Leaving a job often forces a quick decision about what to do with the money saved in a 401k or 403b. 

Many people want a straightforward way to keep those funds tax-deferred and invested without leaving them behind in an old employer plan. A practical option is moving the balance into a type of IRA that accepts rollovers from workplace accounts. This transfer can maintain the account’s tax treatment and give you wider investment choices. It also helps you avoid penalties and taxes that can apply if you take the money out directly. 

Below we explain what a rollover IRA is, how this type of IRA works, and the situations where it may fit someone who wants more control over their retirement savings after leaving an employer.

How Does a Rollover IRA Work?

When you leave a job or lose eligibility for a workplace plan, the money in your 401k or 403b stays in the account until you choose what to do with it. The decision affects how your savings grow, how they are taxed, and how much control you have over investments. The options below outline the most common paths people review when handling an old employer-sponsored plan.

Options for Your Former Employer Plan

You generally have four choices. Each one has different tax results and long-term considerations.

1. Leave the balance in your old plan.

Some plans allow you to keep your assets if your account exceeds the plan’s involuntary cash-out threshold. Plans may set this limit up to $7,000 for distributions made in 2025. Leaving the balance can make sense if the plan offers strong investment options and competitive fees.

2. Withdraw the funds.

A withdrawal before age 59½ may trigger a 10% additional tax unless an exception applies. The amount withdrawn is also subject to income tax. This option ends future tax-deferred growth and can significantly reduce long-term savings.

3. Roll the balance to a new employer’s plan.

If your new plan accepts rollovers, this keeps your retirement money in one place. The investment choices depend on the plan’s menu and may offer fewer options than an IRA.

4. Roll the balance into a different retirement plan, such as a rollover IRA.

A direct rollover avoids mandatory withholding and helps you preserve tax-deferred growth. Many people choose this path for broader investment flexibility and easier long-term account management.

If you open a rollover IRA, you choose a provider, select either a Traditional or Roth account, and request a direct transfer from your former plan. This keeps the process simple and avoids accidental taxable distributions.

Difference Between a Traditional IRA and a Roth IRA

Traditional IRA:

  • Accepts pre-tax or after-tax contributions.
  • Contributions may be deductible depending on income and workplace plan coverage.
  • Growth is tax-deferred.
  • Withdrawals are generally taxed as ordinary income.

Roth IRA:

  • Funded with after-tax dollars, so contributions are not deductible.
  • Qualified withdrawals of earnings can be tax-free if the account meets requirements such as the five-year rule and age 59½.

Rollover tax treatment:

  • Moving pre-tax 401k funds to a Traditional IRA is generally not taxable when done correctly.
  • Moving pre-tax 401k funds to a Roth IRA is treated as a taxable conversion.
  • Roth 401k assets can roll into a Roth IRA tax-free in a direct rollover.

Difference Between a Rollover IRA and a Regular IRA

A rollover IRA and a regular IRA operate under the same general tax rules, withdrawal rules, and investment rules. Both accounts allow tax-deferred growth in a Traditional IRA and potential tax-free qualified withdrawals in a Roth IRA. The difference is not in how the accounts work. It is in how they begin and how the funds inside them are sourced.

A rollover IRA is opened to receive money from an employer-sponsored plan such as a 401k or 403b. This helps preserve tax-deferred status when you leave a job or retire. You can choose to set it up as a Traditional or Roth IRA, depending on the tax treatment of the funds you are receiving.

A regular IRA does not exist for rollover purposes by default, though it can accept rollovers if needed. Its distinction is simple. It is not created exclusively to receive funds from an employer-sponsored plan, and contributions often come from annual IRA contribution limits rather than plan distributions.

Can You Roll Funds Into an Existing IRA You Already Own?

Yes, you can roll assets from a workplace plan into an existing IRA. Pre-tax plan funds usually go into a Traditional IRA unless you choose to convert to a Roth IRA and pay income tax on the converted amount. Some people keep a separate rollover IRA for clarity and potential future flexibility.

Here are common reasons someone may keep rollover assets in a dedicated account:

✅ Easier record-keeping

  • Keeping rollover assets separate makes it clearer where the money came from.
  • This can be helpful when managing future rollovers or when documenting the source of funds.

✅ Possible future rollover to a new employer plan

  • Some employer plans accept rollovers only from another qualified plan or a rollover IRA.
  • Mixing rollover funds with regular IRA contributions can complicate eligibility.

✅ Creditor protection differences

  • Funds that originated in an employer-sponsored plan may receive stronger protection under federal bankruptcy law than regular IRA contributions.
  • Protections vary by state, so treatment depends on applicable state and federal rules.

📝 Note: Keeping rollover funds separate does not change how the account grows or how investments are chosen. It simply preserves a clear record of the assets’ history, which can matter in certain administrative or legal contexts. 

Are There Any Limits on How Much You Can Roll Over?

A rollover from a workplace retirement plan does not count toward your annual IRA contribution limit. You can move any amount from your employer-sponsored account and still have your full yearly contribution room available. This applies whether you roll assets to a Traditional or Roth IRA.

The annual contribution limit for a rollover IRA aligns with the limits for all IRAs. For 2025, you can contribute up to $7,000 if you are under age 50 or up to $8,000 if you are 50 or older. These limits apply only to new contributions. They do not restrict how much you roll over.

How to Transfer Your 401k to a Rollover IRA

Moving money from a 401k to a rollover IRA follows a straightforward sequence. You choose a provider, open the account as either a Traditional or Roth IRA, and request that your former plan transfer the funds. The rollover can be completed in one of two ways.

Types of Rollovers

Each method has different rules on withholding, timing, and how the transfer is handled.

Direct rollover

  • Funds move directly from your employer-sponsored plan to the rollover IRA.
  • You do not take possession of the money.
  • Mandatory withholding does not apply, and the transfer avoids early-distribution penalties.

Indirect rollover

  • The plan distributes the money to you first.
  • You have 60 days to deposit the full amount into your rollover IRA.
  • A 20% withholding applies when the plan issues the distribution to you. To complete a full rollover, you must replace the withheld amount within 60 days.
  • If you miss the deadline, the distribution may be taxable and may trigger a 10% additional tax if you are under age 59½ and no exception applies.

📝 Note: An indirect rollover introduces the risk of missing the 60-day deadline. A direct rollover removes this timing pressure.

How Long Does a 401k Rollover Take?

The timeline depends on the type of rollover you choose and the institutions involved.

Direct rollover:

A direct rollover does not have an IRS-mandated timeline. Processing speed varies by plan administrator and the receiving financial institution. Many are completed within days, though timeframes differ. 

Indirect rollover:

The process can extend to 60 days or more because you receive the funds first. The IRS gives you 60 days to deposit the full amount into your rollover IRA. The rollover is considered incomplete if the deposit is not made within that window.

Conclusion

A rollover IRA offers a straightforward way to move retirement savings from a former employer’s plan into an account you manage on your own terms. The transfer keeps tax-deferred growth in place and can expand your investment choices, depending on the provider you choose. The right approach depends on your needs, the type of IRA you prefer, and how you plan to use the funds in the future.
