How Much Tax Will I Pay on My 457 Withdrawal?

Money you pull from a traditional governmental 457(b) is taxed as ordinary income at your federal bracket, which runs from 10% to 37% for 2026 depending on your total income for the year. The tax on a 457 withdrawal has one big advantage over a 401(k) or IRA: there’s no 10% early withdrawal penalty on governmental 457(b) money, no matter your age when you take it out.¹ What you actually owe depends on how much you take, when you take it, and what else you earn that year.

How the Withdrawal Stacks on Your Other Income

Every dollar you deferred into a traditional 457(b) becomes taxable in the year you receive it.² The IRS adds the distribution to everything else you earned — wages, interest, Social Security — and runs the combined total through the progressive brackets.

For a single filer in tax year 2026, those brackets are:³

10% up to $12,400
12% from $12,401 to $50,400
22% from $50,401 to $105,700
24% from $105,701 to $201,775
32% from $201,776 to $256,225
35% from $256,226 to $640,600
37% over $640,600

You don’t pay the top rate on every dollar. Say you earn $45,000 in wages and pull $10,000 from your 457(b). Your total taxable income is $55,000 before deductions. The first $12,400 is taxed at 10%, the next slice at 12%, and only the portion above $50,400 — about $4,600 — reaches the 22% bracket. The withdrawal doesn’t carry a single rate. It lands on top of your other income and gets taxed at whatever brackets that top slice occupies.

The layering effect is where planning changes real dollars. A $30,000 withdrawal might cost roughly $3,600 in federal tax if it’s your only income for the year, but closer to $6,600 if you already earn $80,000. Timing a large distribution for a lower-income year — after retirement, before Social Security starts, in a gap year between jobs — cuts the bill.

No 10% Early Withdrawal Penalty

The 10% penalty that hits early withdrawals from 401(k)s, 403(b)s, and IRAs simply does not apply to governmental 457(b) distributions.¹ A government employee who separates at 52 can tap the account immediately, paying ordinary income tax but no penalty. Someone in the same situation with a 401(k) would owe the extra 10% unless a narrow exception applied.

There is one exception inside the 457(b) itself. If you rolled money in from a 401(k), 403(b), or IRA at some point, those dollars keep their old character. Withdraw them before 59½ and the 10% penalty applies to that portion.⁴ Your plan should track the rolled-in balance separately. If you’ve ever moved money into your 457(b) from another plan, ask the administrator to confirm.

The same trap runs in reverse. Rolling a 457(b) into a traditional IRA converts those dollars into IRA money, and IRA rules then govern. Take them out before 59½ and the 10% penalty applies.⁵ For anyone under 59½ who might need the money before traditional retirement age, leaving funds in the 457(b) preserves the penalty-free access that makes the plan valuable.

What Gets Withheld vs. What You Actually Owe

Withholding is a prepayment, not the final tax. The amount your plan pulls off the top depends on the type of distribution.

If you take a lump sum or any distribution that could have been rolled over but you take as cash instead, the plan must withhold 20% for federal taxes, and you can’t opt out.⁶ On a $50,000 distribution, $10,000 goes to the IRS immediately.

Distributions not eligible for rollover, such as required minimum distributions, default to 10% withholding, which you can raise, lower, or zero out using Form W-4R. Periodic payments — monthly or quarterly installments spread over years — are withheld like wages based on the W-4P you file.⁷

None of these rates is your actual tax. If your true rate for the year lands at 12%, the 20% held back comes partly back as a refund. If your total income lifts you into the 24% bracket, you’ll owe more at filing. A big midyear distribution with only 20% withheld can leave a balance due plus an underpayment penalty, so quarterly estimated payments are worth considering when the withdrawal is large relative to your other income.

Roth 457(b) Withdrawals

If your plan offers a Roth option and you contributed on an after-tax basis, those dollars follow different rules. Your original Roth contributions come back tax-free in every case because you already paid tax on them. The earnings are the question.

For the earnings to be tax-free, the distribution has to be qualified: at least five tax years must have passed since January 1 of the year of your first Roth contribution to the plan, and you must be 59½ or older, disabled, or deceased.⁸ Meet both and the whole payout comes out untaxed. Miss either, and the earnings portion is added to your ordinary income at your regular rate.⁹ The plan tracks the contribution-versus-earnings split for you.

State Income Tax

Federal tax isn’t the whole bill. Most states with an income tax treat 457(b) distributions as ordinary income at the state rate. A handful of states have no income tax, and some exempt part of retirement income or give a break to public pension recipients above a certain age. Two retirees taking the same distribution can face state bills that differ by thousands depending on where they live.

Whether your plan withholds state tax automatically varies. Some states require it; others expect you to handle it through quarterly estimates. Check with your state tax agency before your first distribution to avoid an underpayment penalty.

Required Minimum Distributions and the Penalty for Missing One

You can’t leave the money in forever. Once you hit the applicable age, the IRS requires you to withdraw a minimum each year:

Age 73 if you were born between 1951 and 1959 (you reach 73 before 2033)¹⁰
Age 75 if you were born in 1960 or later¹¹

Your first RMD is due by April 1 of the year after you reach the age. Every RMD after that is due by December 31. If you’re still working for the employer sponsoring the plan, you may be able to delay RMDs from that plan until you actually retire.

Missing an RMD is expensive. The IRS charges a 25% excise tax on the amount you should have taken, which drops to 10% if you correct the shortfall within two years.¹⁰ The RMD is still ordinary income when you finally take it, and doubling up a missed RMD with the current year’s RMD can push a big slice of income into a higher bracket.

Non-Governmental 457(b) Plans Work Differently

Everything above applies to governmental 457(b) plans offered by state and local governments, public universities, and similar employers. Non-governmental 457(b) plans, offered by tax-exempt organizations like some hospitals and charities, have different rules. Funds remain the employer’s property until distributed, sit in an unfunded arrangement exposed to the employer’s creditors, and cannot be rolled into an IRA or another plan.¹² Distributions can become taxable when the funds are paid or “made available” to you.² If your plan is non-governmental, the payout terms in your plan document control the timing and tax treatment, and professional advice before a payout is worth its cost.

Reporting the Withdrawal at Tax Time

Your plan sends Form 1099-R by January 31 of the year after your distribution.¹³ Box 1 shows the total distributed, Box 2a the taxable portion (usually identical for a traditional 457(b)), Box 4 the federal tax withheld, and Box 14 any state withholding.

On Form 1040, the total distribution goes on line 5a and the taxable amount on line 5b.¹⁴ The withholding from Box 4 goes in the payments section so you get credit for taxes already sent in. If withholding fell short of your actual liability, you’ll owe the balance; if it exceeded, you’ll get a refund.
