Changing jobs is exciting, but it leaves behind a question many people put off: what happens to the money in your old 401(k)? Leaving it where it is is an option, but it is rarely the best one. Learning how to roll over a 401(k) lets you keep your savings growing tax-deferred, cut down on scattered accounts, and often get better investment choices and lower fees.
This guide walks you through every step of a 401(k) rollover, explains the difference between direct and indirect rollovers, and highlights the costly mistakes that trip up first-timers.
What Is a 401(k) Rollover?
A 401(k) rollover is the process of moving money from an employer-sponsored retirement plan into another qualified account. That is usually an individual retirement account (IRA) or your new employer’s 401(k). Done correctly, the move is not taxable and does not trigger early withdrawal penalties. Your savings simply change homes while keeping their tax-advantaged status.
The key words are “done correctly.” The IRS has strict rules about how and when the money moves. Breaking them can turn a routine transfer into a surprise tax bill.
Your Four Options for an Old 401(k)
Before you start, it helps to know every choice on the table:
- Leave it with your former employer. Many plans allow this if your balance is above $7,000. It takes no effort, but you keep limited investment options and may lose track of the account.
- Roll it into your new employer’s 401(k). This keeps everything in one place and may let you borrow against the balance later. Confirm first that the new plan accepts incoming rollovers.
- Roll it into an IRA. This is the most popular choice. IRAs usually offer the widest range of investments, including stocks, bonds, ETFs and index funds, often at lower cost.
- Cash it out. This is almost always the worst option. You owe income tax on the full amount and, if you are under 59½, usually a 10% early withdrawal penalty on top.
Direct vs. Indirect Rollover: Know the Difference
The way your money moves matters as much as where it goes.
Direct rollover (trustee-to-trustee). Your old plan sends the money straight to your new account. You never touch it, no taxes are withheld, and there is no deadline to worry about. This is the method most experts recommend.
Indirect rollover. Your old plan sends a check to you, and you have 60 days to deposit it into a new retirement account. The catch is that the plan must withhold 20% for federal taxes. To roll over the full balance, you have to replace that 20% from your own pocket. Any amount you don’t deposit is treated as a taxable distribution.
Here is how that looks in practice. Say your balance is $50,000. With an indirect rollover, you receive a check for $40,000. To avoid taxes, you must deposit the full $50,000 within 60 days, covering the missing $10,000 from savings. You get the withheld amount back as a refund when you file your taxes. If you can only deposit the $40,000, the other $10,000 becomes taxable income.
How to Roll Over a 401(k) in 6 Steps
Step 1: Decide Where the Money Will Go
Choose between an IRA and your new employer’s plan, then match the account type. Pre-tax 401(k) money goes into a traditional IRA with no tax due. Roth 401(k) money goes into a Roth IRA. Moving pre-tax money into a Roth IRA is a Roth conversion, and you will owe income tax on the converted amount that year. If you are weighing the Roth route, our guide on how to open a Roth IRA covers eligibility and setup.
Step 2: Open the Receiving Account
If you are rolling into an IRA, open one at a brokerage or robo-advisor before you contact your old plan. Many providers label it a “rollover IRA.” Write down the account number and the custodian’s mailing details, because your old plan will ask for them.
Step 3: Contact Your Old Plan Administrator
Call the plan administrator or log in to their website and request a direct rollover. Ask whether they transfer electronically or mail a check, what forms they need, and whether they charge a closing fee.
Step 4: Complete the Paperwork
Fill out the distribution form and select “direct rollover.” If the plan mails a check, it should be made payable to your new custodian “for the benefit of” you, not to you personally. Double-check every account number before you submit.
Step 5: Track the Transfer
Most rollovers take one to three weeks. If a check arrives at your home made out to the new institution, forward it right away. It still counts as a direct rollover, so no taxes are withheld.
Step 6: Invest the Money
This is the step people forget most. Rolled-over funds often land in a cash or money market position. Until you pick investments, your money is not growing. Choose a mix that matches your age, goals and comfort with risk.
Tax Rules You Need to Know
A few rules keep a rollover tax-free:
- Expect a Form 1099-R. Your old plan reports the distribution, and you report the rollover on your tax return. A direct rollover should show as non-taxable.
- Respect the 60-day rule. For indirect rollovers, missing the deadline makes the money taxable, plus the 10% penalty if you are under 59½.
- Watch outstanding 401(k) loans. Leaving a job can make a plan loan come due. An unpaid balance is treated as a distribution, though you generally have until your tax filing deadline to roll that amount over.
- Check for company stock. If you hold employer stock that has grown a lot, ask a tax professional about net unrealized appreciation rules before rolling it into an IRA.

When You Might Not Want to Roll Over
A rollover is not right for everyone. If you leave your job in or after the year you turn 55, the “rule of 55” may let you take penalty-free withdrawals from that employer’s plan, a benefit you lose by moving the money to an IRA. Some 401(k) plans also offer low-cost institutional funds that are hard to beat. And employer plans generally carry strong federal protection from creditors.
Final Thoughts
Knowing how to roll over a 401(k) protects years of hard-earned savings. Choose a direct rollover, match the account type, and invest the money once it lands. If your situation involves company stock, loans or a Roth conversion, a short call with a tax professional is money well spent.
