A regular officer who is discharged under chapter 36 of this title (except under section 630(1)(A) or 643 of such chapter) or under section 580 or 8372 of this title and who has completed six or more, but less than twenty, years of active service immediately before that discharge is entitled to separation pay computed under subsection (d)(1).

A regular commissioned officer of the Army, Navy, Air Force or Marine Corps who is discharged under section 630(1)(A), 643, or 1186 of this title, and a regular warrant officer of the Army, Navy, Air Force or Marine Corps who is separated under section 1165 or 1166 of this title, who has completed six or more, but less than twenty, years of active service immediately before that discharge or separation is entitled to separation pay computed under subsection (d)(1) or (d)(2), as determined by the Secretary of the military department concerned, unless the Secretary concerned determines that the conditions under which the officer is discharged or separated do not warrant payment of such pay.

Notwithstanding paragraphs (1) and (2), an officer discharged under any provision of chapter 36 of this title for twice failing of selection for promotion to the next higher grade is not entitled to separation pay under this section if either (or both) of those failures of selection for promotion was by the action of a selection board to which the officer submitted a request in writing not to be selected for promotion or who otherwise directly caused his nonselection through written communication to the Board under section 614(b) of this title.

Notwithstanding paragraphs (1) and (2), an officer who is subject to discharge under any provision of chapter 36 of this title or under section 580 or 8372 of this title by reason of having twice failed of selection for promotion to the next higher grade is not entitled to separation pay under this section if that officer, after such second failure of selection for promotion, is selected for, and declines, continuation on active duty for a period that is equal to or more than the amount of service required to qualify the officer for retirement.

A regular enlisted member of an armed force who is discharged involuntarily or as the result of the denial of the reenlistment of the member and who has completed six or more, but less than 20, years of active service immediately before that discharge is entitled to separation pay computed under subsection (d) unless the Secretary concerned determines that the conditions under which the member is discharged do not warrant payment of such pay.

Separation pay of an enlisted member shall be computed under paragraph (1) of subsection (d), except that such pay shall be computed under paragraph (2) of such subsection in the case of a member who is discharged under criteria prescribed by the Secretary of Defense.

If the Secretary concerned determines that the conditions under which a member described in paragraph (1) is discharged or separated do not warrant separation pay under this section, that member is not entitled to that pay.

A member described in paragraph (1) who was not on the active-duty list when discharged or separated is not entitled to separation pay under this section unless such member had completed at least six years of continuous active duty immediately before such discharge or release. For purposes of this paragraph, a period of active duty is continuous if it is not interrupted by a break in service of more than 30 days.

10 percent of the product of (A) his years of active service, and (B) 12 times the monthly basic pay to which he was entitled at the time of his discharge or release from active duty; or

one-half of the amount computed under clause (1).

A member who has received separation pay under this section, or separation pay, severance pay, or readjustment pay under any other provision of law, based on service in the armed forces, and who later qualifies for retired or retainer pay under this title or title 14 shall have deducted from each payment of such retired or retainer pay an amount, in such schedule of monthly installments as the Secretary of Defense shall specify, taking into account the financial ability of the member to pay and avoiding the imposition of undue financial hardship on the member and member’s dependents, until the total amount deducted is equal to the total amount of separation pay, severance pay, and readjustment pay so paid.

A member who has received separation pay under this section, or severance pay or readjustment pay under any other provision of law, based on service in the armed forces shall not be deprived, by reason of his receipt of such separation pay, severance pay, or readjustment pay, of any disability compensation to which he is entitled under the laws administered by the Department of Veterans Affairs, but there shall be deducted from that disability compensation an amount equal to the total amount of separation pay, severance pay, and readjustment pay received, less the amount of Federal income tax withheld from such pay (such withholding being at the flat withholding rate for Federal income tax withholding, as in effect pursuant to regulations prescribed under chapter 24 of the Internal Revenue Code of 1986). Notwithstanding the preceding sentence, no deduction may be made from disability compensation for the amount of any separation pay, severance pay, or readjustment pay received because of an earlier discharge or release from a period of active duty if the disability which is the basis for that disability compensation was incurred or aggravated during a later period of active duty.

A member of the armed forces who receives a sole survivorship discharge shall be entitled to separation pay under this section even though the member has completed less than six years of active service immediately before that discharge. Subsection (e) shall not apply to a member who receives a sole survivorship discharge.

The amount of the separation pay to be paid to a member pursuant to this subsection shall be based on the years of active service actually completed by the member before the member’s sole survivorship discharge.

The Secretary of Defense shall prescribe regulations, which shall be uniform for the Army, Navy, Air Force, Marine Corps, and Space Force, for the administration of this section.

Active commissioned service in the National Oceanic and Atmospheric Administration or the Public Health Service shall be credited as active service in the armed forces for the purposes of this section.
