Rolling over a 401(k) to an IRA takes a few steps: open an IRA at the brokerage of your choice, contact your old plan administrator to request a distribution, and have the funds sent to your new account. The entire process typically takes one to three weeks, and when done correctly, you won’t owe any taxes or penalties. The key decision is choosing the right type of rollover and the right type of IRA, because getting either one wrong can cost you money.
Direct Rollover vs. Indirect Rollover
There are two ways to move your 401(k) money into an IRA, and one is significantly safer than the other.
A direct rollover (sometimes called a trustee-to-trustee transfer) sends your money straight from your 401(k) plan to your new IRA custodian. You never touch the funds. No taxes are withheld, and there’s no deadline pressure. This is the method most people should use.
An indirect rollover means your old plan cuts a check to you personally. When this happens, the plan is required to withhold 20% of the distribution for federal taxes. You then have 60 days from the date you receive the money to deposit the full original amount into your IRA. If you want to roll over the complete balance, you’ll need to come up with that withheld 20% out of pocket and deposit it alongside the check. You get the withheld amount back when you file your tax return, but only if you completed the rollover on time.
If you miss the 60-day window, the entire distribution becomes taxable income for that year. On top of that, if you’re under age 59½, you’ll face a 10% early withdrawal penalty on the taxable portion. The IRS does offer waivers for circumstances beyond your control, and there’s a self-certification process if you qualify, but it’s far simpler to avoid the risk entirely by choosing a direct rollover.
Step-by-Step Process
The mechanics are straightforward once you know the order of operations.
1. Open your IRA. If you don’t already have one, set up an IRA at the brokerage or financial institution where you want to invest. Most major brokerages let you open an account online in about 15 minutes. Make sure you’re opening the right type (traditional or Roth, covered below).
2. Get your new account details. Your IRA custodian will provide an account number and, if needed, a letter of acceptance or specific mailing instructions for incoming rollovers. Some brokerages have dedicated rollover teams that will handle most of the coordination for you.
3. Contact your old 401(k) plan administrator. Call the number on your 401(k) statement or log into your plan’s website. Request a direct rollover to your new IRA. You’ll typically need to provide your new IRA account number, the receiving custodian’s name, and their mailing address. Some plans have a specific rollover or distribution form to fill out.
4. Specify a direct rollover. Make sure you explicitly request a direct rollover so the check is made payable to your new custodian (for example, “Fidelity Investments FBO [Your Name]”) rather than to you personally. This avoids the 20% withholding.
5. Choose what to do with your investments. Your 401(k) holdings will almost always be liquidated (sold) before the transfer, since your new IRA won’t carry the same fund lineup. The money arrives as cash, and you’ll need to reinvest it once it lands in your IRA. Don’t let the cash sit uninvested if your goal is long-term growth.
The full process usually takes one to three weeks depending on how quickly your old plan processes distributions. Some plans are faster than others, and a few still mail physical checks to the new custodian rather than wiring the funds.
Traditional IRA vs. Roth IRA Rollover
Where you roll your money matters for taxes. A traditional 401(k) holds pre-tax dollars, meaning you never paid income tax on that money. If you roll it into a traditional IRA, there’s no tax bill. The money stays tax-deferred and you’ll pay income tax when you withdraw it in retirement, just as you would have from the 401(k).
If you roll a traditional 401(k) into a Roth IRA, that’s a Roth conversion. You’ll owe income tax on the entire converted amount in the year you do it, because Roth accounts hold after-tax money. The upside is that future growth and qualified withdrawals from the Roth IRA are completely tax-free. Converting portions over several years rather than all at once can help you manage the tax hit by keeping yourself in a lower bracket each year.
If your 401(k) has a designated Roth component (meaning you made after-tax Roth contributions through your employer), those funds can roll into a Roth IRA with no additional tax owed.
When Rolling Over Could Cost You
A rollover makes sense for most people, but there’s one scenario where it can backfire. If you left your job at age 55 or older, the Rule of 55 allows you to take penalty-free withdrawals from that employer’s 401(k) even though you haven’t reached age 59½. This rule only applies to a former employer’s workplace plan. The moment you roll that money into an IRA, you lose access to the Rule of 55, and any withdrawals before 59½ could trigger the 10% early withdrawal penalty.
If you’re between 55 and 59½ and think you might need to tap your retirement savings, consider leaving enough in the 401(k) to cover those potential withdrawals and rolling over only the rest.
What Happens to an Old 401(k) You Don’t Roll Over
You’re not required to roll over your 401(k) when you leave a job. The money can stay in your former employer’s plan as long as the balance is above the plan’s minimum threshold (often $5,000). But there are practical reasons to move it. Old 401(k) plans tend to have a limited menu of investment options and may charge higher administrative fees than a self-directed IRA. Consolidating old accounts into a single IRA also makes it easier to manage your asset allocation and track your retirement savings in one place.
If your balance is under $5,000 and you don’t act, some plans will automatically distribute the funds to you or roll them into a default IRA, which may not be invested the way you’d choose. Staying proactive avoids surprises.
Costs and Fees to Watch
Most brokerages charge nothing to open an IRA or receive a rollover. Your old 401(k) plan, however, may charge a distribution or account-closing fee, typically in the range of $50 to $100. Check your plan documents or call the administrator to find out. Some brokerages will reimburse this fee if you ask, especially for larger balances.
Once your money is in the IRA, pay attention to the expense ratios on the funds you choose. One of the biggest advantages of an IRA over a 401(k) is access to a wider range of low-cost index funds and ETFs. Moving from a 401(k) with fund expenses of 0.50% or more into an IRA with options below 0.10% can save you thousands over a long retirement horizon.
