Nothing dramatic happens. That’s the first thing worth saying, because people often assume there’s a deadline they’ve missed.
When you leave an employer, the money you contributed is yours, and so is any employer match that has vested. The account stays where it is. The investments keep doing whatever they were doing. Nobody closes it, and nobody is going to call you about it.
That’s exactly why so many of these accounts sit untouched for a decade. There’s no forcing event. But “nothing happens” isn’t the same as “nothing should happen,” and there are a few mechanics to understand before you decide to leave it alone on purpose rather than by accident.
The small-balance exception
There is one situation where the plan can act without you.
If your vested balance is small, the plan is permitted to push you out. Under current rules, a balance under $1,000 can be cashed out and mailed to you as a check, which creates an immediate tax bill and, if you’re under 59½, potentially a penalty. A balance between $1,000 and $7,000 can be automatically rolled into an IRA chosen by the plan, often into a conservative default investment with its own fee structure.
If you’ve left a job in the last few years with a modest balance and never heard anything, confirm where that money actually is. Checks get mailed to old addresses.
Your four options
1. Leave it in the old plan
Worth considering when the plan has low institutional-grade fees and a solid fund lineup. Large employer plans often negotiate pricing an individual simply cannot get on their own, and that advantage is real.
The drawbacks are practical. You’re limited to that plan’s investment menu. A former employer controls the plan and can change recordkeepers, fund options, or fee structures without consulting you. And accounts scattered across three or four former employers are easy to lose track of, which matters more than it sounds when beneficiaries have to find them someday.
2. Roll it into your new employer’s plan
Useful if you’re still working and the new plan is strong. Everything sits in one place, and if you’re still contributing, you’re watching one account instead of several.
Check the new plan’s fees and fund menu first. Consolidation is only an improvement if you’re consolidating into something better. Not every plan accepts incoming rollovers, either.
3. Roll it into an IRA
This opens up the widest range of investment choices and puts you in direct control. For many people approaching retirement, that flexibility is the main appeal.
What you may give up is less obvious:
- Creditor protection. Assets in an employer plan covered by ERISA generally receive strong federal protection. IRAs rely on state law instead. Texas is relatively favorable here, but the analysis is different, and if you’re in a profession with liability exposure, have a specific conversation with your attorney.
- The age-55 exception. If you separate from service in or after the year you turn 55, you can generally take distributions from that employer’s plan without the 10% early withdrawal penalty. Roll the money to an IRA and that exception is gone; IRAs use 59½. For someone retiring at 56 who may need access, this is a costly detail to discover afterward.
- Company stock. If your 401(k) holds appreciated employer stock, a strategy called net unrealized appreciation may allow favorable capital gains treatment on the growth. A standard rollover forfeits it. This one is narrow but can be worth a lot where it applies.
4. Convert some or all to a Roth
You pay income tax now on what you convert, in exchange for tax-free growth and no required distributions later. This can make real sense in an unusually low-income year, commonly the stretch after you stop working but before Social Security and required distributions begin.
It’s not free, and the tax bill is only part of it. Converting raises your income for the year, which can affect how much of your Social Security is taxable and can increase your Medicare premiums two years later through IRMAA. If you hold multiple IRAs containing both pre-tax and after-tax dollars, the pro-rata rule may make the taxable portion of a conversion larger than expected.
A comparison to do on paper
Before moving anything, get these five answers written down:
- What am I paying in total annual fees today, in dollars, not percentages?
- What would I pay in the new arrangement, all in, including any rider or advisory fees?
- What am I giving up: liquidity, creditor protection, a plan-specific exception, a company stock provision?
- If I change my mind in three years, what does it cost me to get out?
- Who gets paid what if I do this, and who gets paid nothing if I don’t?
That last question is the one most people never ask, and it’s the one that explains the most.
A disclosure, since it belongs here
I’m a licensed insurance agent. If you roll a 401(k) into an IRA and use it to purchase an annuity through me, I receive a commission from the issuing insurance carrier. Leaving your money exactly where it is pays me nothing.
That’s a real conflict of interest, and you’re entitled to know about it before we discuss your accounts rather than after. If we work together, you’ll get it in writing, and any comparison I give you will include the option of doing nothing at all, because for a meaningful number of people, that is the right answer.
