Over my years helping folks plan for retirement, I’ve noticed how small tweaks to a 401(k) can make a big difference down the road. With changes rolling out this year, now is the time to review your allocations. Markets shift, rules update, and tax landscapes evolve, all of which call for action before the end-of-year rush.
October gives you a clear window to adjust without holiday distractions or last-minute deadlines. Sticking with outdated setups risks missing opportunities or facing surprises. Let’s look at the key reasons to rebalance your portfolio now.
New Roth Catch-Up Rules Hit High Earners

If you earn over $150,000 in FICA wages from last year, your catch-up contributions must go into a Roth 401(k) this year.[1][2] This means paying taxes upfront instead of deferring them. Reallocating some pre-tax funds to Roth now builds tax-free growth for later. Many clients overlook this until tax time hits.
Plans without Roth options might block catch-ups altogether. Check your plan details soon. Shifting allocations early smooths the transition.[3]
Higher Contribution Limits Open Doors

The standard deferral limit rose to $24,500 this year, up $1,000 from 2025.[4] Catch-up for those 50-plus is now $8,000. This lets you sock away more, but only if your allocation matches your goals. Rebalancing ensures you’re not overweight in one area.
Nearly half of high earners maxed out last year, per Vanguard data.[1] Adjust before October to capture the full benefit. It keeps your savings on track amid rising costs.
Super Catch-Up Boost for Ages 60 to 63

Folks in this age group get $11,250 in catch-up room, on top of the base limit.[4] That’s a hefty $35,750 total potential. Reallocating to leverage this means prioritizing Roth if you’re a high earner. It sets up tax-free withdrawals later.
Many plans allow it, but confirm yours does. Act before year-end deadlines. This window closes fast as retirement nears.
TCJA Sunset Means Higher Taxes Ahead

Provisions from the 2017 tax law expire this year, pushing rates up for many brackets.[5] Standard deductions drop too. Converting traditional 401(k) to Roth now locks in lower rates. Reallocation helps diversify your tax exposure.
Expect top rates near 40% post-sunset. Clients who planned early avoided bigger bills. Review your mix today.
Market Drift Demands Rebalancing

Strong stock gains last year likely skewed your allocations toward equities.[6] Rebalancing sells high and buys low. It manages risk without timing the market. Do it before October volatility spikes.
Thresholds like 5% drift signal action. Portfolios off-target grow riskier over time. Steady clients see better long-term results.
Plan Amendments Loom by Year-End

Employers must update 401(k) plans for SECURE 2.0 by December 31.[7] Changes could affect options. Reallocate now to lock in current choices. Avoid disruptions later.
Some extensions exist, but most hit the deadline. Check with HR soon. Proactive steps keep you flexible.
Diversify Tax Buckets for Flexibility

Mix pre-tax, Roth, and after-tax wisely.[3] Roth portions dodge future RMDs. Rebalancing builds this blend. It eases withdrawals in retirement.
High earners benefit most from Roth shifts. Projections show tax savings. Start small if needed.
Prep for Year-End Contribution Push

Max contributions by December 31.[8] Reallocate to fund the increase. October avoids payroll crunches. It maximizes matches too.
Average savings rates hover around 12%.[1] Bump yours up. Steady growth compounds hugely.
Manage Volatility in Uncertain Times

Mid-year markets showed swings. Rebalancing restores your risk level.[6] Closer to retirement, dial back stocks. Before October keeps emotions in check.
Quarterly checks work for many. Align with your timeline. Peace of mind follows.
Align with Your Retirement Horizon

As goals shift, so should allocations. Younger savers tilt growth; near-retirees favor stability. Review now for personalized fit.
I’ve guided hundreds through this. Small changes yield big security. Your future self thanks you.
Reallocating your 401(k) before October positions you for these shifts without stress. Take stock of your situation, run the numbers, and make moves that fit your life. A balanced approach today builds lasting retirement strength.
