Can You Move a 401(k) to a Roth IRA? Rules, Taxes and Steps

Often, yes—if the 401(k) money is eligible for distribution. IRS rules generally permit an eligible workplace-plan distribution to be rolled to an IRA, including a Roth IRA, but the plan determines when a distribution is available. Required minimum distributions, hardship distributions, and certain other payments are not eligible rollovers. [1] [3]

Two questions therefore come first: “May the plan distribute this money now?” and “What kind of money is being distributed?” A permitted distribution is not automatically tax-free. Pre-tax money moved to a Roth IRA is generally a taxable Roth rollover, while designated Roth money and after-tax contributions require different treatment.

Yes. A former employee commonly can request a distribution, although plan terms control the choices. A current employee may need a plan-defined distributable event. Some plans permit in-service distributions under stated conditions; others do not.

The summary plan description explains distribution provisions, and the administrator can describe the plan’s current process. [9] An in-plan Roth conversion and a rollover to a Roth IRA are different transactions: one stays inside the employer plan; the other changes both the account and the custodian.

One statement can contain several tax sources: pre-tax or designated Roth deferrals, after-tax non-Roth contributions, and employer money. Employer contributions are often pre-tax, although some plans may permit designated Roth contributions. Confirm the source ledger.

IRS guidance permits certain distributions containing pre-tax and after-tax amounts to be directed to multiple eligible destinations, but allocation rules and same-time distributions can be technical. [10] Ask for a source breakdown before assuming after-tax money can be isolated.

The previously untaxed portion moved from a qualified employer plan to a Roth IRA is generally included in gross income for that calendar year. Properly documented after-tax basis may receive different treatment. [6] The rollover remains reportable even if all or part of it is not taxable, so keep the plan statement, confirmation, and tax forms.

Taxable conversion income is combined with wages, pensions, investment income, Social Security, and other items on the return. It may occupy more than one marginal bracket. State income tax may also apply. Review how Roth conversions are taxed, how a conversion may interact with Medicare IRMAA, and ways conversion taxes may be paid. Compare the 2026 brackets and current Medicare thresholds with the Roth Conversion Tax-Bracket & IRMAA Calculator.

In a direct rollover, the plan sends the eligible distribution to the receiving IRA or issues a check payable to the receiving institution for the participant’s benefit. Mandatory 20% withholding generally does not apply. If the eligible employer-plan distribution is instead paid to the participant, the plan generally must withhold 20% of the taxable amount. [1] [2]

Neither route decides the ultimate tax. A pre-tax direct rollover to Roth is generally taxable without withholding. The direct method instead keeps money out of the participant’s hands and generally avoids the 60-day replacement problem.

Possibly. A plan may offer partial distributions or allow part of an eligible distribution to be rolled over, but those choices depend on its terms and processing rules. The administrator should confirm whether a partial amount is currently available and whether source-level restrictions apply.

A partial taxable rollover can be compared with no rollover or a larger amount. Smaller is not automatically preferable; review current tax, tax cash, future balances, and plan features.

An eligible distribution from a designated Roth account may generally be rolled to a Roth IRA. Contributions and earnings remain distinct, however, and a nonqualified Roth 401(k) distribution is not automatically tax-free just because the account says “Roth.” [4]

The designated Roth account’s five-taxable-year period generally does not carry into the Roth IRA. The Roth IRA’s own starting date and whether the distribution is qualified can affect later treatment. If the person already has a Roth IRA, its earlier five-year period may matter. Confirm basis, earnings, opening dates, and documentation before moving a nonqualified balance.

Maybe, but many plans restrict distributions while a participant remains employed. Some permit an in-service distribution after a specified age or another plan-defined condition. Some instead offer an in-plan Roth conversion. A plan can offer one, both, or neither.

Check the summary plan description and ask the administrator which sources are distributable now, whether a partial amount is allowed, and whether the proposed transaction leaves the plan or stays inside it. [9] Do not infer availability from a former coworker’s transaction or a different employer’s plan.

When an eligible employer-plan rollover distribution is paid to the participant, the plan generally withholds 20% of the taxable amount. Completing a rollover generally has a 60-day deadline, and rolling over the full gross amount usually requires replacing the withheld funds. [2]

For a fully taxable $100,000 eligible distribution, the plan would generally send $80,000 and remit $20,000 as withholding. Depositing only $80,000 generally leaves $20,000 taxable; an additional tax may apply before age 59½ unless an exception applies.

No. A required minimum distribution is not an eligible rollover distribution, so the RMD itself cannot be converted. A person subject to an RMD generally must satisfy the applicable RMD before moving additional eligible money through a Roth conversion. [5]

RMD timing can change transaction order. For current sequencing, read whether a Roth conversion counts toward an RMD. The evergreen Roth conversions before RMDs guide explains how earlier planning years differ from RMD years.

Use this checklist with the plan, receiving custodian, and qualified professionals. A “yes” answer does not by itself make a rollover appropriate.

• Is this a current or former employer’s plan?
• Does the plan allow a distribution now?
• Is the money pre-tax, designated Roth, after-tax, or a mixture?
• Are employer contributions pre-tax or designated Roth?
• Is a direct rollover available?
• How much taxable income could the move create?
• Could it affect withholding or estimated-tax payments?
• Could it affect Medicare IRMAA?
• Could it affect how much Social Security is taxable?
• Is an RMD due first?
• Does the account hold employer stock that may require separate analysis?
• Are plan-level benefits, creditor protections, fees, or investment options worth comparing?
• Who will prepare and review the tax reporting?

Employer stock can raise separate tax questions, and employer-plan protections or features may not follow money into an IRA. Publication 575 describes employer-plan tax rules, including special treatment that may apply in limited circumstances. [7] Identify these facts before the rollover.

This is an educational overview, not transaction instructions. Provider procedures and check-title requirements differ.

1. Confirm that the plan permits the distribution now.
2. Identify the pre-tax, designated Roth, after-tax, earnings, and employer-source balances.
3. Establish an eligible Roth IRA if one does not already exist.
4. Ask the receiving custodian for its rollover instructions and account details.
5. Request a direct rollover from the plan rather than a distribution payable to you.
6. Confirm exactly how any check should be titled and where it should be sent.
7. Keep the request, confirmation, statements, deposit record, and tax forms.
8. Coordinate separate withholding or estimated payments as appropriate for the full-year tax picture.
9. Review Form 1099-R and the receiving custodian’s Form 5498 reporting for consistency.

Direct rollovers are reportable. Employer plans generally report distributions on Form 1099-R, and IRA trustees report rollover contributions on Form 5498. [8] Resolve any form mismatch before filing.

• Eligible 401(k) money can often be rolled to a Roth IRA, but the plan controls when a distribution is available.
• Pre-tax money moved to Roth is generally taxable in the rollover year; Roth and after-tax sources require separate records.
• A direct rollover generally avoids mandatory 20% withholding, but it does not eliminate the income tax on pre-tax money.
• A check paid to the participant generally brings 20% withholding, a 60-day deadline, and a possible need to replace withheld funds.
• An RMD is not eligible for rollover and cannot itself be converted.
• Plan features, tax brackets, Social Security, IRMAA, state tax, and payment method may be worth reviewing together.
