What Should You Do With an Old 401(k) After Leaving a Job?
One of the most common financial questions people ask is:
“I just left my job, what should I do with my 401(k)?”
Whether you changed jobs, were laid off, or decided to retire, your old 401(k) doesn’t disappear. But what you choose to do with it next can have a significant impact on your taxes, investments, and long-term financial flexibility.
Let’s walk through the four main options you typically have when you leave an employer and how to think about which one may be right for you.
The 4 Options for Your Old 401(k)
When you leave a job, you generally have four choices:
Leave the money in your old 401(k)
Roll it into your new employer’s 401(k)
Roll it into an IRA
Cash it out
Let’s break each of these down.
Option 1: Leave It in Your Old 401(k)
In many cases, you can simply leave the money where it is. Most plans require your balance to be above a certain amount, typically around $5,000.
Pros
No changes required
No taxes triggered
You may have strong investment options in the plan
Cons
You can no longer contribute to that account
You have limited control over the plan
Many people eventually forget about old accounts
For some people, leaving the money where it is works as a short-term solution, but it may not be the most flexible option long term.
Option 2: Roll It Into Your New Employer’s 401(k)
Another option is rolling your old 401(k) into your new employer’s plan.
Pros
Keeps all retirement savings in one place
Allows continued tax-deferred growth
Simple and easy to manage
Cons
Not all 401(k) plans are created equal
Some plans have high fees
Investment choices may be limited
This option largely depends on how good your new employer’s plan is.
Option 3: Roll It Into an IRA
Rolling your 401(k) into an Individual Retirement Account (IRA) is one of the most popular choices.
Why many people choose this option:
More investment choices
Greater control over your portfolio
More flexibility with long-term tax planning
If your 401(k) includes Roth contributions, those funds can be rolled into a Roth IRA, allowing them to continue growing tax-free.
This option is often appealing for people who want more personalization in their investment strategy.
Option 4: Cash It Out
You can always choose to withdraw the money, but this option typically comes with significant downsides.
What happens if you cash it out?
The entire amount becomes taxable income
You may owe a 10% early withdrawal penalty
You permanently remove that money from your retirement savings
What may feel like a short-term financial solution can often turn into long-term regret.
How Do You Decide What’s Best?
The right decision depends on several factors, including:
Your age
Your current tax situation
The quality of your new employer’s benefits
Your long-term financial goals
Like many things in financial planning, there isn’t a one-size-fits-all answer. But there is usually a strategy that makes the most sense for your situation.
The Bottom Line
If you’ve recently left a job and aren’t sure what to do with your 401(k), don’t rush the decision.
Taking the time to make a thoughtful choice now can have a major impact on your long-term financial future.
