401(k) Secrets: What Most People Don’t Know About In-Service Withdrawals
Most people think they're locked into their 401(k) plan until they retire or leave their job. But if you're 59½ or older, you might have a powerful option...
When most people think about retirement risks, they worry about market crashes, healthcare costs, or running out of money. But one of the most dangerous — and least discussed — risks is timing risk.
The timing of when you retire can have a bigger impact on your financial future than almost anything else. With 2026 bringing new retirement contribution limits — like the $24,000 401(k) limit and $7,500 IRA limit — families planning retirement need to understand how market timing could derail even well-funded retirement accounts.
Here's why timing risk matters — and what you can do to protect yourself.

What Is Timing Risk?
Timing risk is the danger that you retire right before or during a market downturn — when your investments are temporarily down.
If you start pulling money from your portfolio while prices are low, you lock in losses you might otherwise have recovered from. This reduces the amount of assets you have left working for you — and increases the chances you'll run out of money sooner.
Even strong, diversified portfolios can get crushed if withdrawals start at the wrong time. This is particularly concerning for pre-retirees in California and other high-cost states, where larger withdrawal amounts may be necessary to maintain living standards.

Why It's So Dangerous
Early losses + withdrawals = double trouble.
When markets drop and you're still contributing to your accounts, it's not a huge problem — you're buying investments at lower prices. You might even be maximizing the new 2026 contribution limits, putting away $24,000 in your 401(k) or taking advantage of the enhanced catch-up contributions of $8,000 for those aged 60-63.
But once you retire and start taking money out, downturns are much harder to recover from. You're not adding new money — you're draining what's left.
If the first few years of your retirement are rough market years, your long-term success can be permanently damaged. This is especially critical given that the 2026 Social Security COLA increase of 2.5% may not keep pace with actual inflation, putting more pressure on your portfolio withdrawals.

Real-World Example
Imagine two retirees with identical $1.2 million portfolios in 2026. They both withdraw $48,000 a year (adjusted for inflation), plus they're paying the Medicare Part B premium of $194.50 per month.
- Retiree A experiences strong markets early on, with their portfolio growing despite withdrawals.
- Retiree B experiences a big market crash in the first two years, forcing them to sell investments at depressed prices.

How to Protect Yourself from Timing Risk
Hold 1–3 Years of Cash or Safe Assets: Having $50,000-150,000 in cash reserves or stable investments gives you breathing room during market declines. This might seem like a lot, but it's often less than what wealthy families will pay in estate taxes if they don't plan properly around the $13.99 million estate tax exemption.
Use Dynamic Withdrawal Strategies: Instead of rigidly withdrawing 4% every year, adjust your withdrawals based on market conditions. In strong years, you might take 4.5-5%. In weak years, you might temporarily reduce to 3-3.5%.
Harvest Strong Asset Classes First: During downturns, sell from the strongest-performing parts of your portfolio (maybe bonds or international stocks) while leaving beaten-down U.S. stocks alone to recover.
Consider Roth Conversions in Down Years: When your traditional IRA is temporarily depressed, converting to a Roth at lower values can provide tax-free growth potential and reduce future required distributions.
Stay Flexible: If needed, adjust your spending temporarily during rough patches. Delaying that major vacation or home renovation for 1-2 years can dramatically improve your long-term financial security.

You could experience the exact same average returns as someone else over 25 years, but if your good years happen late and your bad years happen early, you'll end up with significantly less money. This sequence-of-returns risk means that traditional retirement calculators that only show average returns can be dangerously misleading.
The solution isn't trying to time the market perfectly — it's building a withdrawal strategy that can adapt to whatever sequence of returns the market delivers.

Bottom Line
Timing risk is one of the biggest retirement threats — but it's also one of the most avoidable with the right strategy. With 2026's higher contribution limits and evolving tax landscape, now is the perfect time to stress-test your retirement income plan.
Building flexibility into your retirement withdrawal strategy can make the difference between just getting by and thriving for decades to come. A good financial plan isn't just about accumulating wealth — it's about creating a systematic approach to preserve and distribute that wealth regardless of market timing.
