If you quit, odds are nothing will happen to your 401(k) unless you initiate it. If you’ve switched jobs and haven’t taken your old 401(k) with you, consider your four other options. There isn’t one right answer, but in most cases, taking an outright distribution is not advisable. The best option depends on your desire to consolidate, age, whether you hold company stock in the plan, what your new employer’s plan offers, what you’re paying now versus what you’d pay somewhere else, and other factors.
There are 5 options for your old 401(k) when you change jobs:
- 401(k) rollover into an IRA
- Convert to a Roth IRA
- Leave the money in the old plan
- Transfer to your new job
- Cash out your account
Most of the decision comes down to one question: should the money stay in an employer plan, or move to an IRA? Here are six key differences between 401(k) plans an IRAs. The rest of the article covers the unique pros and cons for each of the five post-termination 401(k) options.
401(k) vs IRA: 6 key account differences for 401(k) rollover decisions
Investment options and fees
A 401(k) limits you to the plan’s fund menu. An IRA doesn’t, so you can build virtually any allocation you want and control what you pay for it. Fees cut both ways: 401(k) participants usually pay the plan’s administration costs on top of fund expenses, and a limited menu can leave few alternatives to high-cost funds. But large plans may have institutional share classes and funds you can’t buy in an IRA, and some employers cover plan expenses entirely. A brokerage window in a plan can expand your investment options, but transaction costs and other rules may apply.
Creditor protection
401(k)s and other qualified plans get federal ERISA protection, which is the strongest available. IRA protection is generally weaker and varies by state. If asset protection is a real concern for you, speak to an attorney about your exposure and other options to potentially preserve the qualified plan status by opening a new rollover IRA account.
Getting to your money before 59½
IRAs permit penalty-free withdrawals for qualified education expenses, first-time homebuyers, and health insurance premiums paid while unemployed. 401(k)s don’t. But 401(k)s can permit penalty-free withdrawals beginning at age 55 if you separated from service in or after the year you turned 55. An IRA can allow penalty-free withdrawals at 55 or even earlier using the substantially equal periodic payment (SEPP) method. But payments must continue for at least five years or until you turn 59 1/2, whichever is longer. If you start a SEPP program at age 55, you’ll be able to stop at 60. Failure to follow the SEPP rules will trigger penalties and interest. Distributions from a pre-tax IRA are taxable as ordinary income.
Company stock and net unrealized appreciation
If you hold appreciated employer stock in the plan, look at net unrealized appreciation first. NUA treatment can convert most of the gain from ordinary income to income and long-term capital gains. Rolling the shares into an IRA forfeits it permanently, and so does rolling them into a new employer’s plan in most cases. It’s worth noting that unless you move the company stock to a brokerage account at some point, you will not benefit from NUA.
Contributing, consolidating, and RMDs
You can’t contribute to a plan you’ve left, but any taxpayer with earned income can contribute to an IRA, and Roth IRA contributions are permitted based on income. Consolidation is the practical argument for moving: fewer logins, easier to manage, no forgotten accounts. It also makes coordinated investment management possible, which generally isn’t available inside an old plan. Depending on the situation, a rollover may be necessary to access retirement planning services with an independent financial advisor. On the other side, if you work past RMD age and don’t own more than 5% of the business, an employer plan lets you defer RMDs until you fully retire. IRAs don’t allow that.
How often to rebalance a 401(k)
Future Roth moves and the pro-rata rule
A pre-tax IRA balance complicates backdoor Roth contributions, because the pro-rata rule looks at all of your traditional IRA money when you convert. Keeping the balance in a 401(k) instead of an IRA avoids that.
If you’ve already rolled money into an IRA and now have pre-tax and after-tax dollars mixed together, a reverse rollover can unwind it: move the pre-tax portion into your current employer’s plan, and the after-tax basis left behind can then be converted to a Roth IRA tax-free.
What should you do with your old 401(k) when you change jobs?
You will generally have five options when you quit or change jobs. While considering a 401(k) rollover, it’s also a good time to tackle some other job transition money moves.
401(k) rollover into an IRA
A direct rollover to an IRA gives you the most control over costs and investment options. That flexibility is worth a lot to some people and not much to others, so it’s not automatically the right move.
Quick comparison: Investment options — unlimited. Fees — often lower, controllable. Creditor protection — weaker than a plan. Access before 59½ — IRA exceptions and SEPP. Company stock — NUA forfeited. Contributions — permitted.
What’s specific to this option:
- Continue tax-deferred growth: with a direct rollover to an IRA, you won’t owe any taxes when rolling over your 401(k). To avoid any mistakes, make sure to have the rollover check made payable to the new financial institution where you have your IRA for your benefit. The easiest way is to work with a financial advisor: we help clients with all the paperwork!
- No limits on direct rollovers: as long as you do a custodian to custodian direct rollover (so you don’t take the funds personally) you can do multiple rollovers in a year if you change jobs frequently or just have a bunch of old 401(k)s. The once-per-12-months rule only applies to 60-day indirect rollovers between IRAs.
- If you have after-tax (non-Roth) contributions in the plan, a direct rollover lets you split them out: the after-tax dollars can go to a Roth IRA and the pre-tax portion to a traditional IRA. This matters if you’ve been doing mega backdoor Roth contributions.
- Evaluate costs at the new financial institution including advisory, custodial fees, and fund expenses on the new asset allocation
Convert your 401(k) into a Roth IRA
A Roth conversion always sounds like a good idea, until people realize they have to pay tax on the entire amount. If you’re a high-earner, it may not make sense to convert to a Roth as your tax bracket could be lower in retirement. A gap year between jobs, early retirement, or a year with low income, is usually when a conversion makes the most sense.
Quick comparison: Same as a traditional IRA on investment options, fees, creditor protection, early access, and company stock. The difference is when you pay the tax.
What’s specific to this option:
- After paying tax in the year of conversion, the account grows tax-deferred like an IRA or 401(k), but after reaching age 59½ and if at least 5 years has passed since your Roth IRA was opened, the money can be withdrawn tax-free
- Roth IRAs have no required minimum distributions during your lifetime
- Anyone can do a Roth conversion – there are no income limits
- You can convert all or part of your 401(k)
- The conversion is included in your taxable income for the year, which could put you in a higher tax bracket. A Roth conversion generally isn’t a good idea if you need to take money from the retirement account to pay the tax. Further, if you are in a much higher tax bracket now than you expect to be in later, this strategy may not be worthwhile.
- Bigger conversions can also raise Medicare IRMAA premiums two years later and increase the tax on other income
Should you leave your 401(k) at your old job?
Leaving your 401(k) behind isn’t usually the best long-term plan, though there are reasons to do it. If you want to leave it at your old job, and your vested balance is above the plan’s cash-out threshold, you probably can.
Quick comparison: Investment options — the plan menu, potential brokerage window. Fees — plan costs plus fund expenses continue. Creditor protection — strongest. Access before 59½ — rule of 55 may apply. Company stock — NUA preserved. Contributions/loans — not permitted.
What’s specific to this option:
- Nothing changes, you are familiar with the investment options, costs, plan services, etc.
- No action is required; you can decide what to do with the money later
- Maintain access to participant services offered to former employees, if any
- Can be harder to view/manage your accounts and understand where you stand financially; easier to forget about the account
- Multiple logins
- Small balances can get forced out of the plan without you doing anything
Where to save after maxing out a 401(k)
Transfer your 401(k) to your new job
Transferring your 401(k) to your new job is like a 401(k) to 401(k) rollover. Depending on the set up of your new plan, it’s probably a better option than leaving it behind, but the plan’s fees and fund lineup decide whether it beats an IRA. Check the plan documents of your new employer’s 401(k) to confirm the plan accepts incoming rollovers.
Quick comparison: Investment options — the new plan’s menu. Fees — depends on the plan. Creditor protection — strongest. Access before 59½ — rule of 55 may apply. Company stock — NUA usually forfeited. Contributions — permitted, you’re an active participant.
What’s specific to this option:
- Consolidate: this makes it easier to manage and invest consistently. You can’t forget about your old retirement plan.
- 401(k) loans: consider whether the plan offers 401(k) plan loans and whether you may need to avail yourself of this provision. Only employer plans can offer loans
- Keeping the balance out of a pre-tax IRA preserves clean backdoor Roth contributions, and a plan that accepts incoming rollovers may also accept a reverse rollover later
- Services: as a plan participant you may have access to services in the plan, such as investor tools and education. Keep in mind that as an active participant, you would likely have access to these resources regardless of whether you roll money from your old plan into the new one
- Final: you can’t roll the money back once you roll it in. Your assets will have to stay in the plan until you switch jobs or retire
- Consider plan administration fees and expenses, including cost-sharing with your employer (if any). Also consider the expense ratios and fees for the investments in the plan
Cash out your 401(k)
This is the option to avoid unless you’re out of alternatives. Cashing out means you’ll owe ordinary income tax on the full amount in the year you take it, plus a 10% early withdrawal penalty if you’re under 59½ and no exception applies. The plan is also required to withhold 20% for federal taxes on any distribution paid to you instead of rolled over directly.
This is the only option that takes the money out of the retirement system. Every advantage in the comparison above goes away. It may be reasonable for a very small balance where the administrative hassle outweighs the amount, or in a genuine emergency after other sources are exhausted
How long do you have to complete a 401(k) rollover?
With a direct rollover, there’s no deadline. The money moves custodian to custodian and you’re never in possession of it.
The 60-day clock only applies if the check is made payable to you. In that case you have 60 days from receipt to deposit the full amount into the new account, and the plan will have already withheld 20%. To complete a full rollover you have to replace that 20% out of pocket and wait for the refund at filing. Miss the 60 days and the whole distribution is taxable, plus the 10% penalty if you’re under 59½. Direct rollovers avoid all of this.
Can your old employer force you out of the plan?
Yes, if your balance is small. Plans are allowed to cash out terminated participants with vested balances up to $7,000. The $7,000 figure is a ceiling, not a requirement: plans can set any threshold below it or have no force-out provision at all.
If you’re forced out and don’t tell the plan what you want, balances between $1,000 and $7,000 are rolled into an IRA chosen by the plan sponsor, usually invested in cash. Balances under $1,000 can be sent to you as a check, which triggers tax and potentially the penalty. Some plans also participate in auto-portability networks that move small balances to your new employer’s plan automatically.
Above the plan’s threshold, you can’t be kicked out. Unless the 401(k) plan itself terminates, you can stay invested in the plan.
Frequently asked questions
Nothing automatic unless your account balance is small. The money stays invested, including any vested employer matching or vested profit-sharing contributions. Your own contributions and investment growth will always remain yours. You can then choose among five options for your old 401(k): leave it, roll it to your new employer’s plan, roll it to an IRA, convert it to a Roth IRA, or cash it out.
There’s no single answer. For example, a direct rollover to an IRA usually gives the widest investment selection and best opportunity for account consolidation. Staying in a plan can be better if you are doing backdoor Roth IRA contributions annually or have access to participant services as a former employee.
Not on a direct rollover to a traditional IRA or another employer plan. You’ll owe income tax if you convert pre-tax dollars to a Roth, take a distribution, or do a 60-day rollover (withholding required, refund possible).
It depends on your cost basis in the shares and how concentrated you already are in employer stock. With the NUA rules, you can consider rolling only the stock into a brokerage account. The rest can go into an IRA. You’ll pay ordinary income tax on your cost basis in the employer stock. The remaining spread will be eligible for long-term capital gains tax treatment when the shares are eventually sold. The difference between the original cost of the stock and the current market value of the shares at the time of distribution is the net unrealized appreciation. But if you are already trying to diversify, selling the shares in a retirement account won’t have any tax implications.
