A rollover contribution moves money from one tax-advantaged retirement account into another without triggering income tax or early withdrawal penalties. Rollovers don’t count against the annual IRS contribution limits, so an entire 401(k) balance can shift into an IRA in a single transaction while tax-deferred growth stays intact. The rules that govern which accounts can send and receive funds, how the money physically moves, and when taxes get withheld are where most people run into trouble.
Which Accounts Can Roll Into Which
Federal law defines a specific list of “eligible retirement plans” that can send and receive rollover funds: traditional IRAs, Roth IRAs, SEP-IRAs, SIMPLE IRAs, 401(k) and other qualified plans under Section 401(a), 403(b) plans used by nonprofits and schools, 403(a) annuity plans, and governmental 457(b) deferred compensation plans.1Legal Information Institute (LII). 26 USC 402(c)(8)(B) – Eligible Retirement Plan Definition
Not every combination is permitted. Roth IRAs can only roll into other Roth IRAs. Designated Roth accounts inside a 401(k) or 403(b) can move to a Roth IRA or another designated Roth account, but not to a traditional IRA. SIMPLE IRAs impose a two-year waiting period before funds can roll into non-SIMPLE accounts. The IRS publishes a chart listing every allowed combination.2Internal Revenue Service. Rollover Chart
Even when the law allows a transfer, the receiving plan isn’t required to accept it. Some employer plans refuse incoming rollovers entirely or restrict them by account type. Confirm with the new plan administrator before starting anything. If the receiving plan rejects the funds after you’ve already taken a distribution, you’re racing the 60-day deadline to find another home for the money.3Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions
Inherited accounts sit apart from these rules. A surviving spouse can roll an inherited account into their own IRA and treat it as their own, which resets the distribution timeline to their own age. Non-spouse beneficiaries generally cannot roll inherited funds into their own retirement account. They must follow the 10-year distribution rule or, if they qualify as eligible designated beneficiaries, take distributions over their own life expectancy.4Internal Revenue Service.

Direct and Indirect Rollovers
How the money physically moves between accounts is the single most important decision in a rollover. It determines whether the IRS takes 20% off the top before the transfer even starts.
In a direct rollover, funds go straight from the old plan to the new one. You never touch the money. The check is made payable to the receiving institution “for the benefit of” you, or the transfer happens electronically between custodians. No taxes are withheld, and the transaction doesn’t trigger the one-per-year rule that applies to IRA-to-IRA rollovers.3Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions
In an indirect rollover, the distribution comes to you personally, and you deposit it into the new account yourself within 60 days. This is where things go sideways, because mandatory withholding kicks in the moment the check is cut in your name.
The 20% Withholding Trap
When an employer-sponsored plan pays a distribution directly to you rather than to another retirement plan, federal law requires the plan to withhold 20% for income taxes.5Office of the Law Revision Counsel. 26 USC 3405 – Special Rules for Pensions, Annuities, and Certain Other Deferred Income The plan administrator has no discretion here.
Consider a $50,000 balance in a 401(k). With an indirect rollover, the plan sends you a check for $40,000 and forwards $10,000 to the IRS. To complete a full rollover and avoid taxes on any portion, you have to deposit the entire $50,000 into the new IRA within 60 days, which means finding $10,000 of your own money to replace what was withheld. You’ll recover the withheld amount when you file your tax return, but you need to front the cash in the meantime.
If you only deposit the $40,000 you received, the IRS treats the missing $10,000 as a taxable distribution. You owe income tax on it, and if you’re under 59½, a 10% early withdrawal penalty on top of that.6Internal Revenue Service. Topic No. 557, Additional Tax on Early Distributions From Traditional and Roth IRAs A direct rollover avoids the withholding problem entirely, which is why almost every financial professional will steer you toward one.
Deadlines and Frequency Limits
Two timing rules govern indirect rollovers. Break either one and your transfer becomes a taxable event.
Once you receive a distribution, you have 60 days to deposit it into an eligible retirement plan. Miss that deadline and the entire amount becomes taxable income for the year you received it.7Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts The 10% early distribution penalty applies too if you’re under 59½.3Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions
The IRS allows waivers when the delay wasn’t really your fault. Under Revenue Procedure 2020-46, you can self-certify a late rollover if the cause was one of several specified circumstances, including a financial institution’s error, a misplaced check, serious illness, a family member’s death, incarceration, postal errors, or a delayed transfer of information from the distributing plan. You must complete the rollover within 30 days of the underlying problem being resolved, and the IRS can’t have previously denied a waiver for the same distribution.8Internal Revenue Service. Revenue Procedure 2020-46
For IRA-to-IRA indirect rollovers, you’re limited to one in any 12-month period. The clock starts on the date you receive the distribution, and the restriction applies across all your IRAs combined, not per account.7Office of the Law Revision Counsel. 26 USC 408 – Individual Retirement Accounts An indirect rollover in March 2026 rules out another until March 2027, even between completely different IRAs.
Direct trustee-to-trustee transfers are exempt from this limit. So are rollovers from employer plans like 401(k)s into IRAs. If you need to consolidate multiple IRAs, direct transfers between custodians let you move as many as you want without hitting the once-per-year ceiling.3Internal Revenue Service.

Amounts That Cannot Be Rolled Over
Required minimum distributions cannot be rolled into another retirement account.9Internal Revenue Service. Publication 590-B, Distributions From Individual Retirement Arrangements If you’ve reached the RMD age (currently 73, rising to 75 in 2033), you must take that year’s required distribution as taxable income before rolling over any remaining balance.
Any distribution you take counts toward satisfying your annual RMD first. Only the amount above your RMD for the year qualifies as an eligible rollover distribution.10eCFR. 26 CFR 1.402(c)-2 – Eligible Rollover Distributions Roll an RMD amount by mistake and you’ve made an excess contribution to the receiving account, which brings its own penalty problems.
Tax Consequences When the Account Type Changes
Moving money between accounts of the same tax type, traditional to traditional or Roth to Roth, generally creates no tax liability. Moving pre-tax money into a Roth account is a conversion, and the converted amount counts as ordinary income in the year of the transfer.11Internal Revenue Service. Retirement Plans FAQs Regarding IRAs A $100,000 conversion from a traditional 401(k) to a Roth IRA adds $100,000 to your taxable income for that year and can push you into a higher bracket.
That income spike carries secondary costs. The extra income can raise Medicare premiums through the income-related monthly adjustment amount, and it can bring investment earnings inside the 3.8% net investment income tax that would otherwise not apply.
Backdoor Roth Conversions and the Pro-Rata Rule
High earners whose income exceeds the Roth IRA contribution phaseout sometimes use a two-step approach. The 2026 phaseout starts at $153,000 for single filers and $242,000 for married couples filing jointly.12Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 The strategy is to contribute to a traditional IRA on a nondeductible basis (up to $7,500 in 2026, or $8,600 if age 50 or older), then convert those funds to a Roth IRA shortly afterward.13Internal Revenue Service. Retirement Topics – IRA Contribution Limits
Done cleanly, with no other pre-tax IRA balances, the conversion owes little or no tax because the contribution was already made with after-tax dollars. Any earnings that build up between the contribution and the conversion are taxable, which is why most people convert quickly.
The pro-rata rule is what catches people. If you already have traditional IRA money from deductible contributions or prior rollovers, the IRS treats all your traditional IRA balances as one pool. Every conversion draws proportionally from both pre-tax and after-tax funds, so part of the conversion becomes taxable even if you only meant to convert the nondeductible portion.14Internal Revenue Service. Rollovers of After-Tax Contributions in Retirement Plans If 80% of your combined IRA balance is pre-tax, 80% of any conversion is taxable. One common workaround is rolling the pre-tax IRA money into an employer 401(k) before converting, which removes it from the pro-rata calculation.
Employer Stock and Net Unrealized Appreciation
If your 401(k) holds highly appreciated company stock, rolling it into an IRA can cost you a valuable tax break. When employer stock is distributed as part of a lump-sum distribution and transferred to a regular brokerage account instead of an IRA, growth above the stock’s original cost basis is taxed at the lower long-term capital gains rate rather than as ordinary income.15Office of the Law Revision Counsel. 26 USC 402 – Taxability of Beneficiary of Employees Trust Roll the same stock into an IRA and every dollar of future distributions is taxed as ordinary income. The strategy applies only to employer securities and requires a qualifying lump-sum distribution, so consult a tax professional if your plan holds significant company stock.
How Rollovers Are Reported
Rollovers generate tax forms that both you and the IRS receive, so the numbers on your return need to match.
The distributing plan files Form 1099-R showing the gross distribution in Box 1. For a direct rollover, Box 7 contains distribution code G, and Box 2a (taxable amount) shows zero. Code H covers a direct rollover from a designated Roth account to a Roth IRA.16Internal Revenue Service. Instructions for Forms 1099-R and 5498 An indirect rollover generates a 1099-R showing the full distribution as potentially taxable, and you report the rollover on your tax return to show you redeposited the funds.
The receiving institution files Form 5498 to confirm it received the rollover funds, with the amount in Box 2.17Internal Revenue Service. Form 5498 – IRA Contribution Information Form 5498 doesn’t arrive until the following spring, so keep your own records of the deposit in the meantime.
A Roth conversion or a nondeductible contribution to a traditional IRA also requires Form 8606 with your tax return. This form tracks your after-tax basis in traditional IRAs and prevents you from paying tax twice on the same money.18Internal Revenue Service. Instructions for Form 8606 Skipping Form 8606 is one of the most common and most expensive mistakes in the backdoor Roth process, because without it the IRS has no record that you already paid tax on those contributions.
Steps to Complete a Rollover
The process varies depending on whether you’re moving funds from an employer plan or between IRAs, but the core sequence stays the same.
- Contact the receiving institution first. Confirm they accept rollovers from your account type and get their specific deposit instructions, including any required forms, the mailing address, and the exact payee name for checks.
- Request the rollover from the sending plan. For employer plans, fill out a distribution request form specifying a direct rollover to the new custodian, and provide the receiving institution’s name, address, and your new account number. For IRA transfers, the receiving custodian can often initiate the process on your behalf.
- Verify the check payee line. On a direct rollover, the check should be payable to the new custodian FBO your name, for example “Fidelity FBO Jane Smith.” A check made payable directly to you means you’re in indirect rollover territory and the 60-day clock is running.
- Deposit the funds promptly. Mail or upload the check to the receiving institution per its instructions. If the check is payable to the new custodian, don’t endorse it. Just include your account number. If it’s payable to you, endorse it and get it deposited well before the 60-day deadline.
- Confirm the deposit posted correctly. Check your new account for a transaction showing the rollover contribution. Electronic transfers typically take a few business days, while check-based rollovers involving mail can take several weeks from start to finish. If the funds don’t appear within a reasonable time, follow up with both institutions before the 60-day window closes.
Some employer plans charge an account-closing or transfer fee, often in the range of $50 to $100, though many large custodians have eliminated these fees. The receiving institution sometimes reimburses the charge if you ask, especially on larger balances. Check both sides before initiating the transfer so you aren’t surprised by a deduction from your rollover amount.
