Your Four Main 401(k) Rollover Options
Option 1: Leave the Money in Your Former Employer’s 401(k)
You may be able to leave your money in your old 401(k), depending on the plan rules and your account balance. This can be a reasonable option if the plan has low fees, strong investment choices, institutional funds, or features you want to keep.
Leaving the account in place may also preserve certain plan protections and simplify timing if you are not ready to make a decision. However, an old 401(k) can become easy to ignore, especially if you change jobs multiple times.
Best for: People with a strong old plan, low fees, good investment options, and no immediate need to consolidate.
Option 2: Move the Money to a New Employer’s 401(k)
Some employer plans allow incoming rollovers from a prior 401(k). This can keep your retirement assets in one workplace plan and may simplify payroll contributions, investment monitoring, and account management.
A new employer plan may also be useful if it offers low-cost funds, institutional pricing, loan access, or planning features you value. However, employer plans are not required to accept rollover contributions, so you need to confirm the plan rules first.
Best for: People who want consolidation inside their current workplace plan and whose new 401(k) has competitive fees and investment options.
Option 3: Roll the 401(k) Into an IRA
A 401(k)-to-IRA rollover is one of the most common options. It can provide broader investment choice, more account control, easier beneficiary planning, and more flexibility in how assets are managed.
A rollover IRA may also make it easier to work with an advisor, coordinate retirement income, and consolidate old plans. The tradeoff is that IRAs may have different creditor protections, advisory fees, investment costs, and rules than employer plans.
Best for: People who want more investment flexibility, advisor guidance, account consolidation, or a more customized retirement income strategy.
Option 4: Convert the 401(k) to a Roth IRA
A rollover 401k to Roth IRA strategy moves pre-tax 401(k) assets into a Roth IRA. This is usually taxable in the year of conversion, but future qualified Roth IRA withdrawals may be tax-free.
This option can be powerful for people who expect higher future tax rates, want tax diversification, or want to reduce future pre-tax retirement balances. It can also be costly if the conversion pushes you into a higher tax bracket or triggers income-based costs.
Best for: People who can manage the current tax bill and want long-term tax-free Roth potential.

How to Rollover a 401(k), Step by Step
Step 1: Review Your Old 401(k)
Start by reviewing your old plan’s fees, investment options, account balance, Roth and pre-tax balances, outstanding loans, and distribution rules. You should also check whether the plan has special features you may lose by leaving.
If you have both traditional and Roth 401(k) money, treat them carefully. Pre-tax dollars and Roth dollars generally need to move to the correct destination accounts to avoid tax issues.
Step 2: Compare Destination Accounts
Next, decide where the money may go. Your destination could be a new employer’s 401(k), a traditional IRA, a Roth IRA, or some combination of accounts.
This is where tax planning becomes important. Rolling pre-tax 401(k) money to a traditional IRA is generally different from converting pre-tax 401(k) money to a Roth IRA. A Roth conversion may create taxable income in the year of conversion.
Step 3: Choose a Direct Rollover When Possible
A direct rollover usually moves retirement funds from the old plan directly to the receiving IRA or employer plan. The check may be payable to the receiving institution for your benefit, but not payable directly to you.
This approach is often preferred because mandatory 20% withholding does not apply when the funds are rolled directly to another retirement plan or IRA.
Step 4: Avoid Indirect Rollover Mistakes
An indirect rollover happens when the distribution is paid to you and you are responsible for redepositing it into another eligible retirement account. This can create avoidable tax risk.
If an eligible rollover distribution from an employer plan is paid to you, the plan generally must withhold 20% for federal tax, even if you intend to roll the money over later. To complete a full rollover, you may need to replace that withheld amount from other funds.
Step 5: Confirm the Rollover Was Completed
After the transfer, confirm that the funds landed in the correct account and were invested according to your plan. Do not assume the rollover is complete just because paperwork was submitted.
Keep copies of rollover forms, account statements, Form 1099-R, and any tax documents connected to the transaction. These records can help your tax preparer correctly report the rollover.
Major 401(k) Rollover Tax Traps
The 60-Day Rule
If you receive rollover funds directly, you generally have 60 days to redeposit the money into an eligible retirement account. If you miss the deadline, the distribution may become taxable and may also be subject to the 10% additional tax if you are under age 59½ and no exception applies.
This is one reason direct rollovers are usually cleaner. They reduce the risk of missing the 60-day window and avoid having the funds pass through your personal bank account.
The 20% Withholding Rule
For an indirect rollover from an employer plan, mandatory 20% federal withholding generally applies when the eligible rollover distribution is paid to you. This can create a cash-flow problem.
Example: if you take a $100,000 indirect rollover, the plan may send you $80,000 and withhold $20,000. To roll over the full $100,000, you would need to deposit $100,000 into the new account within 60 days, using $20,000 from other funds.
Roth Conversion Taxes
A rollover from a pre-tax 401(k) to a traditional IRA is generally different from a Roth conversion. If you move pre-tax 401(k) dollars into a Roth IRA, the taxable amount is generally included in income for that year.
That does not mean a Roth conversion is bad. It means the timing matters. A partial conversion over several years may be more efficient than converting a large balance all at once.
Required Minimum Distributions
If you are already subject to required minimum distributions, you generally need to handle the RMD correctly before rolling over the remaining eligible balance. RMDs themselves are not eligible for rollover.
This is an area where advisor and tax-professional coordination can help prevent reporting errors and accidental excess contributions.
After-Tax and Roth 401(k) Dollars
Some 401(k) plans include after-tax contributions, Roth 401(k) contributions, or both. These balances need careful handling because different tax rules may apply.
Moving Roth 401(k) money to a Roth IRA can be different from converting pre-tax 401(k) money to a Roth IRA. The destination account, source dollars, and account history all matter.
When a 401(k)-to-IRA Rollover May Make Sense
A 401(k)-to-IRA rollover may make sense when you want more investment flexibility, better coordination with an advisor, or a single place to manage retirement assets. An IRA may also provide more choices for income planning, beneficiary strategy, and portfolio customization.
It may not be the best choice if your 401(k) has unusually low costs, valuable institutional funds, or plan features you want to preserve. The decision should compare the actual old plan, the receiving IRA, and your retirement goals.
When a Rollover 401k to Roth IRA May Make Sense
A rollover 401k to Roth IRA strategy may make sense if you expect future tax rates to be higher, have cash outside the retirement account to pay conversion taxes, or want more tax-free income flexibility later.
It may also help retirees who want to reduce future pre-tax account balances and manage future required minimum distributions. However, Roth conversions can increase current taxable income, affect Medicare premiums, and interact with the Roth conversion 5 year rule.
Why an Advisor Helps With a 401(k) Rollover
A 401(k) rollover involves more than filling out transfer paperwork. An advisor can help compare fees, evaluate investment choices, review plan rules, and coordinate the rollover with your broader retirement income plan.
An advisor can also help identify tax traps before they happen. That includes deciding whether to use a direct rollover, whether a Roth conversion makes sense, how much to convert, and how the move may affect taxes in the current year.
Most importantly, an advisor can help turn an old 401(k) into part of a coordinated retirement strategy instead of a disconnected account.
Frequently Asked Questions About 401(k) Rollovers
What are my 401(k) rollover options?
Your main 401(k) rollover options are to leave the money in your former employer’s plan, move it to a new employer’s plan, roll it into an IRA, or convert some or all of it to a Roth IRA. Each option has different tax, investment, and planning considerations.
The right choice depends on your age, account balance, fees, investment options, tax bracket, retirement timeline, and whether you want professional guidance. A direct rollover is often the cleanest way to move money without triggering avoidable withholding issues.
How do I rollover a 401(k) to an IRA?
To rollover a 401(k) to an IRA, open or confirm the receiving IRA, contact your old 401(k) provider, request a direct rollover, and provide the receiving institution’s instructions. The funds should be sent directly to the IRA custodian or made payable to that custodian for your benefit.
Once the rollover arrives, confirm the deposit and invest the money according to your retirement plan. Keep your rollover confirmation, statements, and tax forms so your tax preparer can properly report the movement of funds.
Is a 401(k) rollover taxable?
A direct rollover from a traditional 401(k) to a traditional IRA is generally not taxable when done correctly. The money remains in a tax-deferred retirement account, and taxes are generally paid later when distributions are taken.
A rollover from a pre-tax 401(k) to a Roth IRA is different. That is usually treated as a Roth conversion, meaning the taxable amount is generally included in income for the year of conversion.
What is the 60-day rollover rule?
The 60-day rollover rule applies when retirement funds are paid to you and you plan to redeposit them into another eligible retirement account. In general, you must complete the rollover within 60 days to avoid the distribution being treated as taxable.
This rule is a major reason many people choose a direct rollover instead. When funds move directly from the old plan to the new account, you reduce the risk of missing the deadline or accidentally creating a taxable distribution.
What is the 20% withholding rule on a 401(k) rollover?
If an eligible rollover distribution from an employer plan is paid directly to you, the plan generally must withhold 20% for federal income tax. This withholding can apply even if you intend to roll the money over within 60 days.
To roll over the full balance, you may need to replace the withheld 20% using other funds. If you only deposit the amount you received, the withheld amount may be treated as distributed and could become taxable.
Can I rollover a 401k to a Roth IRA?
Yes, you may be able to roll over a 401(k) to a Roth IRA, but the tax treatment depends on the type of money being moved. Pre-tax 401(k) dollars converted to a Roth IRA are generally taxable in the year of conversion.
This can be a valuable strategy, but it should be planned carefully. A rollover 401k to Roth IRA can affect your tax bracket, Medicare premiums, Social Security taxation, and Roth IRA withdrawal timing rules.
Should I move my old 401(k) to my new employer’s plan?
Moving an old 401(k) to a new employer’s plan may make sense if the new plan accepts rollovers, has strong investment options, and offers competitive costs. It can also help keep your workplace retirement assets consolidated.
However, not all employer plans accept rollover contributions, and some plans have limited investment menus or higher expenses. Compare the old plan, new plan, and IRA option before deciding.
Should I leave my 401(k) with my old employer?
Leaving your 401(k) with your old employer may make sense if the plan has low fees, strong funds, and useful features. It can also be a temporary option while you review your choices.
The downside is that old accounts are easy to neglect. If you leave money behind, make sure your beneficiary information, investment allocation, contact information, and online access stay current.
Why work with an advisor on a 401(k) rollover?
An advisor can help you compare rollover options, avoid tax mistakes, and decide whether an IRA rollover, new employer plan rollover, or Roth conversion best fits your retirement strategy. This is especially important when large balances or mixed account types are involved.
Advisor guidance can also help coordinate the rollover with income planning, tax brackets, RMDs, estate goals, and investment management. The value is not just moving the account; it is making the account work within a larger plan.
