Thinking about changing jobs or leaving your current employer? You’re not alone. Whether it’s for a better opportunity or a fresh start, one of the biggest financial questions you might have is: Can I keep my 401(k) if I leave my job? The good news is yes — your 401(k) doesn’t vanish when you walk out the door. But what happens next depends on a few key decisions you’ll need to make.
In this article, we’ll break down your options, explain the pros and cons of each, and help you make the best choice for your retirement savings.
What Happens to Your 401(k) When You Leave a Job?
When you leave a job, your 401(k) account stays intact, but it no longer receives contributions from your former employer. You still own your account and the money in it, but the plan is managed by your former employer’s plan administrator.
Key points to remember:
- You don’t lose your 401(k) just because you leave a job.
- Your contributions and vested employer contributions are yours to keep.
- Access to the account may change, depending on the plan’s rules.
Understanding Vesting: How Much of the 401(k) Is Really Yours?
Before you make any moves, it’s important to understand vesting. Vesting refers to how much of your employer’s contributions you’re entitled to keep when you leave.
Here’s how vesting works:
- Your contributions are always 100% vested.
- Employer contributions may vest over time (e.g., 20% per year over five years).
- If you leave before you’re fully vested, you might lose a portion of the employer match.
Check your plan’s vesting schedule before making any assumptions about how much you get to take with you.
Your 401(k) Options After Leaving a Job
Once you leave your job, you typically have four main options for your 401(k):
1. Leave it with your former employer
- Pros:
- No immediate action required
- Funds continue to grow tax-deferred
- Cons:
- Limited investment options
- Harder to manage multiple accounts
This option may be fine if the plan has good investment choices and low fees.
2. Roll it over to a new employer’s 401(k)
- Pros:
- Consolidates your retirement savings
- Maintains tax-deferred status
- Cons:
- Not all employers accept rollovers
- Limited by new plan’s investment options
Check with your new employer to see if their plan allows rollovers and how to initiate the process.
3. Roll it over into an IRA
- Pros:
- More investment choices
- Potentially lower fees
- Continued tax-deferred growth
- Cons:
- More responsibility for management
- Watch out for rollover mistakes that trigger taxes
Many prefer this option for the flexibility and control it offers.
4. Cash out your 401(k)
- Pros:
- Immediate access to funds
- Cons:
- Subject to income taxes
- 10% early withdrawal penalty if under age 59½
- Loss of future retirement savings
This is usually the worst option unless you have an emergency and no other resources.
When Should You Make a Decision?
While there’s no rush to make an immediate decision, especially if your account has a decent balance, it’s best not to let your old 401(k) sit and gather dust.
Consider making a move if:
- The old plan has high fees
- You want to consolidate multiple retirement accounts
- You’re changing jobs again and want a clean financial slate
Things to Watch Out For
Before deciding what to do with your 401(k), keep these tips in mind:
- Avoid taking a lump-sum distribution unless it’s absolutely necessary.
- Compare fees and investment options between your old and new plans or IRAs.
- Make sure any rollover is direct, to avoid unnecessary taxes or penalties.
FAQs About 401(k)s and Leaving a Job
Can my old employer take back my 401(k)?
No. Your own contributions and any vested employer contributions are yours. Unvested amounts may be forfeited if you leave early.
Can I contribute to my old 401(k) after I leave?
No. Once you leave the company, you can no longer contribute to that 401(k), but your money can stay invested.
How long do I have to decide?
There’s no hard deadline, but some plans may eventually charge inactivity fees or require you to roll over the funds if your balance is below a certain amount (usually under $5,000).
Final Thoughts: Keep Your Retirement on Track
Leaving a job is a big life change, and it’s the perfect time to make sure your retirement savings are still working for you. Whether you leave your 401(k) where it is, roll it over, or open an IRA, the key is to stay proactive.
Don’t forget: Every decision you make today can have a big impact on your financial future.
