Pension Buyout Tax Rules: Rollovers, Withholding, and Penalties
6 min read · Updated 2026-08-26
The tax rule that matters most: a lump sum paid directly to you triggers mandatory 20 percent federal income tax withholding and, if you are under 59 and a half, usually a 10 percent early distribution penalty on amounts you keep. A direct rollover to an IRA or your current employer's plan avoids all of it and keeps the money growing tax-deferred. Almost everyone taking a buyout should choose the direct rollover box on the election form. Here is the full picture.
Your three payout choices and their tax treatment
| Election | Federal tax now | Penalty risk | Verdict |
|---|---|---|---|
| Direct rollover to IRA or 401(k) | None. No withholding, nothing taxable now. | None. | The default right answer for most people. |
| Check payable to you, rolled over within 60 days | 20 percent withheld up front. You must replace the withheld amount from other money to roll over 100 percent, then reclaim the withholding at tax time. | High. Miss the 60-day window and the whole amount becomes taxable. | An avoidable trap. Do not choose this on purpose. |
| Cash out and keep the money | Fully taxable as ordinary income in one year, on top of your other income. Often pushes you into higher brackets. | 10 percent additional tax if under 59 and a half, with limited exceptions. | Rarely wise for a meaningful balance. |
The under-59-and-a-half penalty, and the age-55 exception
Distributions you keep before age 59 and a half generally owe a 10 percent additional tax on top of ordinary income tax. One notable exception for pension money: if you separated from service with the employer in or after the year you turned 55, distributions from that employer's plan avoid the 10 percent penalty. Careful: that exception applies to money paid from the employer plan, not to money you first roll into an IRA and then withdraw. If you might need funds between 55 and 59 and a half, think before rolling everything to an IRA. IRS Publication 575 covers the details, and this is a spot where an hour with a tax professional is cheap insurance.
What a rollover preserves
- Tax deferral. The full lump sum keeps compounding untaxed until you withdraw it.
- Control of timing. You choose when to realize income, which lets you manage brackets, Medicare premium thresholds, and Social Security taxation year by year.
- Inheritance. IRA balances pass to named beneficiaries. Required minimum distributions eventually apply, as they would to any pre-tax account.
- The option to buy income later. Rolling over does not end the annuity question. You can always use part of an IRA to buy a lifetime income annuity later if you want a pension-like floor.
State taxes and withholding
States tax pension income very differently. Some have no income tax at all, some exempt most retirement income, and others tax it like wages. A direct rollover is not taxable to any state in the year of the rollover, which is one more argument for it: you defer the state question until withdrawals, possibly after a move. Confirm your state's treatment before electing a cash distribution.
Paperwork checklist before you sign
- Open the receiving IRA before the election deadline so the direct rollover has somewhere to land.
- Elect direct rollover on the plan form, with the check made payable to the custodian for your benefit, never to you personally.
- Keep the plan's calculation worksheet and election confirmation with your tax records.
- Expect a Form 1099-R next January. A properly executed direct rollover shows a distribution code that makes it non-taxable.
Frequently asked questions
How much tax will I pay on a pension lump sum?
With a direct rollover to an IRA: none now. Paid to you in cash: it is ordinary income in the year received, with mandatory 20 percent federal withholding up front and a possible 10 percent penalty if you are under 59 and a half.
How do I avoid the 20 percent withholding on a pension payout?
Elect a direct rollover, sometimes called a trustee-to-trustee transfer. The check goes straight to your IRA or new plan custodian and no withholding applies.
Can I roll a pension lump sum into a Roth IRA?
Yes, but it is a Roth conversion: the entire pre-tax amount becomes taxable income that year. Most people roll to a traditional IRA first and convert in measured pieces over several years, if at all.
Does a pension lump sum count as income for Social Security or Medicare premiums?
A direct rollover does not. A cash distribution does count as income and can raise Medicare IRMAA premiums and the taxable share of Social Security for that year.
