How to Roll Over an Old 401(k): Direct Rollover vs. Roth Conversion (2026)
When you leave a job, you may have several choices for your old 401(k) account. Depending on the rules of the plan, you may be able to leave the money in the old plan, move it to a new employer plan, roll it into an IRA, or take a distribution.
A direct rollover can help you move retirement money without having the funds paid directly to you first. However, the tax result depends on the type of account you have and the destination you choose.
Important Difference
A direct rollover from a Traditional 401(k) to a Traditional IRA is generally not taxable at the time of transfer. Moving Traditional 401(k) money to a Roth IRA is a Roth conversion and generally creates taxable income for that year.
1. Review Your Options Before Moving an Old 401(k)
Before requesting a rollover, review the choices available to you. The best option can depend on plan fees, investment choices, creditor protections, employer matching rules, taxes, and whether you expect to make Roth conversions later.
| Possible Choice | General Consideration |
|---|---|
| Leave money in the former employer plan | You may keep the plan’s investment options and protections, but fees and account access can vary. |
| Move money to a new employer plan | This may simplify accounts if the new plan accepts rollovers and has suitable options. |
| Direct rollover to a Traditional IRA | Usually keeps pre-tax retirement money tax-deferred and may offer more investment choices. |
| Direct rollover or conversion to a Roth IRA | May create taxable income if the source money is pre-tax. Roth 401(k) money may have different treatment. |
| Take a cash distribution | This can create current income taxes and may trigger an additional early-distribution tax unless an exception applies. |
2. Know the Difference Between a Direct Rollover and a Roth Conversion
These terms are often used together, but they are not the same.
| Source Account | Destination Account | General Tax Result |
|---|---|---|
| Traditional 401(k) | Traditional IRA | Generally no current federal income tax when completed as a direct rollover. |
| Traditional 401(k) | Roth IRA | Generally taxable as a Roth conversion because pre-tax money is moving to a Roth account. |
| Roth 401(k) | Roth IRA | Generally a Roth-to-Roth rollover. Confirm the plan’s records and Roth distribution rules before proceeding. |
A Traditional 401(k) to Roth IRA transfer may avoid a 10% early-distribution tax when handled correctly as a direct rollover or conversion, but it can still increase your taxable income for the year.
Conversion Cannot Usually Be Undone
A Roth conversion or rollover from a retirement plan to a Roth IRA generally cannot be recharacterized back to a Traditional IRA. Review the expected tax impact before approving the transfer.
3. Why a Direct Rollover Is Usually Safer
A direct rollover means the old plan sends the money directly to the receiving IRA provider or issues a check payable to the new institution for your benefit.
For example, a check may be payable to:
“FBO” means “For the Benefit Of.” A check made payable to the new financial institution for your benefit is generally treated as a direct rollover even when it is mailed to your home address.
When a plan pays eligible rollover money directly to you instead, the plan generally must withhold 20% for federal taxes. You then have 60 days to complete an eligible rollover and may need to replace the withheld amount from other funds to roll over the full original distribution.
4. Step-by-Step: How to Request a Direct Rollover
Step 1: Identify the Type of Money in Your Old 401(k)
Contact the old plan administrator or check your online account. Ask whether the account includes Traditional pre-tax money, Roth 401(k) money, after-tax employee contributions, employer matching contributions, loans, or other special balances.
This matters because each type of money may have different rollover and tax treatment.
Step 2: Open the Correct Receiving IRA
Before starting the transfer, open the receiving account with the institution you plan to use.
- Open a Traditional IRA if you are moving pre-tax 401(k) money without creating current taxable income.
- Open a Roth IRA if you are moving Roth 401(k) money or deliberately converting pre-tax money to Roth money.
Ask the receiving institution for its exact rollover instructions, account number, mailing address, and check-payee format.
Step 3: Request a Direct Rollover From the Old Plan
Contact the former employer’s 401(k) provider and request a direct rollover. Use clear language such as:
Do not describe a Traditional 401(k)-to-Roth IRA move as “tax-free.” Ask the plan provider to explain how the transfer will be reported and whether it will be treated as a taxable Roth conversion.
Step 4: Review the Tax and Withholding Election Carefully
If you are transferring Traditional 401(k) money to a Roth IRA, ask how the plan will report the taxable amount. The conversion amount may be included in your taxable income for the year.
Do not assume that withholding is unnecessary simply because the money moves directly. A direct conversion may avoid the mandatory 20% withholding that applies when funds are paid to you, but you may still owe federal and state taxes when you file your return.
Some people prefer to pay conversion taxes using money outside the retirement account. Using part of the retirement money for taxes can reduce the amount moved to the Roth IRA and may create additional tax consequences, especially before age 59½.
Step 5: Confirm the Transfer Was Completed Correctly
Keep records of the request, check, account statement, confirmation page, and any tax forms you receive.
The old plan may issue Form 1099-R, and the receiving institution may issue Form 5498. A rollover or Roth conversion may still need to be reported on your federal tax return even if the transfer was direct.
5. Special Issue: After-Tax Contributions Inside a 401(k)
Some 401(k) plans contain after-tax employee contributions in addition to Traditional pre-tax and Roth contributions. These after-tax contributions are different from Roth 401(k) contributions.
In some situations, a plan distribution can be split between destinations. For example, pre-tax amounts may go directly to a Traditional IRA while after-tax contributions go directly to a Roth IRA.
Because plan rules and tax reporting can be complex, ask the plan administrator for a breakdown of pre-tax, Roth, after-tax, employer-match, and earnings amounts before submitting instructions.
6. Common Mistakes to Avoid
- Taking the money personally when a direct rollover is available. This can trigger mandatory withholding and create a 60-day deadline.
- Calling a Roth conversion “tax-free.” Pre-tax 401(k) money converted to Roth money is generally taxable.
- Ignoring state income taxes. A Roth conversion may have state as well as federal tax consequences.
- Converting a large balance without checking the tax bracket impact. A large conversion may affect marginal taxes, Medicare premiums, tax credits, or other programs.
- Forgetting about a 401(k) loan. A loan offset can create special rollover deadlines.
- Not reviewing the receiving account. After a rollover, confirm that the money is in the intended account and review your investment choices separately.
Questions to Ask Before You Sign the Forms
- What types of money are in my old 401(k) account?
- Is the transfer a direct rollover, an indirect rollover, or a Roth conversion?
- Will any part of this transaction be taxable this year?
- Will the old plan withhold money for taxes?
- Will I receive Form 1099-R?
- Does my old plan have a loan, after-tax contributions, or employer-stock rules that require special handling?
- Will this affect my state taxes, Medicare premiums, or other income-based programs?
