Leaving a job, whether you’re retiring, changing careers, or simply moving on, often comes with one big financial question: What should you do with your 401(k)?
This decision matters more than most people realize. The way you handle a rollover can affect your taxes, your investment options, and even your ability to use certain planning strategies in the future. Below is a clear, practical guide to help you make informed decisions and avoid the pitfalls we see far too often.
The Rule of 55: A Helpful Option for Early Retirees
If you separate from service in or after the year you turn 55, you may be able to take withdrawals from your existing 401(k) without the 10% early-withdrawal penalty. This can be an important bridge strategy if you retire earlier than expected or need flexibility during the transition. However, once you roll your 401(k) into an IRA, you lose this provision. So before you roll anything over, ask yourself...Will I need access to this money before age 59½? If the answer could be yes, leaving the money in your employer plan for a short time could be beneficial.
Traditional Retirement: Why Many People Roll Over at 59½
Once you reach age 59½, your options expand. This is typically when a rollover to an IRA makes sense because it gives you:
- More control over tax withholding
- Flexibility with estimated tax payments
- Broader investment choices
- Personalized withdrawal strategies
When your funds are in an IRA, your advisor can help coordinate distributions in a tax-efficient and strategic way.
Avoiding the Most Common, and Most Costly, Rollover Mistake
Never have your 401(k) rollover check made out to you personally.
Here’s why:
- The IRS requires a mandatory 20% withholding
- You receive only 80% of your balance
- You must replace the withheld 20% out of pocket when depositing the rollover
- If you don’t, the withheld amount becomes taxable income, and if you’re under 59½, you may also face a 10% penalty
This creates a completely avoidable tax mess.
What to do instead
- Open your IRA first.
You’ll need the account number before requesting the rollover.
- Have the check made payable to your custodian
Example:
“Charles Schwab for the benefit of [Your Name], IRA #123456.”
- Have the provider send the check directly to the custodian
Not to your home.
If they insist on sending it to you, don’t panic. You have 60 days to forward it properly. But the best path is always a direct trustee-to-trustee transfer.
Understanding Your Contributions: Pre-Tax, Roth, and After-Tax
Your 401(k) may actually be a combination of several types of money, and each type must be rolled into the appropriate account.
Here’s the correct breakdown:
- Pre-tax contributions → Traditional IRA
- Roth contributions → Roth IRA
- After-tax contributions → Roth IRA
- After-tax earnings → Traditional IRA
This is often where mistakes happen...not with contributions, but with the earnings on after-tax money. Many plan providers won’t automatically separate these for you. You have to ask, or you may accidentally send tax-free money into a taxable account. This is an area where good planning can save you thousands over your lifetime.
Changing Jobs: Should You Consolidate or Keep Old 401(k)s?
When you switch employers, you have two primary options:
- Roll into your new employer’s 401(k)
This can simplify your life—if the new plan is strong. Before consolidating, review:
- Quality of investment options
- Fees
- Plan provider
- Whether you expect to use strategies like the backdoor Roth (having pre-tax money in an IRA complicates this)
- Roll to an IRA
This gives you the highest level of control:
- Broader investment choices
- Custom allocations
- Visibility in one place
- No employer-related restrictions
Exception:
If you’re a high-income earner using the backdoor Roth strategy, rolling to an IRA may trigger the pro-rata rule and unexpectedly increase your tax bill.
What about keeping an old 401(k)?
Sometimes it makes sense, especially if:
- The plan has excellent, low-cost investment options
- You want access to the age-55 withdrawal rule
- Your new employer requires a waiting period to join their plan
But managing multiple old 401(k)s can get complicated quickly. Consolidation is often easier and more effective.
Real-Life Q&A: What Other Investors Are Asking
Here are a few real scenarios we often see:
“I’m 55 and starting a new job. Should I roll over my old 401(k)?”
If you have stable income and don’t need penalty-free access via the Rule of 55, compare the new employer plan to an IRA. Choose whichever offers better options and lower fees.
“I have four old 401(k)s. Can I roll them into one older plan I like?”
Unfortunately, most former employers don't allow roll-ins.
Consolidate either into your current plan or an IRA, depending on whether you need to keep IRA balances low for tax strategies like the backdoor Roth.
“My 401(k) has pre-tax, Roth, and after-tax money. Can it all go into one IRA?”
No. Each type must go to the right place, or you risk turning tax-free Roth money into taxable distributions. Get professional guidance with this one
