What a one-time payment is and when you might take one
A one-time payment from a retirement account is a single withdrawal of money instead of receiving it in regular installments over time. You might take one when you leave a job, reach retirement age, or need a lump sum for a specific reason. The tax treatment and rules depend on which account type you're withdrawing from and your age when you take it.
One-time payments are different from periodic withdrawals or structured distributions. With a periodic withdrawal, you take money out on a schedule you choose — monthly, quarterly, or annually. With a one-time payment, you take the entire amount (or a large portion of it) in a single transaction. The account may still exist afterward, but you've removed the funds you wanted in one go.
Whether a one-time payment makes sense depends on your tax bracket that year, whether you'll face penalties, and whether you need the money now or can let it grow. Taking a large sum can push you into a higher tax bracket, meaning you'll owe more in taxes on that withdrawal than you would if you spread it across multiple years.
Key Takeaways
- One-time payments are taxed as ordinary income in the year you withdraw them, which can increase your tax bill significantly if the amount is large.
- If you withdraw before age 59½ from most retirement accounts, you typically owe a 10% early withdrawal penalty on top of income tax, unless an exception applies.
- Some accounts, like traditional IRAs and 401(k)s, allow you to take a one-time payment of your entire balance; others have restrictions on how much you can withdraw at once.
- Roth IRAs let you withdraw contributions (the money you put in) at any time without tax or penalty, but earnings withdrawals before 59½ usually trigger both tax and penalty.
- If you receive a one-time payment from an employer plan when you leave a job, you can roll it into an IRA within 60 days to avoid when ready taxation.
One-time payments from traditional IRAs and SEP IRAs
A traditional IRA allows you to withdraw any amount at any time. There is no rule saying you must take periodic distributions or that you cannot take a lump sum. However, the entire withdrawal is taxed as ordinary income in the year you take it. If you withdraw $50,000 in a single year, that $50,000 is added to your other income for tax purposes, and you pay tax at your marginal rate.
If you are under age 59½, you also owe a 10% early withdrawal penalty on the amount withdrawn, unless an exception applies. Common exceptions include withdrawals for a first home purchase (up to $10,000 lifetime), medical expenses above 7.5% of your adjusted gross income, health insurance premiums while unemployed, and substantially equal periodic payments (a specific calculation that locks you into regular withdrawals for at least five years or until age 59½, whichever is later).
A SEP IRA (Simplified Employee Pension) follows the same rules as a traditional IRA for withdrawals. You can take a one-time payment, it is taxed as ordinary income, and the 10% early withdrawal penalty applies if you are under 59½ unless an exception fits your situation.
One-time payments from 401(k)s and 403(b)s
When you leave an employer, you can usually request a one-time payment of your entire 401(k) or 403(b) balance. This is sometimes called a lump-sum distribution. The entire amount is taxed as ordinary income in the year you receive it. If the balance is large, this can significantly increase your tax bill and push you into a higher tax bracket.
If you are under age 59½, the 10% early withdrawal penalty applies to the taxable portion unless you may have access to for an exception. One important option: if you receive a lump-sum distribution from an employer plan, you can roll it over into a traditional IRA within 60 days. This move avoids when ready taxation and penalties, and lets the money continue to grow tax-deferred. Your employer's plan administrator will provide instructions on how to initiate a rollover.
Some employer plans also offer a direct rollover, where the plan sends the money straight to an IRA or another employer plan without it passing through your hands. A direct rollover is simpler and avoids the 60-day important date risk. If the plan does not offer a direct rollover and you receive the check yourself, you must deposit it into an IRA within 60 days or the full amount becomes taxable and subject to the early withdrawal penalty.
One-time payments from Roth IRAs
A Roth IRA distinguishes between contributions (the money you deposited) and earnings (the growth on that money). You can withdraw your contributions at any time, in any amount, without tax or penalty — even before age 59½. This is one of the key advantages of a Roth IRA.
Earnings, however, follow different rules. If you withdraw earnings before age 59½ and before the account has been open for at least five tax years, you owe income tax on the earnings plus a 10% penalty. If the account has been open for five years or more and you are age 59½ or older, you can withdraw earnings tax-free and penalty-free. If you are under 59½ but the five-year rule is met, you still owe tax on the earnings but not the penalty.
When you take a one-time payment from a Roth IRA, the IRS treats withdrawals as coming from contributions first, then earnings. So if you have $100,000 in the account and $60,000 of that is contributions, you can withdraw up to $60,000 with no tax or penalty. Anything above that is treated as an earnings withdrawal and subject to the rules above.
One-time payments from straightforward IRAs
A straightforward IRA is offered by small employers and allows both employee and employer contributions. Withdrawals are taxed as ordinary income. If you withdraw before age 59½, the early withdrawal penalty is normally 10%, but there is an important exception: if you withdraw within the first two years of opening the account, the penalty is 25% instead of 10%.
This higher penalty applies only during the first two years. After that, the standard 10% penalty applies if you are under 59½. The same exceptions that explore to traditional IRAs — first-home purchase, medical expenses, and others — also explore to straightforward IRAs and can eliminate the penalty if your situation fits.
Tax withholding on one-time payments
When you take a one-time payment from a retirement account, your plan administrator or financial institution may withhold taxes automatically. For employer plans like 401(k)s and 403(b)s, federal tax withholding is usually 20% of the distribution if you do not do a direct rollover. For IRAs, the withholding rate is typically 10% unless you request a different amount.
Withholding is not the same as your actual tax bill. If you owe more than what was withheld, you will owe the difference when you file your tax return. If more was withheld than you owe, you will receive a refund. To avoid surprises, consider consulting a tax professional before taking a large one-time payment so you understand your total tax liability for that year.

Frequently Asked Questions
Can I take a one-time payment from my 401(k) while still working?
Most employer 401(k) plans do not allow withdrawals while you are still employed, with limited exceptions like hardship withdrawals or loans. Once you leave the job, you can request a lump-sum distribution. Some plans offer in-service distributions or loans, but these vary by plan. Check your plan documents or ask your employer's benefits administrator what options are available to you.
What happens if I take a one-time payment and it pushes me into a higher tax bracket?
Your one-time withdrawal is added to your other income for the year, and you pay tax at the combined total. If the withdrawal is large enough to move you into a higher bracket, you pay the higher rate on the portion of income that falls in that bracket. This is why some people spread withdrawals across multiple years — to stay in a lower bracket. A tax professional can model different scenarios for you.
Is a rollover the same as a one-time payment?
No. A rollover is what you do with a one-time payment to avoid taxes. You receive a lump-sum distribution from your employer plan, then deposit it into an IRA within 60 days. The rollover itself is not taxable; only money you keep outside the IRA is taxed. A direct rollover (plan to IRA) is simpler because the money never passes through your hands.
Can I take a one-time payment from a Roth IRA without paying taxes?
Yes, if you withdraw only your contributions. You can withdraw the money you personally deposited at any time, tax-free and penalty-free. Withdrawals of earnings are taxed and penalized if you are under 59½ and the account has not been open for five years. The IRS treats your withdrawal as coming from contributions first, so you can withdraw up to your total contributions without tax consequences.
What is the 60-day rollover important date, and what happens if I miss it?
If you receive a lump-sum distribution from an employer plan (not a direct rollover), you have 60 calendar days to deposit it into an IRA. If you miss the important date, the entire amount becomes taxable income for that year, and you owe the 10% early withdrawal penalty if you are under 59½. The 60 days is strict — there is no extension. A direct rollover avoids this risk because the plan sends the money directly to the IRA.
