401k Rollover Guide 2026: Direct vs Indirect vs Roth

The four options, at a glance

Every 401(k) rollover decision boils down to one of four paths. Three of them keep your money in a tax-advantaged account; one takes it out of the retirement system entirely.

• Direct rollover to a Traditional IRA (or new employer plan). Your old plan sends the money straight to the new account — you never touch it. No tax, no penalty, regardless of your age. This is the default “safe” move for most people.
• Direct rollover/conversion to a Roth IRA. Also a direct transfer, but because you're moving pre-tax money into an after-tax account, the entire converted balance is taxed as ordinary income in the year you convert — federal and state. There's no 10% early-withdrawal penalty on the conversion itself, no matter your age, but you do owe income tax on the whole amount, typically due the following April.
• Indirect (60-day) rollover. The plan cuts you a check instead of sending it directly — and by law, it must withhold 20% for federal taxes before doing so. You then have 60 days to deposit money into a new retirement account. To avoid tax and penalty on the whole amount, you have to deposit the FULL original balance, not just what you received — meaning you need to come up with the 20% that was withheld from other funds. Miss that, and the shortfall counts as a taxable distribution, plus a 10% penalty if you're under 59½.
• Cashing out. You take the money as ordinary income, taxed federal + state, plus a 10% early-withdrawal penalty if you're under 59½ — with one notable exception (the “Rule of 55,” below). This is almost always the most expensive option and should be a last resort.

The DueMATH 401(k) Rollover Calculator walks through the tax math for each of these based on your balance, age, tax bracket, and state.

Why the 20% withholding on indirect rollovers trips people up

This is the single most common — and most expensive — mistake in 401(k) rollovers. Say you have $50,000 in an old 401(k) and request an indirect rollover. The plan is legally required to withhold 20% ($10,000) and sends you a check for $40,000. If you deposit that $40,000 into an IRA within 60 days and think you're done, you've actually made a costly error: the IRS treats the $10,000 that never got redeposited as a taxable distribution, and if you're under 59½, it also owes a 10% penalty on top.

To roll over the full $50,000 tax-free, you'd need to deposit the entire $50,000 within 60 days — using $10,000 of your own other money to make up for what was withheld. The withheld $10,000 isn't lost; it comes back as a credit against your tax bill when you file. But most people don't have $10,000 in spare cash sitting around to front, which is exactly why financial advisors near-universally recommend a direct rollover instead — it simply skips this entire problem, because no withholding ever happens.

The Rule of 55

There's one meaningful exception to the 10% early-withdrawal penalty on a 401(k) cash-out: if you separate from your employer (quit, get laid off, or retire) in or after the calendar year you turn 55, you can take distributions from THAT employer's 401(k) plan without the 10% penalty. You still owe ordinary income tax on what you withdraw — this exception only waives the penalty, not the tax.

Two important limits: this only applies to the 401(k) from the job you just left, not old 401(k)s from previous employers or IRAs, and it only applies if you're still 55 or older when you actually take the distribution. Rolling that 401(k) into an IRA before withdrawing would forfeit this exception entirely — IRAs don't get the Rule of 55.

The Roth conversion trap: the 5-year clock

A detail that's easy to miss: converting to a Roth IRA starts its own separate 5-year clock for the converted amount — distinct from the 5-year clock on the Roth account itself. If you withdraw the converted principal within 5 years of the conversion AND you're under 59½, a 10% “recapture” penalty can apply to that converted amount, even though the conversion itself triggered no penalty when you made it. This mostly matters for people doing a Roth conversion specifically to access the money soon after (a “backdoor” access strategy) — if you're converting for genuine long-term retirement savings, it's less likely to bite, but it's worth knowing the clock exists before you plan around it.

Traditional or Roth — which is actually better?

There's no universal answer — it depends on whether you expect to be in a higher or lower tax bracket when you eventually withdraw the money in retirement. Broadly:

• Traditional IRA (direct rollover) defers tax until retirement. This tends to favor people who expect to be in a LOWER tax bracket in retirement than they are now — a common situation, since income (and often the tax bracket that comes with it) tends to drop after you stop working.
• Roth conversion means paying tax now, at your current rate, in exchange for completely tax-free withdrawals later — including on any growth. This tends to favor people who expect to be in a HIGHER bracket later, are early in their career with room in a lower bracket right now, or who want to avoid Required Minimum Distributions (Roth IRAs don't have them for the original owner).

For a large balance, this is genuinely worth running past a financial advisor or CPA — the conversion tax bill is due in full the year you convert, and getting the timing wrong (say, converting in a high-income year) can be an expensive mistake.
