Key Takeaway

Avoid taxes on 401k rollover: use a direct rollover (institution-to-institution). If you receive the funds directly (indirect rollover), you have 60 days to deposit 100% of the distribution (including 20% withheld) into an IRA to avoid taxes. Rolling traditional 401k to Roth IRA triggers income tax. Rolling to Traditional IRA is tax-free.

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

How long does a 401k rollover take?

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.

Should I leave my 401k at my old employer?

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).

When a Rollover Is Tax-Free

  • Traditional 401(k) → Traditional IRA (direct) — generally tax-free — pre-tax money moving between pre-tax accounts.
  • Roth 401(k) → Roth IRA (direct) — generally not taxable when handled correctly — after-tax money moving between after-tax accounts.

When a Rollover Triggers Taxes

  • Traditional 401(k) → Roth IRA — generally taxable in the conversion year — you're moving pre-tax money into an account requiring after-tax dollars, so you owe ordinary income tax on the full converted amount.
  • Indirect rollover with a missed deadline or shortfall — any amount not redeposited within 60 days becomes a taxable distribution, plus a possible 10% early withdrawal penalty if you're under 59½.

The 10% Early Withdrawal Penalty

This penalty applies specifically to amounts that become taxable distributions before age 59½ — it does NOT apply to amounts actually rolled over successfully, whether via direct rollover or a properly completed indirect rollover within the 60-day window. The penalty only bites when a rollover goes wrong, not on a correctly executed one.

Fees to Watch For Separately From Taxes

The IRS itself doesn't charge a rollover fee, but your old plan, new custodian, financial advisor, or investment platform might — account closing fees, wire fees, and setup fees are all possible depending on the institutions involved. Asking for a written fee schedule before initiating the rollover avoids an unexpected charge showing up after the fact.
