You can convert a Roth 401(k) to a Roth IRA without owing income tax, because both accounts hold money you’ve already paid tax on. The cleanest way is a direct rollover from your plan straight to a Roth IRA custodian. The one detail that trips people up: any employer matching contributions live in a separate pre-tax bucket inside your 401(k), and if you send that money into a Roth IRA by mistake, you’ll owe income tax on it in the year of the rollover.
When You Can Actually Do the Rollover
Your plan administrator won’t release the money on request. Federal rules require a qualifying event first. The most common one is leaving the job, whether you quit, are laid off, or retire.1Internal Revenue Service. 401(k) Resource Guide – Plan Participants – General Distribution Rules You also become eligible at age 59½, even if you’re still with the same employer.2Internal Revenue Service. When Can a Retirement Plan Distribute Benefits
If your company terminates its 401(k) plan without replacing it, all participants become fully vested and can roll their balances to an IRA.3Internal Revenue Service. Retirement Topics – Termination of Plan Some plans permit in-service distributions for active employees under 59½, but only if the plan document allows it. Ask HR or check your Summary Plan Description.1Internal Revenue Service. 401(k) Resource Guide – Plan Participants – General Distribution Rules
One boundary worth knowing: Roth IRA income limits don’t apply here. A rollover is a transfer of previously taxed retirement money, not a contribution, so it doesn’t count against the $7,500 annual IRA contribution cap for 2026 and isn’t blocked by high income.4Internal Revenue Service. Retirement Topics – IRA Contribution Limits You can roll over the entire balance and still make a separate annual contribution if you’re otherwise eligible.
Handle the Employer Match Separately
This is where most people get in trouble. Even though your own Roth 401(k) contributions are after-tax, employer matching money is always deposited into a separate pre-tax account inside the plan.5Internal Revenue Service. Retirement Plans FAQs on Designated Roth Accounts
The clean approach is a split distribution. Your Roth contributions and their earnings go to a Roth IRA. The pre-tax match goes to a Traditional IRA. If you instead route the pre-tax match into the Roth IRA, the IRS treats that as a taxable Roth conversion, and you’ll owe ordinary income tax on the full pre-tax amount for the year. That conversion is irrevocable.5Internal Revenue Service. Retirement Plans FAQs on Designated Roth Accounts For a large match balance, the tax bill can be sizable. When you fill out the distribution paperwork, tell the administrator explicitly to separate the two portions and send each to the right account.
Direct Rollover, Not Indirect
You have two ways to move the money, and only one of them makes sense in most cases.
A direct rollover, sometimes called a trustee-to-trustee transfer, sends funds straight from the 401(k) plan to the Roth IRA custodian. No taxes are withheld, no clock is ticking, and the one-per-year IRA rollover limit doesn’t apply to plan-to-IRA transfers.6Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions The mandatory 20% federal withholding that applies to eligible rollover distributions is waived when you elect a direct rollover.7eCFR. Withholding on Eligible Rollover Distributions; Questions and Answers
An indirect rollover puts the money in your hands first. The plan withholds 20% of the taxable portion for federal taxes before sending you the balance.8Internal Revenue Service. Topic No. 413, Rollovers From Retirement Plans You then have 60 days to deposit the full original amount into a Roth IRA. To roll over the complete balance, you have to replace the withheld 20% out of pocket, then wait to recover it when you file your taxes. Anything not redeposited within 60 days is treated as a distribution and can trigger a 10% early withdrawal penalty if you’re under 59½.6Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions
Choose the direct rollover. The indirect route only makes sense if you need short-term access to the funds and are certain you can redeposit everything on time.
Steps to Complete the Rollover
- Open a Roth IRA first if you don’t already have one. Setting up the receiving account before you start the distribution request avoids delays.
- Gather the receiving details: the custodian’s legal name, mailing address for incoming rollovers, and your Roth IRA account number. If you have a pre-tax employer match, open a Traditional IRA too and get its details.
- Request the distribution from your 401(k). Contact the plan administrator or use the plan’s online portal. Specify a direct rollover, and if a check is issued, make sure it’s payable to your new custodian “for the benefit of” (FBO) you.
- Instruct the plan to split the Roth contributions and pre-tax match into their respective IRAs.
- Confirm receipt. Processing typically takes five to ten business days. Once the money arrives, check that it’s invested rather than sitting in a default cash sweep.
Some plans mail the check to your home even for direct rollovers. As long as it’s payable to the IRA custodian and not to you personally, it’s still a direct rollover. Forward it to the custodian promptly.
The Roth IRA Five-Year Clock
A Roth IRA has its own five-year holding period that must pass before earnings can come out tax-free. The clock starts January 1 of the first year you make any contribution or rollover into any Roth IRA in your name.9Office of the Law Revision Counsel. 26 USC 408A – Roth IRAs It’s an individual clock, not an account clock.
If you already had a Roth IRA open five or more years ago, your clock is satisfied and the rolled-over money is immediately eligible for qualified tax-free withdrawals once you’re also 59½.9Office of the Law Revision Counsel. 26 USC 408A – Roth IRAs If this rollover opens your first-ever Roth IRA, the five-year clock starts now, no matter how long the Roth 401(k) existed. Pulling earnings before both the five-year mark and age 59½ means those earnings are taxed as ordinary income, plus a 10% early withdrawal penalty if you’re under 59½.10Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions
The ordering rules soften this. Roth IRA distributions come out in a set order: direct contributions first, then converted and rolled-over amounts, and earnings last. You’d have to drain the entire contribution and rollover layer before touching taxable earnings, so early access to some of the money is usually possible without a tax hit.
If You Have an Outstanding 401(k) Loan
An unpaid 401(k) loan complicates things. When you leave the employer, the plan typically requires repayment within a short window, often 60 to 90 days. If you can’t repay, the balance becomes a plan loan offset, which the IRS treats as a distribution.
You can still roll over the offset amount. For a qualified plan loan offset, the deadline is your tax filing due date, including extensions, for the year the offset occurs. Filing a six-month extension pushes that deadline from mid-April to mid-October. Miss it, and the offset amount becomes taxable income for the year, plus the 10% penalty if you’re under 59½.11Internal Revenue Service. Plan Loan Offsets You’ll need cash on hand, since you’re essentially replacing the loan balance with personal funds deposited into the Roth IRA.
How It Shows Up at Tax Time
Your former plan administrator will issue a Form 1099-R for the year of the rollover. For a direct Roth-to-Roth rollover, Box 7 should show Code H, and Box 2a (taxable amount) should show $0.12Internal Revenue Service. Instructions for Forms 1099-R and 5498 You report the rollover on Form 1040, but the taxable amount is zero as long as the Roth portion went to a Roth IRA.
If the distribution also included a pre-tax employer match rolled into a Traditional IRA, that portion gets its own 1099-R with a different code. If instead you sent the pre-tax match into the Roth IRA, that 1099-R will show a taxable amount and you’ll owe income tax on it. Hold onto all 1099-Rs and rollover confirmations for at least seven years.
Two Things to Weigh Before Moving a Large Balance
Creditor Protection Is Different in an IRA
An ERISA-qualified 401(k) has broad federal creditor protection, in and out of bankruptcy. An IRA’s shield is narrower. In federal bankruptcy, traditional and Roth IRA assets are protected up to $1,711,975, a cap in effect through 2028.13Office of the Law Revision Counsel. 11 U.S. Code 522 – Exemptions Amounts rolled over from employer plans into an IRA don’t count against that cap, so rollover money keeps unlimited bankruptcy protection. Outside bankruptcy, IRA creditor protection depends on state law and varies widely. If you work in a high-liability profession or face possible claims, talk to an attorney before moving the money.
Company Stock and NUA
If your Roth 401(k) holds company stock with significant unrealized gains, rolling it into a Roth IRA gives up a strategy called net unrealized appreciation, or NUA. Under NUA rules, you can distribute the stock into a taxable brokerage account, pay ordinary income tax only on the original cost basis, and have all the appreciation taxed at long-term capital gains rates when you eventually sell. Once the shares land inside a Roth IRA, that option is gone for good. For most people this doesn’t matter. For anyone sitting on highly appreciated employer shares, get tax advice before completing the rollover.
