A 401k rollover to an IRA is one of the most important financial moves you make when changing jobs. Done correctly (direct rollover), it is completely tax-free. Done incorrectly (indirect rollover), 20% is withheld for taxes and you have 60 days to redeposit the full amount — including the withheld portion — to avoid taxes and penalties.
Direct Rollover vs. Indirect Rollover — Always Choose Direct
Direct rollover: Your old 401k plan sends the money directly to your new IRA custodian (Fidelity, Vanguard, etc.). Zero taxes withheld, zero risk of penalties, no 60-day deadline. This is always the correct approach.
Indirect rollover (cash out): Your old plan sends you a check with 20% withheld for federal taxes. You have 60 days to redeposit the full original amount (including the 20% withheld) into an IRA. If you only deposit 80%, the withheld 20% is treated as a distribution — subject to income tax plus 10% early withdrawal penalty if under 59.5. Never accept an indirect rollover unless you have no choice.
How to initiate a direct rollover: Contact your new IRA custodian first — they walk you through the process and handle most of the paperwork. Then contact your old 401k plan administrator with the rollover instructions from your new custodian.
Best 401k Rollover Destinations in 2026
Fidelity: The top overall destination for most investors. Zero-fee IRA accounts, four zero-expense-ratio index funds (FZROX, FZILX, FZIPX, FZDXX), fractional shares, and the highest-rated customer service in annual investor surveys (J.D. Power 2025). Rollover process is well-documented with phone support available. Best for: hands-off investors who want low costs and good support.

How I’d Invest a 401k Rollover Today
Vanguard: Created the index fund and still offers the lowest expense ratios on many funds (Admiral Shares as low as 0.03%). No account fees for accounts over $1,000 in Vanguard funds. Interface is dated compared to Fidelity but improving. Best for: Vanguard loyalists and investors who want to hold Vanguard funds directly (vs. holding them at Fidelity, which is also possible).
Schwab: No account fees, competitive index fund expense ratios (Schwab Total Market at 0.03%), excellent mobile app, and strong financial planning tools. Integrated banking (Schwab Bank checking account) simplifies cash management. Best for: investors who want combined brokerage and banking with competitive fund costs.
Betterment or Wealthfront (robo-advisor rollover): If you want automated management of your IRA rather than DIY, both accept IRA rollovers. Betterment charges 0.25% annually for automated management; Wealthfront 0.25% with $500 minimum. Appropriate if you want hands-off allocation rather than selecting individual funds.
Rollover vs. Leave in Old Plan vs. Move to New Employer Plan
Roll to IRA: More investment options, potentially lower costs, consolidated into accounts you control. Generally the best choice for most people.
Leave in old 401k: Only makes sense if the plan has exceptional institutional funds unavailable elsewhere (some government plans, large employers). Not appropriate as a long-term solution — accounts at former employers are easily forgotten.
Roll to new employer 401k: Makes sense if new plan has matching contributions available immediately, or if you plan to retire and want to avoid required minimum distributions (RMDs) at 73 — 401k assets at your current employer when you turn 73 may avoid RMDs under the "still working" exception.
Cash out: Worst option for anyone under 59.5 — 10% penalty plus ordinary income taxes. For $50,000 in a 401k, cashing out could cost $15,000-$20,000 in taxes and penalties depending on your tax bracket.
Roth Conversion at Rollover
When rolling over a traditional (pre-tax) 401k, you have the option to convert to a Roth IRA. This triggers ordinary income tax on the converted amount in the year of conversion, but all future growth is tax-free. Roth conversions make sense when: you are in a lower tax bracket than you expect to be in retirement; you have a down income year; or you want to pass tax-free assets to heirs. Consult a tax professional — the math depends heavily on your current and expected future tax rates.
