How to Avoid Taxes on 401(k): Rollovers, NUA, and Roth Conversions

The cleanest way to avoid taxes on 401(k) withdrawals is not to take a withdrawal at all: move the money through a direct rollover into another qualified retirement account or IRA and nothing is taxed. Beyond that, several strategies can shrink or eliminate the tax on money you actually pull out, including 401(k) loans, net unrealized appreciation on employer stock, the Rule of 55, substantially equal periodic payments, and well-timed Roth conversions. Every dollar in a traditional 401(k) is pre-tax money the IRS expects to collect on eventually, so the real goal is controlling when and how you pay.¹

Move Money With a Direct Rollover

A direct rollover sends your 401(k) balance straight from your current plan to another qualified plan or an IRA without the funds ever passing through your hands. Because the money never becomes a distribution, no tax is due and nothing is withheld.²

Ask your current plan administrator for a distribution election form. You’ll need the receiving custodian’s legal name, mailing address or wire details, and the destination account number. The check gets made out to the new custodian “For Benefit Of” your name, which signals to everyone involved that the money is staying inside a retirement account. Electronic transfers do the same job faster and keep the balance invested along the way.

Paper checks often take 30 days or longer to arrive and post; wires are quicker.² Once the transfer settles, you’ll get a Form 1099-R documenting the rollover for your tax return. Nothing is owed.

Watch the 60-Day Clock on Indirect Rollovers

If the check gets sent to you instead of the new custodian, you’re in an indirect rollover and the rules change fast. You have 60 days to deposit the full distribution amount into a qualified retirement account, or the whole thing becomes taxable income.²

Worse, your plan administrator is required to withhold 20% for federal taxes before cutting you the check.³ A $100,000 balance shows up as an $80,000 check. To make the rollover fully tax-free, you still have to deposit the full $100,000 into the new account within 60 days, which means covering that $20,000 gap from your own pocket. You get the withheld money back when you file, but only if you rolled the full amount. Anything short is treated as a taxable distribution, plus a 10% penalty if you’re under 59½.

The IRS can waive the 60-day deadline for circumstances beyond your control, but waivers are not guaranteed. A direct rollover sidesteps all of this.

Borrow From Your 401(k) Instead of Withdrawing

A 401(k) loan gives you access to the money without triggering a taxable event. You can borrow the lesser of $50,000 or half your vested balance, with a minimum borrowing allowance of $10,000.⁴ Repayment goes back into your own account, interest and all.

Loans generally have to be repaid within five years (longer if the loan bought your primary residence), with payments at least quarterly in roughly equal amounts.⁴ Stay on schedule and the loan never touches your tax return.

The risk shows up if you leave the job. The plan can reduce your remaining balance by the unpaid loan, a “plan loan offset,” and that offset is normally treated as a taxable distribution. When the offset happens because you separated from service or the plan terminated, you have until the due date of your tax return, including extensions, to roll the offset amount into another retirement account and avoid the tax.⁵ Miss that window and you owe income tax on the unpaid balance, plus the 10% early-withdrawal penalty if you’re under 59½.

Use Net Unrealized Appreciation on Company Stock

If your 401(k) holds employer stock that has grown substantially, net unrealized appreciation (NUA) can convert what would be ordinary income into long-term capital gains. Rather than rolling the stock into an IRA, you distribute the shares themselves into a taxable brokerage account.⁶

At the moment of transfer, you pay ordinary income tax only on the original cost basis of the stock, the value when it first landed in the plan. The appreciation above that basis stays untaxed until you sell, and at sale it’s taxed at long-term capital gains rates: 0%, 15%, or 20% for 2026, depending on income.⁷ Ordinary income rates run from 10% to 37%, so the savings on highly appreciated stock can be substantial.

NUA has strict requirements. The distribution must be a lump-sum distribution, meaning you empty the entire plan balance in one tax year, and you must have hit a qualifying triggering event: separation from service, age 59½, total disability (for self-employed individuals), or death. Non-stock assets in the plan can roll into an IRA to avoid immediate taxation on those portions. Ask your plan administrator for the cost basis figures early; you’ll need them to file correctly.

Access Money Before 59½ Without the Penalty

Pulling from a 401(k) before 59½ usually triggers a 10% early distribution penalty on top of ordinary income tax.⁸ Two exceptions remove the penalty, though the income tax still applies.

The Rule of 55

Leave your job during or after the calendar year you turn 55, and you can take penalty-free withdrawals from that employer’s 401(k).⁴ The exception is narrow: it only covers the plan tied to the employer you separated from, not old 401(k)s from previous jobs or IRAs. Qualified public safety employees get the same treatment at age 50. If you’re planning ahead, rolling older 401(k) balances into your current plan before you leave lets the full amount qualify.

The separation has to happen in or after the year you turn 55. Quitting at 54 and waiting until the next year to withdraw doesn’t work.

Substantially Equal Periodic Payments

Substantially equal periodic payments (SEPP, or the “72(t) method”) let you take regular withdrawals at any age without the 10% penalty, as long as you follow a rigid schedule based on your life expectancy. For a 401(k), you must separate from the employer sponsoring the plan before payments can start.⁹

Once started, payments must continue unchanged until the later of five years from the first payment or the date you turn 59½. Changing the amount, stopping early, or adding money to the account before that date triggers a recapture tax: the 10% penalty gets applied retroactively to every distribution you took, plus interest.⁹ SEPP suits people who need steady income well before 59½ and can commit to a fixed annual withdrawal for years.

Convert to a Roth Account to Zero Out Future Taxes

A Roth conversion inverts the usual 401(k) equation. You pay income tax now on the amount you convert, and every dollar of future growth and every qualified withdrawal comes out tax-free. You can convert by rolling a traditional 401(k) directly into a Roth IRA, or, if your plan allows it, by moving pre-tax dollars into a designated Roth account inside the same plan.¹⁰

The converted amount counts as ordinary income in the year of conversion, so the strategy pays off most when your income is temporarily low: a gap between jobs, early retirement before Social Security begins, or a year with unusually large deductions. Converting a slice at a time over several years keeps you from vaulting into a higher bracket. There’s no income limit and no cap on the amount converted.

Once the money is in a Roth account, qualified distributions are completely excluded from gross income. A distribution qualifies if you’ve held the Roth account for at least five tax years and you’re 59½ or older, disabled, or the payment is made to a beneficiary after your death.¹¹ Roth accounts are also exempt from required minimum distributions during the owner’s lifetime, so the balance can keep growing tax-free indefinitely.

Reduce or Redirect Required Minimum Distributions

You can’t defer traditional 401(k) taxes forever. Starting at age 73, the IRS requires annual withdrawals known as required minimum distributions (RMDs). If you’re still working for the employer sponsoring the plan, most plans let you delay RMDs until you actually retire.¹² Under the SECURE 2.0 Act, the RMD age rises to 75 for individuals born in 1960 or later, effective in 2033.

Your first RMD is due by April 1 of the year after you turn 73 (or after you retire, if later and your plan permits the delay). Every RMD after that is due December 31. Pushing the first one to April 1 means taking two RMDs in the same calendar year, which can shove you into a higher bracket.

Each year’s amount is your prior year-end balance divided by a life expectancy factor from the IRS Uniform Lifetime Table.¹² Missing an RMD or withdrawing too little triggers a 25% excise tax on the shortfall, dropping to 10% if you correct it within two years.¹³

Two moves shrink the tax bite. Converting portions of your traditional 401(k) to a Roth in lower-income years before 73 reduces the balance subject to RMDs later. And once you reach age 70½, qualified charitable distributions (QCDs) let you send up to $105,000 per year directly to charity, satisfying your RMD without adding a dollar to taxable income. QCDs can’t be made directly from a 401(k), so you’d first need to roll the balance into an IRA.

What Doesn’t Avoid Taxes

Hardship withdrawals are commonly misunderstood on this point. A hardship withdrawal lets you access 401(k) money for immediate and heavy financial needs like medical bills, funeral costs, tuition, or preventing eviction, but it does not avoid the tax. The amount is taxed as ordinary income, and the 10% early withdrawal penalty generally applies if you’re under 59½.¹⁴ Unlike a 401(k) loan, a hardship distribution can’t be repaid to the plan. If you have a choice, a loan almost always costs less than a hardship withdrawal.

Don’t Forget State Income Tax

Federal treatment is only half the picture. Most states tax 401(k) distributions as ordinary income, but the rules vary widely. Some states have no income tax; others exclude some or all retirement income, often tied to age thresholds like 59½ or 65. State rates on retirement withdrawals range from 0% to more than 13% in the highest-tax states. If you have flexibility about where to live in retirement, checking your state’s treatment of retirement income before you start taking money out can meaningfully reduce your total tax bill. Rules differ enough that checking with your state’s tax agency or a local tax professional is worth the time.
