You can move old 401(k) balances into your current plan or into an IRA

When you leave a job, your 401(k) stays with that employer's plan unless you move it. You have three main routes: roll the balance into your new employer's 401(k) if they allow it, roll it into a traditional IRA you open yourself, or leave it where it is. Most people combine accounts into one place to simplify tracking, reduce fees, and keep all their retirement money under one set of rules.

The mechanics depend on which accounts you're combining and where they're going. A rollover from one 401(k) to another 401(k) works differently than a rollover to an IRA, and both differ from combining IRAs. The timeline is usually quick—two to four weeks for the money to land—but the paperwork and tax consequences matter.

Key Takeaways

  • A direct rollover moves money straight from one plan to another without you touching it, which avoids taxes and penalties.
  • Your new employer's 401(k) may not accept rollovers, so check their plan rules before you leave your old job.
  • Rolling a 401(k) into a traditional IRA gives you more investment choices and lower fees, but you lose access to certain creditor protections and employer loan options.
  • If you receive a check instead of a direct rollover, you have 60 days to deposit it into another retirement account or face taxes and a 10% penalty on the full amount.
  • Combining multiple IRAs into one IRA is simpler than moving 401(k)s and can usually be done online or by phone with your bank or brokerage.

Rolling a 401(k) into your new employer's plan

If your new job offers a 401(k), ask the plan administrator whether they accept rollovers from previous employers. Not all plans do. If they do, request a direct rollover from your old plan to the new one. This means the money moves straight from the old employer's custodian to the new one without passing through your hands.

You'll need to provide your new plan administrator with your old plan's contact information. They handle the paperwork with the old custodian. The old plan will send the balance directly to the new plan's custodian, usually within two to four weeks. No tax withholding occurs, and you avoid the 60-day deposit deadline that applies to checks sent to you.

One limitation: your new plan's investment menu becomes your only choice. If the new plan offers fewer funds or higher expense ratios than you'd prefer, you're locked into those options. Also, some plans don't allow loans against rolled-over balances, or they impose stricter withdrawal rules on rolled money than on contributions you make going forward.

Rolling a 401(k) into a traditional IRA

A rollover to a traditional IRA gives you more control over investments and typically lower fees than a 401(k). You can hold individual stocks, bonds, mutual funds, and ETFs in an IRA, whereas 401(k)s limit you to the plan's menu. IRA custodians—banks, brokerages, and investment firms—usually charge lower annual fees than employer plans.

Open a traditional IRA with a custodian of your choice, then request a direct rollover from your old 401(k). Provide the IRA custodian's details to your old plan administrator. The money moves directly, no tax withholding, no 60-day clock. The process takes two to four weeks.

The trade-off: IRAs offer less legal protection against creditors than 401(k)s do in some states. If you're sued or face bankruptcy, a 401(k) has stronger federal protections. Also, you lose the ability to borrow against the balance—401(k)s allow loans; IRAs do not. And if you plan to return to work soon, rolling into an IRA now means you cannot easily move that money back into a future employer's 401(k) without complications around pre-tax versus after-tax contributions.

What happens if you receive a check instead of a direct rollover

Sometimes the old plan sends you a check instead of rolling the money directly. This is called an indirect rollover, and it triggers a 60-day window. You must deposit the full amount into another retirement account—a 401(k), traditional IRA, or Roth IRA—within 60 days, or the IRS treats the withdrawal as taxable income.

The check will show a withholding amount, usually 20% of the balance, sent to the IRS. If you deposit only the net amount you received, you'll owe taxes on the withheld portion when you file. To avoid this, deposit the full original amount (including the withheld portion from your own funds) into the new account within 60 days. When you file taxes, you'll recover the 20% withholding as a credit.

Missing the 60-day deadline means the full amount becomes taxable income for that year, plus a 10% early withdrawal penalty if you're under 59½. The IRS rarely grants extensions, so treat the 60 days as a hard deadline. Mark your calendar the day you receive the check.

Combining multiple IRAs into one IRA

If you have IRAs at different banks or brokerages, consolidating them into one account simplifies record-keeping and may reduce fees. This is simpler than moving 401(k)s because IRAs are not tied to employers.

Contact the IRA custodian where you want the money to land. Request a direct transfer (also called a trustee-to-trustee transfer) from each of your other IRAs. Provide the custodian with the account numbers and contact details of the other institutions. The receiving custodian coordinates with each sending custodian; the money moves directly between them, no tax withholding, no 60-day deadline.

You can also do an indirect rollover: withdraw money from one IRA and deposit it into another within 60 days. However, the IRS limits you to one indirect rollover per 12-month period across all your IRAs combined. If you have three IRAs and do one indirect rollover, you cannot do another indirect rollover from any of your IRAs for 12 months. Direct transfers have no such limit, so they're the safer route.

Tax and penalty considerations when combining accounts

A direct rollover—whether from 401(k) to 401(k), 401(k) to IRA, or IRA to IRA—incurs no immediate tax. The money remains in a tax-deferred account and grows without triggering a taxable event. You pay taxes only when you withdraw money in retirement.

An indirect rollover (receiving a check) triggers 20% withholding automatically. If you don't replace the withheld amount within 60 days, you'll owe taxes on it. An indirect rollover also counts against your one-per-year limit if you're moving IRAs.

If you're under 59½ and you miss the 60-day deadline on an indirect rollover, the IRS treats it as an early withdrawal. You'll owe income tax on the full amount plus a 10% penalty. Exceptions exist—disability, medical expenses, and a few others—but they're narrow. Always use a direct rollover when possible.

What to do before you leave your job

Before your last day, contact your old plan's administrator and ask for a rollover form or instructions. Find out whether your new employer's plan accepts rollovers. If it does, get the plan's custodian name and account routing details. If it doesn't, decide whether you want to open an IRA and which custodian to use.

Request a direct rollover in writing. Do not ask for a check. If the plan insists on mailing you a check, confirm the 60-day deadline in writing and mark your calendar immediately upon receipt. Keep copies of all rollover forms and correspondence.

If your old 401(k) balance is small—under $5,000 at some plans—the employer may force you to move it or cash it out. If they cash it out and send you a check, you still have 60 days to roll it into another account. Do not spend the money; deposit it immediately.

Frequently Asked Questions

Can I combine a Roth 401(k) with a traditional 401(k)?

You can roll a Roth 401(k) into a Roth IRA without tax consequences. Rolling a Roth 401(k) into a traditional IRA triggers taxes on the pre-tax portion of the balance. Rolling a traditional 401(k) into a Roth IRA is a conversion and creates a taxable event. Keep Roth and traditional accounts separate unless you understand the tax impact.

What if my old employer's plan is still open but I've left the company?

You can leave the money there indefinitely, but most people move it to consolidate. Leaving it behind means paying two sets of fees and tracking two accounts. You can roll it out at any time, even years later, as long as the plan is still open.

Do I need to report a direct rollover to the IRS?

A direct rollover does not require you to report anything on your tax return. The old plan sends Form 1099-R to the IRS showing a rollover code, which tells the IRS no tax is due. Keep your rollover documentation for your records.

Can I roll a 401(k) into a Roth IRA?

Yes, but it's a conversion, not a rollover. You'll owe income tax on the full amount converted in that tax year. This makes sense only if you expect to be in a lower tax bracket now than in retirement, or if you want Roth's tax-free growth going forward.

What if I have an outstanding loan against my 401(k)?

You must repay the loan before rolling the account out. If you leave the job without repaying, the IRS treats the unpaid balance as a taxable withdrawal. You'll owe income tax and possibly a 10% penalty if you're under 59½. Contact your plan administrator about repayment options before you leave.
