What is a rollover IRA?
A rollover IRA is an individual retirement account created by transferring money from a 401(k) or other type of retirement account. A major benefit of a rollover IRA is that it keeps your retirement dollars safe from taxes when the process is done correctly.
Is a rollover IRA a good choice for my old 401(k)?
The answer here is often yes, but it's always good to review your possible options here. If you’re leaving a job, you have three basic choices — none of which allows you to continue contributing to the old 401(k), but all of which ensure that the money you’ve already contributed remains yours.
Leave it be. If your ex-employer lets you, you can leave the plan right where it is. This isn’t ideal, for a couple of reasons: You’ll no longer have an HR team at your disposal to help you with plan questions, and you may be charged higher 401(k) fees as an ex-employee.
Roll it over. This is the best choice for many people: You can roll your money into either your current employer’s retirement plan or into an IRA, and in many cases, the IRA is the destination of choice. There, you’ll have a wide variety of investment options and low fees, particularly compared with a 401(k), which can have tightly curated investment options and high administrative fees.
Cash out. This is almost certainly your worst option. Not only does cashing out sabotage your retirement — you’ll lose the power of compound interest, especially if you’re early in your career — but it comes with some brutal penalties and taxes levied by the IRS. You’ll pay a 10% early withdrawal fee, plus ordinary income taxes on the amount distributed. That means you might hand over up to 40% of that money right off the top.
How do you open a rollover IRA?
If you have an existing IRA, there's no need to start a new account: You can just roll your balance into the one you have. If you don’t, you’ll need to make two decisions up front: which type of IRA you want and where to open that account.
Choosing an account type
Traditional IRAs and Roth IRAs are by far the most popular types of individual retirement accounts. The main difference between them is their tax treatment:
Traditional IRAs can net you a tax deduction on contributions in the year they are made, but withdrawals in retirement are taxed. If you choose to roll over a 401(k) into this account, you will not pay any taxes on the rolled-over amount until retirement.
Roth IRAs don’t include an immediate tax deduction, so rolling to a Roth means you’ll have to pay taxes on the rolled amount. (The exception is if you’re rolling over a Roth 401(k), a type of 401(k) that mimics the tax treatment of a Roth IRA.) The upside of Roths is that withdrawals in retirement are tax-free after age 59½.
If you wish to keep things simple and preserve the tax treatment your 401(k) offered, a traditional IRA is an easy choice. That said, rolling to a Roth IRA may be a good option if you wish to minimize your tax bill in retirement. The caveat here is that you will likely face a decently sized tax bill today if you go with a Roth — again, unless your old account was a Roth 401(k). And if you need to use cash from the rollover to foot the tax bill today, this option is likely a bad choice, as you'll open yourself up to even more tax complications. Stick with a traditional IRA when that's the case.
Choosing a provider
Note that your choice of IRA provider is not the biggest driver of your portfolio’s growth. It is the investments you place within the IRA that determine most of that. However, selecting a provider is critical for keeping fees low and gaining access to the right investments and resources you need to manage your savings.
When deciding where to open a rollover IRA, the choice often boils down to two options: an online broker or a robo-advisor.
An online broker may be a good fit for you if you want to manage your investments yourself. Look for a provider that charges no account fees, offers a wide selection of low-cost investments and has a reputation for good customer service.
A robo-advisor may make sense if you want account management — choosing low-cost funds and rebalancing your portfolio over time according to your personal preferences and investment horizon — for a fraction of the cost of a human financial advisor. If you’re unsure how this works, check out our explainer on what is a robo-advisor to see if it’s the right choice for you.
In either case, you can review NerdWallet’s analysis of the best IRAs of 2019, which highlights top providers of both types. Or you can browse the providers below, each of which were highlighted in that report: Merrill Edge is a DIY brokerage that won in our category for best retirement tools, and Betterment, a robo-advisor, claimed top honors in our category for the best provider for hands-off investors.
How to do your rollover the right way
When you know what type of account you want and where you want to open it, it's time to start the rollover process.
Virtually IRA providers will offer ample support to help you do this — many have “rollover specialists” on staff — but the basics are simple: You’ll contact your former employer’s plan administrator, complete a few forms, and ask it to send a check for your account balance to your new account provider. (The new account provider should give you pretty explicit instructions for how the check should be made out, what sort of information should be included — like your new IRA account number — and where it should be sent.) Some providers allow you to wire the funds instead.
The key to all of the above is the phrase “direct rollover”; in other words, the money never touches your hands. You can also opt for an indirect rollover, which essentially means you’re withdrawing the money and moving it to the IRA provider yourself, a process that needs to be completed within 60 days. But this process can expose you to all sorts of further tax complexities, which is why we recommend a direct rollover in virtually all cases.
How to choose your investments
Once the money lands in your new IRA account, you can get down to the fun part: selecting your investments.
If this is your first IRA, you’ll probably be surprised at the vast number of investments on your doorstep, especially compared with the measly selection of 10 to 20 funds in your 401(k). But for most people, the best choice is to select a few low-cost index mutual funds or ETFs, based on the asset allocation — meaning the way you divide your money among stocks, bonds and cash — that makes sense for your age and risk tolerance.
If you’re not up for that, there are more hands-off options: If you were invested in a target-date fund in your 401(k), you can find a similar (and perhaps less expensive) fund through an IRA. And if you opened your new account at a robo-advisor, that company’s computer algorithms will take care of selecting and rebalancing your investments based on questions you answer about your timeline and stomach for risk.
That’s not to say you can turn a blind eye — we’d never recommend that — but there’s something to be said for turning over the bulk of the dirty work to someone (or, in the case of a robo-advisor, something) else.
