How It Works

Involuntary Separation Pay (ISP) under 10 U.S.C. §1174 compensates members separated involuntarily, typically at 6 to 18 years of service: past initial commitment but short of retirement. The full-rate formula is fixed: 10% × years of service × 12 × the monthly basic pay you hold on your last day. Half-rate ISP, used for some separation reasons, is exactly half that. This page pulls monthly basic pay from the 2026 DFAS table for your grade and years.

The lump sum is taxable in the year received, and payroll systems withhold federal income tax at the 22% supplemental-wage rate by default. On a five-figure payment that is a substantial bite, and your actual liability settles at filing. Full ISP generally requires at least 6 years of active service and an honorable discharge; fractional years count by full months.

The rule that catches veterans years later is recoupment. When the VA awards disability compensation down the road, it withholds monthly checks until the lump sum has been recovered. Since 1996 the recoupment is of the after-tax amount for pay that was taxed, but it can still mean years of reduced VA checks. Factor that in before treating ISP as free money.

Example: E-5 Involuntarily Separated at 8 Years

  1. 1 A staff sergeant (E-5) is involuntarily separated at 8 years. The 2026 monthly basic pay for E-5 at 8 years is $4,300.20.
  2. 2 Full ISP: 10% × 8 × 12 × $4,300.20 = $41,281.92 gross.
  3. 3 Federal withholding at the 22% supplemental rate takes $9,082.02, leaving an estimated net of $32,199.90.
  4. 4 If the VA later rates them for disability compensation, roughly the net amount is recouped from VA payments before monthly compensation starts flowing.

Frequently Asked Questions

How is involuntary separation pay calculated?
Full ISP = 10% × years of service × 12 × your final monthly basic pay (10 U.S.C. §1174). Half-rate ISP is exactly half. Fractional years count by full months, and the full rate generally requires 6+ years of service plus an honorable discharge.
How is separation pay taxed?
It is taxable income paid as a lump sum, withheld federally at the 22% supplemental-wage rate by default. Your actual liability settles at filing: a large payment can push part of it into a higher bracket, or you may get some withholding back.
Does the VA take back separation pay?
Yes. If you are later awarded VA disability compensation, VA withholds monthly payments until the amount is recouped, and for money that was taxed the recoupment is of the after-tax figure. Disability severance for combat-related conditions is exempt.
Who qualifies for full vs. half separation pay?
Full (10%): involuntary separation while fully qualified for continued service (e.g. RIF or high-year tenure) with 6+ years. Half (5%): separations for reasons like failure to meet standards, when the service authorizes it. Voluntary separations get neither.
