401(k) Rollover Checklist: 15 Steps Before You Initiate (and 3 After)
Most rollover mistakes are irreversible. The indirect-rollover withholding trap, the Rule of 55 forfeit, the Backdoor Roth pro-rata disaster — once you've initiated, you can't undo them. This checklist walks through every decision and mechanics check you should complete before contacting your plan administrator. Phase 4 covers the three things to do once the rollover clears.
Phase 1 — Pre-decision checks
These six checks could change where you roll — or whether you roll at all. Each is a potential "stop, reconsider" trigger. Work through them before choosing a destination.
1. ☐ Rule of 55 check — are you 55–59½ and separating from this employer this year?
If yes, you may qualify for the Rule of 55: penalty-free distributions directly from this 401(k), without SEPP restrictions, until you reach 59½. The moment you roll that money to an IRA, the exception is permanently gone. There is no way to get it back once funds leave the plan.1
The fix if you need bridge income: keep the balance in the plan and take distributions there, then roll the remainder to an IRA at 59½ when the advantage expires. Or take a partial rollover — roll only what you don't need for early access. Not all plans allow partial distributions or installment payments; confirm with the plan administrator before assuming.

2. ☐ NUA check — do you hold highly appreciated employer stock?
If your 401(k) has employer stock (your company's own stock, not a mutual fund holding it) with a low cost basis, the Net Unrealized Appreciation strategy may let you pay long-term capital gains rates (0–20%) on all the appreciation — instead of ordinary income rates (up to 37%) that would apply if you roll to an IRA and later distribute. The NUA treatment disappears once the stock leaves the plan via rollover.2
Rule of thumb: NUA is worth considering when the appreciation (current value minus plan's cost basis) represents at least 30% of the position's current value. Below that threshold, the immediate tax on the distribution usually cancels the capital gains rate benefit.

3. ☐ Backdoor Roth check — do you use or plan to use the Backdoor Roth strategy?
If your income is above the Roth IRA direct-contribution limit ($165,000 single / $246,000 MFJ in 2026), you're probably using or planning the Backdoor Roth.3 Rolling pre-tax 401(k) money to a traditional IRA triggers the pro-rata rule: your future Backdoor Roth conversions become partially taxable in proportion to your total pre-tax IRA balance.
Example: you roll $150,000 pre-tax to an IRA, then make a $7,000 nondeductible Backdoor Roth contribution. Your conversion is 95.5% taxable ($150K pre-tax ÷ $157K total). Instead of a nearly tax-free conversion, you owe ordinary income tax on $6,685 — every year you use the strategy going forward.
Options: roll the old 401(k) into the new employer's plan (keeps IRA at zero), or leave it in the old plan and revisit after 59½.

4. ☐ Loan offset check — do you have an outstanding 401(k) loan balance?
If you leave a job with an unpaid 401(k) loan, the plan offsets (reduces) your account balance by the loan amount and issues a 1099-R treating it as a taxable distribution — plus a 10% penalty if you're under 59½.
Under TCJA 2017, you have until your tax filing deadline including extensions (October 15 of the following year for most people) to contribute the offset amount to a new IRA or 401(k) and reverse the tax consequence.4 This is called a Qualified Plan Loan Offset (QPLO). The standard 60-day rollover window no longer applies to QPLOs.

5. ☐ Vesting cliff check — have you fully vested in employer contributions?
Your own salary deferrals are always 100% yours. Employer matching and profit-sharing contributions vest according to a schedule — three-year cliff or six-year graded are common under ERISA. Leave before you cross the cliff and you forfeit the unvested balance permanently. The forfeiture happens when you leave, not when you roll — but it affects the amount you'll have to roll.

6. ☐ In-service rollover check — are you still employed?
If you're 59½ or older and still working, check whether your current plan allows in-service distributions. If so, you may be able to roll part or all of your existing 401(k) to an IRA right now — opening Roth conversion runway, lower-cost funds, and greater investment flexibility up to 13 years before your RMDs begin. This is not applicable to job-changers; it's for people who want to access rollover benefits without leaving their employer.
Phase 2 — Pre-initiation setup
Once you've decided to roll, four things to confirm before you call the plan administrator.
7. ☐ Open the destination account first
Open the IRA (or confirm the new employer's 401(k) accepts incoming rollovers) before requesting the distribution. This prevents the scenario where a check arrives and you're scrambling to open an account during the 60-day window. A traditional IRA opened the same day you initiate is fine — funds don't arrive immediately anyway.
→ Fidelity vs. Vanguard vs. Schwab for rollover IRA
8. ☐ Stable value equity wash restriction check
Many 401(k) plans with stable value funds prohibit direct transfers from the stable value fund to a competing stable/money market vehicle — typically for 90 days. If you have a significant balance in your plan's stable value fund, you may need to execute a two-tranche rollover: move the non-stable-value portion first, wait 90 days, then move the stable value balance. Check your plan's Summary Plan Description (SPD) or call the administrator to confirm.
Common plans with this restriction: Transamerica, Nationwide Fixed Account Plus, Voya Fixed Plus, Principal Fixed Income, John Hancock Stable Value, Empower Stable Value, OneAmerica GIA.
9. ☐ Pending employer contributions check
Annual profit-sharing contributions, annual match true-ups, and end-of-year contributions often aren't deposited until weeks or months after they're earned. If you leave shortly after a year-end, your account may not yet reflect the final employer contribution. Ask the plan administrator whether any contribution is pending before you initiate — otherwise you may roll less than you're entitled to and need a separate rollover of the final deposit later.
10. ☐ Medallion Signature Guarantee / spousal consent check
Some plans require a Medallion Signature Guarantee on the distribution form (available at banks and credit unions — not a notary). Plans covered by ERISA also require spousal consent if you're married and rolling to a non-IRA destination or designating a non-spouse beneficiary. Confirm these requirements upfront so you're not surprised when paperwork comes back rejected.
Phase 3 — Execution mechanics
11. ☐ Request a DIRECT rollover — not an indirect rollover
Always request a direct rollover (also called a trustee-to-trustee transfer). In a direct rollover, the check is payable to the receiving institution "FBO [Your Name]" — no money touches your hands, no mandatory 20% federal withholding, no 60-day clock.5
In an indirect rollover, the check is payable to you. Your employer withholds 20% and sends it to the IRS. You have 60 days to deposit the full original amount — including the 20% you no longer have — into the new account. Most people cannot make up the 20%, resulting in a partial taxable distribution. Direct rollovers are unlimited in frequency; always use them.

12. ☐ If rolling to a Roth IRA: calculate the tax cost first
Rolling a pre-tax 401(k) directly to a Roth IRA is a taxable conversion — every dollar is ordinary income in the year of the rollover. At $250,000 converted in a year where you also have salary income, you can easily push into the 32–37% federal bracket. Use the interactive calculator to model your 2026 bracket impact before initiating a Roth rollover.
Also check the IRMAA cliff: if you're 63 or older, a large conversion in 2026 affects your Medicare Part B and D premiums in 2028 (two-year IRMAA lookback). The first tier starts at $109,000 MAGI for single filers and $218,000 for married filing jointly in 2026.6

13. ☐ Note your plan type — different providers have different timelines
Most direct rollovers complete in 1–3 weeks. But several provider types are slower:
- TIAA Traditional annuity: lump-sum rollover in under 120 days is subject to a 2.5% surrender charge. The alternative is a 9-year Transfer Payout Annuity. Do not initiate casually.
- Insurance-company group annuity plans (Transamerica, Equitable/AXA, Corebridge/VALIC): may have surrender charges on older contracts — confirm before rolling.
- Small employer plans with employer-as-TPA (Paychex, ADP small plans): approval must go through the employer, adding 2–6 weeks.
- Fidelity-to-Fidelity internal transfers: can complete in 3–7 business days.

14. ☐ If indirect rollover: track the 60-day window and once-per-year limit
If you receive a distribution check payable to you (an indirect rollover), you have exactly 60 days from the date of receipt to deposit the full original amount into an IRA or qualified plan.5 Beyond 60 days, the distribution is taxable — you can request a waiver only if you meet qualifying hardship criteria under Rev. Proc. 2016-47.
Additionally, the IRS allows only one indirect IRA-to-IRA rollover per 12-month period across all your IRAs combined (Bobrow v. Commissioner).7 If you've done another indirect IRA rollover in the past 12 months, a second one is a prohibited transaction — the distribution becomes fully taxable plus a 6% excess contribution penalty applies to the redeposit. Direct rollovers (trustee-to-trustee) are not subject to this once-per-year rule.
15. ☐ If rolling a Roth 401(k): confirm the split rollover mechanics
Roth 401(k) accounts contain two types of money: your employee Roth deferrals, and the employer contributions (which are always pre-tax, even in a Roth 401(k)). Rolling the entire account to a Roth IRA creates a problem — the employer's pre-tax portion must go to a traditional IRA. Failing to split the rollover can result in a taxable Roth conversion on the employer match portion. Confirm with your plan administrator how they'll handle the split before initiating.

Phase 4 — Post-completion checklist
Three things to do after funds arrive at the new custodian.
Post-1: ☐ Report the 1099-R correctly on your tax return
Your old plan will send a Form 1099-R showing the amount distributed. For a direct rollover to a traditional IRA, the distribution code is G (non-taxable rollover). For Roth-to-Roth, it's H. Do not ignore the form or assume your tax software handles it automatically.
On Form 1040: if it's an IRA rollover, use Lines 4a (total distribution) and 4b ($0 taxable). If it's a pension/401(k)-to-IRA rollover, Lines 5a and 5b. Many people accidentally report the full amount as taxable income, resulting in a CP2000 notice and a bill that takes months to resolve.

Post-2: ☐ Update beneficiary designations at the new custodian
Beneficiary designations do not transfer with the rollover. If you had a non-spouse primary beneficiary on your old 401(k), your new IRA has no beneficiary until you add one. Estates are poor beneficiaries because they eliminate the stretch IRA option entirely. Log in to your new IRA and complete beneficiary designations before you forget.
Post-3: ☐ Invest the funds — they arrive as cash
Most custodians park incoming rollover funds in a money market settlement fund pending your investment instructions. This is fine for a few days, but leaving $500,000 in a settlement fund earning 4–5% APY when your target allocation calls for equity exposure costs real money over time. Log in, confirm the funds arrived, and allocate to your target portfolio.
Three real-dollar scenarios
Scenario 1 — Job change at 56, Rule of 55 applies
Marcus is 56, leaves a large employer, and has $680,000 in his 401(k). He won't start a new job for 18 months. He needs $45,000/year in living expenses during the gap.
He runs through the checklist: no employer stock (NUA = N/A), he doesn't use Backdoor Roth ($680K in pre-tax 401k vs. no IRA), no outstanding loan, fully vested.
Phase 1 flag: Rule of 55 applies — he's 56 and just separated. If he rolls to an IRA, he loses penalty-free access. He'd need SEPP payments — a rigid schedule he can't adjust without triggering the modification trap.
Decision: Marcus keeps $90,000 in the old 401(k) for two years of bridge income ($45K × 2), takes annual distributions directly from the plan, then rolls the remaining $590,000 to a Fidelity IRA at 58½. He calls the plan administrator to confirm it allows ongoing distribution flexibility rather than lump-sum only.
Rule of 55 preservation saved him $9,000 in 10% penalties ($45,000 × 10% × 2 years) — just from Phase 1 of the checklist.
Scenario 2 — Tech worker protecting Backdoor Roth, no employer stock
Priya is 38, leaves a FAANG company for a startup. Her old Fidelity NetBenefits 401(k) has $290,000 (all pre-tax). She currently has $0 in IRAs. Her household income is $385,000 MFJ — Backdoor Roth is essential for her retirement savings.
Phase 1 checklist: Rule of 55? No (under 55). NUA? No employer stock in a FAANG plan. Backdoor Roth? Yes — this is a critical flag.
If she rolls $290,000 to a traditional IRA, her next $7,000 Backdoor Roth contribution is 97.7% taxable — $6,839 in ordinary income, roughly $1,640/year at 24% federal. Across 20+ years, this error compounds into $50,000+ in unnecessary taxes.
Her new startup's 401(k) (through Guideline) accepts incoming rollovers. She rolls the $290,000 from the old plan directly to the new employer's plan. Traditional IRA stays at $0. Backdoor Roth continues cleanly.
Scenario 3 — Retiree managing IRMAA cliff
Linda is 63, just retired, and has $1.4M in a Principal 401(k) plus $85,000 in an existing traditional IRA. No employer stock. No loan. No Backdoor Roth concern — she's no longer working.
Phase 1 flags: Rule of 55 no longer relevant (she's 63 and retired, 59½ already passed). Checks out on all six items.
Phase 2: she checks her Principal balance — 35% is in the Principal Stable Value Separate Account. This has an equity wash restriction. She plans a two-tranche rollover: the equity and bond portion ($910,000) in month 1, the stable value portion ($490,000) in month 4 after the 90-day hold.
Phase 3: she calculates Roth conversion impact. Her current MAGI is ~$22,000 (just investment income). Rolling $910,000 all at once to a Roth IRA would push her far into the 37% bracket. Instead she plans a $150,000/year partial conversion over 5–6 years — staying just below the $218,000 IRMAA Tier 1 threshold ($109,000 single, $218,000 MFJ). This means she converts at 22–24% federal instead of 37%, and avoids the $81.20/month Medicare surcharge.
She rolls the full balance to a traditional rollover IRA and begins systematic Roth conversions in January.
