Example
Married couple age 70+: can donate up to $250,000 per year through QCD.
🔵 11. New 10% Property Tax Credit for Homeowners 65+
Maximum annual credit: $1,500
Example
70-year-old homeowner paying $6,000 in property taxes → receives $600 tax credit
🔵 12. Faster Long-Term Capital Gains (LTCG) Treatment for Adults 65+
Adults 65+ qualify for long-term capital gains tax after only 12 months, even if the sale occurs within 1 year.
🔵 13. Higher Earnings Allowance for Early Retirees (Ages 62–66)
Income threshold increased to about $26,000
→ Working seniors no longer lose Social Security benefits for modest part-time earnings.
🔵 14. Widow/Widower Protection Rule for Age 70+
Surviving spouses may keep the Married Filing Jointly tax brackets for 2 additional years after their partner passes away.
Benefits
- Prevents sudden tax hikes
- Reduces risk of Medicare IRMAA penalties
🔵 15. Temporary SALT Cap Increase for High-Tax States
Homeowners in states like CA, NY, NJ, IL, MA receive temporary relief through a higher state & local tax deduction cap.
🔵 16. Charitable Deduction Restrictions Starting in 2026
- High-income taxpayers: charitable deduction capped at 35%
- New “deduction floor” of 0.5% AGI
→ Small donations no longer deductible unless exceeding the minimum threshold.
🔵 17. New 1099-K Rules and 1% Tax on Certain International Transfers
- Tighter 1099-K reporting for online sales/payments
- A new 1% tax on certain foreign remittances
→ Affects retirees who send money abroad or sell items online.
🟦 How These Rules Affect Different Age Groups
Ages 60–64
Benefits
- Higher catch-up contributions
- More Roth conversion opportunities
- Lower likelihood of Social Security taxation
Watch Out
- If still working with investment income, may hit the 1.5% surtax
Ages 65–69
Benefits
- Higher standard deduction
- Higher HSA contributions
- QCD useful for tax reduction
- IRMAA relief
Watch Out
- Careful planning needed when selling investment properties
Ages 70+
