A 401(k) rollover is the process of moving the funds from an existing employer-sponsored 401(k) to a new account. Generally, a 401(k) rollover happens when youâre switching jobs, retiring, or looking for more flexibility and choice when it comes to your investment options.
Whether youâre rolling over an old 401(k) account to a new employerâs 401(k) or to an individual retirement account (IRA), itâs important to do it right. In many cases, you have to stick to a specific set of timelines and rules or you could end up paying unnecessary taxes and penalties. This step-by-step guide explains how to complete a 401(k) rollover successfully.
Trying to decide what to do with an old 401(k)? Read about the pros and cons of 401(k) rollover options.
Before you do anything, make sure you know the specifics of your current plan. How much money is in your account? Has your employer matched a portion of your contributions? If so, how much of those matched funds are vested? Some companies require employment for a certain number of months or years before you gain full ownership of (or âbecome fully vested inâ) the money theyâve contributed.
Next: Did your contributions go into a traditional or Roth 401(k)? If youâre not sure, ask. And if youâre not clear on the differences between a Roth and a traditional plan, read this refresher. Note that employer contributions are always treated as a traditional plan, so if your personal contributions are in a Roth, youâll likely have two accounts that need to be rolled over. This distinction will be important when it comes time to complete the rollover paperwork.
Unless you absolutely, positively need to cash out now, itâs best to roll your 401(k) into another tax-advantaged account, such as your new employerâs 401(k) or an IRA. That way, youâre most likely to avoid paying taxes and early withdrawal penaltiesâsomething youâll definitely face if you choose to cash out your old 401(k) instead.
If youâve switched jobs, itâs usually easiest to roll your old 401(k) directly into your new employerâs plan, as long as they allow transfers (which most do).
You may decide to roll your 401(k) into an IRA through a bank or other financial institution if:
Most IRAs are managed by banks, brokers, insurance, or mutual fund companies. If you go the IRA route, look for a firm that:
Not all IRA providers are created equal, so make sure you understand the fee structure before opening an account. Do your research and ask plenty of questions. Itâs your money, so it pays to shop around.
Youâll need to get in touch with your old employer and, potentially, the company that manages your existing 401(k) account to begin the rollover process. Youâll have to fill out some paperwork and provide information such as your Social Security number, old 401(k) account number, and the account number and institution for your new rollover 401(k) or IRA.
If youâre doing a rollover to your new employerâs 401(k), youâll probably also need to contact the human resources department or plan administrator at your new job to request any additional paperwork and confirm that transfers from outside accounts are allowed. Once youâve completed all the necessary paperwork for the direct rollover into your new 401(k), the financial companies involved in the rollover will often take care of the rest. They may reach out to you if questions come up during the transition from the old account to the new one.
If youâre rolling over your money into an IRA instead of your new employerâs 401(k) plan, itâs possible youâll be mailed a check written to your new IRA institution (not made out to youâsee sidebar), which youâll need to deposit with them. Yes, even in the age of lightning-fast digital money transfer, some transactions must be completed the old-fashioned way. If youâre unaccustomed to having your money out of the market for a while, the process might be unsettling. Itâs important that the check is not written to you personally nor deposited into your personal bank account.
Here are some additional caveats to keep in mind:
Did you know that, according to IRS rules, if your old employer sends a check or electronic transfer to you in your name, itâs required to withhold 20% for tax purposes? Even if you plan to roll the funds directly into a new plan within 60 days (which, by their rules, youâre allowed to do), your employer will send 80% of the proceeds to you and 20% to the IRS.
Granted, if you roll the funds properlyâincluding the amount withheldâyouâll file a form along with your taxes next year and, all else equal, youâll get the money back. But still, itâs a hassle, and if you donât have extra cash lying around to cover the amount withheld, you might have no choice but to take the distribution and the tax hit. How can you avoid this?
First, try to get a direct transfer from the old plan to the new one. That way, the funds will never touch your hands, and 100% (minus any transfer fees assessed by your old plan, of course) will roll over to the new account.
If they want to distribute the funds to you, make sure the proceeds are made out to your new institution (and preferably your account number). You might be asked by your old employer to check a box stating that because itâs a direct rollover, youâre not subject to the 20% withholding.
Once youâve confirmed the money has arrived in your rollover 401(k) or IRA, itâs time to decide where to invest. If youâre moving money over to your new employerâs 401(k), your options may be limited, but that might also make it easier for you to choose. Many 401(k)s offer choices for investors who prefer to be more hands-off, depending on your tolerance for risk and when you plan to retire.
If you chose an IRA, youâll likely have access to additional options that may not have been available in your previous employerâs 401(k). This can be advantageous if you prefer to be more hands-on with your investing decisions.
No matter which 401(k) rollover option you choose, you need to be aware of the rules and potential tax implications of your decision. If youâve worked hard and saved diligently, it would be a bummer to face a tax penalty because of a mix-up.
Follow the steps carefully and stick to the required timelines to avoid any surprises, and make sure you stay on track to meet your retirement goals.
