An in service rollover moves vested money out of an employer 401(k) and into an IRA while you are still working for that employer, with no job change and no separation. It is allowed only when the plan document permits it and, for salary deferrals, generally once you reach age 59½ under IRC 401(k)(2)(B)(i)(III) (Source: 26 U.S. Code § 401, law.cornell.edu). Only the money changes custodian; your employment does not.
An in service rollover transfers 401(k) dollars into an IRA while you remain employed. Salary deferrals generally become distributable at age 59½ if the plan permits it (Source: IRC 401(k)(2)(B)(i)(III), 2026). A direct trustee-to-trustee rollover reports no income and avoids the mandatory 20% withholding and the 10% early-distribution tax (Source: IRS Topic No. 413 and Topic No. 558, 2026).
What is an in-service 401(k) rollover?
An in-service 401(k) rollover is the transfer of vested balances from an active employer 401(k) into an IRA before the employee separates from the job. The worker keeps the same employer, and only the money changes custodian. The feature is optional under federal law, so it applies only when the plan document specifically permits distributions to current employees (Source: 26 U.S. Code § 401, 2026).

An in-service rollover differs from the common post-separation rollover (covered on the general how to roll over a 401(k) to an IRA walkthrough): the participant is still on payroll, so the plan must grant an in-service distribution right, and most transfers are partial. Federal law lists the events on which elective contributions may be distributed, including attainment of age 59½ under subclause (III), only when the plan writes that option into its terms (Source: 26 U.S. Code § 401(k)(2)(B)(i), 2026).
Can you roll over a 401(k) while still employed?
Yes, you can roll over a 401(k) while still employed, but only if your plan permits in-service distributions and you meet the eligibility conditions. Industry surveys indicate more than 70% of plans allow some form of in-service withdrawal, yet the terms vary widely by contribution source and age. The right to move money comes from the plan document, not from being a long-tenured employee.
Vesting matters alongside plan permission: any unvested employer match stays in the plan and cannot be rolled, so a partial transfer confirms both which dollars are vested and which sources the plan releases in service.
At what age can you do an in-service rollover?
For salary deferrals, age 59½ is the primary threshold, because IRC 401(k)(2)(B)(i)(III) makes attainment of age 59½ a distributable event (Source: 26 U.S. Code § 401, 2026). Some plans release certain non-elective sources, such as profit-sharing contributions or prior rollover balances, at any age if the plan terms allow. Elective deferrals, QNECs, and QMACs are the sources most tightly restricted to the 59½ event.
Why “just call HR or read the SPD” can be wrong
The common advice to read the Summary Plan Description or call the administrator is a starting point, not a final answer. Front-line HR staff and call-center representatives are frequently wrong about in-service eligibility, because the feature sits in the plan’s optional distribution provisions. A verbal “no” is not proof the plan prohibits it. The authoritative source is the full plan document, specifically the section titled in-service withdrawals or in-service distributions, which states the minimum age, the eligible sources, and whether partial distributions are allowed. Requesting that language in writing reduces the risk of acting on a mistaken phone answer.
Can you do an in-service rollover before 59½?
In many plans, yes, but not from salary deferrals. Elective deferrals generally cannot be distributed in service before 59½ except for hardship. Other sources, such as profit-sharing contributions, non-safe-harbor match, and prior rollover balances, may be distributable at any age when the plan permits. A pre-59½ distribution that is not directly rolled over may face the 10% early-distribution tax (Source: IRS Topic No. 558, 2026).
As long as eligible funds go trustee-to-trustee into an IRA, the age does not create a taxable event, because a direct rollover is not a distribution. The 10% additional tax only applies if dollars are paid out and not rolled within the rules.
How is an in-service rollover taxed?
A properly executed direct in-service rollover to a traditional IRA is not a taxable event: funds move trustee-to-trustee, nothing is reported as income, and no early-distribution penalty applies (Source: IRS Topic No. 413, 2026). The tax result turns on the method. A direct rollover avoids withholding; an indirect rollover (a check paid to you) triggers mandatory 20% withholding and a 60-day redeposit clock.
| Method | Withholding | Deadline | Tax result if done correctly |
|---|---|---|---|
| Direct rollover (trustee-to-trustee) | None; mandatory 20% withholding does not apply (Source: IRS Topic No. 413, 2026) | No 60-day clock | Tax-free transfer; no income reported |
| Indirect rollover (check paid to you) | Generally 20% withheld from the taxable amount (Source: IRS Pub. 575, 2026) | 60 days to redeposit the full amount | Tax-free only if you replace the withheld 20% from other funds and redeposit 100% within 60 days |
| Pretax 401(k) to Roth IRA | Depends on election | December 31 for the conversion year | Taxable conversion; pretax amounts added to ordinary income (Source: IRS, 2026) |
A participant who takes an indirect rollover, receives 80%, and redeposits only that amount has the withheld 20% treated as a taxable distribution. The one-rollover-per-year limit does not apply to plan-to-IRA rollovers. Rolling pretax dollars into a Roth IRA is a taxable conversion; Q3 Advisors models that decision on its Roth conversion service page and its how much to convert to Roth guide.
What happens to after-tax 401(k) dollars?
Some 401(k) plans hold after-tax (non-Roth) contributions. Under IRS Notice 2014-54, effective for distributions on or after September 18, 2014, after-tax amounts can be directed to a Roth IRA while the pretax amounts go to a traditional IRA, treating simultaneous distributions to multiple destinations as a single distribution (Source: IRS Notice 2014-54, 2014). This split rollover lets the after-tax basis land in a Roth IRA tax-free. Absent that allocation, the pro-rata rule would generally require each distribution to carry a proportional share of pretax and after-tax dollars.
Should you roll over? Pros and cons
An in-service rollover generally trades the constraints of a 401(k) for the flexibility of an IRA, and each side carries costs. Weigh the IRA’s broader investment menu and consolidation against the loss of 401(k) loan access, differences in creditor protection, and fees, since large plans may offer institutional pricing an individual IRA cannot match. The rule of 55 also favors keeping money in the plan for some savers.
| Potential advantages | Potential disadvantages |
|---|---|
| Broader investment menu; 401(k) lineups are often limited | Loss of 401(k) loan access; a loan from an IRA is a prohibited transaction (Source: IRC 4975, 2026) |
| More control over holdings and beneficiary structure | Creditor protection differs; 401(k) assets are generally ERISA-protected, while IRA protection can vary by state outside bankruptcy (Source: ERISA § 206(d), 2026) |
| Possible access to lower-cost funds not on the plan menu | IRA advisory and fund fees can exceed institutional 401(k) pricing |
| Consolidation with other IRA assets and estate simplicity | Possible temporary suspension of 401(k) contributions after a distribution, depending on plan terms |
One timing point deserves weight: the rule of 55 lets someone who separates from an employer in or after the year they turn 55 take penalty-free 401(k) distributions, and that exception does not extend to IRAs (Source: IRC 72(t)(2)(A)(v), 2026), so moving money out early can end that access. IRAs also carry their own RMD timing (age 73, or 75 for those born in 1960 or later, first arriving in 2035), covered on the Q3 Advisors 2026 required minimum distributions page.
What about company stock? NUA and the employer-stock trap
Net Unrealized Appreciation (NUA) is a tax treatment for employer stock in a 401(k), governed by IRC 402(e)(4) (Source: IRC 402(e)(4); IRS Pub. 575, 2026). Rolling appreciated company stock into an IRA can permanently forfeit NUA. Under NUA, the stock’s cost basis is taxed as ordinary income at distribution to a taxable account, and the appreciation may later be taxed at long-term capital gains rates when the shares are sold.
In a hypothetical illustration, a 401(k) holds employer stock with a $50,000 cost basis now worth $250,000. Rolling all $250,000 into an IRA generally makes every future dollar withdrawn ordinary income. Using NUA and distributing the shares to a taxable account instead, ordinary income tax applies to the $50,000 basis now, while the $200,000 of appreciation may later be taxed at long-term capital gains rates (0%, 15%, or 20% by income). Because a blanket in-service rollover can sweep company stock into an IRA and end the NUA option, holders of appreciated shares often model NUA first.
Step-by-step: how to execute the transfer
An in-service rollover is a sequence of confirmations before money moves. In general the participant confirms eligibility in the plan document, confirms the vested balance, opens the receiving IRA, requests a direct trustee-to-trustee rollover payable to the IRA custodian, and selects investments once funds arrive. Requirements vary by plan and custodian, so each step is confirmed with them.
- Confirm eligibility in writing by reading the plan document’s in-service distribution section, not just the SPD summary, and identify which contribution sources and how much are eligible.
- Confirm the vested balance and decide whether the transfer is partial or full.
- Open the receiving IRA (traditional for pretax dollars, Roth for after-tax under Notice 2014-54) before requesting the distribution.
- Request a direct (trustee-to-trustee) rollover, with the check or wire payable to the IRA custodian for the benefit of the account holder, never payable to you.
- Choose investments inside the IRA once funds arrive, and keep the plan’s distribution confirmation for tax records.
2026 contribution limits while still contributing
Because an in-service rollover happens while you are still contributing, current limits set the backdrop. For 2026, the 401(k), 403(b), governmental 457, and TSP elective deferral limit is $24,500, the age-50 catch-up is $8,000, and the SECURE 2.0 catch-up for ages 60 to 63 is $11,250. The IRA limit is $7,500, or $8,600 with the $1,100 catch-up at age 50 and over (Source: IRS Notice 2025-67).
A rollover can ripple into other 2026 calculations. If pretax dollars are later converted to a Roth IRA, the added income can affect the 3.8% net investment income tax (above $200,000 single or $250,000 married filing jointly) and Medicare IRMAA on a two-year lookback. The 2026 Roth conversion deadline of December 31 is the fixed point that coordination works around.

Frequently asked questions
What is an in-service rollover?
An in-service rollover moves vested funds from an employer 401(k) into an IRA while the participant is still employed there. It is permitted only if the plan document allows in-service distributions and, for salary deferrals, generally once the participant reaches age 59½ under IRC 401(k)(2)(B)(i)(III) (Source: 26 U.S. Code § 401, 2026).
At what age can you do an in-service rollover?
For salary deferrals, age 59½ is the primary threshold, because IRC 401(k)(2)(B)(i)(III) makes attainment of age 59½ a distributable event (Source: 26 U.S. Code § 401, 2026). Some plans release non-elective sources, such as profit-sharing or prior rollover balances, at any age. The plan document controls.
Can you roll over a 401(k) while still employed?
Yes, if the plan permits in-service distributions and conditions such as age 59½ for deferrals are met (Source: 26 U.S. Code § 401, 2026). A direct trustee-to-trustee rollover is not a taxable event and avoids the mandatory 20% withholding and the 10% early-distribution tax; an indirect rollover generally does not.
How is an in-service rollover taxed?
A direct trustee-to-trustee rollover to a traditional IRA is tax-free, with no income reported and no penalty (Source: IRS Topic No. 413, 2026). An indirect rollover generally triggers mandatory 20% withholding and a 60-day redeposit deadline. Rolling pretax dollars into a Roth IRA is a taxable conversion that adds the pretax amount to ordinary income.
Are in-service rollovers always allowed?
No. In-service distributions are an optional plan feature. The Internal Revenue Code permits them but does not require plans to offer them, so a 401(k) may prohibit them or allow them only for certain sources (Source: 26 U.S. Code § 401, 2026). Eligibility is confirmed in the plan document, not by a phone call.
Can you do an in-service rollover before 59½?
Salary deferrals generally cannot be distributed in service before 59½ except for hardship. Other sources, such as profit-sharing contributions or prior rollover balances, may be available earlier if the plan permits. A pre-59½ distribution not directly rolled over may face the 10% early-distribution tax (Source: IRS Topic No. 558, 2026).
What are the disadvantages of an in-service rollover?
Factors to weigh include loss of 401(k) loan access (an IRA loan is a prohibited transaction under IRC 4975), weaker creditor protection since 401(k) assets are ERISA-protected while IRA protection varies by state, potentially higher IRA fees than institutional plan pricing, and the risk of forfeiting NUA on employer stock under IRC 402(e)(4).
Can you still contribute to your 401(k) after an in-service rollover?
In most cases yes, because the participant remains employed. However, some plans impose a temporary suspension of contributions after a distribution, depending on plan terms. Because 2026 deferral limits allow up to $24,500, or more with catch-up contributions, any suspension can reduce annual saving (Source: IRS Notice 2025-67).
