401k Rollover Rules 2026
Expert guide: 401k Rollover Rules 2026 – IRS Rules and Deadlines.
Key 401k rollover rules: 60-day deadline for indirect rollovers; one indirect rollover per 12-month period; 20% mandatory withholding on indirect rollovers (must deposit 100% including withheld amount); no limit on rollover amount; and rollover must come from a qualifying retirement account (401k, 403b, 457b, SEP IRA, SIMPLE IRA).
401k Rollover Checklist
- Open your new IRA first before starting the rollover process
- Request a direct rollover — never have the check made out to you
- Confirm it's going to the right account — Traditional 401k → Traditional IRA (tax-free)
- Invest the funds — rolled-over money often lands in cash — invest in ETFs promptly
- Update your beneficiaries on the new IRA account
Frequently Asked Questions
Direct rollovers typically take 2–4 weeks: 1–3 days to open the new IRA, 5–10 business days for the old plan to process, 1–5 business days for the receiving institution to credit the funds, then 1–3 days to invest. Some plans take longer — follow up if it takes over 4 weeks.
Only if the old plan has excellent investment options (Vanguard institutional funds) or very low costs. Most employer 401ks have higher expense ratios than IRAs at Fidelity or Vanguard. Rolling to an IRA gives you broader investment options, potentially lower costs, and one fewer account to track. Exceptions: if you might need the funds before 59½ (401k has penalty-free access at 55 in some cases).
The Rules That Matter Most
- Direct rollovers carry no deadline — you can leave funds in an old 401(k) indefinitely (if your balance is over $7,000) or roll over whenever you choose — there's no time pressure on a direct trustee-to-trustee transfer.
- Indirect rollovers have a strict 60-day deadline — starting from the day you actually receive the distribution, not the day you requested it — missing this window turns the shortfall into a taxable distribution.
- Small balances may be auto-rolled by your old plan — under SECURE 2.0, balances under $7,000 left unattended may be automatically moved to an IRA by your former employer's plan if you don't take action.
- RMD amounts can't be rolled over — if you're at Required Minimum Distribution age, your RMD for the year must be taken first — RMD amounts specifically are ineligible for rollover into another account.
State Tax Withholding Complications
Some states (California, Vermont, and Maine among them) impose mandatory state income tax withholding on distributions, in addition to the federal 20% — states with no income tax (Texas, Florida, Nevada, and similar) don't withhold anything. Checking your specific state's rules before requesting any distribution avoids an unexpected additional withholding surprise.
Reporting on Your Tax Return
A properly executed direct rollover is reported to the IRS on Form 1099-R, coded to indicate a non-taxable rollover — you report it on your tax return, but it doesn't increase your taxable income. This is different from an indirect rollover where any portion not redeposited within 60 days becomes genuinely taxable income for that year.
