Workers nearing retirement who need to understand how 2026 changes affect retirement account contributions and withdrawal planning
Retirement-focused changes for 2026
The 2026 adjustments include several provisions specifically beneficial for pre-retirees and early retirees.
New super catch-up provision
Ages 60-63 can now contribute $34,750 to 401(k) plans (up from $30,500). This "super catch-up" recognizes that these years are often peak earning and peak saving years before retirement.
For someone in the 24% bracket, this extra $4,250 contribution saves $1,020 in current taxes while boosting retirement savings.
IRA contribution increases
Traditional and Roth IRA limits increased to:
Even if you have a 401(k), you can still contribute to IRAs if your income is below the phase-out thresholds (which also increased with inflation).
HSA planning for healthcare costs
HSA limits increased to $4,300 (individual) and $8,550 (family). If you're eligible, HSAs provide triple tax benefits:
1. Tax-deductible contributions
2. Tax-free growth
3. Tax-free withdrawals for medical expenses (or penalty-free after age 65)
Withdrawal planning implications
Higher tax brackets mean you can withdraw more from traditional retirement accounts while staying in the same tax bracket:
This creates opportunities for tax-efficient retirement income strategies and Roth conversion ladders.
Key takeaway: Ages 60-63 can now contribute $34,750 to 401(k)s, while higher bracket thresholds provide $3,750-$7,975 more room for tax-efficient retirement withdrawals.
