A 403(b) to 401(k) rollover is a tax-free transfer as long as you have a qualifying reason to take money out of the 403(b), your new employer’s 401(k) will accept the funds, and the money moves directly between the two plans. Most people do this after leaving a nonprofit, school, or hospital job for a private-sector employer. The mechanics are routine when handled correctly, and expensive when they aren’t.
When You’re Allowed to Move the Money
The IRS won’t let you pull money out of a 403(b) on demand. You need what’s called a distributable event. The most common one is leaving the employer that sponsors the plan. Others include reaching age 59½, becoming disabled, or the plan terminating.
If you’re still working for the 403(b) employer, the rules tighten. Your own elective deferrals (the pretax money you contributed from each paycheck) generally can’t be withdrawn and rolled over until you turn 59½. That restriction sits in the tax code and applies regardless of what your plan document says. Employer contributions like matching funds may be available sooner, but only if the plan specifically allows in-service distributions and you’ve met the vesting requirements.
Before starting anything, pull up your plan’s Summary Plan Description. It spells out which distributions your specific plan allows and under what conditions. If you can’t find it, HR or the plan administrator can send a copy.
Confirm the New 401(k) Will Accept the Rollover
This is the step people skip and then regret. A 401(k) plan is not legally required to accept incoming rollovers. Whether your new employer’s plan takes rollover money is entirely up to its plan document.1Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions Most large employer plans do, some smaller ones don’t, and a few accept rollovers only from certain plan types.
Contact the new 401(k) administrator before filing paperwork with your old 403(b). Ask specifically whether they accept rollovers from 403(b) plans, and whether they accept both pretax and Roth rollover contributions. Getting the answer in writing keeps you from starting a distribution you can’t complete on the other end.
Do a Direct Rollover
A direct rollover is the cleanest path. The 403(b) custodian sends the funds straight to the 401(k) custodian, and you never personally receive a check. Because you never take possession of the money, no taxes are withheld and no penalties apply.
The steps:
- Request a distribution and rollover form from your 403(b) administrator, designating the new 401(k) plan as the payee.
- Get the receiving plan’s details from the new 401(k) administrator: plan name, account number, and mailing address or wire instructions.
- Submit the paperwork. The 403(b) custodian issues a check or wire payable to the new plan’s trustee, typically labeled “FBO [Your Name]” (for the benefit of).
You may physically handle the check in transit, but you’re just a courier. The check is made out to the plan, not to you, which is what keeps it tax-free. This method avoids the mandatory 20% federal withholding that applies when distribution checks are made payable to participants.2eCFR. 26 CFR 31.3405(c)-1 – Withholding on Eligible Rollover Distributions
One concern you can set aside: the once-per-year rollover limit doesn’t apply here. That rule covers IRA-to-IRA rollovers only and specifically excludes plan-to-plan transfers.1Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions
Why the Indirect Rollover Usually Backfires
An indirect rollover happens when the 403(b) plan writes the check to you instead of to the new plan. It’s legal, but it creates problems immediately.
The plan is required to withhold 20% for federal income taxes before cutting the check.2eCFR. 26 CFR 31.3405(c)-1 – Withholding on Eligible Rollover Distributions You can’t opt out. If your 403(b) balance is $100,000, you receive a check for $80,000. To complete the rollover and avoid tax on the full amount, you must deposit $100,000 into the new 401(k) within 60 days. That means finding $20,000 from your own savings to bridge the gap.
Deposit only the $80,000 and the missing $20,000 is treated as a taxable distribution. You’ll owe income tax on it at your ordinary rate, plus a 10% early withdrawal penalty if you’re under 59½.3Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions You’ll eventually recover the withheld $20,000 as a refund when you file, but that could be months later.
The 60-day deadline is firm. Miss it by a day and the unredeposited amount becomes taxable income for that year. If you miss it through no fault of your own, the IRS offers a self-certification process under Revenue Procedure 2016-47, covering situations like financial institution errors, serious illness, a family member’s death, a misplaced check, or a natural disaster.4Internal Revenue Service. Revenue Procedure 2016-47 – Waiver of 60-Day Rollover Requirement You must complete the contribution within 30 days after the obstacle clears. Self-certification is not a guaranteed safe harbor; the IRS can still review the claim.
Roth 403(b) Money Has Its Own Path
Designated Roth contributions in your 403(b) can only roll into a designated Roth account inside the new 401(k). They cannot go into a pretax 401(k) account.5Internal Revenue Service. Rollover Chart The receiving 401(k) must actually have a Roth option. If it doesn’t, a Roth IRA is your fallback.
There’s an extra wrinkle. In a direct trustee-to-trustee rollover, both your basis (the original Roth contributions) and the earnings transfer together into the new Roth 401(k). In an indirect rollover where the check is payable to you, only the earnings portion can be rolled into another designated Roth account; the basis portion can only go into a Roth IRA at that point.6Internal Revenue Service. Retirement Plans FAQs on Designated Roth Accounts Another reason to stick with the direct method, especially for Roth money.
Outstanding Loans From the 403(b)
If you have an unpaid loan against your 403(b) when you leave, the remaining loan balance is typically offset against your account. The IRS treats that offset as an actual distribution.7Internal Revenue Service. Plan Loan Offsets Without action, you’ll owe income tax on the offset amount plus the 10% early withdrawal penalty if you’re under 59½.
You can roll over the offset amount into an eligible retirement plan to avoid the tax hit, and the deadline is more generous than the usual 60 days. If the offset happened because you left the job or the plan terminated, it qualifies as a qualified plan loan offset, and you have until your tax filing deadline, including extensions, to complete the rollover.7Internal Revenue Service. Plan Loan Offsets That typically means April 15 of the following year, or October 15 with an extension. You’ll need cash equal to the loan balance to deposit into the new plan, since the loan money is already gone from your account.
Annuity Contracts and Surrender Charges
Many 403(b) plans hold money in annuity contracts issued by insurance companies rather than in mutual funds. If your account is in an annuity, you’ll generally need to liquidate the contract before the rollover can proceed, because most 401(k) plans accept only cash transfers.
Liquidating an annuity before its maturity period expires usually triggers surrender charges. These fees vary by contract but commonly start in the range of 5% to 7% in the first year and decrease by about one percentage point each year until they disappear, often after six to eight years. Check your contract for the specific schedule. If you’re close to the end of the surrender period, waiting a few months can save thousands of dollars.
If your 403(b) assets sit in a custodial account (sometimes called a 403(b)(7) account), the process is simpler. These hold mutual funds rather than annuity contracts, so there are typically no surrender charges. The custodian liquidates the positions and sends cash to the new plan. Either way, plan for a brief window when the money is out of the market during liquidation and transfer.
After-Tax Contributions Get Special Treatment
Some 403(b) plans allow traditional after-tax contributions, separate from both pretax deferrals and Roth. Any distribution from an account containing both pretax and after-tax money must include a proportional share of each; you can’t cherry-pick just the after-tax dollars.8Internal Revenue Service. Rollovers of After-Tax Contributions in Retirement Plans
Under IRS Notice 2014-54, you can split a single distribution across multiple destinations. The pretax portion can go to the new 401(k) or a traditional IRA, and the after-tax contributions can go to a Roth IRA. Earnings on those after-tax contributions are considered pretax and follow the pretax portion.8Internal Revenue Service. Rollovers of After-Tax Contributions in Retirement Plans The split requires careful coordination with both plan administrators.
Consider Whether an IRA Is the Better Home
Rolling into the new 401(k) isn’t automatically the right call. A traditional or Roth IRA is worth considering, especially if the new plan has limited investment options or high fees. A few things to weigh:
- A 401(k) offers a curated menu chosen by the plan sponsor. An IRA lets you invest in virtually anything, including individual stocks, ETFs, and bond funds from any provider.
- Some 401(k) plans charge administrative fees on top of fund expenses. Compare the total cost against an IRA at a low-cost brokerage.
- Money in a 401(k) has strong federal protection under ERISA against most creditors. IRA protection varies by state and is generally weaker outside of bankruptcy.
- A 401(k) may let you borrow against your balance. IRAs never allow loans.
- If you’re still working past age 73 and don’t own more than 5% of the company, a 401(k) may let you delay required minimum distributions. Traditional IRAs have no such exception.
If creditor protection or 401(k) loan access matters, the new plan makes sense. If you want the widest investment choices and lowest fees, an IRA is usually the better home. You can also split the rollover, sending some to the 401(k) and some to an IRA, if the 401(k) plan permits partial rollovers and each portion is handled correctly.
