Quick reference
| Item | What the IRS topic says |
|---|---|
| Who may elect optional methods | “If you were born before January 2, 1936, and you receive a lump-sum distribution from a qualified retirement plan or a qualified retirement annuity, you may be able to elect optional methods of figuring the tax on the distribution.” |
| How often | “These optional methods can be elected only once after 1986 for any eligible plan participant.” |
| Rollover window | “You may also be able to defer tax on a distribution paid to you by rolling over the taxable amount to an IRA within 60 days after receipt of the distribution.” |
| Mandatory withholding | “Mandatory income tax withholding of 20% applies to most taxable distributions paid directly to you in a lump sum from employer retirement plans even if you plan to roll over the taxable amount within 60 days.” |
| Form for the tax | “the instructions for Form 4972, Tax on Lump-Sum Distributions.” |
What counts as a lump-sum distribution
The topic defines the term in one sentence. It says “A lump-sum distribution is the distribution or payment within a single tax year of a plan participant’s entire balance from all of the employer’s qualified plans of one kind”. It gives examples of plan kinds: “for example, pension, profit-sharing, or stock bonus plans”.
The payment also has to be made for one of four reasons. The topic lists “Because of the plan participant’s death,” then “After the participant reaches age 59½,” then “Because the participant, if an employee, separates from service, or” and “After the participant, if a self-employed individual, becomes totally and permanently disabled.”
The five treatment options
For eligible people, the topic says “You can elect to treat the portion of a lump-sum distribution that’s attributable to your active participation in the plan using one of five options:” Two of the five are the plain ones. One is “Roll over all or part of the distribution.” and the last is “Report the entire taxable part as ordinary income.”
Another option uses a special calculation. It reads “Use the 10-year tax option to figure the tax on the total taxable amount (if you qualify).” The Form 4972 line walk through on our site is at Form 4972.
Employer stock gets its own paragraph. The topic says “the NUA is generally not subject to tax until you sell the securities.” It adds “However, you may elect to include the NUA in your income in the year the securities are distributed to you.”
Rollovers, withholding and the Form 1099-R
On rollovers, the topic says “You may be able to defer tax on all or part of a lump-sum distribution by requesting the payer to directly roll over the taxable portion into an individual retirement arrangement (IRA) or to an eligible retirement plan.” It warns about the trade off: “If you do a rollover, the regular IRA distribution rules will apply to any later distributions, and you can’t use the special tax treatment rules for lump-sums (described earlier).”
On withholding, it says “Note that the default rate of withholding may be too low for your tax situation.” The form named is “Form W-4R, Withholding Certificate for Nonperiodic Payments and Eligible Rollover Distributions”. See also our page on 20 percent withholding on a pension lump sum.
The payer’s form is addressed too. The topic says “If your Form 1099-R isn’t made available to you by January 31 of the year following the year of the distribution, you should contact the payer of your lump-sum distribution.”

Common mistakes
- Assuming the five options are open to everyone. The topic opens with “If you were born before January 2, 1936”
- Assuming a rollover keeps the special lump-sum tax rules. The topic says “you can’t use the special tax treatment rules for lump-sums (described earlier).”
- Assuming a planned rollover avoids withholding. The topic says it applies “even if you plan to roll over the taxable amount within 60 days.”
- Treating 20% as a fixed limit. The topic says “You may choose to provide the payer Form W-4R”
