What to Do With an Old 401(k) From a Past Job
I have two 401(k)s sitting at former employers, so I have wrestled with this. Here are your four options for an old 401(k), and the one that quietly costs you the most.
When you leave a job, your 401(k) does not come with you automatically, and it does not disappear either. It just sits there, still invested, still yours, quietly waiting for you to decide what to do with it. And a lot of us never quite get around to deciding.
I know, because I am one of them. I have two 401(k)s parked at former employers right now. They are not lost, but they are scattered, and figuring out the smartest move for them is exactly the kind of thing I ended up walking through with my financial advisor. So this is not theory for me. Here are your four options, and the honest case for and against each.
Your four options
| Option | What it means | Worth it when |
|---|---|---|
| Leave it | Keep it in the old employer’s plan | The plan has great, low-cost funds |
| Roll to new 401(k) | Move it into your current job’s plan | You want everything in one workplace account |
| Roll to an IRA | Move it into an IRA you control | You want the most choice and often lower fees |
| Cash out | Take the money now | Almost never |
Leave it where it is
Doing nothing is a legitimate choice, at least for a while. The money stays invested and keeps growing. The downside is drift: old accounts get forgotten, you lose track of the investments, and you may be paying higher fees than you realize. Fine short-term, rarely ideal forever.
Roll it into your new 401(k)
If your current job has a solid plan, consolidating your old balance into it keeps things simple and everything in one place. Just check that the new plan’s investment options and fees are actually good before you move money into them.
Roll it into an IRA
This is the option that gives you the most control. An IRA opens up a huge menu of low-cost investments instead of a limited plan lineup, and it puts the account fully in your hands. For a lot of people, this is the move, which is exactly why I looked hard at it for my own orphaned accounts.
Cash it out (please do not)
This is the one that quietly wrecks people. If you are under 59½, cashing out usually means income tax plus a 10% penalty, and you throw away decades of future tax-advantaged growth. A balance can lose a third or more of its value the moment it hits your checking account.
An old 401(k) is not free money to spend. Cashing it out early is the single most expensive “mistake that felt like a solution” in retirement saving.
The one rule if you do roll it over
If you decide to move the money, always ask for a direct rollover, where the funds go straight from the old plan to the new account without ever touching your bank. That avoids a mandatory 20% withholding and a 60-day scramble that can accidentally turn your rollover into a taxable withdrawal. Direct rollover, every time.

Frequently asked questions
What happens to my 401(k) when I leave a job?
Nothing automatic happens right away. The money stays invested in your old employer's plan and remains yours. You generally have four choices: leave it where it is, roll it into your new employer's 401(k), roll it into an IRA, or cash it out. Doing nothing is a valid short-term option, but many people eventually roll it over for more control and lower fees.
Should I roll over my old 401(k) to an IRA?
Often, yes. Rolling an old 401(k) into an IRA usually gives you far more investment choices and can mean lower fees, plus everything sits in one place you control. The main reasons to keep it in a 401(k) instead are strong low-cost funds in the plan or certain creditor protections. It is a good question for a financial advisor.
Can I cash out my old 401(k)?
You can, but it is usually the worst option. If you are under 59½, cashing out typically means income tax plus a 10% early-withdrawal penalty, and you lose all the future tax-advantaged growth. A large balance can shrink by a third or more instantly. Rolling it over instead keeps the money working and tax-advantaged.
How do I roll over a 401(k) without paying taxes?
Use a direct rollover, where the money moves straight from your old plan to the new 401(k) or IRA without passing through your hands. That avoids the mandatory 20% withholding and the 60-day deadline that come with an indirect rollover. Done as a direct rollover into a like account, it is not a taxable event.
